Abstract
An 18 year old man presented 24 hours after watching the total eclipse without appropriate protection. Total exposure time was approximately 20 minutes. During direct viewing the patient kept his right eye closed. One hour after observation he noted blurred vision and a central scotoma on the left eye. Best corrected visual acuity was 0.8 in the right and 0.1 in the left eye. Fundus examination of the right eye did not show any pathology. Funduscopy of the left eye revealed a yellow lesion in the fovea, surrounded by a circular red area (Fig 1). OCT was performed 48 hours after exposure. OCT examination of the right eye showed no pathology. In the left eye, a hyperreflective area in the fovea was found (Fig 2A). All retinal layers in the fovea were affected. The hyperreflective area closely resembled the yellow spot seen funduscopically. There was no significant difference in retinal thickness between the right and the left eye (106 μm/110 μm). Nine days after exposure visual acuity was 0.8 in the right eye and 0.16 in the left eye. Funduscopy showed the yellow lesion of the left fovea resolving and its margins beginning to fade. An OCT scan revealed that the previously hyperreflective foveal area converted to a normal reflectivity (Fig2B).
