本文报告玻璃体内注气治疗黄斑裂孔性视网膜脱离32例32只眼,其中男性6例,女性26例;高度近视27例占84.3%;伴有赤道部裂孔者7例,其中3例为巨大裂孔;玻璃体内注入空气30例,注入过氟丙烷(C_3F_8)2例;有伴发破口者采用巩膜缩短术、硅胶外垫压术或硅压环扎术合并注气法封闭裂孔。注入空气量为1.5～2.0ml,C_3F_8为0.6ml,以术毕眼压在4kPa左右为准。必须注意术毕视力变化以防过量空气注入引起视神经缺血甚至血流中断。术后头俯位2～3天,使气泡顶压视网膜贴近色素上皮而重新粘合。本组一次手术治愈25例(78.1%),
This article reports intravitreal gas injection treatment of macular hole retinal detachment in 32 cases 32 eyes, 6 males and 26 females; 27 cases of high myopia accounted for 84.3%; with equatorial hiatus in 7 cases, of which 3 cases were huge holes ; 30 cases of air injected into the vitreous, perfluorinated propane (C_3F_8) injected in 2 cases; those who have associated with the scleral shortening scleral buckling, silicone padding or silicone compression cerclage combined with gas injection method to close the hole. The amount of injected air is 1.5 ~ 2.0ml, C_3F_8 is 0.6ml, with intraocular pressure in 4kPa or so prevail. Must pay attention to changes in visual acuity after surgery to prevent excessive air injection caused by ischemia or even interruption of blood flow. Head bent down after 2 to 3 days, so that the top of the bubble retinal pigment epithelial pressure and re-bonding. The group of a surgical cure in 25 cases (78.1%),
