Abstract Giant retinal tear-associated rhegmatogenous retinal detachment (GRT–RRD) presents a significant surgical challenge. Trauma stands out as one of the risk factors. This retrospective case series aims to assess the outcomes of GRT–RRD patients treated with pars plana vitrectomy (PPV), distinguishing between non-trauma and blunt ocular trauma cases. The medical records and relevant retinal imaging of 60 GRT–RRD patients undergoing PPV and followed with a mean (SD) of 21.2 (13.4) months were reviewed (47 were non-trauma-related and 13 were trauma-related). Both the non-trauma and trauma groups exhibited comparable distribution of proliferative vitreoretinopathy grade (P = 0.067). Following the primary operation, there was no statistically significant difference in the proportion of patients achieving single surgery anatomical success between the non-trauma group (27/47 patients, 57.5%) and the trauma-related group (9/13 patients, 69.2%) (P = 0.534). At the final follow-up, 17 patients remained tamponade with silicone oil. Among the remaining 43 patients, 33/34 patients (97.1%) in the non-trauma group and 9/9 patients (100%) in the non-trauma group (P = 0.661) achieved comparable final surgical anatomical success. Additionally the final vision was comparable between the two trauma categories (Snellen equivalent of 20/125 for the non-trauma group and 20/200 for the trauma group, P = 0.331). In multivariable regression, no significant factors related to primary reattachment rate or final vision were identified. Non-penetrating ocular trauma did not emerge as a significant risk factor for recurrent detachment post-surgery. This study supports that PPV outcomes in GRT–RRD patients are unaffected by the ocular trauma association and reports the effectiveness of PPV in managing these patients.
