Objectives
Narrative objectives1
The retinal degenerations reduce visual acuity because visual acuity has consisted on the high cone density at the fovea. According to World Health Organization, the blindness and low vision ratio in Japan are 0.14% and 0.39% respectively.
The prognosis of retinal degenerations depends on the stage. Therefore, establishing a test method, which detect the retinal degeneration in early stage, expect to reduce the blindness and low vision ratio. Also, that leads to increasing the quality of life in patients with retinal degeneration.
The goal of our study is to establish the new detecting test with the retinal degenerations, which has high detection capability compared with the conventional method, by combining the photobleaching and the adaptive optics scanning laser ophthalmoscopy.
