patho
_______ blocks some light from passing through the eyeball lens and scatters light, preventing all of it from reaching retina and thus preventing allowance of vision to be crisp and clear
cataracts

_________ angle glaucoma
- Abnormal angle between the iris and the cornea
- Outflow is blocked when the pupil is dilated
-
__________ angle glaucoma
- Abnormal/blockage of trabecular meshwork
- Reduced/slowed drainage of aqueous humor (eye ball juice)
- Imbalance between inflow and outflow
- Increased IOP and results in vision problems
Closed - AKA Acute angle closure glaucoma or narrow angle glaucoma
Open
2 types of _________________:
1. Dry – non-exudative (most common)
-Yellow deposits in the retinal pigment epithelium
2. Wet – exudative
-Growth of new leaky blood vessels in an abnormal location of the retina
Macular degeneration
MOA
- Blocks conversion of testosterone to DHT (alpha 1 receptors)
- Decreased epithelial tissue in prostate
Indications
- Mechanical obstruction of urethra
- Works on enlarged prostate only
s/e
- Impotence
- Decreased libido
- Gynecomastia – abnormal growth breast tissue
Other notes
- Results 6-12 mos
- Take it for life
- Lowers DHT, doesn’t lower testosterone
- Males can’t donate blood while taking this med
- Decreases prostate specific antigen (PSA) levels
o measure PSA before starting drug and 6 mos after starting drug
o If PSA isn’t low = eval for prostate cancer
- Also used to treat male pattern baldness – increases hair growth
- Females caution in handling – tetragenic for preg. Women, may cause birth defect in male fetus
Class: 5 alpha reductase inhibitors
Drug: finasteride

CKD
AKI =
- Oliguria (goal is >30ml/hr or <400ml/24hr)
- begins 1 day after hypotensive event and lasts 1-3 weeks
- FVE
- Metabolic acidosis and waste product accumulation (azotemia/uremia) – no excretion, build up of waste
- Hyponatremia – no excretion, dilution issue
- Hyperkalemia – no excretion, accumulation issue
- Neurologic disorders – r/t hyponatremia
- AKI can develop into CKD if pt doesn’t recover
Treatment of AKI or CKD

- Avoid nephrotoxic drugs
- Monitor for CKD problems
AKI
Manifestations
- Spontaneous, sudden
- Unilateral vision loss
- Painless
- Floaters

Retinal detachment
The glomerulus
Capillary membranes have 3 layers
1. Endothelium
2. _________ (where a lot of issues occur)
3. Podocytes – special epithelial cells
The glomerulus
Capillary membranes have 3 layers
1. Endothelium
2. GBM – glomerulus basement membrane (where a lot of issues occur)

BPH or testicular cancer?
s/s
testicle enlargement doesn’t correlate with severity of s/s
similar to UTI
- Frequency
- Urgency
- Delay
- Reduction in force
- Increased urination time
- Dribbling
LUTS
lower urinary tract symptoms
BPH
Drug: __________
MOA
- Blocks alpha 1 receptors – relaxes smooth muscle cells in bladder, neck, prostate, and urethra
