The NIDEK MP-3 is a cutting-edge microperimeter that combines retinal sensitivity testing, high-resolution fundus imaging, and visual rehabilitation. With a wide stimulus range and precise eye-tracking, it accurately measures fixation stability and preferred retinal locus especially useful for patients with central vision loss. Its rehabilitation mode helps train patients to improve visual function, while the MP-3 type S adds scotopic testing for low-light retinal assessment. Automatic tracking and alignment enhance both accuracy and efficiency for consistent follow-ups.
