Examining the association between perceived stigma, its correlates, and restrictions in participation among persons with disabilities in Nepal: a cross-sectional study.

BACKGROUND: Disability stigma in low- and middle-income countries is one of the most persistent and complex barriers limiting persons with disabilities (PwDs) from enjoying their rights and opportunities. Perceived stigma among PwDs and its impact on participation restriction is rarely assessed in Nepal. OBJECTIVE: This study aimed to measure the extent of perceived stigma by PwDs, identify its relationships with specific demographic factors, and assess the impact on social participation. METHODS: A cross-sectional survey was conducted between May and July 2022 among PwDs in Nepal, with a sample of 371. The Explanatory Model Interview Catalog (EMIC) stigma scale and P-scale suitable for people affected by stigmatized conditions were used, and the generated scores were analyzed. One-way ANOVA was performed to determine group differences for sociodemographic variables, and linear regression and correlational analysis were used to identify their association and measure the strength and direction of the relationship. RESULTS: The mean stigma score was 16.9 (SD 13.8). 42% of respondents scored higher than the mean. The scores differed significantly by disability type, caste and ethnicity, education, occupation, and household wealth. Over 56% reported participation restriction, and 38% had severe/extreme restriction. Approximately 65% of participants with intellectual disabilities, 53% with multiple disabilities, and 48.5% of persons with severe or profound disabilities experienced severe or extreme restrictions. Perceived stigma had a positive correlation with Disability type (r = 0.17, P < 0.01) and negative correlations with Severity of disability (r= -0.15, P < 0.05), and Household wealth (r= -0.15, P < 0.01). Education was inversely associated with both stigma (r= -0.24, P < 0.01), and participation restriction (ß= -9.34, P < 0.01). However, there was no association between stigma and participation restriction (ß= -0.10, P > 0.05). CONCLUSION: All participants exhibited stigma in general; however, the severity varied based on disability type, level of education, and sociocultural circumstances. A large proportion of participants reported facing a high degree of restrictions in participation; however, no association was detected between perceived stigma and participation restriction. A significant negative linear correlation was observed between education and participation restriction. Stigma reduction programs focusing on education and empowerment would be especially important for overcoming internalized stigma and increasing the participation of PwDs.

Effect of exposure to biomass smoke from cooking fuel types and eye disorders in women from hilly and plain regions of Nepal.

BACKGROUND/AIM: To study the association between exposure to biomass smoke from cooking fuels andi cataract, visual acuity and ocular symptoms in women. METHODS: We conducted a community-based cross-sectional study among women (≥20 years and without a previous diagnosis of cataract, ocular trauma or diabetes or those taking steroids) from hilly and plain regions of Nepal. Eligible participants received an interview and a comprehensive eye assessment (cataract development, visual acuity test and ocular symptoms). Participants' data on demographics, cooking fuel type and duration of use, and cooking habits were collected. We addressed potential confounders using the propensity score and other risk factors for ocular diseases through regression analysis. RESULTS: Of 784 participants, 30.6% used clean fuel (liquefied petroleum gas, methane, electricity) as their primary current fuel, and the remaining 69.4% used biomass fuels. Thirty-nine per cent of the total participants had cataracts-about twofold higher in those who currently used biomass fuel compared with those who used clean fuel (OR=2.27; 95% CI 1.09 to 4.77) and over threefold higher in those who always used biomass. Similarly, the nuclear cataract was twofold higher in the current biomass user group compared with the clean fuel user group (OR=2.53; 95% CI 1.18-5.42) and over threefold higher among those who always used biomass. A higher proportion of women using biomass had impaired vision, reported more ocular symptoms compared with those using clean fuel. Severe impaired vision and blindness were only present in biomass fuel users. However, the differences were only statistically significant for symptoms such as redness, burning sensation, a complaint of pain in the eye and tear in the eyes. CONCLUSIONS: Cataract was more prevalent in women using biomass for cooking compared with those using clean fuel.

Prevalence and Causes of Visual Impairment and Blindness in Three Ecological Regions of Nepal.

