Perimetry is an important diagnostic tool to identify and measure the extent of defects in the visual field. It helps in diagnosing glaucoma and assessing the progression of glaucoma.[1] This article discusses the process of perimetry and the interpretation of the visual field printouts (Humphrey visual field Analyzer). The history of visual field analysis dates back . They also guide treatment for glaucoma as well as retinal disease, like age-related macular degeneration (AMD) and diabetic eye disease. Optical coherence tomography angiography (OCTA) takes pictures of the blood vessels in and under the retina. OCTA is like fluorescein angiography.
