Abstract
BACKGROUND Trachomatous trichiasis (TT) is a painful, potentially blinding eye condition that can be managed through epilation or surgery. Women are affected by TT approximately twice as often as men and are believed to face gendered barriers to receiving surgical care to prevent vision loss. METHODS We used data from 817 cross-sectional surveys conducted during 2015-2019 in 20 African countries to estimate the prevalence difference (PD) between female and male eyes for four outcomes potentially indicating gender-related differences in TT management: (1) received surgery and developed postoperative TT (PTT), (2) never offered surgery, (3) offered surgery but declined it, and (4) offered epilation but never offered surgery. RESULTS The prevalence was modestly elevated among female eyes compared with male eyes for having PTT (PD:1.8 [95% confidence limits (CL): 0.6, 3.0]) and having declined surgery for the eye (PD: 6.2 [95% CL: 1.8, 10.7]). The proportion offered epilation was similar by gender (PD:0.5 [95% CL: -0.4, 1.3]), while never having been offered surgery was somewhat more prevalent among male eyes (PD: -2.1 [95% CL: -3.5, -0.7]). CONCLUSIONS Our results suggest potential gender differences in TT management. More research is needed to determine the causes and implications of the observed differences.

Abstract
PURPOSE Trachoma is an infectious eye disease caused by Chlamydia trachomatis. Infection causes conjunctival inflammation, which can be manifested by the sign known as trachomatous inflammation-follicular (TF). Repeated inflammation leads to eyelid scarring, which in susceptible individuals can cause in-turning of the eyelashes, referred to as trachomatous trichiasis (TT). This article describes 23 population-based surveys conducted in northern and central Benin to determine TF and/or TT prevalence for trachoma elimination purposes. METHODS A total of 18 surveys estimated the prevalence of both TF and TT: two baseline surveys, eight impact surveys after implementation of interventions against trachoma, and eight surveillance surveys. Five other evaluation units (EUs) were surveyed for TT only. To estimate the TF prevalence, a target sample size of 1701 (baseline) and 1164 1-9-year-olds (impact and surveillance) was required, whereas 2818 ≥ 15-year-olds were required to estimate the less prevalent TT. In each EU, individuals were selected by two-stage cluster sampling and examined by certified graders for TF and/or TT. RESULTS A total of 68,613 people were examined. TF prevalence estimates were under the 5% elimination threshold in all surveys. TT prevalence estimates were above the 0.2% elimination threshold in all five TT-only surveys and in four impact surveys, ranging from 0.2-0.57. CONCLUSION TF prevalence in Benin is low, but TT was above 0.2% in nine districts. Increased case-finding and continuing efforts to improve surgery accessibility will be needed to reduce the burden of TT in Benin.

Global trends in blindness and vision impairment due to corneal opacity 1984-2020: a meta-analysis. Ophthalmology 2023:S0161-6420(23)00187-2. [PMID: 36963570 PMCID: PMC10355344 DOI: 10.1016/j.ophtha.2023.03.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Revised: 03/10/2023] [Accepted: 03/15/2023] [Indexed: 03/26/2023] Open
Abstract
TOPIC We provide global estimates of the prevalence of corneal blindness and vision impairment in adults 40 years and older and examine the burden by age, gender, and geographic region from 1984-2020. CLINICAL RELEVANCE Corneal opacities (CO) are among the top five causes of blindness worldwide, yet the global prevalence, regional differences, and risk factors are unclear. METHODS Abstracted data from the published literature and surveys were obtained from the Global Burden of Disease Vision Loss Expert Group. We supplemented this by an independent systematic literature search of PubMed, Embase, Web of Science, Scopus, and Cochrane. Studies that provided CO vision impairment data based on population-based surveys for subjects 40 years of age or older were included, for a total of 244. For each of the four outcomes of blindness and moderate to severe vision impairment (MSVI) caused by trachomatous and non-trachomatous CO (NTCO), time trends and differences in prevalence by region, age, and sex were evaluated using a Poisson log-linear model with a generalized estimating equation method. Age-standardized estimates of global prevalence of blindness and MSVI were calculated using the 2015 United Nations standard populations. RESULTS The global prevalence of blindness due to NTCO in those 40 years and older was 0.081% (95% CI=0.049% to 0.315%); MSVI was 0.130% (95% CI= 0.087% to 0.372%). There was a significant increase with age (prevalence rate ratio=2.15, 95% CI=1.99-2.32). Latin America and Europe had the lowest rates, with 2-8 fold higher rates of blindness/MSVI in the other regions. The global prevalence of blindness due to trachomatous CO in those 50 years and older was 0.013% (95% CI=0.006% to 0.043%); MSVI was 0.180% (95% CI=0.006% to 0.049%). Trachomatous CO blindness and MSVI increased with age and female gender, and rates were significantly higher in the African regions; a decrease in blindness rates over time was found (prevalence rate ratio estimate=0.91, 95% CI=0.86-0.96). CONCLUSION An estimated 5.5 million persons worldwide are bilaterally blind or with MSVI due to CO, with an additional 6.2 million unilaterally blind. Trachomatous CO blindness is declining over time, likely due to the massive scaleup of the global trachoma elimination program and overall socioeconomic development.