INTRODUCTION: Visual impairment and blindness are significant public health issues worldwide. The objective of this study was to estimate the prevalence and causes of moderate to severe visual impairment (MSVI) and blindness in people aged 15 years and above across three ecological regions of Nepal. MATERIALS AND METHODS: A comparative cross-sectional study was conducted in one district in each of the three ecological regions of Nepal. Number of participants from each region was distributed as per the prevalence findings of pilot study, with 2815 participants enrolled in Dolakha, 1509 in Dhading and 910 in Sarlahi. Intensive training was provided to health workers on how to conduct door-to-door enumeration, visual acuity testing and referral when indicated for comprehensive ocular examination by technicians and ophthalmologists to diagnose and treat ocular morbidities. Collected data were analyzed using standard software. For categorical data, frequency, percentage and 95% CI were calculated and statistical tests were done using Chi-square/Fisher exact test. RESULTS: Altogether 5234 participants were enrolled in the study (participation rate 96.4%). The overall prevalence of MSVI was 9.5% (495). It was 4.7% (133) in the mountainous region, 11.2% (169) in the Hill and 21.2% (193) in the Tarai. In those aged 15-49 years, MSVI prevalence was 1.5% (52) and 25.1% (433) in ≥50 years. The overall prevalence of blindness was 0.9% (47). It was 0.2% (6) in 15-49 and 2.3% (41) in ≥50 age groups. More than 95% visual impairment and blindness were due to cataract and uncorrected refractive error. Cataract was the leading cause of visual impairment and blindness (290, 53.5%), followed by uncorrected refractive error. CONCLUSION: The prevalence of visual impairment and blindness varied significantly with age, ethnicity and locality. The management of uncorrected refractive error and operable cataract would reduce nine in ten cases of moderate to severe visual impairment and blindness.

Glaucoma Screening in Family Members of Glaucoma Patients at a Tertiary Eye Hospital in Eastern Region of Nepal.

INTRODUCTION: The second most common cause of blindness in the world is glaucoma. Family history plays an important role in early detection and management of patients with glaucoma. The main objective of this study was to determine the prevalence of glaucoma in first degree relatives of Primary open angle glaucoma (POAG) and Primary angle closure glaucoma (PACG) patients. Glaucoma awareness among the first degree relatives was also assessed. MATERIALS AND METHODS: A  cross sectional hospital based study was designed to examine and diagnose glaucoma among first degree relatives of patients with POAG and PACG, attending the outpatient department at Ramlal Golchha Eye Hospital in the Eastern region of Nepal from June 2016 to May 2017. A comprehensive eye examination was conducted by a glaucoma specialist at the hospital. All subjects underwent vision screening, refraction, slit lamp biomicroscopy, intraocular pressure (IOP) measurement, gonioscopy and a dilated fundus examination. All glaucoma suspects and those diagnosed with glaucoma were enrolled for visual field examination. RESULTS:  Two hundred and twenty-seven first degree relatives of 72 patients were invited for the examination. Out of 227 individuals, 131 (males 67.94%, females 32.06%) agreed to participate in the study. A total of 23 (17.56%) individuals were diagnosed with glaucoma, 10 (43.47%) as POAG and 13 (56.52%) as PACG. Fourteen percent of parents, 22% of siblings and 9% of off-springs had open angle glaucoma. Among 13 PACG participants, 26.08% of parents, 26.08% of siblings and 4.34% of off-springs had angle closure glaucoma. Awareness among first degree relatives diagnosed with glaucoma was 21.74%. CONCLUSION:  The prevalence of glaucoma among first degree relatives of glaucoma patients was higher than individuals without family history of glaucoma. Promoting awareness on glaucoma and the timely screening of family members can lead to early detection and prevention of blindness from the disease. .

Female Clients Satisfaction towards Primary and Secondary Eye Health Facilities and Cost of Eye Care in Nepal.

