Supplementary services may be provided by the Commission to any applicant or recipient who is in need of treatment either to prevent blindness or to restore the applicant's or recipient's eyesight whether or not the applicant or recipient is blind if the applicant or recipient is otherwise qualified for assistance under this chapter. The supplementary services may include necessary traveling and other expenses to receive treatment from a hospital, clinic, ophthalmologist or physician skilled in diseases of the eye, designated by the Commission. In cases of total blindness even where the maximum amount of assistance of $60 per month is allowed, the Commission may provide additional sums for medical and nursing care where the income of the recipient from all sources, together with such help as that recipient's family is able to render, is insufficient to provide reasonable subsistence and medical and nursing care compatible with decency and health.
