Macular Degeneration Pathophysiology: Macular degeneration refers to a deterioration of the macular area of the retina. Macular degeneration is caused by impaired blood supply to the macula that results in cellular waste accumulation and ischemia. Dry macular degeneration— the most common form— occurs when the blood vessels under the macula become thin and brittle. Wet macular degeneration – in this type, brittle vessels break down, and new, abnormal, fragile blood vessels grow under the macula (choroidal neovascularization). (Pathophysiology: A Practical Approach p. 444 -445). Expected Findings: Lack of depth perception, objects appear distorted, blurred vision, loss of central vison, blindness, haziness in vision (ATI RN MS Pg. 63) Risk factors: Dry: Age, smoking, hypertension, female, short body stature, family history, diet lacking carotene, and vitamin E. ; Wet: Can occur at any age.(ATI RN MS Pg. 63) Complications: Detached retina, legal blindness, depression, anxiety, deficit in independence, loss of income, social isolation.(Pearson vi

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
