Chapter 10 : Drugs Used in Opthalmic and Otic Disorders Flashcards
Squinting of the eye
Blepharospasm
A waxy secretion of the glands of the external ear canal
Cerumen
Inflammation of the conjunctiva
Conjunctivitis
Paralysis of the ciliary muscle
Cycloplegia
Eyelashes emerge through the meibomian gland opening at the eyelid margin in a misdirected way, causing the eyelashes to touch and irritate the corneal surface
Distichia
A rolling outward or sagging of the eyelid
Ectropion
A rolling inward of the eyelid
Entropion
A group of eye diseases characterized by increased intraocular pressure that results in damage to the retina and optic nerve
Glaucoma
Paralysis of the sympathetic nerve supply to the eye that may cause enophthalmos, ptosis of the upper eyelid, slight elevation of the lower eyelid, constriction of the pupil, and narrowing of the palpebral tissue
Horner’s syndrome
A condition in which red blood cells are present in the anterior chamber of the eye
Hyphema
An injection into the anterior chamber of the eye
Intracameral injection
Inflammation of the cornea
Keratitis
Methicillin-resistant Staphylococcus aureus
MRSA
Dilation of the pupil
Mydriasis
A type of primary glaucoma of the eye in which the angle of the anterior chamber remains open, but filtration of the aqueous humor is gradually reduced, causing an increase in intraocular pressure
Open-angle glaucoma
Infestation of ear mites
Otoacariasis
The vascular layer of the eye that comprises the iris, ciliary body, and choroid
Uvea
Inflammation of the uvea
Uveitis
Abackwarddisplacementoftheeyeballintotheorbit
Enopthalmos
Drooping of the upper eyelid
Ptosis
Mydriatic agents are used to ____ the pupils
Dilate
Atropine is contraindicated in ____ and ____
Glaucoma, keratoconjunctivitis sicca
Miotic agents produce ____ constriction
Pupillary
Why are opthalmic stains used?
Ophthalmic stains are used as diagnostic aids for detecting disease in both the anterior and posterior segments and in the nasolacrimal system.
____ stain is the most commonly used dye for the detection of corneal epithelial deficits
Flyorescein
What type of administration is the most common method of treating disorders of the eye?
Topical opthalmics
Why do most topical opthalmic medications require several applications per day?
Because the eye secretes tears, the medication may be quickly diluted; thus reapplication becomes necessary.
What is Ophthaine used for?
To provide local anesthesia to the eye
Atropine ophthalmic agents are used to produce ____
Mydriasis
Epinephrine is contraindicated in ____ angle glaucoma
Closed
T/F Mannitol is a loop diuretic
FALSE
The local anesthesia provided by proparacaine HCL usually lasts ____ to ____ minutes
5 to 10
