The disability percentage recorded by the board was compared with the current classification, in order to determine the extent and type of disparity, if any. Data were handled in accordance with the ethical standards of the Helsinki Declaration of 1975, as revised in 2000.

Data relating to vision in both eyes and the disability percentage accorded by the disability board was retrieved and entered into an MS Excel worksheet.
