健康成人に対する視野異常スクリーニング

Screening of visual field defect among healthy adults. A preliminary trial of population survey of ocular disease

　視力良好な15〜64歳の成人1,811名を対象に視野検査を行ったところ21例（1.2％）に視野異常を検出した。21例中9例は頭蓋内疾患によるもので，また21例中11例は眼底にも異常を認めなかった。

　視野検査に要した時間は1人につき2〜3分であった。

　視野検査を眼科スクリーニング検査として行うことは予防医学上，特に頭蓋内疾患の早期発見のために有用であると思われた。

Visual fields were examined using a static campi-meter (Takada Co. Japan) in 1,811 healthy adults, for the purpose of screening of the visual field defect in healthy populations. The age of the subjects studied varied from 15 to 64 years and averaged 28 years.

Field defects were detected in 21 subjects by the present screening. Diagnostic results after further examinations were as follows; 9 intracranial lesions, 6 retinal lesions, 4 glaucomas and 2 unknown cases.Of the 9 cases of intracranial lesion, one was A-V malformation and two were suspected cases of aneurysm.
