RESUMO
Metal retinal tacks were used in 18 patients with complicated retinal detachments, such as giant tears (3 cases), severe proliferative vitreoretinopathy (PVR) (7 eyes) and diabetic traction and rhegmatogenous detachment (8 cases). All eyes had undergone vitreous microsurgery, including excision or segmentation of epiretinal membranes, fluid-air (SF6) or silicone oil exchange. Retinal breaks and the cut edges of retinotomies and retinectomies were successfully sealed by metal tacks. Retinal re-attachment was achieved in 9 cases and partial re-attachment in another 5 eyes (follow-up 3-6 months). Retinal tears in diabetic macular detachment associated with extensive epiretinal fibrovascular membranes were also successfully sealed despite persisting traction. Our first experience indicates that the closing of retinal breaks with metal tacks is a major step forward in retinal re-attachment surgery.

Liquid silicone was used in the surgical treatment of 46 eyes with complex retinal detachment. Forty-six eyes have been followed up for at least 6 months. In 27 of these eyes (58.7%) the retina was totally or partially attached at the 6-month follow-up. Visual improvement was found in 20 of the 46 eyes (43.5%). These results are encouraging considering the poor prognosis of the operated eyes. There were few severe complications during an observation time of 6 months. Liquid silicone was found to be a valuable help in the surgical treatment of severe forms of retinal detachment.
