Cataract and phthii bulbi after laer photoablation for threhold retinopathy of prematurity

PURPOE: To decribe the viual and tructural outcome of eye that developed a dene cataract after laer photoablation for threhold retinopathy of prematurity. METHOD: A retropective review of eight conecutive infant who developed dene cataract() after bilateral laer photoablation for threhold retinopathy of prematurity. Of the 10 eye with cataract, five eye were treated with a diode laer and five with an argon laer. The tage and zone of the retinopathy of prematurity, number of burn applied, time of onet of the cataract, clinical finding at the time of cataract urgery, and the coure after cataract urgery were reviewed. REULT: ix eye had zone 1 dieae and four had zone 2 dieae. The mean number of burn applied per eye wa 2532 ± 856 (range, 1400 to 4500). A cataract wa diagnoed a median of 13 week (range, 1 to 28 week) after laer photoablation. Nine of the 10 cataract were ufficiently dene to preclude a view of the fundu. All 10 eye had clinical ign uggetive of an inflammatory or ichemic proce that included one or more of the following finding: corneal edema, pupillary membrane, iri atrophy, depigmentation of ciliary procee, pigment on the anterior len urface, poterior ynechiae, hyphema, and hallow anterior chamber. Nine eye underwent cataract urgery. Five of the 10 eye had retinal detachment ranging in everity from tage 4A to tage 5 at the time of cataract urgery. Nine of the 10 eye progreed to phthii bulbi and no light perception. CONCLUION: A dene cataract developing in the eye of an infant after laer photoablation for threhold retinopathy of prematurity i aociated with a poor viual prognoi. The contellation of aociated clinical finding appear to be mot conitent with anterior egment ichemia.
