Purpose To investigate if topical chlorhexidine 0.2%, which is low-cost and easy to formulate, is non-inferior to topical natamycin 5% for the treatment of filamentous fungal keratitis. Design Randomised controlled, single-masked, non-inferiority clinical trial. Participants Adults attending a tertiary-level ophthalmic hospital in Nepal with fila...

Background: To determine the normative data and reference value for photostress recovery time (PSRT) following exposure of the macula to light, in various age groups within the Indian population. Methods: Cross-sectional observational study performed from November 2015 to July 2016 in the Bangalore district of Karnataka state in India. We examined...

Background Nepal was under a severe lockdown for several months in 2020 due to the COVID-19 pandemic. There were concerns regarding misinformation circulating on social media. This study aimed to analyse the knowledge and awareness of COVID-19 amongst eye care professionals in Nepal during the first wave of the pandemic. Methodology Weinvited 600...

Background: Usage of digital devices has become one’s basic need. Digital eye strain is repeatedly noticed sequelae in optometry practice. Objectives: This study aims to estimate the different aspects of eye strain. Methodology: Altogether, 55 students with a mean age of 21.25 years, vision (≥6/9) were enrolled. A survey related to common astheno...

Background Microbial Keratitis (MK) is a leading cause of corneal blindness due to infection and its consequences, with a higher incidence in resource-limited nations. Hospital-based patient records from different parts of Nepal suggest patients often use traditional eye medicine to treat MK. Traditional healers (TH) within the community are often...

Background

A 39-year-old male with a history of COVID-19 infection presented with ocular manifestations: dendritic ulcer in the left eye cornea followed by diplopia in the same eye. Extraocular motility was restricted in the levo-lateral gaze with maximum diplopia measuring 25∆ exotropia. Slit lamp biomicroscopy showed dendritic patterned lesion with diffused...

Purpose: Unaddressed near vision impairment (NVI) affects more than 500 million people. Testing near vision is necessary to identify those in need of services. To make such testing readily accessible, we have developed and validated a new smartphone-based near visual acuity (NVA) test: Peek Near Vision (PeekNV). Methods: Two forms of the PeekNV...

Clinically diagnosing fungal keratitis (FK) is challenging; diagnosis can be assisted by investigations including in vivo confocal microscopy (IVCM), smear microscopy, and culture. The aim of this study was to estimate the sensitivity in detecting fungal keratitis (FK) using IVCM, smear microscopy, and culture in a setting with a high prevalence of...

With the emergence of vaccines for the novel coronavirus, a new ray of hope came into human society. Yet the adverse effects of vaccination on some candidates without allergic tests might cause a detrimental change in the future. An interesting case of panuveitis in a 34-year-old male after the ChAdOx1 nCoV19 (covishield) vaccination is reported he...

Background The aim of this study was to describe the health-seeking journey for patients with microbial keratitis (MK) in Nepal and identify factors associated with delay. Methods Prospective cohort study where MK patients attending a large, tertiary-referral eye hospital in south-eastern Nepal between June 2019 and November 2020 were recruited. W...

Fungal corneal infection (keratitis) is a common clinical problem in South Asia. However, it is often challenging to distinguish this from other aetiologies, such as bacteria or acanthamoeba. In this prospective study, we investigated clinical and epidemiological features that can predict the microbial aetiology of microbial keratitis in Nepal. We...

Background A new coronavirus causes COVID-19, a developing respiratory illness. Unfortunately, there is little information assessing healthcare workers' understanding of technology and preventative strategies during the Nepalese epidemic. Researchers from other subspecialties uncovered some mythical thoughts. As a result, we decided to put it to th...

Explanation about IVCM and applications of IVCM in various corneal pathologies.

Background: Accommodation changes ocular parameters, such as the anterior chamber volume (ACV), anterior chamber depth (ACD), anterior chamber angle (ACA), and pupil diameter (PD), which can reflect a risk of angle-closure glaucoma. Previous studies of changes in ocular anterior segment parameters, have used high diopters or maximum amplitude. Here...

Introduction: Fungal infections of the cornea, fungal keratitis (FK), are challenging to treat. Current topical antifungals are not always effective and are often unavailable, particularly in low-income and middle-income countries where most cases occur. Topical natamycin 5% is usually first-line treatment, however, even when treated intensively,...

Background: Nepal is currently under lockdown due to the COVID-19 pandemic with misinformation circulating on social media. This study aimed to analyse the knowledge and awareness of COVID-19 amongst eye care professionals in Nepal. Methodology: We invited 600 participants from 12 ophthalmic centres across Nepal to complete a qualitative, anonymous...

Invivo Confocal microscopy of corneal pathology

In eye care refractive error is common cause of avoidable visual impairment though diagnosis and treatment is simple and successful. AIM AND OBJECTIVE: To determine the prevalence of refractive errors amongst students of 10-16 years. METHODOLOGY: A prospective study of 2113 school children of 10–16 years age group in eastern Bangalore. Vision of th...
