Pars Plana Vitrectomy for Idiopathic Impending Macular Hole-A Case Report
經扁平部玻璃體切除治療impending黃斑部裂孔－病例報告
摘要
特異性或老年性黃斑部裂孔是造成老年人中心視力下降之常見原因。臨床上，黃斑部裂孔之發展可分為四期。其致病原因可能與玻璃體cortex對黃斑之平行性牽引有關。我們報告一例57歲女性病人主訴右眼視力模糊，視物扭曲有一週之久。病人左眼兩年前已被診斷有特異性黃斑部圓孔。生化顯微鏡檢查發現病人右眼有第一期之impending黃斑部裂孔。病人接受經扁平部玻璃體切除手術，移除後玻璃體cortex,，病人視力術前之20/100進步到術後六個月之20/25。此臨床經驗顯示，當另一眼已有全層之黃斑部圓孔時，吾人可以利用手術治療impending黃斑部裂孔。

Idiopathic or senile macular hole is a common cause for reduced central vision in old aged patients. Clinically, the development of macular hole can be divided into four stages. The pathogenesis may be related to the tangential traction of the cortical vitreous on the macula. We presented a 57-year-old female who complained of blurred vision, metamorphopsia in her right eye. She had idiopathic macular hole in her left eye for two years. Biomicroscopy examination revealed stage 1 impending hole in her right eye. Pars plana vitrectomy was carried out to remove the posterior hyaloid membrane. The visual acuity increased from 20/100 preoperatively to 20/25 after six months of follow-up. Surgical intervention may be indicated in treating the impending hole when fellow eye had full-thickness hole to prevent bilateral loss of central vision.
