Studies of Eye Complaints induced by VDT

Sixty two outpatients who visited the eye department of the Ehime Labour Hospital, suffering from visual display terminals (VDT) operation-related diseases were classified into 4 catepories. Category 1 consists of mainly so called middle management personnal aged around 50 years old. Category 2 consists of the female operators of VDT in their early twenties. Category 3 consists of workers of young age. Re-ossurence of central retinitis, glaucoma, or Keratoconjunctivitis sicca is thought to be due to the engagement of VDT operation. Category 4 consists of a group patients suffering from cataract induced by microwaves emitted from prolonged and continued usage of out-of-dated VDT machines, as suggested by Zaret. It is expected to understand the concept of health care guidance even in various terminal divisions of a company, though the type and content of work are different in the various departments.
