Why is One Eye Bigger and 'Higher' Than the Other? (photo)

Review of your clinical history and
pictures suggest that youmight have a condition known as Graves disease. This
disease can cause a variety of changes that effect the eye. In some cases the
eyeball is actually enlarged by a condition known as exophthalmos. This
condition can also effect the eyelid, eye soft tissue, eye muscles, cornea and
even the optic nerve.

                  In
addition Graves disease can cause hyperthyroidism which can cause significant
systemic problems. Examples include insomnia,
hyperactivity, hand tremors, hair loss, excessive sweating, palpitations,
muscle weakness, weight loss, panic attacks, cardiac arrhythmias and elevated
blood pressure.

                  Your
symptoms and physical findings suggest a diagnosis of Graves disease. It’s
important that you undergo a comprehensive medical evaluation to address this
problem. It’s important that your hyperthyroidism and eye changes both receive
appropriate treatment. This may require an endocrinologist and an
ophthalmologist who specializes in this type of problem. 

Many different situations can lead to uneven eyelids. Some of these can be treated non-surgically and conservatively, even using some very advanced injection techniques with filler or very precise placement of Botox. Some situations truly do require surgery to resolve. 
It is important that you seek a consultation with an eyelid expert to delineate the exact cause and treatment options.
To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon.

#eyelid surgery for asymmetryPatients who would benefit from a
blepharoplasty include those who experience:#Asymmetry of the eyelids.

Excess skin or sagging of the upper eyelids (which can obscure
vision)

Excess
upper lid skin or hooding may be due to brow positionyour eyes have minimal and normal differences but see your PMD or ophthalmologist

From your photograph and physical symptoms it looks and sounds like Graves Disease. It is common in this condition for an eyelid to retract upwards giving the startled appearance. After 1 year of stable appearance, the eyelid can be repaired by an oculoplastic surgeon. Artificial tears may be needed to prevent dryness. See your internist for some blood tests including thyroid function.  

You have a very minor degree of asymmetry if your eyes, which is not uncommon at all. I would consider the degree of asymmetry to be within the normal range.  However, it sounds like you have some other issuers which should be looked into further by your primary care physician.

First you appear to have upper eyelid retraction.  This is a sign of an overactive thyroid gland.  This of course fits in with your other hyper metabolic symptoms including palpitations, anxiety, weight loss, and heat intolerance.  Your primary care physician will be able to assess these symptoms and evaluate the thyroid with blood tests.  The treatment is to control the thyroid.  Your eye changes are mild and may less with time.  First start getting the  thyroid checked out.  

No two eyes are symmetric.  With a split mirror, most people will note asymmetries. 

Regarding your situation, temporary changes can of course occur either spontaneously with changes in muscle activity, or with certain medications, injections such as Botox and of course surgery.

Your photograph shows your right eye and brow to be a bit more open/higher which looks like a Botox effect.  If you haven't had a Botox injection, don't panic.  You can consult with a plastic surgeon or opthalmologist who can reassure you and if appropriate, consider a simple treatment to improve the asymmetry.

      

It seems there are other potential medical issues that need to be looked at, it may have an organic cause that can be addressed (palpitation, weight loss etc). Your eyes seem relatively symmetrical to me but metabolic issues that may coincide with your eyes could be thyroid issues and you should visit your local doctor to address all the symptoms at play.
Wish you the best in your journey,

The problems you describe should be examined by your primary care doctor to investigate any issues with your thyroid or general health.  The eyes can be affected in some disorders that cause thyroid problems and this can be evaluated with an orbital specialist.

I would talk to your primary care physician and get a full evaluation. Secondarily I would see an ophthalmologist or Oculoplastics and orbital specialist to measure your eyelid width to assure you are not dealing with a new onset eyelid retraction or proptosis which could necessitate treatment.
