Hyperacuity test to evaluate vision through dense cataracts; research preliminary to a clinical study. IV. Data on patients with macular degeneration and minimal media disorders obtained with and without a pseudo-nuclear cataract 6/60 (20/200) at the Aravind Eye Hospital, Madurai, India.
Using a recently discussed three-point Vernier alignment test, data were obtained on patients with macular dysfunctions with and without a pseudo-nuclear cataract 6/60 (20/200) at the Aravind (Free) Eye Hospital, Madurai, India. The pseudo-cataract caused measurably and predictably reduced Vernier alignment thresholds, and necessary modifications deemed to be necessary in the protocol for later study are defined.
