An ocular survey was done on 6,153 children in 30 community schools in the Madang Province of Papua New Guinea over a two year period. Trachoma was diagnosed in 19.6% of subjects but was mild and asymptomatic in most. 9.6% of trachoma patients had moderate to severe disease, but only 5.3% required treatment. A significant refractive error was noted in 1.4% of subjects, and colour perception deficiency was found in 4.7% of boys and 0.5% of girls. 1.2% of subjects had other ocular abnormalities most of which were minor. Training paramedical workers and students in screening methods for ocular disease is one of the most important aspects of ocular surveys as many will be posted to remote areas of provinces which cannot be visited by an ophthalmologist or ocular survey teams.
在两年时间里，对巴布亚新几内亚马当省30所社区学校的6153名儿童进行了眼部检查。19.6%的受检者被诊断出患有沙眼，但大多数症状较轻且无症状。9.6%的沙眼患者患有中度至重度疾病，但只有5.3%需要治疗。1.4%的受检者存在明显的屈光不正，4.7%的男孩和0.5%的女孩存在色觉缺陷。1.2%的受检者有其他眼部异常，大多数情况较为轻微。对辅助医务人员和学生进行眼病筛查方法培训是眼部检查最重要的方面之一，因为许多人将被派往眼科医生或眼部检查团队无法到达的省份偏远地区。
