Multifocal Retinopathy

Retinal pigment epithelial dysplasia causing localized multifocal retinal detachments

Symptoms
In the mild form, no vision disorders are reported despite the abnormal retina. In the severe form, lesions can lead to blindness.

Gene involved

Mutation tested
c.73C>T (CMR1)

Transmission mode : Autosomal recessive
