糖尿上眼易損視力 港2萬人中招
 

糖尿上眼易損視力 2萬人中招

糖尿病患者易伴隨視力問題,三分一人會有不同程度的糖尿上眼,包括罹患糖尿病黃斑水腫。眼科專科醫生陳偉民指,本港約廿萬人糖尿上眼,當中十萬人屬黃斑水腫,二萬人更因而視力受損。相關黃斑水腫由視網膜微血管受到高血糖破壞導致,當血液中的水分及蛋白質自血管壁滲出,會導致黃斑區水腫,逐漸破壞視覺組織。

陳指出,糖尿上眼是導致30歲群組等工作階層人士失明的首要原因,惟因病徵不明顯,僅有視力模糊、視物變形等,病人往往在視野出現黑影或嚴重視力下降才求診;而患糖尿病達廿年者,糖尿上眼風險更達80%。傳統的激光治療僅能維持視力不再下降,但近年研發的眼內注射藥物Anti-VEGF能阻止血管異常增生並消除水腫,療效更明顯。
