What are microperimeters used for?

• A. Tests Peripheral Fields
• B. Tests Macular Function
• C. Tests Color Vision
• D. Measures Intraocular Pressure

Answer: (B)

Microperimeters are used to assess how well the central retina—the macula—functions. They present light stimuli to precise points on the macula while tracking the eye’s fixation, so you get a map of retinal sensitivity that corresponds exactly to where those points sit on the retina. This is especially valuable for macular diseases, where central vision is affected, because you can track changes in macular sensitivity over time and see how fixation stability relates to structure seen on the retina. It’s different from tests of peripheral fields, which evaluate sensitivity across a wider area of the retina, and it isn’t a color vision test or a tool for measuring intraocular pressure.
