The goal of a regular eye exam
• Check general eye health
• To diagnose any eye problems
• To develop a treatment plan to address disease and
•
refraction errors
To maximize vision using traditional glasses or
contact lenses or refer for lasik surgery

What constitutes a “regular” eye
exam?
SOAP format
• S = subjective
• O = objective
• A = assessment
• P = plan

Subjective
• Patient History





“What’s going on?”
“Where is problem?” – (Which eye?)
“When did it start?”
“Why?” – (Did something cause problem?)
Modifiers
 Severity?, How often?, Does anything help?

7
Subjective (cont.)
 Medical History –
 Health history
 Meds - Rx, OTC, vitamins/supplements
 Previous eye care
 Brief Psychological evaluation
 O X 3 = oriented to person, place and time (date,
year, etc.) – Medicare requires this for a
comprehensive exam

Objective Testing
• Visual acuity = VA
s = without correction, c = with correction
 DVA = distance, NVA = near
 OD = right eye, OS = left eye, OU = both eyes
 BVA = Best Corrected Visual Acuity
 Charts
 Snellen (or POC = “Project-o-Chart)
 = standard chart – gives 20/XX #’s - 1st 20 = test
distance (20 feet). 2nd number = size of letter seen.

Intra Ocular Pressure
• IOP 10-21 normal
• Glaucoma is now diagnosed by changes in the disk to
ratio, not simply intra-ocular pressure readings

The Numbers
• IOP = intraocular pressure – measured by tonometry –
applanation, non-contact (“air puff”), old style = Schiotz
 Expressed in mmHg (millimeters of mercury – just like
a barometer)
 Glaucoma – pressure in the eye too high for the eye
to handle. Normal range = 10 – 21 mmHg. Can have
normal pressure and still have glaucoma (GLC). Can
have higher than normal pressures and NOT have
glaucoma.

Assessment
• Also called Impression
 What the doctor thinks is going on
 Examples = AMD (macular degeneration), GLC
(glaucoma), BDR (non-proliferative or background
diabetic retinopathy), PDR (proliferative diabetic
retinopathy), Cataracts (NS = nuclear sclerosis),
Myopia (near-sighted), Hyperopia (far-sighted),
Presbyopia (you need bifocals)

 Medical management
 Drug therapy
 Surgery
 Observation
 Optical management
 Glasses or contacts

The goal of a Low Vision
Evaluation
• To confirm findings of eye report
• To maximize functional vision through low vision aids,
therapies, environmental modifications and patient
strategies

Low Vision Evaluation - History
• What is pt having trouble doing?
• Be specific – i.e. “How far are you sitting from
•
•
the TV? What type of reading light do you use?
How much reading do you need to do? Glare?
Vocation? Hobbies? Computer use?, etc.”
Glasses? (How old?) Contacts? What
magnifiers do you use now? (Look for “buzz
words” – i.e. “reading machine” = CCTV)
What is the one thing you want to do most?

31
Low Vision Evaluation
• Similarities to standard exam
•
 Most often will check the same areas, but with some
differences.
Differences
 History
 Most Important = functionality
 Most patients are referrals so Dx (diagnosis) is
known
 Current Medications – eye drops, orals,
supplements

32
Low Vision Evaluation History
(cont.)
• Include social info - living arrangements, transportation
•
issues (Are they still driving?!?), smoking, alcohol/drug
use
VA – most often use different charts
 Distance - Feinbloom #, EDTRS, Lea, etc.
 Why? – gradations between lines, test distances
 High contrast vs. low contrast

Low Vision Evaluation – Visual
Fields
• Confrontations - but can use to map scotomas
•
and field restrictions
Amsler grid – use for quality of macular loss
 Scotoma density
 Metamorphopsia (distortion)

Low Vision Evaluation
• Automated fields – sometimes less effective –
difficulties with fixation, etc.
 Nidek MP-1 – maps central scotomas
 Scanning laser ophthalmoscope
• Pupils/Eye movements = same but can give info
•
on undetected brain issues (stroke, etc.)
Eye health eval = seldom dilate – creates
artificial VA problems

Low Vision Aid Evaluation
• Start with what they want most
 Most often = READING!!
• Prescriptive process - Not just throwing
•
•
magnifiers at them!
May take more than one visit to determine best
aids for that person. Good to let them try before
purchase if possible.
Training on use of aids is critical.

