Descemetocoele from exposure keratopathy.

Area of Science:

• Ophthalmology
• Neurology

Background:

• Facial nerve palsy can compromise eyelid function, leading to incomplete closure.
• Exposure keratopathy is a significant risk in patients with facial nerve palsy due to inadequate corneal protection.

Observation:

• A case presented with descemetocoele, a serious complication of exposure keratopathy.
• The descemetocoele was secondary to facial nerve palsy, highlighting the link between neurological deficits and ocular surface disease.

Findings:

• A central tarsorrhaphy was performed to protect the cornea and prevent further ocular morbidity.
• Two-week follow-up showed no progression of the eye condition, indicating the efficacy of the surgical intervention.

Implications:

• Central tarsorrhaphy is a viable surgical option for managing severe exposure keratopathy secondary to facial nerve palsy.
• Prompt intervention can prevent further vision loss and preserve ocular health in at-risk patients.
