Contrast sensitivity deficits in subjects with glaucoma-like discs using an oscilloscope-based method.
The central visual function of 20 subjects with glaucoma-like discs, normal intraocular pressures and normal visual fields and 20 age-matched normal subjects was assessed by measuring contrast sensitivity using an oscilloscope technique. The subjects with glaucoma-like discs exhibited a significant reduction in contrast sensitivity compared to the age-matched normal; these differences were greatest at spatial frequencies of 2 and 4 cdeg-1.
