Optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) findings were evaluated after retinal artery branch occlusion
OCT examination showed increased thickness and hyperreflectivity in the inner retinal layers, and decreased reflexivities in the photoreceptor layer and retinal pigment epithelium. Foveolar depression, foveal photoreceptor layer and underlying retinal pigment epithelium were normal. In FFA, slowing of arterial flow and filling defects were observed. Repeated examinations in the late period revealed atrophy in the inner retinal layers and thinnig at the neuroretinal rim. OCT findings are consistent with intracellular edema in the inner retinal layers, resulting from denaturation and destruction of ischaemic intracellular proteins, and late atrophy.
OCT studies provide useful information on intracellular edema in the early retinal layers of the arterial branch occlusion with fundus examination and later on atrophy, and provide important clues to the pathophysiology of the event.
