UNDERSTANDING PHACOLYTIC GLAUCOMA
Pathophysiology:
-
Phacolytic glaucoma results from inflammatory processes initiated by the leakage of lens material through a mature cataract capsule.
-
Altered lens protein and inflammatory cells obstruct the trabecular meshwork, precipitating glaucoma.
Diagnosis:
-
Recognize phacolytic glaucoma by symptoms of eye pain, photophobia, and severe conjunctival hyperemia, particularly in older individuals with pre-existing vision problems.
-
Diagnosis involves observing prominent cell or particle accumulation in the anterior chamber, a flare reaction without keratic precipitates, corneal edema, elevated intraocular pressure, and evidence of a mature cataract.
-
Pseudohypopyon may also be present, characterized by lens protein deposits layering in the inferior angle.
-
Gonioscopy typically reveals an open anterior chamber angle.
Management:
-
Initiate treatment with topical cycloplegia, steroids, and aqueous suppressants to alleviate inflammation and reduce intraocular pressure.
-
The primary goal is to reduce inflammation and intraocular pressure promptly.
-
Definitive treatment involves cataract extraction to address the underlying cause of phacolytic glaucoma.
​
Pearls:
-
Recognizing the unique clinical presentation of phacolytic glaucoma is essential for accurate diagnosis and timely intervention.
-
Effective management strategies focus on reducing inflammation and intraocular pressure to prevent optic nerve damage and preserve vision.
-
Cataract extraction offers definitive treatment and addresses the underlying cause of phacolytic glaucoma, improving outcomes and patient satisfaction.
