The corner of the eye, especially the inner corner near the bridge of the nose, is home to the lacrimal punctum – the opening that drains tears from the eye's surface into the nose. If this area experiences prolonged itching, accompanied by redness or discharge, individuals should not take it lightly.

Conjunctivitis

According to Medical News Today, conjunctivitis (pink eye) is a common cause of itching at the corner of the eye. This condition occurs when the conjunctiva (the thin membrane covering the white part of the eye and the inner surface of the eyelids) becomes inflamed. Besides itching, individuals may experience symptoms like red eyes, watery eyes, swollen eyelids, and discharge.

Conjunctivitis can stem from allergies, viruses, or bacteria. Allergic conjunctivitis often arises when eyes encounter pollen, dust, pet dander, mold, or other irritants. Avoiding contact with allergens, using artificial tears or eye drops, and taking antihistamines as directed by a doctor can help alleviate symptoms.

If the cause is viral or bacterial, the condition is contagious. Individuals should wash their hands frequently, avoid rubbing their eyes, and not share towels to prevent transmission.

Dry Eyes

Dry eyes are another common cause of itching, grittiness, or burning sensations at the eye corner. According to Healthline, this condition occurs when the eyes do not produce enough tears or when tear quality is poor, leading to inadequate lubrication of the eyeball surface. Individuals often report feeling as if there is a foreign object in their eye, experiencing burning, intermittent blurred vision, or excessive reflex tearing.

Prolonged dry eyes can damage the corneal surface and affect vision if left untreated. To improve symptoms, consider using preservative-free artificial tears, warm compresses, gentle eyelid massage, or medication as prescribed by a doctor. Blinking frequently when working on a computer, increasing room humidity, and wearing sunglasses outdoors are also recommended.

Lacrimal Duct Infection

Itching at the corner of the eye, particularly the inner corner near the nose, can also indicate a lacrimal duct infection (dacryocystitis). This condition arises when the tear duct becomes blocked, preventing tears from draining and creating an environment for bacteria to grow. Potential causes include sinusitis, a common cold, or a pre-existing tear duct obstruction.

Beyond itching, individuals may experience painful swelling in the inner eye corner area, continuous tearing, discharge, and even fever.

Lacrimal duct infections typically require antibiotic treatment. If infections recur frequently or if the tear duct remains persistently narrowed, individuals may need intervention to clear the tear drainage pathway.

Itching at the eye corner is usually not serious if it's transient, caused by dust or mild allergies. However, it is advisable to visit an eye care specialist if symptoms persist for more than 1-2 weeks or worsen, or if accompanied by significant eye redness, pain, swelling, or excessive discharge. Correctly identifying the cause ensures effective treatment and prevents complications that could affect vision.
