NEW ORLEANS — A new fundus camera provides ophthalmologists with an image of peripheral vision that accounts for eye movement during testing, according to a speaker here.
David R. Chow, MD, described the features of the MP-1 Microperimeter (Nidek), which combines digital fundus imaging and computerized perimetry at the American Academy of Ophthalmology meeting.
"One of the greatest strengths of the MP-1 is its ability to perform wide eye fixation tracking, so the pictures of the patient's fundus are imaged by an infrared camera and, as the patients' eye and retina move, the camera alters or adjusts for this 25 times per second," Dr. Chow said.
The camera determines the fixation of a patient and to plot fixation as a function of time.
The MP-1 features multiple modes including a training mode, fixation testing, static microperimetry, peripapillary examination, kinetic microperimetry and feedback examination. In all of the modes, physicians can perform progression analysis, as patients are tested at the same points during subsequent exams.
