Objective: To investigate the prevalence of dry eye in the general population inJilin Province, discuss and analyze the relationship between the risk factors associatedwith dry eye and its severity.Methods: Adopt cross-sectional study, cities in Jilin province were identified bycluster sampling from July2014to April2015, and all of the general population in theselected sites were notified by investigators. The survey included subjective symptomsof dry eye and eye examination, subjective symptoms obtained through questionnaires,eye examination including slit lamp examination, tear film break-up time (BUT),fluorescein corneal staining (FCS), Schirmer I test (SIT) and meibomian gland functiontests, using Epi Info software system to establish a database, diagnose and analyze thesurvey data refer to diagnostic criteria, and the results were analyzed and processed bySPSS17.0, the prevalences were compared by X2test between the differentcharacteristics, P <0.05with a statistically significant difference.Results: Total of1151people were surveyed, and1094people complete thequestionnaires and eye examination eventually (318males,776females) with theresponse rate was95.05%.897individuals were diagnosed as dry eye, and theprevalence rate was81.99%(897/1094). Male prevalence rate was71.07%(226/318) andthat of female was86.47%(671/776), higher than males (P <0.001). The age groupswere divided19and below,20-29,30-39,40-49,50-59,60-69,80and over, thenumbers of dry eye patients were1,96,115,152,258,196,79, and the prevalence rateswere11.11%(1/9),71.11%(96/135),78.77%(115/146),83.98%(152/181),86.29%(258/299),85.96%(196/228),82.29%(79/96). The prevalence of dry eye in differentage was statistically significant (P<0.001), and that in different ethnic was notstatistically significant; Among different occupations, retirees and workers had highprevalence, while students relatively lower; Compared with the high level of education,prevalence of dry eye in low education level of the population was higher (P<0.05); The prevalence of dry eye was significantly higher (P<0.05) with diabetes, rheumatoidarthritis, allergic diseases, meibomian gland dysfunction and long-term use of eye drops,blink less, smoking, history of ocular surgery.Conclusion: Dry eye in the general population in Jilin province has a very highprevalence, women were susceptible to dry eye than men, age, diabetes, rheumatoidarthritis, allergic diseases, meibomian gland dysfunction and blink less, long-term use ofeye drops, smoking and eye surgery are important risk factors for dry eye.
