AIM:To investigate the type of glaucoma,age and gender distribution and compare them with previous data for the prevention and treatment of the disease.METHODS:Totally 577 hospitalized glaucoma patients in West China Hospital from January 2009 to December 2009 were classified by their diagnosis,gender and age to analyze the changing feature of proportion,and compared with the 971 cases from January 1978 to December 1981 and January 2001 to December 2001.RESULTS:During 1978-1981 and 2001-2002,primary glaucoma constituted 81.3% and 81.4% of all kinds of glaucoma,while it changed to 60.2% during 2009.During 1978-1981 and 2001-2002,primary open-angle glaucoma(POAG) constituted 11.3% and 23.9% of primary glaucoma,and the rate increased to 27.4% in 2009.The median age of primary angle closure glaucoma(PACG) was 62.8,which was increased,and the median age of POAG was 48,without obvious changes.Proportion of women increased in POAG patients.During 1978-1981 and 2001-2002,secondary glaucoma constituted 12.7% and 14.1% of all kinds of glaucoma,while it increased to 33.4% during 2009.CONCLUSION:Proportion of POAG in primary glaucoma seems to have risen.Secondary glaucoma increases significantly.
