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
Ophthalmic Surgery

Background:

Iris defects can result from various conditions including melanotic lesions, trauma, and congenital anomalies.
Restoration of iris function and cosmesis is crucial for patient quality of life.

Purpose of the Study:

To evaluate the efficacy and safety of endocapsular artificial iris implantation for repairing iris defects.
To assess visual outcomes, complication rates, and patient satisfaction following the procedure.

Main Methods:

A retrospective case series of 18 patients who underwent endocapsular artificial iris implantation.
Data collected included patient demographics, surgical indications, postoperative visual acuity, intraocular pressure, and complications.
Follow-up duration was a minimum of 3 months, with an average of 14.1 months.

Main Results:

Nineteen artificial irises were implanted for indications including melanotic lesion excision, trauma, and congenital aniridia.
No significant changes in best corrected visual acuity (BCVA) or intraocular pressure (IOP) were observed postoperatively.
Common complications included transiently elevated IOP (42.1%) and mild prosthesis vaulting (15.7%). Severe complications were rare, affecting 5.3% of patients.
Cosmetic satisfaction was high, with 94.4% of patients expressing significant satisfaction.

Conclusions:

Endocapsular artificial iris implantation is a safe and effective method for restoring iris function and appearance.
The procedure yields favorable functional and cosmetic outcomes with a manageable complication profile.
High patient satisfaction underscores the value of this surgical intervention for iris defects.
