What Researchers Did
Researchers conducted a systematic review and meta-analysis of 50 studies to evaluate the efficacy of various treatments and prophylaxis for radiation optic neuropathy (RON).
What They Found
The meta-analysis of 1752 patients showed intravitreal anti-VEGF prophylaxis significantly lowered RON incidence by 36% (RR 0.64) compared to control in uveal melanoma patients. Intravitreal anti-VEGF injections, hyperbaric oxygen therapy, and pentoxifylline improved or stabilized vision in 54.5%, 42.9%, and 40.0% of patients, respectively.
What This Means for Canadian Patients
Canadian patients undergoing radiation for uveal melanoma might benefit from intravitreal anti-VEGF prophylaxis to reduce their risk of radiation optic neuropathy. For those who develop RON, treatments like intravitreal anti-VEGF injections or hyperbaric oxygen therapy could help preserve or improve their vision.
Canadian Relevance
This systematic review and meta-analysis was conducted by Canadian researchers, making its findings directly relevant to Canadian healthcare practices and patients.
Study Limitations
A key limitation of the evidence included in this review is that it was primarily limited to retrospective studies.
