Methods: Twenty-eight patients with high myopia macular hole retinal detachment underwent vitreous cavity gas injection. The reduction rate, visual acuity and complications before and after operation were observed. Results: Twenty-eight eyes were successfully repaired by gas insufflation in 21 cases (75%). The improvement of visual acuity was 76.2%, while that of 3.8% was unchanged. No serious complications occurred. Conclusion: Vitreous cavity insufflation for macular hole with high myopia retinal detachment, safe, simple, repeatable, does not damage the residual vision, can be used as the preferred treatment of the disease
