Purpose. Description of a clinical case of an iris floccule in a girl of 17 years old. Material and methods. 17-year-old patient who complained about a decrease in vision of the right eye and a change in the shape of the pupil. she was examined by visimetry, biomicroscopy, tonometry, ophthalmoscopy. 3 years ago she was consulted at the ophthalmology center, where there was revealed lysoriness and changes in the eyes. No surgical or laser treatment has been proposed. Changes in the area of pupil's parents noticed in early childhood, in the last 3 years the changes increased. Result. The patient was assigned midriatics, to open the optical zone and improve visual acuity, recommended consultation to resolve the issue of surgical or laser removal of brush-shaped floccules to eliminate obscuration and prevent amblyopia. Conclusion. Clinical case indicates that timely surgical treatment is necessary to achieve results. Treatment should be carried out as soon as possible, since vision loss is a high-risk area for the development of obscurative amblyopia. Key words: iris flocculi, vascular abnormalities.

Hemifacial Microsomia (HFM) is a term used to identify facial deformities associated with the development ofthe first and second pairs of branchial arches, characterized by underdevelopment of one half of the face. One typeof hemifacial microsomia is oculo-auriculo-vertebral dysplasia or Goldenhar syndrome.The incidence of HFM is 1:3500-1:7000 of live births and occurs in 1 case per 1000 children with congenitaldeafness. The ratio of boys to girls is 3:2. The etiology and type of inheritance is studied insufficiently. There are threepossible pathogenetic models: vascular abnormalities and hemorrhages in the craniofacial region, damage of Meckel'scartilage, and abnormal cell development of the cranial nerve crest. Environmental factors, maternal internal factors,and genetic factors (OTX2, PLCD3, and MYT1 mutations) may also cause the development of hemifacial microsomia.The article demonstrates a clinical case of hemifacial microsomia in a newborn boy from a mother with Z-21 inthe form of deformation of the left auricle with atresia of the auditory canal and "false" ears on the right, combinedwith congenital anomaly of heart (atrial septal defect) and brain (hypoplasia of the corpus callosum).Emphasis is placed on the need of involving a multidisciplinary team of specialists in the management of thispatient both in the neonatal period and in the system of subsequent follow-up.

A 3-year-old girl presented with sudden onset of bilateral vision loss on waking up from sleep. There had been no associated eye pain, eye redness, fever or history of trauma in the days leading up to the presentation. She had been diagnosed with Evans syndrome at the age of 18 months and started on a regular dose of oral prednisolone under regular follow-up at the paediatric clinic. Upon presentation, her visual acuity was light perception bilaterally, with relative afferent pupillary defect in the right eye and sluggish pupils bilaterally. Bilateral fundus examination showed normal macula and pink optic discs without papilloedema. Other systemic examinations were unremarkable. The provisional diagnosis was severe bilateral retrobulbar optic neuritis, prompting further investigations to rule out infectious or vasculitic causes. Extensive investigations were carried out during admission including infective screenings of blood and urine, all of which were negative. A contrasted magnetic resonance image of the brain showed both orbital segments were swollen and appeared hyperintense, with involvement of the intracanalicular and intracranial segments, suggesting an inflammatory or demyelinating aetiology. A visual evoked potential test to rule out demyelination disease was also normal. As intravenous methylprednisolone treatment appeared to have a slow effect, the treatment was switched to intravenous gammaglobulin. The patient responded well to treatment, and her latest visual acuity assessment 1 month after presentation showed bilateral vision of 6/24. This is the first-ever Evans syndrome patient to be reported worldwide with bilateral optic nerve sterile inflammation.

Primary endothelial dystrophy of the cornea is a fairly common disease in people older than 50 years. Well-developed methods of conservative treatment, as a rule, do not lead to improvement or stabilization of the functional state of the cornea. The choice of tactics of surgical treatment from the existing variety of techniques is complicated. There are isolated reports of the restoration of corneal transparency after descemet membrane removal. The author's method of endothelial corneal dystrophy treatment addressed in this particular clinical case - a combination of isolated descemetorhexis and collagen cross-linking - resulted in impressive increase in visual acuity and significant improvement in objective criteria for the morpho-functional state of the cornea.

