Cataract is the leading cause of world blindness, even though it can be surgically removed. To raise awareness on preventing visual impairment and restoring sight, World Sight Day is observed on 11th of October this year. This map shows the health burden imposed by cataract by region and cataract surgical rate by country.

As depicted by graduated colours, less than 1000 cataract operations per million population within a calendar year was observed in most sub-Saharan African and Southeast Asian countries. In these regions, the percentage of blindness due to cataract, indicated by blue eye symbols, was also among the highest in the world. On the contrary, low proportion of blindness was caused by cataract in developed world, where mortality is low or cataract surgical rate is high. Both mortality and cataract surgical rate could reflect the delivery of healthcare services, which in turn influences the proportion of blindness due to cataract.

Data for the map were obtained from a report published by World Health Organization in 2007.

縱使能夠經手術根除,白內障仍是全球最主要的致盲原因。今年十月十一日是世界視覺日,希望藉此引起大眾關注如何預防視力受損及恢復視力。地圖顯示各地區因白內障帶來的健康負擔及各國的白內障手術率。

依圖中顏色所示,於東南亞及撒哈拉以南的非洲地區中,大部分國家的年均每百萬人計的白內障手術數目均少於一千。藍色眼睛符號顯示這些地區同時擁有較高比例因白內障致盲的眼疾患者。相反,於低死亡率或高白內障手術率的已發展國家中,因白內障以致失明的眼疾患者數目只佔少數。國家的死亡率及白內障手術率均能反映其醫療服務的供應狀況,從而影響眼疾患者因白內障致盲的比例。
