The temporal visuogram in ocular hypertension and its progression to glaucoma.
In a study of progression to glaucoma in ocular hypertensive eyes followed for at least 4 years, temporal flicker sensitivity measured at the beginning of the period was evaluated as a predictor of the likelihood of progression. Significantly abnormal temporal visuograms at a 1 criterion predicted progression in 9 of 10 eyes that developed glaucomatous losses. Temporal visuograms for locations in the nasal arcuate area (15 nasal to fixation) showed much greater sensitivity to visual loss than those in the central part of the retina. Comparison with threshold perimetry losses showed that patients within the normal range on the central four points were also within normal range on the temporal visuogram. Peripheral flicker testing was more sensitive than threshold perimetry to losses in the nasal arcuate area in glaucoma patients.
