Unilateral Pericorneal Hyperemia In One Eye: Causes, Symptoms, And Treatment

What is Unilateral Pericorneal Hyperemia?

Unilateral pericorneal hyperemia, also known as unilateral pericorneal injection, is a condition characterized by redness and irritation in one eye. This condition can be caused by various factors, including infections, allergies, trauma, and underlying medical conditions. It is important to seek proper diagnosis and treatment from a healthcare professional to address the underlying cause and alleviate symptoms.

Pericorneal hyperemia refers to the redness of the blood vessels surrounding the cornea, which is the clear, dome-shaped surface that covers the front of the eye. When this redness and irritation occur in only one eye, it is considered unilateral. The affected eye may appear bloodshot, and the redness may extend from the edge of the cornea to the surrounding conjunctiva.

One of the common causes of unilateral pericorneal hyperemia is conjunctivitis, also known as pink eye. This highly contagious infection can be caused by viruses, bacteria, or allergens. According to the Centers for Disease Control and Prevention (CDC), viral conjunctivitis is the most common cause of pink eye, accounting for up to 80% of cases. Bacterial conjunctivitis is responsible for 50% of cases in children and 5-10% of cases in adults. Allergic conjunctivitis, on the other hand, is caused by exposure to allergens such as pollen, dust, or pet dander.

In addition to conjunctivitis, other infections such as keratitis (inflammation of the cornea) or uveitis (inflammation of the middle layer of the eye) can also lead to unilateral pericorneal hyperemia. These conditions may be caused by bacterial, viral, or fungal pathogens, and prompt diagnosis and treatment are essential to prevent complications and preserve vision.

Unilateral pericorneal hyperemia can also result from trauma or injury to the eye. Foreign bodies, chemical exposure, or blunt force trauma can cause irritation, redness, and inflammation in the affected eye. In some cases, underlying medical conditions such as dry eye syndrome, blepharitis (inflammation of the eyelids), or systemic diseases like rheumatoid arthritis or lupus may contribute to the development of pericorneal hyperemia.

It is crucial to seek evaluation and management from an eye care professional, such as an ophthalmologist or optometrist, if you experience unilateral pericorneal hyperemia. The healthcare provider will conduct a comprehensive eye examination to determine the underlying cause of the redness and irritation. This may involve assessing your medical history, performing visual acuity tests, examining the external and internal structures of the eye, and conducting additional diagnostic tests such as corneal staining, tear film evaluation, or intraocular pressure measurement.

Once the cause of unilateral pericorneal hyperemia is identified, appropriate treatment can be initiated. This may include the use of topical or oral medications to address infections, inflammation, or underlying medical conditions. In the case of allergic conjunctivitis, antihistamine eye drops or oral antihistamines may be prescribed to alleviate symptoms. It is important to follow the healthcare provider's recommendations and attend follow-up appointments to ensure proper healing and resolution of the condition.
