The Retina

Categories: Diseases of The Eye and Ear

This is a delicate membrane, upon the surface of which the
images of external objects are received. Its outer surface is in contact

with the choroid; its inner, with the vitreous (glass) body. Behind it is

continuous with the optic nerve; it gradually diminishes in thickness from

behind forward. The retina is soft, semi-transparent and of a purple tint

in the fresh state. Exactly in the centre of the posterior part of the

retina corresponding to the axis of the eye, and at a point in which the

sense of vision is most perfect, is an oval yellowish spot, called after

its discoverer, the yellow spot or Macula lutea of Sommering.
