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...

Intraocular lens prostheses in cataract surgery.

|February 8, 2011

Summary

Intraocular lens prostheses offer benefits for aphakic patients but have drawbacks. Patient age, contact lens intolerance, and cataract type are key considerations for this surgical option.

Area of Science:

Ophthalmology
Biomedical Engineering

Background:

Intraocular lens (IOL) prostheses have been developed to address aphakia, a condition of the eye lacking a lens.
Aphakia can result from cataract surgery or trauma, significantly impacting visual acuity.

Purpose of the Study:

To evaluate the advantages and disadvantages of intraocular lens prostheses in aphakic patients.
To define the indications and contraindications for intraocular lens implantation.

Main Methods:

Review of existing literature on intraocular lens implantation.
Analysis of clinical outcomes and patient selection criteria.

Main Results:

Intraocular lens prostheses offer significant visual rehabilitation for select aphakic patients.

Key indications include advanced age, contact lens intolerance, and monocular cataract.

Contraindications involve young age, monocular vision, and pre-existing ocular conditions that may compromise surgical success.

Conclusions:

Intraocular lens implantation is a valuable option for managing aphakia when balanced against potential risks.
Careful patient selection based on defined indications and contraindications is crucial for successful outcomes.
