    Abstract:

    AIM: To elucidate the trends and characteristics of congenital ectopia lentis (CEL) in southern China. METHODS: CEL patients from China admitted to Zhongshan Ophthalmic Center (ZOC) from January 2006 to December 2015 were recruited in our study. Residence, gender, hospitalization time, age at surgery, and the presence of other ocular abnormalities and system disease were statistically analyzed in different subgroups. RESULTS: Four hundred and thirty-seven hospitalizations (306 in-patients) diagnosed with CEL from a total of 283 308 hospitalizations were identified, which accounted for 0.15% of the total in-patients. Of the identified CEL in-patients, the total ratio of boys to girls was 2.22:1. Based on a subgroup analysis according to age, patients aged 12-18 years old constituted the highest proportion (31.70%) of all hospitalized CEL patients, and those 0-3 year old constituted the lowest proportion (8.82%) of the total number. The number of CEL increased from 18 to 72 and the hospital based prevalence increased from 8.60% to 18.10% from 2006 to 2015, and the average age at surgery decreased from 9 years old in 2006 to 7.6 years old in 2015. CONCLUSION: The results reveal upward trends in both the number of CEL hospitalizations and hospital based prevalence of CEL in this 10-year study period, but a reduction in the age at surgery, which may reflect the increase of public awareness of children’s eye care in China.
