A worldwide survey of active duty military optometrists (Air Force, Army and Navy) was conducted in the spring of 1987. The survey response rate was 79%. Statistically significant differences (alpha = 0.01) in their roles, activities and attitudes are presented and discussed. Significant interservice differences were found in: types of duties, profession/status of immediate supervisors, work assignments, frequency and types of patient encounters, awareness of therapeutic drug policies, access to specific clinical instruments, and frequency of routine clinical tests. Attitude and opinion tabulations suggest an overall satisfaction with professional experiences and interprofessional working relationships. However, there was a common perception that optometrists did not receive appropriate promotional consideration or career opportunities within this multidisciplinary setting. Implications of survey results for non-military multidisciplinary health care institutions are also discussed.
