Abstract
While hypotony maculopathy is an important potential complication of filtering surgery, its occurrence can be minimized by careful intraoperative adjustment of the scleral flap resistance and/or the use of a valve-like sclerocorneal wound construction. Furthermore, it can be reversed and the vision restored in nearly all cases by the use of the "two sets of sutures procedure," provided that the repair is done within 6 months of the onset of the condition, with only a small risk of loss of bleb function.
