PTOSIS
DEFINITION OF PTOSIS
Ptosis, also known as droopy eyelid, is a condition where the upper eyelid droops over the eye, partially or completely covering the pupil. It can affect one (unilateral) or both eyes (bilateral) and may be present at birth (congenital) or develop later in life (acquired).
Ptosis can be mild, moderate, or severe, impacting vision and appearance. In severe cases, it can obstruct vision, cause eye strain, and lead to compensatory head tilting or eyebrow lifting.
RISK FACTORS OF PTOSIS
- Aging Process
- Neurological Disorders
- Trauma or Eye Surgery
- Congenital Genetic Conditions
- Diabetes and Hypertension
SYMPTOMS
The most obvious symptom
The eyelid may cover more of the eye than normal
In severe cases, the lid may cover the pupil, obstructing vision
Partial or complete blockage of the upper field of vision
Difficulty seeing when looking upward or straight ahead
May tilt the head back or raise the eyebrows to try to see better
The drooping lid may interfere with normal blinking and tear distribution
This can lead to excess tearing (epiphora) or dryness, irritation, and redness
Tired or achy eyes after reading or doing close-up work
May occur sooner and with less effort than before
Often worsens later in the day
Chronic raising of the eyebrows or tilting the head backward to compensate for blocked vision can cause forehead strain, headaches, and neck discomfort
TREATMENT TYPES
Mild ptosis not affecting vision
Minimal cosmetic concern
Stable cases without progression
- A small device attached to glasses that lifts the drooping eyelid mechanically
Removal of excess upper eyelid skin (dermatochalasis) that contributes to the droopy appearance
Often performed together with ptosis repair
Most common ptosis surgery for acquired ptosis
Tightens or shortens the levator muscle (the muscle that lifts the eyelid)
Raises the eyelid to a more natural position
Minimally invasive technique
Used for mild to moderate ptosis with good eyelid muscle function
Tightens an internal muscle without external skin incisions
FAQS
Ptosis is a condition where the upper eyelid droops lower than normal. It can affect one or both eyes and range from mild cosmetic drooping to severe obstruction of vision.
Causes of ptosis include:
Aging (most common cause; muscle weakness over time)
Congenital ptosis (present at birth)
Neurological conditions (e.g., myasthenia gravis, third nerve palsy)
Eye trauma or previous eye surgery
Tumors or growths affecting eyelid nerves or muscles
Drooping upper eyelid
Obstructed or reduced upper field of vision
Eye strain or fatigue
Headaches or forehead aches from constantly lifting the eyebrows
Asymmetry between the two eyes
Increased tearing or dryness
In children: abnormal head posture (tilting head back to see)
Mild ptosis often poses no health risk.
However, severe ptosis can block vision and affect daily activities.
In rare cases, sudden ptosis can indicate serious neurological problems and requires immediate medical evaluation.
Diagnosis is made through:
Comprehensive eye examination
Measurement of eyelid height and function
Testing for underlying neurological or muscular causes if needed
Photographs are often taken to track progression or document medical necessity for surgery.
