Variability of visual field measurements in normal subjects and patients with retinitis pigmentosa
D. F. Ross, G. A. Fishman, L. D. Gilbert and R. J. Anderson
Twenty-one normal subjects and 26 patients with retinitis pigmentosa (RP)
underwent Goldmann perimetry to ascertain both interexaminer and
intraexaminer variability. The data are of value for monitoring the natural
disease progression in patients with RP and for defining the tolerance
limits of field variability in normal subjects.
