Purpose. To evaluate long-term results of surgery for proliferative diabetic retinopathy using contrast-enhanced viscodissection. Material and methods.The study involved 30 patients with type 1 diabetes mellitus (DM) and PDR with traction retinal detachment (TRD). All patients were divided into two groups. In the main group, viscodissection with contrast was performed; in the control group, segmentation and membrane removal were performed using a vitreotome and endovitreal forceps. The observation period was 12 months. Results. During dynamic observation, all patients showed a positive dynamics of morphofunctional parameters. In patients of the control group, in the vast majority of cases, it was necessary to resort to tamponade with silicone oil (60%) or gasair mixture (33%), while in the main group, the main postoperative media were sterile BSS solution (73%) and gas-air mixture (27%). 60% of patients in the control group required a reoperation to remove silicone oil. In patients of the control group in the late postoperative period, IOP values were significantly higher (main group 14.3 ± 1.1; control group 18.7 ± 1.5; p < 0.05), and late postoperative vitreous hemorrhage developed more often (2.3 ± 0.5 in the main group, 4.1 ± 0.6 in the control group; p < 0.05). Conclusion. In the long-term follow-up, the use of this method reduces the need for repeated endovitreal intervention, reduces the risk of developing late postoperative vitreous hemorrhage, and has a positive effect on IOP by reducing the need for endotamponade with silicone oil. Keywords: diabetes mellitus, proliferative diabetic retinopathy, vitreoretinal surgery, contrastenhanced viscodissection
目的。目的:评价增殖性糖尿病视网膜病变的长期手术效果。材料和方法。本研究纳入30例1型糖尿病(DM)合并PDR合并牵引性视网膜脱离(TRD)患者。所有患者分为两组。主组采用黏液解剖加造影剂;在对照组中,使用玻璃体切割机和玻璃体钳进行分割和膜去除。观察期为12个月。结果。在动态观察中,所有患者形态功能参数动态均呈阳性。在对照组患者中,绝大多数病例需要使用硅油(60%)或气体混合物(33%)进行填塞,而在主组中,主要的术后介质是无菌BSS溶液(73%)和气体混合物(27%)。对照组60%的患者需要再次手术去除硅油。对照组患者术后后期IOP值明显高于对照组(主组14.3±1.1;对照组18.7±1.5;P < 0.05),且术后晚期玻璃体出血发生率较高(主组2.3±0.5,对照组4.1±0.6;P < 0.05)。结论。在长期随访中,使用该方法减少了重复玻璃体干预的需要,降低了术后晚期玻璃体出血的发生风险,减少了硅油内填塞对IOP的需要,对IOP有积极的影响。关键词:糖尿病;增生性糖尿病视网膜病变;玻璃体视网膜手术

Introduction. Recurrent strabismus is a common issue after operations because of heterotrophy. Many scientific works have examined clinical parameters that may predispose to relapse of esotropia after surgery, including poor sensory status, high ratio of accommodative convergence to accommodation, uncorrected farsightedness or combination of these factors. Purpose. To evaluate the effectiveness of prismatic correction of recurrent esotropia in patients after the first stage of surgical treatment. Material and methods. The study group included 24 patients. They were divided into two groups in depends on the postoperative functional treatment. 1st group consisted of 12 patients with partially accommodative esotropia aged 5 to 8 years (6,48 ± 1,12 years) with average hypermetropic refraction +3,10 ± 0,54 diopters. This group of patients was assigned prismatic correction after a relapse of esotropia. 2st group consisted of 12 patients with partially accommodative esotropia aged 5 to 8 years (6,22 ± 1,29 years) with average hypermetropic refraction +3,13 ± 0,61 diopters. This group of patients was assigned orthoptic treatment after a relapse of esotropia. Results. Prismatic correction contributed to recovery binocular vision at 75 % of patients with recurrent esotropia ≤ 20 PD, in the comparison group (orthoptic treatment) – at 50 %. Moreover, the number of patients with stereopsis in the group «EFP» after the treatment was higher than in the group «Synoptophore» (p < 0,05). Conclusion. Prismatic correction ensures optimal motor status while maintaining sufficient sensory balance in most patients with recurrent esotropia after performing recession rectus medialis in combination with median duplication m. rectus lateralis. Keywords: Recurrent strabismus, binocular vision, elastic Frensel prism
介绍。术后复发性斜视是手术后常见的问题。许多科学工作已经检查了可能易导致内斜视术后复发的临床参数,包括感觉状态差、调节收敛比高、未矫正远视或这些因素的组合。目的。目的评价复发性内斜视一期手术后棱镜矫正的效果。材料和方法。研究组包括24例患者。根据术后功能治疗情况分为两组。第一组12例患者为部分调节性内斜视,年龄5 ~ 8岁(6,48±1,12岁),平均远视屈光度+3,10±0,54屈光度。本组患者在内斜视复发后接受棱柱矫正。第2组12例患者为部分调节性内斜视,年龄5 ~ 8岁(6,22±1,29岁),平均远视屈光度+3,13±0,61。本组患者在内斜视复发后接受矫正治疗。结果。在复发性内斜视≤20pd的患者中,75%的棱镜矫正有助于双目视力的恢复,而在对照组(矫正治疗)中,这一比例为50%。此外,治疗后“EFP”组出现立体视的患者数量高于“synoptophoore”组(p < 0.05)。结论。棱柱形矫正可确保大多数复发性内斜视患者在行内侧直肌后退联合正中重复肌外直肌手术后的最佳运动状态,同时保持足够的感觉平衡。关键词:复发性斜视,双眼视力,弹性Frensel棱镜

