目的 :观察小梁切除术后持续性低眼压所致的黄斑病变。方法 :对 15例 (18眼 )原发性开角型青光眼行小梁切除术 ,术后前房形成 ,眼压持续 2周或 2周以上低于 1.33k Pa,出现视力下降 ,视网膜水肿 ,黄斑区皱褶 ,给予矫正低眼压治疗和营养神经治疗 ,临床观察 6～ 12月。结果 :低眼压纠正后 ,有 16眼黄斑皱褶消退 ,5眼视力提高 ,10眼视力不变。结论 :低眼压性黄斑病变的发生与患者的年龄、高度近视、眼局部长期应用抗青光眼的药物、抗代谢药物、糖尿病、高血压病和冠心病等因素有关 ,对年轻患者、高度近视患者术中应用抗代谢药物应慎重 ,一旦出现持续性低眼压性黄斑病变应尽早治疗。
Objective: To observe the macular degeneration caused by persistent low intraocular pressure after trabeculectomy. Methods: Fifteen patients (18 eyes) with primary open-angle glaucoma underwent trabeculectomy. The anterior chamber was formed and the intraocular pressure (IOP) was below 1.33 kPa for 2 weeks or more. Visual acuity, retinal edema, Macular area folds, given correction of low intraocular pressure and nutritional nerve treatment, clinical observation 6 to 12 months. Results: After correction of low intraocular pressure, macular fold of 16 eyes subsided, visual acuity increased in 5 eyes and visual acuity in 10 eyes was unchanged. Conclusions: Ocular macular degeneration is associated with age, high myopia, long-term use of anti-glaucoma drugs, antimetabolites, diabetes mellitus, hypertension and coronary heart disease in young patients, patients with high myopia Intraoperative antimetabolite drugs should be cautious, in the event of persistent low intraocular pressure macular degeneration should be treated as soon as possible.