Abstract
Trachoma is a neglected tropical disease caused by infection with conjunctival strains of Chlamydia trachomatis. It can result in blindness. Pathophysiologically, trachoma is a disease complex composed of two linked chronic processes: a recurrent, generally subclinical infectious-inflammatory disease that mostly affects children, and a non-communicable, cicatricial and, owing to trichiasis, eventually blinding disease that supervenes in some individuals later in life. At least 150 infection episodes over an individual's lifetime are needed to precipitate trichiasis; thus, opportunity exists for a just global health system to intervene to prevent trachomatous blindness. Trachoma is found at highest prevalence in the poorest communities of low-income countries, particularly in sub-Saharan Africa; in June 2021, 1.8 million people worldwide were going blind from the disease. Blindness attributable to trachoma can appear in communities many years after conjunctival C. trachomatis transmission has waned or ceased; therefore, the two linked disease processes require distinct clinical and public health responses. Surgery is offered to individuals with trichiasis and antibiotic mass drug administration and interventions to stimulate facial cleanliness and environmental improvement are designed to reduce infection prevalence and transmission. Together, these interventions comprise the SAFE strategy, which is achieving considerable success. Although much work remains, a continuing public health problem from trachoma in the year 2030 will be difficult for the world to excuse.

Abstract
Background Trachomatous trichiasis is the leading infectious cause of blindness worldwide. The World Health Organization recommends eyelid surgery to reduce the risk of visual impairment from trichiasis. Unfortunately, the number of cases operated has grown less than expected. An understanding of barriers is fundamental for instituting measures to increase surgical uptake. Therefore, the aim of this study was to explore barriers of TT surgery implementation. Methods A qualitative study design was employed in December 2019. Purposive sampling technique was used to select three districts from Gamo zone, Southern Ethiopia. We conducted 9 FGDs and 12 in-depth interviews. Data was collected by audio tape recorder in Amharic and Gamogna languages and then transcribed to English language. The recorded interviews and focus group discussions were transcribed to verbatim (written text) and thematic analysis was done manually and reported accordingly. Findings we explored a number of barriers that hindered implementation of trichiasis surgery. The recurrence of trichiasis after surgery was the main challenges faced by operated individuals. The other barriers reported are negative perception towards trichiasis surgery, lack of logistic and supplies, transportation access problem for remote communities, inadequate trained health professional, less commitment from higher officials, lack of interest of integrated eye care workers due to incentive issues, believes of patients waiting supernatural power for healing service and carelessness of patients to undertake operation. Conclusion and recommendation Post-surgical trichiasis, lack of commitment from government officials and negative perception of patients towards the disease were considered as the reported barriers for implementation of trachomatous trichiasis. Closely supervising the integrated eye care workers would be the first task for district health offices to increase the uptake and improve the quality of service. Logistics and supplies should be made available and adequate to address all affected people in the community. Despite the scale-up of surgical services to eliminate blinding trachoma, the current surgical activity is not effectively tackling the backlog. There are limited studies done previously that explore barriers on implementation of trachomatous trichiasis surgery in Ethiopia. Therefore, understanding barriers is fundamental for instituting measures to increase surgical uptake. Hence, reliable population-based data on barriers towards trichiasis surgery implementation is very crucial for planning effective trachoma control programs, for the country like Ethiopia where trachoma ranks the first in the list of high burden countries. Our finding showed that post-surgical trichiasis, lack of commitment from government officials and negative perception of patients towards the disease were considered as the reported barriers for implementation of trachomatous trichiasis. Closely supervising the integrated eye care workers would be the first task for district health offices to increase the uptake and improve the quality of service. Logistics and supplies should be made available and adequate to address all affected people in the community.

