Macular Visual Fields

AMA Arch Ophthalmol. 1959;62(2):287-294. doi:10.1001/archopht.1959.04220020113017

I. Introduction  The clinician commonly evaluates the macula by examination with various optical instruments and by testing visual acuity. We are all aware of the frequent inconsistencies between visual acuity and the objective information obtained by careful fundus examination. Even when visual fields at a 1-meter distance have been performed meticulously, central or paracentral defects may not be detected. Thus there have been limitations on the value of perimetry as a sensitive test of macular function.A technique for the careful exploration and mapping of macular defects is described in this report. An increase in the distance of the patient from the screen has yielded a corresponding increase in the area covered by the projection of the macula. Thus small defects in the foveal or macular regions can be localized and mapped in detail. In the same way changes in the intensity of the defect can be detected and analyzed.
