Blepharitis
|
common inflammatory condition of the eyelids, lash follicles, and gland of the eye resulting in swelling, redness, and crusts of dried mucus
|
|
Conjunctivitis
|
Inflammation of the conjunctiva, sometimes called pinkeye
|
|
Dacrocystitis
|
common infection of the lacrimal sac caused by an obstruction of the nasolacrimal duct or by trauma
|
|
Keratitis
|
inflammation of the cornea, usually confined to one eye (may be acute or chronic, superficial or deep)
|
|
Cataract
|
common cause of vision loss where the lens or lens capsule of the eye develops an opaque layer
|
|
Corneal Abrasion
|
scratch on the surface epithelium of the cornea caused by a foreign body
|
|
Macular degeneration
|
atrophy or degeneration of the macular disk (most common cause of blindness in adults)
|
|
Nystagmus
|
recurring, involuntary eyeball movement that produces blurred vision and difficulty focusing. The movement can be horizontal, vertical, rotating, or mixed
|
|
Retinal detachment
|
retinal layers split and create a subretinal space which fills with subretinal fluid
|
|
Glaucoma
|
group of disorders characterized by an abnormally high IOP, which can damage the optic nerve. Without treatment a person can become blind.
|
|
Chronic Open Angle Glaucoma
|
overproduction of aqueous humor
|
|
Acute Angle or Closure Glaucoma
|
obstruction to the outflow of aqueous humor
|
|
Secondary Glaucoma
|
results from uveitis, trauma, or drugs such as steroids
|
|
Retinitis Pigmentosa
|
a genetic disorder causing progressive destruction of the retinal rods leading to eventual blindness
|
|
Vascular Retinopathies
|
non-inflammatory retinal disorders resulting from a disruption to the eye's blood supply. There are two types
|
|
Hypertensive Retinopathy
|
results from prolonged HBP that produces retinal vasospasm and consequently damages and narrows the arteriolar opening.
|
|
Diabetic Retinopathy
|
results from complications of diabetes mellitus
|
|
Bacitracin and Erythromycin
|
Anti-Infectives used to treat eye infections
|
|
Anti-inflammatory agents
like Dexamethasone |
used to treat inflammatory conditions of the eye
|
|
Artificial Tears
|
provide moisture for the eyes when tear production is an issue
|
|
A miotic
|
an agent that causes pupil constriction
|
|
A mydriatic
|
an agent that causes pupil dialtion
|
|
Opthalmic Anesthetics
|
prepares the eye for procedures, such as tonometry, suture removal of the cornea, or removal of foreign bodies.
|
|
Laser Surgery
|
lasers generate focused or monochromatic light waves that magnify their power by deflecting light waves off a series of mirrors resulting in a finely focused, high-energy beam.
|
|
Intracapsular Cataract Extraction
|
procedure where the entire lens is removed, most often with a cryoprobe (freezes and adheres to the lens making it easier to remove)
|
|
Extracapsular Cataract Extraction
|
procudure where the surgeon removes the patient's anterior capsule, cortex, and nucleus, leaving the posterior capsule intact (this technique used irrigation and aspiration)
|
|
Iridectomy
|
making a hole in the iris to create an opening for the aqueous humor to bypass the pupil, this reduces the IOP by improving drainage
|
|
Radial Keratotomy
|
treatment for myopia (near-sightedness) that involves the creation of small radial incisions in the cornea. This flattens the cornea and help focus light on the retina
|
|
Sclerectomy
|
excision of part of the sclera
|
|
Scleral Buckling
|
Surgical repair of a detached retina
|
|
Trabeculectomy
(Tra-bic-u-lectomy) |
removes part of the trabecular meshwork, allowing aqueous humor to by-pass blocked channels
|
|
Vitrectomy
|
microsurgical procedure to remove all or part of the vitreous humor, the gelatinous transparent substance that fills the cavity behind the lens
|
|
Corneal Transplant
|
uses healthy corneal tissue to replace a damaged portion of the cornea
|
|
Full Thickness Penetrating Keratoplasty
|
excision and replacement of the entire cornea
|
|
Lamellar Keratoplasty
|
removal and replacement of superficial layers of corneal tissue
|
