非穿透性小梁切除術聯合親水丙烯酸填充引流器植入治療開角型青光眼

目的探討非穿透性小梁切除術聯合親水丙烯酸填充引流器植入治療開角型青光眼的效果和降眼壓的機制,開發一種國產生物植入引流器.方法對16例(24祗眼)開角型青光眼行NPTS聯合親水丙烯酸填充引流器植入治療,術後隨訪2～6個月,平均4個月,分别進行眼壓、視力、滤過泡形態、視野等觀察.結果16例(24祗眼)術前平均眼壓(用藥後)22～30.39mmHg;術後2個月平均眼壓14.31～17.01mmHg,6個月平均眼壓15.02～18.52mmHg.結膜下形成滤過泡12例(18祗眼),占75%,均未出現嚴重并發癥,部分病例視力及視野較術前有所提高.房角檢查,均可見手術區小梁綱後有一减壓閥存在.結論NPTS聯合親水丙烯酸填充引流器植入治療開角型青光眼是安全有效的,與進口的填充材料療效相同.且價格低,是一種良好的鞏膜瓣下填充引流材料.

The open glaucoma treated with non-penetrating trabeculectomy combined with the implantation of drainage instrument with hydrophilic acrylic acid padding

Objective To discuss the effect and the mechanism of treating the open glaucoma with non-penetrating trabeculectomy Combined with the implantation of drainage instrument with hydrophilic acrylic acid padding and to develop it. Methods We operated the trabeculectomy on 16 cases (24 eyes) with open glaucoma, operative follow-up period of 2~6 months (mean 4 months), they were observed in the eye pressure, vision, filtering bled form, eye fields et al. Results In 16 cases (24 eyes), mean preoperative eye pressure postdrug, was 22~30.39 mmHg, mean postoperative eye pressure was 14.31~17.01 mmHg, mean eye pressure was 15.02~18.52 mmHg in six months. Filtering bleb appeared in 12 cases (18 eyes), making up 75%, without serious complications, and the vision and eye field in some cases was improved to some extent. Chamber angle examination; there was a decompression valve behand the trabecularism in the operative area. Conclusion The area of open glaucoma with NPTS combined with hydrophilic acrylic acid padding, is dangerous and effective. The efficacy is similar to which of the improved. It is quite cheap and a good padding and drainage materials under the scleral flap.
