Droopy eyelids can also be caused by trauma, surgery, or by damage to the muscles that raise the eyelids or to the nerves that control these muscles. Tumors, neurological disorders, systemic diseases, and certain drugs have also been known to cause ptosis. Depending on the cause, ptosis may be classified as: Neurogenic ptosis: Refers to the condition in which the nerves attached to the muscle are affected; Myogenic ptosis: Refers to sagging of the lid due to a problem with the muscle that raises the eyelid; Aponeurotic ptosis: Refers to the stretching and weakening of the tendon responsible for raising the eyelid
Amblyopia, also called lazy eye, is a disorder of sight due to the eye and brain not working well together. It results in decreased vision in an eye that otherwise typically appears normal. It is the most common cause of decreased vision in a single eye among children and younger adults. The cause of amblyopia can be any condition that interferes with focusing during early childhood. This can occur from poor alignment of the eyes, an eye being irregularly shaped such that focusing is difficult, one eye being more nearsighted or farsighted than the other, or clouding of the lens of an eye. After the underlying cause is fixed vision is not fully restored as the mechanism also involves the brain.
