Ptosis is a condition of the eyelids often referred to as a "droopy eyelid." The muscles of the upper lid cannot pull tight enough, and, as a result, cannot lift the lid to a fully raised position. Due to the low position of the eyelid, ptosis may interfere with vision. Certain conditions, such as Bell's palsy, can cause ptosis, and doctors may recommend specific nutrients, such as vitamin B12, to treat this condition.
Causes
A common cause of ptosis occurs when the levitator muscles that control the eyelid separate or stretch, resulting in muscle laxity that droops the eyelid. If ptosis stems from muscle laxity, an eye surgeon can often repair the muscle, and, after a short period of healing, your eyelid muscles will raise your lids to a higher position. Muscle diseases, neurological disorders and certain types of tumors may cause ptosis as well. For these conditions, diagnosis may take time, and treatment may not quickly return the eyelid to a natural position.
Bell's Palsy
Bell's palsy is a condition that affects the nerves of your face, and this may result in muscle weakness or paralysis. A "droopy eyelid" commonly occurs with Bell's palsy, and, for some people, the eyelid remains in this position, without any control over opening and closing the eyelid. If you cannot close your eyelid, this may result in dry eye because the process of blinking coats the surface of your eye with nourishing tear film. You should frequently use artificial tears throughout the day, and use a thick ointment in your eye at night to prevent severe dryness that could lead to corneal scarring.
Vitamin B12 Treatment
In many cases of ptosis caused by Bell's palsy, treatment is limited to physical therapy, biofeedback, acupuncture and relaxation. Doctors may prescribe vitamin B12 in combination with vitamin B6 and zinc to help restore proper function, explains the National Institute of Neurological Disorders and Stroke. The amount of vitamin B12 you will require depends on the severity of the condition, additional medications you take and your overall health. Your doctor will help you determine a treatment plan that includes vitamin B12.
Considerations
If you notice a sudden change in the appearance of your eyelids, you should contact your doctor immediately because this could indicate a serious condition, such as a stroke. Do not start taking vitamin B12 for Bell's palsy or any other form of ptosis without first discussing your options with your doctor.
