Summary
BDUMP: Intravitreal methotrexate and rituximab Ongoing injections well-tolerated, improved foveal thickness, and fluid — Retrospective, 5 eyes (3 patients)
Abstract
Purpose: To investigate the utility of intravitreous methotrexate and rituximab in the treatment of Bilateral Diffuse Uveal Melanocytic Proliferation (BDUMP).
Methods: The observational cohort study of five eyes of three patients with BDUMP receiving combination injections of intravitreous methotrexate 400 mcg/0.05 mL and rituximab 1 g/0.1 mL as part of multimodal treatment of BDUMP. Change in central foveal thickness and subfoveal fluid was obtained by optical coherence tomography, and change in logMAR/Snellen vision was compared before and after each injection and over the follow-up duration.
Results: Five eyes of three male patients with BDUMP received 39 combination injections of intravitreous methotrexate and rituximab. The median follow-up period was 48.2 months; all eyes exhibited a decrease in central foveal thickness and subfoveal fluid and an improvement in vision at some point from baseline. The median/mean vision increase was 5/3.4 Snellen lines, decrease in central foveal thickness was 243/235 μ m, and decrease in subfoveal fluid was 240/273 μ m. Over the follow-up period, one eye had a gradual decline in vision from 20/40 to 20/150 over 48 months Four of the 5 eyes had marked improvement and sustained vision: from vision ranging 20/50 to 20/150 at baseline to all 4 improving to 20/25 or 20/20.
Conclusion: Intravitreous methotrexate and rituximab may be a useful, well-tolerated adjunctive treatment for BDUMP. Improvements in central foveal thickness and subfoveal fluid were noted following injections and over the follow-up period. Unlike the often, rapid decline in vision that is expected of this paraneoplastic disease, the eyes in this cohort appeared to have more favorable outcomes.
