Amblyopia

Question 1

Defect of central vision.

Answer 1

Amblyopia

Question 2

If you have Amblyopia what are some of the diseases that you can get

Answer 2

Strabismus
Anisometropia
Stimulus Deprivation

Question 3

True or False. Children with amblyopia or at risk for
amblyopia should be identified at a young age
when the prognosis for successful treatment is
best.

Answer 3

True

Question 4

It is a classification of Ambyopia taht results from
competitive or inhibitory interaction between
neurons carrying the nonfusible inputs from
the two eyes.

Answer 4

Strabismic Amblyopia

Question 5

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

Answer 5

Anisometric Amblyopia

Question 6

1-2D

Answer 6

Mild hyperopic or

astigmatic anisometropia

Question 7

Less than 3D

Answer 7

Mild myopia anisometropia

Question 8

Less than 6D

Answer 8

unilateral high myopia

Question 9

True or False. The eyes of a child with anisometropic
amblyopia look normal to the family and
primary care physician.

Answer 9

True

Question 10

Result from large, approximately equal, uncorrected refractive error in both eyes of a young child.

Answer 10

Isometric Amblyopia

Question 11

Hyperopia exceeding 5D & myopia excess of

10 D

Answer 11

Risk Bilateral Amblyopia

Question 12

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

Answer 12

Meridional Amblyopia

Question 13

It is usually caused by congenital or early

acquired media opacity.

Answer 13

Stimulus Deprivation Amblyopia

Question 14

True or False. In children younger than 6 years with
congenital cataract that occupy the central
3mm or more of the lens, must be considered
capable of causing severe amblyopia.

Answer 14

True

Question 15

True or False. Similar lens opacities acquired after 6 years are generally less harmful.

Answer 15

True

Question 16

A form of deprivation caused by excessive therapeutic patching.

Answer 16

Occlusion Amblyopia

Question 17

True or False. Small polar cataracts & lamellar cataracts may cause mild to moderate amblyopia or may have
no effect on visual development.

Answer 17

True

Question 18

Give atleast 1 diagnosis

Answer 18

Characteristics of vision alone cannot be used
to reliably differentiated amblyopia from other
form of visual loss.

Question 19

Give atleast 1 diagnosis

Answer 19

The crowding phenomenon is typical for

amblyopia but not uniformly demonstrable.

Question 20

Give atleast 1 diagnosis

Answer 20

Afferent pupillary defect are Characteristic of optic nerve disease but occasionally appear to be present with amblyopia

Question 21

Give atleast 1 diagnosis

Answer 21

Multiple assessment using a variety of tests or
performed on different occasions are
sometimes required to make a final judgment
concerning the presence and severity of
amblyopia.

Question 22

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 22

Binocular Fixation Pattern

Question 23

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

Answer 23

Crowding bar or

Contour interaction bars

Question 24

Treatment for Amblyopia

Answer 24

Correcting refractive error

Question 25

Treatment for Amblyopia

Answer 25

Forcing use of the poorer eye by limiting use

of the better eye.

Question 26

It is the most powerful means of treating of

amblyopia by enforced use of the defective eye.

Answer 26

Occlusion Therapy

Question 27

Defined as occlusion for 1-6 hours per day.

Answer 27

Part Time Occlusion

Question 28

This form of treatment has recently been
demonstrated to be as effective as patching for
mild to moderate amblyopia.

Answer 28

Penalization

Question 29

Penalization is composed of

Answer 29

atropine 1% or

homatropine 5%

Question 30

True or False. When amblyopia treatment is discontinued after fully or partially successful completion, approximately half of patients show some degree of recurrence.

Answer 30

True
