Nd: YAG laser iridotorny was performed as an initial procedure after acute angle closure glaucoma in 39 eyes between April 1993 and May 1995. Retrospective results showed that, following successful patent laser iridotomy, IOP was under control without any antiglaucoma medication in 11 eyes (28%). Eighteen eyes (46%) needed long term medications and 10 eyes (26%) required subsequent filtering surgery for intraocular pressure control. Duration of attack was associated with the need for antiglaucoma medicaiton or further surgery (Chi-Square, p<0.05). In 10 eyes who proceeded with filtering surgery, gonioscopy demonstrated peripheral anterior synechiae covered more than 75% of trabecular meshwork in 6 eyes (60%). The extent of peripheral anterior synechiae after Nd: YAG laser iridotomy is also significantly associated the successful result of laser iridotomy (Chi-Square, p<0.05).
