White blisters growing in the white bulb of the eye are most commonly seen in ophthalmologic clinics as bulbar conjunctival edema, conjunctival cysts, and lymphadenopathy. 1. Bulbar conjunctival edema. If you suffer from allergic conjunctivitis, bacterial conjunctivitis and other conjunctival inflammation, or orbital inflammation or intraorbital swelling, or after rubbing the eye locally with the hand, the localization of bulbar conjunctival edema may appear, most of them will be accompanied by conjunctival congestion. 2. Conjunctival cyst. Conjunctival cysts are mostly caused by the proliferation of conjunctival tissue, and there may be fluid inside the cyst. 3. Lymphatic dilatation. Obstruction of perilymphatic circulation in the bulbar conjunctiva may cause dilatation of lymphatic vessels, which may appear as transparent blisters. The specific causes need to be clarified by the patient’s timely medical examination.
