Clinical Observation of External-route microsurgery in the Treatment of Rhegmatogenous Retinal Detachment

Objective:To observe the clinical efficacy of external-route microsurgery in the treatment of rhegmatogenous retinal detachment. Methods: Thirty-eight patients (38 eyes) of Rhegmatogenous retinal detachment, which were examined of location, size and scope of holes using the three-mirror contact lens before surgery, were performed external-route microsurgery. The visual acuity, intraocular pressure, retinal uveal reaction and the reattachment of retina were observed after surgery. Results: The data were collected as following: closure of retinal tears 36 eyes (94.74%), completely reattachment of retina 34 eyes (89.47%), subretinal fluid 2 eyes (5.26%), which were absorbed in 7-10 days, and improvement of visual acuity after surgery 28 eyes (73.68%). Among those, there were 2 eyes pad pressure ridge departures from the retinal hole, which were adjusted by reoperation. Conclusion: External-route microsurgery for rhegmatogenous retinal detachment is clear, convenient and effective.
