Insight Into

Purpose: Recent publications have reported that the deep capillary plexus (DCP) area of the foveal avascular zone (FAZ) is significantly larger in eyes following pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair when compared with controls. To the best of the authors’ knowledge, there have been no publications on the evaluation of the macular microvasculature using optical coherence tomography angiography (OCTA) in post–pneumatic retinopexy (PnR) eyes. Therefore, the purpose of this study was to investigate FAZ-area changes following PnR. Methods: This retrospective cohort included 19 patients with macula-off RRD who underwent PnR repair. Each patient’s fellow eye was used as a control. The FAZ area in the superficial capillary plexus and DCP was investigated with OCTA and the areas were measured by 2 masked graders. Results: Both superficial (PnR: 0.22 [0.16-0.35] vs control: 0.24 [0.18-0.34] mm2; P = .715) and deep (PnR: 0.56 [0.51-0.76] vs control: 0.7 [0.59-0.89] mm2; P = .105) FAZ areas were not significantly different between eyes. Conclusions: Our results suggest that the lack of FAZ-area enlargement after PnR repair may indicate that there is less ischemic damage to the retinal capillary plexus in the fovea when compared with that described in the literature for PPV. The PIVOT trial demonstrated that PnR is associated with superior visual acuity and less metamorphopsia when compared with PPV at 1 year. The results of the current study may provide insight into the potential advantages of PnR. Further studies are needed to elucidate how the macular microvasculature is affected after RRD and to clarify how the FAZ area changes following PnR and PPV.

Rhegmatogenous Retinal Detachment

Актуальность. Несмотря на высокую частоту прилегания сетчатки в результате эндовитреальной хирургии, острота зрения в 60% случаев остается низкой или улучшается незначительно. Цель. Оценка эффективности нейропротектора «Цитофлавин» в улучшении остроты зрения после эндовитреальной хирургии регматогенной отслойки сетчатки. Материал и методы. Основная группа наблюдения представлена 20 пациентами с низким зрительным прогнозом, которые получали препарат «Цитофлавин» в послеоперационном периоде (период тампонады силиконом и после удаления силикона). Контрольная группа наблюдения включала 20 человек с низким зрительным прогнозом, получавших стандартное лечение после операции. Критериями оценки эффективности проводимой терапии явились: МКОЗ, амплитуда прироста (АΔ), показателя микроциркуляции (ПМ, перф. ед.), индекса эффективности микроциркуляции (ИЭМ, отн. ед.) относительно исходных, рассчитанная по формуле. Результаты. Результаты исследования показали, что через 6 мес. после операции у пациентов основной группы по сравнению с контрольной МКОЗ выросла более чем в 2 раза (р<0,05). Также при терапии препаратом «Цитофлавин» отмечена более значимая активация хориоретинального кровотока. АΔ, ПМ и ИЭМ у пациентов основной группы исследования к 6 мес. после операции выросла в 2 раза и более (р<0,05), что подтверждает прямую зависимость зрительных функций от состояния и динамики восстановления хориоретинального кровотока. Выводы. При включении нейропротектора «Цитофлавин» в систему медицинской реабилитации пациентов с низким уровнем зрительного прогноза наблюдается повышение МКОЗ в 2 раза и улучшение циркуляторных показателей хориоретинального кровотока более чем в 2 раза.

Purpose. To study the effectiveness of extrascleral filling (ESF) using endoillumination in the surgical treatment of patients with primary rhegmatogenous retinal detachment (RRD). Material and methods. The material for the study was the data of a comprehensive clinical examination and surgical treatment by ESF method using endoillumination in 17 patients (17 eyes) with RRD. In 7 cases (41%), the macular area was involved in the detachment process. In 5 cases (29.4%), local scleral filling was performed. In the remaining 12 cases (70.6%), the local ESF was supplemented with a circling silicone element. Surgical intervention was supplemented by transscleral drainage of subretinal fluid (SRF) in 10 cases (59%) and pneumatic retinopexy with SF6 gas 50% in 8 cases (48%). Results. In the general group of patients, best corrected visual acuity (BCVA) increased from 0.35 to 0.46. In the subgroup of patients with a detached macular area, the positive dynamics is more pronounced, BCVA increased from 0.1 to 0.28. The progression of proliferative vitreoretinopathy caused the recurrence of retinal detachment in two patients (11.8%). Recurrences were diagnosed after 3 and 5 months, respectively. In both cases, a vitrectomy with tamponade of the vitreous cavity with silicone oil 5000 Cst was performed. The percentage of successful anatomical outcome after the first operation in our study was 82%. The percentage of successful achievement of the final anatomical result was 94%. In two cases, additional injection of SF6 gas into the vitreous cavity was required. Conclusion. This type of surgical treatment is an effective method of surgical treatment of patients with RRD. In our study, the successful anatomical outcome after the first operation was recorded in 82% of patients, which correlates with the data of the authors who also used this method (83–92%). Surgeons who performed surgical treatment using this technique in our study note improved workplace ergonomics when visualizing the fundus using an operating microscope and endoillumination compared with indirect ophthalmoscopy. Other teams of authors came to this conclusion as well. In our study, there were no complications associated with the introduction of a light pipe into the vitreous cavity (iatrogenic crystalline lens injury, endophthalmitis), which indicates the safety of this type of surgical treatment.
