A 69-year-oldmanwas admitted from the emergency department of our hospital for subacute onset of visual complaints. The evening before admission, around 10 PM, while watching TV, he experienced binocular and persistent discomposed colors in the lower left visual field (appearing both inside and outside the television screen) that did not change with the direction of gaze. He went to bed and woke up at 1 AM for usual nocturia; then, trying to read his alarm clock, he was unable to understand what time it was despite correctly seeing the numbers. He did not report other visual difficulties at that moment. When he woke again at 3 AM, he had the impression he could not correctly define his position in space and, returning to bed, bumped into a lamp and had the feeling that his head went inside the lamp. At 5 AM, waking up again, he found he was completely blind.
