Abstract Purpose:Choroidal neovascularization(CNV)may occur in a variety of uveitides, including Vogt-Koyanagi-Harada disease(VKH). It is sometimes difficult to distinguish CNV from inflammatory lesions only by conventional multimodal imaging including dye-based angiographies. The authors present a case of an active CNV secondary to VKH that was detected immediately using optical coherence tomography angiography(OCTA)and treated successfully.

Case:A 46-year-old woman presented with decreased visual acuity and pain in both eyes and headache.

Findings and Clinical Course:The patient's best-corrected visual acuity was 0.5 in the right eye and 0.6 in the left. Ciliary hyperemia, keratic precipitates, inflammatory cells in the anterior chamber and the anterior vitreous, and multiple serous retinal detachment(SRD)were observed in both eyes. She was diagnosed with VKH and received steroid pulse therapy. The right eye had three recurrent attacks, in which SRD developed. SRD resolved after sub-Tenon triamcinolone acetonide(STTA)injection for each recurrent attack. After the third STTA injection, subretinal hyperreflective material(SHRM)and cystoid macular edema(CME)developed. Dye-based angiographies revealed the possible presence of CNV, but they were inconclusive. OCTA confirmed the presence of CNV. A diagnosis of CNV secondary to VKH was made, and she received an intravitreal anti-vascular endothelial growth factor injection. CNV then became inactive, and CME resolved.

Conclusion:OCTA can be a useful tool for detecting CNV secondary to VKH. When SHRM is found in a patient with VKH, OCTA should be performed with underlying CNV in mind.
