Ever noticed how some people constantly look sleepy? Most of the time, their eyelids look very heavy and droopy. For most cartoon lovers, a typical visual example is “Droopy the master detective”. Well, people with such symptoms most likely are experiencing a case of ptosis.
Ptosis, also known as a drooping eyelid or blepharoptosis is a condition whereby the border of the upper eyelid falls to a lower position than normal.
It can affect one or both eyes and may be present at birth, or may develop gradually over the years. Ptosis is usually temporary, but in rare cases, might be permanent.
In addition, it changes the appearance of the individual without changing the vision or health and barely noticeable in most cases and does not have a major effect in daily life.

Major causes include;
· Damage of the nerves that control the muscles in the eyelid.
· Weakness of the muscles that raise the eyelid.
· Looseness of the skin of the upper eyelid
· Birth
· Normal ageing process.
· Result of an injury.
· Diseases such as tumour around the eye, diabetes, stroke, Horner syndrome etc.
Also, treatment depends on the severity of the condition. In many cases, ptosis rarely causes discomfort or other issues, so treatment is often not required.
However, surgery may be used to treat this disorder in specific cases.
Generally, ptosis is not a condition which should cause alarm because most cases are temporary and resolve on their own. Some cases however, may be so severe that they cause blindness. See a doctor if you are concerned about the condition.
