Double visualization using triamcinolone acetonide and indocyanine green during vitrectomy in the treatment of idiopathic macular hole

Objective To evaluate the safety and efficacy of double using triamcinolone acetonide (TA) and indocyanine green(ICG) during vitrectomy with internal limiting membrane (ILM) peeling for idiopathic macular hole(IMH).Methods Pars plana vitrectomy with ILM peeling was performed in 26 eyes of 26 patients.TA and ICG were used respectively to identify posterior vitreous cortex and ILM.Finally,16％ C3 F8 was tamponaded.Results Anatomic closure of the macular hole was achieved in 23 patients,withdrawed in 2 cases and failed in 1 patient with small hole near ora serrata who underwent the surgery with silicone oil tamponaded finally.Visual acuity improved in 21 eyes,remained unchanged in 2 eyes,decreased in one eye.Conclusion The injection of TA makes the posterior vitreous cortex visualized clearly in all patients.Upon the injection of ICG,the ILM can be successfully removed in all patients.Double visualization of the posterior vitreous cortex and ILM using TA and ICG during vitrectomy may be safe and effective.
