The clinical evaluate external route surgery of retinal detachment under surgical microscope

To evaluate the methods and the outcome of the retinal detachment surgery under surgical microscope. Twenty-one consecutive cases of the rhegmatogenous retinal detachment were enrolled in this study. All received retinal detachment surgery under microscope. Location the retinal breaks, the drainage of subretinal fluid with diathermy acupuncture and retinal cryopexy through sclera were performed under surgical microscope. Buckling and or circling were performed in six cases. All the patients were followed up three to nine months. The reaction of retinal cryotherapy was seen clearly under the microscope. And the observation of cryotherapy and the location of retinal breaks were not affected by mild media opacities. No severe complication appeared. Twenty cases got complete retinal reattachment. One eye got reattachment after an additional scleral buckling. The visual acuity were improved in all cases, The visual acuity was better than 0.3 in 15 eyes (71.42%). It appeared to be simple, convenient, easy observabl
