Balint syndrome is a disorder of inaccurate visually guided saccades, optic ataxia, and simultanagnosia that typically results from bilateral parieto-occipital lesions. Visual perception disturbances in the posterior reversible encephalopathy syndrome (PRES) include hemianopia, visual neglect, and cerebral blindness, but Balint syndrome had not been recognized. We report Balint syndrome associa...

Case report Because of disturbances in visual acuity, the patient initially turned to the services of the Timişoara Ophthalmological Clinic in 2011, and was later sent to the Infectious Diseases Clinic of Timişoara, showing low grade fever, moderate hepatosplenomegaly, discreet subicteric sclera and a severely increasing deterioration of visual acuity. Direct ophthalmoscopy revealed disseminate...

An experiment was carried out to estimate the effect of sound feedback on the work of a plant operator. Eight students of computer science operated a process simulation program of an assembly line with computer numeric controlled (CNC) robots. Relevant information of disturbances and machine breakdowns was given only in a visual (test condition 1), and in visual and audible form (test condition...

Patients with Parkinson's disease have a number of specific visual disturbances. These include changes in colour vision and contrast sensitivity and difficulties with complex visual tasks such as mental rotation and emotion recognition. We review changes in visual function at each stage of visual processing from retinal deficits, including contrast sensitivity and colour vision deficits to high...

Circles of Care grantees were provided the opportunity to develop a locally relevant definition of serious emotional disturbance that would be used to define what type of emotional, behavioral, and mental disability would be required to receive services. After conducting detailed assessments of the definition in the guidance for applicants GFA and the definitions used by others in their respect...

There is significant motivation to provide robotic systems with improved autonomy as a means to significantly accelerate deactivation and decommissioning (D&D) operations while also reducing the associated costs, removing human operators from hazardous environments, and reducing the required burden and skill of human operators. To achieve improved autonomy, this project focused on the basic sci...

PURPOSE Visual disturbances that make it difficult to read text are often termed "visual stress". Coloured filters in spectacles may help some children overcome reading problems that are often caused by visual stress. It has been suggested that for optimal effect each child requires an individually prescribed colour for each eye, as determined in systems such as the "Harris Foundation" coloured...

UNLABELLED Migraine is a central nervous system disorder frequently expressed with paroxysmal visual dysfunctions. OBJECTIVE To test the hypothesis that normal visual input is vital for the migrainous aura and photophobia. METHOD We studied the migraine-related visual disturbances in 8 sightless migraineurs identified among 200 visually impaired subjects. RESULTS The main findings were th...
