Recent acquisitions in evaluation of sensorial visual functions

Abstract

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.).

Key Words:

• visual acuity
• hemianopia
• objective evaluation
• foveal flicker fusion frequency
