RESUMO
A step-by-step case report describes the rehabilitation program for visual dysfunction of a 52-year-old woman, beginning 2 years post-trauma. Methods to ameliorate such symptoms as diplopia, ocular discomfort, dry eye, inefficient saccadic movement, spasms of accommodation, poor reading comprehension and very limited stamina for near visual tasks are presented. Specific procedures are discussed and results are described and tabulated.
RESUMO
Forty-eight binocular, non-presbyopic optometry students, unfamiliar with the purposes of the study, were provided with several matched passages of material to read in a given time sequence. Multiple choice questions were to be answered at the completion of each reading passage. These were administered in a randomly counterbalanced presentation (a b b a) utilizing either base-in prism or plano lenses in spectacle form. The results of this experiment showed a statistically significant lower comprehension rate with the base-in prism lenses in place as evidenced by fewer correct answers to the questions following the reading passages. This effect was found to be greater for the longer reading passages followed by a greater number of questions to be answered.

Two patients with visual problems and reading difficulties originally unable to suppress alpha have been shown to demonstrate alpha rhythm attenuation during the course of and after a program of visual training with simultaneous improvement in reading performance. No direct training of alpha attenuation was engaged in. No other therapy directed toward solution of the patients reading or behavior problems was attempted during the course of visual training. It is concluded that the change in alpha activation and the improvement in reading were both brought about by the combined visual therapy and reading glasses. Further research concerning the number and proportion in the population of learning disabled who respond similarly to the cited cases is presently being undertaken by the author.

A 22-year-old patient having a history of congenital strabismus with surgery at age 6 and again at age 14 suffered from a limitation of dextroversion following 2 surgical procedures with diplopia initially experienced beyond 18 degrees. Ten sessions of treatment by traditional visual training methods and biofeedback reinforcement were compared in extending the deficient range of dextroversion. Biofeedback was found to be significantly better than conventional approaches in this treatment.
