Measuring trends in optometric practice: a study in Oregon.

BACKGROUND

Considerable change has occurred in the United States, over the past several years, broadening the scope of optometry to include the treatment of ocular disease. This change has received a great deal of "press", however little has been done to measure actual trends occurring in the practice of optometry. A study was undertaken in 1991 to establish an accurate profile of optometric practice in the state of Oregon including trends over the past five years and those projected into the next five years.

METHODS

A sampling of all optometrist (465) in the state was done early in 1991, query being made as to five years back (1986) and five years ahead (1996) relative to various practice characteristics. The return rate was 51%.

RESULTS

It was found that general examinations, spectacles, and contact lenses are services offered by, essentially, every office. However, there is considerable variation, office-to-office, on all other services. Projections into the next five years forecast increased services in contact lenses, vision therapy, and the management/treatment of ocular disease. As to technology, trends indicate greater use of auto-refractors, auto-keratometers, automated visual fields, and binocular indirect opthalmoscopy.

CONCLUSIONS

Optometrists in Oregon are optimistic on the projected growth of particular services. While this outlook seems to be based on an existing patient base in most areas of care, it appears to assume that projected treatment privileges will attract a new and expanded base of patients relative to ocular disease.
