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...

Summary

Eccentric macular holes, a complication of macular surgery, occurred in 11.2% of black African patients. These holes were often multiple and full-thickness, primarily in the temporal macula, impacting visual acuity post-surgery.

Area of Science:

Ophthalmology
Retinal Surgery
Macular Diseases

Background:

Macular surgery, including internal limiting membrane peeling, is a common procedure for retinal conditions.
Complications can arise, necessitating further investigation into their incidence and characteristics within specific populations.

Purpose of the Study:

To determine the incidence and characteristics of eccentric macular holes (EMHs) following macular surgery with internal limiting membrane (ILM) peeling.
To analyze EMH development in a black African population.

Main Methods:

Retrospective case series of 125 patients undergoing macular surgery.
14 eyes of 14 patients who developed EMHs after pars plana vitrectomy with ILM peeling were analyzed.
Outcomes included EMH incidence, location, morphology, and best-corrected visual acuity (BCVA).

Main Results:

The incidence of EMHs was 11.2% in this cohort.
EMHs developed at a mean of 4.4 weeks post-surgery, predominantly in the temporal macula (65%).
Most EMHs were multiple (86%) and full-thickness (64%), with improved BCVA post-intervention.

Conclusions:

Eccentric macular hole formation is a significant complication of macular surgery in this population.
The temporal macula is the most common site for EMHs, which are frequently multiple and full-thickness.
Despite complications, visual acuity showed improvement after surgical intervention.
