eyelid

swelling of the optic disc, visible upon ophthalmoscopic examination of the interior of the eye

softening of the lens of the eye

abnormal sensitivity to light, espcially by the eyes

loss of accommodation for near vision; poor near-vision due to the natural aging process

pertaining to the pupil

disease of the retina

excision of a portion of the sclear of the eye

acute or chronic inflammation of the yelid margins stemming from seborrheic allergic, or bacterial origin

a cyst or nodule on the eyelid, resulting from an obstruction of a meibomian gland, which is responsible for lubricating the margin of the eyelid

abnormal protursio of the eyeballs, usually with the sclera noticeable over the iris

ocular disorders identified as a group due to the increase in intraocular pressure

bacterial infection of an eyelash or sebaceous gland originating with redness, swelling, and mild tenderness in the margin of the eyelash

refractive error; lens of the eye cannot focus on an image accurately, resulting in impaired close vision that is blured due to the light rays being focused behind the retina because the eyeball is shorter than normal; far-sighted
