Global ophthalmic, optometric, and lens edging equipment manufacturer NIDEK CO., LTD. has announced this week its launch of the feedback exam for visual rehabilitation and scotopic microperimetry for the MP-3 Microperimeter.
The MP-3 measures local retinal sensitivity for functional assessment of the retina with a maximum stimulus luminance of 10,000 asb. The results can be displayed over a color fundus image, correlating retinal anatomy to retinal function. Using the displayed measurement results, the feedback exam function provides visual rehabilitation training for low vision patients who have lost foveal fixation to relocate their preferred retinal locus to a different region, called the trained retinal locus (TRL). The TRL is predetermined by a physician and fixation rehabilitation allows the patient better functional vision (i.e. reading speed) due to increased fixation stability and visual outcomes. The feedback exam is released as a standard function in the MP-3.
The MP-3 type S, which provides scotopic microperimetry, is also being released concurrently. Scotopic microperimetry is used to assess the changes in rod sensitivity of degenerative retinal diseases including age-related macular degeneration and some forms of retinitis pigmentosa. This modality can be used in clinical trials of new therapeutics for retinal diseases that impair rod function. The MP-3 type S is currently available only in countries with CE marking.
“With the introduction of these new functions for microperimetry, we are providing methods to maximize visual performance among low vision patients for a better quality of life.” says Motoki Ozawa, President and CEO of NIDEK CO., LTD. “The incorporation of these new functions in the MP-3 will allow low vision care providers to offer enhanced options for low vision patients.”
