ABSTRACT

Objective: to determine the risk factors associated with recurrent retinal detachment in patients vitrectomized.
Methods: case-control study nested in a cohort. We included patients with a diagnosis of rhegmatogenous retinal detachment treated with vitrectomy for one year, with a six months follow-up. We monitored the presence of incident event in the emergency department, and the examination room. Statistical analysis was performed by descriptive statistics (median, minimum and maximum) and inferential statistics (X2 test, Cox regression, Kaplan-Meier).
Results: a population of 94 patients with a median age of 55 years (21-83) was analyzed. The silicone was the most widely used type of tamponade in 62 patients (66 %) and recurrent retinal detachment occurred in 19 cases (20 %). In the relation between the non-relapse group and the relapse group, the statistically signifi cant variable was the use of silicone (p = 0.05, OR = 0.03, 0.013-0.98), wich had a lower probability of recurrent detachment compared with the use of sulfur hexafl uoride (SF6 gas) (p = 0.012).
Conclusions: the use of silicone compared with the use of SF6 gas has shown to be a protective factor for recurrent retinal detachment; however, the choice of method of tamponade should be individualized for each patient.
