[Liquid silicone in amotio surgery (II). Report on 280 cases - further development of the technic]

Indications, results, modified techniques and complications in 280 cases treated with fluid silicon are reported. In about 80% of the cases intravitreal silicon injection under binoscopic control was performed according to the principles described by J. Scott. In the most difficult cases a vitrectomy was carried out and silicon was used only as an internal tamponade. In certain situations the retina itself was treated. The new techniques developed for that purpose are discussed. The follow-up period was between six months and four years. An anatomic success was achieved in more than 70% of the cases. Causes of late complications with the first 100 patients who underwent surgery are discussed. Removal of silicon after a certain period appears a real possibility in spite of initial complications.
