s a disease of the retinal microvasculature characterized by increased
vessel permeability. Blood and lipid leakage leads to macular edema and
hard exudates (composed of lipids). In advanced disease, new fragile
blood vessels form that hemorrhage easily. Because of the vascular and
cellular changes accompanying diabetes, there is often rapid worsening of
other pathologic vision conditions as well.

defines Disability as a multifaceted, complex experience that is
integrated into the lives of people with disabilities. The degree of the integration is influenced by
three disability-related factors:
(1) the effects of the disabling condition,
(2) others’ perceptions of disability, and
(3) the need for and use of resources by the person with a disability

The Americans With Disabilities Act of 1990 (ADA) defines a person with a disability as
one who:

A

(1) has a physical or mental impairment that substantially limits one or more major life
activities,

Characteristics of Chronic Conditions

A
  1. Managing chronic illness involves more than treating medical problems.
  2. Chronic conditions usually involve many different phases over the course of a person’s
    lifetime.
  3. Keeping chronic conditions under control requires persistent adherence to therapeutic
    regimens.
  4. One chronic disease can lead to the development of other chronic conditions.
  5. Chronic illness affects the entire family.
  6. The day-to-day management of illness is largely the responsibility of people with
    chronic disorders and their families.
  7. The management of chronic conditions is expensive.
  8. Chronic conditions raise difficult ethical issues for patients, families, health care
    professionals, and society.
  9. Living with chronic illness means living with uncertainty.
