External approach microsurgery of retinal dialysis.
OBJECTIVE
To explore the effect of external approach microsurgery in retinal dialysis.


METHODS
Consecutive 30 eyes of 28 patients with retinal dialysis were enrolled for this study. The progresses of the external approach microsurgery were following. Under the surgical microscopy, the preplacement of mattress sutures for buckling and/or encircling following retrobulbar anesthesia and scleral exposure, draining subretinal fluid, the cryotherapy of retinal breaks, checking the position of breaks on scleral buckle and gases injection were performed in turn.


RESULTS
After drainage of subretinal fluid, with scleral depression cryotherapy reaction around breaks could be observed clearly under the microscopy. All breaks were located on anterior slope of the buckle. Intraoperative complications were mild subretinal hemorrhage at drainage site and corneal epithelium exfoliation in 3 eyes, respectively. Postoperative complications were mainly secondary glaucoma and retinal redetachment. The one-operation reattachmentl rate was 96.7% (29 eyes), and the final reattachment rate was 100% after one eye had a second external approach microsurgery. The postoperative vision acuity (VA) was significantly better than the preoperative VA (chi(2)= 9.529, P< 0.01).


CONCLUSIONS
External approach microsurgery has favourable effect on the surgery of retinal dialysis.
