No body system operates independently and morbid disease or chronic illness can affect multiple systems. Systemic illnesses often impact eye health, and many of the most common medical conditions today can affect your vision.


Uncontrolled diabetes can have systemic implications, causing damage to multiple body organs and systems, including your eyes. Frequent highs and lows in your blood sugar can lead to a variety of vision issues, including cataracts, glaucoma, and retinopathy. Among the most common is retinopathy which affects the blood vessels of the retina negatively. Though it will never be noticed at first, it will most likely lead to vision loss in both eyes. According to Calgary optometry clinic Eyeconx, it is recommended that anyone diagnosed with diabetes should seek out an eye exam to measure their personal risk level. This could go a long way in preventing vision loss.

High Blood Pressure

Hypertension or high blood pressure which is caught early and effectively controlled can often have few to any lasting or serious affects. Uncontrolled hypertension will worsen with time and have progressively more series results, including serious implications for your vision. Advanced hypertension can lead to conditions like retinopathy, glaucoma, and macular degeneration. In the most severe cases, hypertension can cause swelling in the optic nerve and blindness.

Autoimmune Disorders

Diabetes, psoriasis, and other common, chronic illnesses are autoimmune in nature, meaning the body's own immune system fights against healthy cells and metabolic processes. Many other forms of autoimmune disorders can also affect your eyes, including lupus, rheumatoid arthritis, Sjogren's syndrome, multiple sclerosis, and myasthenia gravis, among others. Each of these conditions can affect the function of your eyes as well as your vision, and the symptoms can range from mild to severe, including everything from chronic dry eyes and drooping eyelids to ulcerative keratitis and optic neuropathy.

Chrone's Disease and Colitis

About 10 percent of those who suffer from Chrone's disease and colitis experience eye symptoms. In fact, vision issues and changes in the appearance and function of the eyes are sometimes among the first symptoms of inflammatory bowel disease (IBD). IBD, and certain medications that are used to treat it, can lead to episcleritis, uveitis, and keratopathyis as well as chronic dry eyes and inflammation, including inflammation in the optic nerve and retina. Most of these eye problems are treatable and have no lasting implications on visual ability, provided proper treatment is sought and followed.

Chronic illnesses and morbid disease often have implication for your vision as well as the function of your eyelids, tear ducts, optic nerves, and the muscles that control your eyes. In many cases, proper diagnosis and treatment of an underlying medical condition can resolve or at least control the eye symptoms you experience and potentially slow the loss of vision as well. Maintaining a healthy body weight, proper diet, and active lifestyle can prevent many chronic health conditions and can help control conditions like diabetes and high blood pressure.
