​Ophthalmology – Acne Rosacea


Acne rosacea is a chronic inflammatory acneiform disorder that primarily affects the central face, including the nose, cheeks, chin, forehead, and may also involve the eyelids and ocular surface. It commonly presents with facial flushing, persistent erythema, papules, pustules, and a sensation of burning or stinging, often accompanied by dry skin. Ocular involvement is frequent and may manifest as blepharoconjunctivitis with meibomian gland dysfunction, lid margin telangiectasia, recurrent hordeola or chalazia, conjunctival hyperemia, and irritation. In more severe cases, the cornea may be affected, leading to punctate epithelial keratitis, vascularization, infiltration, ulceration, or even perforation. Less commonly, inflammation may extend to the episclera, sclera, or iris.


Rosacea affects approximately 1 in 20 individuals, most commonly between the ages of 30 and 60 years, with no clear sex predilection. It is thought to be more prevalent in fair-skinned individuals of European or Celtic descent, although this may be underrecognized in darker skin due to masking by pigmentation. While no single causative gene has been identified, there is often a familial tendency. The exact etiology remains unclear, with proposed contributing factors including vascular dysregulation, immune and inflammatory mechanisms, environmental triggers, and possibly microorganisms such as Demodex folliculorum. Pathophysiologically, abnormal vascular responses lead to vasodilation and leakage of plasma, which promotes inflammation.


Patients often report a history of facial flushing triggered by environmental or lifestyle factors such as sun exposure, wind, extreme temperatures, exercise, stress, alcohol, or spicy foods. On examination, characteristic findings include diffuse erythema, telangiectasias, inflammatory papules and pustules, and in advanced cases, hypertrophy of sebaceous glands resulting in rhinophyma, which is thickening and purplish discoloration of the nasal skin. Ocular examination may reveal chronic eyelid inflammation, meibomian gland obstruction, and signs of conjunctival or corneal involvement.


Diagnosis is primarily clinical and does not require laboratory testing. Histopathological findings, when assessed, include vascular dilation, perivascular inflammatory infiltrates composed of lymphocytes, plasma cells, and histiocytes, and degeneration of dermal connective tissue with edema and elastosis. In rhinophyma, there is an increase in sebaceous gland tissue. Differential diagnoses include acne vulgaris, lupus erythematosus, seborrheic dermatitis, erysipelas, dermatitis, carcinoid syndrome, tuberculosis, and syphilis.


Management focuses on controlling symptoms and preventing progression, as rosacea is a chronic condition without a definitive cure. First-line treatment typically includes oral tetracyclines such as doxycycline or minocycline, which have both antimicrobial and anti-inflammatory effects. Topical therapies such as metronidazole, azelaic acid, or sodium sulfacetamide may also be used. Lid hygiene is essential in patients with ocular involvement, along with lubricants and, in some cases, short-term topical corticosteroids. More severe or refractory cases may require oral isotretinoin or procedural interventions such as electrocautery for telangiectasias.


Patients should be advised to avoid known triggers, use daily sunscreen, and adopt gentle skincare practices. Dietary modifications, including limiting spicy foods, alcohol, and hot beverages, may help reduce flare-ups. Referral to ophthalmology is important in cases with significant ocular involvement, particularly when there is corneal disease or recurrent eyelid lesions, and dermatology referral may be necessary for severe cutaneous disease or rhinophyma requiring surgical or laser treatment.


Regular follow-up is important to monitor for complications, especially corneal involvement, which can threaten vision if untreated. The overall prognosis is good with appropriate management, although symptoms tend to be chronic and relapsing. Key clinical insights include recognizing that recurrent chalazia or hordeola may indicate underlying ocular rosacea, and that long-term management often relies on a combination of topical and systemic antibiotic therapy along with lifestyle modification.
