---|---|---|---|---|---|
Miosis | Contraction of the iris sphincter muscle, which causes the pupil to narrow
🗑
|
||||
Mydriasis | Contraction of the dilator muscle and relaxation of the sphincter muscle, which causes the pupil to dilate
🗑
|
||||
Open Angle Glaucoma | reduced outflow of aqueous humor through the trabecular network and Schlemm's canal because of resistance of the aqueous humor outflow; the iridocorneal angle is open.
🗑
|
||||
Closed/Narrow Angle Glaucoma | Sudden increase of IOP caused by mechanical obstruction of the trabecular network in the iridocoroneal angle.
🗑
|
||||
Osmotic agents (isosorbide/Ismotic)) | Reduces volume of intraocular fluid
🗑
|
||||
Carbonic Andhydrase Inhibitors (acetazolimide/Diamox) | Inhibit carbonic andhydrase resulting in a decrease in the production of aqueous humor, thus lowering IOP
🗑
|
||||
Cholinergic agents (pilocarpine/Isopto-carpine) | Produces strong contractions of the iris and ciliary body
🗑
|
||||
Cholinesterase Inhibitors (echothiophate iodide/Phospholine iodide) | Used when Cholinergic agents don't work. Prevents metabolism of acetylcholine resulting in increased cholinergic activity which decreases IOP.
🗑
|
||||
Adrenergic agents (phenylephrine/Neophrine; brimonidine/Alphagan P) | Cause pupil dilation, increased outflow of aqueous humor, vasconstriction, relaxation of ciliary muscle
🗑
|
||||
Beta-Adrenergic Blockers (timolol maleate/Timoptic) | Used to reduce IOP. They are thought to reduce the production of aqueous humor.
🗑
|
||||
Prostiglandin Agonists(latanoprost/Xatalan) OOG | Increases outflow of aqueous humor. May causee eye pigment changes
🗑
|
||||
Anticholinergic agents (atropine sulfate/Isopto-atropine) | Relax smooth muscle of the ciliary body and iris to produce mydriasis and cyclopegia.
🗑
|
||||
Antibiotics |
🗑
|
||||
Antifungal agents |
🗑
|
||||
Antiviral agents |

To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
