A 53-YEAR-OLD man with type 2 diabetes mellitus complaining of decreased vision was referred to our clinic. His best-corrected visual acuity was 20/40 OD and 20/30 OS. His history was remarkable for habitual cocaine use and prolonged, direct viewing of the sun. For example, he recalled staring at the rising sun for approximately 1 hour each morning, at least 2 days per week, during a 3-year period. He stated that after several observations, he could perceive the corona surrounding the sun.
