Abstract
Circular static perimetry was carried out on preselected points in the Bjerrum area on normal eyes and eyes with ocular hypertension. It was found that in the normal subject there was a decline in sensitivity with age, most particularly marked in the upper field. Eyes with ocular hypertension showed more reduction in sensitivity than normal eyes in the same age group. It is postulated that in ocular hypertension there is premature aging of the field in the Bjerrum area
