Methods for a population-based Comprehensive Eye care Workload Assessment (CEWA) study in Southern India

Eye care programs, in developing countries, are often planned using the prevalence of blindness and visual impairment, often estimated from Rapid Assessment of Avoidable Blindness (RAAB) surveys. A limitation of this planning approach is that it ignores the annual overall eye care requirements for a given population. Moreover, targets set are arbitrary, often influenced by capacity rather than need. To address this lacunae, we implemented a novel study design to estimate the annual need for comprehensive eye care in a 1.2 million populations. We conducted a population-based longitudinal study in Theni district, Tamil Nadu, India. All permanent residents of all ages were included. We conducted the study in three phases, (i) household-level enumeration and enrollment, (ii) basic eye examination (BEE) at household one-year post-enrollment, and (iii) assessment of eye care utilization and full eye examination (FEE) at central locations. All people aged 40 years and above were invited to the FEE. Those aged <40 years were invited to the FEE if indicated. In the main study, we enrolled 24,327 subjects (58% aged below 40 years and 42% aged 40 years and above). Of those less than 40 years, 72% completed the BEE, of whom 20% were referred for FEE at central location. Of the people aged ?40 years, 70% underwent FEE. Our study design provides insights for appropriate long-term public health intervention planning, resource allocation, effective service delivery, and designing of eye care services for resource-limited settings.

The effect of social determinants of health on severity of microbial keratitis presentation at a tertiary eye care hospital in Southern India

Purpose: Understanding the association between social determinants of health (SDoHs) and microbial keratitis (MK) can inform underlying risk for patients and identify risk factors associated with worse disease, such as presenting visual acuity (VA) and time to initial presentation. Methods: This was a cross?sectional study was conducted with patients presenting with MK to the cornea clinic at a tertiary care hospital in Madurai, India. Patient demographics, SDoH survey responses, geographic pollution, and clinical features at presentation were collected. Descriptive statistics, univariate analysis, multi?variable linear regression models, and Poisson regression models were utilized. Results: There were 51 patients evaluated. The mean age was 51.2 years (SD = 13.3); 33.3% were female and 55% did not visit a vision center (VC) prior to presenting to the clinic. The median presenting logarithm of the minimum angle of resolution (logMAR) VA was 1.1 [Snellen 20/240, inter?quartile range (IQR) = 20/80 to 20/4000]. The median time to presentation was 7 days (IQR = 4.5 to 10). The average particulate matter 2.5 (PM2.5) concentration, a measure of air pollution, for the districts from which the patients traveled was 24.3 ?g/m3 (SD = 1.6). Age? and sex?adjusted linear regression and Poisson regression results showed that higher levels of PM2.5 were associated with 0.28 worse presenting logMAR VA (Snellen 2.8 lines, P = 0.002). Patients who did not visit a VC had a 100% longer time to presentation compared to those who did (incidence rate ratio = 2.0, 95% confidence interval = 1.3–3.0, P = 0.001). Conclusion: Patient SDoH and environmental exposures can impact MK presentation. Understanding SDoH is important for public health and policy implications to mitigate eye health disparities in India.

Compliance with follow-up in patients with diabetic macular edema: Eye care center vs. diabetes care center

Purpose: The study was conducted to compare the compliance to intravitreal injection treatment and follow?up in patients with center?involving diabetic macular edema (CI?DME) and treatment outcomes between a tertiary eye care facility and a tertiary diabetes care center. Methods: A retrospective review was conducted on treatment naïve DME patients who had received intravitreal anti?vascular endothelial growth factor (anti?VEGF) injections in 2019. Participants were people with type 2 diabetes who were under regular care at the eye care center or the diabetes care center in Chennai. The outcome measures were noted at months 1, 2, 3, 6, and 12. Results: A review of 136 patients treated for CI?DME (72 from the eye care center and 64 from a diabetes care center) was carried out. The severity of diabetic retinopathy (DR) was similar in both centers. There was no statistically significant (P > 0.05) difference in the choice of initial intravitreal drug in the two centers. At 12?month follow?up, only 29.16% came for a follow?up in the eye center vs. 76.56% in a diabetes care center (P = 0.000). The multivariate logistic regression showed increasing age was associated with non?compliance in both the groups (eye care center: odds ratio [OR] 0.91; 95% confidence interval [CI] 0.82–1.21; P = 0.044) and diabetes care center (OR 1.15; 95% CI 1.02–1.29; P = 0.020). Conclusion: The follow?up rate between eye care and diabetic care center with DME showed a significant disparity. By providing comprehensive diabetes care for all complications under one roof, compliance with follow?up can be improved in people with DME

