Ultrasound biomicroscopy of ciliary body cysts

Objective To report the incidence and sector distribution of iris-ciliary body cysts in normal subjects and to assess association with age using ultrasound biomicroscopy. Methods 400 eyes of 200 normal subjects age from 20 to 67 years were examined with UBM scan. Any primary iris-ciliary body cysts were recorded in the parameters of quantity, location, and quadrant. Results Cysts were found in 82 （41%） of the 200 subjects. The incidence was 64.58% for subjects 20~30 years, which decreased with age （r=-0.683,P0.05）. 468 Cysts were detected, which were found most frequently and in greater numbers in the inferior and temporal sectors. Gender didn’t affect the incidence（χ2=2.87,P0.05）. Conclusion Ultrasound biomicroscopy disclosed a high incidence of ciliary body cysts in normal subjects, which decreased with age.
