[Post-traumatic retinal detachment]

A total of 56 patients with retinal detachment which occurred after direct or indirect injury were treated during a seven-year period. The patients were divided into 4 groups. The first group comprised 27 cases (48.3% of the total) in which retinal detachment has been caused by a direct blow. The second group comprised the cases of detachment caused by a blow on the head. There were 7 of these, or 12.5% of the total. There was only one case in the third group, the detachment having resulted from a severe jolt suffered by the patient. This case represented 1.7% of the total. The fourth group consisted of the cases of detachment following cataract extraction. There were 21 of these, or 37.5% of the total. The latent period between the trauma and the occurrence of detachment varied from group to group and case to case.
