Ophthalmology – Conjunctival Lymphoma
Conjunctival lymphoma is part of a spectrum of lymphoid tumors ranging from benign reactive hyperplasia to malignant lymphoma. It represents a form of extranodal lymphoma, meaning it arises outside lymph nodes, and accounts for a small proportion of all lymphomas. Within the eye, lymphoma can involve multiple structures including the conjunctiva, orbit, eyelid, uvea, retina, and vitreous. Importantly, conjunctival lymphoma may be the first manifestation of a systemic, potentially life-threatening lymphoma, making early recognition critical.
Clinically, it most often affects middle-aged to older adults and is rare in children. Patients may present with a painless, pink (“salmon-patch”) conjunctival mass, which is a key hallmark. Some individuals notice irritation, tearing, or a visible lesion, while others are completely asymptomatic. The tumor commonly arises in the fornix or midbulbar conjunctiva and can occasionally be multifocal or bilateral. Although many cases are initially localized, a significant proportion of patients may later develop systemic lymphoma, sometimes even decades after the ocular diagnosis.
The underlying pathophysiology is not fully understood, but many cases are classified as MALT (mucosa-associated lymphoid tissue) lymphoma. Chronic immune stimulation is believed to play a role, possibly related to infections such as Helicobacter pylori or Chlamydia psittaci, or autoimmune diseases like Sjögren’s syndrome or Hashimoto thyroiditis. Genetic abnormalities, including chromosomal translocations, have also been identified in some cases.
Diagnosis begins with clinical suspicion based on appearance, but definitive diagnosis requires biopsy. Histopathology helps distinguish between reactive hyperplasia, atypical lymphoid proliferation, and true malignant lymphoma. Additional evaluation includes CBC to rule out leukemia, as well as imaging—preferably orbital MRI—to assess for local extension. Because of the risk of systemic involvement, patients require long-term systemic surveillance, often with periodic imaging and medical evaluation.
Management depends on the extent and behavior of the tumor. Small, localized lesions may be treated with complete surgical excision combined with cryotherapy. If the lesion is diffuse or involves critical structures, an incisional biopsy followed by therapy is preferred. Treatment options include radiotherapy, which is highly effective due to the radiosensitive nature of lymphoma, as well as chemotherapy and immunotherapy (e.g., rituximab). Some clinicians also use antibiotics targeting suspected infectious triggers.
Long-term follow-up is essential, as recurrence or systemic progression can occur even many years later. Patients are typically monitored at least twice yearly with ocular exams and periodic systemic evaluation. Prognosis is generally favorable for localized disease, but the risk of systemic lymphoma varies—higher in bilateral cases than unilateral ones. Potential complications include ocular motility problems, ptosis, diplopia, or vision loss, particularly after treatment.

Ophthalmology – Contact Lens Complications
Contact lens complications can occur in any wearer and range from mild irritation to severe, vision-threatening infections. These complications are broadly categorized into infectious (bacterial, fungal, Acanthamoeba), allergic (giant papillary conjunctivitis), hypoxic (overwear-related), toxic (solution-related), and structural changes such as corneal warpage. Although most issues are preventable, improper lens hygiene and overwear remain major contributors.
The most serious complication is infectious keratitis, particularly bacterial keratitis, which presents with pain, redness, photophobia, and decreased vision. On examination, there is typically a dense corneal infiltrate with an epithelial defect, surrounding edema, and sometimes hypopyon. Fungal keratitis appears more fluffy with satellite lesions, while Acanthamoeba keratitis—often linked to exposure to contaminated water (e.g., lakes, tap water)—causes severe pain out of proportion to findings and may show radial keratoneuritis or a ring infiltrate (late sign).
Noninfectious complications are also common. Contact lens overwear leads to corneal hypoxia, resulting in punctate keratitis, subepithelial infiltrates, and corneal neovascularization. Toxic keratitis can occur from improper use of multipurpose solutions or unneutralized hydrogen peroxide, presenting as diffuse epithelial damage. Giant papillary conjunctivitis (GPC) is an immune-mediated reaction characterized by large papillae on the upper tarsal conjunctiva, itching, and mucus discharge, often related to lens deposits or material.
