Cogan syndrome
Cogan syndrome is a rare disorder characterized by recurrent inflammation of the front part of the eye (the cornea) and often involves the ears, leading to hearing loss, dizziness, and vision problems.
Pronunciation
Cogan syndrome is pronounced as KOH-gan syndrome.
Etymology
The syndrome is named after Dr. David Glendenning Cogan, an American ophthalmologist who first described the condition in 1945.
Symptoms
The primary symptoms of Cogan syndrome include keratitis (inflammation of the cornea), vertigo (a sensation of feeling off balance), tinnitus (ringing in the ears), and sensorineural hearing loss (a type of hearing loss in which the root cause lies in the inner ear or sensory organ).
Causes
The exact cause of Cogan syndrome is unknown. However, it is thought to be an autoimmune disease, where the body's immune system mistakenly attacks its own tissues.
Diagnosis
Diagnosis of Cogan syndrome is primarily based on the presence of the characteristic symptoms. Additional tests such as audiometry (hearing tests), vestibular tests (balance tests), and ophthalmologic examination (eye tests) may be conducted to confirm the diagnosis.
Treatment
Treatment for Cogan syndrome primarily involves managing the symptoms. This may include the use of corticosteroids to reduce inflammation and immunosuppressive drugs to suppress the body's immune response.
Prognosis
The prognosis for individuals with Cogan syndrome varies. Some individuals may experience mild symptoms and have a good prognosis, while others may experience severe symptoms and have a poorer prognosis.
