“…Eyes without formed vision were classified into one of four low-vision categories, which were assigned decimal equivalents as follows: counting fingers ¼ 0.00500; hand motion ¼ 0.00250; light perception ¼ 0.00125; and no light perception ¼ 0.00100. 18 The logarithm of reciprocal decimal VA was used to approximate the logarithm of minimal angle of resolution (log MAR). All statistical analyses were conducted using SPSS software (Standard Windows version 15.0, SPSS, Chicago, IL, USA).…”
