A lump in the lower eyelid of the eye may be caused by the following conditions: first, dermatoglyphic cysts, which are relatively common benign tumors of the eyelid and appear as painless, mobile lumps under the eyelid skin. The principle of treatment in the early stages is to apply local heat to promote absorption of the lumps, and if conservative treatment is not effective, surgical removal can be considered; thirdly, in the abscess stage, the disease is caused by bacterial infection, and the lumps are not obvious in the early stages, but only after the abscess is formed in the later stages will they show up as lumps under the eyelid skin, which requires surgical treatment.
