Impact of personal protective equipment on the clarity of vision among trachoma survey graders and trichiasis surgeons in the context of COVID-19

Background/aimsThe COVID-19 pandemic necessitated the use of personal protective equipment for those involved in trachoma survey grading and trichiasis surgery. We sought to determine which configuration of a face shield would be less likely to impact grading accuracy and ability to conduct trichiasis surgery. The research also included assessment of comfort, ease of cleaning and robustness.MethodsThere were three research phases. In phase 1, assessment of four potential face shield configurations was undertaken with principal trachoma graders and trichiasis surgeon trainers to decide which two options should undergo further testing. In phase 2, clarity of vision and comfort (in a classroom environment) of the two configurations were assessed compared with no face shield (control), while grading trachomatous inflammation—follicular (TF). The second phase also included the assessment of impact of the configurations while performing trichiasis surgery using a training model. In phase 3, face shield ease of use was evaluated during routine surgical programmes.ResultsIn phase 2, 124 trachoma graders and 28 trichiasis surgeons evaluated the 2 face shield configurations selected in phase 1. TF agreement was high (kappa=0.83 and 0.82) for both configurations compared with not wearing a face shield. Comfort was reported as good by 51% and 32% of graders using the two configurations. Trichiasis skill scores were similar for both configurations.ConclusionThe face shield configuration that includes a cut-out for mounting the 2.5× magnifying loupes does not appear to impact the ability or comfort of trachoma graders or trichiasis surgeons to carry out their work.

Remote ophthalmology with a smartphone adapter handled by nurses for the diagnosis of eye posterior pole pathologies during the COVID-19 pandemic.

Introduction: The use of smartphones to provide specialist ophthalmology services is becoming a more commonly used method to support patients with eye pathologies. During the COVID-19 pandemic, demand for telehealth services such as tele-ophthalmology, is increasing rapidly.Methods: In 2019, the agreement between diagnostic tests was investigated by comparing the diagnostic performance for eye posterior pole pathologies of the images obtained by a smartphone coupled to a medical device known as open retinoscope (OR), handled by a nurse and subsequently assessed by an ophthalmologist versus the images obtained by an ophthalmologist using a slit lamp associated to a 76 diopter indirect ophthalmic lens (Volk Super FieldVR ) (SL-IOL) at the outpatient department of a hospital. The OR used in this study worked with a 28 diopter indirect lens.Results: An examination of 151 dilated eyes (79 adult patients, mean age of 66.7 years, 59.5% women) was conducted. Sensitivity was 98.9%, specificity was 89.8%, the positive predictive value was 93.8% and the negative predictive value was 98.2%. The kappa index between both tests was 0.90 (95% CI: 0.83-0.97) in basic diagnosis, 0.81 (95% CI: 0.74-0.89) in syndromic diagnosis (13 categories) and 0.70 (95% CI: 0.62-0.77) in advanced diagnosis (23 categories).Discussion: Images obtained by a nurse using a smartphone coupled to the OR and subsequently assessed by an ophthalmologist showed a high diagnostic performance for eye posterior pole pathologies, which could pave the way for remote ophthalmology systems for this patient group.

Utilization of Instagram by Ophthalmology Residency Programs in the Era of COVID-19.

Purpose: The aim of this research is to describe the use of the social media platform, Instagram, by academic ophthalmology residency programs in the United States over time and consider the impact of the COVID-19 pandemic on ophthalmology's social media presence. Methods and Subjects: This cross-sectional study was conducted online by reviewing the publicly accessible Instagram accounts of all accredited US academic ophthalmology residency programs. Main Outcomes and Measures: Number of US ophthalmology residency programs with an affiliated Instagram account were analyzed by year of creation. The content of the top six accounts with the most followers was analyzed by evaluating amount of engagement within defined post categories. Results: Of the 124 ophthalmology residency programs, 78 (62.9%) were identified as having an affiliated Instagram account, 60 accounts (48.4%) were created during the years 2020 or 2021, and 62 (50.0%) accounts focused specifically on promoting the residency training program. Of the top six accounts with the most followers, post categories that received the most engagement were "Medical" and "Group Photo", while those that received the least engagement were "Department Bulletin" and "Miscellaneous." User engagement on posts as measured by likes and comments increased across multiple post categories after January 2020. Conclusion: Social media presence of ophthalmology residency programs on Instagram increased substantially in 2020 and 2021. As a result of the COVID-19 pandemic restricting in-person interactions, residency programs have used alternative platforms to reach applicants. Given the increasing use of such applications, social media will likely continue to become an important aspect of professional engagement in ophthalmology.

