Purpose: To summarize COVID-19 research endeavors by ophthalmologists/researchers in terms of publication numbers, journals and author countries, and to detail key findings. Methods: The LitCovid database was systematically reviewed for ophthalmology-focused COVID-19 articles. The quality of the evidence was assessed for articles investigating conjunctivitis in COVID-19 patients. Results: There were 21,364 articles in LitCovid on June 12, 2020, of which 215 (1%) were ophthalmology-focused. Of articles on COVID-19 transmission, 3.3% were ophthalmology-focused. Ophthalmology-focused articles were published in 68 journals and originated from 25 countries. The top five countries publishing ophthalmology-focused articles (China, India, United States of America, Italy, and United Kingdom) produced 145/215 (67%) articles. A total of 16 case reports/series from eight countries reported that conjunctivitis can be the initial or the only symptom of COVID-19 infection. Conjunctivitis may occur in the middle phase of COVID-19 illness. A total of 10 hospital-based cross-sectional studies reported that between 0% and 31.6% of COVID-19 patients have conjunctivitis or other ocular conditions, with a pooled prevalence of 5.5% reported in a meta-analysis. Viral RNA was detected in conjunctival swabs of patients with and without ocular manifestations, after resolution of conjunctivitis, after nasopharyngeal swabs turned negative and in retina of deceased COVID-19 patients. Conclusion: Within 3 months of declaring the COVID-19 pandemic, 215 ophthalmology-focused articles were published in PubMed, concentrating on disease manifestations and transmission. The reported presence of conjunctivitis or other ocular conditions in COVID-19 patients is varied. Clinicians should be alert for ocular involvement in COVID-19 infections and possible ocular transmission even in patients without ocular symptoms.

Meta Analyses

Several studies have reported the characteristics of Coronavirus disease 2019 (COVID-19), yet there is a gap in our understanding of the ocular manifestations of COVID-19. In this systematic review and meta-analysis, we investigated the prevalence of ocular manifestations in COVID-19 patients. We searched Pubmed, Embase, Scopus, Web of Science, and medRxiv from December 1, 2019 to August 11, 2020. Two independent reviewers screened the articles, abstracted the data, and assessed the quality of included studies in duplicate. Thirty-eight studies were eligible after screening of 895 unique articles, with a total of 8,219 COVID-19 patients (55.3% female; n = 3,486 out of 6,308 patients). Using data extracted from cross-sectional studies, we performed randomeffects meta-analyses to estimate the pooled prevalence of ocular symptoms along with 95% confidence interval (CI). The prevalence of ocular manifestations was estimated to be 11.03% (95% CI: 5.71–17.72). In the studies that reported the details of observed ocular symptoms, the most common ocular manifestations were dry eye or foreign body sensation (n = 138, 16%), redness (n = 114, 13.3%), tearing (n = 111, 12.8%), itching (n = 109, 12.6%), eye pain (n = 83, 9.6%) and discharge (n = 76, 8.8%). Moreover, conjunctivitis had the highest rate among reported ocular diseases in COVID-19 patients (79 out of 89, 88.8%). The results suggest that approximately one out of ten COVID-19 patients show at least one ocular symptom. Attention to ocular manifestations, especially conjunctivitis, can increase the sensitivity of COVID-19 detection among patients.

