An 11-year-old boy presented with drooping of both the eyelids for past three years. It was insidious in onset, bilaterally symmetric, and slowly progressive in nature. There was no history of double vision, facial weakness, difficulty in swallowing, change in voice, easy fatigability, limb weakness, and palpitation. There was no history suggestive of diurnal variation in symptoms. He was born to non consanguineous parents and the family history was noncontributory. He was a class 5 student with good scholastic performance. On examination he had bilateral ptosis [Figure 1]a and external ophthalmoparesis. Rest of neurological examination was unremarkable. The possibilities considered were ocular myasthenia and progressive external ophthalmoplegia.{Figure 1}

Fundoscopy revealed pigmentary changes [Figure 1]b. Repetitive nerve stimulation test was normal. Anti acetyl-choline-esterase receptor antibodies were undetectable. Magnetic resonance imaging of brain showed signal changes in dorsal brain stem [Figure 2]. Cerebro-spinal fluid (CSF) examination; which revealed elevated protein (147 mg/dL) and lactate levels (2.9 mmol/L). His 12 lead electrocardiogram and Holter was normal. Endocrine evaluation revealed elevated random blood sugar (367 mg/dL) and Hb1Ac (7.8%). A diagnosis of Kearns Sayre Syndrome was made based on the clinico-radiological ground. Genetic analysis could not be done due to non-affordability. He was started on folinic acid, thiamine, CO-enzyme-Q, and daily subcutaneous insulin.{Figure 2}

KSS is a rare mitochondrial disorder with multisystem involvement.[1] The classical triad of KSS includes progressive external ophthalmoplegia, retinal pigmentary changes, and onset before 20 years of age.[2] The additional features includes elevated CSF protein levels (>100 mg/dL), cardiac conduction block, and cerebellar ataxia. For the clinical diagnosis one should have the classical triad plus one or more of the additional characteristics.[3] MRI in KSS classically involves caudate nuclei, globus pallidi, thalami, periventricular white matter, dorsal medulla, and cerebellar white matter.[4] Isolated brain-stem abnormalities may be seen[5] in early stage as seen in our case. There is no definitive treatment for this condition, high dose folinic acid have been tried with limited success. In conclusion, myasthenia should be ruled out in any child who presented with ptosis and external ophthalmoplegia because it is a treatable condition and patients with KSS requires multisystem screening, and early diagnosis can prevent sudden deaths secondary to cardiac conduction abnormalities.
