| Research Abstract |
The ninth quinquennial survey of students in schools for the visually impaired in Japan took place in 2010. Through a questionnaire, data were collected from 3,375 students in 70 schools for the visually impaired. In the etiology, 51.4% of the students were distributed in prenatal influences, 18.7% in retinopathy of prematurity, 12.7% in undetermined, and 8.1% in general diseases. The rates of students classified with the sites and types of affection were 50.1% in retina, 20.8% in eyeball, and 15.7% in optic nerve, optic pathway, and cortical visual centers. From similar quinquennial survey in special classes for the visually impaired in Japan, data were collected from 241 pupils and 57 students in 155 elementary schools and 48 secondary schools. In the etiology, 55.4% of the students were distributed in prenatal influences, 21.5% in retinopathy of prematurity, and 11.7% in undetermined. The rates of students classified with the sites and types of affection were 41.3% in retina, 26.9% in eyeball, and 10.1% in optic nerve, optic pathway, and cortical visual centers.
