|Appropriate recently developed techniques are described to evaluate objectively visual acuity and hemianopia in subjects unable or unwilling to cooperate, while both temporal and spatial resolution may be subjectively assessed, resp. foveal flicker fusion frequencies (4F) and coloured contrast sensitivity frequencies (CCSF). A simple and easy to handle equipment for temporal resolution (4F) has recently been developed, as well as a new instrumental approach to CCSF (A.N. and P.V.D.E.). © 1992 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
