[Management of traumatic threatened retinal detachment]

10 cases of symptomatic retinal tear and discoid edema from perforating injury are reported as traumatic threatened retinal detachments. All 10 patients were fresh cases with clear refractive media, among them were 1 case of retinal discoid edema that led to retinal detachment, subsequently cured by secondary operation, 3 cases of symptomatic retinal tear that were surrounded by photocoagulation, and 6 cases of discoid edema that were encircled by photocoagulation 'dams' to absorb the subretinal fluid for final photocoagulatory closing of the perforation. All these 9 cases were saved from retinal detachment by prophylactic photocoagulation at an early stage.
