We reviewed 112 consecutive cases of retinal detachment associated with grade C-1 proliferative vitreoretinopathy (PVR) to assess the initial location of the full-thickness retinal folds. A total of 47 eyes had PVR preoperatively, and 65 eyes demonstrated PVR postoperatively. Of the eyes affected preoperatively, 29 (56%) developed PVR in the inferior retina, as did 58 (74%) of the eyes affected postoperatively for a total of 87 eyes (67%). Eyes treated with cryoretinopexy had a higher incidence of PVR in the inferior retina (87.5%) than did those undergoing diathermy (57.6%) or photocoagulation (80%). Our findings suggested that the location of PVR may be influenced clinically by gravity. This tendency was more apparent after surgery, especially after cryoretinopexy, than preoperatively.
我们回顾了112例连续的与C-1级增殖性玻璃体视网膜病变（PVR）相关的视网膜脱离病例，以评估全层视网膜皱褶的初始位置。共有47只眼术前存在PVR，65只眼术后出现PVR。术前受影响的眼中，29只（56%）在视网膜下方出现PVR，术后受影响的眼中有58只（74%）也是如此，总计87只眼（67%）。接受冷冻视网膜固定术治疗的眼在视网膜下方发生PVR的发生率（87.5%）高于接受透热疗法（57.6%）或光凝术（80%）的眼。我们的研究结果表明，PVR的位置在临床上可能受重力影响。这种趋势在术后比术前更明显，尤其是在冷冻视网膜固定术后。
