    Background: Trachoma is endemic in several Pacific Island states. Recent surveys across the Solomon Islands indicated that whilst trachomatous inflammation-follicular (TF) was present at levels warranting intervention, the prevalence of trachomatous trichiasis (TT) was low. We set out to determine the relationship between chlamydial infection and trachoma in this population. Read More

    Australia remains the only developed country to have endemic levels of trachoma (a prevalence of 5% or greater among children) in some regions. Endemic trachoma in Australia is found predominantly in remote and very remote Aboriginal communities. The Australian Government funds the National Trachoma Surveillance and Reporting Unit to collate, analyse and report trachoma prevalence data and document trachoma control strategies in Australia through an annual surveillance report.

    Bacterial corneal ulcer associated with common variable immune deficiency.
    J Ophthalmic Inflamm Infect 2016 Dec 5;6(1):28. Epub 2016 Aug 5.
    Geisel School of Medicine at Dartmouth, Hanover, NH, USA.
    Common variable immune deficiency (CVID) is one of the most commonly diagnosed primary immunodeficiencies. Generally, patients have a history of recurrent sinopulmonary infections, hypogammaglobulinemia of two or more immunoglobulin isotypes, and impaired functional antibody responses. Reports of corneal involvement associated with CVID are limited. Read More

    Blinding Trachoma: Systematic Review of Rates and Risk Factors for Progressive Disease.
    PLoS Negl Trop Dis 2016 Aug 2;10(8):e0004859. Epub 2016 Aug 2.
    London School of Hygiene & Tropical Medicine, London, United Kingdom.
    Background: Sight loss from trachoma is the end result of a scarring disease process starting in early childhood and characterised by repeated episodes of conjunctival inflammation (active trachoma). Subsequently, the conjunctiva becomes scarred, causing the eyelashes to turn inwards and scratch the cornea (trichiasis), damaging the corneal surface and leading to corneal opacification and visual impairment. It is thought that this process is initiated and driven by repeated infection with Chlamydia trachomatis. Read More

    Low Prevalence of Ocular Chlamydia trachomatis Infection and Active Trachoma in the Western Division of Fiji.

    Clinical Research Department, London School of Hygiene & Tropical Medicine, London, United Kingdom.
    Background: Trachoma is the leading infectious cause of blindness and is caused by ocular infection with the bacterium Chlamydia trachomatis (Ct). While the majority of the global disease burden is found in sub-Saharan Africa, the Western Pacific Region has been identified as trachoma endemic. Population surveys carried out throughout Fiji have shown an abundance of both clinically active trachoma and trachomatous trichiasis in all divisions. Read More

    Prevalence of Trachoma in Car-Nicobar Island, India after Three Annual Rounds of Mass Drug Administration with Azithromycin.

    Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.
    Background: A high proportion of active trachoma infection in children of Car-Nicobar Island was reported through the Trachoma Rapid Assessment survey conducted in year 2010 by the same researchers. Annual mass drug treatment with azithromycin was administered from years 2010-12 to all individuals residing in this island for reducing the burden of active trachoma infection. A cross-sectional prevalence survey was conducted in the year 2013 to assess the post-treatment burden of trachoma in this population. Read More

    Trichiasis in ancient times.
    Clin Dermatol 2016 Jul-Aug;34(4):521-3. Epub 2016 Jan 22.
    Department of History of Medicine, Faculty of Medicine, University of Crete, Greece.
    Trichiasis, recognized since the time of Hippocrates, is a cause of ocular irritation that may result in scarring of the cornea and threaten sight. We have reviewed the original Greek medical texts made from the 1st to the 7th century ce and present the existing medical knowledge relating to trichiasis, including its clinical picture, cause, diagnosis, and treatment. Recognition of trichiasis as a stage of trachoma and its distinction from pseudotrichiasis gave the impetus for physicians of the era to use a significant number of pharmaceutical and surgical treatments.
