Summary
Sustained-release steroid implants safely lowered intraocular pressure (IOP) and central foveal thickness in glaucoma patients with drainage devices. These implants did not increase IOP or the need for glaucoma medications.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Drug Delivery Systems
Background:
- Glaucoma drainage devices are used to manage intraocular pressure (IOP) in complex glaucoma cases.
- Sustained-release steroid implants offer a localized treatment option for ocular inflammation and edema.
Purpose of the Study:
- To evaluate the effect of sustained-release steroid delivery devices on IOP in eyes previously treated with glaucoma drainage devices.
- To assess the safety and efficacy of intravitreal steroid implants in this patient population.
Main Methods:
- A retrospective case series included 14 eyes with pre-existing glaucoma drainage devices (Ahmed, Baerveldt) receiving steroid implants (dexamethasone or fluocinolone acetonide).
- Outcomes measured included intraocular pressure (IOP), changes in IOP, central foveal thickness, and IOP-lowering medication use.
Main Results:
- Mean IOP showed a trend towards reduction at 1 year (P = 0.032).
- Significant reduction in central foveal thickness was observed (P = 0.001).
- No increase in IOP or need for additional antihypertensive medications was noted; no endophthalmitis occurred.
Conclusions:
- Intravitreal steroid implants are safe and effective in managing postsurgical cystoid macular edema (CME) in patients with glaucoma drainage devices.
- These implants do not appear to elevate IOP or increase medication burden in this specific cohort.

Open Angle Glaucoma: Treatment
390
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.

Glaucoma: Overview
499
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
433
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...
