A 72-year-old male patient was referred to us for evaluation of recurrent episodes of loss of vision on his left side. The history of the visual episodes started when he was 52 years old. The patient described precisely how he suddenly lost the vision in the central part of his eyes, and after 5 min perceived flickering, scintillating lights moving to the left part of his visual field (in a zigzag “C” shape), followed by a loss of vision in the inner part of the “C.” The lights gradually moved to the periphery of the left visual field, and vision recovered gradually in the inner area. The total duration of the episode was 20–25 min, after which the vision was perfect again. In the first 10 years he experienced one or two episodes of this type per year. However, the frequency then increased to six to seven episodes per year; nimodipine was prescribed unsuccessfully, with no improvement in the frequency or duration of the episodes. Later still he was started on ticlopidine in the hope that this might reduce the number of episodes.
