Happens slowly over time

Changes to shape of eye over time
Secondary Glaucoma

an be caused by secondary like diabetes or cataracts
•
Can be either of the “angled” glaucomas
•
Normal-tension glaucoma
can happen even if the eye
pressure is normal
Incapacitating Episode
•
For purposes of evaluation, it is an eye condition
severe enough to require a clinic visit to a provider
specifically for treatment purposes.
General Rating Formula
for Diseases of the Eye
Episodes needing 7 or more tx over 12 months -------
60

pisodes
needing

Visual Acuity Ratings
•
Condition can be Unilateral or Bilateral
•
Dependent upon eye score and field of vision
•
As visual field shrinks, rating goes up (Bilateral)
Do any of the conditions rate 100%?
•
Tuberculosis of the eye (active)
•
Malignant neoplasms of the eye, orbit, and adnexa
(excluding skin)
Cataracts
•
If replacement lens present, evaluate under the general
rating formula for diseases of the eye.
•
If no replacement lens, evaluate based on aphakia
•
Minimum rating (Unilateral or Bilateral) -------
30
What about SMC?
•
Blindness
in both eyes ------- L
•
Blind
in one eye and total blindness in the other
eye with only the ability to perceive light --- L 1/2
Questions?
Glaucoma is a group of eye conditions that can lead to irreversible vision loss. There are different types such as open-angle, closed-angle, secondary, and normal-tension glaucoma, each with unique characteristics and causes. Symptoms vary from rapid damage in closed-angle glaucoma to gradual peripheral vision loss in open-angle glaucoma. Prompt diagnosis and treatment are crucial to prevent vision impairment.
