We wished to know if excision of artificially produced intravitreal vessels would cause bleeding and if the hemorrhage could be controlled by increasing the intraocular pressure. In 17 rabbit eyes, the distal end of several intravitreal blood vessels was excised and removed by the Peyman vitrophage. No significant bleeding occurred from the vessels in 13 eyes, and in the remaining four bleeding stopped after 30 seconds or less of increased intraocular pressure. In one month of observation after surgery, there was no evidence of delayed hemorrhage. Electron microscopy of several transected intravitreal vessels revealed that vessel constriction, platelets and fibrin strands contributed to the prevention of immediate and delayed hemorrhage.
我们想了解切除人工制造的玻璃体内血管是否会引起出血,以及通过增加眼压能否控制出血。在17只兔眼中,用佩曼玻璃体吞噬器切除并移除了几根玻璃体内血管的远端。13只眼中的血管未发生明显出血,其余4只眼在眼压升高30秒或更短时间后出血停止。术后一个月的观察中,没有延迟出血的迹象。对几根横断的玻璃体内血管进行电子显微镜检查发现,血管收缩、血小板和纤维蛋白束有助于预防即时和延迟出血。