Diagnosis relies on a careful history of contact lens use, hygiene practices, and symptom onset, along with slit-lamp examination. In suspected infections, corneal scrapings for culture and staining are essential to identify the causative organism and guide therapy.
Management depends on the underlying cause. Bacterial keratitis is treated urgently with frequent topical antibiotics (e.g., fluoroquinolones or fortified antibiotics). Fungal infections require antifungals such as natamycin, while Acanthamoeba keratitis is treated with agents like PHMB and propamidine. Noninfectious conditions improve with cessation of lens use, lubrication, and sometimes topical steroids or antihistamines (for GPC). Severe or nonresponsive infections may require corneal transplantation.
Prevention is critical and includes avoiding overnight wear, proper cleaning and storage, regular replacement of lenses and cases, and avoiding water exposure while wearing lenses. Daily disposable lenses significantly reduce risk.
The prognosis is generally good for mild complications, but central or severe infections can lead to permanent vision loss, especially if treatment is delayed or inappropriate (e.g., steroid use in active infection).

Ophthalmology – Conjunctival and Corneal Lacerations
Conjunctival and corneal lacerations are tears or cuts of the ocular surface caused by blunt or penetrating trauma. These injuries range from superficial partial-thickness defects to full-thickness open globe injuries, which are vision-threatening emergencies. They are more common in young males and are frequently associated with occupational or recreational activities where protective eyewear is not used.
Patients typically present with pain, redness, tearing, photophobia, and foreign body sensation. A careful history is critical, especially regarding the mechanism of injury, as high-velocity trauma (e.g., metal-on-metal or BB gun injuries) raises strong concern for intraocular foreign body (IOFB) or globe rupture. Determining the timing of last oral intake is also important if urgent surgery is required.
On examination, minimal manipulation of the eye is essential to avoid worsening a possible open globe injury. Visual acuity should always be checked, but intraocular pressure must not be measured if a full-thickness laceration is suspected. Slit-lamp examination helps assess the size, depth, and location of the wound. Fluorescein staining can highlight epithelial defects, and a positive Seidel test confirms aqueous leakage, indicating a full-thickness laceration. Additional concerning signs include irregular pupil, shallow or deep anterior chamber, hyphema, hypotony, or vitreous hemorrhage. Both eyes must be examined carefully, and eyelid eversion should be performed when safe.
If an intraocular foreign body is suspected, orbital CT scan (thin cuts) is the imaging modality of choice, while MRI should be avoided if metallic material is possible. Even with normal imaging, persistent suspicion of globe injury may require surgical exploration.
Management depends on the severity of the injury. Small conjunctival lacerations without scleral involvement often heal with topical antibiotic ointment alone, while larger ones may require suturing. Partial-thickness corneal lacerations are treated with topical antibiotics and close observation, though some may need suturing if wound edges gape. In contrast, full-thickness corneal lacerations are ophthalmic emergencies requiring urgent surgical repair in the operating room. Patients should be protected with a rigid eye shield, kept NPO, and given systemic antibiotics to reduce infection risk. Antiemetics and pain control are important to prevent increases in intraocular pressure.
Surgical repair focuses on restoring globe integrity, carefully repositioning tissues, removing vitreous traction if present, and achieving watertight closure using fine sutures. Associated injuries such as traumatic cataract or iris damage are usually addressed later. Patients must be counseled about the rare but serious risk of sympathetic ophthalmia, which can affect the uninjured eye.
Close follow-up is required to monitor for complications such as infection, retinal detachment, or wound leakage. Children are at particular risk of amblyopia, requiring prompt visual rehabilitation. Prognosis varies widely depending on the severity of injury, timing of treatment, and presence of complications, with worse outcomes associated with delayed care or severe trauma.

Ophthalmology – Acute Viral Conjunctivitis
Acute viral conjunctivitis is a very common inflammation of the conjunctiva, most frequently caused by adenovirus, which accounts for the majority of cases worldwide. It affects individuals of all ages and is highly contagious, often spreading rapidly in households, schools, and crowded environments. Viral conjunctivitis represents 20–70% of all acute conjunctivitis cases, making it the most common overall cause.
