Laser and surgery treatment of retinoschisis

Purpose To find new methods to cure retinoschisis. Methods Observed:130 patients. In1and 2 stages of process there were 80 patients (80 eyes). For these cases we used our method – step‐by‐step progression – beginning laser coagulation around the macula and toward the periphery retina. We used diode laser. Radiation power: 350mW‐850mW, wavelength: 0,83 mm, exposition 0,2 s, spot diameter: 150‐200mm. In 3 stage there were 50 patients (50 eyes), but in 3 stage laser coagulation was used only in 27 cases. In 23 cases we used surgery because these patients had new retina ruptures with traction by vitreous body. Before operation laser coagulation around macula zone and along the vessels. For surgery a segment‐oval silicone sponge imрlants was used. This implant is constructed with unilateral protuberant surface that affords to get sufficient press roller to blockade any schisis holes in eye retina. Application method of segment oval consists: implant lies on sclera on its convex surface and is fixed by several nodulous sutures in projection of retinal ruptures. Implant is not strengthening out in length but is applanated toward retina. It is possible to blockade large gigantic ruptures, dialysis and group of ruptures in retina. We did not drainage intraretinal fluid; repeated laser‐coagulation in 7 days after operation Results 1‐2 stages of retinoschisis after 4 session of laser coagulation we observed complete cysts delimitation outside macular zone. Complete intraretinal fluid resorption was achieved in 2 years. Conclusion Full fluid resorption was observed in 15 patients in 3 stage of retinoschisis after 5 sessions of laser coagulation. In 12 patients of 3 stage we observed complete cysts delimitation outside macular zone. In 23 cases of 3 stage operations ended with good results
