| Abstract |
|
Tangential vitreoretinal traction around fovea is known to be the principal cause in the pathogenesis of idiopathic macular holes. According to the recent study, the internal limiting membrane(ILM) may provide a scaffold for fibroblast proliferation and contraction, therefore play an important role in the enlargement of macular hole. We removed the ILM during macular hole surgery and assessed the anatomical and functional outcome of the macular hole surgery. Twelve consecutive patients with full-thickness macular hole were enrolled in this study. They were examed for best-corrected vision, fundus photography, fluorescein angiography, Humphrey automated perimetry, focal eletroretinogram, before and after surgery. After surgery, vision was improved in 8 eyes(67%), hole was closed in 10 eyes(83%). Macular thresholds on visual field was increased in 8 eyes and peripheral scotomas developed in 3 eyes postoperatively. The amplitude increased in 7 eyes and the implicit time decreased in 8 eyes on focal electroretinograms postoperatively. Out results suggested that the complete removal of ILM should be attempted to improve vision and to close holes during the full-thickness macular hole surgery. |