Mumbai metropolitan region eye care facility survey: Mumbai Eye Disease Study (MEDiS) report #1

Purpose: To examine the eye care practice in the Mumbai Metropolitan Region (MMR). Methods: This study consisted of primary and secondary research conducted in five zones of MMR. The primary research included interviews with the patients, eye care providers, and key opinion leaders. The secondary research included analyzing data from the professional ophthalmology societies, public health domain, and health insurance providers. We divided people into three economic classes by annual income – low (<INR 0.3 m), middle (INR 0.31–1.8 m), and high (>1.8 m). We analyzed the collected data to estimate the eye care demand– supply, quality of eye care, health?seeking behavior, gap in eye care delivery, and eye care expenditure. Results: We examined 473 key eye care facilities and interviewed 513 people. The ophthalmologist density in MMR was 80/million, and it was the highest in North MMR. Most ophthalmologists visited several facilities. Cataract surgery and glaucoma care coverage were better than other specialties; it was poor for oncology and oculoplastic services. Annual eye examination practice was poor in the low? and middle?income groups than in the high?income group (48%–50% vs. 85%). Most people preferred visiting eye care facilities within 5 km of their residence. Out?of?pocket spending was between 60% and 83%. Lower?income group people preferred public facilities. Conclusion: MMR eye care needs further improvement in affordable and accessible eye care, health literacy, public health surveillance, research into the application of newer technologies to provide less?expensive home care for the elderly and minimize their hospital visits, and collection and analysis of big data to address city?specific eye health issues.

Primary eye care in pediatric population-I study (PREPP-I study): Demographic and clinical profile of pediatric patients treated in six major vision centers of a tertiary eye care facility in South India

Purpose: The study intends to evaluate the demographic and clinical profile of pediatric patients (0–18 years) attending six vision centers (VCs) of a tertiary eye care facility in south India. Methods: This is a cross?sectional observation study conducted at six major peripheral VCs of a tertiary eye care facility in South India from June 20 to Dec 20. All children presenting at the VCs under a base hospital (BH) in Pondicherry, whose parents gave consent were included. Data were entered by the ophthalmic assistants in the VC and cross checked by the principal investigator at the BH. Results: A total of 250 pediatric patients were brought to the VCs during the study period, predominantly males (60.8%), with a mean age of 8.2 ± 4.5 years (0– 18 years). Half of them were staying within 5 km from the VCs. Most children were escorted by their parents (88%), and the expenditure of travel to the VC was affordable for most of the parents (75%). Also, 53.6% of patients were in their primary school, while schooling had not started for 28% of children. Visual acuity (VA) could be assessed only for school?going children and older children due to lack of age?matched VA assessment tools. Most children (91.3%) had uncorrected VA better than or equal to 6/18 in the better eye, and approximately 3% had VA worse than 6/60. All patients had best corrected VA of 6/6–6/18 after cycloplegic refraction. Most children reported to the VC for allergic conjunctivitis (25%), followed by refractive error (13%) and squint (10.4%). Urgent referral to the BH was made for 47 children. Conclusion: Primary eye care in pediatric population?I (PREPP?I) showed that most children can be treated at the VCs and only one?fifth of the children require active intervention at higher referral centers. Further study on satisfaction of services provided for pediatric patients in these VCs and barriers of not reporting to the BH when referred are considered for the PREPP?II study

