Corneal puckering refers to wrinkling and edema of the bulbar conjunctiva of the eye. The bulbar conjunctiva is thin, with vascular tissue attached to the anterior scleral surface, the bulbar conjunctiva and the tissue behind it, with looser connections. Once inflammation or other causes exist, the bulbar conjunctiva will become congested or edematous. There are several reasons for the occurrence of bulbar conjunctival fold edema: 1. Short-term bulbar conjunctival edema: mostly belongs to local inflammation, such as allergic, acute conjunctivitis, but also can be associated with lymphatic reflux obstruction, with eye redness, eye discharge and other inflammatory conditions. Anti-inflammatory eye drops, such as levofloxacin drops, can be used to relieve symptoms. Lymphatic reflux obstruction leads to bulbar conjunctival edema, local hot compresses can be applied to relieve symptoms. 2. Bulbar conjunctival relaxation: No special treatment is needed when it is mild and does not affect vision and eye function. If the relaxation of the bulbar conjunctiva leads to foreign body sensation in the eye, surgical treatment can be considered; 3. Systemic diseases: Cardiogenic or pulmonary diseases may appear as bulbar conjunctival edema. The occurrence of bulbar conjunctival edema needs to be analyzed on a case-by-case basis to select a suitable treatment plan.
