F6H8 as an intraoperative tool and F6H8/silicone oil as a postoperative tamponade in inferior retinal detachment with inferior PVR

Purpose. to evaluate the effectiveness and safety of perfluorohexyloctane (f6h8) for intraoperative flattening of the retina and of f6h8/silicone oil (so) 1000 cst as a postoperative tamponade for inferior retinal detachment with inferior proliferative vitreoretinopathy. methods. this is a retrospective review of 22 patients who underwent pars plana vitrectomy using f6h8 as an intraoperative tool to flatten the retina. at the end of the surgery a direct partial exchange between f6h8 and so 1000 cst was performed,tamponing the eye with different ratios of f6h8/so (70/30,60/40,50/50,40/30,and 30/70). anatomical and functional results and complications were evaluated over the follow-up period (mean 22.63 months). results. f6h8 was efficacious for intraoperative flattening of the retina. twenty-one of the 22 patients achieved a complete retinal reattachment. postoperative visual acuity (va) ranged from light perception to 20/70,with 72% of patients obtaining va better than 20/400. no emulsification/inflammation was observed whatever the ratio of f6h8/so used. with higher ratios of f6h8/so (70/30 and 60/40) cloudiness of the tamponade was observed. a transparent mixture was present with all the other ratios. conclusions. the surgical technique adopted is very simple and safe. the optimal f6h8/so ratio seems to be between 50/50 and 30/70. © 2014 gian marco tosi et al.
