Objective To study the clinical characteristics of ocular hypertension which can easily ex-acerbate to glaucoma, and give help to early diagnosis of this kind of glaucoma.Methods The data of 312 out-patient cases from January 2002 to March 2007, which were divided into two groups of with optic disc hemorrhage and without optic disc hemorrhage, was analyzed retrospectively.Results In 312 cases, optic disc hemorrhage had happened in 42 cases(13.46%),and among them, 12 cases were diagnosed as glaucoma (28.57%),In no optic disc hemorrhage cases(86.54%),33 cases were diagnosed as glaucoma(12.22%),and the difference between two groups has statistic significance(Pearson chi2=7.8711 ,Pr=0.005).With further study,the difference between group with optic disc hemorrhage and group without optic disc hemorrhage has statistic significance(t=-2.2911, P=0.0269), while no difference, among two groups with optic disc hemor-rhage,two groups without optic disc hemorrhage,or two groups which have not been diagnosed as glaucoma, has statistic significance(t=1.8493, P=0.0718; t=0.5915, P=0.5547; t=0.7039, P=0.4821).Conclusion Optic disc hemorrhage is a risk factor for ocular hypertension which can easily evolved to glaucoma,and this status is worsened in higher ocular hypertension case.
