We examined a 44-year-old woman without any known systemic disease with a decreased vision of a month duration in her left eye. She had undergone left uneventful cataract surgery with intraocular lens implantation elsewhere 14 years ago. On examination, her Snellen visual acuity was 1.0 (with the correction of –0.50–0.25 × 120) in the right eye and 0.4 (with the correction of +0.75–2.25 × 115) in the left. There was left hypochromic heterochromia. While the right anterior segment was unremarkable, there were small to medium-sized keratic precipitates, 3+ anterior chamber cells, a posterior chamber intraocular lens with an intact posterior capsule, and a few vitreous cells in the left eye. Fundus autofluorescence imaging revealed peripapillary hyperautofluorescence in the left eye, and fluorescein angiography revealed a marked optic nerve head and perivascular leakage at the posterior pole. The findings were not compatible with Fuchs uveitis, so the full infectious panel was worked out. Serologic investigations yielded the presence of syphilis, and the patient was treated successfully with systemic antibiotics. Our case demonstrates the mimic-king nature of ocular syphilis and the importance of high clinical suspicion when reaching the correct diagnosis.

Inflammatory diseases of the retina and choroid (chorioretinitis), including those of toxoplasmosis etiology usually occur against a background of decrease in immunity. We present two clinical cases of ocular inflammation at different times after the vaccination with Sputnik V. An analysis of the occurrence of ocular pathologic condition after vaccination to prevent coronavirus infection caused by the SARS-CoV-2 virus will help determine the criteria for prophylactic ophthalmological examination of patients before vaccination.

BACKGROUND: Information on retinal capillary perfusion in idiopathic full-thickness macular hole (FTMH) is limited, and there are no data on the possible effect of blood supply to individual areas and layers of the retina on their functional activity. AIM: To study the relationship between vascular perfusion in the superficial and deep capillary plexuses (SCP and DCP) and the bioelectrical activity of the retina in full-thickness macular hole. MATERIALS AND METHODS: Multifocal electroretinography (mfERG), optical coherence tomography (OCT), and OCT-angiography (OCTA) were performed in 18 eyes with FTMH and 10 intact eyes. In the projection of individual hexagons of the mfERG pattern, parameters of bioelectrical activity were compared with structural changes (hole, cystic changes), capillary density in the SCP and DCP. RESULTS: In the FTMH group, the density of capillaries in the superficial capillary plexuses correlated with P1 implicit time in the R2 ring hexagons (R = 0.23, p 0.05), in the hole zone and intraretinal cystic changes (R = 0.21 and R = 0.22, p 0.05), P1 amplitude in the hole zone (R = 0.24, p 0.05). In deep capillary plexuses, the capillary density correlated with N1 implicit time at the fixation point and the hole zone (R = 0.57 and R = 0.19, p 0.05), P1 implicit time at the hole zone (R = 0.2, p 0.05), P1 amplitude in the hexagons of the R2 and R3 rings (R = 0.46 and R = 0.44, p 0.05), more pronounced in the hole zone and cystic changes (R = 0.54 and R = 0.29, p 0.05). CONCLUSIONS: There is a correlation between capillary perfusion in different layers of the retina and its bioelectrical activity in FTMH. A decrease in perfusion in the deep capillary plexus of the macula with a chronic macular hole may be a predictor of a low functional prognosis in the outcome of surgical treatment of FTMH.
背景:关于特发性全层黄斑孔(FTMH)视网膜毛细血管灌注的信息有限，并且没有关于单个区域和视网膜层的血液供应对其功能活动可能影响的数据。目的:研究浅、深毛细血管丛(SCP和DCP)血管灌注与全层黄斑孔视网膜生物电活动的关系。材料与方法:对18只FTMH患者和10只完整眼进行多焦视网膜电图(mfERG)、光学相干断层扫描(OCT)和OCT血管造影(OCTA)检查。在mfERG模式的单个六边形投影中，比较了SCP和DCP的结构变化(孔洞、囊性变化)、毛细血管密度的生物电活性参数。结果:FTMH组浅表毛细血管丛毛细血管密度与R2环六边形P1隐隐时间(R = 0.23, p 0.05)、孔洞区和视网膜内囊变P1隐隐时间(R = 0.21和R = 0.22, p 0.05)、孔洞区P1振幅(R = 0.24, p 0.05)相关。在深部毛细血管丛中，毛细血管密度与注视点和孔区N1隐含时间(R = 0.57和R = 0.19, p 0.05)、孔区P1隐含时间(R = 0.2, p 0.05)、R2和R3环六边形P1振幅(R = 0.46和R = 0.44, p 0.05)相关，在孔区和囊变中更为明显(R = 0.54和R = 0.29, p 0.05)。结论:FTMH大鼠视网膜各层毛细血管灌注与其生物电活性存在相关性。伴有慢性黄斑孔的黄斑深毛细血管丛灌注减少可能预示着FTMH手术治疗结果的低功能预后。

