Title	Refraction and genetics
Abstract Nr.	1043

Purpose	Refraction errors are a public health stake. Environment and genetics are surely implicated. In our daily practice, we all have "family of" ametropic patients. We could therefore wonder which part genetics can explain.
Methods	Reviewing studies about refractive errors.
Results	Myopics, hyperopic and astigmatics patients have been studied. Much more has been said about myopia. Genetics seems to be determinant in each refractive error, but locating the genes is a challenging program.
Conclusion	Genetics is a relevant underlying cause of ametropia. The future (molecular genetics) should reveal us the responsible genes or the interaction between environment and predisposing genes.