To date, the number of endovitreal interventions (EVI) is steadily increasing every year, and with them the understanding of the most common negative effects of these manipulations on some structures of the eye. One of the most common complications of EVI is the formation of cataracts. The aim of the study was to identify morphometric changes in the lens and the depth of the anterior chamber of the eye after EVI. The 1st study group consisted of patients after vitrectomy with tamponade of the vitreal cavity with sterile BSS solution, the 2nd group included patients after intravitreal injections of anti-VEGF drugs. We have not recorded significantly significant changes in the studied parameters, which allowed us to conclude that there is no significant effect of some types of EVI on the rate of cataractogenesis. Keywords: cataract, vitrectomy, lens

Purpose. To study biomarkers of ischemia of the organ of vision in patients with acute disorders of the arterial circulation of the retina and optic nerve. Material and methods. We observed 38 patients (38 eyes). The patients were divided into two groups, the first group consisted of 26 patients (26 eyes) with acute circulatory disorders of the optic nerve (anterior ischemic neuropathy), the second group consisted of 12 patients (12 eyes) with acute circulatory disorders of the retina (occlusion of the central artery retina and its branches). The control group consisted of 12 practically healthy individuals. Results. In a biochemical study in patients with anterior ischemic neuropathy (1st group), the level of NSE in the lacrimal fluid was increased compared to the control group and averaged 32.3 ± 0.85 ng/ml, although in the blood serum it remained within the normal range , which reflects the beginning of destructive processes in the nervous tissue. In patients with acute circulatory disorders of the retina (2nd group), the content of NSE in the lacrimal fluid was increased by 1.7 times compared with the control group. Conclusion. The NSE study can be used in a comprehensive examination of patients with acute circulatory disorders of the optic disc and retina as an additional marker of the neurodegenerative process. Since data from traditional methods of research do not always show the degree of damage to the visual pathways, the study of the level of NSE helps to make assumptions about the severity of the disease and predict the outcome.

目的。目的:研究急性视网膜和视神经动脉循环障碍患者视觉器官缺血的生物标志物。材料和方法。我们观察了38例患者(38只眼)。将患者分为两组,第一组26例(26眼)视神经急性循环障碍(前缺血性神经病变),第二组12例(12眼)视网膜急性循环障碍(视网膜中央动脉及其分支闭塞)。对照组由12名实际健康的人组成。结果。在前路缺血性神经病变患者(第一组)的生化研究中,泪液中NSE的水平比对照组增加,平均为32.3±0.85 ng/ml,尽管血清中NSE仍在正常范围内,这反映了神经组织破坏过程的开始。急性视网膜循环障碍患者(第二组)泪液中NSE含量较对照组增加1.7倍。结论。NSE研究可用于视盘和视网膜急性循环系统疾病患者的综合检查,作为神经退行性过程的附加标志。由于传统研究方法的数据并不总是显示视觉通路的损害程度,因此对NSE水平的研究有助于对疾病的严重程度做出假设并预测结果。关键词:视觉器官缺血,闭塞,前部缺血性神经病,视网膜中央动脉,诊断,NSE蛋白

The term «glaucoma» unites a large group of eye diseases of various origins with a progradient, chronic course. The aim of this study was to study the neuroprotective effect of Cytoflavin in patients with POAG with normalized IOP based on the clinical and functional parameters of the organ of vision. Material and methods. The study involved 60 patients diagnosed with primary open-angle glaucoma (POAG) stage I, II and III. All patients were divided into 2 groups depending on the treatment received. Results. Cytoflavin has a pronounced neuroprotective effect in POAG, effectively protecting the nervous tissue and slowing down apoptosis. In addition to improving the clinical and functional indicators of the organ of vision, we noted an improvement in overall well-being, attention and overall performance in all patients. Conclusions. Analysis of the obtained results indicates a rather high clinical efficacy of Cytoflavin in the conservative treatment of patients with POAG with compensated IOP and can be recommended as a background neuroprotective therapy. Keywords: primary open-angle glaucoma, neuroprotective treatment, Cytoflavin, visual functions, glaucoma process

