Common or concerning symptoms
Changes in vision:
HYPEROPIA
PRESBYOPIA
MYOPIA
SCOTOMAS
Is a refractive error, which means that the eye does not bend or refract light properly to a single focus to see images clearly.
HYPEROPIA
Distant objects look somewhat clear, but close objects appear more blurred.
HYPEROPIA
Is when your eyes gradually lose the ability to see things clearly up close.
It is a normal part of aging
PRESBYOPIA
Comes from a greek word which means “old eye”
PRESBYOPIA
You may start to notice presbyopia shortly after age
40
Is a common vision condition in which you can see objects near to you clearly, but object farther away are blurry.
MYOPIA
It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your retina
MYOPIA
Is an area of partial alteration in the field of vision consisting of a partially diminished or entirely regenerated visual acuity that is rounded by a field of normal - or relatively well preserved - vision
SCOTOMAS
DOUBLE VISION
DIPLOPIA
Is when your eyes are not lined up properly and they point in different directions

PHYSICAL EXAMINATION
Components of the eye examination include:
VISION TESTS
EXTRAOCULAR MOVEMENTS
Distal, near, and peripheral inspection of the eye, eyebrows, lids, conjunctiva and sclera, cornea, lens, Iris, and pupils inspection and palpation of the lacrimal apparatus
VISION TESTS
Assessment of cardinal fields, convergence, corneal light test, cover-uncover test
EXTRAOCULAR MOVEMENTS
equipment for examination
SNELLEN CHART OR “E” CHART
ROSENBAUM, NEAR-VISION CARD
INDEX CARD
OPTHALMOSCOPE
Visual acuity is expressed as two numbers
20/30
The numerator indicates the distance of the patient from the chart and this number should always be 20 unless the patient moved closer to see, and the denomination is the distance at which a normal eye can read the line of letters
VISUAL ACUITY
Testing ________ with a special hand held card
NEAR VISION
Helps Identify the need for reading glasses or bifocals in patients older than 45 years
ROSENBAUM CHART
This card can be utilized to test visual acuity at the bedside.
Held 14 inches from the patient’s eyes, the card simulates a snellen chart.
HAND HELD CARD
External eye examination
POSITION AND ALIGNMENT OF THE EYE
EYEBROWS
EYELIDS
Stand in front of the patient and survey the eyes for position and alignment. If one or both eyes seems to protrude, assess them from above
POSITION AND ALIGNMENT OF THE EYES
Inspect for the following:
Open are between the upper and lower eyelids
WIDTH OF THE PALPEBRAL FISSURES
