Small bubbles on top of the eyelashes are mainly caused by a blockage of the lid gland opening. Under normal circumstances, our lid glands secrete some oil-like substances that are discharged smoothly through the mouth of the lid gland and are evenly coated on the surface of the eye to lubricate the eye and keep the surface moist. When the lid gland is dysfunctional, the lid gland mouth is blocked and the secretions of the lid gland cannot be discharged normally, which over time leads to the formation of these small bubbles at the base of the eyelashes. In the early stages of the disease, you can use local hot compresses and also apply local antibiotic eye ointment to promote absorption; if it does not subside for a long time you need to make a local incision to drain the material inside and then apply antibiotic eye ointment for anti-inflammatory symptomatic treatment.
