Visual field assessment is a key part of optometry and ophthalmology practice. However, in people with non-central or unstable fixation, it is not possible to relate defects on a visual field map to a specific retinal location. Microperimetry (or fundus related perimetry) is a technique that images the retina during visual field testing, enabling a correlation to be made between visual function and retinal structure. In this article, the history of fundus related perimetry is reviewed. Three modern microperimeters (MP-1, OCT/SLO and MAIA) are described and their relative merits identified. Finally, the uses of microperimetry in optometric practice are discussed.
