agents
3. Astringents Are applied to help precipitate proteins, used for areas of moist dermatitis
4. Schrimer Tear measures the amount of tears produced by the lacrimal (tear) glands. - used to
Test dx KCS(Dry Eye)
5. Phenol Red Also used to evaluate tear production, dx dry eye
Thread
6. Fluorescein stain Checks to see if the cornea is intact or an ulcer is present.
7. Corneal Ulcer Abrasion of the corneal caused by infection or injury. Must be treated promptly
to avoid rupture of the eye.
8. Rose Bengal is a stain used to detect corneal damage due to viruses or low tear production (dry
eye).
9. Intraocular pres- used to check pressure of the eye - high pressure is dangerous and must be
sure measure- treated to prevent blindness.

10. Topical Anesthet- drops can be used to numb an eye to check for and remove a foreign body from
ic drops the eye. Includes proparacaine and tetracaine.
11. Povidone Iodine can be used as an antiseptic to remove dirt and debris from an eye and to clean
solution the surface of an eye before sugery - must be diluted.
12. eye drops easier to apply but larger portion of the medication is removed from the eye within
a short period of time. About 90% will end up on the face once the animal blinks.
13. eye ointments can be harder to apply, last longer, often treatment is more affective.

phenylephrine - makes it easier to see the back of the eye during a ocular exam.
15. Cycloplegics help paralyze the ciliary muscle, which reduces pain in the eye.
16. Miotics constrict (close) the pupils. These drugs are used to help treat glaucoma. Drug
most frequently used is topical pilocarpine, also included Bromide and Carbachol

18. How can IOP be by decreasing the production of aqueous humor. Carbonic anhydrase inhibitors
controlled? lower the production of aqueous humor, which lowers the pressure in the eye.
19. Drugs used to Topically (dorzolamide)

Intravenously (acetazolamide)
