Normal Aging structural changes of the Eye Correct Answer-1.
decreased eye muscle tone reduces ability to keep gaze focused on a
single object.
2. the lower eyelid may relax and fall away from eye leading to dry eye
symptoms
3. Arcus senilis - an opaque, bluish white ring within the outer edge of
the cornea, caused by fat deposits but does not effect vision
4. the shape of cornea changes, the cornea flattens and the curve of its
surface becomes irregular causing or worsening astigmatism and distorts
or blurs vision- *occurs after 65*
5. fatty deposits cause the sclera to develop a yellowish tinge, a bluish
color may be sen as the sclera thins.
6. the iris has less ability to dilate, which causes difficulty adapting in
dark environments, such as needing more light to read and more light
not to trip over things
normal aging functional changes of the eye Correct Answer-1. the lens
yellows reducing the ability of the eye to transmit and focus light
2. the lens hardens, shrinks, and loses elasticity which causes loss of the

3. Cerumen is dryer and impacts more easily, reducing hearing function
- irrigate canal weekly
4. Typanic membrane loses elasticity and may appear dull and retracted,
(do not use this finding as the only indication of otitis media in older
adults)
5. Hearing acuity decreases in some older adults, do not assume all older
adults have hearing loss
6. Ability to hear high-frequency sounds is lost first, may also have
problems with hearing "f, s, sh, and pa" sounds
