In this paper, we propose a new automatic approach to reconstructing 3-D environments using an active binocular head. To efficiently store and access the depth estimates, we propose the use of an inverse polar octree which can transform both unbounded depth estimates and unbounded estimation errors into a bounded 3-D space with appropriate resolution. The depth estimates are computed by using t...
Orbital apex syndrome (OPS) is determined by ophthalmoplegia, vision loss, and involvement of cranial nerves III, IV, VI, and the first branch of the trigeminal nerve. The disease is commonly caused by invasive fungal infections such as mucormycosis and aspergillosis in immunocompromised or immunocompetent patients. Rarely, herpes zoster virus may cause OPS. This report presents the case of a 4...
Vision contributes to upright postural control by providing afferent feedback to the cerebellum. Vision is generally classified into central and peripheral vision, but little is known about the respective role of central and peripheral vision for postural control with different visual acuity levels. This study examined the influence of visual acuity and visual field conditions on upright postur...
Background and purpose: Age related macular degeneration is the most common cause of sever visual impairment and blindness among adults over the age of 65 years in developed countries. The purpose of this study was to review the literature on using low vision aids in age related macular degeneration and their effects on their quality of life. Materials and methods: A comprehensive search of ...
