Summary
Malignant glaucoma, a severe eye condition, can be triggered by immediate cataract surgery for acute primary angle closure. This case highlights a potential complication requiring prompt intervention to prevent vision loss.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Complications
Background:
- Malignant glaucoma involves ciliary block or aqueous misdirection, leading to shallow anterior chambers, high intraocular pressure (IOP), and potential blindness.
- The precise pathogenic mechanisms underlying malignant glaucoma remain incompletely understood.
Observation:
- A 90-year-old woman presented with acute primary angle closure (APAC) and a cataract.
- Initial phacoemulsification surgery for APAC temporarily resolved the high IOP and deepened the anterior chamber.
- Postoperatively, the anterior chamber rapidly shallowed, and the angle narrowed, indicating a return of glaucomatous changes.
Findings:
- The patient was diagnosed with malignant glaucoma one week after phacoemulsification.
- Subsequent treatment with hyaloid-zonulo-iridectomy and atropine eye drops successfully managed IOP and deepened the anterior chamber.
- This case suggests that immediate primary phacoemulsification for APAC can precipitate malignant glaucoma.
Implications:
- Ophthalmologists should consider malignant glaucoma as a potential complication following phacoemulsification for APAC.
- Prompt diagnosis and appropriate surgical and medical management are crucial for preserving vision in such cases.
- Further research into the specific triggers and mechanisms of malignant glaucoma post-cataract surgery is warranted.

Angle Closure Glaucoma: Treatment
584
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
638
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...

Open Angle Glaucoma: Treatment
498
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.
