The Corona virus infection started at the end of 2019 in Wuhan - China and spread rapidly throughout the world, generating the Covid 19 pandemic. The manifestations of the Covid disease were extremely varied, from a simple flu, with fever, cough, weakness, headache, joint pain, up to severe pneumonia, with severe acute respiratory syndrome (SARS-Cov2) and even death. The symptomatology of the disease, the evolution and the complications that appeared varied, depending on the associated pathology - diabetes mellitus (DM), hypertension (HT), the age and the immune status of the patient. Aim: The ocular manifestations related to Covid 19 were mostly represented by conjunctivitis, but the neurotropic character of Corona virus could justify the appearance of certain neuro-ophthalmological manifestations, such as: optic neuritis (ON), cranial nerve palsies, visual field (VF) anomalies. The aim of this paper was to research the cases of optic neuropathy post-Covid 19, published in the specialty literature between 2020 and 2022. The following were evaluated: risk factors, distribution by age group and gender, evolution and complications, as well as the clinical forms of optic neuropathies. Materials and methods: We used Google Scholar and PubMed databases to find articles on optic neuropathies related to the Covid-19 infection. We followed the articles published during the pandemic and selected 21 cases, belonging to 17 authors, irrespective of their origin and the language in which they were written. Results: 21 patients affected by ON in the Covid-19 disease, 11 women and 10 men, were mentioned. The optic neuropathies described by the authors were: retrobulbar optic neuropathy, only one associated with myelin oligodendrocyte glycoprotein (MOG), papillitis, neuroretinitis, anterior ischemic optic neuropathy (AION), out of which one arteritic anterior ischemic optic neuropathy (AAION) and the others non-arteritic anterior ischemic optic neuropathy (NAAION), one being related to pronation in an oro-tracheal intubated (OTI) patient with acute respiratory distress syndrome (ARDS). Discussions: The neuro-ophthalmological complications associated with Covid 19 disease can be severe, so the patients should be monitored continuously. Many investigations (serological, immunological and imaging exams) are necessary to exclude other etiologies of ON. Conclusions: A complete ophthalmological exam is mandatory for each patient diagnosed with Covid 19 disease, even if they have ocular manifestations or not.

Objective: The aim of this report is to highlight a rare condition that raises serious diagnosis and treatment difficulties. Case presentation: A 34-year-old male patient presented at the Department of Ophthalmology accusing reduced visual acuity (VA), dyschromatopsia and slight photophobia in his left eye (OS). Posterior pole examination revealed serous retinal detachment superior to the optic nerve head in his right eye (OD) and a well-defined macular oedema in the OS. Optical coherence tomography (OCT) confirmed the presence of subretinal fluid accumulations, fundus fluorescein angiography (FFA) revealed punctate hyperfluorescent pinpoint foci in the macular region of both eyes in the early venous phase and dye pooling in the late phase. The first diagnosis was Probable Vogt-Koyanagi-Harada (VKH) syndrome, but the evolution under corticosteroid therapy and shifting of the position of the serous retinal detachments in time, changed the diagnosis to multifocal, recurrent central serous choroidopathy. The patient received treatment with anti-vascular endothelial growth factor (VEGF) agents and presented multiple episodes of partial remission and shift of the subretinal fluid. Conclusions: The persistent, recurrent, multifocal and bilateral exudative retinal detachments raised significant diagnosis difficulties. In the absence of a well-established treatment, the current prognosis is unfavorable.

Objective: This study aimed to determine the intravitreal concentration of VEGF in eyes with PDR and to evaluate the effects of previous PRP on its level. Methods: It was a cross-sectional study performed at the Clinical Centre University. It included 90 eyes surgically treated with PPV, divided into three groups, group A - patients with PDR with previous PRP, group B - patients with PDR without previous PRP, and group C - PPV performed due to the indication unrelated to diabetes. A vitreous sample was obtained during PPV, and the VEGF concentration was determined using an Enzyme-linked immunosorbent assay test (ELISA). Shapiro-Wilk, nonparametric tests Kruskal-Wallis, Mann-Whithney U test, ANOVA and Spearman's correlation test were used. Results: The highest vitreous VEGF concentration was in group B - 972.96 (743.33-1149.13) and was higher than in group A - 69.22 (37.33-225.15) and in group C - 19.93 (1.15-32.17) (p<0.001). There was a positive correlation between VEGF vitreous concentration and glucose level in group A patients (Rho=0.410; p=0.027). Conclusion: As a treatment before PPV surgery, PRP showed to be effective in the reduction of VEGF levels, which also highlighted a decrease in complications during and postoperatively.

The modern glaucoma surgeon is faced with many surgical alternatives for the management of glaucoma. In recent years, numerous techniques that make Schlemm's canal (SC) more accessible for surgery by being less invasive and surgically less challenging were introduced. Since its first introduction, canaloplasty has become a well-established method of glaucoma surgery. The aim of this paper was to present an overview of canaloplasty and its modifications, and to highlight their strong points and potential drawbacks based on available data on the effectiveness of each technique. Furthermore, it offered an overview of the development of canaloplasty over time and the clinical aspects that should be considered in patient selection.

