Question
A three-year-old child has developed an unexplained droopy eyelid on the right eye. After receiving an injection of neostigmine at the hospital, there has been no improvement in eyelid elevation. Is it necessary to undergo further examinations?
Answer
Droopy eyelids can be caused by various factors, including neurological, ophthalmological, and endocrine issues. Common causes of ptosis in children include congenital simple ptosis, blepharospasm syndrome, myasthenia gravis, and trauma. In adults, it may be due to myasthenia gravis and chronic progressive external ophthalmoplegia. If there is no improvement after the injection of neostigmine, it is recommended to undergo a comprehensive ophthalmological examination, including a neurological assessment, to determine the specific cause of the drooping and to develop an appropriate treatment plan.
