To compare the effect of a long-acting (16% perfluoropropane [C3F8]) versus a short-acting (air) intraocular gas tamponade on visual outcome and macular hole closure rate after vitrectomy and intravitreal instillation of transforming growth factor-beta 2 (TGF-beta 2) on the macula.
Vitrectomy with removal of the posterior hyaloid fluid-gas exchange with instillation of TGF-beta 2 was performed in 15 eyes treated with air and 37 eyes treated with 16% C3F8 using identical surgical techniques (mean follow-up, 5.6 months).
The macular hole was closed successfully in 36 (97%) of 37 eyes treated with 16% C3F8 and in 8 (53.3%) of 15 eyes treated with air (P = 0.00007). The visual acuity improved by a mean of 3.1 lines on the Early Treatment of Diabetic Retinopathy Study chart for eyes treated with 16% C3F8 and 1.3 lines for eyes treated with air (P = 0.003).
A longer duration intraocular gas tamponade from 16% C3F8 gives a much higher rate of successful closure of macular holes and improved visual acuity using vitrectomy and TGF-beta 2 than does air.
比较长效（16%全氟丙烷[C3F8]）与短效（空气）眼内气体填塞对玻璃体切除联合玻璃体内注射转化生长因子-β2（TGF-β2）至黄斑区后视力预后及黄斑裂孔闭合率的影响。
采用相同手术技术，对15只接受空气治疗的眼睛和37只接受16% C3F8治疗的眼睛进行玻璃体切除，去除后玻璃体，进行液气交换并注射TGF-β2（平均随访5.6个月）。
16% C3F8治疗的37只眼中有36只（97%）黄斑裂孔成功闭合，空气治疗的15只眼中有8只（53.3%）黄斑裂孔成功闭合（P = 0.00007）。在糖尿病视网膜病变早期治疗研究视力表上，接受16% C3F8治疗的眼睛视力平均提高3.1行，接受空气治疗的眼睛视力平均提高1.3行（P = 0.003）。
与空气相比，16% C3F8提供的更长持续时间的眼内气体填塞，在玻璃体切除联合TGF-β2治疗时，黄斑裂孔成功闭合率更高，视力改善更明显。
