Apart from the glaucomatous changes in the optic nerve head, the other two factors in isolation lack diagnostic sensitivity. In fact, studies have shown that careful evaluation of the optic nerve head has high specificity and that an ...Read More

Glaucoma, by definition, is chronic, progressive optic neuropathy.[1-3] Structural damage to the optic nerve head (ONH) is a characteristic feature of glaucoma and precedes visual field loss in most cases. Para-papillary changes may also be observed in eyes with glaucoma. The mere presence of raised intraocular pressure is not glaucoma. Hence, the optic disc evaluation is the first and most import...Read More
