WebGlaucoma is generally described as a loss of retinal ganglion cell axons. This loss is routinely diagnosed by the presence of thinning of the optic nerve neuroretinal rim, peripapillary retinal nerve fiber layer (RNFL), and/or inner layers of the macula.

What is a 24 2 visual field? The visual field (VF) pattern most widely used to detect glaucomatous damage, the 24-2 test pattern, does not adequately test the macular region, as the 6 grid of the 24-2 pattern has only four points within 8.