• If you have difficulty seeing in
different situations, bring
samples.

Low Vision Evaluation –
Assessment and Plan
•
•
•
•
Diagnosis for billing purposes
Aids may or may not be Rx’d at first visit
May need additional visits
May include referral to other agencies for
services – O&M, home visits, OT/CVRT
services, VR services, Social Service agencies

Regular Exam Letter Example
Dear XXX,
I had the pleasure of seeing XXX, a very pleasant XX
year old female for a comprehensive eye exam on
XX/XX/XX. Chief complaint was blurred vision. She has
a history of macular degeneration, worse in the right eye
than the left. Medical history includes hypertension and
hypothyroid, both controlled by medication,

LV Letter Example
Dear XXXXX.
I had the pleasure of seeing your patient (client), XXX
XXXX, for a low vision evaluation on xx/xx/xx. As you
know, XXX is a very nice XX year old woman, who
suffers from macular degeneration. As you are
familiar with her medical history, I will not recount that
here. XXX lives at home with her husband.
XXX’s main concern is reading. She also has
difficulty with personal hygiene and other daily tasks.
Following is a brief summary of her evaluation:

LV Letter Example 2 (cont. 2)
With her current eyeglasses, XXX’s vision measured at
OD 10/100 (20/200) and OS 10/40 (20/80). Reading
measured at 2.5 M (large print material size). Pupil
reactions were minimal and eye movements were full.
Visual fields by confrontations/Amsler grid showed a
large dense central scotoma in the right eye and a
smaller area of metamorphopsia centrally in the left eye,
with periphery full to finger counting in both eyes.
Additional findings were consistent with the diagnosis.

LV Letter Example (cont. 3)
Various low vision aids were demonstrated. We also demonstrated
and instituted a course of eccentric viewing training. Best response
to low vision aids were: 4.0X (brand) LED lighted stand magnifier
for reading which allowed 1.0 M print (newsprint). We also
demonstrated a 4.0X LED hand magnifer for portability. For glare
issues, a medium plum sun filter (NoIR U81) was recommended.
We plan to see XXX for additional evaluation and training, at which
time we will demonstrate CCTV’s and other low vision aids.
Thank you for allowing us to share in the care of this delightful
woman. If there are questions, please feel free to contact us.
Regards
XXXX, OD

One Other Type of Assessment:
Functional Vision Assessment
• Field based – home, school, work
• Submitted by a LVT, TVI, VRT, O&M or CRC
• Friends and Family can assist with
observations
• Variety of factors beyond just eyes – fatigue,
environmental cues, experiences, glare,
contrast, etc.
52
What do those Numbers Mean?
• Visual acuity
 20/XX
 1st 20 = test distance (20 feet)
 2nd number = Letter size – based on angle
subtended in seconds of arc
 The larger the 2nd number, the worse the vision
 Many low vision doctors work in shorter distances (ex.
10 feet) so may look like 10/40 – this equates to 20/80
(7/40 = 20/125, 5/40 = 20/160, etc.)

Legal Blindness – Social
Security 1934
• Best Corrected (!!) vision of 20/200 or worse in the
•
•
better eye OR Visual field of 20 degrees or less
YOU CANNOT BE LEGALLY BLIND IN ONE EYE !!!
YOU CANNOT BE LEGALLY BLIND IF YOU VISION IS
CORRECTED BY GLASSES OR CONTACTS TO
BETTER THAN 20/200.

Eccentric viewing
• Eccentric viewing forces the use of alternate areas of
retina with lower resolution that are often located outside
of the affected foveal/macular area.
