Visual disturbances interfere with normal sight. The various types of visual disturbances may be caused by several conditions and disorders. Some are temporary and can be relieved with treatment. However, some can be permanent.

Causes of Visual Disturbances
-- Cataracts
-- Clouding of your eye’s lens
-- Corneal scarring or infections
-- Diabetes
-- Hypertension
-- Injury or irregularity on your eye’s lens and cornea
-- Muscle weakness
-- Nerve conditions, such as multiple sclerosis and Guillain-Barre syndrome

Treating Visual Disturbances
The first step in treating a visual disturbance is figuring out the underlying problem that is causing it. Once you and your doctor have discovered the problem, you can develop a plan for treatment. In some cases, the disturbance will go away naturally-blurry vision caused by a headache will usually resolve when the headache recedes. However, your doctor may wish to prescribe medicine to prevent future headaches or medicine you can take when a headache begins causing visual complications.

There are several common treatments for visual disturbances. Medication can treat underlying conditions so they no longer cause symptoms. Dietary changes can prevent visual disturbances in people with uncontrolled diabetes. Glasses, contact lenses, or magnifying devices may be able to correct vision disturbances that cannot be corrected with another treatment. If necessary, surgery can help relieve or repair damaged nerves and muscles.
