A report is given over the outcome of mass examination of 1,253 visually impaired persons conducted by the author for the past 3 years in Shizuoka Prefecture, an agricultu-ral area about in the middle of Japan Main-land.

1. Sixty per cent of all examined eyes were totally or practically blind with visual acuity of less than 0.02.

2. Eye disorders of developmental nature played the commonest cause for the visual impairment amounting to 25.6% of all eyes examined.

3. There was a striking frequency of pi-gment degeneration of the retina at 33.6% of all congenital eye disorders.
