Which of the following is likely to cause sympathetic Ophthalmitis?
Disease Entity and History Sympathetic ophthalmia (SO) is a rare, bilateral, granulomatous uveitis caused by exposure of previously immune-privileged ocular antigens from trauma or surgery with a subsequent bilateral autoimmune response to this tissue.
What is the meaning of sympathetic Ophthalmitis?
Sympathetic ophthalmia is inflammation of the uveal tract (uveitis) that occurs in one eye after injury or surgery to the other eye. Sympathetic ophthalmia is a rare type of uveitis that causes small abnormal clumps of cells (granulomas) to form.

Can one damaged eye affect the other eye?

What is a sympathetic nervous system?
sympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.
What can cause Panuveitis?
It differs from other anatomical sites of inflammation in terms of causes as well as distribution. The common causes of panuveitis in our population are tuberculosis, Vogt-Koyanagi-Harada syndrome, sympathetic ophthalmia, Behcet’s disease and sarcoidosis. A large number of cases still remain idiopathic.
Is Panuveitis serious?
Panuveitis is a major cause of blindness and visual morbidity. The prognosis for people with panuveitis varies depending on the underlying cause and severity. When the condition is unrecognized or inadequately treated, profound and irreversible vision loss can occur.
What causes blood in the eye from a subconjunctival hemorrhage?
Blood in the eye from a subconjunctival hemorrhage usually disappears within a week or two. Although it is not always possible to identify the source of the problem, some potential causes of subconjunctival hemorrhage include: Eye trauma can cause a broken blood vessel.
What is the pathophysiology of sympathetic ophthalmia?
Disease Entity. Sympathetic Ophthalmia is a rare, bilateral, granulomatous uveitis due to trauma (more common) or surgery (less common) to one eye. Louis Braille, the inventor of modern Braille, was injured at the age of 3 in his right eye when he playing with a slender curved knife and is believed to have suffered from sympathetic ophthalmia.
What happens when a blood vessel Pops in the eye?

What is the history of sympathetic ophthalmia?
History. The history plays an important role in the diagnosis of sympathetic ophthalmia. Usually, the patient has a history of trauma or surgery to one eye, either recently or in the past. This diagnosis can sometimes be made after multiple surgeries in an eye, but the vast majority of patients have a history of trauma.
