Photodynamic Therapy for Central Serous Retinopathy

I was diagnosed with central serous retinopathy a few months ago and when it didn't repair itself the Retina specialist recommended photodynamic therapy which is scheduled in a few weeks. I was not given much info on this procedure from him & want to be sure this is the best route to take. Anything you can tell me would be appreciated. I considered cancelling the procedure but was told it should be done sooner than later. How do I know I chose the right doctor?


PDT is the most effective treatment for central serous retinopathy. It is slightly modified from the version used in treating macular degeneration. The retina specialist typically will use either reduced fluence (ie reduced intensity of the laser beam used) or reduced duration PDT. This is effective, but associated with less scarring than conventional fluence and duration PDT. You will be advised to stay out of the sun for 2 days after the procedure. This refers to extended exposure to sunlight, not quick trips from indoors to your car, for example. If you are behind glass you are safe. It is the direct exposure to sunlight that can cause a sunburn. It is a little disturbing that you got the sense that doing the procedure is time sensitive. Not so. It makes no difference in the ultimate outcome if you are treated today, tomorrow, in a week, or in a month. It might make a difference if you waited many months. You should not feel hurried into a procedure, and it is a good idea to get a second opinion if you have doubts before embarking on elective surgery or laser.
