| Abstract |
|
The retrospective study of 231 eyes which were underwent the vitrectomy for the proliferative diabetic retinopathy was done. The purpose of this study was to identify the factors associated with visual prognosis and to understand the clinical features of traction-rhegmatogenous retinal detachment in diabetic retinopathies. The functional outcome of vitrectomy in these group revealed 44.6% of visual improvement, 40.3% of visual constancy and 15.1% of visual deterioration. Anatomically, 55.8% of eyes in these study showed retinal attachment and clarity of ocular media, postoperatively. The preoperative factors associated with visual outcome were vitreous hemorrhage land retinal detachment. The postoperative factors were hyphema, iatrogenic break formation and rubeosis iridis. Preoperatively and intraoperatively, retinal breaks were found in 43 eyes among 142 eyes of retinal detachment. In 43 eyes, 39 eyes showed only one break. The site of retinal breaks was majorly at posterior pole and the shape of breaks showed no difference between them in frequency. Our clinical data proved that the extent of traction rhegmatogerious retinal detachment was larger than pure traction retinal detachment which has a tendency to be localized at posterior pole. The leading complication after operation was lens opacity(19.3%). |
