Eyelid Swelling: Causes and When to Worry

Is eyelid edema the same as eyelid swelling?

Yes. Eyelid edema is the medical term for eyelid swelling. Edema means excess fluid in the tissues. Because eyelid skin is the thinnest in the body and the tissue underneath is loose, small amounts of fluid collect there easily, especially after lying flat overnight. Periorbital edema refers to swelling around the whole eye, including the eyelids and the skin around the socket. Doctors also distinguish edema from inflammation, such as an infected eyelid, and from a lump such as a chalazion, but in everyday language all of these are called eyelid swelling.

Common causes of eyelid swelling

Allergies and irritation

• Allergic conjunctivitis from pollen, dust mites or pet dander: both eyes, itchy, watery and puffy.
• Contact dermatitis from eye makeup, nail polish (transferred by touching), hair dye, eye drops or skin care: itchy, dry, red, scaly eyelid skin.
• Insect bites on the lid: often dramatic swelling on one side, itchy rather than painful.

Lumps on the eyelid

• Stye (hordeolum): a painful red bump at the lid margin from an infected eyelash follicle or oil gland. Usually drains within a week. See stye.
• Chalazion: a firm, usually painless lump further back in the lid from a blocked oil gland. It can cause general lid swelling at first.

Inflammation and infection

• Blepharitis: chronic inflammation of the lid margins with crusting, gritty eyes and mild swelling.
• Conjunctivitis: viral or bacterial pink eye can make the lids puffy, with redness and discharge.
• Preseptal (periorbital) cellulitis: infection of the eyelid skin and tissue in front of the orbit. The lid is red, swollen and tender, but vision and eye movement are normal.
• Orbital cellulitis: infection behind the orbital septum, often spreading from the sinuses. It causes pain on eye movement, a bulging eye and reduced vision. It is an emergency treated with IV antibiotics.
• Shingles of the ophthalmic nerve.

Fluid retention

Fluid that collects overnight makes both eyelids puffy in the morning. Triggers include salty food, alcohol, crying, poor sleep, the menstrual cycle and pregnancy. Persistent morning puffiness can also be a sign of kidney disease such as nephrotic syndrome, heart failure or an underactive thyroid.

Other causes

• Angioedema: sudden, non-itchy deep swelling of the lids, lips or face from allergy, ACE inhibitor medicines or hereditary angioedema.
• Thyroid eye disease: puffy lids, bulging eyes, a staring look and grittiness, usually in Graves' disease.
• Injury: a black eye or bruising after a blow.
• Aging: fat behind the lids bulges forward to form permanent "eye bags".
• Rarely: dermatomyositis (purple-tinged lid swelling), eyelid tumors and infections such as Chagas disease.

Clues to the cause

How a doctor finds the cause

The doctor will ask about itching, pain, discharge, recent colds or sinus infection, new cosmetics or medicines, insect bites and general health. They will check your vision, eye movements, pupils and whether the eye bulges, and turn the lid to look for a chalazion. Most cases need no tests. A CT scan is done if orbital cellulitis is suspected. Urine and blood tests check kidney and thyroid function when both eyes are puffy every morning.

Treatment and home care

• Cold compresses for 10 minutes several times a day reduce allergic and fluid swelling.
• Warm compresses for 10 to 15 minutes, 3 to 4 times a day, help a stye or chalazion drain. Never squeeze it.
• Antihistamine eye drops or tablets for allergies, following the label dose.
• Stop suspected cosmetics or skin products and use only fragrance-free cleansers.
• Lid hygiene for blepharitis: warm compresses followed by gentle cleaning of the lash line.
• Antibiotics by mouth for preseptal cellulitis; IV antibiotics in hospital for orbital cellulitis.
• Raise your head on an extra pillow and limit salt and alcohol for morning puffiness.
• Remove contact lenses until the swelling and any infection have cleared.

A chalazion that persists for more than a month can be drained or injected by an eye doctor.

Frequently asked questions

Is eyelid edema the same as eyelid swelling?

Yes. Eyelid edema is the medical term for a swollen eyelid caused by extra fluid in the tissue. Doctors may use "eyelid swelling" more broadly to include inflammation and lumps such as a stye or chalazion, but in practice the two terms describe the same visible puffiness.

Why is only one of my eyelids swollen?

Swelling in one eyelid usually has a local cause: a stye, chalazion, insect bite, injury, contact dermatitis or an infection such as preseptal cellulitis. If one lid is red, hot and painful, especially with fever or vision problems, see a doctor the same day.

How do I get rid of a swollen eyelid fast?

For allergic or morning puffiness, apply a cold compress for 10 minutes and take an antihistamine if allergy is likely. For a stye, use warm compresses several times a day. Avoid rubbing and makeup. Swelling that is painful, spreading or affects vision needs medical care.

When should I worry about a swollen eyelid?

Worry if swelling comes with eye pain, pain when moving the eye, double or blurred vision, a bulging eye, fever, spreading redness or difficulty breathing. These need urgent or emergency care. Also see a doctor if puffy eyelids happen every morning without explanation.

Can kidney problems cause puffy eyelids?

Yes. Kidney diseases that leak protein into the urine, such as nephrotic syndrome, often cause puffy eyelids that are worst in the morning, along with foamy urine and ankle swelling. A simple urine test can check for protein.
