Angle Closure Glaucoma: Treatment

Angle 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...

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview

Glaucoma: 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...

Summary

A rare conjunctival keratoacanthoma (KA) in an elderly man was successfully treated with surgery and cryotherapy. Differentiating conjunctival KA from squamous cell carcinoma is crucial for appropriate management.

Ophthalmology
Dermatology
Oncology

Background:

Conjunctival keratoacanthoma (KA) is an exceptionally rare tumor, often misdiagnosed.
Distinguishing KA from squamous cell carcinoma (SCCA) is clinically significant.

Observation:

An 83-year-old male presented with a rapidly growing conjunctival mass.
Slit lamp examination revealed a leukoplakic tumor at the temporal limbus.

Findings:

Histopathology confirmed the diagnosis of keratoacanthoma (KA).
The tumor was successfully excised using the no-touch technique, followed by cryotherapy and amniotic membrane application.

Implications:

This case underscores the importance of surgical excision and cryotherapy for conjunctival KA.
Accurate histopathological differentiation between KA and SCCA is vital for optimal patient outcomes.
