Ptosis refers to the drooping of the upper eyelid, and it occurs when the muscle or nerve responsible for keeping the lid raised stops working properly. Ptosis is a distinct medical condition with specific causes, and in some cases, it can have real consequences for vision and overall health. This blog will help you understand what ptosis is, what typically causes it, when it crosses the line from a cosmetic concern into a medical problem, and which type of doctor is equipped to evaluate it. If you or someone you love has noticed a change in eyelid position, understanding these basics can help you decide what to do next.
What Is Ptosis and How Is It Different From Simply Having Droopy Eyelids?
The formal medical term for ptosis is blepharoptosis, and it specifically describes the upper eyelid sitting lower than its normal position because the levator palpebrae superioris and/or Mueller’s muscle, the muscles that lift the lid, aren’t functioning properly. This is different from dermatochalasis, which refers to excess eyelid skin, which is a common aging change. Both conditions can make the eyes look smaller and feel heavier, or more tired, but they stem from different structural issues and call for different approaches to care.
Can Ptosis Affect One Eye or Both Eyes at the Same Time?
Ptosis can affect one eye (unilateral ptosis) or both eyes (bilateral ptosis). The two eyes can be equally droopy or can be asymmetric where one eyelid is lower than the other.
One important caveat: if drooping appears suddenly, pursue evaluation immediately. Sudden unilateral ptosis can be linked to neurological conditions such as Horner syndrome or third cranial nerve palsy due to a tumor or stroke. Sudden onset of bilateral ptosis can be due to myasthenia gravis, a disorder of the neuromuscular junction. With myasthenia gravis, drooping is usually worse in the afternoon or with prolonged use.
Is Ptosis Always Caused by Aging, or Can Younger People Develop It Too?
Ptosis generally falls into two broad categories. Congenital ptosis is present at birth, typically results from underdevelopment of the levator muscle and is typically bilateral. Acquired ptosis, on the other hand, develops later in life and can be unilateral or bilateral.
What Are the Most Common Causes of Ptosis in Adults Over 60?
For adults, the most frequent cause is what is known as involutional, or age-related, ptosis. This happens when the muscle/tendon stretches over time. Previous eye surgery, including cataract surgery, eye rubbing, eyelid trauma or contact lens wear can speed this process along.
Rarely, neurological conditions like Horner syndrome or third cranial nerve palsy, neuromuscular disorders such as myasthenia gravis, and mechanical causes like eyelid tumors or growths that add weight to the lid can be the cause of the eyelid drooping.
When Does Ptosis Become a Medical Problem?
When the eyelid droops it can partially or fully cover the pupil, which narrows the visual field. In adults, this can interfere with everyday tasks like driving and reading and can become a genuine safety issue. In children, even a partial obstruction during the early years of visual development can lead to permanent visual loss (amblyopia). Ptosis can also press on the cornea and subtly change its shape, sometimes resulting in astigmatism. Some patients unconsciously compensate by tilting their chin upward or raising their eyebrows to see past the drooping lid, a habit that can eventually lead to neck strain and recurring headaches.
Ptosis appearing suddenly, especially if accompanied by double vision, pupil changes, or pain, should prompt urgent evaluation, since this combination of symptoms can point to a neurological event.
What Type of Eye Doctor Diagnoses and Treats Ptosis?
Ptosis is typically first evaluated by an ophthalmologist. When the condition affects vision, you would be referred to a subspecialist known as an oculoplastic surgeon, a board certified ophthalmologist with additional fellowship training in plastic and reconstructive surgery of the eyelids and the structures around the eyes. A thorough workup for ptosis usually includes a comprehensive eye exam, an assessment of levator muscle function, external photos, visual field testing, and, depending on the findings, imaging or further testing to rule out neurological causes. The eyelid specialist will determine whether your symptoms are functional (medical problem) or a cosmetic concern. Dr. Kimberly Cockerham is an eyelid expert and oculoplastic surgeon with over two decades of experience caring for patients of all ages. She currently provides care at St Lukes in the Villages Brownwood location.
How Is Ptosis Treated?
Treatment for ptosis depends on several factors, including how severe the drooping is, what’s causing it, and how much levator muscle function remains. Mild cases that aren’t affecting vision often don’t require surgery. There is an FDA approved nonsurgical option for mild ptosis -oxymetazoline (Upneeq); it stimulates the eyelid muscles and results in improved eyelid position for approximately 8 hours. It is unfortunately not paid for by insurance.
Surgical correction is the most common treatment for visually significant acquired ptosis. This typically involves tightening the eyelid muscles, using either an external or internal surgical approach.
Risks of ptosis repair include bleeding, infection, asymmetry between the eyes, under- or overcorrection, need for additional surgery and worsening of dry eye symptoms. Dr. Cockerham will provide informed consent and answer your questions to help you determine if surgery is right for you.
The Bottom Line
Ptosis is a clinical condition with identifiable causes, and while it can certainly affect appearance, it becomes more than a cosmetic issue once it interferes with vision or daily activities or signals an underlying health concern. Whether the drooping developed slowly over the years or appeared seemingly overnight, having it evaluated by a qualified ophthalmologist is a sensible next step. If you or a family member has noticed changes in eyelid position, particularly if it’s starting to affect how you see, scheduling a comprehensive eye exam is a practical way to get clarity and peace of mind.
