Chapter 33b: Flashcards

Intraocular pressure (IOP) measurement of pressure in the eye, usually <21 mm Hg. Increases in IOP can lead to glaucoma or blindness	Iris the colored part of the eye	Macula focal point on the retina that allows for clear, sharp vision especially when focusing on tasks straight ahead
Miosis constriction of the pupil, allowing less light into the eye	Mydriasis enlargement of the pupil, allowing more light into the eye. Commonly done for some eye examination procedures	Ocular hypertension an increase in intraocular pressure, which may lead to glaucoma in some patients
Pupil dark space in the middle of the iris that appears black. It widens and narrows to allow varying amounts of light into the eye	Retina lining in the back of the eyeball that allows light messages to be transmitted to the optic nerve and then the brain	Sclera white, outer part of the eyeball
