Conducting online classes on a national scale is a herculean task for a developing country because of poor internet connectivity and deficient access to high-speed broadband services. Nevertheless, their popularity among students during the current crisis shows that it is a very pragmatic and feasible teaching option and can definitely supplement traditional classroom teaching.
With the outbreak of coronavirus disease 2019 (COVID-19), India went for lockdown-I on March 23, 2020. In this article, we report on the demographic profile and ocular disorders from our 20 rural eye centres during lockdown-I and its comparison with the pre-lockdown period.

A retrospective analysis was conducted for all patients who visited or had teleconsultations at the 20 rural centres in our network between March 23 and April 19, 2020. #link# Demographic and clinical details were collected from electronic medical records (EMR). Subspecialty was decided based on the diagnosis. Patients who needed advanced care were referred to the higher tertiary centres. We report the profile of patients seen and managed at the rural centres and the reasons for referrals. We also compare the data with the pre-lockdown period.

During the lockdown-I period, a total of 263 patients were treated including 48 teleconsultations (18.25%). The mean age was 48.16 years (SD 19.53 years). There were 118 females (44.87%). As compared to the pre-lockdown period, during the lockdown, there was an issue with access to services by females. Despite a higher number of specialty patients (including emergencies) visiting during the lockdown, 91% of the patients who visited rural centres could be managed locally, avoiding long-distance travel.
To evaluate the impact of 2019 COVID-19 pandemic, national lockdown, and unlocking on ophthalmic care provided by the government-funded apex health institute of India.

Retrospective review of electronic medical records of all patients presenting to the ophthalmology department from March 23, 2020, to July 15, 2020, was compared with that from March 23, 2019, to July 15, 2019. The data between March 23, 2020, to May 31, 2020 (lockdown) and June 06, 2020, to July 15, 2020 (unlock) was compared separately. Parameters evaluated were age, gender, presenting complaints, final diagnosis, treatment advised, and surgical interventions.

During the lockdown, routine outpatient flow reduced by 97.14% (P < 0.001), the median age of presentation decreased to 29 years (55 years last year) and males increased by 4.7% (from 61.51% to 66.21%) in 2020. Emergency services decreased by 35.25%, percentage of children decreased by 4.28% (from 34.28% to 30%) and males increased by 13.53% (from 59.97% to 73.5%). link2 Mechanical t by the apex-ophthalmic institute. Unlike anticipated, lifting of pandemic-associated lockdown served only minimally in improving patient inflow in its initial phases.
The aim of this study was to assess the knowledge, attitude, and practice (KAP) pattern towards COVID-19, among patients presenting to eye care hospitals during the last phase of lockdown period.

A multicenter cross-sectional survey was conducted from May 15 to June 15, 2020 in five tertiary eye care hospitals in South India to assess the KAP towards COVID-19. Each of the hospitals belonged to one of the three different zones assigned in India based on number of infections. Red zones represent hotspots and orange/green zones represent regions with medium and lower caseloads, respectively. A validated questionnaire was administered through telephone and responses were recorded on a Google form.

Out of the total (n = 6119) participants, 3081 were from hospitals in green zone, 2110 from the orange zone, and 928 from red zone. Majority of participants were above 50 years of age (42%) and 15.54% were illiterate. link3 The mean (percentage) scores of knowledge, attitude, and practice were 21.26 (82%), 9.37 (92%), and 10.32 (86%), respectively. KAP among patients more than 50 years of age and in illiterate individuals was significantly less (P < 0.01) when compared with all other groups. Participants from red zone had a significantly better attitude (P < 0.01) compared to other centers.

Although the overall KAP regarding COVID-19 disease was robust (above 80% in all categories) in our participants, the high risk elderly population (>50 years) and illiterate individuals had a significantly lower KAP. These are populations in which education should be emphasized and appropriately delivered as a way to reduce COVID-19 risk.

Since the declaration of the lockdown due to COVID-19, the usage of digital devices has gone up across the globe, resulting in a challenge for the visual systems of all ages. The purpose of this study is to assess the impact of the lockdown on digital device usage, and consequently, the ocular surface health implications and circadian rhythm abnormalities related to digital eye strain.

An open online survey was sent through various social media platforms and was open for a period of 2 weeks.

A total of 407 usable responses were obtained; the average age of respondents was 27.4 years. Typically, 93.6% of respondents reported an increase in their screen time since the lockdown was declared. The average increase in digital device usage was calculated at about 4.8 ± 2.8 h per day. The total usage per day was found to be 8.65 ± 3.74 hours. Sleep disturbances have been reported by 62.4% of people. Typically, 95.8% of respondents had experienced at least one symptom related to digital device usage, and 56.5% said that the frequency and intensity of these symptoms increased since the lockdown was declared.

The study highlighted the drastic increase in use of digital devices after the initiation of the COVID-19 lockdown, and along with it, the slow deterioration of ocular health across all age groups. Awareness about prevention of digital eye strain should be stressed, and going forward, measures to bring these adverse effects to a minimum should be explored.

To study the prevalence of asymptomatic SARS-CoV-2 virus infection (COVID-19) among patients undergoing elective vitreoretinal surgeries at a tertiary care eye hospital.

This cross-sectional, observational study was performed between July 16, 2020 and August 31, 2020, in the retina clinic of a tertiary care eye hospital in south India. All patients undergoing elective retinal surgical procedures underwent RT-PCR testing for SARS-CoV-2 before being posted for surgery and after obtaining informed consent. Patients planned for surgery under general anesthesia underwent additional computed tomography of the chest. Testing strategies and outcomes were documented.

Out of a total of 413 patients who were given appointments for surgery during this period, nine patients (2.2%) were found to have positive RT-PCR for SARS-CoV-2, and their surgeries were postponed. The test positivity (prevalence) rate of asymptomatic COVID-19 infection among all elective vitreoretinal surgical patients in our hospital was 2.2%. None of the patients were symptomatic for COVID-19.

Our results showed that among patients visiting high volume ophthalmic centers in the near future, approximately 1 in 45 patients may be asymptomatic, SARS-CoV-2 RT-PCR positive. this website -19 patients may lead to chances of transmission of the virus inside healthcare facilities among other visiting patients and healthcare workers.

The purpose of this study was to discuss the guidelines and modification of practices with respect to corneal transplantation and eye banking during the COVID-19 pandemic lockdown period and beyond, at a network of tertiary care centers in India.

Descriptive study of the challenges faced in eye banking during the lockdown, and practices adopted to overcome the critical aspects in the clinical care of patients who presented with emergency corneal diseases requiring keratoplasty.

Complete lockdown orders from the Indian government, as a strategy to control the Coronavirus pandemic, resulted in drastic reduction of all types of elective corneal transplants and eye banking activities from March 24, 2020 to May 31, 2020. The sudden cessation of eye banking resulted in an acute demand and supply imbalance of fresh donor corneas for transplants during this time. Our network of eye banks addressed this issue by adopting glycerol preservation of donor corneas, which were subsequently utilized for tectonic penetrating keratoplasty. The donor cornea retrieval was resumed in a strategized manner 3 weeks prior to the date of exit of the lockdown, with modified guidelines on donor suitability, screening, retrieval, processing, and harvesting from various sources. A triage of keratoplasty priority was formulated to tide over the post lockdown shortage of corneas. We performed 31 therapeutic keratoplasties during the nationwide lockdown among our network of tertiary eye care centers.

The study highlights the approach and strategies to manage and tide over an unprecedented crisis situation faced by corneal surgeons in general and, specifically, the eye banking community.