INTRODUCTION: In Nepal, females suffer from disproportionately higher burden of blindness and vision impairment with low access to eye care. The available knowledge is inadequate to address the issues related to gender and generate information to reduce the gender disparity. The aim of this study was to determine female clients' satisfaction with services at eye facilities in Nepal and to estimate the cost of cataract surgery. MATERIALS AND METHODS: Exit interviews were conducted in 2018 with 308 female clients from eight facilities in five districts. Face to face interviews were conducted using a pretested semi-structured questionnaire adopted from the midterm review of Vision 2020. RESULTS: The mean age of participants was 54±17 years. Ninety seven percent (97%) of the participants reported that they received service as per their expectation and were satisfied with the service of the facilities. Major factors for satisfaction were: thorough eye examination (54%), behavior of health staff (40%), and cleanliness of health facility (39%). Another eighty percent (80%) of the participants mentioned that they would recommend or return to the same facility. Fifteen percent of the participants perceived that they faced problems at the eye facility because of their gender. Around three quarters (73%) paid health expenses from their pocket. Most (83%) of the participants rated user fees as either reasonable or inexpensive. CONCLUSION: The majority of participants reported receiving service as expected and willingness to return to the same eye health facility for future consultation. However, most participants had to pay the health care expenses out-of-pocket.

Continuous Knowledge Translation in Action: Designing a Programmatic Research Trial for Equitable Eye Health for Rural Nepalese Women.

Reaching vulnerable populations through programmatic eye health interventions requires a focus on not only the intervention strategies, but the adaptability of the program design process itself. Knowing who is left behind and why solutions that will be effective on the ground at the time of implementation are not necessarily generated. There is a need for eye health programmatic design processes that can trial interventions and allow for continuous knowledge translation along the way. In rural Nepal, women are impacted by multiple and interconnected determinants of health, as well as unique barriers to accessing information and services, requiring targeted programming strategies. This article describes a programmatic design and knowledge translation process that aims to increase women's uptake of eye health services in rural Nepal. The article outlines key learnings of this knowledge translation process, and how this may contribute to addressing gender equity in eye health.

Comparison of early versus standard timing for silicone stent removal following External Dacrocystorhinostomy under local anaesthesia.

INTRODUCTION: The first line treatment for nasolacrimal duct obstruction (NLDO) is external dacrocystorhinostomy (DCR). Following DCR, patients are required to return to Tilganga Institute of Ophthalmology (TIO) six weeks postoperatively for the removal of a silicone stent. As the majority of patients travel large distances at significant cost to reach TIO, most often patients remain within Kathmandu during this six weeks interval. This places a large financial burden on patients. METHODS: A randomized controlled trial was designed to compare patient outcomes after early (two weeks postoperatively) versus standard (six weeks postoperatively) removal of silicone stents. 50 selected patients were randomized into two equal groups. RESULTS: At the time of publication, 31 patients (14 in group A and 17 in group B) had completed three months follow up. A success rate of 92.9% was noted in Group A and a success rate of 94.1% observed in group B. No significant difference was found between the two groups for success rate and rate of complications. CONCLUSION: Early tube removal post DCR appears to cause no significant difference in outcome or complication rates compared to standard tube removal.

Constructing Item Banks for Measuring Quality of Life in Refractive Error.

