Summary
Glaucoma drainage device (GDD) surgery can cause binocular vision disturbances like motility disorders and diplopia. Newer implants may reduce these risks, with management options including prisms or surgery.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Ocular Motility
Background:
- Binocular vision disturbances are known complications following glaucoma drainage device (GDD) implantation.
- The exact pathophysiology remains unclear, potentially involving implant bulk, bleb effects, and surgical trauma impacting muscle function.
Purpose of the Study:
- To review the incidence and management of binocular vision disturbances after GDD implantation.
- To analyze the varying estimates of motility disorders and diplopia from retrospective and recent studies.
Main Methods:
- Review of retrospective, cross-sectional, and prospective studies on GDD implantation outcomes.
- Analysis of reported incidence rates for motility disorders and diplopia.
Main Results:
- Retrospective studies reported high incidences (56%-86% for motility disorders, 57%-75% for diplopia).
- More recent studies estimate incidence between 1%-44%, with newer, smaller bleb implants showing lower rates (1%-5%).
Conclusions:
- Binocular vision disturbances are a significant complication of GDD surgery, though incidence may be decreasing with newer implants.
- Management strategies include prismatic spectacles, monocular occlusion, and strabismus surgery.

01:25Glaucoma: Overview
1000
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...

01:28Angle Closure Glaucoma: Treatment
900
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...

01:27Open Angle Glaucoma: Treatment
771
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
