白內障、老花、老年黃斑病變和青光眼的徵狀是否一樣？| 眼科專科醫生黃嘉偉醫生

隨著年紀增長，很多人都會覺得眼矇。其實，眼矇有很多成因，包括白內障、老花、老年黃斑病變及青光眼。除了眼矇，以上問題也有不同徵狀。^1-4

先講解白內障。大部分白內障患者一開始於較暗的地方視力較差，但當調高光度時又會畏光，甚至看見重影或眩光。¹

老花則是看近物不清楚，看遠物反而比較清晰，如長時間用眼可能還會覺得疲勞。²

老年黃斑病變大多影響中央視力，有時甚至覺得影響彎曲或變形。³

相反，青光眼患者的中央視力正常，但周邊視野範圍慢慢收窄，某些特定青光眼類型如急性青光眼，患者甚至會出現眼痛、頭痛等情況。^4,5

要注意，以上問題通常早期病徵不明顯，^1-4當察覺到徵狀，有可能為時已晚。^3,4若年過50，緊記定期接受全面眼科檢查。
