Community-level Association between Clinical Trachoma and Ocular Chlamydia Infection after MASS Azithromycin Distribution in a Mesoendemic Region of Niger.

Ophthalmic Epidemiol 2019 Apr 8:1-7. Epub 2019 Apr 8.

b Francis I. Proctor Foundation , University of California , San Francisco , USA.

Purpose: The clinical sign trachomatous inflammation - follicular (TF) is used to monitor indication for and response to mass azithromycin distribution in trachoma-endemic communities. Here, we assess the relationship between TF, trachomatous inflammation - intense (TI), and infection with ocular Chlamydia trachomatis over time during annual mass azithromycin distribution.

Methods: We used data from a cluster-randomized trial of mass azithromycin distribution for trachoma control in a mesoendemic region of Niger. Read More

Progress Towards Elimination of Trachoma as a Public Health Problem in Eritrea: Results of a Systematic Review and Nine Population-based Prevalence Surveys Conducted in 2014.

Ophthalmic Epidemiol 2018 Dec;25(sup1):121-130

k Clinical Research Department , London School of Hygiene & Tropical Medicine , London , UK.

Purpose: To assess Eritrea's progress towards elimination of trachoma as a public health problem, we reviewed and compiled current knowledge on the distribution and burden of trachoma in Eritrea, then undertook further population-based surveys where indicated, with support from the Global Trachoma Mapping Project (GTMP).

Methods: For the systematic review, undertaken in March 2014, we searched (1) PubMed, using the terms ((blind* or trachoma or trichiasis) AND Eritrea); (2) the online database of rapid assessments of avoidable blindness; (3) our own grey literature collections; and (4) the Global Atlas of Trachoma database. In June and July 2014, we conducted nine population-based prevalence surveys, for each of which 30 villages were systematically selected with probability proportional to population size; in each village, 30 households were systematically selected.

A search for trachoma in Timor-Leste: no evidence to justify undertaking population-based prevalence surveys.

Ophthalmic Epidemiol 2018 Dec;25(sup1):131-137

j Department of Control of Neglected Tropical Diseases , World Health Organization , Geneva , Switzerland.

Purpose: We sought evidence to justify undertaking population-based trachoma surveys in Timor-Leste, believing that in the absence of such evidence, the country could be categorized as not needing interventions to eliminate trachoma.

Methods: We undertook a systematic review of published literature on trachoma in Timor-Leste, with results updated to 28 April 2018. We also undertook a series of clinic- and field-based screening exercises, consisting of: (1) in October 2015, conjunctival examination of all children attending a school in Vila, Atauro Island; (2) from 1 November 2016 to 30 April 2017, examination for trichiasis, by specifically-trained frontline eye workers, of all individuals presenting to the ophthalmic clinics of six referral hospitals and five district eye clinics; and (3) house-to-house case searches in a total of 110 households, drawn from three communities that were reported by investigators from the 2016 Rapid Assessment of Avoidable Blindness (RAAB) to include residents with trachoma.

Ophthalmic Epidemiol 2018 Dec;25(sup1):41-52

g Clinical Research Department , London School of Hygiene & Tropical Medicine , London , UK.

Purpose: Senegal is endemic for trachoma, an infectious and potentially blinding eye disease. To complete the country's district-level baseline map of trachoma, we conducted population-based surveys in 17 health districts that were suspected-endemic but had yet to be surveyed.

Methods: We randomly selected 30 clusters (villages) per district and 30 households per village, and estimated the district-level prevalences of trachomatous inflammation-follicular (TF) in children aged 1-9 years, and trichiasis in persons aged ≥15 years. Read More

Prevalence of trachoma in four marakez of Elmenia and Bani Suef Governorates, Egypt.

Ophthalmic Epidemiol 2018 Dec;25(sup1):70-78

o Clinical Research Department , London School of Hygiene & Tropical Medicine , London , UK.

Purpose: In 2015, to determine where interventions are needed to eliminate trachoma as a public health problem from Egypt, we initiated population-based prevalence surveys using the Global Trachoma Mapping Project platform in four suspected-endemic marakez (districts; singular: markaz) of the governorates of Elmenia and Bani Suef.

Methods: In each markaz, 30 households were selected in each of 25 villages. Certified graders examined a total of 3682 children aged 1-9 years in 2993 households, noting the presence or absence of trachomatous inflammation-follicular (TF) and trachomatous inflammation-intense (TI) in each eye.

Ophthalmic Epidemiol 2018 Dec;25(sup1):62-69

i Clinical Research Department , London School of Hygiene & Tropical Medicine , London , UK.

Purpose: In suspected trachoma-endemic areas of Yemen, we sought to determine the prevalence of the sign trachomatous inflammation-follicular (TF) in children aged 1-9 years, and the potential individual and household risk factors for TF in that age group. We also sought to determine the prevalence of trichiasis in adults aged ≥15 years.

Diagnostic Accuracy of Van Herick Technique to Detect Pre-Disease States of Primary Angle Closure Glaucoma in a Resource Constraint Region.

Ophthalmic Epidemiol 2019 Jan 8:1-8. Epub 2019 Jan 8.

a V S T Glaucoma Centre, Kallam Anji Reddy Campus , L V Prasad Eye Institute , Hyderabad , India.

Objectives: To critically evaluate diagnostic accuracy of the van Herick (vH) technique in detection of gonioscopically occludable angle in a rural population and to explore ways to improve accuracy of the technique Methods: The study cohort was formed by two-stage cluster random sampling. Peripheral anterior chamber depth grading was performed, using both traditional and modified (photographic comparison) vH techniques, under dark adapted and standard lighting conditions by a comprehensive ophthalmologist masked to the clinical features. The cut-off criterion for vH test was 25% of peripheral corneal thickness. Read More

Disordered sleep and myopia among adolescents: a propensity score matching analysis.

Ophthalmic Epidemiol 2019 Jan 2:1-6. Epub 2019 Jan 2.

c Department of Ophthalmology , the Second People's Hospital of Yunnan Province , Kunming , China.

Purpose: Observational studies have suggested a possible relationship between disordered sleep and myopia, but the association may be subject to selection biases. We aimed to minimize selection biases and assess the association by applying a propensity score matching (PSM) approach.

Methods: The study was designed as a school-based cross-sectional study on a Chinese cohort aged 13-14 years in rural areas of China. Read More

Optimising age adjustment of trichiasis prevalence estimates using data from 162 standardised surveys from seven regions of Ethiopia.

Ophthalmic Epidemiol 2018 Dec 28:1-8. Epub 2018 Dec 28.

a Clinical Research Department , London School of Hygiene & Tropical Medicine , London , UK.

Purpose: The prevalence of trichiasis is higher in females and increases markedly with age. Surveys carried out in the daytime, particularly in developing countries, are prone to find older individuals and females at home at the time of the survey. Population-level trichiasis estimates should adjust sample proportions to reflect the demographic breakdown of the population, although the most accurate method of doing this is unclear. Read More

Evaluation of a Single Dose of Azithromycin for Trachoma in Low-Prevalence Communities.

Ophthalmic Epidemiol 2019 02 13;26(1):1-6. Epub 2018 Dec 13.

a Division of Parasitic Diseases and Malaria , Centers for Disease Control and Prevention , Atlanta , GA , USA.

Purpose: Trachoma, caused by repeated ocular infection with Chlamydia trachomatis, is the leading infectious cause of blindness worldwide and is targeted for elimination as a public health problem. We sought to determine whether a one-time azithromycin mass treatment would reduce trachomatous inflammation-follicular (TF) levels below the elimination threshold of 5% in communities with disease prevalence between 5 and 9.9%.
