The prognosis for central retinal visual acuity is poor with only about one-third of patients recovering useful vision.
Yes, it is possible to have good visual acuity while experiencing poor peripheral vision. Visual acuity refers to the sharpness or clarity of vision, typically assessed in the central vision where details are most clearly perceived. Peripheral vision, on the other hand, involves the ability to see objects outside of the direct line of sight and can be affected by various conditions, such as glaucoma or retinal issues. Thus, an individual may have sharp central vision but still struggle with detecting objects or movement in their peripheral field.
The ability to see clearly is called visual acuity
the scale of the visual acuity is snelle chat
The fovea or fovea centralis that is a pit in the central region of the macula of the retina with a high concentration of cone photoreceptors (red, blue and green) that allows for 100% visual acuity including color vision comprises less than 1% of retinal size but takes up over 50% of the primary visual cortex in the brain.
6/6. Six by six is normal visual acuity.
Retinal
Visual acuity NI refers to "visual acuity not indicated," often used in medical contexts when a patient's visual acuity has not been assessed or recorded. It may occur in situations where vision tests are not performed due to various reasons, such as the patient's condition or inability to participate in the assessment. This designation highlights the absence of measurable visual acuity data for that individual.
The area of greatest visual acuity in the human eye is the fovea, which is a small pit in the retina at the center of the macula. This is where the highest concentration of cone cells is found, allowing for detailed and sharp central vision.

A cyclist needs good visual acuity
The greatest visual acuity in the eye is found in the fovea, a small depression in the retina. The fovea is densely packed with cone photoreceptors, which are responsible for high-resolution color vision. This area allows for sharp central vision, essential for activities like reading and recognizing faces. As you move away from the fovea, visual acuity decreases due to a lower concentration of cones.
static visual acuity is the ability to see clearly and a non moving position and looking at a non moving object.