Specificities of pediatric ocular emergencies before and during the COVID-19 era: A retrospective comparative study in an eye-related emergency department in Paris.

INTRODUCTION: Epidemiological data on the use of eye-related emergency services by children are limited. The objective of this study was to determine how COVID-19 affected the epidemiological trends of pediatric ocular emergencies. METHODS: We performed a retrospective chart review of children under the age of 18 years who visited our eye-related emergency department between March 17 and June 7, 2020 and between March 18 and June 9, 2019. This was a descriptive and comparative analysis of the two study periods based on the demographic characteristics of patients and the diagnosis reported by the ophthalmologist in the digital medical charts. One of the investigators performed a second reading of the files to homogenize the diagnosis classification based on the most frequently found items. RESULTS: In total, 754 children were seen in our eye-related emergency department during the 2020 study period versus 1399 in 2019, representing a 46% decrease. In 2019, the four main diagnoses were traumatic injury (30%), allergic conjunctivitis (15%), infectious conjunctivitis (12%), and chalazion/blepharitis (12%). In the 2020 study period there was a significant decrease in the proportion of patients presenting with traumatic injuries (p < 0.001), infectious conjunctivitis (p = 0.03), and chalazion/blepharitis (p < 0.001). Consultations for chalazion/blepharitis were the most affected by the pandemic, followed by traumatic injuries (-72% and -64%, respectively). The proportion of patients who required surgery after trauma was higher in 2020 than in 2019 (p < 0.01), but the absolute number of severe trauma cases remained stable. CONCLUSIONS: The COVID-19 pandemic was accompanied by a decrease in the overall use of a pediatric eye-related emergency services in Paris. Visits due to benign causes and ocular trauma also decreased, but visits for more severe pathologies were not affected. Longer-term epidemiological studies may confirm or refute a change in eye emergency department use habits.

Impact of Postponement of Appointments on Vision and Psychological Well-Being Among Outpatients Attending Ophthalmology Clinics: A Malaysian Perspective.

INTRODUCTION: During the COVID-19 pandemic, non-frontline medical disciplines, including ophthalmology, were advised to minimize their services to channel crucial healthcare resources to manage the surge in COVID-19 cases. The ophthalmology department postponed all non-urgent appointments and elective surgical procedures. However, little is known about the visual and mental health impact of these changes in ophthalmology services. Therefore, our study aimed to explore the impact of postponement in ophthalmology outpatient clinic appointments towards visual acuity (VA) changes and the psychological well-being of patients during the COVID-19 pandemic in Malaysia. METHODOLOGY: This cross-sectional study, utilizing a convenience sampling method, recruited patients attending ophthalmology outpatient clinic services from July 2020 to June 2021 to participate in the study. The Snellen chart was used to measure the VA, and the Kessler psychological distress scale (K-10) was used to measure psychological distress levels among patients with (study) and without (controls) postponement of the appointment.  Results: A total of 485 patients were included in the data analysis; 267 study and 218 controls. There is a statistically significant difference in categorical change of VA (p < 0.001) and categorical K-10 score (p = 0.048) among the study and control groups. Nonetheless, a decline in VA alone does not show a statistically significant association with an increased probability of experiencing psychological distress (p=0.149). CONCLUSION: Postponement of ophthalmology appointments negatively affected the VA and the psychological well-being of patients. Appropriate assessment of patients before postponing their appointment is crucial to mitigate the worsening of VA and psychological distress.

