Ptosis The eyelids are organs that help protect the eyeball from sunlight, dust, or foreign objects.
The eyelids can open with a command from ทางเข้า ufabet the brain through the third pair of nerves. Ptosis is a condition in which the upper eyelid droops lower than normal, covering the pupil by more than 2 millimeters. If it droops until it covers the pupil, vision can be affected.
Causes of ptosis are divided into two groups:
1. Caused by abnormalities of the nervous system, such as:
– Weak eye muscles (Myasthenia gravis, MG) is an autoimmune disease that can occur with any muscle in the body. The main symptom is drooping eyelids that change during the day. Symptoms tend to be worse in the evening and get better when resting. Some people may also have double vision, difficulty breathing, or choking on food.
– Weakness of the third pair of cranial nerves can occur due to several causes, such as lack of blood supply to the third pair of cranial nerves, a tumor pressing on the nerves, an aneurysm pressing on the nerves, or an accident causing the nerves to rupture.
2. Caused by muscle abnormalities
Congenital ptosis may be caused by abnormal eyelid muscles that are present since birth. If the eyelid droops down until it covers the pupil, it may cause amblyopia. Therefore, if you suspect that your child has ptosis, you should see an ophthalmologist immediately to assess the severity and whether surgery is required.
Occurs later, such as
- Had an accident in the eyelid area
- Blepharitis
- Rubbing your eyes frequently or wearing contact lenses with an improper curvature can cause your eye muscles to stretch or become injured.
- As we age, the attachment of the eye muscles deteriorates and they become detached.
Treatment of ptosis
Treatment will be based on the cause of ptosis. For example, if it is caused by abnormal eye muscles, surgery can be performed to correct the eye muscles. If it is caused by weak eye muscles (myasthenia gravis), symptoms can be relieved with medication.
