Abstract
After simply describing the basic principles of the CCTV and its uses in low vision rehabilitation, the author provides a general critique of the system as it is currently being marketed. The unsolved problems include poorly designed and awkwardly placed controls, insufficient stability and flatness of the material to be viewed, the requirement for a high degree of manual dexterity, insufficient servicing capability, lack of provision for adequate training of users, residual or latent image, and high cost. It is concluded that the present generation of devices is insufficient for meeting the needs of low vision patients and that those manufacturers who best solve these problems will be the ones who will survive.
