Back 19

3, 3.5, 4, 5

Front 20

What is a sign of maturity on the Incomplete Man test?

Back 20

The arm comes up is a sign of maturity on this tetst.

Front 21

What is the cause of hypothyroidism?

Back 21

The cause of this diseas is a lack of iodine or a defective thyroid.

Front 22

What chages does hypothyroidism cause to the body's metabolism and growth and body shape?

Back 22

This reduces metabolism and the child becomes dwarfish and bloated.

Front 23

What changes to a person's skin and metal development can hypothyroidism cause?

Back 23

It can cause dry, scaly, sallow skin and mild to sever mental retardation.

Back 24

The 3 types of this disorder are: Trisomy 21, 13-15 translocation, and Mosaic

Front 25

Critera for legal blindness?

Back 25

Central BVA of 20/200 or less in the better seeing eye, or central fields of 20 degrees or less.

Front 26

Criteria for partially seeing?

Back 26

BVA 20/70 to 20/200 in better seeing eye.

Front 27

Criteria for Low Vision?

Back 27

BVA of 5/200 or worse in better seeing eye.

Front 28

Two most common causes of visual impairment in children under the age of 5?

Back 28

Prenatal influence (48%), Infectious disease (23%)

Front 29

(T/F) Most children with BVA <20/200 prefer reading brail over text.

Back 29

False, they get large print or hold normal print really close.

Front 30

Binocular vision testing should be done (with/without) correction?

Back 30

With correction.

Front 31

Fixation disparity testing is done under non-fused or fused conditions?

Back 31

Fused-the misalignments tested here are very small (minutes of arc)

Front 32

What is measured on the positive side of the y-axis of a fixation disparity curve?

Back 32

Amount of ESO fixation disparity

Front 33

What is measured on the positive side of the x-axis of a fixation disparity curve?

Abnormal response to 4 base out test?

Back 45

Prism introduced to good eye shifts both eye towards apex with no re-fixation, Prism introduced to bad eye results in no movement.
