Abstract:
Purpose: to assess the inner retinal layer’s changes of the central retina in comparison with bioelectrical activity of macula assessed by MERG and with thickness of photoreceptor retinal layers in patients with retinitis pigmentosa.Patients and methods: 10 patients (20 phakic eyes) with RP were examined. Mean age was 27.0 ± 18.5 years. Mean best corrected visual acuity was 0.38 ± 0.22. The fundus photography electrophysiological studies were performed besides standard ophthalmological examination. Maximal electroretinogram (ERG) or cone-rod response, ERG to 30 Hz flicker and macular ERG were registered with electroretinograph MBN (Russia). Images were acquired using the protocol of scanning Macula radial (12 lines 9 mm long, each radial image is the average out of 50 scans) with settings ultrafine with automatic segmentation of the retina and calculation thickness. Retinal segmentation with the following calculation of different retinal layers was performed on SD-OCT RS-3000 Advance (Nidek, Japan) with obtainment of the map with 6 mm in diameter in accordance with the Early Treatment Diabetic Retinopathy Study (ETDRS).Results. We revealed increased thickness of retinal nerve fiber layer (RNFL), decrease of thickness of ganglion cell layer (GCL) (p < 0,05) and normal (p > 0,05) inner nuclear layer (INL) thickness. These structural changes are associated with the decrease of bioelectric macula’s activity measured by MERG (decrease of α- and β-wave amplitude) and decrease the thickness of photoreceptor layers in all zones according to EDTRS.Conclusion. Increase of thickness RNFL, decrease of GCL’s thickness and normal INL in patients with RP is associated with decrease of thickness of photoreceptor layers in EDTRS zones and decrease of amplitude of MERG.

Abstract:
Uncontrolled administration and prolonged use of antihypertensive drugs with preservatives often leads not only to subjectively poor tolerance of treatment, but also to a deterioration in the results of subsequent surgery, if required. The manifestations of dry eye syndrome and its aggravation as a result of such drops use can lead the patients to refuse therapy and worsening the prognosis. The manifestations of dry syndrome are often detected before any hypotensive therapy begins, since the functions of secretory cells change with age and there is always the influence of adverse environmental factors. It is necessary to examine the condition of the anterior surface of the eye to resolve the issue of the need to prescribe drugs without preservatives for all patients before the appointment of antihypertensive therapy. However, sometimes it is not possible due to lack of time or equipment. Therefore, it is important to study the condition of the anterior eye surface in patients with newly diagnosed glaucoma before and during treatment with nonpreservative forms of antihypertensive drugs in order to determine the necessity of the first prescription of non-preservative forms of antihypertensive drops to further interpolate its results into practical recommendations. This study revealed that drug treatment of patients with newly diagnosed glaucoma with the drug Timolol-POS® β-blocker on a non-preservative basis along with IOP compensation improves both subjective and objective indicators of the condition of the anterior surface of the eye with maximum effect after 3 months of treatment. This conclusion suggests the importance of the primary appointment for such patients with instillation drops on a preservative basis.

Abstract:
Lens material can be detected behind posterior capsule in case of infusion misdirection syndrome development during phacoemulsification. This condition is associated with Wieger ligament damage. There is no accepted management options for this issue. Authors offer original technique of small diameter (2–3 mm) posterior capsulorhexis performed before IOL implantation for evacuation of infusion fluidics and lens material from Berger space. Safety of new technique was evaluated by OCT images analyzing central foveal thickness in 1 day, 3 weeks and 6 weeks after cataract surgery. There were 3 patients groups: I — uneventful phacoemulsification (10 eyes) (control group); II — phacoemulsification with development of infusion misdirection syndrome and lens material behind posterior capsule without performing posterior capsulorhexis (10 eyes); III — phacoemulsification with development of infusion misdirection syndrome performing posterior capsulorhexis for draining Berger space. There was no significant difference in central foveal thickness between patients groups. There was trend of central foveal thickness increase in 3 weeks after surgery in all groups. Central foveal thickness returns to initial values in 6 weeks after surgery in all patients groups. There was no cases of cystoid macular edema in study. In conclusion, small diameter posterior capsulorhexis technique is useful in clinical practice for evacuation of infusion fluidics and lens material from Berger space before IOL implantation.

