Narrow angles as a late complication of treated retinopathy of prematurity
Merriam SW; Merriam WW; Teitelbaum CSJournal of AAPOS 2011; 15: 24
Purpose: Angle closure glaucoma is a known complication of cicatricial retinopathy of prematurity (ROP). We present 6 patients with a history of successfully treated ROP who developed narrow angles, which required treatment. Methods: Retrospective methods were used to study 6 patients. Results: All patients were treated for threshold ROP with either cryotherapy or laser photocoagulation as infants. The age of presentation with narrow angles ranged from 11 to 22 years with one patient being in acute angle closure glaucoma. Visually acuity ranged from 20/25 to light perception. Spherical equivalent refractive error range was -22.00 D to + 0.50 D. Treatment consisted of prophylactic peripheral iridectomies (surgical and laser), tube-shunt surgery, as well as cataract extraction. Discussion: Angle closure glaucoma has been known to occur after regressed or cicatricial ROP. However it is usually not considered an association of treated ROP with a successful anatomical outcome. The patients presented in this series all developed narrow angles several years after the initial treatment. Treatment consisted of peripheral iridectomies, tube-shunt surgery and cataract extraction. Conclusions: Patients who have been successfully treated for ROP may develop narrow angles that could necessitate treatment years after the initial cryotherapy or laser photocoagulation. We think patients like these should be followed with the knowledge that a certain percentage of them will be at increased risk for angle closure glaucoma.
