title: [Long-term results of pars plana vitrectomy and silicone oil in large retinal tears in children].
abstract: Pars plana vitrectomy (PPV) with implantation of silicone oil (ISO) was performed giant tears (GT) in 24 eyes of 22 children aged 6-15 years. In 15 eyes of 13 children idiopathic GT were involved (71%), in 9 eyes (29%) the GT was preceded by an injury-contusion in 5 eyes and a perforating injury in 4 eyes. The patients were followed up for 24-132 months after operation, on average for 55 months. The final anatomical success with an attached macula and functional success with a visual acuity of 0.02 or better were achieved in 18 eyes (75%). The results did not depend on the size of the GT and were better in post-traumatic than in idiopathic GT. The success of the operation declined from 82% after two years and 79% after 3 years to 45% after 5 and more years. The silicone oil was removed in 13 years (46%). Of those in 4 eyes (31%) the detachment relapsed and in two eyes (15%) the relapse was the cause of the final failure. PPV with ISO was a very effective operation in GT. Proliferative vitreoretinopathy was the main cause of surgical failures and a frequent obstacle for removal of silicone oil from the eye. Dispensarization, prophylactic cryopexy and early diagnosis of GT are the main prerequisites of a better prognosis and results in GT in children.
