雅鉻雷射虹膜穿孔術於急性隅角閉鎖性青光眼的臨床結果

Result of Nd: YAG Laser Iridotomy in Acute Angle Closure Glaucoma

摘要


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).
