Purpose: To compare the Standard Patient Evaluation of Eye Dryness (SPEED) and the Ocular Surface Disease Index (OSDI) questionnaires, and to further validate the SPEED questionnaire using the OSDI in a nonclinical sample. Methods: This was a cross-sectional study involving 657 undergraduate students aged 18-34 years. Subject selection was by sy...

Purpose: The presence of flanking targets can impair depth discrimination, presumably through lateral interaction or crowding. We characterized the spatial extent of foveal stereo crowding to examine the influence of flanker and reference bar width on depth discrimination thresholds. Methods: Five adults with normal visual and stereo acuity partici...

The purpose of the study was to determine the epidemiology of ocular disorders and visual impairment among junior high school children in the Cape Coast Metropolis, Ghana. A cross-sectional study was conducted among junior high school children from both public and private schools. Participants underwent ophthalmic examination that included visual...

Background In the absence of adequate services, patients have to rely on the few health professionals that they do come into contact with to advise them on their treatment options.