Patients typically present with a red eye that begins in one eye and spreads to the other within a few days, accompanied by watery or mucoid discharge, irritation, and tearing. A history of recent upper respiratory infection or contact with an infected person is common. Compared to bacterial conjunctivitis, the discharge is more watery rather than purulent. Many patients also develop preauricular lymphadenopathy, which is a helpful distinguishing feature.
On examination, findings include conjunctival injection, follicular reaction on the palpebral conjunctiva, and sometimes microhemorrhages. In more severe forms such as epidemic keratoconjunctivitis (EKC), patients may develop pseudomembranes and later subepithelial infiltrates in the cornea, which can cause decreased vision and photophobia. These infiltrates typically appear 7–10 days after onset. Other viral forms include pharyngoconjunctival fever (PCF) and acute hemorrhagic conjunctivitis.
Diagnosis is primarily clinical, although rapid point-of-care adenovirus testing is available and can confirm the diagnosis within minutes. More advanced tests such as PCR or viral culture are rarely needed in routine cases. It is important to distinguish viral conjunctivitis from bacterial, allergic, or more serious ocular conditions.
Treatment is mainly supportive, as there are no FDA-approved antiviral agents for adenoviral conjunctivitis. Recommended measures include frequent use of preservative-free artificial tears, cold compresses, and strict hygiene practices such as handwashing and avoiding shared towels. Topical antihistamines may help with itching. In cases caused by herpes simplex virus (HSV), antiviral therapy such as topical ganciclovir or trifluridine is required.
Topical steroids may be used cautiously in severe cases with pseudomembranes or visually significant subepithelial infiltrates, but they should be avoided in mild disease because they can prolong viral shedding and worsen infection.
The prognosis is generally excellent, with most patients recovering spontaneously within 1–2 weeks. However, some patients—especially those with EKC—may develop persistent subepithelial infiltrates or chronic dry eye symptoms, which can last for weeks to months. Patients should be educated about the highly contagious nature of the disease and advised that antibiotics are ineffective unless a secondary bacterial infection is present.

Ophthalmology – Acute Bacterial Conjunctivitis
Acute bacterial conjunctivitis is a common inflammation of the conjunctiva, the mucous membrane lining the inner eyelids and covering the sclera. It affects individuals of all ages and is particularly frequent in children, where bacteria account for the majority of infectious conjunctivitis cases. The condition is highly contagious and represents a significant portion of primary care and ophthalmology visits.
Patients typically present with a red eye accompanied by purulent (yellow-green) discharge, which often leads to eyelid crusting or “glued eyes” upon waking. Symptoms frequently involve both eyes, though one eye may be affected first. Other features include irritation, tearing, and mild discomfort. Unlike viral conjunctivitis, watery discharge is less prominent, and severe pain or vision loss should prompt evaluation for alternative diagnoses. In hyperacute cases—most notably caused by Neisseria gonorrhoeae—patients may develop copious discharge and rapid progression, posing a risk for corneal damage.
The most common causative organisms include Staphylococcus aureus (more common in adults), Haemophilus influenzae and Streptococcus pneumoniae (common in children), and Moraxella catarrhalis. Chronic cases may be caused by Chlamydia, while hyperacute cases are associated with gonococcal infection. Risk factors include close contact with infected individuals, sinusitis, and immunocompromised states.
Diagnosis is usually clinical, though it can be challenging to distinguish from viral conjunctivitis based on symptoms alone. On examination, findings may include conjunctival injection, papillary reaction, and purulent discharge. Preauricular lymphadenopathy is uncommon in bacterial cases. Laboratory testing (culture or Gram stain) is reserved for severe, recurrent, or nonresponsive cases, or when gonococcal or chlamydial infection is suspected.
Treatment typically involves topical antibiotics, which shorten the duration of symptoms and reduce transmission. First-line options include trimethoprim-polymyxin B or fluoroquinolone eye drops for about 7 days. Hyperacute gonococcal conjunctivitis requires systemic antibiotics such as intramuscular ceftriaxone, often combined with topical therapy and close follow-up due to the risk of corneal ulceration and perforation. Supportive care includes artificial tears, good hygiene, and avoidance of sharing personal items.