SIGNIFICANCE: Existing patient-reported outcome instruments in refractive error are paper-based questionnaires. They are not comprehensive and psychometrically robust. This study has identified the content of the refractive error-specific item banks that aim to provide comprehensive and scientific measurement of refractive error-specific quality of life. PURPOSE: The purpose of this study was to identify minimally representative, optimally informative, and efficient sets of items for measuring quality of life in people with refractive error. METHODS: First, items were identified from existing patient-reported outcome instruments. Second, items were developed from qualitative studies with people with refractive error (48 and 101 in-depth interviews in Australia and Nepal, respectively). Third, classification and selection of items were done based on a set of systematic criteria using an iterative process of binning and winnowing. The resulting items underwent cognitive testing with people with refractive error in Australia and in Nepal. Each step was guided by an expert panel consensus. RESULTS: We retrieved 792 items from the existing patient-reported outcome instruments. From the interviews conducted in Australia, a total of 2367 comments were coded into 807 initial items. Similarly, from the interviews conducted in Nepal, 3477 comments were coded into 914 initial items. After binning and winnowing, followed by cognitive testing, a final set of items comprising 337 items for the Item-pool (Australia) and 308 items for the Item-pool (Nepal), both spanning 12 domains, was obtained. Forty-seven percent of items were common across the two item pools. In the Item-pool (Nepal), 65% items were common for corrected and uncorrected refractive error. CONCLUSIONS: We identified the content of two different sets of item banks to comprehensively measure the impact of refractive error on quality of life for people in Australia and Nepal, which may be applicable to high-income country settings and low- and middle-income country settings, respectively. Future work aims to develop computer-adaptive testing system to administer the item banks, resulting in useful measurement tools for researchers, clinicians, and policy planners.

Uncorrected and corrected refractive error experiences of Nepalese adults: a qualitative study.

PURPOSE: The aim of this study was to explore the impact of corrected and uncorrected refractive error (URE) on Nepalese people's quality of life (QoL), and to compare the QoL status between refractive error subgroups. METHODS: Participants were recruited from Tilganga Institute of Ophthalmology and Dhulikhel Hospital, Nepal. Semi-structured in-depth interviews were conducted with 101 people with refractive error. Thematic analysis was used with matrices produced to compare the occurrence of themes and categories across participants. Themes were identified using an inductive approach. RESULTS: Seven major themes emerged that determined refractive error-specific QoL: activity limitation, inconvenience, health concerns, psycho-social impact, economic impact, general and ocular comfort symptoms, and visual symptoms. Activity limitation, economic impact, and symptoms were the most important themes for the participants with URE, whereas inconvenience associated with wearing glasses was the most important issue in glasses wearers. Similarly, possibilities of having side effects or complications were the major concerns for participants wearing contact lens. In general, refractive surgery addressed socio-emotional impact of wearing glasses or contact lens. However, the surgery participants had concerns such as possibility of having to wear glasses again due to relapse of refractive error. CONCLUSION: Impact of refractive error on people's QoL is multifaceted. Significance of the identified themes varies by refractive error subgroups. Refractive correction may not always address QoL impact of URE but often add unique QoL issues. This study findings also provide content for developing an item-bank for quantitatively measuring refractive error-specific QoL in developing country setting.

Microbiological profile of corneal ulcer cases diagnosed in a tertiary care ophthalmological institute in Nepal.

BACKGROUND: Corneal ulcer, a major cause of monocular blindness in developing countries has consistently been listed as the major cause of blindness and visual disability in many of the developing nations in Asia, Africa and the Middle East, ranking second only to cataract. This study was carried out to determine the microbiological profile of corneal ulcer cases diagnosed among patients visiting Tilganga Institute of Ophthalmology (TIO), Nepal. METHODS: A total of 101 corneal scrapping samples were tested for routine culture and antibiotic susceptibility at the pathology department of TIO Nepal from April to October 2014. Microorganisms were identified by using standard microbiological procedures following the manual of American Society for Microbiology (ASM) and their antibiotic susceptibility test, performed by Kirby-Bauer disc diffusion method in conformity with the CLSI guideline. RESULTS: Out of 101 samples analyzed, 44.6% (45/101) showed positive growth with bacterial isolates i.e., 56% (25/45), more prevalent than fungus i.e., 44% (20/45). Among bacteria Streptococcus pneumoniae (31.1%, N = 14) was isolated in highest number whereas Fusarium (13.4%, N = 6) was the most common fungus species. Pseudomonas aeruginosa was the only Gram negative bacteria isolated from corneal ulcer cases. All bacterial isolates were found to be susceptible to the quinolone group of antibiotics (moxifloxacin followed by ofloxacin and ciprofloxacin). CONCLUSIONS: These findings showcase the current trend in the microbiological etiology of corneal ulcer in Nepal, which have important public health implications for the treatment as well as prevention of corneal ulceration in the developing world.

