Scleritis is a serious inflammatory disease that affects the white outer coating of the eye, known as the sclera. The disease is often contracted through association with other diseases of the body, such as granulomatosis with polyangiitis or rheumatoid arthritis. There are three types of scleritis: diffuse scleritis (the most common), nodular ...
Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.
The episclera is a thin layer of tissue that lies between the conjunctiva and the connective tissue layer that forms the white of the eye . Episcleritis is a common condition, and is characterized by the abrupt onset of painless eye redness. There are two types of episcleritis, nodular and simple.
If your whole eye has gone red, learn about the causes of bloodshot eyes and how to fix them. Weirdly enough, a red spot on eye might have a cause totally unrelated to your eyes: sneezing or coughing.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
The etiology of multiple evanescent white dot syndrome is currently unknown but two potential origins have been postulated. Gass, et. al. suggests a virus invades retinal photoreceptors through cell-to-cell transmission via either the ora serrata or optic disc margin. [3]
Redness of the sclera is typically caused by eye irritation causing blood vessels to expand, such as in conjunctivitis ("pink eye"). Episcleritis is a generally benign condition of the episclera causing eye redness. Scleritis is a serious inflammatory disease of the sclera causing redness of the sclera often progressing to purple.
