When intraocular pressure lowering does not halt visual field progression in an eye which has classic features of glaucoma (glaucoma cupping, retinal nerve fiber loss and normal visual acuity and colour vision), a diagnosis of compressive optic neuropathy should be considered. While disc pallor is recognised to be a sign of potential ominous disease, it should be appreciated that in the early stages of compressive optic neuropathy, the disc may maintain its normal colour
The Science behind the Tip Axonal loss decreases the volume of the disc, and if loss is concentrated in one area without significant gliosis,...

While adherence to therapy is undoubtedly important, at least equally important is the patient’s adherence to a prescribed follow up schedule. Therapies can fail over time and missing follow up appointments can be particularly hazardous for fast progressors-practitioners should stress the importance of good follow up