Abstract
Background Trachoma is the second leading cause of blindness in the world affecting the poorest communities. Despite many interventions undertaken on prevention and control for trachoma, Ethiopia has failed to achieve the 2020 elimination goal. Objective To assess knowledge, attitude, practice and its associated factors toward trachoma infection among people living in Arba Minch Zuria district Gamo zone, Southern Ethiopia. Methods A community-based cross-sectional study was conducted from December 2019 to June 2020. Data were collected using a pretested interviewer-administered questionnaire from 796 randomly selected individuals. Epi Info version 7 was used to enter and clean the data and exported to SPSS V20 for analysis. A multivariable logistic regression analysis model was fitted to identify factors associated with the outcome variables. Findings Among 796 interviewed participants, 611 (76.8%) had inadequate knowledge toward trachoma infection and 244 (30.7%) had unfavorable attitude. Individuals who had no formal education (AOR=0.365, 95%CI: 0.212–0.626) and primary education (AOR=0.58, 95%CI: 0.35–0.962) were negatively associated with adequate knowledge towards trachoma infection. Being a farmer (AOR=0.063, 95%CI: 0.008–0.52), merchant (AOR=0.022, 95%CI: 0.003–0.194), student (AOR=0.026, 95%CI: 0.003–0.225) or housewife (AOR=0.03, 95%CI: 0.004–0.256) were negatively associated with adequate knowledge. Those study subjects whose wealth index were lowest (AOR=0.49, 95%CI: 0.27–0.878), second (AOR=0.38, 95%CI: 0.21–0.69) and middle (AOR=0.36, 95%CI: 0.199–0.658) percentiles negatively associated with adequate knowledge. A short distance to fetch water (AOR=2.53, 95%CI: 1.18–5.415) was positively associated with adequate knowledge about trachoma infection. Environmental cleanliness (AOR=2.224, 95%CI: 1.518–3.257), being male (AOR=1.848, 95%CI: 1.332–2.565) and distance from home to health facility (AOR=1.845, 95%CI: 1.308–2.600) were significantly associated with attitude status. Conclusion Considerable numbers of people have unfavorable attitude and inadequate knowledge about trachoma infection. Awareness creation through community mobilization and sensitization should be strengthened.

Abstract
BACKGROUND Trachoma is the most common infectious cause of blindness in the globe. Trichiasis surgery is the best treatment option for this disease. Despite efforts done to eliminate blinding trachoma, there is limited evidence on the surgical uptake of trachoma trichiasis in Ethiopia. This study was aimed to assess the uptake of trachoma trichiasis surgery in Southern Tigray, Ethiopia. METHODS Mixed cross-sectional study was employed among 409 participants. Study participants were selected using a consecutive sampling technique. Pretested and interviewer-administered data were collected using a structured questionnaire. Binary and multivariable logistic regression was done to identify associated factors. Adjusted odds ratios 95% CI was estimated to show the strength and direction. Variables with p-values <0.05 were considered statistically significant. For qualitative data, 4 focus group discussions were conducted with 40 participants and described by thematic analysis then triangulated with quantitative findings. RESULTS About 234 (57.9%, 95% CI: (53.2, 62.9)) participants utilized trachoma trichiasis surgery (TT). History of trachoma trichiasis (TT) for >2 years [AOR: 0.4, 95% CI: (0.22, 0.72)], informed about surgery program by health workers [AOR: 0.3, 95% CI: (0.13, 0.71)], history of TT surgery [AOR: 0.18, 95% CI: (0.05, 0.6)], absence of someone to care the family [AOR: 14, 95% CI: (6.9, 28.6)], companion [AOR: 8.9, 95% CI: (4.3, 18.3)], nearby health facility [AOR: 2.4, 95% CI: (1.1, 5.4)], work load [AOR: 8.8, 95% CI: (4.6, 17)], fear [AOR: 4.3, 95% CI: (1.8, 10)], and believing eye drop can treat TT [AOR: 3.9, 95% CI: (1.4, 11)] were significantly associated factors. CONCLUSION More than half of the participants accepted the TT surgical uptake. Strengthening community awareness on proper eye care, and effective treatment options, and addressing the negative attitude towards surgical treatment in the community are important measures to achieve the elimination target of trachoma.

