Summary
Uveal prolapse through a cataract incision can mimic eye tumors like melanoma. This condition, presenting as a pigmented epibulbar mass, should be considered in differential diagnoses.
Area of Science:
- Ophthalmology
- Surgical Complications
Background:
- Pigmented epibulbar masses can be challenging to diagnose.
- Differential diagnoses include conjunctival melanoma and uveal melanoma.
- Cataract surgery complications can present with varied clinical signs.
Observation:
- An 88-year-old woman presented with an enlarging pigmented epibulbar mass.
- The lesion mimicked conjunctival melanoma or extraocular extension of uveal melanoma.
- Closer evaluation revealed prolapsed uveal tissue through a prior cataract surgery wound.
Findings:
- The epibulbar mass was consistent with prolapsed uveal tissue.
- The prolapse occurred through partial wound dehiscence from cataract surgery 3 years prior.
- This finding highlights a rare presentation of a common surgical complication.
Implications:
- Uveal prolapse should be included in the differential diagnosis of pigmented epibulbar masses.
- Accurate diagnosis is crucial to avoid misidentification as malignancy.
- Understanding this complication aids in managing post-cataract surgery patients.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