Mental Wellbeing among Children with Cancer during COVID-19 Pandemic in Indonesia: A Cross-sectional Study

Introduction Coronavirus disease 2019 (COVID-19) has affected both physical and mental aspect of people worldwide, especially the high-risk group such as pediatric cancer patients. Children with cancer were considered both clinically and mentally vulnerable during this pandemic. They were also affected by the self- isolation, quarantine, and social distancing policy taken as a respond to public threat. Objectives To evaluate the impact of social distancing and health protocol during COVID-19 on the mental health profile of children with cancer in Indonesia. Methods A cross-sectional study evaluating the mental health of children with cancer during COVID-19 pandemic was conducted in Cipto Mangunkusumo Hospital, Jakarta, Indonesia from June to September 2020. An online questionnaire was used to collect demographics of parents and children, children's Strength and Difficulties Questionnaire ( SDQ) score, and parents' Self-Reporting Questionnaire (SRQ). SDQ score consists of five subscales, including the emotional symptoms, conduct problems, hyperactivity, peer relationships problems and prosocial behavior. Cancer types were grouped into retinoblastoma, nonretinoblastoma (other solid tumors), and leukemia. Results There were 156 valid responses, consisting of 42 patients with retinoblastoma, 34 patients with nonretinoblastoma ( other solid tumors), and 80 patients with leukemia. Pandemic-related lifestyle changes did not significantly impact emotional or behavioral problems. Children with normal total SDQ (odds ratio [OR]: 473, p = 0.001) and emotional scores (OR: 3.19, p = 0.07) had parents with normal SRQ scores (<6). Leukemia patients with shorter diagnosis period had worse hyperactivity score ( p = 0.01). On the contrary, leukemia inpatients had better prosocial scores than outpatients (p = 0.03). More bilateral retinoblastoma patients (p = 0.04) with longer duration of cancer diagnosis (p = 0.03) faced peer problems.

EyesOnMe: Investigating Haptic and Visual User Guidance for Near-Eye Positioning of Mobile Phones for Self-Eye-Examinations

The scarcity of professional ophthalmic equipment in rural areas and during exceptional situations such as the COVID-19 pandemic highlights the need for tele-ophthalmology. This late-breaking work presents a novel method for guiding users to a specific pose (3D position and 3D orientation) near the eye for mobile self-eye examinations using a smartphone. The user guidance is implemented utilizing haptic and visual modalities to guide the user and subsequently capture a close-up photo of the user's eyes. In a within-subject user study (n=24), the required time, success rate, and perceived demand for the visual and haptic feedback conditions were examined. The results indicate that haptic feedback was the most efficient and least cognitively demanding in the positioning task near the eye, whereas relying on only visual feedback can be more difficult due to the near focus point or refractive errors. © 2023 Owner/Author.

Navigating Giant Cell Arteritis (Gca) Service during and Post Covid-19 Pandemic: An Audit of Gca Care at North Bristol Nhs Trust against the Bsr Quality Standards

Background/Aims GCA is a systemic vasculitis predominantly affecting the large vessels that requires prompt diagnosis and management. This clinical audit aims to study the impacts of COVID-19 pandemic on our GCA service and to identify areas for improvement to ensure good and safe practice amid healthcare crisis. Methods We audited referrals for suspected GCA from February 2021 until September 2022 and measured our patient care against the BSR quality standards. We performed retrospective data collection from digital care record systems and analysed our data using the IBM SPSS Statistics version 29. Results 106 patients with suspected GCA were included, 73% were female and the mean age was 70 years. 75% of the referrals were from primary care. Main presenting symptoms were headaches (95.7%), scalp tenderness (69.6%), tongue/jaw claudication (52.2%), visual symptoms (47.8%), constitutional symptoms (43.5%) and polymyalgic symptoms (21.7%). 33% of patients were diagnosed and treated as GCA. Mean CRP was 23.9mg/L and mean plasma viscosity was 1.89mPA. The mean referral-to-specialist review time has reduced to 1.6 days, compared with 2.7 days pre-pandemic. All patients had vascular ultrasound but only 7.5% had a temporal artery biopsy (TAB), compared with 41% pre-pandemic. Table 1 compares expected and achieved BSR quality standards. Conclusion Changes in work pattern during the pandemic meant that the time from referral to specialist review was significantly reduced, by implementing twice weekly registrar-led 'Hot' clinics and reserving ad hoc slot(s) in on-call consultant's clinics for GCA referrals. We have ramped up our vascular imaging capacity for vascular ultrasound during the pandemic in response to reduced surgical operating capacity for TAB. Strategies to address areas for improvement identified in this audit include: (1) clear and timely communication with referrer about steroid initiation and dosage, at the time of referral;(2) improving communication with primary care, emphasising need for urgent Ophthalmology input in patients with suspected GCA-related visual symptoms, through updating our regional GCA guideline for primary care;(3) standardising and implementing a GCA review proforma or checklist in our department to ensure that the BSR GCA care bundle is being implemented and addressed at the earliest opportunity.