Patient perceived barriers to surgical follow-up: Study of 6-month post-operative trichiasis surgery follow-up in Tanzania. PLoS One 2021; 16:e0247994. [PMID: 33739975 PMCID: PMC7978239 DOI: 10.1371/journal.pone.0247994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Accepted: 02/17/2021] [Indexed: 11/19/2022] Open
Abstract
Background Post-surgical follow-up is a challenge in low- and middle-income countries. Understanding barriers to trachomatous trichiasis (TT) surgical follow-up can inform program improvements. In this study, patient perceived barriers and enabling factors to follow-up after TT surgery are identified. Methods A longitudinal study was carried out in a community-based cohort of persons who received TT surgery in Bahi district, Tanzania. Questionnaires were administered before TT surgery and again after the scheduled 6-month follow-up. Those who did not return were examined at their homes. Results At baseline, 852 participants were enrolled. Of these, 633 (74%) returned at 6 months and 128 (15%) did not and were interviewed at home. Prior to surgery, attenders were more likely to report familiarity with a community health worker (CHW) (22% vs. 14%; p = 0.01) and less likely to state that time constraints are a potential reason for failure to follow-up (66% vs. 74%; p = .04). At follow-up, non-attenders were more likely to endorse barriers pertaining to knowledge about the need for follow-up, lack of transportation, and satisfaction with surgery. There was no difference in post-operative TT between attenders and non-attenders (23% vs. 18% respectively; p = 0.25). Conclusions The outcome of surgery was not a barrier to follow-up. However, better integration of CHWs into their communities and work at coordinating post-surgical care may improve follow-up rates. Moreover, provision of transportation and implementation of effective reminder systems may address patient-perceived barriers to improve follow-up.

Abstract
Background Approximately 1.9 million people have become blind or visually impaired from trachoma, the leading cause of infectious blindness. Trachoma prevalence surveys conducted in Sudan have shown that thousands of Sudanese suffer from the advanced stages of the disease, trachomatous trichiasis (TT), and warrant sight-saving surgery. Sudan’s National Trachoma Control Program (NTCP) provides free TT surgery; however, given that many TT patients live in remote areas with limited access to health services, identifying patients and providing eye care services has proved challenging. For this reason, the Sudan NTCP piloted a systematic TT case-finding approach to identify patients. Methods In Gedarif state, 11 villages in Baladyat el Gedarif locality and 21 villages in West Galabat locality were included in a TT case-searching activity from September to November 2018. TT case finders were selected from the villages where the activity took place and were trained by ophthalmic medical assistants to identify possible patients. Results Of 66 626 villagers examined, 491 were identified as having TT by TT case finders. Of those, 369 were confirmed as true cases by the TT surgeons, a 75.2% (369/491) success rate. Conclusions The TT case-finding approach provides an example of an effective method for identifying TT patients and should be expanded to other parts of the country known to be endemic for trachoma.

Middle East Afr J Ophthalmol 2020; 27:14-21. [PMID: 32549719 PMCID: PMC7276166 DOI: 10.4103/meajo.meajo_75_19] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 10/06/2019] [Accepted: 02/18/2020] [Indexed: 11/10/2022] Open
Abstract
PURPOSE: The purpose of the study was to assess the feasibility of a mobile data collection app for use in trichiasis surgical audits in the Melfi and Mangalme districts of the Guera region of the Republic of Chad and to perform a cost analysis to determine if the auditing mechanism could be implemented nationally. MATERIALS AND METHODS: Patients who underwent trichiasis surgery 6 months prior and who had follow-up 7–14 days after surgery were included in the study. Each surgeon had a sample of 20% of operated eyelids; nine surgeons with data for ≥20 eyelids were included. A trichiasis recurrence rate of ≥25% suggested that the surgeon needed retraining. Smartphones captured data using the data collection app, which transmitted data to an online server. Direct costs and supervision costs were collated and summed. RESULTS: There were 916 eyelids operated on; 170 patients (269 eyelids, 29% follow-up rate) participated in the audit. Twenty participants (11.8%) had recurrence. The mean recurrence rate among surgeons was 8.3% (standard deviation: 0.07%; range: 0%–17.9%). None had a recurrence rate of ≥25%; thus, no retraining was necessary. The total cost of the audit was US$15,111.25 ($12,882.28 in direct costs and $2,228.97 in supervision costs). CONCLUSIONS: The simple, easy-to-use, and low-cost mobile auditing mechanism is a practical solution for conducting surgical audits in remote and resource-limited settings and is undergoing national scale-up by the Chadian trachoma elimination program.

