Dropped eyelid (ptosis) is when the upper eyelid level is lower than normal. This drooping can block the pupil and prevent vision. In severe cases, head positioning or manual eyelid lifting is used to ensure vision. Drooping eyelids can be congenital due to the muscle that lifts the eyelid not developing sufficiently or can be due to aging. In congenital cases, it is necessary to shorten the weak muscle or use a sling in more severe cases. Drooping eyelids can also develop after eye surgeries such as cataracts and detachment.
