Abstract

In Reply.  —We thank Dr Schechter for his interest in our article. Laser photocoagulation applications were placed one-half "burn width" apart to minimize potential complications.Confluent treatment of the avascular area, as is recommended for cryotherapy, will likely induce an absolute visual field defect in the treated region. If laser scatter treatment is applied, it is less likely that an absolute defect will be present throughout the treated area, which may vascularize after resolution of extraretinal fibrovascular proliferation.Late-onset rhegmatogenous retinal detachment is a recognized complication following cryotherapy for retinopathy of prematurity.1 It has been suggested that retinal breaks found at the junction between the treated and untreated part of the retina in those cases occur because the firmly attached treated retina is unable to stretch adequately as the eye grows.1 Intolerable anteroposterior tractional forces may result in tearing of the retina at the junctional zone. We believe
