严重眼球破裂伤无光感眼合并角膜血染的手术治疗

目的 探讨严重眼球破裂伤无光感眼合并角膜血染的手术治疗效果，并分析相关因素。 方法 7例患者7只眼因严重眼球破裂伤无光感合并角膜血染接受2期临时人工角膜下玻璃体切割联合角膜移植手术。2期手术前7只眼均角膜血染，前房及玻璃体积血，视网膜脉络膜脱离。1期与2期手术间隔时间平均18d(12～21d)。手术前视力均无光感，眼压平均3 mm Hg(1mm Hg=0.133 kPa)(2～5 mm Hg)。随访平均时间12个月(6～30个月)。 结果 5只眼恢复光感以上视力，矫正视力从光感至0.05。视网膜复位5只眼(5/7)。眼压平均12 mm Hg(5～15 mm Hg)，明显高于手术前眼压(P＜0.05)。并发症包括一过性高眼压(1 只眼)，角膜新生血管(4只眼)，角膜排斥反应(4只眼)，眼球萎缩(2只眼)。 结论 临时人工角膜下玻璃体切割联合角膜移植手术是挽球严重眼球破裂伤无光感眼合并角膜血染的安全有效的方法。（中华眼底病杂志，2004，20：212-214）

Surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception

Objective To evaluate the effects of surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception, and analyze the relative factors. Methods Seven severely ruptured eyes of 7 patients with blood staining of cornea and non-light perception underwent second-stage penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis. All injured eyes had blood staining of cornea, hemorrhage in anterior chamber and vitreous, and choroidal and retinal detachment before the second-stage surgery. The average interval of the two surgical stages was 18 days (12-21 days). The preoperative visual acuity was non-light perception in all injured eyes with the mean intraocular pressure of 3 mm Hg (1 mm Hg=0.133 kPa) (2- 5 mm Hg). The mean follow-up period was 12 months (6-30 months). Results The postoperative visual acuity was better than light perception in 5 eyes with the best corrected visual acuity of light perception to 0.06. The retina was attached in 5 eyes (5/7). The mean postoperative intraocular pressure was 12 mm Hg (5- 15 mm Hg) which was significantly higher than the preoperative one (P<0.05). Postoperative complications mainly included temporary intraocular hypertension (1 eye), corneal neovascularization (4 eyes), cornea rejection (4 eyes), and ocular atrophy (2 eyes). Conclusion Penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis is a safe and effective method in treating severe ocular rupture with blood staining of cornea and non-light perception.
