The authors are presenting the SLING TECHNIQUE, utilizing human tissue for the retinal detachment caused by a macular break. In the literature on the surgical technique of the retinal detachment caused by a macular hole, the sling technique of Margherio and Schepens is considered the operation of choice among the modalities currently available. They used the following procedure. The lateral rectus and the inferior oblique muscles are temporaily detached from the globe and the eye is then rotated superonasally. The macular hole is perforated exactly by a fine perforated needle under visual control with a binocular ophthalmoscope. A single diathermy current is then released. A silicone band is placed over the posterior half of the globe in the meridian extending from 12 to 6 o'clock, the middle of the band being over the macula and its end near the insertion of the superior rectus and the inferior rectus muscles respectively. An 8mm. grooved piece of silicone is placed under the band in the macular region. When the buckle is in the conect position and of the desired hight, the suture on the end of the band is tied permanently. Modifying the Margherio and Schepens Procedure, we used minimal cryothermy (-60 degrees C, 20 sec.), amniotic tissue and fascia lata instead of the pentrating diathermy, silicone piece and silicone band respectively. A sufficient adhesive chorioretinitis was caused by the minimal cryothermy and the additional implantation of amniotic tissue over the macular area. We did not attempt to see whether there would be sufficient adhesive chorioretinitis with implantation of amniotic tissue only and without cryothermy. Subretinal fluid was drained in every case, because of the fact that spongiosis chorioideae does not take place easily on the posterior pole due to the histologic charecteristic of the choroid in this region. This technique causes less complications and the resulting improvement in vision is excellent.
