3.You Were Born With Them
Some babies are born with one or two droopy eyelids. It happens when the muscle that holds up the eyelid doesn’t form the right way. Kids with ptosis might have less vision in the top part of their eye. They may tilt their head back to see better. Sometimes they get amblyopia, or “lazy eye.” Your doctor might suggest surgery to raise their eyelid.
4.Horner Syndrome
This is when damage to certain nerve pathways makes your eyelid sag. The affected eye might have a smaller pupil, and part of your face might not sweat. Some people are born with Horner syndrome. But noncancerous (benign) or cancerous tumors, like ones in your brain, head, or lungs, can also damage these nerves. Your doctor will check for diseases that limit blood flow to your head and neck.
