To provide a bank of normal perimetric data, we tested the central and peripheral visual fields of 102 novice normal subjects using the Humphrey automated perimeter. All eyes used for visual field testing were first carefully examined to be sure that they were, indeed, normal. We calculated population means and standard deviations of each test location and for each decade for age. Average differential light sensitivity decreased with advancing age: ––0.5 dB/decade at fixation, ––0.6 dB/decade in the central (30–2) field, and ––06. dB/decade in the peripheral (30/60–2) field. However, neither the slope nor the shape of the hill of vision changed with aging. Short-term fluctuation was not constant throughout the visual field, but instead was greater in the periphery than the center.

Retrospectively reviewing 4,966 patients with rhegmatogenous retinal detachments, we identified 21 patients with foveal split detachments who had no coexisting macular disease and who had been followed at least 6 months postoperatively. All detached retinas were anatomically reattached with one operation. The average preoperative and postoperative visual acuity was 20/50. Because eyes with foveal split detachments have a good visual prognosis when the retinas are anatomically reattached, we recommend that they be treated urgently, as if they had a maculaspared detachment.
