Optometric services in many parts of the world are unavailable with a resultant lack of information on the epidemiology of visual problems in those countries as well.
A retrospective analysis was conducted on the records of 3,281 patients seen on a VOSH mission to Nicaragua.
The mean spherical correction for each eye was a low hyperopic correction. For eyes having an astigmatism the mean cylinder correction was -1.00 and was usually oriented against the rule.
There was a lower incidence of myopia in this population than for many others that have been studied. There was also a need for a presbyopic correction at an earlier age than for Mid-European populations. A very large number of spectacles must be donated in order to get a sufficient supply for a successful VOSH mission.
世界上许多地区无法提供验光服务，因此这些国家也缺乏有关视力问题流行病学的信息。
对在一次视力恢复志愿者组织（VOSH）前往尼加拉瓜的任务中诊治的3281例患者的记录进行回顾性分析。
每只眼睛的平均球镜矫正为低度远视矫正。对于有散光的眼睛，平均柱镜矫正为-1.00，且通常为逆规散光。
该人群近视发病率低于许多其他已研究的人群。与中欧人群相比，该人群也需要在更早的年龄进行老花矫正。为了使视力恢复志愿者组织的任务成功获得足够的眼镜供应，必须捐赠大量眼镜。
