mall Ciliary Body Tumor: Ultraound Biomicrocopic Aement and Follow-up of 42 Patient Original Reearch Article

Purpoe Detecting and following mall tumor of the ciliary body i a particular challenge becaue of their location. Recently high-frequency ultraound biomicrocopy (UBM) ha been ued to ait in thi tak. The aim of thi tudy wa to evaluate thi ubet of mall ciliary body tumor through the ue of UBM. Deign Retropective, noncomparative cae erie. Method Forty-two patient with mall ciliary body tumor (le than 4 mm) from our intitution were included in the tudy with a median follow-up of 4.3 year. UBM wa ued to ae tumor characteritic including height, location, and internal and external feature. The data were collected longitudinally, and tatitical analyi wa performed. Reult Median initial tumor height wa 2.05 mm (range 1.1 to 3.8 mm) a meaured by UBM. By 5 year after diagnoi, five tumor (12%) exhibited growth. The overall mean growth rate wa 0.026 mm per year (P = .00007). The mot rapid period of growth wa in the firt year after diagnoi (growth rate 0.128 mm per year), after which the mean tumor ize appeared to tabilize. Concluion UBM i a valuable tool for detecting and following mall ciliary body tumor (le than 4 mm), a thee leion may go undetected by other method. Depite the potential for local extenion into the iri or choroid, few of the tumor in thi tudy exhibited growth, uggeting that many of thee tumor can be managed conervatively. UBM can be ued to ae variou internal tumor feature; however, arriving at a pecific diagnoi without hitologic correlation i difficult.
