The analysis of correlative factors of retinal detachment caused by contusion

Objective The correlative factors of contusive retinal detachmentwere evaluated. Methods The location and the types of retinal breaks,the time interval from contusion to recognition of retinal detachment,reattachment rate and, visual aruity results of these 96 cases are re-viewed. Results Of the retinal breaks recognized giant tear and dialpsisat the ora serrata were oberved in 17 eyes,of which 12 were situated atthe lower temporal quadrant. Fifty-three eyes had irregular breaks Eightpatients had retinal breaks or retinal detachment diagnosed within oneweek of contusion abd 39 within six weeks. Surgical treatment successful-ly restored or maintained retinal apposition in 93 .3% of the eyes.Thirtyfive eyes recovered visual aculty of 0. 1 or better,of which 30 eyes withinsix weeks. Conclusion Visual prognosis was good when retinal break ordetachment were diagnosed withen six weeks of contusion. However,thosepatients who escaped initial retinal examination and were lost to follow -uphad a less favorable visual outcome.
