Differences in visual-ocular function, particularly optokinetic nystagmus (OKN), were compared with 40 learning disabled and 40 normal children (8-12 years-old). No significant differences were found between groups on the variables tested (refixation saccades, smooth ocular pursuit, spontaneous nystagmus, gaze nystagmus, and OKN). (Author/DB)

Describes work by the American Academy of Ophthalmology (AAO) to expand the standardized vocabulary, Systematized Nomenclature of Medicine (SNOMED), to accommodate a definitive ophthalmic standardized vocabulary. Mapped a practice-based clinical ophthalmic vocabulary to SNOMED and other vocabularies in the Metathesaurus of the Unified Medical…

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)

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)

The author points out the need for early screening for ophthalmologic disorders and reviews symptoms of various eye disorders. Among the types of eye pathology considered are retinoblastoma, retrolental fibroplasia, congenital glaucoma, congenital cataracts, congenital strabismus, chlamydia oculogenitalis, orbital cellulitis, and eye injuries.…

The need to counsel patients with genetic ophthalmological problems is stressed in the article. Assessment of autosomal dominance or autosomal recessitivity in an individual is explained and sex-linked heredity is traced. Practical examples of genetic abnormalities, such as pigmentary retinopathy and chorodineremia, are discussed. (PHR)

It has recently been shown that perceived motion, in the absence of any appropriate retinal motion, is a sufficient stimulus to generate smooth pursuit eye motions. However, three experiments show that perceived motion is not necessary for pursuit, but that retinal motion always governs pursuit. (BB)

Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness. The researchers report that nanophthalmos, Greek for "dwarf eye," is a rare, potentially blinding disorder caused by an alteration in a gene called MFRP that helps control eye growth and…

As the proportion of older adults in the U.S. population grows, the prevalence of visual impairment related to cataracts, glaucoma, macular degeneration, and diabetic retinopathy will increase as well. Individuals who are visually impaired require various degrees of support and assistance in their daily activities. This assistance is frequently…

In 73 children (6-13 years old) with reading difficulty, ophthalmological evaluation showed that 18 had overt refractive errors, 18 dyslexia and no ocular anomalies, and 37 impaired fusional amplitudes, 24 of whom were dyslexic. In all Ss with poor fusional amplitudes the reading mechanism could be improved with orthoptic exercises. (Author/CL)
