Impact of Prematurity on the Optic Nerve

Sponsor: Nantes University Hospital

Summary

The purpose of this protocol is to study the consequences of prematurity on the optic nerve. Indeed, the work already carried out on the subject suggests that prematurity induces suffering of the optic nerve with a loss of optical fibre, an essential element in the transmission of the visual nerve signal to the brain. The investigators will therefore study two populations: a population of premature infants aged 5 to 10 years, and a control population of term infants. The examinations performed are painless, non-invasive and non-irradiating. To date, there are no known adverse reactions to these tests. These examinations are a photo of the fundus (retinophotography), a pachymetry (measurement of the thickness of the non-contact cornea), an OCT RNFL (optical coherence tomography, scanner of the non-irradiating non-painful optical nerve) and the taking of the IOP (intraocular pressure). They aim to measure the main morphological characteristics of the eye and the optic nerve. This is a prospective observational study. The inclusion and measurements necessary for the study are made on the day of the consultation. The expected results will provide new data on this population of premature infants, allowing for better management if a pathology involving the optic nerve were to occur at any age in these patients.
