What is Ptosis?
Ptosis (pronounced ‘toe-sis’) refers to a drooping of the upper eyelid. As the upper eyelid droops, the upper part of vision may be covered. The obstructed vision may be made worse if there is accompanying excess skin on the upper eyelid.
This condition can affect children and adults, and may occur in one or both eyelids. Whether ptosis is present from birth or develops gradually over time, it can lead to a tired appearance and affect your vision.
Causes of Ptosis
The levator and Muller’s muscles are the two main muscles that raise the upper eyelids.
Droopy eyelids may present at birth (congenital) or later in life (acquired).
Congenital ptosis may be caused by mal-development of the levator muscle or birth trauma.
Acquired ptosis may be due to the following:
-
Ageing
-
Prolonged contact lens wear
-
Injury to the eyelid
-
Eye allergies and/or constant eye-rubbing
-
Nerve damage
-
Muscular disorders like myasthenia gravis or muscle dystrophies
-
Eyelid infection
-
Growth within the eyelid
Symptoms of Ptosis
-
Eyelid become more difficult to keep open
-
Tired appearance
-
Headache or brow aches in effort to lift the eyelids
-
Vision is better when lids are lifted up, or the need to tilt head backwards to see clearly
Diagnosis & Evaluation
A thorough clinical assessment by a senior ophthalmologist is essential. We examine the eye to determine the underlying cause of the ptosis and evaluate how significantly it impacts your field of vision and overall quality of life.
Your evaluation results from various precise clinical steps:
- Detailed measurements of the eyelid.
- Testing levator muscle strength and overall eye movements.
- Photography and imaging to document findings for baseline comparison.
- A visual field test to assess the impact of the ptosis on your visual function
Importantly, our specialists work to rule out serious nerve conditions. This comprehensive evaluation ensures that any treatment recommended is both safe and medically appropriate for your specific condition.
Treatment Options for Ptosis
Non-Surgical Options
Some causes of droopy eyelid such as Myasthenia Gravis or eye allergies may improve with treatment of the underlying disease using appropriate medication.
Surgical Correction
Some forms of ptosis, especially those due to ageing, may require surgery to elevate the eyelid and allow better vision. Surgery can be performed through the external approach (via the skin) or internal approach (without a scar). Risks and benefits of the surgery will be discussed during the consultation.
