Glaucoma and Peters' anomaly. A clinicopathologic case report.
1Duke University Medical Center, Duke University Eye Center, Durham, NC 27710.
Summary
A patient with Peters' anomaly developed open-angle glaucoma requiring surgery. Microscopic analysis revealed premature aging in the trabecular meshwork, suggesting a link between this rare condition and glaucoma development.
Area of Science:
- Ophthalmology
- Genetics
- Pathology
Background:
- Peters' anomaly is a rare congenital corneal condition.
- Glaucoma is a leading cause of irreversible blindness.
- Open-angle glaucoma can occur secondary to other ocular conditions.
Observation:
- A 26-year-old woman with Peters' anomaly developed open-angle glaucoma.
- Filtering surgery was required to manage the elevated intraocular pressure.
- Trabeculectomy and iridectomy specimens were obtained for analysis.
Findings:
- Light and electron microscopy showed grossly normal anterior-chamber angle structures.
- Abundant broad-banded collagen fibers were observed in the trabecular lamellae.
- These findings suggest premature aging of the trabecular meshwork.
Implications:
- This case highlights a potential link between Peters' anomaly and secondary open-angle glaucoma.
- Premature aging of the trabecular meshwork may be a contributing factor.
- Further research is needed to understand the pathogenesis and long-term management.
