Haemorrhage into the lens; a complication of intra-ocular surgery.

Treatment.-Gutt. pilocarpine 1 per cent. four times a day failed to 'control the intraocular pressure, which varied between 45 and 79 mm. Hg Schiotz. On December 10, 1956, a filtration operation was performed, consisting of combined anterior flap sclerotomy, cyclodialysis, and basal iris inclusion (Stallard, 1953). There were apparently no operative complications. On the sixth post-operative day the fundus reflex was lost and a haemorrhage was noted "on the surface" of the lens, but slit-lamp examination later the same day revealed the haemorrhage to be within the lens. There was no trace of hyphaema in the anterior chamber. The anterior surface of the lens appeared intact, there being no visible tear in the lens capsule. The haemorrhage had spread down from the upper nasal quadrant covering the whole of the pupillary area except for a narrow crescentic space on the infero-temporal side through which a faint fundus reflex could be obtained. The edges of further blood films were noted in the deeper layers. The lens sutures were seen as dark lines against the lower edges-of these sheets of haemorrhage. Deeper parts of the anterior cortex and nucleus were obscured from view except in the infero-temporal quadrant where they were free from blood (Fig. 1 opposite).
