Chemosis occurs when the eye is irritated and the conjunctiva swells. The conjunctiva is the clear membrane covering your outer eye. Because of the swelling, you might not be able to completely close your eyes. Allergens often cause chemosis, but a bacterial or viral infection can also trigger it.
What causes swelling of the conjunctiva?
The conjunctiva is a clear layer of tissue lining the eyelids and covering the white of the eye. Allergic conjunctivitis occurs when the conjunctiva becomes swollen or inflamed due to a reaction to pollen, dust mites, pet dander, mold, or other allergy-causing substances.
What does it mean when you have fluid behind the eye?
Central serous retinopathy is a medical condition where fluid builds up behind the retina in the eye. It can cause sudden or gradual vision loss as the central retina detaches. This central area is called the macula.
What’s edema?

What is sclera and conjunctiva?
The conjunctiva, a thin layer of tissue lining the eye and eyelids, contributes to homeostasis of the tear film, provides a layer of protection from foreign material and wards off infection. The sclera, a dense connective tissue made of collagen and elastin, encapsulates the eye, giving it structure and rigidity.
What is the difference between bulbar and palpebral conjunctiva?
The bulbar conjunctiva covers the anterior part of the sclera (the white of the eye). It does not cover the cornea. The palpebral conjunctiva covers the inner surface of the upper and lower eyelids. The bulbar and palpebral conjunctiva are both continuous, making it impossible to lose a contact lens behind your eye.
What is called conjunctiva?
Conjunctiva: A thin, clear, moist membrane that coats the inner surfaces of the eyelids (palpebral conjunctiva) and the outer surface of the eye (ocular, or bulbar, conjunctiva). Inflammation of the conjunctiva is called conjunctivitis (pinkeye).

What causes redness and inflammation of the bulbar conjunctiva?
Infectious conjunctivitis results in inflammation and redness of the bulbar conjunctiva. Irritation of the palpebral conjunctiva can sometimes cause infection. Conjunctivitis can develop as a result of an irritated palpebral conjunctiva. The palpebral conjunctiva open to the tear ducts.
What is the pathophysiology of conjunctivitis?
Conjunctivitis can develop as a result of an irritated palpebral conjunctiva. The palpebral conjunctiva also contains openings to lacrimal ducts, which provide moisture to the surface of the eye. This prevents chafing of the globe and can flush out small particles that may get in the eye.
