前房隅角小梁切除手術對青光眼之眼壓控制效果
Effectiveness of Trabeculectomy in Glaucoma
摘要
本報告提出86例，103眼，做隅角小梁切除手術後，追綜6個月以上之原發性青光眼眼壓控制效果成績。不併用青光眼治療藥物，其眼壓控制在19mmHg以下，成功者74.8%。此成功率與追綜期間，年齡及術後之結膜辨水皰形成良否有關聯。隅角開放性與閉塞性兩者之間似無成功率高低之差異。本手術仍然有各種合併症，較常遇到者為前房出血及前房形成不良而扁平。但此三種合併症之有否與手術成功率無關。本手術可說安全而有良好眼壓控制效果。

A follow up study over 6 months of 103 eyes in 86 patients with primary glaucoma subjected to trabeculectomy between 1976 and 1978 showed that intra-ocular pressure was controlled below 19 mm Hg in 74.8% without the aid of antiglaucomatous medication. A bleb formation of the conjunctival flap was noted in 84%. Among the failure eyes, the intra-ocular pressure elevated beyond 20 mm Hg by 3 months postoperatively in 57.7%. After 9 months the effectiveness on controlling the intra-ocular pressure seemed stable and reliable. The younger patients under the age of 40 showed lower rate of success than the olders, the former was 46.7% among 15 eyes, and the latter 97.5% among 88 eyes. Among those who developed a prominent conjunctival bleb, 18 among 19 eyes 94.7% showed successful control of the intra-ocular pressure. Among 49 eyes where the conjunctival bleb formation was recognizable, the rate of .sccess was 91.8%. Of 19 eyes where the conjunctival bleb was only of trace, the rate of success was 73.7%. Of 15 eyes where there was no conjunctival bleb, all failed. The level of the intra-ocular pressure remained favorably lower where the bleb formation of the conjunctival flap was more prominent. The method was not free of operative and postoperative complications. Among 118 operations hyphema was encountered in 22.9%, flattened anterior chamber in 9.3%, and hypotony below 9 mm Hg in 4.2%. The occurrence of hyphema and flattened anterior chamber did not show unfavorable influence on the effectiveness of the surgery.
