[Clinical risk factors for proliferative vitreoretinopathy after retinal detachment surgery].
OBJECTIVE
To identify the clinical risk factors for the development of severe proliferative vitreoretinopathy (PVR) after scleral buckling procedures for retinal detachment (RD).


METHODS
A retrospective study of 124 patients with rhegmatogeneus RD treated initially with buckling procedures, with either no PVR or with no PVR of grade C-l or less at initial examination was conducted. After surgery, severe PVR was defined as grade C-2 or worse. Univariate analysis and stepwise logistic regression evaluated the data relating to 34 statistical series (96 variables).


RESULTS
Severe PVR develop after surgery in 13 patients (10.48%). Seven significant predictive variables were identified: grade A preoperative PVR (p=0.005), detachment involving more than 2 quadrants (p=0.019), preoperative vitreous traction (p=0.002), intravitreal injection (p=0.046), scleral perforation (p=0.001), unsealed break (p=0.001), and postoperative vitreous traction (p=0.012).


CONCLUSIONS
The results indicate that in addition to the extent of detachment, and presence of preoperative inflammation or low grade PVR, iatrogenic problems also are important factors in the pathogenesis of severe PVR after surgery for RD.
