What can cause bulging in one eye? (photos)

You need an actual workup by a real doctor.  I recommend seeing a general ophthalmologist or oculoplastic surgeon.  Unless there has been change over time, this could be something as simple as the axial length of the eye.  Near slight eyes are larger than far sighted eyes on average.  It could be thyroid eye disease which is a very common cause of one eye being more prominent than the other.  Bottom line, you need to see the right doctor and get to the bottom of this and it is not necessarily anything scary.

There are multiple reasons why one eye is bulging including genetic, thyroid eye disease, tumor, etc. If this is something recent and progressive, best to see an oculoplastic specialist soon. Treatment depends on the cause.

There are many things that can cause one eye to bulge.  IT the bulging is progressive it can be a sign of a thyroid disorder.  In any event you should see an oculoplastic surgeon who specializes in these types of orbital disorders.  They can often be treated but the first step is getting to the cause.

Thank you for your question. The situation you describe can be related to many things. You say that you have a history of hypothyroidism and thyroid related eye disease is by far the most common cause of bulging of one or both eyes. The fact that pressing on one side causes pain while not the other is also significant. There are many other causes of your symptoms. You need to see an Oculoplastic surgeon. A doctor in this specialty is best trained to evaluate the eye and surrounding structures from both a cosmetic standpoint and well as evaluating for disease that may be causing your problems. They will examine you and almost certainly obtain a C-T scan or MRI to evaluate the eye and orbit. Good luck and please have this evaluated soon.

Your symptoms indicate you need to see an ophthalmologist (an MD) and the sooner the better. Don't neglect this!
