Case 33

Patient Presentation: A 56-year-old male presented to the eye clinic with acute onset of metamorphopsia x 3 days in the left eye. His past ocular history is significant for myopia. He was seen 7 months prior in eye clinic and had a stable eye examination. On examination today, his vision was 20/200 in the left eye compared to 20/60 at his last eye examination 7 months prior. There was no RAPD. His slit lamp examination demonstrated mild nuclear sclerosis. Fundus examination demonstrated a myopic fundus with no obvious new changes in the macula. An OCT macula was performed today and compared with the OCT seven months ago.