Ocular Oncology Practice During the COVID-19 Pandemic

The COVID-19 pandemic created a worldwide shift in how physician deliver optimal medical care. Ocular oncology practices have had to adapt to new challenges including how the delivery of service is performed in order to minimize SARS-CoV-2 exposure without sacrificing quality. Understanding the individual characteristics of every practice will maximize the efforts to adapt to this new reality. Telemedicine, virtual waiting rooms, and personal protective equipment have become the new standard during these unprecedented times. During clinic and operating room, our practices have had to strive for a new level of synchrony between patient and physician availability to minimize wasted time and exposure risk. Overall, medical care should not be delayed or deferred in patients with malignant ocular tumors during the COVID-19 pandemic;however, implementing safety measures for patients and healthcare workers is crucial to successfully continue to practice ocular oncology. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

A Case of Ocular Myasthenia Gravis Seen by Rheumatology as Suspected Mononeuritis Multiplex in an Adult Male Shortly after Pfizerbiontech Sars-Cov-2 Vaccination

Background/Aims Myasthenia gravis (MG) is an antibody-mediated autoimmune disease targeting proteins at the postsynaptic membrane of the neuromuscular junction. MG is thought to occur in genetically susceptible individuals following an environmental trigger. SARS-CoV-2 infection has been associated with new-onset autoimmune disease, new-onset MG, and exacerbations of pre-existing MG, with molecular mimicry between SARS-CoV-2 epitopes and autoantigen-induced autoreactivity thought to be part of the underlying mechanism. We report a case of newonset ocular MG following first dose Pfizer-BioNTech BNT162b2 SARS-COV2 vaccination which was referred to rheumatology as suspected mononeuritis multiplex. Methods A 53-year-old man of East Asian ethnicity presented to the emergency department (ED) with sudden onset diplopia and left lateral gaze restriction 7 days after receiving his first dose of the Pfizer-BioNTech BNT162b2 SARS-COV2 vaccination. He had longstanding myopia and dry eyes but no other medical history, no regular medications or significant family history. He was a current smoker, with a 50-pack year history. He did not drink alcohol or use any recreational drugs. He was found to have an isolated left VI cranial nerve (CN) palsy with an otherwise normal ocular and physical examination. Blood tests were unremarkable apart from raised cholesterol, and he was discharged with a suspected self-limiting microvascular CN lesion. Three weeks later he presented to ED with worsening diplopia, increasingly restricted eye movements, headache, nausea, vomiting and blurred vision. Ophthalmology assessment noted new right sided CN III and VI palsy, persistent left CN VI palsy, and vertical diplopia in all fields of gaze. Neurological and physical examination were normal. Bloods including an autoimmune screen were unremarkable. SARS-CoV-2 Spike antibodies were positive consistent with SARS-CoV-2 vaccination but not infection. Intracranial and thoracic imaging were unremarkable. He was referred to and seen by both rheumatology and neurology as a case of suspected mononeuritis multiplex. Results A diagnosis of ocular MG was confirmed with positive serum acetylcholine receptor antibodies, and he was started on prednisolone, and pyridostigmine to good effect. Daily forced vital capacity (FVC) showed no respiratory muscle involvement, and nerve conduction studies and electromyography were normal, excluding secondary generalisation. Conclusion A review of the literature found 14 reported cases of new-onset MG all within 4 weeks following SARS-CoV-2 vaccine. Whilst these cases provide interesting insights into the pathogenesis of autoimmune conditions such as MG, they are not epidemiological studies to inform vaccine safety. Ultimately, current evidence suggests that the risks of SARS-COV-2 infection outweigh the risk of vaccine-related adverse events, therefore we suggest clinicians should be aware of potential new-onset autoimmune conditions, but support the safety of SARSCOV2 vaccination. Further, research into possible immunological mechanisms behind this phenomenon, including identifying potential epitopes inducing molecular mimicry, could help establish the likelihood of a causative link.

