The collected variables consisted of age, date, gender, time of injury, time until repair, mechanism of injury, zone of injury, injury associated vitreous hemorrhage, trauma associated RD, post traumatic RD, aphakia at injury, periocular trauma and OTS in cases of OGI. RESULTS: Totally 102 patients with traumatic OGI with a minimum of 12 mo follow-up and a median age at of 48.6 y(range: 3-104 y) were identified. Final best corrected visual acuity(BCVA) was independent from the time of repair, yet a statistically significant difference was present between the final BCVA and the zone of injury. Severe trauma presenting with an OTS score Ⅰ(P<0.0001) or Ⅱ(P<0.0001) revealed a significantly worse BCVA at last follow up when compared to the cohort with an OTS score >Ⅲ. OGI associated RD was observed in 36/102 patients(35.3%), whereas post traumatic RD(defined as RD following 14 d after OGI) occurred in 37 patients(36.3%). OGI associated RD did not correlate with the OTS and the zone of injury(P=0.193), yet post traumatic RD correlated significantly with zone Ⅲ injuries(P=0.013). CONCLUSION: The study shows a significant association between lower OTS score and zone Ⅲ injury with lower final BCVA and a higher number of surgeries, but only zone Ⅲ could be significantly associated with a higher rate of RD.展开更多

The size of the retinal defect and the amount of proliferative vitreoretinopathy were not exclusion criteria. Patients with tractional retinal detachment due to proliferative ischemic retinopathies were excluded.Results: In the study period, 875 primary retinal and vitreoretinal surgeries were performed on 875 eyes. Among the surgeries, episcleral sponges(42.9%) formed the largest part,followed by pars plana vitrectomies(35.0%) and encircling bands(22.2%). Combining episcleral sponges and encircling bands into an episcleral surgery group revealed that two thirds(65%).of the surgeries were episcleral interventions. In the episcleral sponge group, the retinal re-detachment rate after the first surgery was 13%.Conclusion: In a university department as a primary referral unit for retinal detachments, episcleral retinal surgery can still outnumber vitreoretinal interventions, with retinal re-detachment rates which do not differ markedly from the re-detachment rates reported in randomized trials comparing vitreoretinal surgery with episcleral surgery.展开更多
