Interventions to improve gender equity in eye care in low-middle income countries: A systematic review.

Ophthalmic Epidemiol 2019 Feb 15:1-11. Epub 2019 Feb 15.

b Seva Canada Society , Vancouver , Canada.

Purpose: Women bear an inequitable burden of blinding conditions compared to men primarily because they have more limited access to eye care services. This systematic review sought evidence regarding interventions to increase gender equity in eye care.

Methods: We searched MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, and EBSCO CINAHL, and contacted experts to identify studies in low- and middle-income countries of health services interventions for age-related cataract, childhood cataract, and trachoma. Read More

Ophthalmic Epidemiol 2019 Feb 4:1-8. Epub 2019 Feb 4.

a Glaucoma Services , Dr. Shroff's Charity Eye Hospital , Daryaganj , New Delhi , India.

Purpose: To study the current profile of secondary glaucoma in all age groups of patients presenting to a tertiary eye care hospital in Northern India Materials and methods: In this retrospective study, files of 5725 patients who were newly diagnosed to have glaucoma in our tertiary eye care centre from January 2014 to December 2016 were reviewed. Detailed data were collected from patient's records, including history, best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy findings, gonioscopy, and fundus findings. Demographic data, aetiology, and management in all these patients were also noted. 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

e Iberoamerican Cochrane Centre, Institute of Biomedical Research (IIB Sant Pau) , Barcelona , Spain.

Purpose: Properly conducted controlled clinical trials (CCTs) provide the highest level of evidence for optimising decision-making in healthcare. Electronic search strategies do not exhaustively retrieve them, because of issues related to indexing, exclusion of journals in languages other than English, among others. A handsearch approach is therefore warranted. Read More

Factors Associated with Non-compliance for Diabetic Retinopathy Follow-up in an Urban Safety-Net Hospital.

Ophthalmic Epidemiol 2018 Oct - Dec;25(5-6):443-450. Epub 2018 Aug 6.

a Shiley Eye Institute, Department of Ophthalmology , University of California , San Diego , California , USA.

Purpose: Diabetic retinopathy (DR) is the leading cause of preventable blindness in working-aged adults, and compliance in ophthalmic follow-up appointments is critical to prevent vision loss. However, barriers to follow-up care have not been well studied, especially in socio-economically disadvantaged groups. We investigated the risk factors for non-compliance to DR follow-up appointments in a safety-net county hospital. Read More

A diagnostic instrument to help field graders evaluate active trachoma.

Ophthalmic Epidemiol 2018 Oct - Dec;25(5-6):399-402. Epub 2018 Aug 1.

c School of Medicine , University of St Andrews , St Andrews , UK.

The SAFE strategy (Surgery for trichiasis, mass treatment with Antibiotics to clear ocular Chlamydia trachomatis infection, and Facial cleanliness and Environmental improvement to reduce transmission) is being used to eliminate trachoma as a public health problem. Decisions on whether or not to implement the A, F, and E components of SAFE are made on the basis of the prevalence of trachomatous inflammation-follicular (TF) in 1-9-year-olds. TF has a precise definition: at least five follicles, each of which is at least 0. Read More

Assessment of Response Bias Is Neglected in Cross-Sectional Blindness Prevalence Surveys: A Review of Recent Surveys in Low- and Middle-Income Countries.

Ophthalmic Epidemiol 2018 Oct - Dec;25(5-6):379-385. Epub 2018 Jul 30.

d Department of Infectious & Tropical Diseases, International Centre for Eye Health, Clinical Research Unit , London School of Hygiene and Tropical Medicine , London , United Kingdom.

Purpose: Findings from cross-sectional blindness prevalence surveys are at risk of several biases that cause the study estimate to differ from the 'true' population prevalence. For example, response bias occurs when people who participate ('responders') differ from those who do not ('non-responders') in ways that affect prevalence estimates. This study aimed to assess the extent to which response bias is considered and occurs in blindness prevalence surveys in low- and middle-income countries (LMICs). Read More
