Abstract: Macular edema secondary to diabetic retinopathy, retinal vein occlusion, and uveitis can severely affect visual function. Microperimetry that allows precise and efficient assessment of regional retinal sensitivity can assist in objective analysis of the correspondence between microstructural changes of macular edema and the functional decline. As a complement to visual acuity, microperimetry can detect  changes in visual function brought about by new therapies.(Int Rev Ophthalmol, 2021, 45: 216-220)

Key words: macular edema, diabetic retinopathy, retinal vein occlusion, microperimetry
