Perimetry and fundus imaging combined in single instrument
Ophthalmology Times March 1, 2003 
Padua, Italy-The MP-1 MicroPerimeter (Nidek Technologies) combines fundus perimetry and fundus imaging in one unit. The instrument enables the structures of the macula and retina to be observed by infrared light, and images are displayed in real time on a monitor. Edoardo Midena, MD, a retinal specialist, has been using the MP-1 device extensively on patients with various retinal pathologies and has been impressed with its capabilities. For Dr. Midena, the data he gathers from this instrument provide him with the "patient's point of view," which he considers to be of ultimate importance for determining potential treatments and for measuring the success of treatments. The MP-1 projects stimuli onto the retina, particularly the macula, and allows the clinician to see in real time the site of projection.This allows the threshold of the retina to be analyzed in normal or pathologic conditions. At the same time, the patient's fixation and the movement of the fixation can be determined.
"This is important in standard computerized perimetry, particularly in patients with low vision, since the location of the scotoma cannot be determined because fixation cannot be checked.The map that is obtained with computerized perimetry may not be the reality for the patient. The MP-1 represents an improvement over scanning laser ophthalmoscope (SLO) microperimetry because it is conceived just for the clinician." With the Nidek MP-1 MicroPerimeter, fixation and retinal sensitivity data are superimposed on a color fundus photograph. Examination time is 4 to 5 minutes. (Photo courtesy of Nidek)
