Chemosis is the swelling (or edema) of the conjunctiva. The term derives from the Greek words cheme and -osis, cheme meaning cockleshell due to the swollen conjunctiva resembling it, and -osis meaning condition. [1] The swelling is due to the oozing of exudate from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of ...
Conjunctival suffusion is an eye finding occurring early in leptospirosis, which is caused by Leptospira interrogans. Conjunctival suffusion is characterized by redness of the conjunctiva that resembles conjunctivitis , but it does not involve inflammatory exudates. [ 1 ]
The bulbar conjunctival microvasculature is known to dilate in response to several stimuli and external conditions, including allergens (e.g. pollen), [32] temperature, [33] time-of-day, [33] contact-lens wear, [13] and acute mild hypoxia. [24] Bulbar conjunctival vasodilation has also been shown to correlate changes in emotional state. [34]
Blepharokeratoconjunctivitis is the combination of conjunctivitis with blepharitis and keratitis. It is clinically defined by changes of the lid margin, meibomian gland dysfunction, redness of the eye, conjunctival chemosis and inflammation of the cornea. [34]
Graves' ophthalmopathy, also known as thyroid eye disease (TED), is an autoimmune inflammatory disorder of the orbit and periorbital tissues, characterized by upper eyelid retraction, lid lag, swelling, redness (), conjunctivitis, and bulging eyes (exophthalmos). [1]
The resulting loose, excess conjunctiva may mechanically irritate the eye and disrupt the tear film and its outflow, leading to dry eye and excess tearing. [2] A correlation may also exist between inflammation in the eye and conjunctivochalasis, though it is unclear whether this correlation is causal.
It could also show corneal oedema which leads to thickening the corneal by up to 30%. Extensive conjunctival injection, which is an enlargement of conjunctival vessels, and conjunctival chemosis, which is the swelling of the tissues that lines the eyelids and surface of the eye. There is also a mild reaction to the anterior chamber of the eye ...
The condition is not congenital and develops over the course of a few months as the lacrimal glands fail to produce tears. Other conditions involved in the progression already stated include the appearance of Bitot's spots, which are clumps of keratin debris that build up inside the conjunctiva and night blindness, which precedes corneal ulceration and total blindness.
