Accommodative and Vergence Dysfunction Flashcards
It occurs when the amplitude of accommodation (AA) is lower than the expected AA for the patient’s age and is not due to sclerosis of the crystalline lens.
Accommodative Dysfunction
It is a condition in which AA is normal but fatigue occurs with repeated accommodative stimulation.
Ill-Sustained Dysfunction
Accommodative Infacility is also called as?
Accommodative Inertia
It occurs when the accommodative system is slow in making a change, or when there is a considerable lag between the stimulus to accommodation and the accommodative response.
Accommodative Infacility / Accommodative Inertia
A rare condition in which the accommodative system fails to
respond to any stimulus.
Paralysis of Accommodation
Paralysis of Accommodation can be caused by cycloplegic drug.
True
It is the result of overstimulation of the parasympathetic nervous system.
Spasm of Accommodation
Can be described as exophoria or exotropia at near greater than the far deviation by at least 10 prism diopters (PD).
Convergence Insufficiency
Can be described as exophoria or exotropia at far greater than the near deviation by at least 10 prism diopters (PD).
Divergence Excess
If the difference between the far and near exophoria is
below 10PD.
Basic Exophoria
Can be described as esophoria or esotropia at near greater than the far deviation by at least 10 prism diopters (PD).
Convergence Excess
Can be described as esophoria or esotropia at far greater than the near deviation by at least 10 prism diopters (PD).
Divergence Insuffiency
If the difference between the distance and near esophoria is below 10PD.
Basic Esophoria
Patients with _____ often have normal phorias and AC/A ratios but reduced fusional vergence amplitudes.
Fusional Vergence Dysfunction
Has different phorias in far and near.
Mixed Phoria
