METHODS:Thirty-six patients of MIOFD with endophthalmitis accorded with Exclusion and inclusion criteria were retrospectively analyzed. A detailed analysis of the patients' natural factors, preoperative examinations, intraoperative endotamponades choice, postoperative complications and therapeutic effects was performed. RESULTS: BSS was used in 4 eyes without obvious retinal damage. There was no postoperative complication and their visual acuity (VA) was improved. Sixteen eyes that had mild retinal damage filled with C3F8 gas. The postoperative VA improved in 10 eyes (62.5%), 4 eyes (25.0%) remained unchanged and 2 eyes (12.5%) decreased. Only 2 cases occurred postoperative retinal detachment in gas group. Another 16 eyes with serious retinal damage were treated with silicone oil. Postoperative VA of 9 eyes (56.3%) improved, 3 eyes (18.8%) remained unchanged and 4 eyes (25.0%) decreased. The silicone oil group had higher incidence of postoperative complications, but the incidence of secondary treatment had no significant different between silicone oil and gas group. CONCLUSION: An appropriate choice of endotamponades in vitrectomy surgery for MIOFB with endophthalmitis is important for prognosis.展开更多

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
