中文摘要 | 目的:裂孔性視網膜剝離時,假如網膜下液體很多,常會增加鞏膜扣壓術的困難度及併發症。術前使眼球靜止,若可減少網膜下液體,將有利於手術之進行。 方法:我們總共收集了二十八位裂孔性視網膜剝離的病人,每位病人術前都接受十二小時以上的臥床休息併兩眼遮蓋,然後以超音波來比較網膜下液體量的變化。 結果:經過臥床休息兩眼遮蓋後,二十八位病人視網膜剝離的高度平均減少了百分之十七點一。視網膜裂孔小,以及沒有玻璃體牽引或慢性視網膜剝離變化者,網膜下液體減少的量較為顯著;而裂孔形狀、視網膜剝離的高度、年度、年齡、以及性別、則對視網膜下液體的變化較無影響。 結果:術前臥床休息併兩眼遮蓋,對某些裂孔性視網膜剝離的病患,可明顯減少網膜下液體,而裂孔大小、玻璃體牽引及慢性網膜剝離變化的有無,是影響網膜下液體吸收的重要因素。 |
英文摘要 | Backgorund: Bullous retinal detachment may be difficult to handle with higher operative complications. Preoperative immobilization of the eyes might reduce subretinal fluid and facilitate surgical procedures. Factors influencing subretinal fluid absorption were analyzed. Methods: Twenty-eight eyes with primary rhegmatogenous retinal detachment with preoperative binocular patching and complete bed rest for at least 12 hours were enrolled. Ultrasonography was performed before and after immobilization to estimate the reduction in subretinal fluid. Results: The amount of reduction diverged in cases with an average of a 17.1%decrease in the maximal height of detachment. Retinal detachments in patients with smaller breaks and without vitreal traction or chronicity showed more significant reduction of subretinal fluid than did those patients with larger breaks and with vitreal traction or chronicity. On theother hand, break shape, height of retinal detachment, age, and gender had no obvious effect on surbretjinal fluid change. Conclusions: Preoperative immobilization of the eyes reduces the subretinal fluid in selected cases, which can decrease operative complications. Break size, virtual traction, and chronicity are important factors affecting the absorption of subretinal fluid. |