AbstractObjectiveTo estimate the prevalence of ocular manifestations and ocular samples polymerase chain reaction (PCR) positivity among COVID-19 patients.MethodsA systematic literature review was performed using search engines (PubMed, Google Scholar, Medrixv and BioRixv) with keywords “SARS-CoV-2”, “novel coronavirus”, “COVID-19”, “ocular manifestations”, “conjunctival congestion”, “Ocular detection”, “Polymerase chain reaction”, and “conjunctivitis”. The measure of heterogeneity was evaluated with the I2 statistic. The pooled proportion of patients presenting with symptoms and ocular samples PCR positivity was estimated.ResultsA total of 20 studies (14 studies and 6 case-reports) were included in the systematic review and 14 studies were included in the meta-analysis. The pooled prevalence of conjunctivitis was 5.17% (95% CI: 2.90-8.04). Conjunctivitis was reported as an initial symptom of the disease in 0.858 % (95% CI: 0.31-1.67). Common associated features include itching, chemosis, epiphora. Seven patients (29 %) with conjunctivitis showed positive results in ocular samples, whereas 13 patients (54%) showed positive only in their nasopharyngeal samples (NPs) or sputum samples and 4 patients (16 %) were negative for both NPs and Sputum as well as ocular samples. The pooled prevalence of ocular PCR positivity was 2.90 % (95% CI: 1.77 – 4.46) vs. NPs 89.8% (95% CI: 78.80-79.0).ConclusionThe prevalence of conjunctivitis and ocular samples PCR positivity among COVID-19 patients was low indicating that the eye is a less affected organ. However, conjunctivitis may present as the first symptom of the disease making the patient seek medical care at the earliest.SynopsisViral conjunctivitis was the only symptom reported. The prevalence of conjunctivitis and ocular samples polymerase chain reaction positivity among COVID-19 patients was low indicating the eye is a less effected organ.

Abstract Importance: The first systematic review and meta-analysis to help clinician to identify early the sign and symptoms of neurological manifestation in COVID-19 positive patients which further help in early management of patients. Objective: Present systematic review and meta-analysis aimed to discuss the prevalence of neurological involvement of the 2019-nCoV patients and assess the symptomatic trend of events as compared to the 2002 “SARS” and 2012 “MERS” pandemics.Methods: The articles were systematically screened through several search engine and databases. The articles published or in preprint were included in the study till 15th May 2020. The systematic review done as per the published literatures which included 31 cross sectional, observational studies and case reports which revealed neural sign and symptoms in SARS-COV-2 disease. For meta-analysis, we included 09 observational and cross sectional studies which included COVID-19 positive patients and assessed the predominance of various neurological sign and symptoms in COVID-19 patients relation to SARS-2002 and MERS-2012. Data were analyzed by using the “MedCalc Statistical Software version 19.2.6 and reported as pooled prevalence. Heterogeneity was investigated (standard I2 test). Results: We have collected and screened about a total 2615 articles, finally we have included 31 articles for the systematic review and 09 for meta-analysis as per the inclusion/exclusion criteria. The analysis was made as per the prevalence rate of neurological symptoms during the COVID-19 positive patients. The cumulative neurological outcome of SARS-2002 and MERS-2012 was assessed to get the trends which is next tried to correlate the events with the current pandemic. During the analysis severity and outcome of neurological manifestations range from simple headache to vague non-focal complaints to severe neurologic impairment associated with seizure or meningitis.Conclusion & Relevance: Central and peripheral nervous system (CNS/PNS) manifestations were seen during the SARS-2002, MERS-2012 and COVID-19. However, none of the publication found with the primary or secondary objective of finding the neurological manifestation in the COVID-19 patients and their mechanism which strengthen the importance to start more precise clinical trials.

Objective There is a broad spectrum of eye involvement in antiphospholipid syndrome (APS). The majority of descriptions are presented as case reports that include mostly APS patients secondary to systemic lupus erythematosus (SLE), with no compelling evidence in primary APS (PAPS). This study aimed to describe ocular manifestations in our well-defined PAPS cohort (APS-Rio) and then perform a systematic literature review (SLR) of ocular manifestations in patients with APS or positivity to aPL without SLE. Methods We retrospectively analyzed PAPS patients followed at our outpatient clinics. All patients fulfilled Sydney APS classification criteria (2006). We evaluated them for ocular symptoms and previous ocular diagnoses. Antiphospholipid antibodies and clinical APS manifestations were compared between patients with and without ocular manifestations. For the SLR, electronic databases were searched up to November 2019. Results We studied 105 PAPS patients; 90.5% were female and 56.2% were Caucasian. We found ocular manifestations in 37.1% of our cohort. Thrombosis was the main criteria manifestation (95.2%) and lupus anticoagulant was the most prevalent antibody. Ophthalmologic diagnoses were present in 7 patients, with 5 having retinal vessels thromboses. Amaurosis fugax was the leading complaint, present in 30 patients. In the univariate analysis, amaurosis fugax was related to livedo (p = 0.005), Raynaud’s phenomenon (p = 0.048) and the presence of anticardiolipin antibody (≥40 GPL/MPL) (p = 0.041). Hemianopia was associated with arterial hypertension (p = 0.049). In the multivariate analysis, the only association found was between livedo and amaurosis fugax (OR 4.09, 95%CI 1.5–11.11, p = 0.006). Our SLR incorporated 96 articles of ocular manifestations in patients with PAPS or positivity to aPL without SLE. Ocular findings varied from 5 to 88%, including anterior and posterior segments, orbital and neuro-ophthalmologic changes. Conclusion There is little evidence on ocular manifestations in PAPS. We described an association between livedo and amaurosis fugax. Prospective studies are needed to promote the best treatment and avoid blindness in PAPS patients.

