Study Notes
Week 3 Notes: Eyes and Ears Assessment
- Eye Review: External anatomy includes eyelids, conjunctiva, lacrimal apparatus, extraocular muscles, sclera, and cornea. Internal anatomy contains three layers: outer (sclera and cornea), middle (choroid, ciliary body, and iris), and inner (retina).
- Ocular History: Questions should address vision difficulties, pain, redness, swelling, discharge, history of ocular problems, glaucoma, use of corrective lenses, and self-care behaviors.
- Eye Assessment: Tests for central visual acuity (Snellen chart), visual fields (confrontation test), extraocular muscle function (corneal light reflex, cover-uncover, and diagnostic positions), external structures (eyelid, lashes, conjunctiva, sclera), anterior eyeball structures (cornea, lens, iris, pupil), and ocular fundus (optic disc, retinal vessels, macula).
- Cranial Nerves for Vision: Cranial nerves associated with eye assessment include II (Optic – vision), III (Oculomotor – eyelid movement, pupil constriction, most extraocular movements), IV (Trochlear – downward and inward eye movement), and VI (Abducens – lateral eye movement).
- Age-Related Eye Changes: Infants are born with peripheral vision intact, and the macula fully develops by 8 months. Older adults experience presbyopia (lens loses elasticity), cataracts, macular degeneration, and decreased tear production.
- Ear Anatomy Review: The external ear consists of the auricle and external auditory canal. The middle ear includes the tympanic membrane, ossicles (malleus, incus, stapes), and Eustachian tube. The inner ear contains the vestibule, semicircular canals, and cochlea.
- Hearing Loss Types: Conductive hearing loss is caused by blockage in the external or middle ear (e.g., impacted wax, otitis media). Sensorineural hearing loss results from inner ear or cranial nerve VIII damage (e.g., aging, noise exposure).
- Ear Assessment History: Questions should address hearing loss, pain, discharge, tinnitus, vertigo, infections, and exposure to noise.
- Ear Testing: The assessment includes inspecting the external ear (size, shape, lesions, tenderness), using an otoscope to examine the tympanic membrane and ear canal (for abnormalities), performing hearing tests (whisper test, tuning fork tests – Weber and Rinne), and testing for hearing acuity.
- Cranial Nerves for Hearing: Cranial nerve VIII (Vestibulocochlear) is responsible for hearing and balance.
- Age-Related Ear Changes: Infants have shorter, more horizontally oriented Eustachian tubes, increasing infection risk. Older adults experience cerumen impaction, presbycusis (age-related hearing loss), and decreased acuity.
