________ conjunctivitis is characterized by itching, tearing, redness and associated with hayfever.

Back 3

Allergic Conjunctivitis

Front 4

This is an increase in the pressure of the eye that can cause a temporary or permanent impairment in vision resulting from degenerative changes in the retina and optic nerve relating to edema.

Back 4

Glaucoma

Front 5

What form of Glaucoma is the most common?

Back 5

Open Angle Glaucoma

Front 6

_____ angle glaucoma is due to an abnormal increase in intraocular pressure but there is no obstruciton of iridocornial angle. It is asymptomatic with progressive damage.

Back 6

Open Angle Glaucoma

Front 7

This is due to occlusion of anterior chamber by the iris and is usually due to an anatomic defect that causes a shallow anterior chamber.

Back 7

Closed Angle Glaucoma

Front 8

Back 12

Retinopathy

Front 13

There are 2 types of retinopathies, difine them.

Back 13

Nonproliferative-confined to the retina; Proliferative-more severe and not confined to the retina

Front 14

Myopia, cataract extraction, conditions that lead to preretinal fibrosis, and exudate between the layers of the retina are predisposing factors for what?

Back 14

Retinal Detachment

Front 15

What is retinal detachment?

Back 15

Seperation of sensory retina from the pigment epithelium.

Front 16

This is characterized by loss of central vision due to destructive changes of the yellow-pigmented area surrounding the central fovea.

Back 16

Macular Degeneration

Front 17

This is the most common cause of reduced vision in the U.S.

Back 17

Macular Degeneration

Front 18

Differentiate between Otitis Externa and Otitis Media.

Back 18

WooHoo, we rock!

Front 19

This is when stimuli is not adequately transmitted through the canal to the inner ear.

Back 19

Conductive Hearing Loss

Front 20

What causes conductive hearing loss?

Back 20

impacted wax, otitis externa/media, and tumors

Front 21

This is due to a disorder of the inner ear; auditory nerve or auditory pathway of the brain, characterized by a decrease in the transfer of information.

Back 21

Sensorineural Hearing Loss

Front 22

What causes sensorineural hearing loss?

Back 22

Trauma, Thrombosis, and Hemorrhage

Front 23

What is spontaneous nystagmus?

Back 23

Uncontrollable movement of the eye.

Front 24

this is mainly a disorder of the peripheral vestibular disorder.

Back 24

Vertigo

Front 25

This is sensing movement once movement has stopped.

Back 25

Motion Sickness

Front 26

this si a disorder of the inner ear that can include pallor, sweating, nausea and vomiting, hearing loss, virtigo, and tinnitus. Unknown etiology but a possible viral link.