Factors associated with childhood ocular morbidity and blindness in three ecological regions of Nepal: Nepal pediatric ocular disease study.

BACKGROUND: Nepal Pediatric Ocular Diseases Study is a three year longitudinal population based study. Here we present the baseline survey report which aims to investigate various risk factors associated with childhood ocular morbidity and blindness in three ecological regions of Nepal. METHOD: This baseline survey is a population based cross sectional study. The investigation was conducted in a district from each of the following regions: Terai, Hill and Mountain. The Village Development Committees (VDCs) from each district were selected by random sampling. Three Community health workers were given training on vision screening and identification of abnormal ocular signs in children. They conducted a house to house survey in their respected districts examining the children and gathering a standardized set of data variables. Children with abnormal vision or ocular signs were then further examined by pediatric ophthalmologists. RESULTS: A total of 10950 children aged 0-10 years (5403 from Terai, 3204 from the hills, 2343 from the mountains) were enrolled in the study. However 681 (6.2%) were non responders. The male to female ratio was 1.03. The overall prevalence of ocular morbidity was 3.7% (95% CI of 3.4%-4%) and blindness was 0.07% (95% CI of 0.02%-0.12%). Ocular morbidity was more prevalent in the mountain region whereas blindness was more prevalent in the Terai region.Children from the Terai region were more likely to suffer from congenital ocular anomalies compared to the other regions. Children whose mother smoked, drank alcohol, or was illiterate were significantly afflicted with ocular diseases (p < 0.05). In addition,a higher prevalence of ocular disease was related to children with past medical history of systemic illnesses, abnormal postnatal period or missing childhood vaccinations. Blindness was more prevalent in children who suffered from a systemic illness. Females and under-nourished children were more likely to have ocular morbidity and blindness. CONCLUSION: It was found that childhood blindness was more prevalent in the Terai region, the undernourished, females and in those with co-morbid systemic illnesses. This study strongly suggests that prevention of childhood blindness requires additional resources to address these disparity.

Health literacy of common ocular diseases in Nepal.

BACKGROUND: Poor health literacy is often a key cause of lack of or delayed uptake of health care services. The aim of this study was to assess the health literacy of common ocular diseases, namely cataract, glaucoma, night blindness, trachoma and diabetic retinopathy in Nepal. METHODS: A cross sectional study of 1741 participants randomly selected from non-triaged attendants in the outpatient queue at Tilganga Institute of Ophthalmology, a semi urban general population of Bhaktapur district of Kathmandu Valley and patients attending rural outreach clinics. Participants responded to trained enumerators using verbally administered, semi structured questionnaires on their awareness and knowledge of cataract, glaucoma, diabetic retinopathy, night blindness, and trachoma. RESULTS: The awareness of cataract across the entire sample was 49.6%, night blindness was 48.3%, diabetic retinopathy was 29%, glaucoma was 21.3% and trachoma was 6.1%. Patients presenting to rural outreach clinics had poorer awareness of cataract, glaucoma, diabetic retinopathy, night blindness and trachoma compared to those from a semi-urban community and an urban eye hospital (p<0.05), Old age was directly associated with poorer awareness of cataract, glaucoma, night blindness, trachoma and diabetic retinopathy (p<0.05). Female gender was associated with lower awareness of cataract, glaucoma, night blindness and trachoma (p<0.05). Literacy was associated with greater awareness of cataract, glaucoma, diabetic retinopathy, night blindness and trachoma (p<0.05). Higher education was significantly associated with greater awareness of cataract, night blindness and trachoma (p<0.05). Multivariate analysis found that the awareness of common ocular diseases was significantly associated with level of education (p<0.05). Similarly, awareness of cataract, glaucoma, trachoma and night blindness was associated with female gender (p<0.05) whereas awareness of cataract, night blindness, trachoma and diabetic retinopathy was associated with age (p<0.05) but the awareness glaucoma and diabetic retinopathy was associated with camps. CONCLUSIONS: Low awareness of common ocular conditions is associated with factors such as female gender, old age, lower levels of education and rural habitation. A would be successful health promotion programs should specifically target health determinants to promote health literacy and to ensure timely utilization of eye care services.

