Document Summary
Eyes: test central visual acuity (refer to cnii-optic, test diagnostic visions test (refer to cniii-oculomotor, cniv-trochlear and cnvi-abducens, inspect external ocular structures (exclude eversion of upper lid and lacrimal apparatus, inspect anterior eyeball structures. Test for pupillary light reflex and accommodation (refer to cnii-optic and cniii-oculomotor: describe the purpose and function of the ophthalmoscope and test for the red reflex, identify critical findings related to sudden change vision. Ears: inspect and palpate external ear, describe the technique and rationale for otoscopic examinations. Describe the external canal and the tympanic membrane: test hearing acuity with whispered voice test (tests cnviii [acoustic]) Myopia (nearsightedness) with age, lens isn"t accommodating as well: change with vision- need to be assessed more often with age. Presbyopia (decrease in lens"s ability to change shape to accommodate for near vision)** Amblyopia (lazy eye) eye muscle that is weaker ie: turning in with the eye.
