Little droop, big challenge: A child's journey with ocular myasthenia gravis

Context: Ocular myasthenia gravis (OMG) is a rare neuromuscular disorder that presents significant diagnostic and therapeutic challenges, particularly in pediatric cases. It can mimic other neurological disorders, leading to misdiagnosis and delayed treatment. Early identification and intervention are crucial in preventing progression and improving patient outcomes. Purpose: This case report aims to highlight the diagnostic approach and management of ocular myasthenia gravis in a pediatric patient. It underscores the importance of comprehensive clinical evaluation and early treatment initiation to enhance the quality of life in affected children. Methods and Material: A 7-year-old female presented with a one-year history of progressive ptosis, more pronounced in the right eye, with diurnal variation. A detailed history was taken, followed by a thorough ophthalmological examination and specialized tests, including the fatigue test, ice pack test, and repetitive nerve stimulation (RNS) test. Serological confirmation was achieved through the detection of elevated acetylcholine receptor antibodies. Results and Conclusion: Clinical and diagnostic findings confirmed seropositive ocular myasthenia gravis. Treatment with oral pyridostigmine and corticosteroids led to significant improvement in ptosis and reduction in diurnal variation. This case emphasizes the necessity of early recognition and tailored management strategies for pediatric ocular myasthenia gravis. Continuous monitoring is essential to detect potential progression to generalized myasthenia gravis and to adjust therapy accordingly.
