Outcomes for non-treatment-requiring infants evaluated for retinopathy of prematurity

Abstract

To evaluate the rates of visually significant disorders in patients without treatment-requiring retinopathy of prematurity (ROP) at initial follow-up after completion of ROP examinations. The medical records of all babies evaluated for retinopathy of prematurity between June 2015 and September 2020 were reviewed. Patients with documented gestational age, birth weight, and single versus multiple birth status who did not require ROP treatment and who followed-up with our institution's pediatric ophthalmologist were included. A total of 304 patients were included. Of these, 15 (4.9%) had strabismus (12 [4.0%] with esotropia, 3 [0.9%] with exotropia), 30 (9.9%) had myopia, 174 (57.2%) had hyperopia, 54 (18%) had astigmatism, 4 (1.3%) had amblyopia, 5 (1.6%) were labeled amblyopia suspects, 1 (0.3%) had congenital glaucoma, and 1 (0.3%) had congenital cataract. Nineteen (6.3%) had a condition requiring intervention at the first evaluation following completion of ROP examinations, and in 5 (2%), this was a condition that would typically not have been identified without evaluation by a pediatric ophthalmologist. In our population of infants evaluated for retinopathy of prematurity who did not require ROP treatment, the incidence of other ocular disorders requiring intervention at the first non-ROP evaluation was about 6%. This study highlights the need for further research that may aid in the creation of an evidence-based follow-up strategy for premature infants who never undergo ROP treatment.
