Traumatic implantation cyst in anterior chamber after cataract extraction.

A male labourer, aged 74, attended the Royal Victoria Hospital, Belfast, complaining of defective vision. Examination.-In the right eye, the visual acuity was reduced to 6/18, because of lens opacities. The left eye showed advanced lens opacities, and the visual acuity was good perception of light. Operation.-On August 4, 1952, an intracapsular extraction of the opaque left lens was performed with a small total iridectomy, and a sclero-corneal silk suture at 12 o'clock closed the wound. Convalescence was uneventful. On September 16, 1952, 6 weeks after operation, the eye was quiescent, with media clear and fundus normal. Visual acuity with glasses was 6/6 and JI. Further Developments.-The patient was next seen 23 months later (July 6, 1954). Visual acuity in the left eye was now 1/60. A triangular deep striate keratitis was present with its base at the limbus from 1 o'clock to 3 o'clock and its apex involving the pupillary area. About half of the anterior chamber was filled by a large transparent cyst which seemed to arise from the limbal area around 2 o'clock (Fig. 1). The ocular tension was 23 mm. Hg (Schiotz).
