Abstract
Static visual acuity is the ability to see clearly nonmoving object from stationary position. Static visual acuity tests measure impairments in visual resolution that can be caused by damage in anterior segment, blurring of the retinal image, neural processing disorders, or damage to neurons in the retina or other parts of the visual pathway. Dynamic visual acuity refers to the ability to resolve a target visually when there is relative motion between the target and the observer. The semicircular canals and otolith organs of the peripheral vestibularend organ are essential for maintaining gaze and gait stability during motion. This is achieved by efference from the vestibular ocular reflex and the vestibulospinal reflexes. Damage to semicircular canals and/or otolith organs causes impaired visual acuity during head rotation; impaired balance and postural control; and symptoms of vertigo, falling, nausea, and disorientation.In this article we review about static and dynamic visual acuity value in ophthalmological and otorhinolaryngological practice.
