Accommodative Vergence Dysfunction

Question 1

Occurs when the amplitude of accommodation (AA) is lowerthan the expected AA for the patient’s age

Answer 1

Accommodative Insufficiency

Question 2

is a condition in which the AA is normal,

Answer 2

Ill Sustained Accommodation

Question 3

Also called as accommodative inertia

Answer 3

Accommodative Infacility

Question 4

rare condition in which the accommodative system fails to

respond to any stimulus.

Answer 4

Paralysis of Accommodation

Question 5

the result of overstimulation of the parasympathetic nervous system.

Answer 5

Spasm of Accommodation

Question 6

(overaccommodation, overconvergence and miotic pupils) is also known as

Answer 6

(SNR) Spasm of Near Reflex

Question 7

occurs when the accommodative system is slow in making a change, or when there is a considerable lag between the
stimulus

Answer 7

Accommodative Infacility

Question 8

Receded near point of convergence

Answer 8

Convergence Insufficiency

Question 9

What composes the Spasm of Near Reflex

Answer 9

Overaccommodation,overconvergence and miotic pupils

Question 10

Meaning of PFC

Answer 10

Positive Fusional Convergence

Question 11

Meaning of NRA

Answer 11

Negative Relative Accommodation

Question 12

Meaning of NPC

Answer 12

Near Point of Convergence

Question 13

Can be described as exophoria or exotropia at far greater than the near deviation by at least 10 prism diopters (PD).

Answer 13

Diverging Excess

Question 14

Can be described as exophoria or exotropia at near greater than the far deviation by at least 10 prism diopters (PD).

Answer 14

Convergence Insufficiency

Question 15

has a deviation of similar magnitude at both distance and near Or if the difference between the far and near exophoria is below 10PD.

Answer 15

Basic Exophoria

Question 16

The etiology of the higher esodeviation at near most
commonly is indicated by a high accommodative
convergence/accommodation (AC/A) ratio.

Answer 16

Convergence Excess

Question 17

tonic esophoria is high when measured at distance but less at near.

Answer 17

Divergence Insufficiency

Question 18

has high tonic esophoria at distance, a similar degree of esophoria at near, and a normal AC/A ratio.

Answer 18

Basic Esophoria

Question 19

often have normal phorias and AC/A ratios but

reduced fusional vergence amplitudes. Their zone of clear, single binocular vision is small.

Answer 19

Fusional Vergence Dysfunction

Question 20

May be either comitant and idiopathic or noncomitant, due to muscle paresis or other mechanical cause.

Answer 20

Vertical Heterophorias

Question 21

Has different phorias in far and near.

Answer 21

Mixed Phoria
