Abstract
OBJECTIVE: To address the incidence, treatment outcomes, and risk factors of retinopathy of prematurity (ROP).
METHODS: The medical records were retrospectively reviewed of preterm infants who were examined for ROP at Vajira Hospital during 2015-2020. All demographic data, prenatal, postnatal conditions, ophthalmic findings, and treatment were collected.
RESULTS: Of 142 screened infants, 54 infants (38%) had ROP and 28 of them had sight-threatening ROP (24 infants with prethreshold type 1; 4 infants with prethreshold type 2). All ROP infants were born with a gestational age of fewer than 30 weeks or birthweight less than 1500 g. In multivariate analysis, low gestational age (≤ 30 weeks) and hypoglycemia were associated with any stage of ROP development. While duration of endotracheal intubation of more than 30 days and inguinal hernia were independently associated with severe ROP. Most ROP infants were finally regressed. Only 4 infants were referred out for vitreoretinal surgery.
CONCLUSION: The overall ROP incidence was 38%. Even though a majority of ROP patients recovered, recognizing possible factors helped in ROP detection and progression awareness.
