Abstract	In this study, the influence of the application of an online teaching model on the development of digital cometences of future teachers in preschool institutions was examined. The research that this study deals with was carried out on a sample consisting of N=125 students of the 3rd year of basic academic and professional studies in the study program of teacher in preschool institutions. As a research instrument, a five-point Likert-type scale of attitudes was used. The results show that there is a statistically significant difference in the attitudes of future teachers in preschool institutions when it comes to self-assessment of digital competencies before and after the implementation of online classes during the state of emergency in Serbia during the Sars-Cov-2 virus pandemic. The conclusion of the study is that the implementation of online teaching in processing the content of the Methodology of getting to know the environment affects the improvement of the digital competences of future educators when it comes to: 1) creating digital resources; 2) application of digital technologies in immediate educational work; 3) the role of digital technologies in professional development. The results of this research can be used to encourage teachers to step out of the usual pre-pandemic practice and enrich their pedagogical work with combined teaching (hybrid model) where part of the material would be analyzed in person, and part would be analyzed online using web tools, websites and videoconferencing applications.

Abstract	Introduction. Ankyloblepharon filiforme adnatum (AFA) is a rare congenital abnormality of the eyelids that has been reported as an isolated anomaly, but may also be associated with other anomalies or as a part of well-defined syndromes. The aim of this work was to present a case of familial AFA associated with bilateral cleft lip and palate. Case outline. A full-term female newborn (40 weeks’ GA, BM 3,700 g) had bilateral partially fused eyelids at birth, associated with a cleft lip and palate. The surgical treatment was performed five days after AFA was diagnosed. The baby’s mother also had AFA, without a cleft lip or palate. The baby girl has been followed up by a plastic surgeon, a specialist in orthodontics, as well as an ophthalmologist and a pediatrician. Conclusion. This case indicates familial clustering of AFA, whereby it assumes a more severe form in the following generation. A cleft lip and palate in our patient has required surgical treatment, oral and dental rehabilitation, as well as the need for more intensive care and regular follow-ups by multidisciplinary teams.

Abstract	Introduction. The treatment of dry eye by autologous serum is a simple and inexpensive treatment option. It is particularly effective in severe forms of dry eye as well as for chemical eye injuries, and it is justified by the presence of essential tear components which are not found in preparations of artificial tears. The aim of this study was to analyze the effects of autologous serum therapy in the patients with dry eye. Material and Methods. We monitored the effect of one-month treatment of dry eye by autologous serum (used with artificial tear preparations) in 50 rheumatology patients (23 men and 27 women) aged 26-65 years at the Department of Ophthalmology, Clinical Center Nis. We analyzed ocular discomfort and the values of objective parameters for the evaluation of tear film at baseline and one month later (Schirmer I, Tears Break Up Time and Rose Bengal). Results. A statistically significant reduction of subjective complaints was found in the patients after the treatment by autologous serum (p<0.05), along with a minimal improvement of objective tests for checking the tear film quality. Discussion and Conclusion. The use of autologous serum in dry eye therapy should provide benefit to the patients, relieve symptoms and improve objective parameters for the evaluation of dry eye. Both doctors and patients should be adequately informed, and proper screening of potential users of this method should be done. Not only additional tests of therapeutic effect of autologous serum (as well as of umbilical cord serum or autologous plasma) are needed but also parallel clinical and histopathological examination and analysis of the effects of this type of treatment of dry eye.

Abstract	Introduction/Objective. Intensive oxidative stress is proven in patients with diabetes mellitus and important in the development of a microvascular complication of type 2 diabetes mellitus. The aim of the study was to investigate the relationship between morphometric parameters of retinal blood vessels in patients with diabetic retinopathy (DR) and the levels of parameters of oxidative stress: advanced oxidation protein product (AOPP), thiobarbituric acid reactive substances (TBARS), and total sulfhydryl (SH) groups in blood samples. Methods. The patients (the group with DR and controls) were sex- and age-matched. Glycaemia, hemoglobin A1C HbA1C, total cholesterol and its fractions, and triglycerides were measured in blood samples. AOPP and total SH groups were determined in the plasma by specific methods. Modification of the thiobarbituric acid method was used for the determination of TBARS. The number and diameter of retinal blood vessels, as morphometric parameters on digital retinal photography, was determined by using the ImageJ software. Student’s t-test was used as the statistical method for the evaluation of differences between the morphometric and blood test parameters. The significance of differences in morphometric parameters of retinal blood was establish by one-way ANOVA. Results. Significantly higher levels of parameters of oxidative stress (AOPP and TBARS) were in the group of patients with DR than in the controls. This difference was also present among the patients with mild and severe forms of DR (AOPP F 77.03, p < 0.001) (TBARS F 63.28, p < 0.001). The diameter of retinal blood vessels correlated with levels of AOPP, but only in patients with mild DR. Conclusion. Parameters of oxidative stress, AOPP and TBARS, may be important for the follow-up of DR. In early stages in diabetic retinopathy, AOPP can be a valuable biomarker.

