A small white dot inside the eyelid may be a foreign body inside the eye that has not been removed in time, forming a residue that can be accompanied by a stinging sensation in the eye, a foreign body feeling, and other symptoms, which can generally be relieved by timely removal. If the white dots inside the eyelids are fixed and inactive, they may be caused by conjunctival stones, chalazion, wheals, or blockage of the lid gland opening.1. Conjunctival stones: Generally, chronic conjunctivitis leads to local inflammatory exudate and necrotic tissue buildup, which manifests as small white dots inside the eyelids. If the stone is small, it may not produce special sensation, if the stone is larger, it may produce foreign body sensation. They are usually treated with a history of bacterial or allergic conjunctivitis and can be relieved with topical antibiotic drops. 2. Chalazion: A small sterile cyst caused by blockage of the opening of the lid gland at the root of the hair follicle, also manifested as a small white spot inside the eyelid, usually at the base of the eyelashes. This can be treated with a warm towel and a localized hot compress on the eyelid to promote remission, or with the help of a doctor for surgical treatment of the chalazion. 3. This can be done with antibiotic drops such as cephalosporins for topical use or erythromycin for oral use. If pus is present, surgical incision is required to drain the pus. 4. Glucocorticoid drops and artificial tears are needed to help relieve the symptoms, and oral antibiotics are needed to help treat more severe symptoms. In addition, other eye diseases can cause small white dots on the eyelids, such as blepharitis and allergic conjunctivitis, which are relatively uncommon. If there are small white dots inside the eyelids, you can first exclude whether it is a foreign body residue in the eye, and then apply a local hot compress. If the symptoms do not ease or are accompanied by more obvious pain, you need to promptly seek medical attention for slit lamp and other related examinations, and under the guidance of an ophthalmologist for corresponding treatment.
