外傷性虹膜囊腫之手術治療－二病例報告
Surgical Treatment of Traumatic Iris Cyst-Two Cases Report
摘要
臨床上治療外傷性虹膜囊腫可探雷射光凝固法，冷凍法，使囊腫萎縮；或經由手術方式切除囊腫。基於雷射或冷凍治療常有合併症且無法根治，本篇報告兩例外傷性虹膜囊腫之手術療法。兩例分別為30歲男性及13歲女性；前者合併有結膜囊腫及角膜瘻管，我們施予手術切除結膜及虹膜囊腫，併施自體鞏膜移植及結膜瓣覆蓋手術；後者將虹膜囊腫切除併施虹膜整型術。兩病例約接受兩年以上的術後定期追蹤檢查，結果顯示兩病例均無任何虹膜囊腫復發的跡象，且視力均獲得良好的矯正，此外亦無白內障或青光眼等術後併發症的產生。切除之虹膜囊腫病理報告兩例均為未角質化多層為平上皮組織，類同於結膜或角膜上皮組織。以目前眼科儀器，器械及技術之進步，手術切除虹膜囊腫為一可行且根本之治療方法。

Traumatic iris cysts can be treated by means of cryotherapy, chemical agents, radiation, laser photocoagulation or surgical excision. Although laser photocoagulation is a noninvasive therapy, many unacceptable complications or frequent recurrence have been reported. We reported two cases of traumatic iris cysts treated by surgical block excision. Case 1, a 30-year-old man, had a traumatic iris cyst complicated with conjunctival cyst and corneal fistula. Excision of the conjunctival cyst and sector iridectomy of the iris cyst was performed then tectonic autologous scleral graft and conjunctival flap were applied. Case 2, a 13-year-old girl, sector iridectomy and iridoplasty were applied to remove the iris cyst completely. We have followed these two cases for more than two years. Both cases have kept the best corrected visual acuity, besides, no evidence of any sign of cystic recurrence or complications such as cataract or glaucoma were noted. Surgical block excision of traumatic iris cyst is the preferred treatment and affords the most effective in long-term cure.
