Advantages / Purpose:

To study the efficacy of endotamponade of inferior breaks by weak expanding concentration of perfluoropropane and additional gas tamponade in early postoperative period, if it is necessary.

Methods:

62 patients (63 eyes), 30 male (48,4%), 32 female (51,6%) with rhegmatogenous retinal detachment, PVR grade A: 16 eyes (25,4%), grade B: 39 eyes (61,9%), grade C: 8 eyes (12,7%), macula-on: 7 eyes (11,%), macula off: 56 eyes (89,9%) with inferior breaks were observed. The type of breaks: horse shoe tears: 39 eyes (61,9%), horse shoe tears + atrophic holes: 42 eyes (38,1%); retinal detachment with giant tears and dialyses was excluded. All patients underwent vitrectomy, fluid-gas exchange, and gas tamponade with weak expanding concentration C3F8. In 16 eyes vitrectomy was combined with circumferential buckle. In early postoperative period the amount of gas bubble in vitreous cavity was evaluated and in 39 patients (61,9%) an additional gas tamponade was performed. In early postoperative period retinal reattachment was achieved in all cases. In postponed period (5 to 6,5 months) after single operation retina attached: after primary vitrectomy: 86,5% (32/37 eyes), after vitrectomy combined with circumferential buckle: 93,7% (15/16 eyes), redetachment after scleral buckling 100 (4/4 eyes), in whole 89,8% (56/63 eyes).

Effectiveness / Safety:

This is an example of high efficacy of endotamponade of inferior breaks with weak expanding concentration C3F8 and additional gas tamponade in early postoperative period, if it is necessary.
