Glaucoma

Abstract

The word “glaucoma” refers to the apparent greygreen colour of the eye suffering from an attack of acute narrow angle glaucoma. Nowadays the term has come to cover a group of eye diseases characterised by raised intraocular pressure. These diseases are quite distinct and the treatment in each case quite different. Glaucoma might be defined as a “pathological rise in the intraocular pressure sufficient enough to damage vision”. This is to distinguish the normal elevation of intraocular pressure seen in otherwise normal individuals. Here we must consider what is meant by the “normal intraocular pressure”.
