Abstract

Purpose: To study the safety and efficacy of indirect ophthalmoscopy with (Sp) or without (speculum free, SpF) the use of lid speculum and scleral indentation for retinopathy of prematurity (ROP) screening.

Methods: In this crossover randomized controlled trial, preterm infants received either the Sp on their first and the SpF technique on their second examination a week later or vice versa. Video recordings of the infants' reactions were assessed by two observers, using Premature Infant Pain Profile-Revised score and the crying score of the Bernese Pain Scale for Neonates. Fundoscopy adequacy, its duration and adverse events within the first 24 hr postscreening were also recorded.

Results: Thirty-seven infants with median (interquartile range) gestational age of 28.7 (28.0, 30.2) weeks and mean (standard deviation, SD) birth weight 1225 (377) grams were enrolled. The mydriasis-induced stress was similar between the Sp and SpF exam (mean difference [MD]: 0.78, 95% confidence interval [CI]: -0.83, 2.38; p = 0.33). The stress induced by fundoscopy (MD: 4.98, 95% CI: 3.58, 6.37; p < 0.001) and examination overall (MD: 2.32, 95% CI: 0.96, 3.67; p = 0.001) were higher in the Sp than in the SpF exam, and so was the crying score during fundoscopy (MD: 1.31, 95% CI: 1.06, 1.56; p < 0.001). Adverse events in the two groups were similar (p = 0.13). Fundoscopy was adequate in identifying the absence of treatment-requiring ROP in all cases, and lasted longer in the Sp than in the SpF exam (p < 0.001).

Conclusion: Our study suggests that the use of speculum and indentation should be reserved for the few cases where fundus visualization is insufficient for excluding the presence of severe ROP.
