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...

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

Posterior uveal effusion (UE) can occur after cataract surgery. Long-term observation showed normal macular morphology and improved vision, suggesting observation may be suitable for some resistant cases.

Area of Science:

Ophthalmology
Surgical Complications
Retinal Diseases

Background:

Cataract surgery, specifically phacoemulsification with intraocular lens implantation, can rarely lead to posterior uveal effusion (UE).
Posterior UE is characterized by fluid accumulation in the choroid and retina, potentially causing vision impairment.

Observation:

A 64-year-old woman developed diminished vision in her right eye three weeks post-cataract surgery.
Ophthalmic examinations, including OCT and angiography, revealed choroidal folds, subretinal fluid, and choroidal darkening.
Initial treatment with anti-inflammatory and systemic corticosteroids for five months showed no morphological improvement.

Findings:

After a long-term follow-up (43 months post-surgery), optical coherence tomography (OCT) demonstrated normal macular morphology.
Best corrected visual acuity (BCVA) improved to 20/25 without ongoing treatment, indicating spontaneous resolution.
OCT proved to be a reliable tool for monitoring macular changes in posterior UE.

Implications:

Posterior uveal effusion is a rare but possible complication following modern cataract surgery.
Long-term observation may be a viable management strategy for selected cases of posterior UE resistant to conventional therapy.
This case highlights the potential for spontaneous recovery and functional improvement in posterior UE over time.