BACKGROUND: Despite the ever-expanding arsenal of IOP-lowering surgeries, trabeculectomy remains the most common procedure amongst them. Therefore, the identification of factors reducing its effectiveness and potentially being able to change the surgical treatment plan is of particular importance. AIM: To identify factors reducing trabeculectomy effectiveness. MATERIALS AND METHODS: The study group consisted of 443 consecutively enrolled patients who were operated in 20162020 in Saint Petersburg City Multidisciplinary Hospital No. 2 for primary open-angle decompensated glaucoma and then observed for 6 to 24 months. Using statistical research methods, factors that significantly affected the impact of the procedure were identified. RESULTS: The main predictors of trabeculectomy failure following the order of decreasing importance of established relations (p) were: loss of effectiveness of the preceding IOP-lowering procedure (р = 0.0001), dry eye syndrome (р = 0.013), number of drop instillations per day (р = 0.041), and excessive preservative load due to unnecessarily aggressive topical glaucoma treatment (р = 0.039). An obvious demonstration of excessive therapy is a simultaneous administration of four IOP-lowering medications. It also causes scarring of the procedure area, especially in patients previously operated for glaucoma. Null preservative load and prostaglandin monotherapy are associated with guaranteed complete success of trabeculectomy. Unlike the intensity of medical glaucoma treatment, its duration does not have such a significant impact on trabeculectomy outcomes (р = 0.270). Close to a significant one is the relationship between poor surgical outcomes and advanced stages of the disease (р = 0.052). CONCLUSIONS: The main factors affecting the effectiveness of trabeculectomy were failure of the previous IOP-lowering surgeries; concomitant dry eye syndrome, arising or being aggravated by unduly intense and prolonged pharmacological effects on the eye surface; as well as delayed appliance for surgical IOP normalization at advanced disease stages.

AIM: To perform the analysis of the age composition of patients with a planned in-patient surgical procedure cataract phacoemulsification. MATERIALS AND METHODS: Three cohorts of patients diagnosed with age-related senile cataract were analyzed for the periods 20002003 (n = 6737), 20072009 (n = 13,015), and 20152017 (n = 1363) on the basis of age at the time of planned surgery in the ophthalmology hospital S.V. Belyaev Kuzbass Clinical Hospital. Persons with a diagnosis of congenital, complicated, traumatic cataract and persons operated as out-patients were excluded from all samples. RESULTS: At the first stage, the average age of patients at the time of surgical treatment of patients diagnosed with senile cataract was calculated. At the second stage, the age of operated patients was analyzed by decades of human life. At the third stage, the assessment of the judgment about the rejuvenation of the age of operated patients with incipient cataract according to professional indications was carried out. CONCLUSIONS: The average age of patients operated on with senile cataract during a fifteen-year period is a stable value in the range of 6668 years. In the dynamics from 2000 to 2017, there was a redistribution of patients with senile cataract within the cohort by age. Rejuvenation of the age composition of persons with cataracts occurred due to an increase in patients aged 5160 years by 2 times and a decrease in patients aged 7180 years by 1.6 times. The proportion of patients undergoing surgical treatment for senile cataract in a hospital setting with visual acuity of 0.1 or less is stable and amounts to 78.487.5 %.

BACKGROUND: The MyoRing implantation into a corneal transplant can significantly compensate for irregular post-keratoplastic astigmatism. However, the cataract that occurs in this category of patients and the lack of information in the literature on its phacoemulsification and the calculation of a toric intraocular lens (tIOL) power in them determines the relevance of our study. AIM: The aim of the study is to conduct a clinical and functional analysis of phacoemulsification in patients after previously performed implantation of a MyoRing into a corneal transplant. MATERIALS AND METHODS: We operated on 21 patients (21 eyes) who had previously undergone the MyoRing implantation into a corneal transplant. According to keratotopography, all patients were diagnosed with a regular form of corneal astigmatism. All patients underwent phacoemulsification with tIOL implantation. When calculating the tIOL power, its diopter value was corrected depending on the average value of the corneal transplant keratometry according to the keratotopogram data. The observation period duration was 6 months. RESULTS: One month after the procedure, there was an increase in uncorrected visual acuity by 0.2 0.9 LogMAR, best corrected visual acuity by 0.3 1.0 LogMAR, the spherical component of refraction up to 0.4 0.44 D, the cylindrical component of refraction up to 0.62 0.18 D, all of which did not change later on. CONCLUSIONS: Phacoemulsification with tIOL implantation, with its power calculated taking into account an additional correction for its diopter value, is an effective, predictable and safe method of treating patients after previously performed MyoRing implantation into a penetrating corneal transplant.
