VISISON DISORDERS- EXAM 2

GLAUCOMA

conditions that damage the optic nerve; increase IOP

NO CURE

-INCREASED PRESSURE IN THE EYE; OUTFLOW IS BLOCKED

black & asian/ CV disease/ diabetes/ nearsightedness/ sleep apnea/ prolonged corticosteroid use

TONOMOTRY

measure IOP needed to flatten cornea

OPTHALMOSCOPY

EXAMINE BACK OF THE EYE- ASSES OPTIC NERVE

GLAUCOMA ETC

THEIF OF SIGHT

-pts unaware until obvious signs of vision change

LIFELONG MANGEMENT

beta blockers/ cholinergic/ carbonic inhibitors/ prostaglandins

CATARACTS

leading cause of blindness

cloudiness of lens

-Painless, blurry vision

• No medications=prevention is best risk management

SURGERY

RETINAL DETACHEMENT

~EMERGENCY~ pts prone after to preserve gas bubble

“SHADE OR CURTAIN DRAPE OVER EYE”

-immediate surgery!

AMD-age related macular degeneration

BLURRED/ DARK VISION/ SCOTOMOTS: blind spot

Central Vision Affected

dry: slow breakdown of layers of Retina w/ drusen (NO CURE)

wet: acute onset; more damage proliferation of abnormal blood vessels under retina

OCULAR TRAUMA

CHEMICAL BURN: IRRIGATE WITH WATER AND SALINE

FOREIGN OBJECT: DO NOT REMOVE OJECT!!!! PROTECT, DONT COVER
