Overview

Myopia (nearsightedness) is increasing worldwide and is becoming a serious public health problem. Studies estimate that by 2050, if no action is taken, almost half of the world's population will be myopic. About 10% of people could develop severe myopia, which increases the risk of serious eye problems such as retinal detachment, damage to the macula, or glaucoma. Children are particularly affected because myopia often worsens as they grow. Several treatments are now available to slow the progression of myopia in children, but these treatments are not equally effective for everyone. Some children respond better than others, and the reasons for these differences are not yet well understood. One possible explanation is that differences in eye anatomy may influence the effectiveness of a treatment. This suggests that myopia treatments may need to be tailored to each child. By studying the anatomy of the eye, researchers could improve and personalize myopia control strategies. The study entitled "Eye imaging for the study of childhood myopia" aims to better understand the structure of children's eyes. The study will collect clinical data, including images of the eye taken with MRI and measurements of the eye obtained using standard eye examination devices. The data will then be analyzed using image-processing and statistical methods to allow a detailed study of children's eye anatomy.

Interventions

Ophtalmic measurements to estimate geometrical distancesDEVICE

Patients will undergo routine ophthalmic examinations, such as ocular biometry to estimate axial length and corneal topography. Anatomical characteristics will then be derived from the geometric measurements obtained from each device. All measurements are non-invasive and non-ionizing. They all involve conventional ophthalmic devices that are widely used in clinical settings.

MRIDEVICE

Participants will undergo Magnetic Resonance Imaging (MRI) to image their eyes. A head antenna will be used. All measurements are non-invasive.

Ophtalmic measurements to measure wavefront aberrationsDEVICE

Patients will undergo ophthalmic measurements to assess ocular wavefront aberrations. These measurements will be performed using commercially available devices that are widely accepted in routine clinical practice. All procedures are non-invasive and non-ionizing.

Outcomes

Primary Outcomes

Eye anatomy

This set of data will enable an in-depth study of the eye anatomy: MRI will provide anatomical characteristics of the eyeball and its surrounding tissues such as the optical nerve. Ophtalmic measurements will provide anatomical characteristics of the eye's refractive system, such as corneal pachymetry, with optimal geometric resolution. Thus, MRI images and ophtalmic measurements will be combined to study the overall eye anatomy. Period: From inclusion up to 3 months after inclusion
