Intraocular pressure (IOP)

measurement of pressure in the eye, usually <21 mm Hg. Increases in IOP can lead to glaucoma or blindness [toggle]

Iris

the colored part of the eye [toggle]

Macula

focal point on the retina that allows for clear, sharp vision especially when focusing on tasks straight ahead [toggle]

Miosis

constriction of the pupil, allowing less light into the eye [toggle]

Mydriasis

enlargement of the pupil, allowing more light into the eye. Commonly done for some eye examination procedures [toggle]

Ocular hypertension

an increase in intraocular pressure, which may lead to glaucoma in some patients [toggle]

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 [toggle]

Retina

lining in the back of the eyeball that allows light messages to be transmitted to the optic nerve and then the brain [toggle]