Abstract	Endocrine orbitopathy or ophthalmopathy is an organ-specific, genetically conditioned autoimmune disease, resulting from a thyroid disorder. It is the most common cause of unilateral and bilateral proptosis in adults. Endocrine orbitopathy occurs most frequently in women aged 30 to 50 years. Ultrasound diagnostic is of primary importance in orbital pathology because of its safety, non-invasiveness, rapid application, and no need for preparation of the patient. The A scan in endocrine orbitopathy shows the echographical widening of the peripheral orbital space, a widening of the muscle echo, and the B scan shows a high internal echo of the connective tissue septa, increased reflection of the muscle belly, and distension of the retrobulbar optic nerve sheaths, enlargement of lacrimal gland and dilatation of the superior ophthalmic vein. All ultrasound features of the endocrine orbitopathy can be explained by immunological abnormalities and histological changes in orbital adipose tissue and extraocular muscles.

Abstract	Eales disease is characterized by three overlapping stages of retinal vasculitis, occlusion, and neovascularization. Diagnosis is mostly clinical, and its etiology appears to be multifactorial. A 26-year-old woman with manifesting vasculitis of the peripheral retina, retinal neovascularization, and vitreous haemorrhage is presented. Depending on the stage of the disease, its management consisted of medical treatment with corticosteroids in the active inflammatory stage and laser photocoagulation in the advanced retinal ischemia and neovascularization stages. Multiple delicate ocular surgeries were performed due to recurrent vitreous haemorrhage and retinal detachment. The experience acquired in this treatment is evidence of the necessity for treatment immediately after the confirmation of Eales disease. The decision to carry out intensive laser treatment and surgery at the right time could improve the prognosis of Eales disease.

Abstract	Introduction. Identical twins account for 0.2% of the world population and 8% of all twins. A “mirror image” variation can be found in 25% of identical twins. Studies of twins assume a special place in human genetics due to the possibility of comparing genetic and other factors. We present two pairs of identical male twins with mirror-image astigmatism and esotropia. Case Outline. The first was a pair of twelve-year old identical twins with “mirror image” myopic astigmatism. The Twin 1 had myopic astigmatism in the right eye, while the Twin 2 was affected by the left eye myopic astigmatism. The second was a pair of six-year old identical twins with esotropia and hypermetropic astigmatism. The Twin 1 had esotropia in the left eye, while the right eye was affected in the Twin 2. Esotropia was surgically corrected. Conclusion. In this study we pointed to the role of genetic factors in the development of refractive error, as well as the type of strabismus. Refraction anomalies (myopia, hypermetropia and astigmatism) are complex heterogeneous disorders and ideal for genetic investigation. The knowledge of genetic mechanisms involved in refractive error susceptibility may allow treatment to prevent progression or to further examine gene-environment interactions. We hope that this paper will initiate further investigation of refraction anomalies in twins and future multicentre studies, which, to our knowledge, have not been conducted in our country so far.

Abstract	Introduction. Multifocal choroidopathy syndromes are a group of rare disorders, which involve a primary pathologic process occurring at or near the level of the retinal pigment epithelium, with or without choriocapillaris involvement. The aetiology of multifocal choroidopathy syndrome is still unknown. A case report. We present a case of multifocal choroidopathy syndrome. A 54-year-old woman was referred to our department with blurred vision on both eyes, mild ocular pain, accompanied by metamorphopsia, floaters, scotomas and photopsia. The anterior segment examination showed small to medium size keratic precipitates, posterior synechiae, and iris atrophy. Mild to moderate aqueous inflammation with cells and flair was present in the anterior chamber. The fundus examination showed multiple small yellow-white spots, round-shaped changes located at the level of the retinal pigment epithelium and choriocapillaris. According to the fluorescein angiography the active lesions exhibited blockage of the early choroidal fluorescence followed by late staining. The old inactive lesions corresponded to the retinal pigment epithelium windows defects. The laboratory examination showed high level of blood glucose, C reactive protein, cholesterol HDL, LDL, triglycerides. According to the immunological examination the C3 component of complement was lower (0.630), as well as the C4 component of complement (0.158), and the immunological complex in blood was elevated (171). ELIZA test on viral infection showed Citomegalo viruses IgG positive, Herpes Simplex Virus IgG positive, Varichela Zoster Virus IgG positive. The results of human leucocyte antigen typization were human leucocyte antigen A1:A2, human leucocyte antigen A2:A24(9), human leucocyte antigen B1:B44(12), human leucocyte antigen B2:B60(40), human leucocyte antigen C1:Cw3, human leucocyte antigen C2:Cw5. The radiological examination of lungs, the Mantoux test, Treponemal serology, Toxocara and Toxoplasma serology, magnetic resonance of endocranium and orbit were also performed. The multiple viral infection, which was detected in our patient with immunological abnormalities pointed to an underlying autoimmune mechanism, possibly triggered by an infectious agent, a virus.
