This article considers the visual rehabilitation of patients recovering from traumatic brain injuries. Characteristics, symptoms, and associated neuromotor difficulties of posttrauma vision syndrome are listed, as are common posture and gait adaptations. A neuro-optometric rehabilitative and orientation/mobility evaluation is recommended, as is…

A fly-only group (N=16) of Navy replacement pilots undergoing fleet readiness training in the SH-3 helicopter was compared with groups pre-trained on Device 2F64C with: (1) visual only (N=13); (2) no visual/no motion (N=14); and (3) one visual plus motion group (N=19). Groups were compared for their SH-3 helicopter performance in the transition…

As one of a series commissioned by the National Reading Center to help inform all citizens about reading issues and to promote national functional literacy, this brochure is designed to acquaint readers with different forms of visual impairment, and describes their symptoms for easy recognition. Visual difficulties are classified into two major…

The functional architecture of the primary visual cortex has been explored by monitoring the responses of individual brain cells to visual stimuli. A combination of anatomical and physiological techniques reveals groups of functionally related cells, juxtaposed and superimposed, in a sometimes complex, but presumably efficient, structure. (BB)

The study examined whether individual levels of optimal illumination could be reliably determined for visually impaired adults and whether the level identified in the assessment had validity in relation to a practical reading task. The assessment procedure was found to be reliable and valid and reading performance improved. (Author/DB)

An ophthalmologist reviews the clinical features of dyslexia, gives guidelines for recognition and referral, discusses controversies regarding the management of learning disorders, and stresses the need for a multidisciplinary approach. Also included are the ophthalmologist's answers to practitioner questions. (Author/DB)

Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Reasons for the relative lack of literature dealing with spatial concepts of low-vision children are suggested, and two assumptions are seen as invalid: (1) that knowledge of spatial concepts is not important for persons with low vision and (2) that children with low vision have adequate knowledge of spatial concepts.

The author traces the history of optometric vision training and its influences on academic performance and presents his views on the current controversy over the value of vision training for students with learning disabilities. He concludes with a list of approximately 50 references on the topic. (CL)

Six common visual dysfunctions are briefly explained and their relationships to reading noted: (1) ametropia, refractive error; (2) inaccurate saccades, the small jumping eye movements used in reading; (3) inefficient binocularity/fusion; (4) insufficient convergence/divergence; (5) heterophoria, imbalance in extra-ocular muscles; and (6)…

Microscope materials in biology and general science adapted for audio-tutorial learning were successfully used by 75 low vision mainstreamed students in grades 5-12. (CL)

Reading speed of 72 partially sighted adults was examined under conditions of simulated and real visual impairment. Visually impaired Ss with normal visual fields and defective central or peripheral fields performed similarly to normally sighted Ss participating in simulated visual impairment. It is concluded that reading speed depends on acuity.…

The article discusses the design, application, and clinical uses of press-on optics which are descirbed as 1 millimeter thick, flexible lenses or prisms that may be produced in virtually any desired plus or minus dioptric power as ophthalmic lenses, or in any range of usable prism diopter power.
