A joint organizational statement on vision and therapy for learning disabilities and dyslexia is presented by the American Academy of Pediatrics, the American Academy of Ophthalmology and Otolaryngology, and the American Association of Ophthalmology. (CB)

Results of three factor analyses on the Frostig DTVP subtests indicated that the test measures one general visual perception factor, rather than the five postulated by Frostig. (Author/KW)

Ocular defects of congenital rubella are discussed, and the current status of the development of the rubella vaccine and the immunization program is summarized. (KW)

A discription of teaching activities and seeing distances makes it easier to prescribe correct lenses. (AP)

The author discusses the advantages and made to measure microcomputer programs for the partially sighted student. Several strategies for using the microcomputer in the classroom are suggested. (SW)

The article describes a three-part driving program for low vision persons in which potential trainees are first interviewed for problems which may interfere with success, then trained to recognize objects through a bioptic lens system, and finally trained on road signs and markings. (Author/CL)

The most commonly used chart for testing eye acuity is the Snellen Chart, developed more than 100 years ago. A description is given of the way this chart works, its uses, and its limitations. (JD)

Two experimental reading development courses were conducted for six partially sighted students who read so slowly that they could not complete their study assignments. At the end of each course, the participants' proficiency in reading improved dramatically. (Author)

The author discusses the current status of driving for persons with low vision, both with and without using a bioptic telescope. Licensing criteria, training sequences, and problem areas are considered. (Author/CL)

A fly is buzzing around in the kitchen. You sneak up on it with a flyswatter, but just as you get close to it, it flies away. What makes flies and other insects so good at escaping from danger? The fact that insects have eyesight that can easily detect moving objects is one of the things that help them survive. In this month's Science Shorts,…

A variety of obstacles can prevent persons or individuals with low vision from deriving the greatest possible benefit from the rehabilitation process, including inadequate understanding of their visual impairment, lack of knowledge about available services, and misconceptions about low vision devices. This study explores the use of a…

Evidence suggests that perceptual networks in the ventral visual pathway are necessary for action control when targets are viewed with only one eye, or when the target must be stored in memory. We tested whether memory-linked (i.e., open-loop versus memory-guided actions) and monocular-linked effects (i.e., binocular versus monocular actions) on…

The relationship between luminance (i.e., the photometric intensity of light) and its perception (i.e., sensations of lightness or brightness) has long been a puzzle. In addition to the mystery of why these perceptual qualities do not scale with luminance in any simple way, "illusions" such as simultaneous brightness contrast, Mach bands,…

This article comprises a historical review of the literature pertaining to the representation of the visual field in human primary visual cortex. A brief survey of the anatomy of the visual system is followed by a critical evaluation of the key studies that have informed both the issue of the disproportionate representation of central vision…
