Abstract:

Objective To investigate  the prevalence and clinical characteristics of posner-schlossman syndrome (PSS) in Hebei Eye Hospital. Design Retrospective case series. Participants 286 patients with PSS treated at Hebei Eye Hospital during the years 2011-2016 through hospital information system. Methods Retrospectively analyze the demographic information, including age, gender, incident season, and visiting frequency of all patients with PSS treated at Hebei Eye Hospital during the years 2011-2016 through hospital information system. Main Outcome Messures Age, gender, years of prevalence, season and frequency. Results There were 286 patients and 527 person-times with PSS treated at Hebei Eye Hospital during the years 2011-2016. Of which 166（58.0%），were male, and 120 (42.0%) were female. Majority of them (81.9%) were 20 to 60 years old, while the proportion of patients less than 20y and over 60y were 5.6% and 12.6% respectively. The average first presentation age was 40.1±15.1 years old. There was no significant difference between the male and female patients in their initial visiting age. The raw five-year-prevalence of glaucomatocyclitic crisis was 16.9/100 000 and annual prevalence was 3.4/100 000.  During summer, the attendance frequency of PSS is slightly higher than the other seasons（P=0.006）. There was no significant change in the number of visits from 2012 to 2016, and 72.1% patients with PSS visited hospital less than 2 times per year.