Purpose: Infectious atypical optic neuritis (AON), like tubercular, is a vision threatening condition with phenotypic overlap with Neuromyelitis Optica Spectrum Disorder (NMOSD). The overlapping neurological manifestations and negative AQP4-Ab-assay make it difficult to discover the primary cause of neuritis. Case presentation: We report two paediatric cases with NMOSD that did not fulfil the diagnostic criteria. Moreover, associated undiagnosed tuberculosis at the time of presentation and negative AQP4-Ab clouded the diagnosis and delayed the treatment. The first case was initially diagnosed with infectious optic neuropathy. By the time steroids were started, optic atrophy had already set in. The second case had optic neuritis, LETM, and intracranial-tuberculomas with no signs of pulmonary-tuberculosis with negative CSF-analysis. So, systemic steroids were started promptly. The history of LETM in both cases raised the suspicion of NMOSD. Conclusion: The importance of accurate clinical diagnosis and early intervention in cases of AON was emphasized in a limited resource country, that could potentially result in salutary visual outcomes, especially in the paediatric age group Abbreviations: AON = atypical optic neuritis, TB = tuberculosis, NMOSD = neuromyelitis optica spectrum disorder, LETM = longitudinal extensive transverse myelitis, AQP4-Ab = anti-Aquaporin-4 Antibodies, RE = right eye, LE = left eye, MRI = magnetic resonance imaging, CSF = cerebrospinal fluid, ATT = anti-tubercular treatment, DOV = diminution of vision.

Objective: The aim of this study was to determine the efficacy of hAM plug in the treatment of idiopathic macular hole and to see its post-operative visual improvement and anatomical apposition. Material and methods: 10 eyes of 10 patients who had idiopathic MH underwent a pars plana vitrectomy (PPV) with the hAM plug implanted in MH. The patients were followed up on 2nd day, 1st week, 3rd week, 6th week and 3rd month. Results: Final anatomical closure of MH was achieved in all the cases. BCVA improved from 0.91±0.11 logMAR to 0.28±0.06 logMAR after 3 months. No adverse event was documented in the specified period. Conclusion: hAM plug is an efficient method to treat and manage idiopathic MH with encouraging results both in terms of anatomical closure and visual acuity gain.

Purpose: Slowing ectasia progression is critical for maintaining visual potential in keratoconus (KC), for which various therapeutic approaches have been implemented. A Pentacam Scheimpflug imaging device was used to quantify contact lens (CL)-related changes in keratoconus corneal topographic indices. Methods: Thirty KC patients (group 1; 60 eyes) were using one of the three CL (rigid gas-permeable CL (RGPCL)-10, hybrid CL (HCL)-10, and scleral CL (SCL)-10 patients). A control group included 30 KC patients (group 2; 60 eyes) not using CLs due to intolerance or inappropriateness. The Pentacam® HR Scheimpflug imaging device was used to measure topographic indices such as Km anterior, Km posterior, K max, corneal thickness (CT, corneal central, apex, and thinnest), corneal volume (CV), anterior chamber volume (ACV), and anterior chamber depth (ACD) at baseline, 3rd, 6th, and 12th months. Results: The mean ages for groups 1 and 2 were 32±10 and 31±09 years, respectively. Group 1 had a lower but statistically significant change in K max than group 2 (p<0.038). Also, group 1 had a minor but non-significant decrease in anterior and posterior keratometry values compared to group 2 (pKm ant. right/ left eye = 0.063/ 0.065 and 0.087/ 0.094, respectively). RGPCL users had significant changes in central CT, thinnest CT and ACD (p<0.041). SCL users had more stable changes than other CLs for the thinnest CT along with significant changes in K max, pachy apex and ACV (p<0.036). HCL users had significantly higher K max stability (p<0.039). Conclusion: Regular use of appropriate therapeutic CLs may help to stabilize corneal deformity, thereby slowing changes in corneal topographic indices in KC.

Objective. Analysis of ophthalmological and musculoskeletal changes secondary to the use of electronic devices with digital screen, such as smartphones, laptops, computers or tablets. Material and Methods. This paper represents is a prospective observational study of 35 participants with ages between 6 and 17. The ophthalmological exam was carried out for all participants in the Ophthalmological Clinic of "Sf. Spiridon" Emergency Hospital, Iaşi, and the exam of musculoskeletal disorders took place at "Sf. Maria" Pediatrics Hospital, Iaşi. A questionnaire including 14 questions was also distributed for the symptoms caused by the use of digital screen electronic devices. Results. The mean age of participants was 11,29 ± 3,54 years, predominantly female children (62,9%). Convergence insufficiency has been identified in all patients with accommodative disorders and in 18.2% of the children with amblyopia (p = 0.001). The frequency of cases with dry eye syndrome (DES) was 9.1% in the patients with accommodative disorders and 18.2% in the patients with amblyopia. In the entire studied group of patients, the smartphone was the most frequently used electronic device, being found in 77.1% of the cases. As for the gender, about 54% of the boys spent more than 5 hours on electronic devices, while 54.5% of the girls spent between 3 to 5 hours. Among the symptoms that occur during the use of gadgets, pain in the neck, shoulders and back was found most often, being identified in 29 participants. Conclusion. Pre-existent ophthalmological symptoms can be exacerbated by prolonged use of digital screen electronic devices. Musculoskeletal symptoms were encountered in high numbers in all participants, which suggests that musculoskeletal changes must be treated with great importance in Computer Vision Syndrome. Also, the symptomatology determined by the use of gadgets was more frequently associated with males than females. Abbreviations: CVS = computer vision syndrome, VA = visual acuity, VDT= visual display terminals, DES = dry eye syndrome.

Glaucoma is one of important causes of irreversible vision loss and remains a global health problem. The pathophysiology of glaucoma involves several etiopathogenic mechanisms that have generated the development of topical and surgical treatments with an effect in slowing the progression of the disease. In the last decade, it was concluded that glaucomatous optic neuropathy is a disease with neurodegenerative elements, the destructive neuronal lesions being located not only in the structure of the retina, but also at the central visual pathways. This review highlights the experimental and clinical data obtained so far, which underline the neurodegenerative character of the glaucomatous disease and the elements of neuroconnectivity developed during the evolution of the disease.
