Purpose. To describe the findings of fundus autofluorescence (FAF) and optical coherence tomography (OCT) in patients with branch retinal vein occlusion (BRVO).Methods. In this institutional, retrospective, observational case series, FAF was evaluated in 65 eyes with BRVO in 64 consecutive patients and compared with visual acuity, OCT findings, and other clinical observations.Results. Five types of autofluorescence appeared during the course of BRVO: (1) petaloid-shaped hyperautofluorescence in the area of macular edema and (2) hyperautofluorescence coincident with yellow subretinal deposits. (3) Diffuse hyperautofluorescence appeared within the area of serous retinal detachment (SRD) and OCT showed precipitates on the undersurface of the retina in 5/5 of these eyes (100%). (4) The area of vein occlusion showed diffuse hyperautofluorescence after resolution of the retinal bleeding. (5) Hard exudates exhibited hyper- or hypoautofluorescence. OCT indicated that most of the hard exudates with hyperautofluorescence were located on the retinal pigment epithelium.Conclusions. Hyperautofluorescence associated with subretinal fluid or hard exudate appeared in the subretinal space. This type of hyperautofluorescence may be attributed to blood cell or macrophages. FAF and OCT are noninvasive modalities that provide additional information regarding macular edema due to BRVO.

Even though the diagnosis depends on clinical examination, in cases with branch retinal vein occlusion (BRVO), fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) provide unique data for follow-up, management and prognosis. In FFA, delay of laminar flow phase in the involved branch, hyperfluorescence due to leakage from the vessel wall in the late phases, hypofluorescence due to the blockage by hemorrhage, and soft exudates, and hyperfluorescence due to macular edema can be detected. In OCT, macular thickening, cystic spaces, serous retinal detachment, hyperreflective dots, disorganization of the outer retinal layers – particularly the photoreceptor inner and outer segments line and the external limiting membrane – can be seen. OCTA reveals non-perfusion, particularly in the deep capillary plexus.
