Spontaneous hyphaema with abnormal iris vessels.

A woman aged 42 was examined in the Casualty Department of the Royal Eye Hospital, London, at 8.30 p.m. on June 30, 1956. She complained of slight blurring of right vision associated with a little pain which had begun 7 hours before. This had never occurred previously. There was no history of physical strain or excitement, nor was there any relevant family or personal history concerning her ocular or general condition. Examination.-Visual acuity was 6/9 in the right eye and 6/6 in the left eye uncorrected. External examination of the right eye showed no abnormality. A fine stream of blood was squirting without pulsation into the aqueous humour from a small ovoid sac attached to the pupillary margin at 11 o'clock. This well-defined stream descended in the aqueous humour to form a thin layer of blood in the lower part of the anterior chamber. Although the stream was continuous the amount of blood in the anterior chamber did not increase, suggesting that it was being removed from the angle as quickly as it was collecting. Occasional slight irregularities in this flow caused "mushrooming" in its course (Figure).
