BACKGROUND: The parameters of the optic disc and peripapillary retinal nerve fibre layer (pRNFL) in premature children may vary with disease processes that contribute to visual impairment and blindness and so could be useful as an objective measure in at-risk children.
METHODS: A systematic review of current literature on the range of pRNFL and optic disc parameters in children aged less than 18 years, who were born before 37 weeks gestation, will be performed. The bibliographic databases MEDLINE, CINAHL, EMBASE, Scopus and Web of Science will be systematically searched. Where possible and appropriate, study-specific estimates will be combined using meta-analysis to obtain an overall summary estimate of pRNFL thickness and cup-disc ratio across studies, and results will be presented by age of population.
DISCUSSION: This review aims to improve understanding of what might be considered within/outside the range of normality for this high-risk group.
