Compose a short (1.5 – 2.5 page) essay explaining one common
alteration in vision and one common alteration in hearing. You
should briefly describe the pathophysiologic changes, prevalence,
manifestations, and treatment for each. You should also explain the
mechanism that the specific treatment uses to return a normal
functioning state. You may select a disease process from the book,
but will need to use additional resources to provide all the
information required for the essay.
