Glaucoma screening sponsored by the Sight Conservation Research Center, a volunteer agency, has proved to be rewarding. Much of its success depends on its association with the Santa Clara County Health Department. The follow-up program would be very difficult without the public health nurses and personnel provided. More than 30,000 persons have been screened, with a case-finding percentage of 1.33% for positive glaucoma and 2.32% for borderline glaucoma; only about 1% of the referrals have been closed without diagnosis. When the success of the glaucoma screening program became apparent, other tests were added, including x-ray film of the chest, respiratory-function tests, blood pressure, blood glucose, hematocrit, cholesterol, and uric acid. The number of borderline glaucoma patients that have become positive (58) is firm justification of the long-term follow-up program.
