One hundred eyes of 100 patients in whom Tenon's cysts (TCs) developed in the early postoperative period following trabeculectomy with mitomycin C were retrospectively studied to determine their incidence, possible risk factors associated with their development, and the clinical course of the patients in whom they occurred. The incidence of TC formation was 29/100 (29%). Significantly more cysts developed in the men than in the women. There were no significant differences between those patients in whom TCs developed and those in whom they did not in terms of age, race, type of preoperative medications, mean preoperative intraocular pressure (IOP), prior argon laser trabeculoplasty, prior trabeculectomy, prior Tenon's cyst formation, or prior cataract surgery. The 29 patients in whom a Tenon's cyst developed had a mean follow up of 22.0 +/- 12.9 weeks, with a mean IOP at the last examination of 14.2 +/- 6.3 mm Hg (as compared with 20.7 +/- 8.3 mm Hg at the time of diagnosis). One patient required a repeat trabeculectomy with mitomycin C. Two patients required bleb needling, subsequent TC excision, and eventual seton placement. Of the remaining 26, 14 (54%) required no glaucoma medication for IOP control, 11 (42%) required one, and 1 (4%) required two.
对100例患者的100只眼睛进行回顾性研究，这些患者在丝裂霉素C小梁切除术后早期出现了Tenon囊肿（TCs），以确定其发生率、与囊肿发生相关的可能危险因素以及发生囊肿患者的临床病程。TC形成的发生率为29/100（29%）。男性发生囊肿的明显多于女性。在发生TCs的患者与未发生的患者之间，在年龄、种族、术前用药类型、术前平均眼压（IOP）、既往氩激光小梁成形术、既往小梁切除术、既往Tenon囊肿形成或既往白内障手术方面没有显著差异。发生Tenon囊肿的29例患者平均随访22.0±12.9周，最后一次检查时的平均眼压为14.2±6.3 mm Hg（诊断时为20.7±8.3 mm Hg）。1例患者需要再次行丝裂霉素C小梁切除术。2例患者需要进行滤泡针刺、随后切除TC并最终植入引流管。其余26例中，14例（54%）眼压控制无需使用青光眼药物，11例（42%）需要使用一种药物，1例（4%）需要使用两种药物。
