青光眼合并外伤性晶状体悬韧带断裂非穿透性小梁切除术的临床观察

Clinical evaluation of non-penetrating trabeculectomy for treatment of glaucoma with lens part of suspensory ligament rupture

目的观察非穿透性小梁切除术治疗青光眼合并外伤性晶状体悬韧带部分断裂的效果。方法 8例（9眼）开角型青光眼合并晶状体悬韧带部分断裂采用非穿透性小梁切除术,术中联合应用丝裂霉素,观察疗效,术后1、2、7、14 d,1、2、3月,以后每3月进行视力、眼压、裂隙灯显微镜及检眼镜检查。结果术前平均眼压（30.98±12.30）mmHg,术后1 d平均眼压（6.08±2.65）mmHg,经3-24月随访平均眼压（14.38±4.24）mmHg。均未出现术后浅前房、炎症、前房积血、晶状体悬韧带断离范围扩大、玻璃体脱入前房量增大等并发症。结论非穿透性小梁切除术治疗青光眼合并晶状体悬韧带部分断裂更安全有效。

Objective To evaluate the clinical effect of non-penetrating trabeculectomy in treating glaucoma with lens part of suspensory ligament rupture. Methods 9 eyes of 8 open-angle glaucoma patients with lens part of suspensory ligament rupture were treated with non-penetrating trabeculectomy augmented with mitomycin,during the operation.The vision,intraocular pressure,slit-lamp microscopy and ophthalmoscopy were examined on the postoperative 1,2,7,14 days,1,2,3 months and then every 3 months. Results The mean preoperative intraocular pressure（IOP） was 30.98±12.30 mmHg.The mean postoperative IOP was 6.08±2.65 mmHg in 1 day and 14.38±4.24 mmHg in follow-up of 3-24 months.There has no complications,such as postoperative shallow anterior chamber,inflammation,hyphema,further expansion of lens suspensory ligament rupture and increasing of vitreous taken into the anterior chamber. Conclusion Non-penetrating trabeculectomy is more safe and effective for treatment of glaucoma with lens part of suspensory ligament rupture.
