AbstractKnobloch syndrome (KS) is an autosomal recessive disorder caused by biallelic pathogenic variants in COL18A1. KS clinically manifests with the typical eye findings (high myopia, vitreoretinal degeneration, retinal detachment, and lens subluxation), variable neurological findings (occipital encephalocele, polymicrogyria, cerebellar malformations, epilepsy, and intellectual disability), and the other uncommon clinical manifestations. Literature review of all KS patients (source PubMed) was done with special reference to cerebellar abnormalities. Here, we report two siblings with typical KS with posterior fossa malformations and novel cerebellar midline cleft abnormality analyzed by whole exome sequencing. Known pathogenic homozygous variant c.2908C > T; (p.Arg970Ter) in exon 26 of COL18A1 was found as a cause for KS. These two siblings presented with early-onset severe ocular manifestations, facial dysmorphism, and variable central nervous system manifestations along with novel cerebellar midline cleft abnormality. The presence or absence of structural brain malformations and genotypes does not absolutely predict cognitive functions in KS patients. However, the presence of posterior fossa abnormality may be predictive for the development of ataxia in later life and needs further studies.

Background: Zika virus infection during pregnancy has been recently associated with congenital microcephaly and other severe neural tube defects. However, the magnitude of confirmed cases and the scope of these anomalies have not been extensively documented. This review focuses on the magnitude of laboratory-confirmed congenital Zika virus cases among probable cases and describing the patterns of congenital anomalies allegedly caused by the Zika virus, information which will inform further research in this area. Methods: We conducted a literature search for English-language articles about congenital Zika virus infection using online electronic databases (PubMed/MEDLINE, POPLINE, Embase, Google Scholar, and Web of Knowledge). The search terms used were, “zika”, “pregnancy”, [year], “microcephaly”, “infants”, “children”, “neonates”, “foetuses”, “neural tube defect”, and “CNS manifestations” in different combinations. All articles reporting cases or case series between January 2015 and December 2016 were included. Data were entered into a Microsoft Excel database and analysed to obtain proportions of the confirmed cases and patterns of anomalies. Results: A total of 24 articles (11 case series, 9 case reports, and 4 others) were found to be eligible and included in this review. These articles reported 919 cases, with or without microcephaly, presumed to have congenital Zika virus infection. Of these cases, 884 (96.2%) had microcephaly. Of the 884 cases of microcephaly, 783 (88.6%) were tested for Zika virus infection, and 216 (27.6%; 95% confidence interval, 24.5% to 30.8%) were confirmed to be Zika virus-positive. In addition to microcephaly, other common abnormalities reported – out of 442 cases investigated – were calcifications of brain tissue (n=240, 54.3%), ventriculomegaly (n=93, 20.8%), cerebellar hypoplasia (n=52, 11.7%), and ocular manifestations (n=46, 10.4%). Conclusion: Based on the available literature, Zika virus infection during pregnancy might lead to a wide array of outcomes other than microcephaly. There is a need for more epidemiological studies in Zika-endemic areas, particularly in Africa, to ascertain the role of Zika virus in causing congenital neurological defects.

This is a brief review covering the currently available literature on ocular manifestations of COVID-19, andprevention strategies for ophthalmologists. A literature search was carried out of Pubmed, Google Scholar andWHO database of publications on COVID. Keywords used in the search were eye, ocular manifestations,ophthalmology, COVID-19, nCoV-2019, and coronavirus disease. All available articles were reviewed and thosepertinent to the study topic were included. Considering the dearth of information available, ophthalmology journals were also searched separately for relevant articles. Major ocular manifestation of COVID reported in literature is red eye, which usually presents before the onset of respiratory symptoms. Since the eye can be a possible transmission route for SARS-CoV-2, infection control measures should be undertaken by ophthalmologists, including use of personal protection equipment and eye/face covering. A framework for structuring ophthalmological services during the COVID pandemic is also presented in this review.

Emerging Viral Diseases

AbstractEmerging infectious diseases (EIDs) are an increasing threat to public health on a global scale. In recent times, the most prominent outbreaks have constituted RNA viruses, spreading via droplets (COVID-19 and Influenza A H1N1), directly between humans (Ebola and Marburg), via arthropod vectors (Dengue, Zika, West Nile, Chikungunya, Crimean Congo) and zoonotically (Lassa fever, Nipah, Rift Valley fever, Hantaviruses). However, specific approved antiviral therapies and vaccine availability are scarce, and public health measures remain critical. Patients can present with a spectrum of ocular manifestations. Emerging infectious diseases should therefore be considered in the differential diagnosis of ocular inflammatory conditions in patients inhabiting or returning from endemic territories, and more general vigilance is advisable in the context of a global pandemic. Eye specialists are in a position to facilitate swift diagnosis, improve clinical outcomes, and contribute to wider public health efforts during outbreaks. This article reviews those emerging viral diseases associated with reports of ocular manifestations and summarizes details pertinent to practicing eye specialists.

Low Prevalence

Abstract Background Manitoba-oculo-tricho-anal (MOTA) syndrome is a rare syndrome with only 27 cases reported worldwide so far, but none was reported in the population of Eastern Asia. Such extremely low prevalence might be contributed by misdiagnosis due to its similarities in ocular manifestations with facial cleft. In our study, we discovered the first case of MOTA syndrome in the population of China, with 2 novel FRAS1 related extracellular matrix 1 (FREM1) gene stop-gain mutations confirmed by whole exome sequencing. Case presentation A 12-year-old Chinese girl presented with facial cleft-like deformities including aberrant hairline, blepharon-coloboma and broad bifid nose since birth. Whole exome sequencing resulted in the identification of 2 novel stop-gain mutations in the FREM1 gene. Diagnosis of MOTA syndrome was then established. Conclusions We discovered the first sporadic case of MOTA syndrome according to clinical manifestations and genetic etiology in the Chinese population. We have identified 2 novel stop-gain mutations in FREM1 gene which further expands the spectrum of mutational seen in the MOTA syndrome. Further research should be conducted for better understanding of its mechanism, establishment of an accurate diagnosis, and eventually the exploitation of a more effective and comprehensive therapeutic intervention for MOTA syndrome.

Abstract Introduction Corona virus disease (COVID-19) pandemic can cause myriad of ocular manifestations. We report a case of unilateral multi focal central serous retinopathy, post COVID-19 infection in an Asian Indian female. Case presentation A 42-year-old female presented to us with unilateral blurring, in the right eye (OD), 12 days after COVID-19 infection. She had fever, chills, shortness of breath and cough with tiredness and was COVID- RT PCR positive. She was administered intravenous and oral antibiotics with injection heparin/remdesivir, during her 7 day stay at the hospital. She was also on steroid inhalers. She had no systemic history of note. On ocular evaluation, her corrected distance visual acuity was 20/40 in OD and 20/20 in left eye (OS). Anterior segment was normal. Anterior vitreous was clear. Fundus examination of the OD showed central serous retinopathy (CSCR) with OS being normal. Conclusion CSCR can occur post COVID-19 due to steroid administration and physicians administering it should be aware of this and refer the patients to an ophthalmologist earlier.
