    Six Useful Apps and Glasses for Colourblind Patients: A Guide for Ophthalmologists

    Colourblindness makes many everyday tasks difficult—such as recognizing traffic signals, selecting clothes, or interpreting colour-coded information. For those affected, even simple activities can become challenging. At present, there is no permanent treatment available for colourblindness. However, ophthalmologists can play an important role in improving patients’ daily lives by recommending effective visual aids. With recent advances, several options are now within easy reach. Mobile applications can instantly identify and label colours, while specially designed glasses can enhance colour perception, particularly in red-green colourblindness. This short write-up highlights six practical aids—both apps and glasses—with links for direct access. By guiding patients to these resources, ophthalmologists can help them adapt better and manage their condition with greater confidence. 1. EnChroma Glasses EnChroma is a world leader in colourblind glasses designed to enhance red-green colour di

    Dos and Donts of Intraocular Foreign Bodies

    Penetrating ocular trauma with retained intraocular foreign body (IOFB) is a relatively common cause of avoidable blindness. IOFB is associated with 18%-41% of penetrating ocular injuries (1) Most of these injuries are workplace related (2). Young working age males are affected by a large majority (1). These patients need thorough evaluation and treatment on a priority basis to reduce visual morbidity. Following article describes Do’s and Don’ts of a patient with IOFB. Dos Take detailed history including medico legal aspects of trauma, circumstances of trauma, type of IOFB etc, Medico legal formalities must be completed at time of first contact History of systemic diseases should be elicited to r/o uncontrolled hypertension, diabetes mellitus, hyper or hypothyroidism etc. They may have implications in planning anesthesia and intraocular surgery Make sure visual acuity is evaluated and documented before proceeding with clinical evaluation Detailed documentation of each examination, pre

    Instrumentation for IOFB removal

    Removal of a retained intraocular foreign body (IOFB) is one of the very few ophthalmic emergencies which can cause a nightmare like situation at times even for an experienced surgeon. Careful evaluation and meticulous planning can help us achieve good anatomical and functional outcomes in these complex scenarios. It is extremely important to choose the right instrument for removal of IOFB based on its size, shape & nature. This will minimize any unnecessary prolonged maneuvers and also minimize trauma to the surrounding tissues. Here, we will focus on instrumentation that are available and needed for various posterior segment IOFB. IOFB extraction techniques vary according to factors such as the location, content, magnetic properties, and extent of local damage. There are two crucial steps in IOFB removal 1) Lifting the foreign body 2) Removal of foreign body. An important decision to be made while approaching an IOFB is to determine its nature, magnetic or non-magnetic. Endomagnets:

    Top Ten Tips - Shaping and Sharpening a Clinical Survey

    Surveys are helpful in understanding trends in the management of disease, the changes in the way a disease is treated and also how different factors can affect the choices a clinician makes. But the best surveys are the ones that bring out new information on topics, questions or trends that may seem familiar. Here are a few ways on maximising the responses to your survey questions: 1. Brief honest introduction: Usually invitations to participate in surveys are shared through email, social media platforms like Facebook or WhatsApp. It is important to include a brief and crisp introduction about who the investigators are and what does the survey aim to do. Also mention if the survey is anonymous or not: i.e. whether it requires the respondents to identify themselves or not and how long would it approximately take to fill up the survey form and who should be taking this survey. For example: Hello, Greetings. Request all ophthalmology residents in India to take this survey on cataract surg

    Polymerase Chain Reaction in Ocular Infections

    Newer technological progressions in molecular science have paved the way for a better understanding of infectious diseases. DNA-based molecular diagnostic techniques which are specific, sensitive, and rapid in the identification of the pathogen in the clinical specimen has been developed extensively over the past decades The rapid identi?cation of speci?c infectious agents is very important for the diagnosis of an ocular infection because the course of treatment and disease prognosis could be different from non-infectious diseases. Despite the availability of a wide variety of antimicrobial agents to treat these infections, specific treatment is delayed due to the inability to identify ocular pathogens quickly and accurately. PCR has emerged as an essential powerful rapid laboratory diagnostic technique complement the conventional gold standard “culture “, with special reference to difficult to grow or slow-growing microbial agents like viruses, Mycobacterium tuberculosis, anaerobic ba

