Ptosis vs Hooded Upper Eyelids: How to Tell Which You Have

Two different problems that look similar

Patients regularly come in for a blepharoplasty consultation having self-diagnosed hooded eyelids when the underlying issue is actually ptosis. The reverse also happens — patients book a ptosis consultation when the issue is purely excess skin.

The two conditions look similar from the outside. The eyelid appears heavy, the eye looks tired, and the upper lid seems to sit lower than the patient remembers it sitting a few years ago. But the underlying cause is different, the operation that corrects each is different, and the fee structure is different.

This article walks through how the two conditions differ anatomically, a simple at-home assessment that points toward one or the other, and what the consultation conversation typically covers.

What hooded upper eyelids are

Hooded upper eyelids are the result of excess upper-eyelid skin. As the skin loses elasticity over time, it sits lower and lower over the upper-lid crease. In severe cases, the skin can rest against the eyelashes or even drape over the lid margin itself.

The underlying anatomical structures — the levator palpebrae superioris (the muscle that lifts the eyelid), its tendon-like attachment to the lid (the levator aponeurosis), and the position of the lid margin — are unaffected. The lid still opens to its full height when the levator contracts. The excess skin sits above and obscures part of what is happening underneath.

The operation for hooded upper eyelids is a standard upper blepharoplasty: removal of the excess skin (with, where indicated, a small strip of orbicularis muscle or a controlled amount of orbital fat). The incision sits in the natural supratarsal crease so the scar is generally well concealed.

What ptosis is

Ptosis is a drooping of the upper-lid margin itself. The lid margin sits lower than its normal position, partially covering the pupil. The cause is usually weakening of the levator palpebrae superioris — the muscle that opens the eyelid — or of its tendon-like attachment to the lid.

There are several types of ptosis:

• Aponeurotic ptosis — the most common form in adults. The levator aponeurosis stretches or partially detaches over time. The muscle itself still works, but its connection to the lid is weakened.
• Myogenic ptosis — the levator muscle itself is weak, often associated with congenital conditions or muscle disease.
• Neurogenic ptosis — the nerve supply to the levator is affected.
• Mechanical ptosis — a mass or weight on the eyelid is pulling it down.
• Pseudoptosis — the lid appears to droop but the lid margin position is actually normal (often caused by the brow position or by skin laxity sitting over a normal lid margin).

The operation for ptosis is a ptosis repair, which tightens or repositions the levator aponeurosis or muscle to lift the lid margin back to its normal position. This is a different operation to upper blepharoplasty. It involves different surgical planning and different post-operative considerations.

The at-home test

The standard clinical test for distinguishing ptosis from hooded eyelids is the marginal reflex distance (MRD) test. It is performed at examination by the practitioner, but a rough at-home version can give a useful starting point:

1. Stand in front of a mirror in good light, looking straight ahead at your reflection
2. Identify the centre of your pupil (the dark circle in the middle of the iris)
3. Identify where the upper-lid margin (the edge of the upper lid, just above the lashes) sits relative to the pupil

In a normal eye, the upper-lid margin sits 1 to 2 mm below the upper edge of the pupil. The lash line is visible, and a strip of the pupil sits above the lid margin and below the upper edge of the iris.

• If the upper-lid margin sits at or above the upper edge of the pupil — that is the normal range. If there is also excess skin sitting over the lid crease, the issue is likely hooded eyelids (excess skin).
• If the upper-lid margin sits below the upper edge of the pupil, covering part of it — that is consistent with ptosis. The lower the margin sits, the more severe the ptosis.

This is a rough at-home test and is not a diagnosis. Many patients have a combination — some ptosis plus some excess skin — and the consultation will clarify which is the dominant issue.

Why the distinction matters

Performing the wrong operation for the wrong condition produces a poor result.

If a patient with ptosis is given a standard upper blepharoplasty (skin removal only), the lid margin is still drooping after surgery — the eyelid is just less hooded above it. The patient's main complaint is not addressed.

If a patient with purely hooded eyelids is given a ptosis repair, the lid margin is unnecessarily lifted, potentially producing an over-lifted appearance or affecting eyelid closure (lagophthalmos).

For patients with both conditions, the operation is often a combined ptosis repair plus skin removal in the same procedure. The planning happens at consultation after a careful examination.

When to involve a GP

For any of the following, the GP is the right first step before considering surgery:

• The drooping appeared suddenly or has worsened rapidly
• The drooping is only on one side
• There are other neurological symptoms (double vision, headache, weakness elsewhere)
• The patient is experiencing pain in the eye or around it
• The patient has a history of muscle disease or neurological condition

Sudden-onset ptosis can be a sign of an underlying medical problem (for example, a third cranial nerve palsy or myasthenia gravis) and needs medical assessment before any cosmetic discussion.

For ptosis that has developed gradually over years, the GP referral is still the starting point — both for the AHPRA-required cosmetic referral and for any wider medical context.

What the consultation covers

At a Dr Konrat consultation for an upper-eyelid concern, the examination distinguishes between:

• The position of the upper-lid margin relative to the pupil
• The function of the levator muscle (how much lift the muscle is providing)
• The position of the supratarsal crease
• The amount and quality of upper-lid skin
• The position of the brow (a low brow can mimic upper-lid drooping)
• Symmetry between the left and right sides

The findings drive the recommendation. Some patients are best served by a standard upper blepharoplasty; some by a ptosis repair; some by a combined operation; some by no surgery at all if the issue is better addressed by treating the brow position or another underlying cause.

Costs and Medicare

Medicare rebates and private health insurance rebates do not apply to procedures performed at Dr Konrat's practice. Both standard upper blepharoplasty and ptosis repair are classified as cosmetic procedures and no rebate is available.

A personalised fee estimate is provided after consultation. Fees include the practitioner fee, anaesthesia, and facility costs.

Patients with significant ptosis causing functional vision problems sometimes pursue a Medicare-funded pathway through an ophthalmologist. That pathway is separate from this practice and patients who want to explore it should discuss with their GP.

Next step

If you are unsure whether your concern is hooded eyelids, ptosis, or both, the consultation is where that question is answered. The blepharoplasty practice page outlines what the consultation covers, including the anatomy and complications section that gives more detail on the surgical options.
