Purpose: To report a case with gyrate atrophy (GA) complicated by bilateral choroidal neovascularization (CNV) treated with intravitreal bevacizumab.
Case presentation: A 20-year-old man presented with a complaint of sudden visual decrease in his both eyes. Best-corrected visual acuity (BCVA) was 20/400 and 20/500, with a spherical refractive error of -2.00 and -1.75 D, in the right and left eyes, respectively. Dilated fundus examination revealed multiple bilateral, sharply defined chorioretinal atrophy areas in the midperipheral and peripheral zone with the suspicion of CNV in both eyes. Spectral-domain optical coherence tomography revealed bilateral cystoid macular edema consistent with CNV development which was confirmed by fundus fluorescein angiography. Single dose of intravitreal bevacizumab injections were performed to both eyes of the patient. At the first month after the injection, the BCVA improved and OCT revealed scar formation without any intraretinal/subretinal fluid in both eyes. At the first-year follow-up, the maculas remained dry on the OCT and the BCVA was preserved. No additional injections were needed.
Conclusion: Intravitreal bevacizumab might be a treatment alternative, which provides satisfactory anatomical and functional results and leads to a better central vision in cases with GA complicated by CNV.
