What eye drops can be used for itchy corners of the eyes?

Itching at the corner of the eye may require the use of eye drops depending on the specific underlying cause. In general, this symptom can be triggered by factors such as eye strain, environmental irritants, allergic conjunctivitis, bacterial conjunctivitis, or blepharitis. Individuals can improve their condition through appropriate measures such as general management or medication based on the specific situation. Detailed analysis is as follows:

1. Eye Strain

Prolonged screen time reduces blinking frequency, causing excessive tear evaporation and dryness of the ocular surface, which leads to itching at the corner of the eye. To relieve symptoms, take a 5-minute break every 40 minutes of screen use to look into the distance, apply warm compresses to the eyes, ensure adequate sleep, and reduce time spent using electronic devices.

2. Environmental Irritation

Exposure to wind, sand, dust, or ultraviolet (UV) radiation can irritate the ocular mucosa, leading to sensitivity and itching. Wear protective goggles when outdoors, avoid rubbing the eyes, rinse the eyes with normal saline, and maintain indoor air humidity.

3. Allergic Conjunctivitis

Eye itching at the corner may result from an immune response triggered by allergens such as pollen or dust mites, causing conjunctival redness, swelling, and discomfort. Under medical guidance, antiallergic eye drops such as olopatadine hydrochloride, sodium cromoglicate, or emedastine difumarate may be used. Additionally, avoid known allergens.

4. Bacterial Conjunctivitis

Bacterial infections (e.g., Staphylococcus) of the conjunctiva cause inflammation, resulting in itching at the corner of the eye along with increased eye discharge. Under medical supervision, antibiotic eye drops such as levofloxacin, tobramycin, or chloramphenicol may be prescribed. Maintain good eye hygiene and avoid sharing towels.

5. Blepharitis

Inflammation caused by bacterial infection or abnormal sebum secretion at the eyelid margin can lead to itching at the corner of the eye, accompanied by redness, swelling, and flaking along the eyelid edge. Treatment under medical guidance may include erythromycin eye ointment, tetracycline hydrocortisone ointment, or oral minocycline hydrochloride capsules. In severe cases, eyelid margin cleaning procedures may be required, along with regular eyelid hygiene.

Maintain good daily hygiene practices—avoid touching the eyes with dirty hands and regularly replace towels and pillowcases. Individuals with allergies should take preventive measures early and minimize exposure to allergens. Seek timely medical attention for any eye discomfort; do not self-medicate, as this may delay proper treatment or lead to adverse reactions.