Uptake pattern of training programs over two decades at an International Ophthalmic Training Institute in India

Purpose: Inadequacy of trained human resources is a critical challenge for eye?care delivery worldwide. Recognizing this, the World Health Organization (WHO) and the International Agency for Prevention of Blindness had identified the development of human resources as one of the focal areas in the global initiative “Vision 2020: The Right to Sight.” The global action plan of the WHO also emphasized the need for trained workforce for ensuring comprehensive eye?care services. We aimed to present the uptake pattern of training programs offered at a high?volume training institute in India. Methods: We did a retrospective analysis of data related to training programs conducted between 2000 and 2019. Trainees included ophthalmologists, allied ophthalmic personnel, and eye?care management professionals from all over the world. We analyzed the overall growth over the 20 years in the WHO regions. The uptake patterns were also analyzed across four segments of 5?year?periods by the type of training. Results: Overall, 9091 trainees from 118 countries attended training in over 40 courses that included long? and short?term clinical training for ophthalmologists (54.2%) and short?term training for eye?care managers (29.5%), allied ophthalmic personnel (6.2%), and eye?care technicians (10.2%). The majority of the trainees (81.3%) came from the Southeast Asian region, of which 87.4% were from India. Most (98.3%) of the trainees belonged to developing countries. We found an overall average growth of 4.8% in the training uptake across the four 5?year segments over the 20 years. Conclusion: Comparatively better representation of trainees from the developing countries is encouraging as the prevalence of blindness and visual impairment is higher in those countries, warranting improved eye?care delivery. Given the strong influence of distance and associated costs of accessing training, the development of similar institutes in other regions might help enhance the global efforts to eliminate needless blindness.

Knowledge and Attitude of Commercial Drivers in Benin City towards Utilization of Eye Care Services

Background: An excellent vision is crucial in driving and many driving related injuries and fatalities have been associated with visual problems especially for commercial drivers. Visual efficiency plays an important role during driving. This study determined the knowledge and attitude of commercial drivers in Benin towards utilization of eye care services. Method: This was a cross sectional study conducted among 100 commercial drivers in Benin City metropolis. Data was collected using an interviewer administered questionnaire, among commercial drivers from 3 major parks in Benin City. Data was analyzed using SPSS version 22. Descriptive and inferential statistics was used to analyze the data. Statistical significance was set at p < 0.05. Results:The results revealedthat majorityofcommercial drivers in Benin city had knowledge of which an eye care provider is (60%), as well as knowing the eye care providers closest to them. However, 75% of them do not see it necessary to utilize the eye care services. Results of this study will help eye care professionals to better advise commercial drivers, concerning their eye health.Conclusion: Findingsrevealed that commercial drivers had a good knowledge of whom eye care providers are but a poor level of utilization of eye care services that they provide (P< 0.05). The factors affecting the poor utilization of eye care services was not statistically significant.

Eye care utilization among older subjects with visual impairment in Northwest Ethiopia

Purpose: To find out the level of eye care service utilization and its determinants among the elderly visually impaired populations while visiting ophthalmic outreach locations in North Western Ethiopia, 2021. Methods: An ophthalmic outreach-based cross-sectional study was conducted on 852 visually impaired older people. Participants were selected by using a systematic random sampling method from January to July 2021. Data were collected by using an interviewer-administered questionnaire and an ocular examination. The collected data were entered into the Epi Info 7, and analyzed using SPSS 20. A binary logistic regression was fitted. Results: A total of 821 participants, with a response rate of 96.5%, were included in the study. The utilization of eye care services within the past two years prior to the study was 21.1% (95 % CI: 18.2­23.9). Having systemic disease (AOR = 3.2, 95% CI: 1.5­7.0), being a spectacle wearer (AOR = 4.5, 95% CI: 2.0­9.4), having visual impairment at distance (AOR = 2.9; 95% CI: 1.5­5.6), being blind (AOR = 2.9; 95% CI: 1.5­5.6), duration of visual impairment ≤1 year (AOR = 2.5; 95% CI: 1.3­4.9) were all significantly associated. Conclusion: In this study, utilization of eye care services was low. Being visually impaired at distance, being blind, recent onset of visual impairment, being a spectacle wearer, and having systemic disease were all related to the use of eye care services. The commonest barriers to utilization of eye care services were financial scarcity and long distances between eye care facilities.

