AIM: To investigate the factors affecting reduction and vision recovery after minimally invasive scleral compression with RRD detachment.

METHODS: From December 2014 to October 2017, 296 cases(296 eyes)of incipient RRD patients in our hospital were selected as the research objects. All patients underwent minimally invasive scleral compression, the postoperative retinal reduction rate and BCVA were observed, and the factors that may affect the retinal reduction and visual recovery were analyzed.

RESULTS: A total of 272 eyes(91.9%)were successfully restored after minimally invasive postoperative scleral compression for the first time. Perioperative factors affecting retinal reduction include the number of holes, retinal detachment range and grade C1 PVR. At the follow-up of 6mo, 196 eyes(66.2%)had BCVA ≥0.4, and 100 eyes(33.8%)had BCVA <0.4. Duration of disease, preoperative BCVA, retinal detachment, and macular involvement were risk factors for postoperative BCVA(all P<0.05), while preoperative BCVA was an independent risk factor for postoperative BCVA recovery(P< 0.05).

CONCLUSION: Minimally invasive scleral extrascleral compression is effective in the treatment of retinal detachment due to simple aperture, with a high postoperative reduction rate. Early detection and early treatment are required for RRD patients.
