What causes ptosis?
It is possible for ptosis to be present at birth (congenital ptosis), and it is also possible for persons with normal eyelids to acquire ptosis through a variety of causes. These include:
As we age, the muscles that support our eyelids weaken, causing our eyelids to droop. Most ptosis cases are age-related.
Trauma or injury to the eye can weaken or damage the levator aponeurosis, the muscle that lifts the eye. Consequently, this damage can result in upper eyelid drooping.
On the off chance that only one of your eyelids experiences drooping, it might be an aftereffect of a nerve injury or a stye. Routine LASIK or cataract surgery can occasionally result in ptosis due to the levator muscle or tendons in the area getting stretched from the procedure.
- Long term contact lens use
Prolonged stretching of the eyelid can cause the eyelid to stretch over time. This stretching causes the eyelid to fall lower, and in some cases, obstruct the person’s ability to see properly.
Ptosis may be a sign of an underlying medical condition, especially if both eyelids droop. These conditions may include a stroke, tumours of the brain, or malignant cancers of the nerves or muscles.