Botulinum Toxin For Treatment Of Migraine Headaches - A Study From Tertiary Eye Care Centre

Background - Migraine is one of the common causes of recurrent headaches. Botulinum toxin type A (Botox®) is a neurotoxin produced by Clostridium botulinum that paralyzes nerves. The purpose of this study was to evaluate the efficacy of pericranial Botox® administration in migraine headache in patients attending a tertiary eye care centre. Method - A prospective, non-randomized study consisting of 54 patients was performed. Subjects were candidates who either sought Botox® treatment for hyperfunctional facial lines with concomitant headache or candidates for Botox® treatment specifically for headaches. Headaches were classified based on International Headache Society criteria. Botox® was injected into the glabellar, temporal, frontal, and/or suboccipital regions of the head and neck. Patients were treated every three months, with a maximum of three sessions. Botox dosage ranged from 75 - 155 Units per patient. Main outcome measures were relief from migraine headache symptoms, reduction of headache severity and duration of symptom free period. Age ranged from 18 to 65 (mean 34.6±6.5) years. Among 54 subjects treatedResults - prophylactically, complete response (symptom elimination) was noted in 31 (57.40%) with a mean {Standard deviation – (SD)} response duration of 4.3 (2.4) months; 16 (29.62%) reported partial response (?50% reduction in headache frequency or severity) with a mean (SD) response duration of 2.5 (1.7) months. 7 (12.96%) reported no response. No systemic adverse effects were reported. Botox® is found to be a safe and effective therapy for prophylacticConclusion - treatment of migraine.

Eye care seeking behavior among rural adults in South India: Tamil Nadu Rural Eye Examination (TREE) Study Report 1

Purpose: To present the eye care seeking behavior among rural adults in South India. Methods: This cross?sectional study was conducted between 2019 and 2020 covering three blocks of the Thiruvannamalai district, Tamil Nadu, India. Door?to?door survey was performed to collect demographic information, status of literacy, occupation, and details of previous eye examination. Distance visual acuity was tested for individuals available in the house using a log MAR (logarithm of minimum angle of resonance) chart. Association between demographic details, details of previous eye examination, and status of vision was analyzed using logistic regression. Results: A data of 12,913 individuals were included for the analysis, of which 6460 (50.03%) were females. Of the total individuals, 2007 (15.54%) had undergone an eye examination previously. There were 1639 (28.50%) people who had a vision less than 0.2 log MAR in at least one eye. The odds of reported ‘previous eye examination’ were more among females [odds ratio (OR) 1.48, 95% confidence interval (CI): 1.32–1.66, P < 0.001]; individuals aged above 60 years [OR: 11.46, 95% CI: 9.44–13.91, P < 0.001], between 40 and 60 years [OR: 10.43, 95% CI: 8.85–12.30, P < 0.001], and between 18 and 40 years [OR: 2.48, 95% CI: 2.16–2.84, P < 0.001]; illiterates (OR: 1.76, 95% CI: 1.45–2.15, P < 0.001); and farmers (OR: 1.32 95% CI: 1.12–1.55, P = 0.001). Conclusion: The study presents the utilization of eye care among rural South Indian adults. Almost 84.46% of individuals had not undergone any eye examination. Robust measures to promote eye care management would help in effective utilization of eye care services among rural adults.

