Purpose:

To evaluate the use of perfluoropropane gas (C 3 F 8) versus silicone oil (SO) for retinal detachment secondary to macular hole in patients with high myopia and posterior staphyloma.

Methods:

In a retrospective study, 30 eyes of 30 patients underwent pars plana vitrectomy, and C 3 F 8 (17 patients) or SO (13 patients) tamponade; internal limiting membrane peeling was performed successfully at the first surgery in 23 patients. High-density silicone oil tamponade was used for reoperations.

Results:

The mean values of patients' characteristics were as follows: age, 57.7 years; axial length, 29.02 mm; spherical equivalent refraction,− 15.40 diopters; initial best-corrected visual acuity, 2.35 logarithm of the minimum angle of resolution; final best-corrected visual acuity, 1.59 logarithm of the minimum angle of resolution. In C 3 F 8 group, best-corrected visual acuity significantly improved (P< 0.001), passing from 2 …