    Normal flora /Microbiome of the Eye: 10 Facts

    1. Definition of Microbiome Microbiomes are communities of organisms (bacteria, fungi, viruses) that normally reside on any part of the human body (both external and internal) and are in a symbiotic relationship with the host. The members of the microbiome live in close harmony, sharing food and shelter and offering benefits to each other, e.g. some members give protection by secreting extracellular polymeric substances to form a protective covering of biofilm around the community, while some excrete metabolic by-products which are useful substrates for the others. 2. Relation of Microbiome with the host Most of the organisms of the microbiome provide support to the good health of the host (like preventing colonization by harmful pathogens by competing for shelter and food niches, occupying the pathogen receptor sites, or secreting antibiotics and metabolic by-products like acetic and lactic acids which harm such pathogens). But some of the members can also act as opportunistic pathoge

    Anomalies of Accommodation

    Ocular accommodation is an integral visual function that optimizes the visual perception through the focusing ability of the crystalline lens. This closed-loop system constantly interacts with the oculomotor system for finer focusing and alignment of the eyes under naturalistic binocular viewing conditions. This write-up is intended to provide an overview of the commonest anomalies of accommodation encountered by an eyecare practitioner through case-based learning. For detailed reading, the readers are requested to refer to Scheiman & Wick.1 The table below provides an overview of the commonest clinical signs, and symptoms seen in different anomalies of accommodation. 1, 2 ANOMALIES OF ACCOMMODATION DIAGNOSTIC CRITERIA ETIOLOGY PRIMARY SIGNS SYMPTOMS Accommodative insufficiency (Not due to sclerosis of the crystalline lens) Accommodation amplitudes (AA) lesser than expected for the patient’s age Usually idiopathic, can result from certain systemic medications Decreased AA for age (2D l

    How to Make Your Online Presence Felt : Tips & Tricks

    Introduction Covid has accelerated the digital shift for healthcare. We all know that It was probably going to take a few more years to happen but now as more and more people take the digital route for any requirement they may have, it becomes important for business owners to think about their online presence. This is true even for ophthalmologists. More so for those who have established their own practices versus working in an eye institute and this difference is because those who have established their own practices have in one way become entrepreneurs and whether they like it or not as time goes by the most important job as the owner of an ophthalmic practice would be to increase or drive patients to that practice. This is where online presence comes in. So what does online presence mean? When people look for you or for things you do there are places that showcase you or your practice.

    Astigmatism - The clinical pearls in Refractive care

    Preface: Astigmatism is a common type of refractive error that we come across in vision clinics on a regular basis. It causes the deterioration of retinal image quality and leads to specific vision-related symptoms. Prevalence of this condition is reported to vary with age, gender, and ethnicity. The clinical diagnosis and management of astigmatism necessitate an understanding of its nature and characteristics. Hence, this particular write-up is prepared as a consolidation of integrated information related to ‘astigmatism’ by focusing on its definition, classic types, relevant clinical evaluation components, and appropriate management options. What is astigmatism? Astigmatism is a type of refractive error/ametropia that occurs when parallel rays of light entering the ocular media (non-accommodative state) are not focused well on the retina. In an optical system with astigmatic error, light rays propagate in two different planes and the incident light rays fail to converge at a single f

    Zotero: A Quick Start Guide

    Tracking, collecting, organizing, reading, and assimilating the relevant references is an integral process of any scientific research. But this process is laborious when done manually. Hence was the development of reference management softwares (Zotero, Mendeley, EndNote, etc.) for the digitalization of relevant scholarly materials and facilitating the process of managing references. Reference managers provide an efficient way to the scientific authors (a) to track, collect and organize several reference materials. They also provide (b) virtual library with unlimited storage for reference materials with backup, (c) aid in easy management of the process of citation and automatic insertion of a reference/bibliography list in the required formatting style as well as (d) to create and collaborate with multiple libraries/groups. This particular chapter is prepared to give you an overview of the specific features and a quick start guide to use a popular reference manager ‘The Zotero’. What i