The prognosis is excellent, as most cases are self-limiting, even without treatment. However, antibiotics speed recovery and reduce spread. Patients should be advised that they remain contagious for 24–48 hours after starting antibiotics. Follow-up is recommended if symptoms worsen, vision decreases, or there is no improvement within a week. Complications are rare but may include keratitis in severe or untreated cases.

Ophthalmology – Conjunctival Primary Acquired Melanosis (PAM)
Conjunctival primary acquired melanosis (PAM) is an acquired, flat pigmentation of the conjunctiva that typically develops in middle-aged or older adults, most often in individuals with lighter skin. It is usually unilateral, nonhereditary, and slowly progressive, and can involve multiple regions of the conjunctiva including the limbus, bulbar surface, fornix, caruncle, and even the tarsal conjunctiva. Unlike conjunctival melanoma, PAM generally lacks prominent vascularity and appears as a patchy, brown discoloration of the ocular surface.
The clinical importance of PAM lies in its potential to act as a precursor to conjunctival melanoma, particularly when atypia is present. Patients often report a gradually enlarging pigmented area on the eye, although many remain asymptomatic. The condition is more common in Caucasians and has been associated with sunlight exposure, though no single definitive risk factor has been identified.
Pathophysiologically, PAM begins as melanocytic proliferation in the basal layer of the conjunctival epithelium. In cases with atypia, these abnormal melanocytes can extend upward through the epithelial layers and eventually penetrate the basement membrane, transforming into invasive melanoma. Histologically, PAM is classified into two main types: without atypia (benign) and with atypia (premalignant). The risk of progression to melanoma is negligible in PAM without atypia but increases significantly with atypia—especially severe atypia, where transformation risk can be very high.
Diagnosis is primarily clinical, supported by careful slit-lamp examination and documentation of lesion extent (often measured in clock hours). Imaging such as anterior segment OCT may help confirm that the lesion is superficial without deeper invasion. In selected cases, biopsy or cytologic evaluation may be performed to assess for atypia, although some clinicians prefer to proceed directly to treatment without prior manipulation.
Management depends on the extent and histologic features of the lesion. Small areas may be observed, especially if atypia is not suspected. More extensive or suspicious lesions are typically treated with surgical excision combined with cryotherapy to surrounding tissue. For diffuse or recurrent disease, topical chemotherapy agents such as mitomycin C may be used, and in extensive cases, even radiotherapy can be considered. The goal is to eliminate abnormal pigmentation and reduce the risk of malignant transformation.
Lifelong follow-up is essential. Patients are usually monitored every 3–4 months initially, then every 6 months once stability is established. Regular examinations focus on detecting growth, recurrence, or transformation into melanoma.
The prognosis is excellent if PAM remains non-atypical. However, once transformation to melanoma occurs, the prognosis becomes more guarded due to the risk of metastasis. Complications from treatment may include ocular surface issues such as dry eye, scarring, symblepharon, and, rarely, vision loss, particularly in advanced or extensively treated cases.

The prognosis is excellent if PAM remains non-atypical. However, once transformation to melanoma occurs, the prognosis becomes more guarded due to the risk of metastasis. Complications from treatment may include ocular surface issues such as dry eye, scarring, symblepharon, and, rarely, vision loss, particularly in advanced or extensively treated cases.

Ophthalmology – Congenital Hyperpigmented Abnormalities of the Fundus
Congenital hyperpigmented fundus lesions are pigmented abnormalities present at birth, differentiated by their appearance, pattern, and location within the retina or choroid. These lesions arise either from the retinal pigment epithelium (RPE) or melanocytes in the choroid and are usually benign, though some carry systemic associations or require monitoring.
Common entities include:
• Grouped pigmentation (“bear tracks”)
• Congenital hypertrophy of the retinal pigment epithelium (CHRPE)
• Combined hamartoma of the retina and RPE
• Choroidal nevi
• Melanocytoma
• Chorioretinal scars (often from intrauterine infection)
Epidemiologically, these lesions vary in frequency. For example, CHRPE occurs in about 5 per 1,000 individuals, while choroidal nevi are relatively common, present in up to 10–13% of the population.
