Abstract：
UNASSIGNED: Visual impairment is a global problem. The World Health Organization (WHO) in 2017 estimated that 36 million people were blind and 217 million people had moderate or severe visual impairment. An untreated or undetected eye problem becomes a threat to the general health of the individual, particularly the health of those that lack the basic needs of life. Most blind people live in low-income countries where increasing poverty perpetuates destitution.
UNASSIGNED: This study aimed at determining the prevalence of visual impairment among the destitute in Onitsha metropolis, which would provide a solid database for designing an effective eye care delivery system for them in the state.
UNASSIGNED: This was a cross-sectional study of 168 destitute individuals in Onitsha. The study was carried out between June and July 2011. Destitute clusters were randomly selected, and all of the eligible participants were interviewed. Presenting visual acuity (VA) at 6 m, refraction, and anterior and posterior segment evaluation were done. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 16.
UNASSIGNED: One hundred sixty-eight destitute individuals-consisting of 93 males (55.4%) and 75 females (44.6%)-were studied, and the age range was 11-78 years with a median age of 45 years. One hundred twenty-nine participants (76.8%) did not have any formal education, all were unemployed, and none had any personal assets or property. Fifty-six participants (33.3%) had ocular disorder. The prevalence of blindness was 12.5% and that of visual impairment was 10.2%. The causes of blindness were glaucoma (6, 28.6%), cataract (5, 23.8%), corneal acuity (5, 23.8%), and empty socket from tumor nucleation and trauma (2, 9.5%).
UNASSIGNED: Ocular findings in all eyes of the destitute are similar to that in the eyes of normal individuals. Destitution is an offshoot of health, social, and economic frustration, and therefore requires a comprehensive approach.

摘要：
■视力障碍是一个全球性问题。世界卫生组织（WHO）在2017年估计有3600万人是盲人，2.17亿人患有中度或重度视力障碍。未治疗或未被发现的眼部问题会威胁到个人的整体健康，特别是那些缺乏基本生活需求的人的健康。大多数盲人生活在低收入国家，那里的贫困加剧使贫困长期存在。
■这项研究旨在确定Onitsha大都市的贫困人群中视力障碍的患病率，这将提供一个坚实的数据库，为他们在该州设计一个有效的眼部护理提供系统。
■这是一项对Onitsha的168名贫困人口的横断面研究。该研究于2011年6月至7月进行。随机选择尖锐的簇，所有符合条件的参与者都接受了采访.在6m处呈现视力（VA），折射,并进行前段和后段评估。使用社会科学统计软件包(SPSS)第16版分析数据。
■研究了一百六十八个赤贫个体，其中包括93个男性（55.4％）和75个女性（44.6％），年龄范围为11~78岁,中位年龄为45岁.一百二十九名参与者(百分之七十六点八)没有接受过任何正规教育,都失业了,也没有任何个人资产或财产.56名参与者(33.3%)患有眼部疾病。失明的患病率为12.5％，视力障碍的患病率为10.2％。失明的原因是青光眼（6，28.6%），白内障（5，23.8%），角膜视力（5，23.8%），肿瘤成核和创伤的空窝（2，9.5％）。
■所有赤贫者的眼睛发现与正常人的眼睛相似。生育是健康的分支，社会,和经济挫折，因此需要一个全面的方法。
