Summary
Gamma Knife radiosurgery effectively treated symptomatic choroidal hemangioma (CH) with exudative retinal detachment (RD). Patients experienced improved vision and RD resolution without recurrence or radiation toxicity after a 10 Gy marginal dose.
Area of Science:
- Ophthalmology
- Neurosurgery
- Radiation Oncology
Background:
- Choroidal hemangioma (CH) often causes visual disturbance due to exudative retinal detachment (RD).
- Management of symptomatic CH with RD remains a clinical challenge.
Purpose of the Study:
- To evaluate the efficacy and safety of Leksell Gamma Knife radiosurgery for symptomatic CH with exudative RD.
Main Methods:
- Retrospective analysis of seven patients with symptomatic CH and macula-involved exudative RD treated with Leksell Gamma Knife.
- A marginal dose of 10 Gy was prescribed to the target.
- Mean follow-up was 34.4 months.
Main Results:
- Complete resolution of exudative RD within six months in all patients.
- Significant improvement in visual acuity.
- No recurrence of RD or symptomatic radiation toxicity observed.
Conclusions:
- Gamma Knife radiosurgery is a safe and effective treatment for symptomatic CH with exudative RD.
- A marginal dose of 10 Gy is well-tolerated and achieves favorable outcomes.
