Eyes can be an early sign of disease - from diabetes to a diseased liver. A number of symptoms and changes may occur, indicating that something may not be quite right.

Autoimmune Conditions There are many types of autoimmune diseases that can affect your vision..

" “At first, patients may experience redness of the eyes, itchy eyes, or frequent dry eyes.. If the condition is not diagnosed or treated, patients may experience eye pain, sensitivity to light, changes in the quality of vision, and even loss of vision."

Neuromyelitis optica is an autoimmune disease that affects the nerves of the eyes and the central nervous system, including the brain and spinal cord.. Autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs..

Rosacea Rosacea is a skin condition that causes redness in the face.. When rosacea is localized around the eyes, it can lead to dry eyes, itchy eyes, a burning sensation around the eyes, and redness of the eyes.. The condition can also lead to swelling of the eyelids and increased sensitivity to light..

Liver disease Jaundice (yellow whites of the eyes) often means you have liver problems and is caused by high levels of bilirubin, which your liver makes more when it's inflamed or damaged.

Diabetes Diabetes can lead to swelling of the macula called diabetic macular edema. Over time, this disease can destroy visual acuity in that part of the eye, leading to partial vision loss or blindness.. Macular edema usually develops in people who already have other signs of diabetic retinopathy.