Ophthalmic Manifestations Among Patients Surviving COVID-19.

Background and Aim: To identify ocular findings related to SARS-CoV-2 infection in patients after the resolution of COVID-19 using complete ocular examinations and optical coherence tomography (OCT). Methods: In this cross-sectional study, conducted from May 30 to October 30, 2020, patients who recovered from various stages COVID-19 underwent eye examination and multimodal retinal imaging (Retinographies and Spectral-OCT). Results: We included 50 patients, 29 (58%) males, median age of 46.5 [standard deviation 15.8]. Of these, 42% (21) had mild, 18% (9) had severe and 40% (20) had critical disease. The median time interquartile range (IQR) between symptom onset and ocular examination was 55 days [IQR 39-71]. Seven patients (14%) reported ophthalmic symptoms, transitory low visual acuity (6%) and retroocular pain (8%). On OCT, one patient without comorbidities had sectoral retinal pallor suggestive of acute retinal ischaemia and oedema of the retina's inner layers and atrophy. All findings progressively and spontaneously improved months after resolution of COVID-19. Conclusion: Patients with COVID-19 present findings compatible with the general population depending on age and comorbidities; nevertheless, acute retinal findings associated with the disease may be present, such as caused either by the direct effects of retinal SARS-CoV-2 infection, by indirect effects of the cytokine storm or by the pro-thrombotic state associated with COVID-19. Therefore, retinal involvement in patients with COVID-19 remains subject to considerable discussion and study.

Current situation and prospect of teleophthalmology.

With the development of technology, doctors can diagnose and treat many diseases through telemedicine. At present, teleophthalmology is mainly used in screening and diagnosing some ocular diseases, monitoring chronic ocular diseases, as well as teleconsultation. With the increasing demand and application of teleophthalmology, some problems will gradually become prominent, such as insufficient equipment and staff, medical risks, patient acceptance and satisfaction, network security, privacy, and covering of medical insurance. The global pandemic of COViD-19 has unexpectedly brought telemedicine to the forefront of ophthalmic services, and may continue to change the way of ophthalmic diagnosis and treatment. With the development of artificial intelligence technology, the expansion of 5G communication network coverage, the standardized training of primary medical staff, and the introduction of relevant laws and regulations, teleophthalmology will become more improved, universal, and widely applied, so as to provide patients with sustainable medical services of higher quality.Copyright © 2021, Peking Union Medical College Hospital.

Silent Thyroiditis as a Complication of Severe Acute Respiratory Syndrome Coronavirus 2 Vaccine

