Abstract: Purpose: To report the efficacy of dexamethasone 0.7 mg intravitreal implant in recalcitrant radiation retinopathy. Method: Retrospective case report of a single case describing successful treatment of radiation retinopathy with dexamethasone 0.7 mg intravitreal implant following multiple failed attempts with both bevacizumab and focal laser. Results: After the first injection of 0.7 mg dexamethasone the best corrected visual acuity (BCVA) improved from 20/400 to 20/250 and central macular thickness (CMT) decreased. BCVA continued to improve after a second injection to 20/125 and remained stable through the third and fourth injection at 20/150, respectively. The intraocular pressure remained within normal limits. Conclusion: 0.7 mg dexamethasone implant showed benefit in a recalcitrant case of radiation retinopathy.