Purpose. To study the effectiveness and features of interval courses of treatment for acquired myopia in school conditions using the device «Visotronic Mini». Material and methods. 25 children (50 eyes) were followed up, their average age was 11.16 ± 1.1 years. Among them were 12 boys and 13 girls who underwent 4 courses of optical kinesiotherapy using the device «Visotronic Mini». The interval between treatment courses averaged 6 months. The ophthalmological examination included questionnaires, visometry, ophthalmoscopy, skiascopy, determination of subjective refraction, the margin of relative accommodation (MRA) by the Avetisov method, and the study of binocular stability of visual perception (SVP) to hyperopic retinal defocus (HRD). Results. Interval courses of treatment contributed to the improvement of visual acuity by an average of 0.09 from 0.61 ± 0.25 to 0.7 ± 0.28 (P < 0.001) and to the reduction of refraction by an average of (–) 0.18 dptr from (–) 0.87 ± 0.56 dptr to (–) 0.69 ± 0.65 dptr (P < 0.001). MRA increased by an average of 2.84 dptr from 5.36 ± 2.28 dptr to 8.2 ± 2.18 dptr (P < 0.01). The total visual resolution increased by 254 % in the far-vision mode and by 168 % in the close-vision mode. At the same time, the proportionality coefficient decreased from 1.42 to 1.18. Conclusion. Four courses of optical kinesiotherapy using the device «Visotronic Mini» in school conditions significantly increased the efficiency of the accommodation and vergence apparatus of the eye. A marked decrease in the proportionality coefficient against the background of high functional characteristic sindicates a significant steady improvement in the elastic properties of the sclera and the adaptive resource of the eye as a whole.

Interval courses of treatment contributed to the improvement of visual acuity by an average of 0.09 from 0.61 ± 0.25 to 0.7 ± 0.28 (P < 0.001) and to the reduction of refraction by an average of (–) 0.18 dptr from (–) 0.87 ± 0.56 dptr to (–) 0.69 ± 0.65 dptr (P < 0.001). MRA increased by an average of 2.84 dptr from 5.36 ± 2.28 dptr to 8.2 ± 2.18 dptr (P < 0.01). The total visual resolution increased by 254 % in the far-vision mode and by 168 % in the close-vision mode. At the same time, the proportionality coefficient decreased from 1.42 to 1.18. Conclusion. Four courses of optical kinesiotherapy using the device «Visotronic Mini» in school conditions significantly increased the efficiency of the accommodation and vergence apparatus of the eye. A marked decrease in the proportionality coefficient against the background of high functional characteristic sindicates a significant steady improvement in the elastic properties of the sclera and the adaptive resource of the eye as a whole.

Purpose. Evaluation of the effectiveness of multi-staged plastic and reconstructive rehabilitation of the patient with a large lower eyelid defect after the excision of basal cell carcinoma. Material and methods. The patient L., 75 years old, was treated with postoperative coloboma of the lower eyelid, lagophthalmos of the right eye after removal of the eyelid basal cell carcinoma, applied to the S.N. Fyodorov Eye Microsurgery Federal State Institution in Moscow. She underwent a multi-stage reconstructive plastic treatment in order to restore the anatomy and function of the lower eyelid, eliminate the cosmetic defect. Results and discussion. As a result of the first surgical stage, we were able to restore the skin defect using a free skin flap from the upper eyelid of the left eye. The second stage of treatment allowed us to restore the function of the lower eyelid by eliminating the artificial ankyloblepharone created earlier. The consequence of performing the following stages of surgery was the filling of the lack of the mucous membrane of the lower eyelid, the creation of the correct ratio and position of the cutaneous and conjunctival layers of the eyelid, the elimination of lagophthalmos and the restoration of anatomical and functional characteristics of the eyelid. Conclusion. As a result of multi-stage surgical treatment, the anatomical and functional integrity of the lower eyelid was achieved, prevented the loss of visual functions, achieved a satisfactory cosmetic effect, and also improved the patient's quality of life. Keywords: basal cell carcinoma, lower eyelid, staged plastic and reconstructive surgery