The study objective is to describe a clinical case of a rare disorder of the cerebellum, Lhermitte–Duclos disease.Clinical case. The Federal Neurosurgical Center (Novosibirsk) admitted a male patient, 40 years old. Medical history showed that in 2017 he underwent ventriculoperitoneal shunt due to hypertensive hydrocephalus syndrome caused by space-occupying mass of the right hemisphere of the cerebellum. In June of 2017, the patient was consulted by a neurosurgeon. Later, an increase in the mass, partial atrophy of the optic disks were observed. Due to the patient’s complaints of headache, ataxia, vertigo, as well as insufficient effect of the shunt, microsurgical removal of the space-occupying mass in the cerebellum by right paramedian suboccipital craniotomy was performed. Gangliocytoma removal was performed under constant neurophysiological control which allowed to fully resect the gangliocytoma inside intact brain tissue. Histological and immunohistological examinations allowed to diagnose grade I dysplastic gangliocytoma of the cerebellum (Lhermitte–Duclos disease). In the postoperative period, brain symptoms regressed fully, vestibulocerebellar syndrome persisted. The patient was discharged in satisfactory condition. No negative dynamics were observed in 7 months of follow-up.Conclusion. Due to the rareness of Lhermitte–Duclos disease, currently there are no established approaches to treatment, however, in symptomatic course there are indications for surgical removal of the gangliocytoma. Radicality of resection should be correlated with the risk of neurological defects. In our case, surgical treatment allowed to improve the patient’s condition, prevent further progression of the gangliocytoma and obtain an accurate histological diagnosis.

Introduction Iodine deficiency is a leading cause of preventable physical and mental retardation. Potassium iodate is used for iodine supplementation to prevent iodine deficiency. We herein report a case of toxic retinopathy following intentional ingestion of potassium iodine. Case Presentation A 41-year-old male presented with a 5-day history of blurred vision in both eyes. His visual acuity (VA) was hand motion and his pupillary reactions were sluggish bilaterally. The fundus examination revealed bilaterally diffuse retinal pigment epithelium atrophy and secondary pigmentary changes at the posterior pole, but his peripheral fundus was relatively spared. Choroidal thinning, punctate hyperreflective dots along the retinal pigment epithelium layer, and outer retinal atrophy were the optical coherence tomography findings, which were consistent with widespread areas of retinal pigment epithelium window defects observed on fundus fluorescein angiography. The visual evoked potential test showed no response in the right eye and revealed a delay in the latency and a decrease in the amplitude of the P100 wave in the left eye. Wave b responses of the photoreceptors could not be observed in the patient’s electroretinogram. After a vitamin supplementation protocol consistent with the literature, at the 4-month follow-up visit his visual acuity had improved to 0.3 in the right eye and counting fingers in the left eye. Conclusion Potassium iodate toxicity is a cause of serious retinal and choroidal damage and results in severe vision loss. Hydration, hemodialysis, and antioxidants can be helpful to minimize the complications.

Abstract Background Visual impairment occurred as an infrequent form of chemotherapeutic toxicity and was often underestimated despite of several reports. We described a case of acute unilateral visual impairment after one cycle of intravenous chemotherapy of a normal dose, aiming at raising attention to chemotherapy-induced ocular toxicity. Case presentation The patient developed a progressive vision loss in the right eye during the chemotherapy. After one cycle of intravenous chemotherapy, her visual acuity decreased by 0.6 in the right eye (VOD = 0.4) compared to the previous value of 1.0 (VOD = 1.0). No evidence of ocular infiltration was observed from the cerebral magnetic resonance imaging (MRI). During her follow-up period, we documented the ophthalmologic examinations including visual acuity, visual field (VF), visual evoked potential (VEP), electroretinogram (ERG), fundus photograph (FP), fundus fluorescein angiography (FFA) and optical coherence tomography (OCT). Ophthalmoscope examination and fundus photograph showed optic disc edema, fuzzy boundary and linear hemorrhages in her right eye. Fundus fluorescein angiography (FFA) revealed capillary underdevelopment at the nasal and superior temporal area of the optic disc in the early phase and capillary fluorescein leakage in the late phase. The result of VEP test suggested the impaired function of the optic nerve. Thus, a diagnosis of nonarteritic anterior ischemic optic neuropathy (NAION) was made by the ophthalmologist according to these results. The patient was prescribed prednisone combined with neuroprotective drugs, which did not work. After the cessation of chemotherapy, her impaired vision gradually recovered. Conclusions This is the first reported case of acute visual impairment in a patient who underwent chemotherapy of a normal dose. It is indicated that while receiving benefits from chemotherapy, cancer patients simultaneously suffer from the risk of vision loss.

