Block 2 Flashcards
(301 cards)
What is the MOA of anti-allergy medications for the eye?
H1 receptor blocker
Anti-Cholinergic MOA + eye?
Inhibits glandular secretions
Beta blocker MOA + eye?
Non-selective MOA?
Reduces lysozyme lvls and IgA
Non-selective = reduces IOP by decreasing aqueous formation by ciliary body
What Rx causes band keratopathy?
Diuretics
What Rx causes vortex keratopathy?
Amiodarone + Chloroquine/Hydroxychloroquine
What are the side effects of Amiodarone + eye?
- Vision loss
- Pseudotumor cerebri
- Haloes
What is pseudotumor cerebri and what causes it?
Increased intracranial pressure leading to optic nerve swelling and eventually vision loss
- Amiodarone
What are the side effects of Digoxin + eye?
- Red/Green color defect
- Xanthopsia
- Flashes of light
- Reduces IOP
Digoxin MOA + eye?
Inhibits Na-K ATPase pump
What are some side effects of anticoagulants and antiplatelets and eye?
Subconjunctival and retinal hemorrhage
Chronic use = yellowing of vision
What are the side effects of Accutane + eye?
- Blepharoconjunctivitis
- Night blindness
- Contact lens intolerance
What drugs cause hyperpigmentation and dark deposits in palpebral conjunctiva?
Tetracyclines
Tetracyclines can cause what to the eye?
Hyperpigmentation and dark deposits in palpebral conjunctiva
What is blepharoconjunctivitis and what causes it?
Swelling of lids and conjunctiva
- Accutane
How would you manage tetracycline + eye issues?
d/c Rx
Oral steroids and/or diamox to reduce intracranial pressure
How would you manage amiodarone + eye issues?
Frequent eye exams (q6months), decrease dose or d/c Rx
What drugs have irreversible damages to the eye?
Chloroquine and Hydroxychloroquine
Maybe…Anti-tuberculosis Rx…?
Phosphodiesterase agents
How would you manage chloroquine/hydroxychloroquine + eye?
- Baseline testing before starting Rx, then annual exam
2. If toxicity is found, immediately d/c
Chloroquine/Hydroxychloroquine can cause what to the eye?
- Bulls-eye maculopathy
- Vortex keratopathy
- Ptosis
What specifically do chloroquine and hydroxychloroquine target in the eye?
High affinity to melanin and toxic to retina
What specifically do anti-tuberculosis Rx target in the eye?
Chelates copper
Decreased levels impair mitochondrial activity and leads to optic neuropathy
What specifically do anti-hyperglycemics target in the eye?
Activate PPAR-gamma which leads to fluid retention in retinal vasculature
Corticosteroids can cause what to the eye?
Cataracts (posterior lens opacity)
Increased IOP
+ Glaucoma
What drugs can cause macular edema?
Hyperglycemics