Risk factors depend on the specific lesion. Notably:
• Multiple or bilateral CHRPE lesions may be associated with Familial adenomatous polyposis
• Combined hamartomas may be associated with Neurofibromatosis type 2
Genetically, CHRPE associated with systemic disease is linked to mutations in the APC gene, while combined hamartomas are associated with NF2 gene mutations. Genetic counseling is recommended when these associations are suspected.
Pathophysiologically, hyperpigmentation results from abnormalities in pigment cell development:
• RPE-derived lesions: CHRPE, grouped pigmentation, combined hamartoma
• Melanocyte-derived lesions: choroidal nevus, melanocytoma
Etiologies include genetic mutations, developmental abnormalities, and in some cases inflammatory or infectious causes (e.g., chorioretinal scars from congenital infections).
Some lesions are associated with systemic disease:
• CHRPE → gastrointestinal polyposis syndromes
• Combined hamartoma → central nervous system tumors (NF2)
• Chorioretinal scars → congenital infections affecting the brain
History should assess:
• Prenatal infection exposure
• Family history of colon cancer or neurologic disease
• Neurologic symptoms (e.g., seizures, developmental delay)
• Exposure risks for infections such as Toxoplasmosis
On examination, a dilated fundus exam is essential. Lesions differ in appearance:
• CHRPE: flat, dark, well-demarcated lesions
• Bear tracks: multiple grouped pigmented spots
• Combined hamartoma: elevated lesion with retinal distortion
• Melanocytoma: deeply pigmented lesion often on the optic nerve
Most lesions are asymptomatic and discovered incidentally, though some may affect vision depending on location.
Diagnostic testing is usually minimal. Imaging such as OCT or B-scan may help characterize lesions. MRI may be indicated when systemic associations (e.g., NF2) are suspected.
Management is generally observation, as most lesions are benign. However:
• Choroidal nevi and melanocytomas require serial monitoring for growth or malignant transformation
• Suspicion of systemic disease warrants referral (e.g., gastroenterology for polyposis syndromes, neurology/neurosurgery for NF2)
Follow-up includes periodic examinations with photo documentation to monitor for changes in size or appearance.
Patient education focuses on:
• Awareness of systemic associations
• Importance of follow-up
• Reporting new visual, neurologic, or hearing symptoms
Prognosis is typically excellent for isolated lesions. However, significance lies in recognizing potential systemic disease associations and rare risks of transformation (e.g., nevus to melanoma).

Ophthalmology – Congenital Hypertrophy of the Retinal Pigmented Epithelium (CHRPE)
Congenital Hypertrophy of the Retinal Pigmented Epithelium (CHRPE) consists of benign melanocytic lesions of the retinal pigment epithelium (RPE). These lesions may be solitary, grouped, or multiple, and their clinical significance ranges from harmless incidental findings to markers of systemic disease.
CHRPE lesions are typically flat, well-demarcated, and darkly pigmented, appearing gray-brown to jet black. Many lesions show characteristic depigmented lacunae (pale areas) or a surrounding halo. They are most commonly located in the superotemporal fundus and usually measure about 1–2 disc diameters, though larger lesions can occur.
Three main patterns are recognized:
1. Solitary CHRPE
These are single, flat lesions with smooth or scalloped borders. They may slowly enlarge over time and can develop increasing depigmentation. They are generally benign and not associated with systemic disease.
2. Grouped CHRPE (“bear tracks”)
These consist of multiple small, round pigmented spots arranged in clusters. They are often unilateral and confined to one retinal quadrant. Despite their striking appearance, they have no systemic associations and are considered benign variants.
3. Multiple bilateral CHRPE associated with Familial adenomatous polyposis
This pattern is clinically important. Lesions are typically:
• Multiple (>4 per eye)
• Bilateral
• Oval with irregular borders
• Often show “fishtail” depigmentation at the edges
These findings may indicate an underlying mutation in the APC gene, a tumor suppressor gene responsible for familial adenomatous polyposis (FAP).
