A person with low vision has some useful sight. However, low vision usually interferes with the performance of daily activities such as reading or driving. Because low vision cannot be improved by mere traditional methods (i.e., the use of eyeglasses, contact lenses, etc), persons with low vision often rely on the use of a number of different instruments, called low vision devices, and tailored...

INTRODUCTION Low vision is an important public health problem. OBJECTIVE To study the profile of low vision patients in a hospital of Nepal. MATERIALS AND METHODS Information related to the patients' profile, visual status, ocular disease and, low vision devices prescribed were obtained retrospectively from the records of 1,860 visually- impaired patients, regardless of the cause, presentin...

PURPOSE The contrast sensitivity function (CSF) provides a detailed description of an individual's spatial-pattern detection capability. We tested the hypothesis that the CSFs of people with low vision differ from a "normal" CSF only in their horizontal and vertical positions along the spatial frequency (SF) and contrast sensitivity (CS) axes. METHODS Contrast sensitivity for detecting horizo...

It is well known that object recognition requires spatial frequencies exceeding some critical cutoff value. People with central scotomas who rely on peripheral vision have substantial difficulty with reading and face recognition. Deficiencies of pattern recognition in peripheral vision, might result in higher cutoff requirements, and may contribute to the functional problems of people with cent...

• All children who have undergone bilateral cataract operations, both those with pseudophakia and those with aphakia • People with diabetic macular oedema whose vision remains poor despite laser treatment • People with age-related macular degeneration • Children with oculocutaneous albinism • People with optic atrophy, whatever the cause • Any person who still has difficulty performing their da...

This white paper supports the goal of establishing Computer Vision as a coherent intellectual discipline by suggesting a specific agenda for the unification of many low-level vision principles, algorithms, and data structures. Our goal is to identify a set of highly related low-level vision problems, define their common structure, and establish a coherent intellectual discipline around the shar...
