Objective To find out about the characteristics and prognosis of retinal detachment due to ocular contusion.Methods The clinical data of 36 patients(36 eyes)with retinal detachment due to ocular contusion were retrospectively analyzed.Results There were 3 eyes(8．3％)with huge retinal hole(≥90°)，4 eyes(11．1％)oral tear of ora serrata retinae，4 eyes(11．1％)with macular hole，3 eyes(8.3％)with tractive retinal detachment，and 22 eyes(61．2％)with retinal hole(lt;90°)at other positions(including temporal peripheral hole in 9，nasal peripheral hole in 5，and posterior polar hole in 8).Proliferative vitreoretinopathy(PVR)was found in a11 patients withConclusions Retinal detachment due to ocular contusion often go with PVR．The interval from contusion to retinal detachment varies from days to months.Visual prognosis can be good when retinal detachment is diagnosed and treated in time． (Chin J Ocul Fundus Dis，2004，20：1-66)
