4 Possible Unilateral Eyeball Swelling Causes

The list below shows results from the use of our quiz by Buoy users who experienced unilateral eyeball swelling. This list does not constitute medical advice and may not accurately represent what you have.

Irritated eye causing swelling

Chemosis is a sign of eye irritation. The outer surface of the eye can look like a blister, filled with water or fluid. It can occur from infection or allergies, or as in this case, from rubbing the eye.

Rarity: Ultra rare

Top Symptoms: swelling of the eye area, eye itch, eye redness, swollen whites of eyes

Symptoms that always occur with irritated eye causing swelling: swelling of the eye area

Urgency: Phone call or in-person visit

Viral conjunctivitis

Viral conjunctivitis, or pinkeye, is an inflammation of the clear membranes covering the eye. It causes redness, pain, and irritation of one or both eyes.

The viral form of conjunctivitis is very contagious because it is caused by the same viruses that cause influenza or the common cold. It is spread when an infected person coughs or sneezes, and then someone else inhales the virus from the droplets in the air.

Symptoms include a gritty, burning feeling in the eye; discharge or tears; swelling; itching; pink discoloration due to dilated blood vessels; and sensitivity to light.

Diagnosis is made through patient history, physical examination, and careful eye examination. Smears may be taken from the eye for testing.

Antibiotics only work against bacteria and cannot help against a viral illness, and so antibiotic eyedrops are not effective against viral conjunctivitis. Treatment includes easing the symptoms with eyedrops and warm or cool compresses over the eyes until the illness has run its course, which takes two to three weeks.

Rarity: Common

Top Symptoms: eye redness, eye itch, sensitivity to light, feeling of something in the eye, watery eye discharge

Symptoms that always occur with viral conjunctivitis: eye redness

Urgency: Self-treatment

Bacterial conjunctivitis

Bacterial conjunctivitis, or pinkeye, is an inflammation of the clear membranes covering the eye. It causes redness, pain, and irritation of one or both eyes.

Staphylococcus or streptococcus bacteria are often involved, and anything that brings bacteria to the eye can cause conjunctivitis. Touching the eyes with unwashed hands; sharing eye makeup, washcloths, or towels; or improperly cleaning contact lenses are common causes. The same bacteria that cause the sexually transmitted diseases chlamydia and gonorrhea can also cause conjunctivitis.

Most susceptible are children, but anyone can be affected.

Symptoms include a gritty, burning feeling in the eye; discharge or tears; swelling; itching; pink discoloration due to dilated blood vessels; and sensitivity to light.

Diagnosis is made through patient history, physical examination, and careful eye examination. Smears may be taken from the eye for testing.

Treatment involves a course of antibiotic eyedrops. It is important to use all of the drops as prescribed, even when the infection seems to improve. Warm compresses over the eyes can help ease the discomfort.

Rarity: Common

Top Symptoms: sore throat, eye redness, eye itch, watery eye discharge, eye redness

Symptoms that always occur with bacterial conjunctivitis: eye redness

Urgency: Primary care doctor

Burst blood vessel in the eye from trauma

A burst blood vessel in the eye can happen after trauma to the eye or the head, which causes a surface vein to pop.

Rarity: Uncommon

Top Symptoms: eye redness, head or face injury, bright red eyes

Symptoms that always occur with burst blood vessel in the eye from trauma: eye redness, head or face injury

Urgency: Wait and watch
