6 classes of glaucoma drugs with their cap colors
|
cholinergic agonists (GREEN)
adrenergic agonists (including alpha2) (PURPLE) Beta blockers (YELLOW) Carbonic anhydrase inhibitors-CAIs (ORANGE) prostaglandin analogs (White) hyperosmotic agents (n/a) |
|
|
Eye drop volume
|
20-50 microliters
|
|
|
Tear lake volume
|
7-10 microliters
|
|
|
Benzalkonium chloride (BAK)
|
preservative that allows drops to penetrate the corneal epithelium. Can cause corneal toxicity.
|
|
|
Pilocarpine
|
old school direct acting cholinergic, increases aqueous outflow stimulating CB contraction and opening of trab meshwork; also DECREASE uveoscleral outflow--which can increase IOP if trab is blocked; dosed TID or QID
|
|
|
Echothiophate iodide and carbachol
|
organophosphate AchE inhibitor (cholinergic); dosed BID
|
|
|
To what irido-corneal angle structure is the longitudinal muscle of the ciliary body attached
|
scleral spur (cholinergics cause contraction of longitudinal muscle and opening of the scleral spur)
|
|
|
What ocular effects of cholinergic agents do not affect IOP?
|
miosis (which can increase VA via PH effect) and accomodation (up to 15D in young pts)
|
|
|
Why is it sometimes helpful to increase pilocarpine in pts with dark irides?
|
pilocarpine is bound by uveal pigment
|
|
|
Ocusert
|
controlled-release pilocarpine inserted under lid
|
