Preliminary results of modifed cryogenic scleroplasty

Summary:

Purpose: to assess preliminary results of modifed cryogenic scleroplasty efcacy in patients with progressing myopia. Material and Methods. Modifed cryogenic scleroplasty was developed by us in order to decrease the risk of deformation, torsion and displacement of scleroplastic material during its implantation. 38 children (72 eyes) aged 7–17 years with diagnosis of acquired progressing medium and high myopia with documented annual gradient of progressing more than 1 D were operated. 35 children (64 eyes) were the control group. They underwent standard scleroplasty by Pivovarov — Pristavko method. Results. No complications and adverse reactions to the transplantation material were observed during modifed cryogenic scleroplasty. Due to exposition in liquid nitrogen solution transplant keeps form and is not deformed during immersion and its partial location under the muscle. Stabilizing efect of the studied method (according to clinical refraction and axial length) is comparable to other types of scleroplasty. Conclusion. The developed technology of surgical treatment of progressing myopia is characterized by technological simplicity, convenience in material implantation, exclusion of transplant deformation and torsion on episclera surface, high stabilizing efect during the frst year after the surgery.

Summary:

Purpose: to evaluate the efectiveness of surgical treatment of rhegmatogenous retinal detachment with central, paracentral and peripheral tears using autologous conditioned platelet rich plasma (ACP), without endolaser photoco- agulation and silicone oil tamponade. Material and Methods. The operative technique consists of carrying out 25 & 27 Ga vitrectomy, removing the posterior hyaloid membrane, the inner limiting membrane in the presence of a macular hole, pneumoretinopexy. ACP, devoid of leukocytes and containing 1.5–3 times more platelets that found in whole blood is then instilled into the central, paracentral and / or peripheral retinal tears in 2–3 layers including retina around the tear. 59 patients with visual acuity from the correct visual projection to 0.9 were treated. Results. The retina was reattached in 96.6 % of patients and the retinal tears were blocked; two patients with multiple peripheral tears underwent operation. Over a 1–12 months follow up period, 4 recurrent retinal detachments were recorded, which also required repeat surgery. In 93.2 % of patients complete retinal reattachment and blocking of the retinal defect was achieved. The visual acuity of the operated patients was 0.03–0.9. Conclusion. 25 & 27 Ga vitrectomy of retinal detachment with central, paracentral and peripheral tears and blocking of retinal defects with ACP without endolaser photocoagulation of the retina and silicone tamponade is a method that enables total retinal reattachment and better functioning of the operated eye to be achieved in most cases.
