strabismus and amblyopia

Question 1

Esotropia

Answer 1

Esotropia (the eye turns inward)

Question 2

Exotropia

Answer 2

Exotropia (the eye turns outward)

Question 3

Hypertropia

Answer 3

Hypertropia (the eye turns up)

Question 4

Hypotropia

Answer 4

Hypotropia (the eye turns down)

Question 5

Sometimes, kids who are farsighted (hyperopes) develop what we call what?

Answer 5

accommodative strabismus or accommodative esotropia because they’re.overconverging while trying to focus up close. (Convergence means the turning of the eyes to focus on a near object.)

Question 6

(Convergence

Answer 6

(Convergence means the turning of the eyes to focus on a near object.)

Question 7

strabismus can be what?

Answer 7

strabismus can be either intermittent (like Abe’s was) or constant. People with intermittent strabismus are more likely to exhibit the problem when they’re tired, sick, or stressed. People with intermittent strabismus often have headaches and double vision because the brain may still be trying to use the input from the turned eye.

Question 8

don’t worry too much about this…

Answer 8

Now, here’s a reassuring note from today’s reading assignment that I’d like to reinforce: don’t worry too much if you see a baby under three or four months old with an occasionally “wandering” eye, because this can be perfectly normal in young infants as their focusing ability develops. After that age, it’s something a doctor should check out.

Question 9

Strabismus dramatically affects eyesight because it interferes with what?

Answer 9

with depth perception or stereopsis—the fusing of images from the two eyes into a clear picture. Stereopsis is what allows us to see in three dimensions.

Question 10

Stereopsis

Answer 10

the fusing of images from the two eyes into a clear picture. Stereopsis is what allows us to see in three dimensions.

Question 11

The most common tools we use to treat strabismus are:

Answer 11

eye muscle surgery and vision therapy.

Question 12

orthoptics.

Answer 12

(which means straight eyes) is the science of using instruments to help realign the eyes. Often, we prescribe this therapy after patients have eye muscle surgery. Opticians who work in this area are called orthoptists.

Question 13

Why doesn’t surgery alone fix the problem?

Answer 13

Why doesn’t surgery alone fix the problem? Here’s the answer. When a person who’s had misaligned eyes for some time has surgery to align the eyes, the straightened eye has to start using a different part of the retina. Vision therapy exercises help train that new part of the retinal nerve fiber layers to receive signals and transport them to the brain.

Question 14

Vision therapy involves what?

Answer 14

Vision therapy involves orthoptics, but it also includes eye exercises that can improve visual and perceptual efficiency even if the eyes are straight. The approaches you’ll use in vision therapy include computer programs, lenses, prisms, eye patches, and eye-hand coordination exercises

Question 15

The approaches you’ll use in vision therapy include :

Answer 15

The approaches you’ll use in vision therapy include computer programs, lenses, prisms, eye patches, and eye-hand coordination exercises

Question 16

vision therapy typically is most successful for who?

Answer 16

vision therapy typically is most successful for young children

Question 17

monocular vision

Answer 17

monocular vision—that is, vision in only one eye

Question 18

prism lenses.

Answer 18

prism lenses. These are lenses that have a thick base and a thin apex (top).

Question 19

Prisms do what to an image

Answer 19

Prisms displace an image, making it appear in a different direction. This moves the patient’s eye in the desired direction. As a result, the eye will appear straighter, and the relocated image will allow the two eyes to work together better.