The retinopathy of prematurity (ROP) is a vasoproliferative disease causing visual impairment. Perpose. To investigate the pathogenic features of ROP. Material and methods. 1254 patients (2508 eyes), operated patients 163 (326 eyes), were included in the study; blood tests were taken from 192 patients (384 eyes). Results. Patients with lower weight, advanced stage of ROP showed greater decline in hemoglobin, lactate and thrombin time in comparison to the babies at risk; T-regulators, such as CD4+CD25highFoxp3+CD127low, correlated with gestational age and the stage of ROP; their level was increased or remained within normal range in aggressive posterior disease (AP-ROP). Serum levels of VEGFA165 and VEGFA165R1 in ROP surpassed those in babieswith congenital cataracts (p < 0.01). 19 pro-angiogenic genes (VEZF1, LTF, CSF1R, EGR1, FGF1, PTN, IFITM, HSP90AB1, HSP90B1, PRDX1, JMJD, ACTA2, XBP1, CCNG1, S100A10, IRS2, UPP1, MGP, OLFML3) and 19 antiangiogenic genes (RHBDF1, CTNNA1, F11R, PSEN2, RHBDF1, PLG, COL18A1, VHL1, EIF4A1, EIFH4, ANKRD23, MIR-16, RAB6B, TSP1, RACK1, NR2E3, TKT, VLDLR, IGFBP4) were detected. Multisensor stripping voltammetry in serum of full-term and premature babieswith ROP demonstrated significant shift of current peak height after injection of Hg (p < 0,01), Cd and Pb (p < 0,05). Conclusion. Premature patients with early stages of ROP have distinctive features of their homeostasis.

Purpose. To conduct a qualitative and quantitative evaluation of the subjective components of the CVS. Material and methods. 346 people participated in the study, who are students of various higher and secondary educational institutions in Russia, whose average age was 20.6 ± 0.1 years. With the help of a multidimensional author's questionnaire, such groups of CVS symptoms as conjunctival, accommodative, visual-motor, neuroreceptor and neuropsychiatric, as well as the frequency and duration of use of devices were evaluated. Results. The average experience of using digital devices among students was 10.6 ± 0.2 years, the frequency of using «I live with a computer / smartphone» turned out to be the most popular, and the most common manifestations of CVS in each group were complaints of dryness, difficulty focusing at a long distance, blurred vision during visual work, sleep disturbance and eye pain. Conclusion. A preliminary analysis of the results of a multidimensional online questionnaire on the qualitative and quantitative analysis of the subjective components of CVS among students showed the need to take into account and further study such symptoms as neuroreceptor and psychoneurological, which could expand the possibilities of diagnosing CVS and help in the subsequent assessment of clinical complaints of CVS in people using digital devices.

In the modern world, there is an increase in the severity of computer vision syndrome (CVS) when using digital devices. Despite numerous studies of ophthalmic symptoms of CVS, neuro-ophthalmic manifestations remain poorly understood. Evaluation of spatial contrast sensitivity (SCS) indicators can be relevant and informative in identifying functional changes in the visual system when using devices. A pilot study was conducted with the participation of 15 healthy people. The subjects were assessed the SCS in the process of habitual activity in a personal device, which was considered a visual load using the author's program «Visocontrastometry» after 15 minutes, 30 minutes, 45 minutes of use. The results were analyzed using descriptive statistics, and the nonparametric Mann – Whitney test was used to test for significance. According to the data obtained, in all time intervals, there is a decrease in SCS at the experimental stage compared with the control indicators of SCS. A statistically significant difference is observed 15 minutes after the visual load at a spatial frequency of 1.0 cycle/deg in the blue color range (p ≤ 0.05). The method for assessing the SCS has shown its adequacy for studying the neuro-ophthalmological aspects of CVS. Keywords: сomputer vision syndrome, contrast sensitivity, device
在现代世界,当使用数字设备时,计算机视觉综合征(CVS)的严重程度有所增加。尽管对CVS的眼部症状进行了大量研究,但对神经眼部表现的了解仍然很少。空间对比敏感度(SCS)指标的评估可以在使用设备时识别视觉系统的功能变化方面提供相关和信息。在15名健康人的参与下进行了一项试点研究。受试者在使用15分钟、30分钟和45分钟后,使用作者的程序«Visocontrastometry»评估个人设备习惯性活动过程中的SCS,该设备被认为是视觉负荷。结果采用描述性统计分析,采用非参数Mann - Whitney检验检验显著性。根据获得的数据,在所有时间间隔内,与SCS的对照指标相比,实验阶段的SCS都有所下降。在1.0周期/度的空间频率下,视觉负荷15分钟后,在蓝色范围内观察到具有统计学意义的差异(p≤0.05)。评估SCS的方法已显示其在研究CVS的神经眼科方面的充分性。关键词:计算机视觉综合征,对比敏感度,设备
