Abstract

Objective: To describe clinical experience with palladium 103 ( 103Pd) ophthalmic plaque radiotherapy for choroidal hemangioma. Methods: One course of 103Pd ophthalmic plaque radiotherapy was used in each of 5 patients with circumscribed choroidal hemangioma who had progressive loss of vision due to subretinal exudation. A mean apex dose of 2900 cGy (2900 rad) was delivered. Functional tests of outcome included best-corrected visual acuity. Anatomic results included changes in tumor height and subretinal fluid documented by ophthalmoscopy, fluorescein angiography, and ultrasonography. Results: All patients had complete resolution of sub-retinal fluid with reattachment of the retina. All. tumors decreased in height (mean, 50%) after treatment. Three patients (60%) demonstrated improvement in visual acuity at the last follow-up, and in 1 patient vision remained stable with resolution of metamorphopsia. Twenty-four months after treatment, 1 patient whose visual acuity had recovered from 20/160 to 20/32 had a loss of vision to 20/160 because of radiation maculopathy. For all patients, a mean visual acuity improvement of 2 lines was documented (95% confidence interval, 0.23-0.88). Mean follow-up was 18.6 months (range, 6-29 months). Conclusions: A single 103Pd plaque radiation treatment was effective in decreasing tumor height, eliminating sub-retinal fluid, and improving visual acuity in patients with symptomatic circumscribed choroidal hemangiomas.
