Binocular vision refers to the integration of images in the two eyes for improved visual performance and depth perception. One aspect of binocular vision is the fixation disparity, which is a suboptimal condition in individuals with respect to binocular eye movement control and subsequent neural processing. The objective fixation disparity refers to the vergence angle between the visual axes, w...

would be present when the patient is reading. The test therefore has good ‘face validity’ for identifying binocular vision anomalies which are likely to interfere with the usual reading process. Recent research has shown that the questions the practitioner asks during this test are crucially important. Quite commonly, the patient is just asked whether the Nonius markers (green strips) are lined...

DURING the last few years it has been found that many patients presumed to have normal binocular single vision after optical, orthoptic, and/or surgical treatment, have in fact a small angle of anomaly. From certain points of view this is not of great importance, as such cases are satisfactory cosmetically, and show good visual acuity in each eye with a limited degree of fusion detectable by ce...

PURPOSE To determine the one-year incidence of needle stick and sharp injuries (NSIs and SIs) and their associations with visual function among Iranian nurses. METHODS In this cross-sectional study, 278 nurses working at one hospital were selected through stratified random sampling. After applying the exclusion criteria, the final analysis was performed on the data of 267 nurses. The data of ...
