National health and optometry--a survey of public attitudes.

A stratified probability sample of the Houston, Texas population was interviewed to assess public opinion of national health care and public awareness of vision care and its role in a national health care system. Over 80% of the population surveyed are in favor of a national health care bill, with a large percentage of the population favoring inclusion of vision care. Demographic trends are reported as they relate to various questions in the survey, and comparisons are made to a similar questionnaire one year earlier.

Primary health care - the role of optometry.

Optometrists, like all health care providers, should emphasize primary or preventive care. To provide this care optometrists must be aware of the risk factors for major causes of mortality. As an example, the risk profile for a white male age 45 to 49 years is given and discussed. Suggestions for primary vision care and detection of major risk factors by optometrists are also presented.

Applications of catastrophe theory to optometry.

Catastrophe theory, a recently developed area of mathematics, is used to model two aspects of visual behavior. Visual behavior measured in a patient undergoing phorometry and the visual behavior of some patients with anomalous retinal correspondence undergoing the Walraven technique are characterized as catastrophes.

Optometry and optometric practices in Nigeria.

This paper describes the number, distribution, and characteristics of optometric practices in Nigeria and compares them to similar data in the U.S.A. The results indicate more similarities than differences--the latter attributable to the difference in the age of the profession in the two countries.

Optometry in the multidisciplinary health care setting.

A variety of health care delivery settings and models have been established in the 1980s. The multidisciplinary setting encourages comanagement and continuity of care, provides convenient consultation and communication, and is cost effective. It stimulates learning, helps to consolidate management strategies, and results in improved quality of care. Therefore, the patient and the provider both benefit from this environment. In 1978, the problem-oriented record keeping system (PORS) was implemented in the eye care service of a Boston neighborhood multidisciplinary health center. It facilitated learning, established guidelines for peer review, and improved patient care by assisting the eye care service to communicate patient problems to the other health center services effectively. We review the background of urban multidisciplinary health care settings and the PORS, as well as present several cases in which optometrists participated in patient comanagement with other health care specialists to develop a comprehensive management plan. The benefits of the multidisciplinary approach to both patients and providers are discussed.

Use of interferometric visual stimulators in optometry.

Professor Fergus Campbell and colleagues pioneered the use of the interferometric visual stimulator as a tool for separating optical from neural factors which limit spatial vision. The device is now commercially available as a clinical instrument which 'bypasses the optics of the eye' to measure the potential visual acuity of the neural portion of the visual system. However, the clinician needs to be aware of limitations of current instrument designs and recent advances in our understanding of peripheral vision, to correctly interpret patient data gathered with these devices.

Electrophysiological optometry using Scheiner's principle in the pigeon eye.

A new electrophysiological optometer has been developed, based on Scheiner's principle. Using two light-emitting diodes driven in counterphase, and grating stimuli in Maxwellian view, the system has been used to refract the photoreceptor plane of the pigeon eye. When a grating is conjugate with the photoreceptors, the electroretinographic response (e.r.g.) is minimal, and the image is stationary. As defocus is introduced, so image shift occurs, and the e.r.g. rises on each side of the refractive minimum. Two experiments were devised to test whether a derived minimum point is primary, by using gratings of bar width 3, 5 and 7 units, and by using random checkerboard stimuli. Ray tracing was used to compute the lobe width of dioptric profiles for gratings of spatial frequency 1.47, 0.88 and 0.63 cycles/deg. The computed lobe widths agree well with experimentally determined e.r.g. profiles. Examination of the lateral visual field, on the horizon, shows that the pigeon eye is emmetropic, and well corrected for astigmatism.
