Anterior segment ischaemia following segmental scleral buckling.

Accepted for publication 24 November 1993 Case report A 55-year-old white man presented with an 8 month history of poor vision in the left eye. He had a history of mild asthma and 2 years previously had suffered a subarachnoid haemorrhage caused by a left middle cerebral artery aneurysm which was subsequently clipped. There was no visual disturbance associated with the subarachnoid haemorrhage. On examination the right eye was normal but left visual acuity was reduced to counting fingers. Funduscopy revealed a left subtotal retinal detachment, involving the macula, associated with two small retinal breaks in the inferotemporal periphery. Retinal reattachment surgery was performed under general anaesthesia. A 3600 conjunctival limbal peritomy was performed, the retinal holes were localised, and transcleral cryopexy to the retinal breaks was performed. Subretinal fluid was drained below the lateral rectus muscle and
