Study Notes
Here are the study notes in markdown format:
Phacomorphic Glaucoma
- Case-based MCQ:
- A 65-year-old patient presents with sudden vision loss and eye pain in one eye.
- On examination, the eye has a shallow anterior chamber, a mature cataract, and an intraocular pressure (IOP) of 40 mmHg.
- What is the most likely diagnosis?
- A. Acute Angle Closure Glaucoma
- B. Open-Angle Glaucoma
- C. Phacomorphic Glaucoma
- D. Chronic Angle Closure Glaucoma
- Correct answer: C. Phacomorphic Glaucoma
- Rationale: Phacomorphic glaucoma is a type of glaucoma caused by a mature cataract that has become intumescent, leading to a shallow anterior chamber and increased IOP.
- Key features:
- Sudden vision loss and eye pain
- Shallow anterior chamber
- Mature cataract
- Elevated IOP (above 40 mmHg)
- Management:
- Urgent cataract extraction
- Control of IOP with medications
- Monitoring for potential complications (e.g. chronic glaucoma)
