AIM: To investigate the distribution characteristics of gelaucoma in selected population on type formation, sex and age distribution so as to provide data for the prevailing disease for the preventive treatment of glaucoma. METHODS: Between March 2008 and August 2008, we carried out a research on glaucoma for those aged 50 and above undergoing ophthalmological checks covering a population of 1743 patients. The areas covered checks on eyesight, slit lamp microscope, peripheral chamber depth, intra-ocular tension and direct ophthalmoscopy check. For those suspected glaucoma patients, further detailed checks on intra-ocular tension, gonioscope, visual field and eyeground were carried out. RESULTS: There were 36 patients confirmed glaucoma sufferers, constituting 2.06% of the population, of which sufferers of primary closed-angle glaucoma, primary open-angle glaucoma and secondary glaucoma constituted respectively 1.55%, 0.40% and 0.11% of the population. The proportion of male glaucoma sufferers was 1.51% and female 2.53%, with female sufferers being distinctly higher than male ones. Sufferers of primary closed-angle glaucoma were markedly higher than those of primary open-angle glaucoma, with various types of glaucoma increasing proportionately with age. CONCLUSION: The proportion of glaucoma sufferers among those aged 50 and above in this population is close to those sampled in past glaucoma surveys; the proportion of sufferers of primary closed-angle glaucoma is higher than those of primary open-angle glaucoma; the proportion of female primary closed-angle glaucoma sufferers is higher than male ones, coinciding with the results of (past) glaucoma related epidemiological surveys.
