However, ptosis of the upper eyelid can be a symptom of several health conditions, including diabetes, diseases of the nervous system such as myasthenia gravis, or damage to the third cranial nerve that controls the eyelids. Myasthenia gravis is a serious autoimmune neuromuscular disease that results in nerve weakness.
If severe or left untreated, the droopy eyelid can lead to other conditions such as amblyopia (lazy eye) or astigmatism. There are two types of ptosis: acquired and congenital. Congenital ptosis is present at birth and is usually due to the lack of development of eyelid muscles called levators.