The coronavirus disease 2019 (COVID-19) pandemic has had profound and lasting consequences since 2019. Although vaccines against COVID-19 have been developed and approved under emergency use authorization, various adverse events have also been reported after COVID-19 vaccination. This review was undertaken to help clinicians recognize the possible manifestations and systemic pathogenesis, especially those related to the eye, after receiving COVID-19 vaccination. A systemic search was performed on 22 August 2021 through Embase, Medline, and Cochrane Library for publications on ocular manifestations after COVID-19 vaccination. Two case-control studies/retrospective cohort studies, one cross-sectional study, three case series, sixteen case reports, two images, and seven letters were included. Ocular manifestations after receiving COVID-19 vaccines may appear on the eyelid, cornea and ocular surface, retina, uvea, nerve, and vessel. The ocular manifestations occurred up to forty-two days after vaccination, and vaccine-induced immunologic responses may be responsible. Although the incidence rate of ocular symptoms is considerably lower in the vaccinated subjects than in COVID-19 patients, physicians should be aware of the possible associations between COVID-19 vaccines and ocular symptoms for the early diagnosis and treatment of vision problems or life-threatening complications.

Purpose This study was performed to determine the occurrence of ocular surface manifestations in patients diagnosed with coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods A systematic search of electronic databases i.e. PubMed, Web of Science, CINAHL, OVID and Google scholar was performed using a comprehensive search strategy. The searches were current through 31st May 2020. Pooled data from cross-sectional studies was used for meta-analysis and a narrative synthesis was conducted for studies where a meta-analysis was not feasible. Results A total of 16 studies reporting 2347 confirmed COVID-19 cases were included. Pooled data showed that 11.64% of COVID-19 patients had ocular surface manifestations. Ocular pain (31.2%), discharge (19.2%), redness (10.8%), and follicular conjunctivitis (7.7%) were the main features. 6.9% patients with ocular manifestations had severe pneumonia. Viral RNA was detected from the ocular specimens in 3.5% patients. Conclusion The most common reported ocular presentations of COVID-19 included ocular pain, redness, discharge, and follicular conjunctivitis. A small proportion of patients had viral RNA in their conjunctival/tear samples. The available studies show significant publication bias and heterogeneity. Prospective studies with methodical collection and data reporting are needed for evaluation of ocular involvement in COVID-19.

Multiple recurrent somatic mutations have recently been identified in association with myeloproliferative neoplasms (MPN). This meta-analysis aims to assess the pooled prevalence of TET2 gene mutations among patients with MPN. Six databases (PubMed, Scopus, ScienceDirect, Google Scholar, Web of Science and Embase) were searched for relevant studies from inception till September 2020, without language restrictions. The eligibility criteria included BCR-ABL-negative MPN adults with TET2 gene mutations. A random-effects model was used to estimate the pooled prevalence with 95% confidence intervals (CIs). Subgroup analyses explored results among different continents and countries, WHO diagnostic criteria, screening methods and types of MF. Quality assessment was undertaken using the Joanna Briggs Institute critical appraisal tool. The study was registered with PROSPERO (CRD42020212223). Thirty-five studies were included (n = 5121, 47.1% female). Overall, the pooled prevalence of TET2 gene mutations in MPN patients was 15.5% (95% CI: 12.1–19.0%, I2 = 94%). Regional differences explained a substantial amount of heterogeneity. The prevalence of TET2 gene mutations among the three subtypes PV, ET and MF were 16.8%, 9.8% and 15.7%, respectively. The quality of the included studies was determined to be moderate–high among 83% of the included studies. Among patients with BCR-ABL-negative MPN, the overall prevalence of TET2 gene mutations was 15.5%.

