Clinical experience of external -route retinal detachment surgery under a surgical microscope.

Objective: To evaluate the efficacy of external-route retinal reattachment surgery under a surgical microscope.

Methods: A total of 86 patients (86 eyes) with rhegmatogenous retinal detachment underwent external-route retinal detachment surgery under a surgical microscope. Drainage of subretinal fluid, transscleral cryotherapy, scleral buckling, and intravitreal injection of gas were performed intraoperatively.

Results: Among 85 patients, 81 achieved postoperative retinal re-attachment after the first surgery and 5 after two surgeries. The visual acuity was elevated in 67 patients, unchanged in 15, and decreased in 4.

Conclusions: External-route retinal reattachment surgery under a surgical microscope is a convenient procedure for physicians to master and worthy of widespread application in clinical settings.
