Visual outcomes of surgery for stage 4 and 5 retinopathy of prematurity

摘要

Retinopathy of prematurity (ROP) is a disease of abnormal retinal vascular development that occurs in premature and low-birth weight infants. Screening and treatment guidelines established by the CRYO-ROP and ETROP studies have reduced the rates of stage 4 and 5 ROP and resultant visual loss and are estimated to prevent 320 cases of blindness per year in the United States.1 Despite early treatment of high-risk disease, approximately 1 in 10 cases of ROP will progress to stage 4 or 5 retinal detachments needing surgical repair.2 This number is growing both in developed and developing countries because of advancements in neonatal care and improved survival of extremely premature infants (22 to 26 wk gestational age). In this review, we will discuss the most recent literature regarding; visual and anatomic outcomes after surgery for stage 4 and 5 ROP.
