ABSTRACT
PURPOSE: To evaluate the role of repeated intravitreal methotrexate as an adjunct to pars plana vitrectomy in the management of rhegmatogenous retinal detachment with choroidal detachment. METHOD: The authors compared anatomical and visual outcomes of rhegmatogenous retinal detachment with choroidal detachment eyes that underwent pars plana vitrectomy with (Group B) or without repeated intravitreal methotrexate (Group A). RESULTS: The study included 25 eyes of 25 patients, 16 eyes in Group A and nine in Group B. Both groups had similar baseline characteristics. In Group A, successful retinal attachment was achieved in 50% as compared with 89% in Group B; however, the difference was not statistically significant ( P = 0.08). Also, Group B had a significantly greater change in visual acuity from baseline to the last follow-up visit (1.6 + 1.5 logMAR units) compared with Group A (1.18 + 1 logMAR units) ( P = 0.05). There were no significant safety concerns with the use of intravitreal methotrexate. CONCLUSION: Repeated intravitreal methotrexate after vitrectomy for rhegmatogenous retinal detachment with choroidal detachment improves outcomes without posing major safety concerns. Nonetheless, further investigation is necessary to establish the optimal intravitreal methotrexate dosage and duration to prevent recurrence effectively.
