Variation of technique of episcleral sponge placement: effect on scleral indentation for retinal detachment repair.
Seventy-eight 5 mm silicone sponges were sutured to autopsy eyes using various techniques, and resulting scleral indentation was compared to a control series. Indentation was decreased by suture separation narrower or wider than 8 mm, short suture passage, loose sutures, high intraocular pressure, and partial thickness sponges. Increased indentation resulted from excessively tight sutures and low intraocular pressure. No change was produced by variation of sponge stretch or lengthening scleral suture passage. Lateral adjustability of sponge position was gained when wide suture separation was used.