Introduction: Silent autoimmune thyroiditis, a type of chronic autoimmune thyroiditis, as an adverse effect of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is infrequently reported in the literature. We hereby describe a case of silent thyroiditis followed by Grave's orbitopathy after vaccination against SARS-CoV2. Case Description: An 84-year-old male presented to clinic with a 10-pound weight loss with no other symptoms of hyperthyroidism, no personal history of thyroid illnesses, or recent viral infections. He had normal thyroid function 3 months prior to presentation. He had received 3 doses of SARS-CoV2 Pfizer-BioNTech vaccine with the last dose 5 months prior to presentation. Thyroid exam was normal. Laboratory testing revealed thyroid stimulating hormone (TSH) level of 0.005 IU/ml (0.45-4.5 IU/ml), total T4 14.4 g/dl (4.5-12.1 g/dl), and total T3 1.22 nmol/l (0.6-1.81 nmol/l). Thyroid Ultrasound revealed a heterogeneous atrophic thyroid gland with no nodules or hypervascularity. He was started on Methimazole by primary care provider. Four months later, he was seen in the Endocrinology clinic and reported no hyperthyroidism symptoms. His TSH level at that time was 65.9 IU/ml, free T4 0.47 ng/dl (normal: 0.82-1.77 ng/dl), total T3 level 75 ng/dl (normal: 71-180 ng/dl), thyroid stimulating immunoglobulin 2.05 IU/l (0-0.55 IU/L), thyrotropin receptor antibody level 2.8 (0-1.75). Methimazole was discontinued. At 6 months after initial presentation laboratory testing showed TSH 5.010 IU/ml, free T4 1.2 ng/dl, thyroid peroxidase antibody of 148 IU/ml (normal 0-34 IU/ml), thyroglobulin antibody 131.6 IU/ml (normal 0.0-0.9 IU/ml). He was diagnosed with silent autoimmune thyroiditis. A few weeks later, the patient presented to an ophthalmologist with bilateral eye bulging and impaired vision. He was diagnosed with acute Graves' orbitopathy and started on pulse-dose of intravenous Methylprednisolone 250 mg twice daily and urgently referred to a tertiary ophthalmology center for teprotumumab infusion. His thyroid function tests were normal at that time on no thyroid medications. Discussion(s): The underlying mechanisms of thyroid impairment following SARS-CoV2 vaccination are not completely understood. There is a role of molecular mimicry between SARS-CoV2 antigens and thyroid antigens that may help to hasten the emergence of autoimmunity in vulnerable individuals. Our patient developed multiple thyroid-related antibodies following vaccination. Silent painless thyroiditis is a self-limiting condition, characterized by temporary thyrotoxicosis, followed by a brief period of hypothyroidism and then a complete return to normal thyroid function. A radioactive iodine uptake scan can help differentiate between the different causes of thyrotoxicosis in the acute thyrotoxic phase. Development of severe Graves orbitopathy following silent autoimmune thyroiditis after SARS COV2 vaccination has not been previously reported.Copyright © 2023

Ophthalmologist Turnover in the United States: Analysis of Workforce Changes from 2014 through 2021.

PURPOSE: Physician turnover is costly to health care systems and can affect patient experience due to discontinuity of care. This study aimed to assess the frequency of turnover by ophthalmologists and characteristics associated with turnover. DESIGN: A retrospective cross-sectional study. PARTICIPANTS: Actively practicing US ophthalmologists included in the Centers for Medicare & Medicaid Services (CMS) Physician Compare and Physician and Other Supplier Public Use File between 2014 and 2021. METHODS: Using two separate publicly available Medicare data sets, we collated data for ophthalmologists associated with practices in each year between 2014 and 2021. We calculated the rate of turnover as (1) annually in each year window and (2) cumulatively as the total proportion of 2014 practices separated by 2021. Multivariate logistic regression analysis was used to identify physician and practice characteristics associated with cumulative turnover. Additionally, we evaluated changes in annual turnover surrounding the Coronavirus disease 2019 pandemic. MAIN OUTCOME MEASURES: Ophthalmologist turnover, defined as a change of an ophthalmologist's National Provider Identifier practice affiliation from one year to the next. RESULTS: Of 13,264 ophthalmologists affiliated with 3,306 unique practices, 34.1% separated from at least one practice between 2014 and 2021. Annual turnover ranged from 3.7% (2017) to 19.4% (2018), with an average rate of 9.4%. Factors associated with increased turnover included solo practice (adjusted odds ratio [aOR], 9.59, p<0.01), university-affiliation (aOR, 1.55, p<0.01), practice location in the Northeast (aOR 1.39, p<0.01), and practice size of 2-4 members (aOR, 1.21, p<0.01). Factors associated with decreased turnover included male gender (aOR, 0.87, p<0.01), and greater than 5 years of practice: 6-10 years (aOR, 0.63), 11-19 years (aOR, 0.54), 20-29 years (aOR, 0.36), and ≥30 years (aOR, 0.18) (p < 0.01 for all). In the initial year of the COVID-19 pandemic (2020), annual turnover grew from 7.8% to 11.0%, then fell to 8.7% in the pandemic post-vaccine period (2021). CONCLUSIONS: One-third of US ophthalmologists separated from at least one practice from 2014-2021. Turnover patterns differ by various physician and practice characteristics, the knowledge of which may prove useful when developing strategies to optimize future workforce stability. Because reasons for turnover cannot be solely determined using administrative data, further investigation is warranted given the potential clinical and financial implications.

