Purpose:To compare the results of vitrectomy with those of scleral buckling in patients with rhegmatgenous retinal detachment (RRD) due to posterior flap tear. Methods:During the period of January 1999 and December 2000, 62 patients(62 eyes) underwent operations because of RRD due to flat tear located on or posterior to the equator. 43 eyes underwent scleral buckling while the remaining 19 eyes received vitrectomy. Follow-up period was at least 3 months. Patients with macular hole retinal detachment or proliferative vitreoretinopathy were excluded. Results:1) The primary attachment rate was 96.8% in total. The rate was 94.7% and 97.7% in patients with scrleral buckling and vitrectomy, respectively. 2) Final attachment rate was 100% in both procedures. 3) Improvement of visual acuity more than 2 lines in patients without macular detachment was show in 57.1% and 11.1% after vitrectomy and scleral buckling, respectively, 83.3% in vitrectomy and 81.3% in scleral buckling in patients with macular detachment. 4) Deterioration of visual acuity in patients without macular detachment was 14.3% and 3.7% in vitrectomy and scleral buckling, respectively, 8.3% with vitrectomy and 6.3% with scleral buckling in patients with macular detachment. 5) Complications included epiretinal membrane in 5 of the eyes which underwent vitrectomy, temporary ocular hypertension and dysfunction of eye movement in 4 and 3 of the eyes in scleral buckling, respectively. 6) Although redetachment due to newly occurred retinal break was seen in 5 eyes in patients with scleral buckling, this was not encountered in cases with vitrectomy. Conclusion:Final attachment rate and prognosis of visual acuity in vitrectomy is equal to that in scleral buckling, although the primary attachment rate was higher in scleral buckling. Vitrectomy is superior to scleral buckling in terms of less occurrence of redetachment. Epiretinal membrane which complicates in vitrectomy needs further innovation.
