We compared the automated visual field test results of 24 patients with normal-tension glaucoma and 24 patients with high-tension glaucoma who were closely matched for the amount of visual field loss to determine any differences in the characteristic

Prostate cancer is the most common cancer diagnosed in American men. The need to find effective means of preventing this disease is clear. Vitamin A and its analogues (retinoids) act as transcriptional regulators within the nucleus and have been test

We measured the electroretinogram to determine whether ocular toxicity exists in men taking oral fenretinide, 100 mg daily, for prevention of adenocarcinoma of the prostate. Male subjects at an increased risk for prostate cancer were recruited as vol

Pattern electroretrinography (PERG) was performed in 33 patients with chronic open-angle glaucoma (COAG), 18 ocular hypertensive (OH) patients, and 24 normal subjects. COAG patients exhibited significantly lower PERG amplitudes than did normal subjec

It is well known that alteration in color vision may precede other changes of visual function in glaucoma. Unilateral glaucoma patients in whom one eye is diagnosed as having primary open angle glaucoma and the fellow eye is diagnosed as normal may a

The variation of the directional sensitivity of Stiles' (1953) π 1 (μ) mechanism was measured throughout the spectrum on one deuteranope. For wavelengths greater than about 550 nm, the directional properties measured for π 1 (μ) are nearly identi

The intensity of a monochromatic light required just to detect 30 Hz flicker as the point of entry of the light was changed in 0.5 mm steps across the eye's entrance pupil and measured throughout the spectrum on 4 protanopes and 5 deuteranopes. In ge

The density of human rhodopsin in the rods has been estimated psychophysically by following the change in the relative quantum sensitivity for rod vision at two wavelengths (one near the peak, the other far off on the long wave tail of the action spe

Patients with early background diabetic retinopathy and good visual acuity may have normal results on standard methods of measuring color vision. Measurement of individual spectral sensitivity functions shows a moderate decrease in sensitivity of the

Blue cone monochromacy is a rare X-linked disorder of color vision characterized by the absence of both red and green cone sensitivities. In 12 of 12 families carrying this trait, alterations are observed in the red and green visual pigment gene clus
