Visual acuity refers to the clarity or sharpness of vision, specifically how well an individual can see details at a certain distance. It is usually measured using an eye chart and expressed as a fraction, such as 20/20, where the top number represents the testing distance and the bottom number represents the distance at which a person with normal vision can see the same detail.
The prognosis for central retinal visual acuity is poor with only about one-third of patients recovering useful vision.
The retina, specifically the fovea, is the main structure responsible for visual acuity in the eye. The fovea is a small area at the center of the retina with a high concentration of cone cells for detailed vision. The lens also plays a role in focusing light onto the retina for clear images.
