Microperimetry

Microperimetry, or fundus-tracked perimetry, is a visual field test to assess central retinal function. Current uses of microperimetry have been built on early developments of non-automated fundus-tracked perimetry. These devices have subsequently improved with the innovation of scanning laser ophthalmoscopy. Microperimetry allows for the measurement of fixation stability and topographic characterization of visual function, enabling a correlation between retinal structure and visual function. Using microperimetry, the sensitivity threshold of any point of the retina can be matched with its clinical appearance in real-time. This method can therefore provide insights into disease progression and severity, particularly in conditions that affect the retina. This chapter comprehensively reviews the history, technology, techniques, and clinical application of microperimetry.
