[Forensic medical assessment in post-trauma retinal detachment].
OBJECTIVE
To analyze risk factors associated with post-traumatic retinal detachment and to identify the cause-effect relationship between retinal detachment and blunt ocular trauma in forensic medical assessment.


METHODS
112 cases of forensic medical examination on post -traumatic retinal detachment were retrospectively analyzed.


RESULTS
A variety of retinal abnormalities were found in these cases, including tearing of the ora serrata retinae (4.28%), macular perforation (12.50%), small (<90 degrees) nonmacular retinal perforation (56.25%), larger (>90 degrees) retinal perforation (5.00%), and tractive retinal detachment without perforation (11.6%). Proliferative vitreoretinopathy (PVR) was found in 45 eyes examined. In most cases, retinal detachment occurred between 1 week to 2 months after blunt ocular trauma (61.60%), with 83.93% accompanied with severe myopia (>-3.00D) and 52.67% accompanied with vitreous floaters. Of all cases, 41.07% were directly and 52.68% were indirectly resulted from blunt ocular trauma, and the rest (6.25%) showed no association with blunt ocular trauma. CONCLUSION Many risk factors may result in retinal detachment including blunt ocular trauma and other causes. Accurate assessment of the relationship between blunt ocular trauma and retinal detachment is an important part of forensic examination.
