Clear projections on the white eyeballs may be related to conjunctivitis, blepharospasm, and conjunctival lymphatic vessel blockage. 1. Conjunctivitis: Infection, allergy and other causes can cause inflammatory reaction of the conjunctiva, thus inducing edema of the conjunctiva, which looks like a transparent protrusion, and requires medical examination to make a clear diagnosis. 2. Blepharospasm: Blepharospasm often occurs on the bulbar conjunctiva on the nasal side of the cornea in the blepharospasm region, and sometimes grows in the temporal region as well. The formation of blepharospasm is related to external light, wind and sand stimulation, etc., and the incidence will be higher in areas with strong ultraviolet rays. Blepharospasm rarely invades the cornea, so it can be left untreated if there are no symptoms. 3. Conjunctival lymphatic vessel blockage: related to bad eye habits, inflammatory stimulation, etc. The blockage can cause round or vesicular bulging of the conjunctiva, which can be observed for a period of time when there is no obvious discomfort, and when accompanied by redness of the eyes, tearing and other discomforts, it can be intervened with medication or surgery. When there are transparent bulges on the white eyeballs, accompanied by eye redness, eye pain, increased secretion and other uncomfortable symptoms, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
