Hi. I'm online and happy to answer your question today.
I am glad to hear that your have had an extensive workup and everything has come back normal.
At this point, I do not believe that the problem is with your eyes but rather with your brain/mind.
Well I think it might be time for you to take a very difficult, and bold, step to see if you can get some relief. It seems obvious to me that your current doctors have reached the bottom of their bag of tricks and, yet, you are still having these problems.
It sounds like you have been receiving good care from very qualified physicians without any significant lasting improvement in your condition. At this point I think the best thing for you to do would be to gather up copies of all your medical records and travel to a large University Teaching hospital. At an institution like that you could be evaluated and treated by a team of sub-specialists who are at the cutting edge of their respective fields. The best thing about these large teaching hospitals is that consultations are available with Professors and leaders in their field by just walking a few steps down the hall.
The Mayo Clinic in Rochester, Minnesota is an excellent example of just such a place as this. That being said there are many excellent teaching hospitals all across the country and I am sure that there is one near you.
I am not familiar with the major medical institutions in Nigeria but If you could tell me what large city you live near and how far it would be possible for you to travel in seeking treatment I would be happy to look up some names for you. Of course, you could also ask friends and associates or check the internet yourself. Let me know what you would like to do.
What is the take home message here? I believe that with the correct therapy and the right doctor you can overcome this issue and get back to reading.
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. And please let me know if the rating system gives you any troubles. Thanks in advance, Dr. Rick MD FACS
I see that you are offline. I will switch to Q&A format. This format works a lot like 'text messaging' but an email is sent to each of us anytime something is posted to this thread. We can continue to work on your question there..... :)
