A very uncommon autoimmune condition called Cogan syndrome affects the inner parts of the ears and eyes. Vertigo, impaired vision, hearing loss, and eye discomfort and pain are all signs of the illness. Pain in the muscles or joints, as well as blood vessel irritation, are possible additional symptoms. It is unclear what causes Cogan syndrome exactly. The disease is hypothesized to result from an autoimmune reaction in which the immune system attacks the tissues in the eyes and ears.



The hallmark symptoms of Cogan’s syndrome (CS), an uncommon chronic inflammatory condition, are interstitial keratitis and sensorineural hearing loss. Deafness could occur if inner ear illness recurs frequently. Systemic vasculitis could also be present in some cases. Due to its rarity, the lack of a confirmed diagnostic test, and the nonspecific clinical indications at the beginning, the diagnosis of CS is frequently missed or delayed.

The causes of CS are unknown, although, during the past ten years, the disease’s pathophysiology has become somewhat clearer, raising the possibility that inner ear autoimmunity is to blame. According to the pathogenic hypothesis, immunological mimicry, self-perpetuating irritation caused by the production of cytokines, and the discovery of hidden epitopes are the key mechanisms by which a viral infection causes the disease. In addition to its clinical similarities to other autoimmune diseases, various autoantigens, specifically CD148 and connexin 26, have reportedly been discovered. Early treatment should be begun.



It is unclear what causes Cogan syndrome exactly. The disease is hypothesized to result from an autoimmune reaction in which the immune system attacks the tissues in the eyes and ears. It is unknown if Cogan syndrome runs in families. The primary causes of Cogen’s syndrome are:

  • Degeneration of the epithelial basement membrane.
  • Bowman’s membrane-related dystrophy.
  • Dystrophic stroma.

Many individuals with Cogan’s syndrome experience irreversible hearing or vision loss. Just over ten percent of patients with the condition die as a result. But with the right treatment, the majority of patients are able to control their symptoms and keep illness consequences to a minimum.



The following are some of Cogan’s syndrome’s most typical signs:

  • Bad balance.
  • Nauseous and vomit.
  • Fatigue, fever, and weight loss.
  • The vision is blurry or has red, stinging, light-sensitive eyes.
  • Hearing loss could go really bad and stay that way.
  • Vertigo (also known as dizziness; the sense that the room is spinning).

Rarely, Cogan’s syndrome might result in a rash, chest discomfort, arm pain, shortness of breath, swollen lymph nodes, and several other symptoms.



After identifying the characteristic constellation of issues linked to this condition in the inner ear and eye, a doctor diagnoses Cogan’s syndrome. The diagnosis might not be established until both the eye and the inner ear are impacted. Either one may experience symptoms first, or both the ear and eye issues may appear simultaneously.

Infections, such as syphilis, TB, viral infections, and chlamydia, as well as other rheumatic diseases, such as rheumatoid arthritis, sarcoidosis, and granulomatosis with polyangiitis, will be ruled out by your doctor. The signs of Cogan syndrome are observed, and other potential sources of the symptoms are ruled out, to determine whether the illness is present. Immunosuppressive drugs and corticosteroids are frequently used as treatment alternatives.
