X-linked myopia in Danish family.

X-linked infantile myopia is described in a family of 273 members of whom 87 were examined in the National Eye Clinic. The disease may represent a new ocular syndrome, constituted by myopia combined with astigmatism, impaired vision, hypoplasia of the optic nerve heads, and deuteranopia. Obligate carriers presented slight retinal changes. Linkage studies are in progress.
