AIM: To investigate the potential impact of lipidaemic and clinical factors on the development of proliferative vitreoretinopathy (PVR) following uncomplicated primary rhegmatogenous retinal detachment (RRD) surgery in nondiabetic individuals.
METHODS: This was a retrospective, single-center, case-control study of consecutive patients who underwent primary RRD surgery. The study group comprised 145 patients who developed PVR within 3y of follow-up, while the control group comprised 161 patients with RRD who did not develop PVR. Cox regression analysis was utilized to identify independent associations between various risk markers and the occurrence of PVR.
RESULTS: The mean age of patients was 52.31y (SD=13.29), and 54.25% (n=166) were male. The median time to PVR formation after surgery was 150d. Multivariate Cox regression indicated that cigarette smoking status [hazard ratio (HR): 0.43, 95% confidence interval (CI): 0.31-0.60, P<0.001], retinal detachment (RD) not involving the macula (HR: 0.52, 95%CI: 0.37-0.73, P<0.001), apolipoprotein A1 (ApoA1; HR: 1.01, 95%CI: 1.01-1.02, P<0.001) and apolipoprotein E (ApoE; HR: 3.81, 95%CI: 1.64-8.85, P=0.002) were independent predictors of PVR.
CONCLUSION: Apart from macular involvement and smoking, the lipidaemic factors ApoA1 and ApoE are risk factors of PVR after primary RRD surgery.