ntroduction. A distinctive feature of kidney cancer is a frequent, compared with other tumors, spread of the tumor through the venous collectors (in the renal and inferior vena cava up to the right atrium), along the path of least resistance to invasive growth.The aim of the study was to present a clinical case of radical treatment of kidney cancer involving extensive IVC thrombosis.Materials and methods. The study describes a clinical case of radical treatment of patient M. with kidney cancer involving extensive IVC thrombosis, extending to the right atrium (written informed consent for patient information and images to be published was obtained prior to the study). During preoperative examination, the patient was diagnosed with renal cell carcinoma with non-occlusive hypervascular tumor thrombus of the renal vein, the inferior vena cava and the right atrium based on the findings of ultrasound examination (transabdominal and transthoracic, and transesophageal), multislice computed tomography (MSCT) and magnetic resonance imaging (MRI).Results and discussion. Surgical treatment remains the main method of treatment of renal cell cancer, moreover, the inferior vena cava thrombosis cannot serve as a cause for refusing surgical treatment. The thrombus spreading along the venous collectors is an important factor in determining the tactics of surgical treatment. The length of the tumor thrombus, as well as the degree of its fixation and ingrowth into the vein wall is of great significance for planning surgical techniques and predicting clinical outcomes. Based on various methods of radiological examination, patient M. was diagnosed with cancer of the right kidney, 3 stage T3cNxM0, IVC tumor thrombus, paraneoplastic syndrome (hyperthermia), right-sided nephrectomy with aortocaval lymphadenectomy, thrombectomy from the IVC, vascular isolation of the liver, resection of the IVC, thrombectomy from the right atrium combined with cardiopulmonary bypass.Conclusion. Despite the technical complexity of nephrectomy with thrombectomy from the IVC, especially in the presence of a massive supradiaphragmatic thrombus, these interventions have no alternatives if a radical treatment is to be achieved. Step-by-step support using radiological methods of investigation is an important aspect of patients preparation; this allowing determining the exact volume of the damage and non-invasively assessing clinical outcomes of surgical treatment.

Posterior Keratoconus

Purpose: To provide a clinical case of recurrent keratoconus from our practice.Materials and method. A patient came to the clinic with a complaint of decreased visual acuity in the right eye. A series of standard instrumental examinations and Scheimpflug keratotopography were performed, and astigmatism of the right eye was diagnosed. Similar examinations were carried out during the patient’s attendance at follow-up examinations.Results. Based on the results of scanning Scheimpflug keratotopography, the diagnosis of keratoconus (forme fruste) was made. On examination after 1 year, there were no complaints of decreased visual acuity and data from the same instrumental examinations indicating keratoconus. After this examination, the patient came 3.5 years later with complaints of a new decreased visual acuity in the right eye. During instrumental examinations and keratopography, data were obtained indicating the presence of posterior keratoconus. After 1 year, a follow-up examination took place without complaints. The data of instrumental studies are identical to the previous visit; keratotopography revealed a decrease in posterior elevation.Discussion and conclusion. It was revealed that the patient was constantly taking the hydroxyurea drug against the background of systemic disease up to the 3rd visit, at the time of the 4th visit she had not taken it for 1 year. There are publications in the literature on the effect of this type of drugs on the collagen of the dermis of the skin, the type of which corresponds to the collagen of the cornea. We hypothesize that drugs may have an effect on the biomechanical properties of the cornea, which requires further in-depth study.
