An investigation of referral patterns of physicians for eye care was conducted in the Primary Care Department of a major medical school in New York City. A review of records of adult patients age 40 and over was conducted to examine referral patterns over a period of a year. Only 12.5% of the patients were referred from the primary care department for eye examinations; in 87.5% of cases, no referral for eye care was made, and no recommendations on eye care were provided to patients. Of the patients with hypertension, 34.8% were referred for eye care. Of those with diabetes, only 8% received referrals for eye examinations. Most patients did not have ophthalmoscopy, glaucoma tests, or any other vision testing. Only 33.3% of patients examined within the primary care department had fundus examinations conducted by the physician. This investigation was helpful in providing feedback to physicians in the department on their referral patterns, and in raising the consciousness of health care professionals about the importance of routine eye care.
