Primary Care and Refraction Flashcards
Primary care exam sequence can be grouped into 4 general areas:
Case history
Refractive status
Binocular and accommodative status
Ocular health
Patients own account of information about his visual problems
Case history
Stimulus which primary drives the patient to seek ocular assistance
Chief complaint
Used to designate a group of symptoms arising from any form of functional eyestrain
Asthenopia
Ocular complains due to uncorrected EOR
Accommodative
Ocular complaints due to excessive lateral phorias or muscular deficiency
Motor
Ocular complains involving lowered ability to fuse, aniseikonic involvements
Integrative
Distance between the centers of the entrance pupils of the eye
Inter-pupillary distance
Distance between the centers of the entrance pupils of the eye
Inter-pupillary distance
PD method where the px’s fixation is the examiner’s eye for distance PD and examiner’s nose for near PD
Anatomical method
Method in taking PD where the patient is asked to fixate at the bulb
Catoptric method
Method in taking PD where the patient is asked to fixate at the bulb
Catoptric method
The point of intersection of the lines of sight of the eyes when maximum convergence is utilized
Near point of convergence
Measurement of the pupil size under constant stimulus
Static pupil evaluation
Measurement of changes in the pupil size with changes in stimulus conditions either of light or accommodation
Dynamic pupil evaluation
Normal pupil in bright light
2-4mm
Pupil size in dark light
4-8mm
Unequal size of pupil
Anisocoria
Convenient test for determining the presence of strabismus at near
Corneal reflex test
Deviation of the corneal reflex from the center of the pupil is estimated through
Hirschberg test
Assess the px’s ability to conjugate eye movements
Motility test
Movement of one eye in any direction
Duction
Binocular movements with two eyes moving synchronously in the same direction
