pressure equalizing tube (a tube that allows for draining the eardrum to prevent recurrent episodes of acute otitis media

SOM

Serous Otitis Media

AOM

Acute Otitis Media

Astigmatism

defective curvature of the cornea or lens of the eyes, which causes uneven or distorted images

hyperopia/hypermetropia (farsightendness)

unable to see things clearly, especially if they are close up

myopia (nearsightedness)

unable to see things clearly when they are far away

presbyopia

impairment of vision as a result of old age

cataract

clouding of the lens, or opaque glass like over the lens which blurs the vision and doesnt let light pass through- can be born with it or due to another illnesses occur- surgery or medication can help with this.

chalazion

small hard cystic mass/ granuloma on the eyelid due to chronic inflammation of the sebaceous gland

hordeolum/stye or sty

localized, purulent (consistent discharge of pus) due to an inflamed staph infection of a sebaceous oil producing gland in the eyelid- treatment: hot packs or surgery

diabetic retinopathy

retinal effects of diabetic mellitus are microaneurysms, hemorrhage of blood vessels, dilation of the retinal vein and neovascularization which cause vision loss in central vision of the eye

macular degeneration

progressive damage to the macular of the retina/ severe loss of central vision- treatment: increase in vitamins, eye drops to slow the process, or laser photocoagulation

nystagmus

repetative movements of one or both eyes

retinal detachment

2 layers of the retina separate from each other- usually due to trauma (head injuries, eye injuries, shrinkage of the vitreous humorous (causes holes or tears)

s/s: photopsia, floaters

treatment: photo coagulation (makes scar tissue over the tear), cryotherapy (freezer burn), or scleral buckle (silicone sutures)

photopsia

bright flashes of light

floaters

black spots or the object has a filmy shape

scleral buckle

silicone suture to bring the two tears together

strabismus/ abnormal deviation of the eye

failure of the eyes to look in the same direction because of weakness of the muscle controlling the position of one eye

esotropia

one eye turns inward or cross eyed

exotropia

one eye turns outwards: “wall eyed”

hypertropia

upward deviation of one eye

amblyopia

partial loss of vision from a “lazy eye”

diplopia

double vision

fluorescein angiography

intravenous injection of fluorescein (dye) followed by a series of photograph of the retina through dilated eyes

ophthalmoscopy

visual exam of the inter eye
