PURPOSE To report clinical and multimodal imaging features of Best disease in patients presenting with subretinal pigment epithelium hyperreflective lesions. DESIGN Retrospective study. METHODS Clinical examination findings and multimodal imaging features, including color fundus photography, spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence, fluorescein and indocyanine green angiography (ICGA), and optical coherence tomography angiography (OCTA) images were evaluated retrospectively. RESULTS We assessed 27 eyes of 16 patients with the diagnosis of Best disease. Only patients presenting with serous macular detachment and subretinal pigment epithelium hyperreflective lesion in one or both eyes were included in this study. In 17 of 27 eyes (63%), fibrosis was identified by multimodal imaging techniques. Although there was no sign of active neovascularization on fundus examination or SD-OCT, a vascular network could be identified in 7 eyes (26%) (in 1 eye with OCTA only and in 6 eyes with both OCTA and ICGA). Active neovascularization was seen in 3 eyes (11%). Treatment was recommended for eyes with active neovascularization, and follow-up was scheduled for eyes with quiescent neovascularization and fibrosis. CONCLUSION Eyes with Best disease with subretinal pigment epithelium hyperreflective lesion and serous macular detachment may show fibrosis, quiescent neovascularization, or active neovascularization. Multimodal imaging techniques are very important for differentiation of these lesions.
