OBJECTIVES To compare balance in individuals with symptomatic knee osteoarthritis (OA) and in age-, gender- and body-mass-matched controls using simple clinical measures. METHODS Thirty-three people with OA and 33 controls participated. Static postural sway [antero-posterior (AP), lateral and total] was measured using a swaymeter on two different surfaces and under two visual conditions. Dyna...

We describe the bi-directed eyes of a mesopelagic teleost fish, Rhynchohyalus natalensis, that possesses an extensive lateral diverticulum to each tubular eye. Each diverticulum contains a mirror that focuses light from the ventro-lateral visual field. This species can thereby visualize both downwelling sunlight and bioluminescence over a wide field of view. Modelling shows that the mirror is v...

purpose: to compare the visual outcomes and complications of lensectomy and posterior chamber intraocular lens (pciol) implantation with or without posterior capsulotomy and anterior vitrectomy in pediatric cataracts. methods: seventeen eyes of 12 children aged 10 to 15 years with congenital or developmental cataract were randomly divided into two groups. lensectomy and pciol implantation was p...

BACKGROUND Body sway increases with age. The purpose of this study was to obtain baseline data and the characteristics of balance performance in different age groups for balance strategy management. METHODS Healthy individuals (n = 107) were divided into young, middle-aged, and elderly groups, and assessed by computerized dynamic posturography (CDP) on a Smart Balance Master. The 6 subtests i...
