Low Vision And Long Term Effects
The long term effects of low vision have become a piece in setting up treatment interventions with older patients. The most common causes of visual problems are macular degeneration, glaucoma, diabetic retinopathy and cataracts. Each causes a different problem in vision field deficit from macular degeneration, peripheral field deficit from glaucoma, central and peripheral field deficits from diabetic retinopathy and decreased contrast sensitivity from cataracts.
The most common areas that would be affected by low vision: self care; meal preparation and eating; money management; leisure activities; transfers and walking; and medication management. Once you have a client with low vision, you should recommend that the patient go for a visit with their eye care professional. You can also make a referral to a low vision therapist if there is one available in your company or in the region.
Next, try changing the environment to enhance vision performance. This can be done by making the items such as text larger through the use of low vision products or by purchasing special products for macular degeneration. Sometimes just increasing the lighting source can also help to see the item better.
Eliminating glare or providing greater contrast may help. For example, blue pills on a blue plate can be difficult to see, but placing blue pills on a white plate will be easier to find.
How to get more information - Ask your Eye MD for a Low vision Specialist. Low vision specialists are licensed doctors of optometry who are trained in the examination and management of patients with visual impairments. A few of them are ophthalmologists with additional training in low vision care. Their services do not offer a cure for the causes of low vision, but they do help the patient learn how to utilize their remaining vision to its fullest potential. Low vision care does not replace the possible need for other treatments such as laser, medication, and surgery.
What are low vision aids - The most common low vision aid for reading is called a Desktop Video Magnifier. These low vision products feature a camera mounted over a tray on which the material to be magnified is placed. Some have a built-in monitor and are known as "stand-alone" magnifiers. Others are designed to connect to a television or personal computer.
