Abstract:
A new test chart has been developed as a quick, alternative and supplementary method of perimetric evaluation of the central 25 degrees of the visual field to test for the presence of relative and absolute scotomas as part of a routine eye and neurological examination. The result of a comparison of this test with formal perimetry in 107 patients is described and discussed.
