Abstract
PURPOSE: To describe the outcome of ultra-low-dose (boom-boom) radiotherapy for choroidal lymphoma. METHODS: Retrospective series of three consecutive patients with biopsy-proven choroidal lymphoma treated with ultra-low-dose radiotherapy. RESULTS: The three patients (two male, one female) of mean age 70 years (range, 64-74 years) demonstrated presenting visual acuity in the affected eye between 20/40 and 20/50. The choroidal lymphoma was unilateral in all cases and presented with multifocal yellow patchy choroidal infiltration, located in all four quadrants and measuring mean 2.9 mm (range, 1.9-4.0 mm) in thickness by ultrasonography. Anterior epibulbar extension of 5 mm diameter was noted in one case. By enhanced depth imaging optical coherence tomography, the choroidal infiltration demonstrated classic undulating appearance (n = 3), with subretinal fluid (n = 2) and intraretinal edema (n = 1). There was no systemic lymphoma in any case. Biopsy was performed in all three cases and was diagnostic (n = 1) or suggestive (n = 2) of B-cell lymphoma. Management involved ultra-low-dose radiotherapy (4 Gy delivered in two fractions, "boom-boom"). On follow-up (mean = 14 months, range = 6-24 months), complete tumor regression on ophthalmoscopy was documented in all three cases, with enhanced depth imaging optical coherence tomography and ultrasonography demonstrating evidence of lymphoma resolution and visual acuity improvement to 20/25-20/40. There were no radiation complications. CONCLUSION: In this small case series, ultra-low-dose (boom-boom) radiotherapy was effective for choroidal lymphoma with favorable response and minimal side effects.
