Proportion Analysis Of Glaucoma Inpatients Admitted For Surgeries

Objective: To analyse the proportions of each glaucoma subtype, gender and age of glaucoma inpatients admitted for surgeries.Methods:Data of glaucoma inpatients admitted in the Eye Center of the 2nd Affiliated Hospital, Medical College of Zhejiang University from January 2001 to December 2008 were reviewed and analysed. The proportions of different glaucoma subtypes [acute primary angle-closure glaucoma (aPACG), chronic primary angle-closure glaucoma (cPACG), primary open angle glaucoma (POAG), secondary glaucoma (SG) and congenital glaucoma (CG)], age groups (<40,40-50,50-60,60-70,70-80, and>80 years), and gender of the patients undergone anti-glaucoma surgeries were calculated. The trends of proportions from 2001 to 2008 were also analysed.Results: A total of 1983 glaucoma patients were included for the analysis, of which the proportions of primary glaucoma, SG and CG were 61.82%,31.07% and 7.16%, respectively. The gender ratios (male:female) of PACG, POAG, SG and CG were 1:2.05,2.41:1,1.94:land 1.45:1, respectively. For PACG, the highest proportions of male and female patients were found to have an age of 60-70 years, while for POAG, higher proportion of patients were seen in the age group of 40-50 years for men and 50-60 years for women. There were more POAG patients than PACG patients with an age<40 years, while in patients>40 years PACG were more seen than POAG.Conclusions:Patients of primary glaucoma, especially PACG, were the major glaucoma population admitted for surgeries in aforementioned Eye Center from 2001-2008. Our results suggest that PACG might be important in persons> 40 years, while POAG in persons< 40 years, in terms of glaucoma prophylaxis and treatment.
