Kearns-Sayre Syndrome (KSS) is a rare mitochondrial disorder characterized by:
- Progressive external ophthalmoplegia: Weakness or paralysis of the eye muscles.
- Pigmentary retinopathy: Degeneration of the retina.
- Cardiac conduction defects: Abnormal heart rhythms.
Other symptoms may include:
- Muscle weakness
- Hearing loss
- Endocrine disorders
KSS typically presents before age 20. Management involves monitoring and treating symptoms, as there’s no cure. Consult a neurologist or geneticist for guidance.
