Objective To compare the efficacy between intravitreal gas injection alone and pars plana vitrectomy (PPV) with intraocular gas tamponade in treating retinal detachment due to macular hole in high myopes.

Methods 24 eyes of 24 patients with retinal detachment owing to myopic macular hole were included in this prospective, randomized controlled study. The patients were randomly assigned to undergo intravitreal perfluoropropane (C3F8) gas injection (group A) or vitrectomy with intraocular C3F8 gas tamponade (group B). Complete ocular examination included best-corrected visual acuity, intraocular pressure,slit-lamp biomicroscopy, color fundus photography, ultrasound examination, and optical coherence tomography at baseline and every 3 months after the surgery. The longest follow-up time was lasted to 3 years after operation.

Results The retinal reattachment rates and the postoperative best-corrected visual acuity between group A and B was not significantly different (P>0.05). But the cost between two groups was significantly different (P<0.01).

Conclusion Intravitreal C3F8 gas injection alone was a safe, effective and low cost way in treating retinal detachment owing to macular hole in high myopes.
