Summary
Subretinal neovascularization is a rare complication of retinochoroidal coloboma. This case highlights the importance of monitoring for this condition in affected individuals.
Area of Science:
- Ophthalmology
- Retinal Diseases
Background:
- Retinochoroidal coloboma is a congenital defect.
- Subretinal neovascularization (SRNV) can occur in various retinal conditions.
Observation:
- A 44-year-old female presented with metamorphopsia.
- Bilateral inferior retinochoroidal coloboma was diagnosed.
- SRNV was identified at the coloboma margin using fluorescein angiography.
Findings:
- The patient experienced subretinal hemorrhages that gradually resolved.
- No recurrence of hemorrhage was observed over a six-year follow-up.
- Visual acuity in the affected eye improved to 0.2.
Implications:
- Ophthalmologists must recognize SRNV as a potential complication of retinochoroidal coloboma.
- Awareness of this association can lead to timely diagnosis and management.
- Further research may elucidate the pathogenesis of SRNV in coloboma.
