Abstract |
In 11(64.7%) of 17 eyes treated by intravitreal gas injection, the retinas were successfully attached during follow-up period that ranged from 12 to 39 months. Group I(detachment limited to the perimaculararea) patients need more frequent gas injection than group II(detachment extending to equator), but success rate of group I(83.3%) is higher than group II(66.7%). Group III(detachment with peripheral retinal break) patients are not successful by gas injection only. In the succesful eyes, macular holes are not visible, but "window defects" are present on FAG. The relative scotomas improve. Recurrent detachment cases(31.3%) are associated with posterior staphyloma, peripheral retinal break and trauma. Time of late recurrences ranged from 4 to 13 months postoperatively(mean: 7 months). |
