every 4- 6weeks.

3. Surgical ocular alignment

Question 11

occurs at a later age than infantile

Answer 11

Acquired eso/exo

Question 12

– associated with the activation of Acc.

– attributed partly to either uncorrected hyperopia and/or high Accommodative Convergence/Accommodat ion (AC/A) ratio.

Answer 12

Accommodative esotropia

Question 13

– not associated w/ accommodative effort

– correction of hyperopia and/or prescribing near add has minimal or no effect

Answer 13

Non-accommodative esotropia

Question 14

– caused by a mechanical restriction or tightness or a physical obstruction of the EOM

– can either be congenital or acquired

Answer 14

Mechanical eso/exo

Question 15

– rarely deteriorates to constant exotropia

Answer 15

Question 16

Results from a primary sensory deficit or as a result of surgical intervention

Answer 16

Secondary eso/exo

Question 17

results from visual deprivation or trauma in one eye.

Answer 18

Consecutive eso/exo

Question 19

– angle of deviation is less than 10PD

– constant and usually unilateral

– frequently results from the Tx of a larger scale deviation.
