Q

A form of deprivation caused by excessive therapeutic patching.

A

Occlusion Amblyopia

17
Q

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

18
Q

Give atleast 1 diagnosis

A

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

19
Q

Give atleast 1 diagnosis

A

The crowding phenomenon is typical for

amblyopia but not uniformly demonstrable.

20
Q

Give atleast 1 diagnosis

A

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

21
Q

Give atleast 1 diagnosis

A

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.

22
Q

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.

A

Binocular Fixation Pattern

23
Q

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

A

Crowding bar or

Contour interaction bars

24
Q

Treatment for Amblyopia

A

Correcting refractive error

25
Treatment for Amblyopia
Forcing use of the poorer eye by limiting use | of the better eye.
26
It is the most powerful means of treating of | amblyopia by enforced use of the defective eye.
Occlusion Therapy
27
Defined as occlusion for 1-6 hours per day.
Part Time Occlusion
28
This form of treatment has recently been demonstrated to be as effective as patching for mild to moderate amblyopia.
Penalization
29
Penalization is composed of
atropine 1% or | homatropine 5%
30
True or False. When amblyopia treatment is discontinued after fully or partially successful completion, approximately half of patients show some degree of recurrence.
True
