A MULTIVARIATE-ANALYSIS OF ANATOMIC SUCCESS OF RETINAL DETACHMENTS TREATED WITH SCLERAL BUCKLING

One hundred and twenty-three preoperative, intraoperative, and postope rative variables were evaluated to assess their effect on anatomic suc cess of scleral buckling for retinal detachment. The relative importan ce of each variable was tested in a logistic regression equation. This equation identified ten significant variables for predicting the outc ome of retinal detachment surgery. The significant variables were: pre operative proliferative vitreoretinopathy (adjusted odds ratio, AOR, 1 3.60), previous buckle by G.F. Hilton (AOR = 8.03), total detachment ( AOR = 5.72), preoperative vitreous hemorrhage (AOR = 3.08), tension le ss than 10 mm Hg (AOR = 2.40), hemorrhagic complications (AOR = 2.62), previous buckles by others (AOR = 2.10), injection into the vitreous at surgery with either saline or balanced salt solution (AOR = 2.32) o r air/sulfahexafluoride (AOR = 7.06), and preoperative vision less tha n 0.3 (20/60 or worse) (AOR = 2.14). The number of cryopexy applicatio ns was specifically tested in the equation, but while significant in a univariate analysis, it was not found to be significant in the multiv ariate analysis.
