Assessment of vision in amblyopia.

This paper presents a brief review of clinical methods of assessment of vision in amblyopic infants and children. The problems encountered in this context include attention and motivation of the patient, and reliability and standardisation of method. Various solutions are examined and the relevance of the newer techniques of acuity estimation by preferential looking (PL), visual evoked cortical potentials (VECP) and psychophysical tests of contrast sensitivity is discussed.
