Red eye, which may occur due to various causes, can be an early sign of conditions that may lead to vision loss or even loss of the eye…

The term “red eye” is not a diagnosis in itself but a general expression used to describe a visible condition affecting the eye. The eye consists of multiple layers, including the ocular surface, the retina, and the uvea. Each of these layers may cause redness as a result of different diseases. Clinical conditions such as conjunctivitis, keratitis, uveitis, and increased intraocular pressure (glaucoma) are among the most common causes of red eye. In ocular surface diseases, the most frequent causes of red eye involve problems related to the eyelids, conjunctiva, cornea, and the tear system. Irritation, infection, inflammation, or functional disorders affecting these tissues may lead to pronounced redness and a sensation of discomfort in the eye. In this context, red eye can represent much more than a simple superficial redness, and early identification of the underlying condition is critical for appropriate treatment and referral.

Take Eye Redness Seriously
Eye redness may occur due to various causes, and treatment options can differ accordingly. If red eye develops suddenly and progressively worsens, it requires greater attention. The presence of pain alongside redness is an indicator of increased severity. When red eye occurs, it is essential to be evaluated by an ophthalmologist as soon as possible and to receive appropriate treatment. Many conditions that begin with red eye can result in vision loss or even loss of the eye if left untreated. In fact, in many patients presenting with red eye, systemic conditions such as rheumatic, hormonal, and dermatological diseases may also be diagnosed. Red eye is a condition that should never be underestimated. Using inappropriate medication instead of seeking professional eye care may not only be ineffective but can also lead to serious consequences.
