非穿孔線維柱帯切除術(nonpenetrating lamellar trabeculectomy:NPLT)群10例13眼と従来の線維柱帯切除術(penetrating trabeculectomy:PT)群11例16眼の術後短期成績,術後早期合併症について比較した。NPLT群の術前,術後3か月,術後6か月の眼圧は25.1±6.0,13.8±3.1,13.8±3.2mmHg,PT群ではそれぞれ25.5±5.8,12.3±4.2,10.9±4.5mmHgであった。術後早期合併症ではNPLT群では少なく,特に浅前房はPT群では5例に対してNPLT群では1例も認めなかった。NPLTは眼圧下降効果では従来のPTよりやや劣る傾向にあったが,術後合併症が極めて少なかった。
We evaluated the early results following nonpenetrating lamellar trabeculectomy in 13 eyes and penetrating trabeculectomy in 16 eyes. The intraocular pressure (IOP) in the former group averaged 25.1 ± 6.0 mmHg before, 13.8 ± 3.1 mmHg at 3 months and 13.8 ± 3.2 mmHg at 6 months after surgery. The IOP in the latter group averaged 25.5 ± 5.8 mmHg before, 12.3 4.2 mmHg at 3 months and 10.9 ± 4.5 mmHg at 6 months after surgery. The early postoperative complication was less frequent in the former group. Shallow anterior chamber was absent in the former group and was present in 5 eyes in the latter group. Nonpenetrating lamellar trabeculectomy was slightly less effective regarding IOP control and was characterized by far lesser incidence of postoperative complications.
