Sight: warning signs in the eyes may indicate diabetes or liver disease

The eyes are the window to the soul and are also powerful indicators related to health. A number of symptoms and changes can occur indicating that something is not quite right.

Autoimmune conditions

There are many types of autoimmune diseases that can impact your vision.

“In many cases, eye problems are among the first symptoms of autoimmune diseases,” Broberg Eye Care said.

The site added: “At first, patients may experience red eyes, itchy eyes, or frequent dry eyes.

If the condition is left undiagnosed or untreated, 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, which includes the brain and spinal cord.

Autoimmune diseases occur when the immune system malfunctions and attacks the body’s own tissues and organs.

Uveitis is another autoimmune disease that directly affects the pigmented cells of the iris of the eye, and sometimes also the middle layers of the eye.

It causes inflammation, which can lead to blurred vision, “floaters” and redness in the eye.


Diabetes can cause swelling of the macula, called diabetic macular edema.

Over time, this disease can destroy sharp vision 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.
