A swollen eye can be caused by a number of things, including conditions such as allergies, hyperthyroidism and blepharitis. Allergies can be treated with medications for prevention and by learning what triggers symptoms, then avoiding or limiting exposure to the offenders. Blepahritis and hyperthyroidism may require a more intensive treatment plan, depending on the severity of the disorder. According to the Mayo Clinic, blepharitis may be difficult to treat and hypothyroidism may require surgery in some people.
Hyperthyroidism
Hyperthyroidism is the result of an overactive thyroid. The condition causes the thyroid gland to produce an excess of the hormone thyroxine. According to the Mayo Clinic, hyperthyroidism can accelerate the body's metabolism and cause sudden weight loss, sweating and nervousness, rapid heartbeat and irritability. Another rare symptom of hyperthyroidism is known as Graves' ophthalmopathy, a condition that affects the eyes by causing the eyeballs to protrude as tissues and muscles behind the eyes swell. Symptoms of this condition include red or swollen eyes, discomfort and tearing, sensitivity to light, vision disturbances such as blurry vision and protruding eyeballs.
Blepharitis
Blepharitis is a chronic eye condition affecting the skin of the eyelids (typically where the eyelashes grow). According to the Mayo Clinic, the condition is commonly caused by malfunctioning oil glands located near the base of the eyelashes. This leads to the overgrowth of bacteria, which causes the eyes to become itchy and irritated. Although the condition may be uncomfortable, no permanent damage to the eye is likely to result. Other symptoms of blepharitis include: burning sensations in the eye; itchy eyelids; watery, red and swollen eyes; sensitivity to light; crusts and flaking skin around the eyes; loss of lashes, and abnormal growth patterns of the lashes.
Allergies
According to an article reviewed by David Zieve, M.D. and medical director of A.D.A.M., Inc., allergies are a common result of an oversensitive immune system. This may cause the body to release chemicals called histamines, resulting in minor and severe symptoms. Genetics and environmental factors can play a role in allergies and can cause a host of exasperating symptoms such as sneezing, wheezing, coughing, hives, skin rashes and conjunctivitis. Conjunctivitis affects the eyes, leaving them red and swollen. Treatments for allergies can include over-the-counter medications, prescriptions and lifestyle changes, such as avoiding certain foods and other triggers. Eyedrops may provide relief for red and swollen eyes.
