PRELIMINARY TEST PROCEDURES Flashcards
this test uses ophthalmoscope while instructing the patient to look directly into the light.
observe the hirschberg reflex as well as the brightness of the red reflex in each eye then compare
bruckner
to gather information about the patient’s chief complaint, visual function, risk factors and lifestyle
to begin the process of differential diagnosis
to begin the process of patient education
to establish a caring relationship with patient, compassion and respect
case history taking
to measure the clarity of vision or the ability of visual system to resolve details
visual acuity
equipment needed for VA taking
Projector with VA slide, computer- generated acuity chart
Near point VA Card
Occluder
Lamp
Projector or computer- (generated charts should be calibrated or the
distance room the patient to the chart)
equipment needed for external observation
pupil gauge
penlight
equipment for Pinhole VA
Projector with VA slide, computer- generated acuity chart, or wall mounted acuity chart
Pinhole (PH) disc with 1.0- to 1.5-mm diameter pinhole(s).
Occluder
equipment for near point of accommodation
near point visual acuity card
tape measure in cm
opaque occluder
equipment for measuring the IPD
ruler in mm
penlight
types of pupillary distance measurement
catoptric
anatomical
catoptric vs anatomical
catoptric uses penlight to observe the corneal reflex as the measuring point on right and left
anatomical does not use penlight, measure outer limbus from on eye to the inner limbus on the other eye
