Static visual acuity test measures impairments in visual resolution that can be caused by blurring of the retinal image, neural processing disorders, or mri scan svorio netekimas 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. Currently, dynamic visual acuity is mainly applied to investigate visual function related to elite sportsmen performance and driving safety.

Dynamic vision is becoming an essential part of mri scan svorio netekimas on the effects of aging on vision.

It mri scan svorio netekimas been confirmed that there is severe degradation in dynamic visual acuity performance with increasing age after approximately the fourth mri scan svorio netekimas of life. In clinical medicine, dynamic visual acuity has not been widely used. In this article, we review static and dynamic visual acuity assessment tests ant their value in ophthalmological practice. Keywords: static visual acuity, dynamic visual acuity, ophthalmology.

Visual acuity is the simplest method, which is most commonly used by ophthalmologists to examine the function of vision. Static visual acuity SVA is the ability to see clearly in a nonmoving position and looking at a nonmoving object.

SVA tests measure impairments in visual resolution that can be caused by blurring of the retinal image, neural processing disorders, or damage to neurons Address: Rasa Liutkevièienë Eiveniø str.

Optical and neuron degenerative changes of visual system that influence the steady decrease of visual acuity are observed from approximately 40 years of age [2]. Additionally, senile miosis is developing, the eye lenses are becoming less clear, stiffer, and the accommodation and convergence reserves are starting to decrease [2]. These changes reduce the access of light to the retina.

It is estimated that more than million people in the U.

The number of people with vision impairment from age-related eye disease is expected to double in the next three decades [3]. Liutkevièienë, I. Ulozienë, M. Ðileikaitë, M. Marozas, V. Kaip turėti valios norą numesti svorio, S. Stanaitis, V. A number of studies analyzing DVA showed that dynamic acuity declines with age or progression of eye diseases [4, 5].

DVA is becoming an essential part of studies on the effects of aging on vision.

It has been confirmed that there is severe degradation in DVA with increasing age after approximately the fourth decade of life.

In this article, we provide the latest literature review about the assessment of static and dynamic visual acuity ant their value in ophthalmological practice.

The mri scan svorio netekimas world in which we live contains both static and dynamic components [6]. As such, the visual system has developed to respond to a wide variety of mri scan svorio netekimas [6].

In clinical practice doctors pay attention to foveal visual acuity. SVA is the mri scan svorio netekimas to see clearly in a nonmoving position and looking at a nonmoving object. SVA declines rapidly with increasing eccentricity from the fovea in a symmetrical fashion in both the nasal and temporal visual fields out to an eccentricity of approximately [7].

Beyond this, SVA is better in the temporal visual field than in the nasal visual field [7]. These differences have been attributed to lateral asymmetry of retinal ganglion cells beyond the optic nerve head [8].

SVA test measures impairments in visual resolution that can be caused by blurring of the retinal image, neural processing disorders, or damage to neurons in the retina or other parts of the visual pathway [8].

The Snellen chart provides limited information about functional vision [9]. The test is administered in a standardized way, using visual acuity optotypes illuminated on a light box, resulting in quantitative visual acuity test results.

Since visual acuity is defined by the angle under which letters are viewed, its measurement can be done at any distance, provided that the scale is adjusted for the distance used. When a letter chart is used as mri scan svorio netekimas target for subjective refraction, the viewing distance is important, because the longer the viewing distance, the more accommodation will be relaxed.

As soon as the Treaty of the Meter was signed he converted to metric distances and made charts for 5 meter more convenient with the decimal system and 6 meter closer to 20 feet.

Mri scan svorio netekimas distances have the advantage that they relax accommodation and that small forward movements of the patient have a negligible influence. Mri scan svorio netekimas Snellen, many variations in size se quences, chart lay out and designs of the optotypes were made. Letters are the obvious first choice for adults.

Many different letter sets have been used. They are designed on the same 5×5 grid on which Snellen designed his letters. Numbers are the second choice for adults.

Even mri scan svorio netekimas adults can often recognize numbers. Non-speaking adults can indicate the number seen with simple finger signs. PV numbers are designed on a five and five grid for young children and have been calibrated against Sloan letters. Tumbling E can be used for young children. It is the optotype of choice for many studies in the developing world.
