It is largely based on the management of amblyopia. And to avoid the permanent loss of vision of the deviated amblyopic eye, the only solution is to make it work a lot and as soon as possible, before the child reaches the age of the end of brain plasticity ( a priori up to six or seven years, sometimes a little more, but in all cases before ten years).

This care is based on cooperation between ophthalmologist, parents, orthoptist and childcare professionals. It is up to the ophthalmologist to organize the long-term treatment and to the orthoptist to ensure the controls. For their part, parents and institutions (daycare, school) must really cooperate so that the child wears his glasses properly. Because the stake is to save his deviated eye. To save the vision of an amblyopic eye, it is necessary to mask the eye which sees well to force the eye which sees poorly to work. At first, the healthy eye is masked all day. Subsequently, when the connection between the amblyopic eye and the brain is reestablished again, the masking time of the healthy eye decreases with a relay by filter glasses which aesthetically cannot be seen. It is also necessary to make them wear by the child very seriously: the future vision of the eye which was deviated depends on it. To achieve this, parents must show their child that they themselves attach great importance to it and explain why: a child, even very young, understands better than one might think.
