Why Is My Vision Blurry?: Age-Related Eye Changes

This interrupted case study is based on the true experiences of the author's mother, who is referred to in the story as "Mrs. Horton" for reasons of privacy. Mrs. Horton, like many seniors, had her life altered due to age-related vision changes. As students work through the case, they will learn about vision and structural changes, as well as treatment and prognosis for presbyopia, cataracts, glaucoma, diabetic retinopathy, and age-related macular degeneration. In addition, shingles of the cornea and age-related glandular dysfunctions leading to dry eye and blurry vision will be investigated. In order to understand these and other age-related vision disorders, previous knowledge of the anatomy of the eye and its accessory structures is necessary. This case study was originally designed for a two-semester, freshman anatomy and physiology course. It is also appropriate for a sophomore pathophysiology course, especially if the student population will be working with seniors in the future. Other possible courses include aging, gerontology, and nursing.
