I was diagnosed with DRY AMD 14yrs ago and although it has progressed some over that time it has not yet reached the WET stage and hope fully won't for a few more years. With the onset of WET AMD one has to start having injections which can be quite expensive. Expense wise one needs to check out different eye hospitals for comparisons. I have three monthly tests done and the 4000bht cost is comparable to back home. However when i compared the cost of the injections the prices differed considerably. Eye hospitals in Bangkok were charging between 80,000/100,000 per injection, where as the Khon Kaen eye hospital which has a great reputation, where i go, charges 25,000bht per injection which again is on par with what it would cost me back home if i needed them.
So If you are diagnosed with AMD you need to check out first a good eye hospital with good service and second one where you are not going to be ripped off. I used to go to the Buriram government hospital until the head Ophthalmologist was promoted to a bigger hospital and was replaced with a female who can speak English but refuses to and only speaks in Thai to my wife. I did not take too kindly to this and told her to shove everything where the sun don't shine and started going to Khon Kaen where they speak good English and treatment is good.
I hope this helps some people somewhere along the line.