Background: There is evidence of a high psychological toll from the COVID-19 pandemic in healthcare workers. This paper was aimed at conducting a systematic review and meta-analysis of studies reporting levels of depression among healthcare workers during the COVID-19 and estimating the pooled prevalence of depression. Methods: We searched for cross-sectional studies listed on PubMed from 1 December 2019 to 15 September 2020 that reported prevalence of depression in healthcare workers, nurses, medical doctors, and COVID-19 frontline professionals. The pooled proportions of depression were calculated with random effects models. Results: We identified 57 studies from seventeen countries. The pooled prevalence of depression in healthcare workers was 24% (95% CI: 20%−28%), 25% for nurses (95% CI: 18%−33%), 24% for medical doctors (95% CI: 16%−31%), and 43% for frontline professionals (95% CI: 28%−59%). Conclusions: The proportion of depression in nurses and medical doctors during the COVID-19 pandemic was similar to that found in the general population as previously reported in other meta-analyses conducted with smaller numbers of studies. Importantly, almost half of the frontline healthcare workers showed increased levels of depression. There is need for a comprehensive, international response to prevent and treat common mental health problems in healthcare workers.

IntroductionIndividuals living in poor neighbourhoods are at a higher risk of overweight/obesity. There is no systematic review and meta-analysis study on the association of neighbourhood socioeconomic status (NSES) with overweight/obesity. We aimed to systematically review and meta-analyse the existing evidence on the association of NSES with overweight/obesity.Methods and analysisCross-sectional, case–control and cohort studies published in English from inception to 15 May 2017 will be systematically searched using the following databases: PubMed, EMBASE, Web of Sciences and Google Scholar. Selection, screening, reviewing and data extraction will be done by two reviewers, independently and in duplicate. The Newcastle–Ottawa Scale (NOS) will be used to assess the quality of evidence. Publication bias will be checked by visual inspection of funnel plots and Egger’s regression test. Heterogeneity will be checked by Higgins’s method (I2statistics). Meta-analysis will be done to estimate the pooled OR. Narrative synthesis will be performed if meta-analysis is not feasible due to high heterogeneity of studies.Ethics and disseminationEthical clearance is not required as we will be using data from published articles. Findings will be communicated through a publication in a peer-reviewed journal and presentations at professional conferences.PROSPERO registration numberCRD42017063889.

Background: Ocular complications of herpes zoster ophthalmicus (HZO) may lead to substantial visual disability, severe post-herpetic neuralgia and rarely fatal cerebral complications. Aim: To identify the pattern of ocular manifestation in herpes zoster ophthalmicus. Materials and methods: A cross-sectional descriptive study was under taken including the clinically diagnosed cases of HZO. All of them underwent a complete ophthalmological evaluation. Results: Sixty-eight cases of HZO were examined, of which 37 (54.4 %) were male and 31 (45.6%) female. The mean age was 48.7 ± 18.5 years. Most of the patients (64.7 %) were above the age of 40 years. 77.94 % of the patients had some form of ocular involvement. Pain (77.9 %) was the commonest ocular complaint. In young patients less than 35 years, HIV was the most common risk factor (19.3 %).Visual status was good in the majority (73.5 %) of patients at presentation. Lid and adnexal findings (45.8 %) were most common ocular involvement followed by conjunctivitis (41.1 %). Corneal complication was seen in 38.2 % of cases, uveitis in 19.1 % and post-herpetic neuralgia (PHN) and secondary glaucoma each in 5.8 %. Conclusion: Eyelid and ocular adnexal involvement is most commonly found in patients with herpes zoster ophthalmicus followed by corneal complication and uveitis. There needs to be awareness of ocular involvement, which can be sight threatening, among the HZO patients and other medical departments and an increased emphasis on regular ophthalmic examination.
