Purpose:To report long-term visual outcome of vitreous surgery for diabetic macular edema. Cases:This retrospective study included 351 eyes of 239 patients who received vitreous surgery by one surgeon during an 8-year period. All the eyes had diffuse diabetic macular edema. Thickening or detachment of posterior hyaloid membrane was consistently absent. Panretinal photocoagulation had been performed on 324 eyes(92.3%). Results:There was no difference regarding preoperative characteristics or final visual outcome between 237 eyes that could be followed up for 5 years or longer and 81 eyes followed up for less than 5 years. There were significant differences regarding age,HbA1c,hematocrit,nephropathy,and visual outcome between 33 eyes who died within 5 years of surgery and the other 318 eyes. There was no difference between visual acuity one year after surgery and final visual acuity. Postoperative visual acuity either improved or remained the same in about 80% in each of three groups. Conclusion:Vitreous surgery was effective for diabetic macular edema regarding long-term visual acuity.
