Ophthalmology – Eyelid Laceration

Eyelid lacerations are traumatic cuts or tears involving the eyelid and may result from sharp trauma, blunt trauma, or diffuse facial trauma. They can involve the non-marginal eyelid, eyelid margin, or canalicular drainage system, sometimes with associated avulsion of the medial canthal tendon. Because eyelid trauma can coexist with serious ocular and orbital injuries, the first priority is always to exclude globe rupture, intraocular injury, orbital foreign body, optic nerve injury, and facial fractures.

Approximately 25% of eyelid injuries involve the eyelid margin, while around 15% involve the canalicular system. Canalicular lacerations are particularly common in young adults, with an average age around 24 years, and occur predominantly in males. Protective eyewear is important for prevention during hazardous work and recreational activities. Appropriate protective glasses should meet recognized standards such as ANSI Z87.1.

Pathophysiology and Mechanism

Sharp objects can directly cut through the eyelid skin, margin, or lacrimal drainage structures. Reported causes include fingernails, scissors, pencils, glass, tree branches, fishing equipment, and door handles.

Blunt or diffuse trauma can tear the eyelid by traction rather than direct penetration. Sudden lateral displacement of the eyelid can disrupt the medial canthal tendon and canaliculi, which is particularly important in injuries such as dog bites.

Eyelid lacerations frequently coexist with deeper injury. About 44% of eyelid trauma may be associated with globe injury, and patients with canalicular injuries may also have globe rupture, facial fractures, optic neuropathy, retinal detachment, or head trauma.

Diagnosis

The patient should first be stabilized for any life-threatening trauma. Once stable, a detailed history should establish when and how the injury occurred, including the type, direction, and velocity of the traumatic object. The mechanism can suggest an occult orbital or intraocular foreign body.

Previous visual status and tetanus immunization status should also be documented.

A complete ophthalmic examination is essential. Visual acuity should be checked whenever possible, and the clinician should carefully assess for open globe injury before manipulating the eyelid.

The laceration should be evaluated for its length, depth, and location. Determine whether it is partial or full thickness and whether the eyelid margin is involved.

Visible orbital fat prolapsing through the wound is an important finding because it indicates violation of the orbital septum and raises concern for deeper orbital injury, including possible levator damage.

Any laceration located medial to the punctum should be considered suspicious for canalicular injury until proven otherwise.

Diagnostic Testing

If the injury is small externally but resulted from penetrating trauma, there may still be a deeply retained foreign body. When the history or examination raises concern for an occult orbital foreign body, thin-cut CT of the orbits without contrast, with axial and coronal imaging, is generally appropriate.

When canalicular damage is suspected, an ophthalmologist may perform probing and irrigation of the lacrimal drainage system to determine whether the canaliculus has been disrupted.

Treatment

Tetanus immunization should be updated as appropriate.

Antibiotic use depends on the nature of the injury. Routine oral antibiotics for uncomplicated clean eyelid lacerations are not always necessary, but they may be considered based on contamination and mechanism. Animal and human bite injuries warrant prophylactic systemic antibiotics because of the increased risk of infection.

If the globe is intact, the wound can be kept moist with an appropriate dressing while awaiting definitive repair.

An apparently large tissue defect does not always mean that eyelid tissue has been lost. The skin and orbicularis muscle often retract after injury, creating the appearance of missing tissue. True tissue loss is less common but requires more complex reconstruction, often by an oculoplastic surgeon.

Surgical Repair

Repair may be performed in a procedure room or operating room depending on the extent of injury, patient cooperation, associated trauma, and need for sedation or general anesthesia.

Any globe injury should be repaired before the eyelid laceration.

Repair is generally performed within approximately 24–48 hours, although the exact timing depends on contamination, associated injuries, and tissue condition.

Simple non-marginal lacerations may be closed in layers. Deeper tissues can be approximated with absorbable sutures, followed by careful skin closure.

Eyelid-margin lacerations require precise anatomic repair to restore the normal contour and avoid postoperative notching, trichiasis, or poor eyelid-globe apposition. These injuries should be managed by an ophthalmic surgeon experienced in eyelid repair.

Canalicular lacerations require specialized repair, frequently using silicone intubation. Options include monocanalicular stents, such as a Mini-Monoka, or bicanalicular systems such as Crawford tubes, depending on the pattern of injury.

Follow-up

After repair, a thin layer of topical antibiotic ointment is generally applied to the wound several times daily.

Follow-up is commonly arranged within 3–7 days, depending on the severity and complexity of the injury. Patients with associated ocular trauma require follow-up appropriate to those injuries as well.

Hospital admission is usually unnecessary for an isolated eyelid laceration, but patients with a ruptured globe or significant associated trauma may require inpatient management.

Patient Education

Patients should be instructed to watch for signs of wound infection, particularly increasing redness, swelling, tenderness, pain, or discharge.

They should also be advised to return promptly for worsening vision, increasing ocular pain, new diplopia, or excessive tearing, because these symptoms may indicate associated ocular injury or lacrimal drainage complications.

Prognosis

The prognosis is usually very good when the injury is properly evaluated and anatomically repaired. Most patients achieve satisfactory functional and cosmetic outcomes.

Complications

Possible complications include infection, persistent tearing from canalicular obstruction, trichiasis, lagophthalmos with corneal exposure, eyelid-margin notching, and displacement of a silicone lacrimal stent.

Some patients require secondary procedures to correct persistent eyelid deformity, lacrimal dysfunction, or cosmetic abnormalities.
