Ptosis is a medical condition characterized by drooping or sagging of the upper eyelid. This can occur in one or both eyes and may be mild or severe. Ptosis can be caused by a variety of factors, including age-related weakening of the muscles that lift the eyelid, nerve damage, injury, or certain medical conditions such as myasthenia gravis. Ptosis can affect a person's vision and appearance, and in severe cases may require surgical correction.

Ptosis is a medical condition characterized by drooping or fallen eyelids. It can affect one or both eyes and may be present from birth (congenital) or develop later in life (acquired).
Types of Ptosis:
- Congenital ptosis: Present at birth, caused by developmental abnormalities of the levator palpebrae superioris muscle (the muscle that lifts the eyelid).
- Acquired ptosis: Develops later in life due to various factors such as:
- Aging
- Nerve damage
- Trauma
- Myasthenia gravis (autoimmune neuromuscular disorder)
- Eyelid tumors
- Hormonal imbalances
Symptoms:
- Drooping or fallen upper eyelid(s)
- Constricted field of vision, especially in the upward direction
- Forehead wrinkles or eyebrow elevation to compensate for limited upward gaze
- Double vision (in some cases)
Causes:
Congenital ptosis:
- Aplasia or hypoplasia (underdevelopment) of the levator palpebrae superioris muscle
- Nerve abnormalities
Acquired ptosis:
- Aging (senile ptosis)
- Oculomotor nerve palsy (cranial nerve damage)
- Trauma
- Heavy eyelid syndrome
- Myasthenia gravis
- Eyelid tumors
- Hormonal changes (e.g., thyroid disease)
Treatment:
Treatment options depend on the underlying cause and severity of ptosis.
- Congenital ptosis:
- Surgical repair (levator advancement or shortening) to strengthen the eyelid muscle
- Acquired ptosis:
- Surgical repair if the condition is severe or interferes with vision
- Treatment of the underlying medical condition (e.g., nerve repair, tumor removal)
- Ptosis crutches (eyelid tapers or glasses) to prop up the eyelid
- Botulinum toxin injections (to weaken the eyebrow muscle and improve eyelid elevation)
Complications:
- Reduced vision
- Dry eye syndrome
- Astigmatism
- Corneal abrasions (due to exposure)
