Abstract:
When macular diseases involves the fovea, patients' central vision is significantly reduced. A central dark spot appears in the visual field, and their visual function indicators, such as reading speed and fixation stability, are significantly impaired, which seriously affects the patients' quality of life. The human body's response to the damage of the fovea region is a spontaneous adaptation strategy adopted by the brain. The brain will select the paracentral region as the pseudo fovea to serve as the fixation site of the eye, however, the development of patient's own residual vision is not maximized by this adaptation behavior. In recent years, through continuous research, it has been discovered that the automatic eye position recognition and automatic eye tracking system in the microperimeter can accurately detect specific retinal sites, combined with the biofeedback training mode, and can combine fundus examination with biofeedback training. It can help patients with age-related macular degeneration, pathological myopia macular degeneration, Stargardt's disease, macular hole and other macular diseases to choose the best retinal site as an eye movement benchmark, maximize the patient's residual vision and improve the patient's visual function.
