Application of triamcinolone acetonide assisted visualization of posterior cortex of vitreous body in vitrectomy

Objective To investigate the effect of triamcinolone acetonide(TA) injection on assisting to remove cortex of vitreous body during vitrectomy. Methods About 108 patients(126 eyes) were taken vitrectomy.After removing vitreous body at the central part,0.5 mL TA suspension was injected into vitreous space.The remaining vitreous body at rear retinal surface was marked.The retinal cortex with TA particles was removed. Results The section and scope of remaining cortex of vitreous body at retinal surface were clearly visible and recognized in vitrectomy with auxiliary TA injection,so it was easy to be removed.The mean visual acuity was 0.293 1±0.123 1 before treatment,which was higher than 0.142 3±0.048 5 before treatment. Conclusion The application of TA injection in vitrectomy helps to identify residues,improves safety of operation,and shortens operating time.
