Kearns-Sayre Syndrome is a rare neuromuscular disorder that affects the eye muscles and other muscles. Kearns-Sayre Syndrome is part of the larger group of neuromuscular disorders called mitochondrial encephalomyopathies. Symptoms are:
• Difficulty in opening eyelids
• Restricted eye movements
• Pigmentary retinopathy
• Cardiac conduction abnormalities
• Weakness of facial, trunk and extremities muscles
HOW IS KEARNS-SAYRE SYNDROME DIAGNOSED?
There are two tests that may be performed should a diagnosis of Kearns-Sayre syndrome be suspected. The first involves checking the lactate and protein levels in the person's cerebrospinal fluid. The other test involves examining a biopsy of the person's muscle in order to see if the DNA in their mitochondria is abnormal.
HOW IS KEARNS-SAYRE SYNDROME TREATED?
Treatment is based on the symptoms. Surgery may be needed to correct visual problems. Separate treatments are needed for resolving the various associated disorders.
