THC:YAG laser sclerostomy: the resident experience.

Retrospective review of 14 consecutive THC:YAG laser sclerostomies done without the use of anti-metabolites revealed a uniform closure of the filtering bleb within 6 months of follow up. Also, the sclerostomy site was closed by iris or fibrous tissue. Based on these findings, I recommend that the present THC:YAG laser sclerostomy protocol be altered to allow for antimetabolite usage, prevention and treatment of iris prolapse, and control of intraocular inflammation.
