Chemosis: Infection in the eye


Overview:
Chemosis is the infection of the eye which occurs as a swollen at the conjunctiva of the eye.
The condition mainly caused by the exudation of the small capillaries of the eye, presenting an abnormal permeability.
The inflammation of the conjunctiva leads to an overall gelatinous appearance. The degree of the inflammation is varying from one person to another

Symptoms:
These are the most common symptoms of chemosis:
-Inflammation of the conjunctiva
-The eyes appear to be red and watery
-Excessive tearing  .
-Itchiness caused by the secondary bacterial infection  .
-Gelatinous appearance of the conjunctiva
-The vision is affected and eyeball appears to have moved from its original position this is because of the inflammation of the conjunctiva
-The eyelids can become inflamed so patient cannot close his/her eyes   .

Causes:
These are the most common causes that lead to the appearance of chemosis:
- Allergy – which causes chemosis,  itchiness and watery eyes  .
- Viral infection – there are different viruses that can lead to the inflammation of the conjunctiva (often transmitted through objects of personal hygiene, such as towels)
- Obstruction of the superior vena cava (the diagnosis can be confirmed if the patient presents facial edema as well)
- Thyroid disorders – is present in people who have been diagnosed with hyperthyroidism   .
- Thrombosis of the cavernous sinus – this is a serious condition often associated with Paranasal sinus infection, in which a blood clot forms at the level of the cavernous sinus, which is actually a cavity at the base of the brain (drains blood from the brain, sending it to the heart).
 - Carotid-cavernous fistula
- Systemic lupus erythematosus – the immune system attacks the healthy tissues of the body  as connective tissues  .
- Panophthalmitis – inflammation of the eye coats, including at the intraocular level
- Orbital cellulitis –  caused by  an acute infection that makes a severe inflammation of the eye tissues
- Dacryocystitis – infection of the lacrimal sac, which appears due to the obstruction of the nasolacrimal duct .

Diagnosis:
The diagnosis of chemosis is made through the following methods:
- Patient anamnesis.  
- Physical examination – the doctor will take a closer look of eye by  using specific ophthalmologic instruments  .
- Biopsy – this is recommended only when there is a suspicion of a tumor .

Treatment:
In order for the symptoms of chemosis to improve, one must first treat the underlying condition     .
These are the most common treatments recommended for chemosis:
Anti-histamines: in case of severe allergic to reduce the inflammation .
Antibiotics: for secondary bacterial infections and should be taken for as long as they are prescribed, otherwise the bacteria will develop resistance to the treatment
Anti-inflammatory medication:
-Topical or oral administration to reduce the inflammation and feel relief from the other symptoms as pain and itchiness
- Adrenaline
-Administered as emergency treatment, in case of severe allergic reactions
-People who are allergic carry these allergy shot every time
