Study Notes
Eye Care and Abnormalities
- Regular eye examinations are recommended every 3-5 years for people under 40, and every 2 years after 40.
- Eye examinations assess external structures, visual acuity, ocular movement, and visual fields.
- Refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and presbyopia (loss of elasticity of the lens).
- Presbyopia begins around 45 years of age, causing difficulty reading newsprint.
- Bifocals are used to correct both far and near vision.
- Ptosis is a droopy eyelid, often associated with aging, edema, or systemic diseases.
- Ectropion and entropion are abnormalities of the eyelid, often due to scarring injuries or aging.
Pupils and Iris
- Normal pupils are black, equal in size (3-7 mm), and have round, smooth borders.
- Cloudy pupils may indicate cataracts.
- Mydriasis (enlarged pupils) may indicate injury, glaucoma, or certain drugs.
- Miosis (constricted pupils) may indicate inflammation of the iris, certain drugs, or age-related change.
Hearing and Abnormalities
- Audiometric evaluations are recommended for children and older adults.
- Conductive hearing loss occurs when sound waves are interrupted in the outer and middle ear.
- Sensorineural hearing loss is due to damage to the inner ear, auditory nerve, or brain.
- Mixed hearing loss is a combination of conduction and sensorineural loss.
- Weber's Test and the Rinne Test assess conduction hearing loss, sensorineural hearing loss, and nerve conduction or inner ear function.
Eyes and Ears Abnormalities
- Cataracts occur in individuals over 65, but can occur at any age, causing opacity of the lens or its capsule.
- Glaucoma is a disturbance in aqueous fluid circulation, causing increased intraocular pressure and potential blindness.
- Danger signs of glaucoma include blurred vision, loss of peripheral vision, and difficulty focusing.
- Abnormalities of the external ear and ear canal include infections, abnormal growths, and buildup of cerumen.
- Abnormalities of the tympanic membrane, such as acute otitis media, can have serious consequences.
