Periorbital puffiness, also known as puffy eyes, or swelling around the eyes, is the appearance of swelling in the tissues around the eyes, called the orbits. It is almost exclusively caused by fluid buildup around the eyes, or periorbital edema. Minor puffiness usually detectable below the eyes only is often called eye bags.
An important risk factor is increased intraocular pressure (pressure within the eye) either through increased production or decreased outflow of aqueous humour. [8] Increased resistance to outflow of aqueous humour may occur due to an abnormal trabecular meshwork or due to obliteration of the meshwork resulting from injury or disease of the iris.
Edema may also be found in the cornea of the eye with glaucoma, severe conjunctivitis, keratitis, or after surgery. Affected people may perceive coloured haloes around bright lights. Edema surrounding the eyes is called periorbital edema (puffy eyes) . The periorbital tissues are most noticeably swollen immediately after waking, perhaps as a ...
