Inspection- General eyelids, lashes, eyeballs, conjunctiva, sclera,
evernsion of upper lid, and lacrimal apparatus
Equipment Needed
Snellen Chart
Handheld visual screener
Opaque card or occular
Penlight
Applicator stick
Opthalmoscope
●● How do you examine the Ocular Fundus?
Answer: Stand directly in front of client (10 inches), use the
ophthamoscope to look inside eye and you should see a red reflex.
,●● What is the red reflex?
Answer: it is the reflection of the ophthalmoscope light off the inner
retina
●● What does the confrontation test determine?
Answer: it determines the loss of peripheral vision.
●● Snellen Eye Chart
Answer: is a alphabet chart that is commonly used to measure visual
acuity.
●● How would you use the Snellen Chart to test visual acuity of a
patient?
Answer: Have the patient...
Stand 20 feet from the chart
Use an opaque card to shield one eye at a time
Ask the patient to read through the chart to the smallest line.
Perform test with perscription glasses/contact on
●● what is normal visual acuity?
Answer: 20/20
,●● If the patient is unable to read the largest letter of the Snellen chart,
what do you do?
Answer: shorten the distance until it become clear enough for them to
read and record that distance.
●● What does the numeric fraction mean for the results of the Snellen
Chart Exam?
Answer: the top number/numerator indicates the distance the person is
standing from the chart.
the bottom number/denominator indicates the diatance at which a normal

Answer: Corneal Light Reflex ( shine light in eye)
Diagnostic Postion Test (follow my finger- star burst shape/6 Cardinal
Positon)
, ●● palpebral fissure (External Anatomy)
Answer: the elliptical open space between the eyelids
●● limbus (External Anatomy)
Answer: border between cornea and sclera
●● Canthus (External Anatomy)
Answer: the corner of the eye, the angle where the lids meet.
●● tarsal plates (External Anatomy)
Answer: are strips of connective tissue that give it shape
●● conjunctiva (External Anatomy)
Answer: a thin mucous membrane folded like an envelope between the
