The development and present structure of the comprehensive Low Vision Service of the New York Association for the Blind are used as the basis for a full discussion of the operation of such a clinical service, including its positive and negative features. The clinic is administered by a medical director and by an administrator who coordinates the work of a staff consisting of ophthalmologists, optometrists, low vision assistants, volunteers, registrar, and receptionist. A separate Optical Aids Service stocks low vision aids which it sells by prescription to clinics, doctors, and patients within and without the agency. Referrals for special services are made to the other departments of the agency. Also described are the low vision examination itself, follow-up and training services, and the aid loan system.