Epidemiologically, CHRPE is found in approximately 1.2% of the population, while FAP occurs in about 1 in 13,000–18,000 individuals. Notably, 70–80% of patients with FAP have CHRPE-like lesions, making this an important ocular marker.
Pathophysiologically, CHRPE arises from hypertrophy and hyperplasia of RPE cells, which contain abundant melanin. Solitary and grouped lesions are typically composed of a single layer of enlarged pigmented cells, while FAP-associated lesions may show multilayering and retinal involvement.
History is crucial, especially in patients with multiple lesions. Clinicians should ask about:
• Family history of colon cancer or polyps
• Gastrointestinal symptoms (e.g., rectal bleeding, abdominal pain)
• Associated tumors or syndromes
On examination, dilated funduscopy reveals the characteristic pigmented lesions. The presence of bilateral, multiple, widely spaced lesions should raise suspicion for FAP and prompt systemic evaluation.
Diagnostic tools include:
• Fundus photography for documentation and monitoring
• Autofluorescence imaging (lesions appear hypoautofluorescent)
• Fluorescein angiography (may show capillary changes)
• Visual field testing (for large lesions causing scotomas)
If FAP is suspected, referral for genetic testing (APC gene) and gastrointestinal evaluation is essential. Screening with colonoscopy or sigmoidoscopy typically begins in childhood (around age 10).
Management depends on the type:
• Solitary and grouped CHRPE: No treatment required; routine observation
• FAP-associated CHRPE: Requires systemic surveillance and management, including possible colectomy depending on polyp burden
Follow-up includes periodic ophthalmic examination with photographic documentation to monitor for growth or changes.
Prognosis for isolated CHRPE is excellent. Lesions may enlarge slowly and can cause localized retinal atrophy, occasionally leading to visual field defects.
The most critical complication is not ocular but systemic--risk of colorectal carcinoma in patients with FAP. Rarely, malignant transformation of CHRPE itself has been reported, but this is exceedingly uncommon.

Ophthalmology – Congenital Pit of the Optic Disc
Congenital pit of the optic disc is a rare developmental anomaly characterized by a small, round, grayish excavation in the optic nerve head. It is usually unilateral and often discovered incidentally during routine examination. However, it can become clinically significant when associated with serous macular detachment, leading to visual symptoms.
The condition is thought to arise from incomplete closure of the embryonic fissure, resulting in a structural defect of the optic nerve head. Fluid dynamics play a key role in its complications. The most widely accepted mechanism suggests that liquefied vitreous fluid enters through the optic pit into the subretinal space, leading to a characteristic two-layered maculopathy: inner retinal schisis and outer retinal detachment. Vitreomacular traction may also contribute to fluid accumulation.
Patients are often asymptomatic if the pit is isolated. When macular involvement occurs, symptoms include blurred vision, metamorphopsia, micropsia, or paracentral scotoma. On examination, the pit appears as a small hypopigmented depression, most commonly located on the temporal side of the optic disc. Visual field defects, particularly arcuate scotomas, may be present. Up to 40–50% of cases develop serous macular detachment, especially with larger or temporally located pits.
Diagnosis is primarily clinical but supported by imaging. Optical coherence tomography (OCT) is essential and typically shows schisis-like separation of retinal layers with subretinal fluid. Fluorescein angiography is usually unremarkable but may show late staining of the pit. Visual field testing helps document functional deficits.
Management depends on the presence of complications. Asymptomatic pits require observation with regular follow-up. In cases with serous macular detachment, treatment options include laser photocoagulation, pars plana vitrectomy with internal tamponade, and sometimes macular buckling. Among these, vitrectomy with induction of posterior vitreous detachment has shown the most favorable long-term outcomes.
The prognosis is variable. While the optic pit itself is typically stable, associated macular detachment can lead to progressive visual loss. Many patients experience significant decline in visual acuity over time, although rare cases of spontaneous resolution have been reported. The main complication is serous macular detachment, which is responsible for most visual morbidity.
