Experience with external sponge buckles for the treatment of retinal detachment has led to a preference for radial placement of the sponge. More retinal holes, particularly large horseshoe breaks, can be closed effectively with radially oriented buckles than with limbus parallel ones; limbus parallel buckles often were complicated by "fish-mouthing" of the breaks and leaking radial folds. A radial orientation of the buckle averts this complication. The geometry of retinal detachment and scleral buckling reveals the origin of "fish-mouthing" and radial folds and why radially oriented buckles prevent this complication.
使用外部海绵扣带治疗视网膜脱离的经验表明，更倾向于将海绵呈放射状放置。与平行于角膜缘的扣带相比，呈放射状排列的扣带能更有效地封闭更多的视网膜裂孔，尤其是大的马蹄形裂孔；平行于角膜缘的扣带常常因裂孔处出现“鱼嘴样”改变和放射状折叠渗漏而变得复杂。扣带呈放射状排列可避免这种并发症。视网膜脱离和巩膜扣带术的几何学揭示了“鱼嘴样”改变和放射状折叠的起因，以及为什么呈放射状排列的扣带可预防这种并发症。
