Ptosis refers to the function of superior eyelid muscle and smooth muscle is incomplete or lost, so that the upper eyelid shows part or all drooping. It can affect one or both eyes. In less serious ptosis, the eyelidcovers a part of the pupil while inserious case the pupil may be completely covered.Congenital ptosis maylead to amblyopia. In order to overcome visual impairment, some patients with bilateral eyelids drooping need toraise the head in order to see, thus to form an abnormal posture.
The vast majority of patients are due to the hypoplasia or defect of the upper papillary muscles, or due to the innervation of the superior papillary muscle. The congenital developmental deformity, mostly bilateral, sometimes unilateral, can be autosomal dominant or recessive inheritance.
Acquired ptosis can be the result of an underlying medical condition, ranging from a stroke to muscular dystrophy. The condition can be related to muscle weakness or paralysis, or damage to the nerves which innervate the eyelid. Ptosis can also result from trauma, eye surgery injury or aging.
Treatments of Ptosis
The purposes of ptosis treatments are to prevent the loss of vision and improve the appearance and need to be planned according to the cause of the condition. Congenitalptosis, if it affectsvision development, should be corrected in an early stage. If it is mildand does not interferes the visual development, surgery can be elective aiming forappearanceimprovement. Unilateral ptosis with pupil being covered need to be operated early, preferably before the age of 6, in order to prevent the formation of the amblyopia. Medication can be applied in some cases such as myogenic ptosis or paralytic ptosis. If proved to be ineffective, surgery is still necessary.