Abstract:
According to statistical studies in recent decades, there has been an increase of allergic diseases in most countries of the world. Predisposing factors are the deterioration of the environmental situation, the total “chemicalization” of life and the forced use of drugs. Twenty years ago, the World Health Organization called the new century “the century of allergies” and the disease itself as an “epidemic”. As time has shown, these forecasts have come true: from 2001 to 2010, the number of allergic people in the world increased by 20 % and many of these patients suffer from ophthalmic manifestations of the pathology: the eyes are involved in the process in almost every second case. This is due to the fact that the eyes are directly exposed to the environment and a variety of external allergens. The most common disease of an eye-allergic nature is allergic conjunctivitis: approximately 15 % of the total population of economically developed countries suffer from it. Allergic blepharitis, eyelid dermatitis, keratitis, iritis, uveitis, retinitis and optic neuritis are much less common. The following manifestations are typical for allergic conjunctivitis: burning, lacrimation, pruritus, hyperemia of the eyelids and conjunctiva, photophobia. In the case of a transition to a chronic form, pronounced tissue changes are observed. Therefore, timely diagnosis and effective treatment certainly have a positive effect on the quality of life of the patient and the course of the disease. The treatment of patients with allergic conjunctivitis, first of all, consists in the maximum possible restriction of contact with the allergen. During desensitizing therapy, local and general drugs are used. Numerous studies have proven the advantage of targeted and effective antiallergic local therapy compared with systemic exposure. Currently used local ophthalmic antiallergic drugs belonging to various groups. The tactics of their use is determined by the acuity, severity and etiology of the process. When choosing a drug, in some cases, you should focus on the presence of substances that provide a double mechanism of action: a pronounced antihistamine activity in combination with the stabilization properties of mast cells, which has a quick and long therapeutic effect. This study evaluated efficacy of Vizallergol (olopatadin 0.2 %) application in cases of allergic conjunctivitis in 239 patients was evaluated. The medication arrested the symptoms of allergic conjunctivitis in 89 % of patients, at that the mean period of treatment made 10.7 ± 0.3 days. In the treatment of allergic conjunctivitis, the therapeutic efficacy of Vizallergol 0.2 % was comparable to opatanol 0.1 % and was found to be more comfortable for most patients due to the convenience of a single use.

Abstract:
Purpose. Analysis of refractive errors’ frequency in children with retinoblastoma.Patients and Methods. A retrospective study included 57 children with retinoblastoma (31 male and 26 female) who received treatment in 2013–2017. The criteria for patient selection was the presence of mono- or bilateral retinoblastoma, as well as autorefractometry of both eyes before treatment. In all cases, the study was performed with cycloplegia. The parameters studied included gender, age at the time of the initial examination, visual acuity, spherical and cylindrical component of refraction, the axis of the cylinder.Results. Bilateral retinoblastoma was determined in 34 children (59.6 %), the average age of the patients was 18.0 ± 2.6 months. Monolateral retinoblastoma was detected in 23 patients (40.4 %), the average age at the time of check-up was 26.2 ± 3.1 months. In total, anisometropia of more than 2.0 diopters was detected in 14 patients (24.6 %), of which with monolateral RB in 6 patients (26.1 %) and in bilateral patients in 8 (23.5 %). In 26 cases (45.6 %) anisometropia was determined from 1.0 to 2.0 diopters, of which 41.1 % (n = 14) with bilateral lesion and 52.1 % (n = 12) with monolateral. The frequency of hyperopia over 3.0 diopters in the total cohort was 25.2 %, myopia 3.3 %. Significant differences (p = 0.025) were obtained by comparing the frequency of astigmatism determination of more than 1.0 D (39.6 % in the total cohort versus 13.0 % for healthy eyes). When analyzing the frequency of ametropia depending on age, a trend was observed (0.05 < p < 0.1) to reduce the frequency of hypermetropia and increase the frequency of astigmatism. Additionally, an analysis of the astigmatism’s frequency depending on the tumor localization was made. Patients with central or paracentral localization of the tumor lesion amounted to 69.4 % (n = 25), and from the peripheral — 30.6 % (n = 11) (p = 0.002).Conclusions. In this paper, we analyzed the frequency and nature of refractive errors in children with monolateral and bilateral retinoblastoma. The identified risk factors may affect the development of refractive amblyopia in children with retinoblastoma in more adulthood, which requires the development of an individual approach to the correction of refractive disorders taking into account the localization of tumor foci, the nature of the lesion and the individual characteristics of patients.

