- Visual Acuity Testing - University of Iowa
Visual acuity testing also allows assessment of eccentric viewing postures, scanning abilities and motivation Visual acuity testing does not tell us about the individual’s quality of vision It only speaks to the patient’s quantity of vision We will discuss quality versus quantity of vision in a few minutes Slide 5
- Contrast Sensitivity Testing - University of Iowa
Visual acuity testing also allows assessment of eccentric viewing postures, scanning abilities and motivation That said, visual acuity testing does not tell us about the individual’s quality of vision It only speaks to the patient’s quantity of vision Slide 4 Let’s talk about visual quality versus visual quantity
- Basic Pediatric Eye Exam - University of Iowa
Visual Acuity Next, we will assess visual acuity Normal visual responses vary depending on the age of the child At all ages, assessing for symmetry of vision or preference for one eye is critical In babies up to three months old, blinking or wincing to light is an appropriate response
- Tutorial: Binocular Vision - University of Iowa
Thus the visual acuity is not reduced under monocular conditions and there are no uniocular scotomas in the visual field Obligatory- Obligatory suppression is the effect which carries on even under monocular conditions resulting in diminution of visual acuity Amblyopia is the fallout of this obligatory suppression

One method of visual acuity testing in preverbal or nonverbal children is the CSM method C refers to centrality and can be assessed by the location of the corneal light reflex as the patient looks at the examiner's light with the opposite eye occluded
- Plus Cylinder Subjective Refraction Instructional Video
It is important to know that the acuity charts in shorter exam rooms are adjusted to the correct letter height for the room's testing distance, so the visual acuity measured in a shorter exam room is the correct acuity Finally, with respect to visual acuity testing, when a patient leans in to see the chart better, the testing distance can be
- Pediatric Visual Acuity Testing - University of Iowa
Dr Scheiman determined visual acuity ranges at different ages using Teller Cards On this chart you see that the visual acuity of a normally sighted child ranges from 20 400 to 20 1200 at 1 month of age and improves via the visual maturation process to the 20 20 to 20 50 level at 30 months of age
- Visual Field Testing: From One Medical Student to Another
Visual acuity (which is a measure of central vision) may remain 20 20, but the peripheral field of vision may be severely reduced Patterns of Visual Field Loss [7,8,9] Damage to visual mechanisms along various portions of the visual pathways from the optics and photoreceptors up to the visual centers of the brain will produce different shapes
- Near visual acuity - University of Iowa
Near visual acuity Richard C Allen, MD, PhD, FACS Additional Notes: Length 00:28 Near visual acuity is determined with the patient wearing their glasses Each eye is evaluated separately The patient holds a near card at a comfortable distance, usually about 18 inches The patient should then read the smallest print possible
