Is Glaucoma an Optic Neuropathy?
Journal Title: International Journal of Ophthalmology & Eye Science (IJOES) - Year 2016, Vol 0, Issue 4
Abstract
Glaucoma is defined as an optic neuropathy implying that nerve fibers are being atrophied in glaucoma. However, there are many distinctive morphological and histological features between the glaucomatous disc and nonglaucomatous optic atrophies. In glaucoma, there is always the orderly loss of nerve fibers starting with the peripheral fibers and ending with the central. In contrast, the nerve fibers loss in non-glaucomatous optic atrophies is always non-orderly. Furthermore, in glaucomatous discs there is development of disc excavation whereas no such excavation occurs in nonglaucomatous optic atrophies. This article will discuss the various distinctive features between glaucomatous disc and nonglaucomatous optic atrophies and conclude that the nerve fibers are being severed, not atrophied in glaucoma. Therefore, glaucoma may not be an optic neuropathy but an optic axotomy.
