To report a case of choroidal neovascularization in a Best disease patient treated with intravitreal bevacizumab injection and followed up with optical coherence tomography angiography (OCTA). CASE SUMMARY: A 20-year-old female visited our clinic with decreased visual acuity of the left eye for 6 months. On optical coherence tomography (OCT), subretinal fluid and hyperreflective subretinal clumps were observed in the macula of the right eye. Subretinal hemorrhage and subretinal fluid were observed in the left eye. Choroidal neovascularization in the left eye was observed using OCTA, fluorescein angiography, and indocyanine green angiography. A full-field electroretinogram was normal in both eyes, but an electrooculogram revealed that the Arden ratio was 1.564 in the right eye and 1.081 in the left eye. Intravitreal bevacizumab injection was performed in the left eye. At 6 months after the intravitreal injection, the best-corrected visual acuity of the left eye had recovered to 20/20. OCT revealed that subretinal fluid reduced and choroidal neovascularization was stable. After 12 months, visual acuity of the left eye was maintained at 20/20, but OCTA revealed that choroidal neovascularization had increased. CONCLUSIONS: Choroidal neovascularization associated with Best disease can improve by intravitreal bevacizumab injection, and the changes in choroidal neovascularization can be followed using OCTA.
