BACKGROUND: The «gold standart» for surgical treatment of patients with proliferative diabetic retinopathy (PDR is vitreoretinal surgery. However, the question of the timing of the removal of primary cataract in this category of patients remains open.AIM: To evaluate the efficacy of phacoemulsification of primary cataract by the second stage after vitreoretinal surgery of PDR patientsMETHODS: 67 cases of surgery treatment of patients with PDR and complicated primary cataract were enrolled. This patients were divided into two groups depending on the treatment tactics. In the 1st group patients were subjected to a two–step surgical procedure: vitreoretinal surgery with silicone oil tamponade performed as the 1st step in their treatment; followed by the 2d step, phacoemulsifi tion surgery and silicone oil removal, and the IOL implantation, respectively. In the 2d group phacoemulsifi tion performed simultaneously with vitreoretinal surgery: phacoemulsification, IOL implantation, vitreoretinal surgery with silicone oil tamponade. The second step differed in the removal of silicone oil from the vitreous cavity.RESULTS: Visual functions improved in 88.6% of cases in group 1, and in 68.7% in group 2.CONCLUSIONS: Outcomes of the preliminary studies suggest that it is more viable to perform phacoemulsification surgery sometime later along with silicone oil removal on PDR patients with complicated primary cataract. This sequence of treatment procedure ensures a more gentle approach to the anatomic structures of the eye during the first stage (vitreoretinal surgery) and contributes to the reduction in the number of intraoperative and postoperative complications.

Purpose: To evaluate the anatomic and visual outcomes of a new intraocular mitomycin c (MMC) application technique in the treatment of severe traumatic retinal detachment (RD) with advance proliferative vitreoretinopathy (PVR). Methods: The records of 15 eyes of 14 patients who underwent vitreoretinal surgery and intraoperative MMC application were reviewed retrospectively. Surgical technique: After performing complicated vitreoretinal surgical procedures (Pars plana vitrectomy, PVR membrane stripping, large retinotomy/retinectomies and intraocular foreign body removal if found etc. . .) retina was attached with perfluorocarbon liquid (PFCL) and partial fluid-air exchange. Endolaser was performed. PFCL was removed to the posterior borders of retinochoroidal wounds, breaks or retinectomy sites. The remaining PFCL was enough to cover and prevent MMC contact with the posterior vital structures including optic disc, macula and underlying RPE and major vascular arcades. Ciliary epithelium and other anterior segment structures were protected from MMC contact with the use of air in the rest of the eye. Then, a 10 µg/mL concentrated MMC solution was carefully injected above the PFCL bubble until it covered PVR or potential areas of PVR development and removed after 60 s. Finally, the remaining PFCL was removed and all eyes were filled with silicone oil. The patients were followed at least 6 months after silicone oil removal. Visual and anatomic outcomes were determined during follow-up period. Results: The mean follow-up time was 19.6 ± 6 months (range 12–27 months). About 100% retinal attachment was achieved with one vitreoretinal surgery during the follow-up period. PVR was not detected around the retinal breaks or retinotomy sites in any eye. Limited macular epiretinal membrane was detected in two eyes and subsequently peeled during silicone oil removal. Preoperative visual acuities were hand motions in seven eyes and light perception in eight eyes. Nine of 15 eyes had a visual acuity of ⩾0.1 during the follow-up period. The mean preoperative visual acuity was logMAR 2.16 ± 0.15 and postoperative visual acuity was 0.80 ± 0.50 ( p = 0.001). There were no additional complications related to intraoperative MMC use during follow-up period. Conclusion: Temporary intraocular MMC use in vitreoretinal surgery yielded good anatomic and visual outcomes after the treatment of traumatic RDs with PVR or those with high risk of PVR development. Furthermore, MMC application appeared to prevent further PVR development after vitreoretinal surgery.

Актуальность. Тампонада витреальной полости силиконовым маслом (СМ) или наличие остатков СМ при авитрии являются показаниями к их удалению, которое может быть выполнено различными методиками, нередко после факоэмульсификации катаракты. Цель. Изучить результаты удаления СМ через задний капсулорексис (ЗК) различными методами. 1. Изучить возможность удаления остатков СМ через задний капсулорексис при авитрии. 2. Провести апробацию удаления СМ через ЗК методом эффузии. 3. Провести апробацию удаления СМ через ЗК методом аспирации. Материал и методы. Под наблюдением находилось 18 пациентов, проходивших лечение в СОКБ №1. Результаты. Операции выполнены без осложнений в ближайшем и отдаленном послеоперационном периоде с улучшением зрительных функций. Выводы. 1. Изучены результаты удаления СМ через задний капсулорексис. 2. Удаление остатков СМ через ЗК при авитрии после факоэмульсификации позволяет повысить степень удовлетворенности пациентов результатами хирургического лечения. 3. Проведена апробация удаления СМ через ЗК методом эффузии, что позволяет качественнее удалять СМ, в том числе эмульгированные фрагменты. 4. Проведена апробация удаления СМ через ЗК методом аспирации, что сокращает время операции, позволяет в большем объеме удалять остатки эмульгированного СМ.

Anatomic Success

Purpose The goal of this study was to identify risk factors for redetachment and/or a worse visual outcome after silicone oil removal (SOR) for complicated retinal detachment. Methods The authors retrospectively analyzed 287 consecutive eyes with SOR between January 1999 and December 2003. Results Anatomic success after SOR was achieved in 81% of the eyes. The overall anatomic success at the end of follow-up was 94%. Postoperative ocular hypertension was found in 8% of the eyes, hypotony in 6% of the eyes, and keratopathy in 29% of the eyes. After SOR 43% of the eyes had an improvement in visual acuity of at least two Snellen lines. After multivariate analysis, male sex, the presence of preoperative rubeosis, and proliferative diabetic retinopathy (PDR) were found to be risk factors for recurrent retinal detachment. Male sex, preoperative visual acuity of <0.1 Snellen lines, PDR, the performance of three more operations, any size of retinectomy, and hypotony were found to be associated with a poor visual outcome of Snellen visual acuity <0.1. Conclusions Retinal detachment after SOR in the current unselected series of eyes occurred in approximately 20%, which is comparable to the Silicone Oil Study reports, published approximately 20 years ago. However, preoperative selection was then made, and less than 50% of the silicone oil-filled eyes had SOR. The higher overall anatomic success in the current study may be due to improved vitreoretinal surgical techniques.
