Ptosis is a medical condition that describes the dropping of the upper eyelid. Ptosis might affect one or both of our eyes. Ptosis results in patients having a constant “sleepy” or “drowsy” look on their faces, giving the perception that they are always tired. Patients suffering ptosis would also result in having their field of vision partially blocked or obstructed due to the dropping eyelid.
Ptosis can be both congenital (present at birth) or acquired. The reasons for acquired ptosis is due to the weakening of muscles in the eyelids which could be brought about due to aging or the frequent use of contact lenses. It could also be due to the stretching of the lining which supports the upper eyelid. This lining is known as the levator muscle. Only surgery can restore the proper functioning of the eyelid.
The aim of ptosis surgery would be increase and permit a full view of vision by elevating the upper eyelid, while aiming for a reasonable amount of symmetry for both eyes. This could be achieved by tightening the levator muscle and also by removing excess fat and tissue in the affected eyelids. The surgery is conducted under local anaesthesia and it usually takes around 1 – 2 hours. Operation of on both eyelids could be done at the same time.
After the surgery, the eyelid that was operated on would be swollen and cold compression should be applied to reduce swelling. Patients would also suffer from blurry vision. Eyelids would also be stiffer than usual and this could result in eyes being dry. Patients are encouraged to apply eye drops to reduce dryness of the eyes.
