A swollen eyelid can be caused by a number of different reasons but the most common causes include allergy apart from eye infections, an injury to the eye and sometimes trauma can also result in a swollen eye. In some cases like ocular herpes, orbital cellulitis and Graves’ disease, a swollen eye is just a symptom and indicates the presence of a problem that can result in sight loss in some cases as well. The swelling can occur below or above the eyelid on both eyes.
The swelling is caused by the presence of excess edema in the tissues that are near the eye or can be caused by inflammation as well. It is imperative that you visit your ophthalmologist for a complete checkup in case your swelling does not go away in a normal period of time or is getting worse with the passage of time.
Possible Causes of Swollen Eyelid
There are a number of allergies which can cause swelling in the tissue around the eyelid. The allergic reaction which causes this swelling is mostly mild but sometimes the swelling is caused by a critical allergic reaction.
The swelling can be caused by a reaction to dust or cosmetics or even pollen.
An allergic reaction to the bite of an insect can also result in a swollen eye.
Such swelling is also indicative of reaction to animal dander.
Penicillin or codeine can also trigger an allergic reaction which causes such swelling on the eyelid.
A swollen eye can also be caused by an anaphylactic allergic reaction.
Apart from allergic reaction, swelling in the eyelid can also be caused by an infection. Some of the most common infectious causes of this swelling are:
Cellulitis is a skin infection which can result in swelling above or below the eyelid.
A viral herpes infection can also result in a swollen eyelid.
An infection of the sinus can also result in eyelids which are swollen.
An eyelash follicle which has been infected can also cause tissue around the eyelid to become swollen.
Mumps and Dacryocystitis are also infections which can cause eyelid swelling.
Conjunctivitis which is also known as pink eye causes the eye surface to become inflamed. Apart from causing itching in the eye, conjunctivitis also results in swollen eyelids.
Meibomian gland can become inflamed when infected by bacteria. Such an infection is called stye which also causes the eyelids to become swollen.
Chalazion which is similar to stye in some ways also results when the meibomian gland becomes blocked. However, it results in a sebaceous cyst which is hard. The infection also results in eyelid becoming inflamed.
Improper use of contact lenses or using them inappropriately can also cause an infection that result in swollen eyelids.
Inflammation of the tissue around the eyelids can also be caused by a trauma or an injury. Some of the most common traumatic causes of such swelling include:
A foreign object entering the eye can causes swelling of the eyelids.
Surgery of eye or face can sometimes cause eyelids to swell.
An injury to the eye is also a reason because of which eyelids can swell.
Eyelids can also swell if there are burns on the face.
