Summary
Radiotherapy shows potential for treating subfoveal neovascularization, especially in patients with better initial visual acuity. Further study is needed to confirm its effectiveness and safety compared to standard treatments.
Area of Science:
- Ophthalmology
- Radiation Oncology
Background:
- Subretinal neovascular membranes, particularly in the subfoveal region, pose treatment challenges.
- Laser photocoagulation for subfoveal neovascularization can cause significant visual acuity loss.
Purpose of the Study:
- To evaluate the efficacy and complications of radiotherapy as an alternative treatment for subfoveal neovascularization.
- To compare radiotherapy outcomes with a control group in a prospective randomized trial.
Main Methods:
- A prospective randomized trial involving 76 patients with subfoveal neovascular membranes.
- Patients were assigned to either radiotherapy (6 x 2 Gy) or a control group.
- Follow-up assessments were conducted at regular intervals up to an average of 15.1 months.
Main Results:
- No significant differences in age or baseline visual acuity between groups.
- Similar visual acuity outcomes at 12 months between radiotherapy and control groups (LogMAR 0.11 vs. 0.09).
- Improved metamorphopsia in 75% of the radiotherapy group; comparable rates of subretinal bleeding in both groups.
Conclusions:
- Current follow-up duration is insufficient to establish radiotherapy as a standard treatment for subfoveal neovascularization.
- Encouraging results in patients with better preoperative visual acuity warrant continued investigation.
