Warning Signs That Your Red Eye Could Be Serious

Most of the time, a case of red eye is short-lived and disappears on its own. Sometimes, however, red eyes can be caused by a more serious condition. The following danger symptoms in a red eye should be evaluated by a medical professional.

Blurry vision is often associated with serious ocular disease. If your eye is red and your vision is blurry, something significant is going on. You need an evaluation to determine what is causing both symptoms.

When your doctor checks your vision, even during a routine eye exam, it is a simple, quick way to determine the health of the eye. If a patient can read the 20/20 line on the eye chart with ease, that at least tells the doctor that light is being focused on the retina fairly accurately and the retina is processing the information correctly. If your vision is blurry without associated redness, then it may be that you need vision correction or an update of your corrective prescription.

Conjunctivitis may produce mild irritation or scratchiness, but not extreme pain. Severe pain is a symptom of keratitis, a corneal ulcer, iridocyclitis, or acute open-angle glaucoma.

Photophobia, or extreme sensitivity to light, is usually a symptom of iritis. Iritis is an inflammatory disorder of the eye in which the ciliary muscle becomes inflamed and begins to spasm, causing the eye to feel sensitive to light. Light sensitivity is also a general symptom that occurs when the cornea is irritated. A corneal abrasion or corneal ulcer can bring on debilitating light sensitivity.

Colored halos are a symptom of corneal edema and acute open-angle glaucoma. Usually, halos seen around lights are caused by a disruption in the optical system of the eye. The cornea, the clear dome light structure on the front part of the eye, becomes thicker, due to the swelling, or edema. As it thickens, it also becomes cloudy. When this occurs, light scatters and we see halos.

If you think you may have one of the warning symptoms with red eye, it is important to see a medical professional.
