Electrical activity of the eye in high myopia.

This is the authors' abstract. We don't add key points for this paper.

IT IS generally agreed that simple myopia and degenerative myopia are separate conditions, the former being a normal chance variant in the biological series which includes emmetropia and hypermetropia (Duke-Elder, 1949) and the latter a patho- logical condition. Degenerative myopia in its advanced stage consists of an associa- tion of defects: a highly myopic refraction, chorio-retinal degeneration and atrophy, thinning of the posterior sclera, and an increased axial length of the eye. Additional defects, such as cupuliform cataract, glaucoma, and retinal detachment, are relatively common in patients with degenerative myopia, and a hereditary element is often present. In the investigation here reported the function of eyes with degenerative myopia has been studied using electroretinography and electro-oculography.
