SLT was the subject of a symposium at the recent ESCRS in Paris.
The important outcomes of this were that it is now understood that SLT is not an all or none phenomenon. That is to say, it was thought that once it had been performed, whatever effect it produced that was it. It was thought that if there was only a less than optimal result, then additional medication was required. It is now known that if there a reasonable pressure lowering effect but not to target pressure then further SLT would produce an additive, further lowering. Further it is also known that the amount of SLT required is less than previously thought at each sitting. It is also apparent that a full 360 of SLT produces a greater pressure lowering effect than say only 180.
Full discussion as well as a round of of interesting presentation from the meeting will shortly follow in a full report.