Patient's perception towards the eye health care system in a tertiary eye care centre in Nepal.

This study was performed to determine patient's perceptions towards eye health care systems in a tertiary eye care center in Nepal. Subjects were randomly selected from the outpatient department of Tilganga Eye Centre (TEC), a tertiary eye care center in Kathmandu, Nepal. The study was performed in April 2003 with 54 patients responding to several questions concerning their satisfaction of the eye care process. Over 40 (74.1%) of the respondents expressed overall satisfaction with the service provided by the hospital staff, and 4 (7.4%) were not satisfied. In addition, a total of 40 (74.1%) respondents were dissatisfied with the extended waiting time for eye examinations and other ocular services, while 7 (13.0%) were satisfied. The study shows that the majority of patients who are treated at Tilganga Eye Centre have positive feelings about Tilganga and its service system. Some processes, however, could be altered or improved to augment the overall quality of patient care.

Microbiology of dacryocystitis among adults population in southern Australia.

Retrospective study on microbiology of dacryocystitis cases in adults was carried out at the Royal Victorian Eye and Ear Hospital (RVEEH). Sixty-four consecutive cases seen between March 2000 and June 2003 were included. Seventy-nine organisms were isolated from the sixty-six samples (1.2/specimen). Aerobic or facultative bacteria were recovered in 76 (96.2), fungi from two specimens (2.5%). And anaerobic bacteria from only one specimen (1.3%). Staphylococcus aureus (27), was most common followed by Pseudomonas aeruginosa (6), Proteus mirabilis (4), Hemophilus parainfluenza (4) and H. influenza (4). Fifty-four samples showed single organism while 12 samples showed multiple organisms. Overall, Gram-positive organisms were predominating (54.4%) over Gram negative (41.8%) organisms. The current bacteriology of lacrimal duct obstruction in the population served by the RVEEH should be taken into account while selecting first line antimicrobial treatment for dacryocystitis and in prophylaxis in lacrimal drainage surgery.

Treatment of vitreoretinal disorders in the developing world: indications and outcomes of vitreoretinal surgery in Nepal.

PURPOSE: To examine the outcomes of vitreoretinal surgery for retinal disorders at Tilganga Eye Centre in Kathmandu, Nepal. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Records of 255 patients undergoing vitreoretinal surgery from December 2000 to January 2003 were reviewed. METHODS: Demographics, diagnoses, duration of symptoms, vision, and examination findings were noted before and after vitreoretinal surgery. MAIN OUTCOME MEASURES: Postoperative data were categorized by surgery type and analyzed by anatomic success, symptoms, and visual acuity (VA). RESULTS: Sixteen percent of patients had >6/60 vision preoperatively, and the mean duration of vision loss before presentation was 4.9 months. Major indications for surgery were retinal detachment (RD) (75%) and vitreous hemorrhage (19%). Anatomic success was achieved in 74.5% of patients. Postoperatively, 39% of patients experienced improved VA, with 33% obtaining >6/60 vision. CONCLUSIONS: Despite prolonged duration of vision loss at presentation, vitreoretinal surgery in the developing world can restore useful vision in many patients with RD and vitreous hemorrhage.

Acute hemorrhagic conjunctivitis epidemic--2003 in Nepal.

This rapid communication present the findings of nationwide outbreak of acute hemorrhagic conjunctivitis (AHC) epidemic occurred in Nepal during summer 2003. Only ten percent of samples showed bacterial and no fungus were grown. On the contrary, viruses were detected in 60.0% cases studied. Of the viruses detected, Adenovirus (ADV), Coxsackie virus (CA24v) and both accounted for 83.3% (30/36), 11.1% (4/36) and 5.5% (2/36), respectively. Interestingly, ADV was detected also from one of the ten a Rupees bill.
