Article Synopsis
- This case series investigates whether preterm infants with a gestational age of 32 weeks or more and a birth weight over 1500 grams should be screened for retinopathy of prematurity (ROP) earlier than current guidelines.
- At St. Francis Hospital in Uganda, 3 infants required treatment for severe ROP before 30 days of life after receiving unblended oxygen for several days.
- The findings suggest that infants in this category may be at a higher risk of developing severe ROP sooner than previously recommended by existing guidelines.
Purpose: This study compared two imaging grading techniques to assess the utility of longitudinal image-based analysis in retinopathy of prematurity (ROP) screening: (1) time-limited without image comparison (a proxy for bedside indirect ophthalmoscopy, termed sBIO) and time-unlimited with image comparison (for telemedicine grading, termed TELE) screening. We tested two hypotheses: (1) H1: TELE was superior to sBIO for the detection of change (Tempo)-same, better, or worse and (2) H2: granular data of change (e.g.

Methods: A before-and-after retrospective cohort study compared preterm infants < 1750 g or < 34 weeks' gestation before (2022) and after (2023) program implementation. Outcomes included: the proportion with severe ROP, the proportion with Zone III vascularization on first examination, and factors associated with severe ROP.
Purpose: To evaluate whether providing clinicians with an artificial intelligence (AI)-based vascular severity score (VSS) improves consistency in the diagnosis of plus disease in retinopathy of prematurity (ROP).
Design: Multireader diagnostic accuracy imaging study.
Participants: Eleven ROP experts, 9 of whom had been in practice for 10 years or more.
Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Not only do the epidemiologic determinants and distributions of patients with ROP vary worldwide, but clinical differences have also been described. The Third Edition of the International Classification of ROP (ICROP3) acknowledges that aggressive ROP (AROP) can occur in larger preterm infants and involve areas of the more anterior retina, particularly in low-resource settings with unmonitored oxygen supplementation.
