Swollen Eyes: Symptoms & Signs

Medically Reviewed on 9/10/2019

Swelling of the eye, also referred to as periorbital puffiness, refers to the presence of excess fluid (edema) in the connective tissues around the eye, most commonly the eyelids. A swollen eye can result from

  • trauma,
  • infections, or
  • other injuries to the eye area.

Other signs and symptoms can be associated with swelling of the eye, including

  • excess tear production or discharge,
  • eye irritation,
  • eye redness,
  • dry eyes, or
  • obstructed or impaired vision, depending on the cause.

Prolonged crying, trauma, or eye injury is a common cause of swollen eyes. Virtually any cause of inflammation to the eye area may manifest as eyelid swelling, although allergic reactions are likely the most common cause. With allergic reactions, the eyes may also be red and itchy as well as swollen. Rarely, systemic conditions (affecting the entire body) may result in fluid retention, including fluid retention in the tissues around the eyes. With Graves' disease of the thyroid gland, proptosis or exophthalmos can occur. This means protrusion or bulging of the eyeball within the eye socket. Puffiness of the eyelids can also occur with this condition.
