An image intensifier aid for chronic night blindness.
Working with the Retinitis Pigmentosa Foundation, ITT has designed an image intensifier monocular specifically for application as a prosthetic aid for persons suffering from chronic night blindness as a result of retinal degenerations. A description of the instrument along with the rationale for its major design points is given and its applications illustrated. The first few of these instruments were delivered earlier this year and limited production has been started.
