What causes ligneous conjunctivitis?
Ligneous conjunctivitis may be inherited in an autosomal recessive pattern due to mutations in the plasminogen (PLG) gene and a variety of other genes, associated with type I plasminogen deficiency (hypoplasminogenemia), leading to impaired wound healing.
What is serous conjunctivitis?
Disease Ontology : 12 A viral acute conjunctivitis that is characterized by conjunctival inflammation and serous discharge. MalaCards based summary : Serous Conjunctivitis Except Viral, is also known as serous conjunctivitis, except viral. Affiliated tissues include eye.
What is congenital plasminogen deficiency?
Congenital plasminogen deficiency is a disorder that results in inflamed growths on the mucous membranes, which are the moist tissues that line body openings such as the eyelids and the inside of the mouth. Development of the growths are usually triggered by infections or injury, but they may also occur spontaneously …
What is angular conjunctivitis?

What is mild follicular conjunctivitis?
Follicular conjunctivitis is the mildest form of a viral conjunctival infection. It has an acute onset, initially unilateral with the second eye becoming involved in a week. It presents with a watery discharge, conjunctival redness, follicular reaction and a preauricular lymphadenopathy on the affected side.
How can you tell if conjunctivitis is viral or bacterial?
Eye doctors have a few tricks. Viral pink eye usually starts in one eye following a cold or respiratory infection and causes watery discharge. Bacterial pink eye can affect one or both eyes and usually starts with a respiratory or ear infection. The discharge tends to be thick and makes the eyes stick together.
How do you know if an eye infection is viral or bacterial?
Bacterial pink eye often appears redder than viral pink eye. While viral pink eye may cause your eyes to water, bacterial pink eye is often accompanied by green or yellow discharge. Viral pink eye also often begins with a cold, whereas bacterial pink eye is associated with respiratory infections.
How is plasminogen deficiency tested?
Diagnosis is confirmed by specific laboratory tests that measure the activity and immunoreactive level (also called the antigen level) of plasminogen; the activity level is decreased while the immunoreactive level is normal or near normal. These tests are available in most clinical coagulation laboratories.
What does plasmin do to fibrin?
A fibrin network forms that traps cells and debris, preventing blood loss. Plasmin cleaves fibrin. Plasmin is a serine protease that hydrolyzes the peptide bonds located on the carboxyl side of lysines and arginines in fibrin. Cleaving bonds in fibrin leads to the dissolution of the clot.
What causes angular blepharitis?
Angular blepharitis is inflammation of the eyelid skin at the lateral canthus, most commonly caused by Staphylococcus and Moraxella species. The Demodex mite is an external parasite that often infests the human eyelid margin and has been implicated in both anterior and posterior blepharitis.
What vitamins help blepharitis?
No alternative medicine treatments have been proved to ease the symptoms of blepharitis. However, a diet rich in omega-3 fatty acids or supplements containing omega-3 fatty acids might help blepharitis associated with rosacea. Omega-3 fatty acids are found in foods such as salmon, tuna, trout, flaxseed and walnuts.
