Sung H, et al. – An investigation was carried out of the relationship between socioeconomic status and the visual impairments caused by primary glaucoma in Korea. A higher association existed between both entities in glaucoma patients without pre–existing glaucoma history before visual impairment. Since glaucoma had not been diagnosed and recognized yet, the variations were probably derived from the disparities of the awareness of glaucoma. The link between socioeconomic factors and the visual impairments by glaucoma were brought to the lime light. It raised public health needs over the significance of glaucoma awareness and eye screening for glaucoma, especially for low socioeconomic status.
