目的 :探讨老年性白内障膨胀期继发性青光眼的手术时机、手术方式、手术并发症。方法 :对 2 1例 2 2只眼行单纯白内障手术 3只眼 ,白内障手术联合抗青光眼手术 19只眼 (其中小梁切除术 17只眼 ,周边虹膜切除术 2只眼 ) ,一期植入人工晶状体 2 0只眼。结果 :术后 2 1只眼眼压正常 ,占 85 4 5 % ,术后视力均较术前明显提高 ,术后视力≥ 0 3者占 4 0 91%。结论 :老年性白内障膨胀期继发性青光眼 ,根据发作时房角是否开放选择恰当的手术方式可以提高视力及控制眼压 ,持续高眼压引起的视神经萎缩是术后视力低下的主要原因 ,强调膨胀期白内障手术是预防老年性白内障膨胀期继发性青光眼的重要措施。
Objective: To investigate the operation timing, operation method and complications of secondary glaucoma in senile cataract. Methods: Twenty - one eyes of 21 eyes with cataract were treated with cataract surgery. There were 19 eyes with cataract surgery combined with anti - glaucoma surgery (17 trabeculectomy and 2 peripheral iridotomy) 20 intraocular lenses. Results: The intraocular pressure was normal in 21 eyes (85.4%). The postoperative visual acuity was significantly higher than that before operation. The postoperative visual acuity ≥ 0 3 accounted for 4 0 91%. CONCLUSIONS: Secondary glaucoma in senile cataract may be the main cause of postoperative visual acuity (OSA) due to persistent ocular hypertension. According to whether the anterior chamber angle is open at the time of attack, the proper surgical methods can improve the visual acuity and control the intraocular pressure. Expansion cataract surgery is an important measure to prevent secondary glaucoma in senile cataract.
