How is early glaucoma defined?
Early glaucoma is defined differently by different specialists. I think of early glaucoma as that which is discovered before definite changes are seen on perimetry [in the visual field test]. This is most easily picked up by noticing an early, slight change in the optic nerve or retinal nerve fiber layer. Previous photos, drawings, HRTs, GDXs, or OCTs are usually needed to be sure change has occurred. Dr.
