Possible Ptosis? Right Eyelid Drooping Over the Last 5 Months? (photo)

You certainly have right upper eyelid ptosis, but as Dr. Steinsapir has pointed out, your left eyebrow is slightly higher than your right eyebrow. This indicates you may be recruiting your left brow elevator [frontalis] muscle to help you see better out of your more dominant eye.

If you operate only on the right eye, this may diminish this drive and brow may drop a bit, revealing that the left eye is also droopy. Be prepared for this possibility. An oculoplastics consultation would be helpful for you.

See link below to find one near you.

While the right upper eyelid is the heaviest in the photos, there is compensatory brow elevation in both eyebrows but the left is lifted more than the right.  This suggests to me that both upper eyelid have ptosis but you compensate more for the left side which is likely your dominate eye.  You need to address with this a very experienced oculoplastic surgeon.  You can go on the ASOPRS (American Society for Ophthalmic Plastic and Reconstructive Surgery) website to find a highly qualified surgeon in your area.

Yes, you definitely do have right upper eyelid ptosis. Although most commonly it is involutional, meaning age-related relaxation of the muscle/tendon responsible for the lifting the upper eyelid, rarely could be due to other conditions. See an oculoplastic surgeon for evaluation and treatment (ptosis surgery).

First step is the diagnosis the cause on onset ptosis. Best to see an eye doctor and a neurologist for complete examination. 

  Ptosis as a condition of the upper lid  that can affect one eyelid or both eyelids.  ptosis results in amuscle weakness which when present, relaxes the  upper lid so that it   drops down across the black pupil part of the eye. Cosmetic blepharoplasty is performed for dermatochalasis, where extra skin and fat is creating a hooded or puffy look on the upper lids. Ptosis repair is best performed by oculoplastic surgeon,  whileupper blepharoplasty can be performed by an oculoplastic surgeon, plastic surgeon or facial plastic surgeon

It does appear that you have about 2 - 3 mm of upper eyelid ptosis on the right side.  You should be evaluated for this condition especially since it started, or you began to notice it only 5 months ago.  Your first visit should be to your ophthalmologist for a thorough eye exam this may be followed by a surgical consultation for correction.  

People who've had more noticeable ptosis as they got older usually had a small degree of ptosis which  they compensated for before the ptosis become progressively worse. As a physician, a new onset of ptosis always requires some type of medical and neurologic workup. We have to rule out some possible things that can be related to with ptosis being an early sign.

My recommendation is that you bring this attention to your medical doctor or see an ophthalmologist or a neurologist. You need to bring this to the attention of a physician so that the appropriate medical workup can be done and you can rule out any of the things that may need to be dealt with before you consider doing any type of corrective procedure.

When someone has ptosis, we do something called levator muscle dehiscence or levator muscle attenuation. In this procedure, the muscle called the levator muscle has a tendon called the aponeurosis that tends to thin and sometimes detach. When that happens, the eyelid droops .  We routinely perform a procedure called the levator muscle advancement, where something has fallen back so we bring it forward. This procedure is done with local anaesthesia and light sedation so that the person can actually cooperate. With this, we can maximize the appearance of the proximity of both of the eyes in terms of contour, height and shape.

I hope that was helpful and thank you for that question.
