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...

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...

Area of Science:

Ophthalmology
Surgical Management
Anterior Segment Pathology

Background:

Primary iris stromal cysts are rare ocular tumors.
Rapid growth can lead to significant visual impairment.

Observation:

A 14-year-old presented with vision obstruction and photophobia due to a large iris stromal cyst.
Anterior segment OCT and ultrasound biomicroscopy confirmed the cyst's size and location.
Iris angiography revealed vascularization of the cyst surface.

Findings:

Histopathology showed stratified squamous epithelium with goblet cells.
A combined surgical approach (aspiration, resection, cryotherapy, laser) achieved complete cyst eradication.
Visual acuity improved significantly, and no recurrence was observed at 6 months.

Implications:

Complete removal of epithelial cells is crucial for preventing recurrence.
This multidisciplinary surgical approach offers a viable solution for primary iris stromal cysts.
Effective management can restore visual function and prevent long-term complications.
