Triamcinolone assistance pars plana vitrectomy and with Indocyanine green staining internal limiting membrane peeling for highly myopic macular hole retinal detachment

Abstract

Objective To compare the outcome of pars plana vitrectomy (PPV) with triamcinolone (TA) assistance and with Indocyanine green (ICG) staining internal limiting membrane (ILM) peeling for the treatment of highly myopic macular hole retinal detachment (MHRD).Methods PPV was performed using 2 different surgical procedures in 43 highly myopic MHRD eyes with moderate long axial lengths (AXL),mild chorioretinal atrophy,and posterior staphyloma:TA-assisted PPV and with ICG staining ILM peeling (group A,24 eyes),Non-TA assisted PPV and without ILM peeling (group B,19 eyes).Anatomic reattachment of the retina,macular hole closure,and best-corrected visual acuity (BCVA) were measured.Results The rates of retinal reattachment and macular hole closure were higher in group A (91.67％ and 58.33％) than that in group B (78.95％ and 26.32 ％) in the first surgery,especially in macular hole closure rate (P =0.036).The rates of retinal reattachment and macular hole closure were 95.83％ and 58.33％ (group A),94.74％ and 36.84％ (group B) in the second surgery,and no differences between them.There were no differences of BCVA in group A than that in group B (P =0.977).Conclusions PPV with TA assistance and ICG staining ILM peeling are effective for the treatment of highly myopic MHRD with moderate long AXL,mild chorioretinal atrophy,and posterior staphyloma.
