Brief summary

The main hypothesis is that exposure to repeated shocks is associated with a greater decrease in the thickness of optical nerve fibres. In order to show a association between the occurrence of concussions (in number and severity) and the variation in the thickness of the retinal nerve fibre layer, all participating rugby players will have an ophthalmologic examination (OCT and (retinophotography) at the beginning and end of the Rugby season.

Interventions
