AIM:To observe, analyze and compare the effect of minimally external surgery under microscopy and traditional external surgery on the treatment of non-complicated rhegmatogenous retinal detachment.

METHODS:The clinical data of 53 patients with 53 eyes of non-complicated rhegmatogenous retinal detachment in our hospital was analyzed retrospectively, of which the minimally external retinal detachment surgery under microscopy was performed in 25 patients with 25 eyes of non-complicated rhegmatogenous retinal detachment(the research group), and the traditional external retinal detachment surgery was performed in 28 patients with 28 eyes of non-complicated rhegmatogenous retinal detachment(the control group). All surgeries were performed by the same surgeon, and the clinical efficacy and complications of the two groups were compared and analyzed.

RESULTS: In postoperative hole closure, there was no significant difference in the primary rate of reattachment of the retina between the two groups(P>0.05). There was a statistically significant difference in postoperative complications between the two groups(P<0.05). The best corrected visual acuity after surgery was better than that before surgery in both groups. There was no significant difference in the increase of postoperative visual acuity between the two groups(P>0.05). There was a statistically significant difference in operative time between the two groups(P<0.05).

CONCLUSION: The effect of minimally external retinal surgery under microscopy and traditional external retinal surgery is similar in the treatment of non-complicated rhegmatogenous retinal detachment, but the minimally external retinal surgery has the advantages of shorter time, less damage and fewer complications.
