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...

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...

Area of Science:

Ophthalmology
Trauma Surgery

Background:

Phacoemulsification and falls are prevalent in the elderly.
This case report addresses a rare ocular trauma in a pseudophakic eye.

Observation:

A 74-year-old female experienced severe eye pain and vision loss after facial trauma from a fall.
Examination revealed total hyphaema, vitreous hemorrhage, and acquired aniridia in a pseudophakic eye.

Findings:

The trauma resulted in complete iris disinsertion and expulsion.
Despite the severe injury, the capsular bag, intraocular lens, and retina remained intact.
Post-treatment visual acuity improved to 6/9.

Implications:

Blunt force trauma can lead to iris disinsertion in pseudophakic eyes.
This injury may be encountered more frequently in emergency and ophthalmology settings.
Awareness of this presentation is crucial for timely diagnosis and management.