Abstract:
Purpose: to study the effect of differentiated treatment approach in patients with varying degrees of severity chronic ocular ischemic syndrome (OIS) on clinical course of disease and hemodynamics of eyes in prospective research.Patients and methods. The research included 20 patients with chronic OIS. Patients were divided into 4 groups due to severity of chronic OIS and type of treatment. 1st group — 7 patients with moderate severity chronic OIS and hemodynamically significant of internal carotid artery stenosis (ICAS); only carotid endarterectomy (CE) of ICAS was performed. 2nd group — 6 patients with severe degree chronic OIS and hemodynamically significant stenosis of ICAS; 2 weeks before CE, panretinal photocoagulation (PRP) of retinal capillary non-perfusion areas was performed. 3rd group — 4 patients with severe degree chronic OIS, complicated by rubeosis iris and increased IOP on hypotensive regimen, on the background of hemodynamically insignificant ICAS; PRP of retina was performed. 4th group — 3 patients with moderate severity chronic OIS with hemodynamically insignificant ICAS; course of neuroprotective therapy was performed. All patients underwent standard and specialized ophthalmologic examination methods. Assessment of blood flow in brachiocephalic vessels, eye vessels was performed by ultrasound scan, spiral computed tomography, OCT-angiography with the AngioVue.Results. Monitoring of patients’ groups for 1 year after chronic OIS treatment allowed us to determine tactics of patient management depending on degree of ICAS and severity of chronic OIS. Reconstructive surgery at hemodynamically significant ICAS caused positive dynamic in intraocular blood flow, which contributed to improvement and preservation of BCVA in 71 % of patients. Preventive PRP of retina, before performing reconstructive surgery of ICAS, optimized and reduced the time of visual recovery. PRP of retina as independent method of treatment of chronic OIS, complicated by neovascular glaucoma, caused full or partial regression of neovascularization in iris, which increased possibilities of its effective treatment. Neuroprotective pharmacotherapy in early stages of chronic OIS, in absence of indications for reconstructive surgery and PRP of retina, improved the prognosis for patients’ vision.Conclusion. Differentiated treatment approach in patients with chronic OIS, due to changes of hemodynamics of internal carotid artery, has improved indexes of hemodynamic and visual acuity.

Abstract:
Micro incision vitrectomy surgery with removal of epiretinal and internal limiting membranes is used for treating various forms of vitreomacular traction syndrome.Objective: to study the condition of retinal microcirculation using the OCTA method in the patients with traction maculopathy and macular ruptures before and after vitrectomy.Patients and Methods. The study included 160 patients, of which 55 had epiretinal fibrosis (Treatment 1), 60 had macular ruptures (Treatment 2), and 45 with no ophthalmic pathology (Control). Treatment 2 group included two subgroups: 2a — patients with large-diameter ruptures (over 800 μm) subject to inverted internal limiting membrane flap technique (n = 12), and 2b — patients with 430–800 μm ruptures subject to rapprochement of the rupture edges with a platelet mass technique. All patients underwent conventional ophthalmology examinations and optical coherence tomography angiography (OCTA) using Sirrus HD-OCT 5000, Carl Zeiss, Germany.Results. In the postoperative period, there was an improvement in retinal microcirculation in the Treatment 1 patients, and the values of both perfusion and vascular densities increased. A month later, an additional improvement of these indicators was recorded against the background of a decrease in retinal thickness and restoration of the vitreoretinal interface configuration. In the early postoperative period, Treatment 2 patients showed significant difference in the capillary density of the superficial vascular complex from the control group. A month later, the density of blood vessels in the Treatment 2 patients achieved control group values. Despite an immediate increase in perfusion measurements after surgical treatment, their values in a month were still lower than in the control group.Conclusions. In the patients with epiretinal membrane and macular ruptures, a statistically significant decrease in both vascular and perfusion densities of the surface capillary complex was revealed by OCTA. The effects of vitreoretinal surgery performed on Treatment 1 and 2 patients with macula traction pathology included increased visual acuity, decreased retinal thickness, and restoration of the proper vitreoretinal profile. Based on OCTA results, we discovered a gradual increase in vascular density of the macula in Treatment 1 and 2 patients after surgical treatment of VMT syndrome. Retinal perfusion in the macular region of Treatment 1 patients achieved the values of the control group within a month, while in Treatment 2 patients they increased, but remained lower than in control group. OCTA is a highly informative method for the diagnostics and monitoring of the eye posterior segment condition in the patients with VMT syndrome.

