AIM:To investigate the causes,clinical manifestations,treatment,prognosis of ocular contusion with ciliary detachment.METHODS:Twenty-three cases(23 eyes) of ocular contusion with ciliary detachment were retrospectively studied and the causes,clinical manifestations,therapeutic procedual,prognosis and follow-up records were analysed.RESULTS:Impacting with objects was the most common reason for ocular contusion with ciliary detachment which was followed by trauma by the fist and blast.15 eyes were damaged only in anterior segment,the other 8 eyes were injured in both anterior and posterior segment.Before treatment,best corrected visual acuity(BCVA) of 14 eyes was less than 0.1,accounting for 60.9%.However,the visual acuity of 16 eyes(69.6%) acquired BCVA of 0.5 or better after treatment by medicine or surgery.UBM scan displayed that ciliary detachment disappeared in 21 eyes,IOP remained normal in 21 eyes.CONCLUSION:Integrating UBM,by effective and timely treatment,visual acuity can improve and ciliary detachment disappear in most contused eyes.The visual acuity prognosis is usually poor when the posterior segment complications happen after contusion.
