深层巩膜咬切孔的大小对远期疗效的影响

本文随访97例130眼深层巩膜咬切术的远期效果,将咬切1孔,孔大L5×1.5mm者与咬切2孔,孔大1.5×3mm者严格分层匹配,进行比较。结果发现大孔者成功率(96.2%)高于小孔者(85.5%),P<0.05,前者功能性滤过泡(91.7%)多于后者(68.6%),P<0.01,前者远期视力减退者(21.7%)亦少于后者(48.6%);2组并发症无明显差别。因此作者建议深层巩膜咬切术最好咬切2孔(1.5×3mm)以提高成功率。

The late result of subscleral sclerectomy of 130 eyes(97 cases) was studied. As the sclerectomy of larger size(1.5×3.0mm)was compared with that of smaller size(1.5×1.5mm), the two groups being strictly matched instratum, the 1.5×3.0 group had higher success rate(96.2%vs 85.5%,P<0.05),more functioning filtration blebs(91.7%vs 68.6%,P<0.01), and less eyes with visual acuityreduced after operation(21.7% vs 48.5%,P<0.05).Therewas no statistically significant difference in the incidenceof complications between these two groups. Accordingly1.5×3.0mm(was recommended as the size of subscleralsclerelfctomy instead of 1.5×1.5mm, so as to improvethe success rate.
