Pupillary distortion after contact transscleral diode laser cyclophotocoagulation

Abstract

Editor,—In recent years, transscleral contact diode laser cyclophotocoagulation (TCDLC) has been shown to be efficient in successfully lowering the intraocular pressure in different types of glaucoma.1-5 Reported success rates by various criteria ranged from 38% to 85%. Mostly, a fixed distance from the corneoscleral limbus with a specially designed contact probe without visualisation of the ciliary body is used. Complications reported so far include phthisis, chronic hypotony, corneal graft decompensation, macular pucker, cystoid macular oedema, hyphaema, vitreous haemorrhage, loss of visual acuity, retinal detachment, conjunctival burns, uveitis, and ocular pain.1-5 However, with the increasing use of TCDLC, more complications may be observed. This report describes pupillary distortion, a previously unreported complication. ### CASE REPORT A 32 year old man with bilateral juvenile glaucoma since 1987 was referred …
