Abstract

Ocular hypertension (OHT), or elevated pressure in the ocular media, is a condition that is closely monitored by the ophthalmologist. The reason is that it can lead to irreversible visual field loss at which time the diagnosis is changed from OHT to glaucoma. Field losses that are observed are usually attributed to ischemia (1) and mechanical pressure (2, 3) at the optic disk. More recently, however, Regan and his colleagues have suggested that there may also be ganglion cell dendritic pathology associated with OHT that is accompanied by visual loss to which conventional perimetry is not sensitive (4,5). In particular, the dendritic pathology may affect temporal (i.e. , flicker) more than spatial aspects of vision.
