Sensory Impairment in Older Adults: Part 2: Vision Loss As adults age there is a persistent declination in age related eye degeneration. Many times this occurs naturally with age, but can also be a result of medical conditions found in older patients. A portion of these medical conditions include macular degeneration, cataracts, glaucoma, and diabetic retinopathy. These visual impairments can lead to a need for assistive devices depending on the severity of the disorder or disease. The study was done to pinpoint the causes of visual impairment among adults, whether from a condition or natural aging, in order to provide safer more effective care. In the American

There are two types of glaucoma; open ended and close ended glaucoma. Open ended glaucoma effects the trabecular meshwork and the schlemm canal found between the anterior chamber of the eye and the lens. In open ended glaucoma the Schlemm canal gets blocked with debris. In close-ended glaucoma the iris of the eye is blocked by the trabecular meshwork of the eye. Glaucoma leads to loss of peripheral vision. The buildup of debris leads to intraocular pressure, damaging the optic nerve. The damaging of the optic nerve is due to the result of aqueous fluid not being able to reach the drainage angle (schlemm canal) near the anterior chamber of the …show more content…
Diabetic retinopathy is caused by damage of the red blood vessels in the eye, causing leakage and overgrowth. According to AJN, this leads to scarred tissue in the eyes. The range of age for diabetic retinopathy is twenty to seventy-four years old. Retinopathy is one of the most frequent newer causes of blindness(AJN). Retinopathy is much similar to macular degeneration. In diabetic retinopathy there is also a sub retinal hemorrhage. However, there are abnormal vessels on the surface of the retina; as well as exudates. Exudates are yellow flecks caused by lipid residues of leakage from damaged
