Amblyopia

Question 1

It is a primarily defect of central vision.

Answer 1

Amblyopia

Question 2

The most common form of amblyopia

Answer 2

Strabismic Amblyopia

Question 3

It is thought to result from competitive or inhibitory interaction between neurons carrying the nonfusible inputs from the two eyes.

Answer 3

Strabismic Amblyopia

Question 4

It develops when unequal refractive error in the two eyes causes the image on the one retina to be chronically defocused.

Answer 4

Anisometropic Ambyolpia

Question 5

It is the result from large, approximately equal, uncorrected refractive error in both eyes of a young child.

Answer 5

isometropic amblyopia

Question 6

Uncorrected bilateral astigmatism in early childhood may result in loss of resolving ability limited to chronically blurred meridians.

Answer 6

Meridional amblyopia

Question 7

It is usually caused by congenital or early acquired media opacity.

Answer 7

Stimulus Deprivation Amblyopia

Question 8

This form of amblyopia is the least common but most damaging and difficult to treat.

Answer 8

Stimulus Deprivation Amblyopia

Question 9

It is a form of deprivation caused by excessive therapeutic patching.

Answer 9

Occlusion amblyopia

Question 10

a test for estimating the relative level of vision in the two eyes for children with strabismus who are under the age of about 3.

Answer 10

Binocular fixation pattern

Question 11

A diagnosis that can directly measures acuity in children 3-6 years old.

Answer 11

modified Snellen technique

Question 12

A test that allows the examiner to test the crowding phenomenon with isolated optotype. Bar surrounding the optotype mimic the full optotype to the amblyopic child.

Answer 12

Crowding bar, or contour

interaction bars

Question 13

Cite any treatment for amblyopia

Answer 13

Eliminating (if possible) any obstacle to vision such as a cataract
■ Correcting refractive error
■ Forcing use of the poorer eye by limiting use of the better eye.

Question 14

Removal of significant congenital lens opacities during the first 2-3 months of life is necessary for optimal recovery of vision.

Answer 14

Cataract Removal

Question 15

TRUE OR FALSE. An amblyopic person can be a candidate for cycloplegic refraction

Answer 15

True

Question 16

It is the most powerful means of treating of amblyopia by enforced use of the defective eye.

Answer 16

Occlusion and optical degradation

Question 17

Defined as occlusion for 1-6 hours per day.

Answer 17

Part-time occlusion

Question 18

Hyperopia exceeding ___ is a risk for bilateral amblyopia

Answer 18

5D

Question 19

Myopia with exceeding ___ is a risk for amblyopia

Answer 19

10D

Question 20

cause mild to moderate amblyopia or may have no effect on visual development.

Answer 20

Small polar cataracts & lamellar cataracts

Question 21

Unilateral or less commonly, bilateral reduction of best corrected visual acuity that can not be attributed directly to the effect of any structural abnormality of the eye or the posterior visual pathway. Defect of central vision.

Answer 21

Amblyopia
