[Retinal detachment after perforating eye injuries. IV. Anatomic and functional results of cryosurgical procedures].

In the course of ten years the authors operated 69 patients with detachment of the retina (DR) after perforating eye injuries, using cryosurgical methods with silicone episcleral implants. In 37 patients DR developed after simple perforation (group A) and in 32 patients after perforation of the eye with an intraocular foreign body (group B). In all patients the perforation affected the vitreous space. From the total number of patients anatomical apposition of the retina was achieved in 62.3%. A significant difference is the poorer anatomical result of the operation in the group with simple perforations without a foreign body 54.0%, as compared with the group after perforation with a foreign body, 71.9%. The anatomical results were evaluated with regard to the period of DR, aphakia, the characteristic of the retinal defect, the type of LR and the extent of the operation. From the total number of successfully operated patients we recorded the same or better vision in 44.2% and in 51.2% poorer vision, as compared with that after the perforating injury of the eye. Deterioration was caused by the duration of DR, detachment of the macular region, an extensive operation and complications.
