A report is presented over the ocular fin-dings of 119 pupils attending the Numazu School for the Blind in Shizuoka Prefecture in southeast Japan. Chief findings were:

2. 90.8% of cases were less than 20 years of age.

3. 77.3% of cases had visual acuity of less than 0.1 and 29.4% had less than 0.02.

4.64% of cases were congenitally blind and 79.2% became practically blind before the age of 10.