Visual complaints during the COVID-19 pandemic in Spain and Portugal.

PURPOSE: This study reports visual health during the COVID-19 pandemic in 2021 in Spain and Portugal, focusing on eye complaints and population habits. MATERIAL AND METHODS: Cross-sectional survey through an online email invitation to patients attending ophthalmology clinics in Spain and Portugal from September to November 2021. Around 3833 participants offered valid anonymous responses in a questionnaire. RESULTS: Sixty percent of respondents identified significant discomfort related to dry eye symptoms for increased screen time and lens fogging using facemasks. 81.6% of the participants used digital devices for more than 3 h per day and 40% for more than 8 h. In addition, 44% of participants referred to worsening near vision. The most frequent ametropias were myopia (40.2%) and astigmatism (36.7%). Parents considered eyesight the most important aspect of their children (87.2%). CONCLUSIONS: The results show the challenges for eye practices during the initial COVID-19 pandemic. Focusing on signs and symptoms that lead to ophthalmologic conditions is an essential concern, especially in our digital society highly dependent on vision. At the same time, the excessive use of digital devices during this pandemic has aggravated dry eye and myopia.

Role of Recent PCR Tests for Infectious Ocular Diseases: From Laboratory-Based Studies to the Clinic.

Infectious uveitis is a vision-threatening condition that requires prompt clinical diagnosis and proper treatment. However, rapid and proper diagnosis in infectious uveitis remains challenging. Several examination tests, including polymerase chain reaction (PCR) tests, are transitioning from laboratory-based basic research-level tests to bedside clinical tests, and recently tests have changed to where they can be performed right next to clinicians. In this review, we introduce an updated overview of recent studies that are representative of the current trends in clinical microbiological techniques including PCR tests for infectious uveitis.

COVID-19-related Conjunctivitis Review: Clinical Features and Management.

PURPOSE: The ongoing coronavirus disease-2019 (COVID-19) pandemic has greatly impacted theworld. In this review article, we discuss the conjunctival and nasolacrimal mucosa as a potential route for the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) transmission, its ocular manifestations, and management. METHODS: Literature review was conducted in the PubMed, Google Scholar and EMBASE databases using keywords such as "coronavirus", COVID-19", "SARS-CoV-2", "conjunctivitis", "ocular surface", "eye" and "ophthalmology". RESULTS: The ocular surface may serve as an entry point and reservoir for the virus. Frequency of hand-eye contact was an independent risk factor for COVID-19-related conjunctivitis. Therefore, appropriate protective eyewear or face shields are recommended, especially for health-care workers. Bilateral conjunctival sampling within 9 days of symptom onset provides a higher positive yield rate. Pooled analysis shows an incidence of 11.4% (95%CI = 6.4-17.2%) of ocular manifestations in patients with SARS-CoV-2 infection, including hospitalized and non-hospitalized patients. CONCLUSION: Conjunctivitis was the most common ocular manifestation, of which ocular redness or congestion, ocular pain, and follicular conjunctivitis were the most common presentation.COVID-19-related conjunctivitis has a self-limiting disease course, and treatment should be mainly supportive.
