Mikroperimetrie

Core Messages: Age related macular degeneration causis visual functions changes mainly quantified by visual acuity. Exact quantification of fundus-related retinal sensitivity and retinal fixation caracteristics are essential in AMD eyes. These parameters can not be obtained by measuring visual acuity. Microperimetry (fundus perimetry) allows a precise quantification of retinal sensitivity and fixation in macular disorders, and it allows accurate and reproducible follow-up examination. In both early and advanced AMD, microperumetry shows that retinal sensitivity changes are related to macular alterations detected by advanced macular imaging techniques (OCT, fundus autofluorescence). Moreover, microperimetry may detect macular derangement more precociously than other retinal imaging tecniques. Microperimetry is complementary to imaging in the diagnosis and follow-up of treated and untreated, providing more visual function information compared to visual acuity.
