Eyelid swelling can be caused by local conditions, such as insect bites or allergy (Fig 10-17), or systemic conditions, such as cardiovascular disease, renal disease, thyroid eye disease, and collagen vascular disease. Cerebrospinal fluid leakage into the orbit and eyelids after trauma may mimic eyelid edema. Lymphedema may occur if the lymphatic drainage system from the eyelid is disrupted, such as after extensive lymph node dissection of the neck (Fig 10-18).