Abstract
PURPOSE Trachoma, a chronic conjunctivitis that can result in vision loss from trichiasis, is targeted for global elimination by 2020. Several milestones in the long process towards elimination are noteworthy for the impact they have had on changing or accelerating progress. The purpose of this review is to describe the milestones and the impact they have had both for trachoma elimination and beyond. FINDINGS Eight milestones are presented. They are discovery of the causative agent; development of a clinical grading scheme; establishment of the World Health Organization Alliance for the Global Elimination of Trachoma by 2020; setting targets that define elimination; building an evidence base for trichiasis surgery; azithromycin donation programme; use of the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, and Environmental improvement); and The Global Trachoma Mapping Project. SUMMARY These milestones have significantly pushed the progress towards elimination. Despite challenges to achieving the goal of elimination by 2020, there is continued commitment into the future to ensure that this preventable cause of blindness is no longer a threat.

Abstract
Purpose: To compare severity of visual field (VF) loss at first presentation in glaucoma clinics in England and Tanzania.Methods: Large archives of VF records from automated perimetry were used to retrospectively examine vision loss at first presentation in glaucoma clinics in Tanzania (N = 1,502) and England (N = 9,264). Mean deviation (MD) of the worse eye at the first hospital visit was used as an estimate of detectable VF loss severity.Results: In Tanzania, 44.7% {CI95%: 42.2, 47.2} of patients presented with severe VF loss (< -20 dB), versus 4.6% {4.1, 5.0} in England. If we consider late presentation to also include cases of advanced loss (-12.01 dB to -20 dB), then the proportion of patients presenting late was 58.1% {55.6, 60.6} and 14.0% {13.3, 14.7}, respectively. The proportion of late presentations was greater in Tanzania at all ages, but the difference was particularly pronounced among working-age adults, with 50.3% {46.9, 53.7} of 18-65-year-olds presenting with advanced or severe VF loss, versus 10.2% {9.3, 11.3} in England. In both countries, men were more likely to present late than women.Conclusions: Late presentation of glaucoma is a problem in England, and an even greater challenge in Tanzania. Possible solutions are discussed, including increased community eye-care, and a more proactive approach to case finding through the use of disruptive new technologies, such as low-cost, portable diagnostic aids.

Abstract
PURPOSE Trichiasis case finding is challenging in many trachoma endemic countries. We sought to determine how the use of an inexpensive hand-held magnifier with light source aids in the diagnosis of people with trichiasis. METHODS We undertook a study on the use of the "Wilson", an inexpensive hand-held magnifier with light source between two groups of trained case finders: community drug distributors (CDD) volunteers and non-health volunteers. Each group was randomly allocated to be provided a Wilson or not. We compared the number of people with suspected trichiasis and the proportion of true cases referred by each group. Focus group discussions explored the perceptions of the case finders that used the Wilson on its utility in the diagnosis of trichiasis and its ease of use. RESULTS Among the 121 case finders, 61 were CDD volunteers (31 were provided the Wilson) and 60 were non-health worker volunteers (30 were provided the Wilson). Case finders that used the Wilson were 4.57 times (95% CI 2.46-8.47) more likely to have patients presenting confirmed as trichiasis compared to those not using the Wilson. Case finders that used the Wilson felt the instrument was easy to use, enlarged the eyelashes and made diagnoses of trichiasis easier. DISCUSSION In Nigeria it appears that the Wilson is easy to handle and use among trichiasis case finders enhances the diagnosis of trichiasis.

Abstract
BACKGROUND Trachomatous trichiasis is one of the leading causes of preventable blindness worldwide. A relatively simple surgery can spare vision. Although this surgery is usually performed free of charge in endemic regions, multiple studies indicate that surgical refusal is common. Prior studies have attempted to examine these reasons, although they generally rely on patient recall months to years after the surgery was offered. This study set out to determine major decision-making factors at the time of refusal. In addition, this study looked for ways to help increase surgical uptake by targeting modifiable factors. METHODOLOGY/PRINCIPAL FINDINGS We used a combination of focus groups, interviews with community health workers, and individual interviews with trichiasis patients who refused surgery to understand their decision-making. We found that several factors influenced surgical refusals, including misconception regarding recovery time, inability to find a post-surgical caregiver, and the time of year of the surgical campaign. Fear of the surgery itself played a minimal role in refusals. CONCLUSIONS/SIGNIFICANCE Trichiasis patients refuse surgery for many reasons, but a large percentage is due to lack of information and education, and is, therefore, modifiable within the structure of a surgical outreach project. To address this, we developed a "frequently asked questions" (FAQ) document aimed at community health workers, which may have helped to decrease some of the misconceptions that had led to prior refusals.
