The reason for the symmetrical whitening of the inner corners of the two eyes may be due to dacryocystitis, blepharospasm, bulbar conjunctival swelling, etc. The specific cause should also be clarified under the guidance of the doctor through relevant examinations. 1. Dacryocystitis: when patients have bilateral dacryocystitis, under the stimulation of inflammation, ocular secretions can appear, and these secretions will flow out from the tear ducts, so that patients can show symmetrical whitening of the inner corners of the two eyes, and patients can follow the doctor’s instructions to use drugs such as levofloxacin eye drops for drug treatment. 2. Blepharospasm: Blepharospasm is a white plaque lesion formed due to prolonged direct sunlight, wind and sand stimulation and conjunctival tissue hyperplasia, so the patient will show symmetrical whitening of the inner corners of the two eyes. 3. Conjunctival swelling: when the patient’s conjunctiva is swollen in both eyes, it will also be manifested as a white bulge on the inner corners of the eyes, which will result in the whitening of the inner corners of both eyes. It is recommended that patients with symmetrical whitish lesions in the inner corners of the eyes and other discomforts should seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
