When you say you have been to many "eye doctors," does that include a retinal specialist? Central serous retinopathy can be diagnosed with a dilated retinal exam or fluorescent angiography, though if this were the case it COULD have showed up on a standard dilated exam... Many, many possibilities. If you haven't been to a retinal specialist, you should go to one.
im in the medical field, with a similar problem. You might have a tear duct obstruction.
Have you ever had trauma to your eye/face?
Have you ever had a "needle in your eye?"
that is; a needle placed in your tear duct, by a physician and flushed with saline(salty)solution that you would taste in the back of your throat? Has this test been done during your multitude of doctor visits?
have you had a CT scan of your sinuses?
have you had pus, milky white discharge, or compromised, "fuzzy" vision?
are you "dry eyed" after sleep, but "tearing" during the day? burning and pressure?
what are your symptoms, treatments? do these sound familar?
wondering
all of that is possible. i never know how to answer the 'i've been to three doctors and no one can find anything wrong with me' questions.
i dont know whats wrong, either. sorry. yes, if you still have symptoms and are unsatisfied with your previous doctors, then go to another one.
