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 .
