PURPOSE
To evaluate the influence of myopia on the progression of normal tension glaucoma. METHODS: A retrospective study of 72 patients with normal tension glaucoma who were treated from 1984. Subjects were divided into 4 groups which are myopic group (D<-1), moderate myopic group (D<-3), severe myopic group (D<-6) and non-myopic group (D>-1). The change of MD (Mean deviation) and CPSD (corrected pattern standard deviation) of non-myopic group were compared to other myopic groups. In addition, we corrected each analysis in commensurate with age, basal IOP, post treated IOP, existence of hypertension and diabetes mellitus in order to preclude the possibility which these factors would influence to the progression. RESULTS: There was no statistically significant difference between non-myopic group and each myopic groups in MD and CPSD changes against refraction. Moreover, with the correction of other factors, there was no statistically significant difference (Mixed method, P>0.1). CONCLUSIONS: Myopia did not affect the progression of normal tension glaucoma once treated. |
