A new classification of glaucoma including focal glaucoma.

This report suggests a new method of classifying glaucoma based upon the appearance of the optic nerve. One subdivision of this classification, focal glaucoma, is discussed in some detail. As is true for all classifications, the system proposed will not be a permanent one. Nor is it intended to be all inclusive. Its purpose is not to replace the system which at present is based on the mechanism for intraocular pressure elevation, i.e., angle-closure glaucoma, open-angle glaucoma, etc., but rather to provide a means by which various subtypes of glaucoma can be better differentiated.
