Abstract
Purpose
There is a large variation in mydriatic regimens used in screening for retinopathy in preterm infants. Except for the standard instillation of mydriatic drops in their commercial formulation, other techniques for pupil dilation have also been described. This study aimed to review all techniques that have been used for mydriasis in retinopathy of prematurity eye examination (ROPEE) screening.
Methods
A comprehensive literature search was performed in PubMed, Cochrane library, Trip database, and Scopus, using the key words: “mydriasis”, “techniques”, “mydriatics”, “dilating drops”, “retinopathy of prematurity”, “ROP”, “phenylephrine”, “cyclopentolate”, “tropicamide”, “smaller mydriatic drops”, “reduction in drop size” to February 2019.
Results
Five primary studies were included, assessing the techniques of microdrops, lower conjunctival fornix (LCF) packing and Mydriasert® ophthalmic insert. Reported efficacy was similar to commercial eyedrops instillation. Microdrops appeared to have a superior safety profile. LCF packing and Mydriasert lead to increased blood pressure, without serious complications, necessitating further safety studies.
Conclusions
Of all alternative mydriasis techniques for ROPEE screening that have been described, microdrops appear to be the safest yet still effective technique in the fragile population of premature infants in risk of ROP.
