Congenital issues are those that are present from birth. A common congenital eyelid problem is drooping of the eyelids, or ptosis. Ptosis most commonly results from poor function of the muscles that lift the eyelid, but may also result from trauma or injury during the birthing process. In some cases, the lid droop can be so significant that it interferes with vision. If this is the case, it is important for the child to undergo ptosis repair in order to prevent amblyopia (“lazy eye”). In cases when the lid droop is not significant enough to impair the quality of vision, and therefore development of the eye, eye lid repair can be postponed until the child is older (around the age of one or older depending upon the circumstances).
