AIM:To investigate the proportion of different types of cataract,distribution of genders,ages,nationalities and economic standard,as well as the changes of hospitalized patients with cataract,to provide new epidemiological data for prevention and cure and investigation of cataract.·METHODS:A total of 984 cases in our Department of Ophthalmology from January 2003 to December 2007 were studied.Based on the classification of discharge diagnosis,the structure of ages,distribution of genders and natio-nalities,and economic standard in groups of patients were analyzed,as well as the constitutive proportions of each kind of cataract.The data were then compared between two periods (year 2003 and year 2007).·RESULTS:Senile cataract was also the main part in our hospital.During the period 2003,senile cataract constitu-ted 82.10% of all cataract,while it changed to 53.76% during 2007,complicated cataract constituted 3.08% in 2003,27.07% in 2007 (P<0.05).From 2003 to 2007,constituent of each year in these 5 periods increased slowly,but compared with 2003,constituent of 2007 had increased 1.64 times (P<0.05).In these 984 cases,male patients exceeded female patients,male patients 553 cases,average age was 60.09,female patients 431 cases,average age was 62.22.In these 5 years,cataract patients were primarily Han nationality and Uighur nationality,and Han nationality exceeded Uighur nationality.With the division of north Xinjiang and south Xinjiang,the patients of north Xinjiang exceeded south Xinjiang,and urban patients exceeded village patients.·CONCLUSION:Compared with the constitutive portions of hospitalized patients with cataract in other hospitals,the results were not all the same in our Department of Ophthalmology.Senile cataract was also the main part.
