The most obvious sign of ptosis is the drooping lid itself. Ptosis can affect one or both eyelids. It may be present at birth (congenital) or occur later in life. In congenital ptosis, the upper eyelid creases may appear asymmetrical.
Children with ptosis may also often tip their head back into a chin-up position to see underneath the drooping eyelid, or they may raise their eyebrows in an attempt to lift up the lids. Both of these positions are signs that the child is trying to use both eyes to see. Over many years, abnormal head positions may cause deformities in the head and neck.
