Study Notes
Vitreous Humor and Liquids
- Vitreous humor is thick, while other liquids in the eye are thin
Color Vision and Rods
- Rods help individuals see shades of grey
- Ask about family history of glaucoma, diabetes, blindness, and cataracts for assessment of color vision
Visual Acuity Tests
- Snellen chart: uses alphabetical letters with largest letters on top, progressing to smallest
- E-chart: used for individuals with reading problems, indicates direction of the letter E
- Normal vision: 20/20, patient can read at 20 feet what the normal eye can read at the same distance
Assessment of Eye and Vision
- Low vision: occurs at 20/70
- Legal blindness: occurs at 20/200
- Documentation: OD - right eye, OS - left eye, OU - both eyes
- Must include "with" or "without" correction
Peripheral Vision
- Ability to see objects on the sides when eyes are forward
- Assessment of peripheral vision
Muscle Balance and Movement
- Test to follow examiner's fingers with eyes forward in all 6 cardinal fields of gaze
- Checks for muscle strength and balance of eye, and functioning of cranial nerves 3, 4, and 6
- Six Cardinal Fields of Gaze: assessment of muscle balance and movement
Important Terms
- Esotropia: deviation of the eye towards the nose
- Exotropia: deviation of the eye away from the nose
- Hypotropia: deviation of eye downward
- Hypertropia: deviation of the eye upward
- Perrla: pupils equal, round, reactive to light and accommodation
