玻璃体切除后,偶发浓厚片状视网膜前出血存留于黄斑区和后极部,作者用改良的Machemer去除玻璃体积血的方法除去之。玻璃体切割器的切割头从眼内撤出,用一个连接输液瓶的38mm长21号针头经原巩膜切口插入眼内。将原切割时用的注入管接头拔掉,成为血和等渗溶液混合液的出口。用等渗盐水冲洗一短时期就可去除视网膜前出血。为防止冲洗时水流冲力形成视网膜破孔,针头不宜与视网膜太近,压力不可太高。作者用这项技术为7个病人去除视网膜前出血,而无不良后果。附图:
After vitrectomy, occasional thick sheet retinal hemorrhage remains in the macula and posterior pole, the authors use a modified Machemer removal of vitreous hemorrhage removed. The vitrectomy head was withdrawn from the eye and inserted into the eye via a primary scleral incision using a 38 mm long 21 gauge needle connected to an infusion bottle. The original cut with the injection pipe unplug the connection, as a mixture of blood and isotonic solution outlet. Rinse with isotonic saline for a short period of time before retinal hemorrhage can be removed. In order to prevent flushing water flow to form a retinal hole, the needle should not be too close with the retina, the pressure can not be too high. The authors used this technique to remove pre-retinal hemorrhage in 7 patients without adverse effects. Figure:
