Form of strabismus in which one or both eyes turn outward
What is Exotropia?
Common condition in which small specks, squiggly lines, or hair-like strands appear in the field of vision due to the shrinkage and detachment of collage fibers in the vitreous humor
What is Vitreous Floaters?
Benign tumor arising from the auditory nerve (the main nerve that leads from the inner ear to the brain)
What is Acoustic Neuroma?
A cyst in the middle ear consisting of skin cells and cerumen, or earwax
What is Cholesteatoma?
Loss of the ability to hear
What is Deafness?
Condition in which a defect (usually and elongated eyeball shape) results in light rays focusing in front of the retina rather than directly on it; causes distant images to appear blurry
What is Myopia?
Hyperopia (farsightedness) caused by an age-related reduction of elasticity in the lens
What is Presbyopia?
Emergency condition in which the retina separates from the layer of blood vessels that supports it. Common symptoms include floaters (small pecks, squiggly lines, or hair-like strands in the field of vision), flashing lights, and a shadow that gradually obscures vision.
What is Retinal Detachment?
Misalignment of the eyes caused by weakened eye muscles; crossed eyes
What is Strabismus?
Form of strabismus in which one or both eyes turn inward
What is Estropia?
Progressive, usually age-related, deterioration of the macula that leads to vision loss
What is Macular Degeneration?
Repetitive, usually involuntary movements of one or both eyes that results in limited visual acuity
What is Nystagmus?
Any of multiple disorders in which an irregularly shaped cornea or lens does not allow light rays to focus properly on the retina, resulting in blurred vision
What is Refractive Disorders?
Defective curvature of the cornea that produces blurred vision; may be present with nearsightedness or farsightedness
What is Astigmatism?
Condition in which a defect (usually a shortened eyeball shape) results in light rays focusing behind the retina rather than directly on it; causes images up close to appear blurry
What is Hyperopia?
A complication of diabetes marked by damage to the retina that can result in loss of vision
What is Diabetic Retinopathy?
Eversion (turning outward) of the eyelid (typically the lower lid), which often leads to redness, pain, and corneal breakdown
What is Ectropion?
Inversio (turning inward) of the eyelid, causing the eyelashes to irritate the surface of the eye; can potentially cause corneal abrasion
What is Entropion?
Disease in which intraocular pressure (pressure with the eyeball) causes damage to the retina and the optical nerve, eventually producing blindness
What is Glaucoma?
Purulent (pus-producing) inflammation of an eyelid gland commonly known as sty
What is Hordeolum?
Impaired vision in one or both eyes resulting from altered development in early childhood
What is Amblyopia?
Inflammation of the eyelid, resulting in redness, swelling, and crusting along the eyelid
What is Blepharitis?
Clouding of the lens that results in decreased visual acuity; caused by accumulation of protein in the lens
What is Cataract?
A small, hard, Cystic mass on the eyelid caused by a blocked oil gland
What is Chalazion?
Blockage, inflammation, and infection of a nasolacrimal duct and lacrimal sac
What is dacryocystitis?
