It measures how different small areas of the central retina are working, rather than giving one overall average result. It is commonly used in ophthalmology and optometry clinics to evaluate unexplained vision symptoms and to support diagnosis or monitoring of macular and retinal conditions. It is a diagnostic test, not a treatment."}