Abstract:
Purpose: to evaluate the immediate and long-term hypotensive efficacy, the number of complications, and the clinical benefits of a draining autovalve limbosclerectomy (DALS) performed using a kit of disposable instruments in patients with POAG of various stages in comparison with trabeculectomy (TE).Patients and Methods. The study is based on the analysis of the clinical and functional condition of 127 eyes of 127 patients with primary open-angle glaucoma (stage I POAG was detected in 2 eyes, stage II in 30 eyes, stage III in 88 eyes and stage IV in 7 eyes). Patients were divided into groups: the main group—76 people who underwent DALS using a set of disposable instruments, and the control group—51 people who underwent TE. The average age of patients is 68.9 ± 10.3 years. Before and within 24 months after surgery, all patients underwent standard diagnostic examinations. The initial level of IOP against the background of the maximum antihypertensive mode varied from 24 to 50 mm. Hg. According to gonioscopy, the angle of the anterior chamber was open in all cases (III–IV degree). Patient exclusion criteria: history of laser or surgical treatment of glaucoma, cataract treatment.Results. After 24 months of follow-up after DALS, the level of IOP in patients with stage I–II of POAG was 14.19 ± 1.83 mm Hg and with III–IV stage of POAG 14.95 ± 2.15 mm Hg, compensation was achieved in 88.2 % of patients without the use of antihypertensive drops. After TE, compensation was received in 72.6 % of patients, the IOP level was 16.9 ± 2.21 and 17.78 ± 2.31 mm Hg. respectively (p < 0.01). After DALS surgery, a decrease in the number of complications was revealed in comparison with TE: a decrease in сiliochoroidal detachment by 9.1 %, hyphema by 2.5 %, ophthalmic hypertension in the early p/o period by 3.2 %, cystic changes in the filtering bleb by 7.1 %.Conclusion. The standardized DALS operation using a disposable tool kit is a new highly effective and safe method for the surgical treatment of glaucoma. DALS may be the operation of choice in the treatment of POAG of all stages.

Abstract:
Drug dependence is one of important social problems in modern society. It became more actual because of the high morbidity in young working-age patients. The central nervous system is the main target for psychoactive substances. Long-term drug intoxication results in functional and structural brain alterations, it leads to cognitive impairment and disturbances of higher mental functions rendering patients’ disadapted in their work and daily life activities. Eye disorders due to drug abuse are multifaceted and can vary from conjunctival damage to severe endogenous endophthalmitis. Opioid dependence can result not only from intentional self-administration of narcotic drugs, but also from long-term prescribed use of these medicinal products owing to their potent analgesic effect exhibited in somatically ill patients with severe chronic pain. Opioid derivatives act as partial or full agonists of three types of opioid receptors (δ, κ, and µ) extensively expressed by the neurons of the central and, to a lesser extent, peripheral nervous system. The most dangerous complication of intoxication with this group narcotic drugs is opioid induced-respiratory depression resulting in hypoxaemia and hypercapnia. The paper presents a case report of bilateral optic nerve atrophy that developed in a young female patient after a long period of intravenous heroin use. There are practically no reports of optic nerve damage due to heroin intoxication in the current literature. Possible optic nerve atrophy mechanisms under discussion include generalized hypoxia developing against a background of chronic heroin intoxication and direct toxicity of admixtures used to dilute home-made narcotic drugs. In view of the growing use of these substances, physicians have to consider their effects in the differential diagnosis in patients with atypical eye disorders.

Abstract:
The presence of concomitant corneal astigmatism is the most common cause of low visual functions in patients with surgical treatment of cataracts. The implantation of toric intraocular lenses is procedure of choice in the correction of corneal astigmatism from 1.0 DPT and more in patients with cataracts. Successful results depend on several factors, the most important of which: the correct and stable position of the intraocular lens (IOL) in the capsule bag, the absence of residual astigmatism, the choice of the implanted IOL’s model, taking into account material and design of lens elements. Deviation of the cylindrical component by 10 degrees reduces visual acuity up to 35 %. Repeated intervention for the purpose of toric lens reposition, according to the literature, varies from 0,65 to 9 % and is carried out with the rotation of IOL more than 10°. Femtolaser-assisted phacoemulsification allows partially automate the surgical process, making it more efficient and safe, creating a theoretical advantage over manual techniques of surgery. In practice, the capsulorexis formed by the femtolaser is characterized by a regular rounded shape with a given diameter and provides a coating of optical part of IOL for 360°, which, according to various sources, contributes to a lesser degree of decentralization and tilt of the lens in the capsule bag and can be considered as one of the reasons for obtaining a more accurate refractive result and, as a consequence, higher visual functions. The review presents the results of clinical studies of corneal astigmatism correction during standard and femtolaser-assisted phacoemulsification with implantation of various models of toric IOLs: visual acuity, rotational stability, residual astigmatism percentage, wave front change. Researchers continue to discuss the advantages and disadvantages of modern technologies. However, the problem of increasing the predictability of the surgical outcome in order to obtain a higher refractive result both in the early and in the long-term postoperative period remains unquestionable.
