1.
Which of the following represents a general ocular change in the geriatric population that could be a sign of kindey/heart failure and thyroid disease.
Correct Answer
A. Baggy eyelids
Explanation
Baggy eyelids in the geriatric population could be a sign of kidney/heart failure and thyroid disease. This is because as people age, the skin loses its elasticity and the muscles supporting the eyelids weaken, resulting in sagging or baggy eyelids. In cases of kidney or heart failure, fluid retention can occur, leading to swelling around the eyes and causing baggy eyelids. Thyroid disease can also cause changes in the skin, including the eyelids, due to hormonal imbalances. Therefore, baggy eyelids can be a general ocular change in the geriatric population that may indicate underlying kidney/heart failure or thyroid disease.
2.
Indicate ALL of the following that INCREASE with age.
Correct Answer(s)
B. ATR astigmatism
D. Lens thickness
E. IOP
G. Aqueous production
Explanation
As individuals age, several factors tend to increase. ATR astigmatism refers to astigmatism that is more pronounced in the horizontal meridian, and this tends to increase with age. Lens thickness also tends to increase as the lens becomes less flexible and more rigid over time. Intraocular pressure (IOP) can also increase with age due to changes in the balance of fluid production and drainage in the eye. Finally, aqueous production, which refers to the production of the fluid in the front part of the eye, tends to increase as individuals age.
3.
Indicate ALL of the following structures/physio mechs that do NOT change with age.
Correct Answer
A. Aqueous composition
Explanation
The aqueous composition refers to the fluid that fills the anterior chamber of the eye. This fluid is responsible for maintaining the shape of the eyeball and providing nutrients to the surrounding tissues. The answer suggests that the aqueous composition does not change with age. This is because the composition of the aqueous humor remains relatively stable throughout life, ensuring proper eye function and maintaining a healthy intraocular environment.
4.
Phorias tend to shift to become more EXO.

5.
Which of the following types of cataracts would be the worst in conjunction with a miotic pupil?

6.
A patient with normal visual fields should be expected to lose how many degrees per decade?
Correct Answer
A. 1-3
Explanation
As a person ages, it is normal for them to experience a gradual decline in their visual fields. This decline typically occurs at a rate of 1-3 degrees per decade. This means that over the course of 10 years, a person may lose 1-3 degrees of their visual field. This is considered to be within the range of normal age-related changes in vision.

12.
BCC is more common than SCC
Correct Answer
A. True

BCC is most common type of eyelid skin cancer
Both rarely metastasize and both eventually bleed & ulcerate (more often in SCC)
13.
Which of the following treatment for skin lesions produces the lowest recurrence rate?
Correct Answer
D. Mohs Surgery
Explanation
Surgical excision: take out surrounding tissue too
Cryosurgery: liquid nitrogen
Radiation: preserves surrounding area
Mohs: remove by thin layers, time consuming, good for lesions that may recur (BCC/SCC)
14.
Ocular Pemphigoid is an autoimmune disease.
Correct Answer
A. True
Explanation
Antibodies bind to the conjunctival basement membrane --> inflammation --> scarring --> entropion & trichiasis
15.
Indicate the 3 signs that are part of the triad for menangiomas
Correct Answer(s)
A. VF loss from optic atropHy
B. Pallor
C. Optociliary shunt
Explanation
optociliary shunt is vaculature from the retina to the choroid, they are thicker vessels and more tortuous (vs neo which is thinner)
16.
Your elderly pt comes in for a check up. While performing SLE you notice a build up of tissue in the limbal region. You are not sure if its a notmal changes due to age or something potentially more serious. You decide to stain with Rose Bengal and you note diffuse staining around the lesion and the adjacent cornea. Your differential diagnosis at this point is:
Correct Answer
C. Conjunctival Intraepithelial Neoplasia
Explanation
CIN & ping look similar but here are differences:
- Ping is N/T so if you see S/I consider more serious Dx
- Ping usually bilateral
- Ping does not stain w/ RB
- Ping has 'dragged vessels' and CIN has more clustered vessels
- CIN is pre-malignant and is a pre-cursor to SCC
17.
What does CIGMA stand for in regard to etiologies of necrotizing scleritis?
18.
The main difference between scleromalacia perforans and necrotizing scleritis is that in scleromalacia there is NO inflammation
Correct Answer
A. True
Explanation
Tx:
Necrotizing scleritis - oral NSAID 1 week --> systemic steroids --> IV steroids or immunosupp
Scleromalacia - tx underlying condition (almost always RA)
19.
Which of the following would you see if you stained a herpes simplex dendrite with RB & NaFl?
Correct Answer
B. NaFl stains middle, RB stains outside
Explanation
Opposite for Zoster: RB stains middle & NaFl stains outside
**For Simplex, if you only use RB it will stain the entire dendrite
Simplex: Mercedes sign, disciform keratitis, Wessely immune ring, necrotizing keratitis, ghost dendrite
