The education and role of ocularists present and future.

The present and future role of ocularists will depend primarily on the quality of educational and evaluation processes within the field; and secondarily, on adequate education outside the field concerning the unique services ocularists provide. The evolution of this field has followed the paradigm that has characterized specialization within medicine. This begins with the development of special expertise in an area and progresses to the fourth stage of external recognition and acceptance of the status of certification. Ocularists are now embarking on this fourth stage, but have considerable challenges to face before this stage is realized. Between ocularists and ophthalmologists there is a need for a genuine alliance in education as well as in health care delivery. This can be fostered best through communication, collaboration, and cooperation. Collaborative experiences during education would promote continuity in learning and cooperative relationships which would facilitate a smooth transition from training into practice relationships.

Estimates of genetic correlations among clinical measures of the eye.

In a quantitative genetic investigation of seven clinical tests, five pairs were significantly correlated: (1) cover test measures and corneal power, (2) corneal power and divergence recovery points, (3) convergence and divergence recovery points, (4) divergence break and recovery points, and (5) convergence break and recovery points. Common genes may account entirely for the gene influence on cover test measure; thus, parents who are above the population mean for corneal power will have offspring with a tendency toward an exodeviation (phoria). The two convergence amplitudes may depend on the same gene differences, whereas the two divergence amplitudes only partly reflect a common function, suggesting that they may be indexing somewhat different underlying physiologic mechanisms.

A regional course to update the practicing specialist.

Four medical centers collaborated in the development of a course in ophthalmology to present new information and skills to the practicing specialist who is not associated with a medical center. The course is presented in 8 two-day sessions, scheduled Friday and Saturday, four times a year, on a two-year cycle. Thus, the participant loses only four days a year from his practice. This course differs from most of the postgraduate courses currently being offered in that it is designed to update basic specialty knowledge and skills systematically to improve health care delivery.

Ophthalmology in medical student education: philosophy, content, and process.

The level of competency in the diagnosis and treatment of common and emergency disorders needed by nonophthalmologists is assessed and then translated into explicit objectives that specify the levels of mastery to be learned. Effective and efficient methods and materials to achieve those objectives are developed; these, together with more efficient and effective use of instructors, have now been utilized in many different schools and curricular structures, with strong student acceptance.

Surgical correction of superior sulcus deformity occurring after enucleation.

A prefabricated, sculptured, subperiosteal orbital floor implant was used in six cases of cosmetically unacceptable deep superior eyelid sulcus that occurred after enucleation. The implant provided anterior and superior displacement of orbital contents. Surgical placement was similar to the approach for implant placement in orbital floor fracture and provided satisfactory cosmetic and functional results.

Genetic analysis of vergence measures in populations with varying incidences of strabismus.

Genetic parameters were contrasted for vergence amplitudes within three populations--esotropic, exotropic, and randomly selected populations-who differed in their incidence of subtypes of strabismus. In general, heritabilities for convergence exceeded those for divergence, and heritabilities for recovery points exceeded those for break points. Heritability estimates for diveregence amplitudes were significantly different for the random and esotropia populations, while convergence heritability estimates for these groups were similar. Thus, gene differences influencing divergence ability contributed to genetic variance for strabismus.

Genetic analysis of cover test measures and AC/A ratio in human populations with varying incidences of strabismus.

The genetic analyses of indices relating to distance alignment and accommodative convergence are presented. This approach is important in understanding the contribution of genetic factors to observed individual differences for these measures. Abnormalities of either of these two components results in a tendency towards either a convergent or divergent position of the eyes (relative to the position of fusional demand) and thus places an additional load or strain on the other components of the binocular mechanism which must compensate for this potential disruption. If compensation is inadequate to maintain alignment of the eyes, a manifest deviation will result. Consequently, an understanding of the aetiology of such factors underlies an understanding of the aetiology of nonparalytic strabismus. The three populations displayed different tendencies in the cover test measure. The average tendency for each of the populations was consistent with the type of deviation common to all propositi of families within each of the respective populations. The heritability of this character was similar in the three populations and was dependent on the contribution of the female parent only, but to a substantial degree (h2 = 0-42 +/- 0-12). The nature of the sex difference is at present open to speculation. The population means within generations were similar for the gradient measure of AC/A ratio. The heritability of this character (0-38 +/- 0-09) suggests that the genetic component is of substantial importance underlying individual differences for AC/A ratio.

Genetic analysis of indices of corneal power and corneal astigmatism in human populations with varying incidences of strabismus.

Heritability estimates for corneal power were found to be high and similar for two populations which differed in their incidence of esotropia. This similarity suggest (1) that genetic differences for corneal power do not contribute to the difference in heritability for spherical refractive error reported for these populations and (2) that this character is not a critical variable contributing to the pathophysiology of esotropia. Heritability estimates for corneal astigmatism were, in most cases, rather low. The pattern of population and sex differences among heritability estimates was consistent with those previously reported for cylindrical refractive error. These population differences in heritability suggest that they contribute to population differences found for cylindrical refractive error.
