The mean PHQ-9 score was 3.98 (range, 0-27; SD, 4.65). In terms of psychological impact, 768 (32.6%) had some degree of depression; mild in 504 (21.4%), moderate in 163 (6.9%), and severe in 101 (4.3%). Multivariable analysis showed that depression was significantly higher at younger age. The odds of depression decreased by 3% with 1 year increase in age. It was higher in non-practicing ophthalmologists, especially those who were considerably worried about their training or professional growth, and those with difficulty in meeting living expenses. Conclusion A strikingly high proportion of ophthalmologists are psychologically affected and may require personalized mental health care.The present review describes the posterior segment complications following surgical management of glaucoma. Although the majority of glaucoma cases are managed medically, still a large number of patients may require surgery. Moreover, with the advent of newer surgical techniques and adjuncts, encountering retinal complications post-surgery is not uncommon. The incidence, signs, management, and prognosis of common complications such as anesthesia-related retinal toxicity, vitreous loss, suprachoroidal hemorrhage, serous choroidal detachment, hypotonic maculopathy, vitreous hemorrhage, retinal detachment and endophthalmitis will be discussed in detail. Awareness of these complications is necessary as their proper and timely management can save vision in an already compromised eye.The International Association of Contact Lens Educators (IACLE) is the leading provider of educational and information resources essential to contact lens educators worldwide. The New IACLE Contact Lens Course is its most important resource, used by members around the world to teach their students, the contact lens practitioners of the future. In 2019, IACLE celebrated the 40th Anniversary of its founding meeting. In this article, we trace the early years of the organization and describes its impact on contact lens education in India.Since the onset of the COVID-19 pandemic, there has been an advisory for regular and thorough cleaning of hands besides other measures such as social distancing and self-isolation. The rationale for the same is to prevent the transfer of the virus from hands that have come in contact with fomites. While both alcohol-based hand rubs (ABHR) or washing with soap and water are claimed to have been effective, hand sanitizers have gained more popularity due to the ease of use. The increased frequency of ABHR use and the aerosols generated pose a potential threat to the skin and exposed mucosal surfaces, especially that of the eye due to the proximity of use. The adverse effects of alcohol in these sanitizers can be manifold. An allergic or inflammatory response can occur depending on the predisposing or preexisting conditions. This article describes the risks, underlying mechanisms, and preventive measures for sanitizer aerosol-driven ocular surface disease.Oculoplastic surgeries encompass both emergency surgeries for traumatic conditions and infectious disorders as well as elective aesthetic procedures. The COVID-19 pandemic has brought about a drastic change in this practice. Given the highly infectious nature of the disease as well as the global scarcity of medical resources; it is only prudent to treat only emergent conditions during the pandemic as we incorporate evidence-based screening and protective measures into our practices. This manuscript is a compilation of evidence-based guidelines for surgical procedures that oculoplastic surgeons can employ during the COVID-19 pandemic. These guidelines also serve as the basic framework upon which further recommendations may be based on in the future, as elective surgeries start being performed on a regular basis.The COVID-19 pandemic has brought new challenges to the health care community. Many of the super-speciality practices are planning to re-open after the lockdown is lifted. However there is lot of apprehension in everyone's mind about conforming practices that would safeguard the patients, ophthalmologists, healthcare workers as well as taking adequate care of the equipment to minimize the damage. The aim of this article is to develop preferred practice patterns, by developing a consensus amongst the lead experts, that would help the institutes as well as individual vitreo-retina and uveitis experts to restart their practices with confidence. As the situation remains volatile, we would like to mention that these suggestions are evolving and likely to change as our understanding and experience gets better. Further, the suggestions are for routine patients as COVID-19 positive patients may be managed in designated hospitals as per local protocols. Also these suggestions have to be implemented keeping in compliance with local rules and regulations.Background & objectives Hepatitis A is prevalent worldwide and is among the leading cause of acute viral hepatitis in India. Major geographical differences in endemicity of hepatitis A are closely related to hygienic and sanitary conditions and other indicators of the level of socio-economic development. The present study was aimed to know the seropositivity prevalence and predominant circulating strain of HAV in a north India. Methods Patients with acute viral hepatitis were enrolled. Blood samples were collected over a period of one year from June 2016 to May 2017. Serum samples were tested for anti-immunoglobulin M (IgM) HAV antibodies. The seropositive samples were analyzed for HAV-RNA by real-time reverse transcription-polymerase chain reaction (RT-PCR). Samples detected on molecular assay were subjected to conventional semi-nested RT-PCR for VP1 gene. Further sequencing of amplified RT-PCR products was done, and data were analyzed. Results A total of 1615 patients were enrolled, and serum samples were collected and tested. The malefemale ratio was 1.31 with a mean age of 24.31±17.02 yr (range 0-83 yr). Among these, 128 (7.93%) were positive for anti-HAV IgM antibodies; 41.63 per cent of seropositive patients were in their childhood or early adolescent age group. Of all seropositive samples, 59 (46.09%) were positive for HAV RNA. Metabolism inhibitor Genotyping sequencing of 10 representative strains was carried out, and the circulating genotype was found to be IIIA. The nucleotide sequences showed homology among the strains. Interpretation & conclusions Our results showed that hepatitis A was a common disease in children with IIIA as a circulating genotype in this region. In approximately 50 per cent of cases, HAV RNA could be detected. Higher number of HAV IgM-seropositive cases was observed during monsoon period.