Effect of Integrated People-Centred Eye Care (IPEC) Model on Eye Care Seeking Behaviour of Community

Background: World report on vision makes integrated people-centered eye care as care model of choice. Integrating eye care with the existing public health system makes services available, accessible, affordable, and sustainable. Being from the community, Accredited Social Health Activists(ASHAs) are better suited to improve people’s eye health-seeking behavior. Objectives: This study aims to assess the eye care-seeking behavior of community and to understand their response toward the approach of integrated vision centers (VC) with ASHA involvement. Methods: A cross-sectional descriptive study was conducted in South Delhi district where integrated VC were functional for more than a year. These centers were supervised by medical officer in?charge, under whom ophthalmic assistants, ASHAs, auxiliary nurse midwives, and pharmacist work. ASHAs were trained in community-based primary eye care. The community survey was conducted on eye health-seeking behavior and utilization of VC services. Descriptive statistics were used for data analysis. Results: Out of 1571 study participants, 998 reported any ophthalmic illness in family in the past 6 months as against 1302 who reported nonophthalmic illness in family. The majority (1461, 90%) were aware about integrated VC and half of them (748, 51.2%) visited it. Of them, 64.2% were motivated through ASHAs. ASHAs spread awareness about eye diseases, eye treatment facility, and referred patients from the community. The majority (93%) were happy with the integrated VC and 87.8% were happy with ASHAs. Conclusion: Integrated VC with ASHA engagement could pave the way for universal eye health. Understanding people’s needs and engaging community would increase the demand for eye care.

Psychosocial assessment among ophthalmic patients attending tertiary eye care centre during the lockdown in times of COVID-19 pandemic

Purpose: The coronavirus disease (COVID?19) pandemic continues to play havoc in our lives. During the first “ lockdown” in 2020, we were keen on assessing the anxiety levels of patients who sought ophthalmic care despite the lockdown. Public health actions, such as social distancing, were necessary to reduce the spread of COVID?19. As a result, most people felt isolated and lonely, thereby causing increased levels of stress and anxiety in them. We aimed to assess the anxiety levels using the Hamilton Anxiety Scale and personality assessment using the 57?point Eysenck’s Personality Inventory (EPI) questionnaire among patients visiting a tertiary eye care hospital during the lockdown period. Methods: Consecutive patients attending an ophthalmic tertiary care hospital during the COVID?19 pandemic and lockdown were approached to be a part of this prospective cross?sectional survey. Results: In total, 1,088 responses were analyzed during the 2?month study period with the mean age being 45.7 + 16.9 years. The majority had completed graduation (78%) with 15 years or more of formal education. The purpose of the visit was an emergency consultation in 42% (n = 455), a review appointment in 42% (n = 457), and the remaining (16%, n = 176) came for a routine consultation. The majority of the patients (>90%) did not report experiencing any of the 14 sets of symptoms. A mild level of anxiety was noted in 1,086 (>99%) respondents, whereas only 2 (<1%) respondents showed mild–moderate levels of anxiety. Financial concerns such as affordability of medications (6% vs. 3%, P = 0.05) and fear of losing their job (16% vs. 11%, P = 0.02) were significantly more in those experiencing any anxiety compared to those with no anxiety. Conclusion: Our study revealed that patients visiting a tertiary ophthalmic center during lockdown were graduates, sought eye consultation primarily for emergency or a review, and had no major anxiety symptoms. In those with anxiety, the affordability of medicines and loss of jobs were the main concerns.

A study of referral pattern to pediatric ophthalmology department in a tertiary eye-care center of South-India

Purpose: The study was aimed at finding out the present pattern of referrals to the Pediatric Ophthalmology outpatient department (OPD) in a tertiary eye care hospital and thus identify the discrepancy of referral, if any, which would help to modify and enhance the practice guidelines. Methods: The study was conducted by retrospectively collecting data from all referral letters that were already uploaded in the Electronic Medical Report (EMR) against all patients from June 2019 to December 2019. All pediatric patients in the age group of 0–16 years were included in the study. The practicing field of referring clinicians was noted along with the maximum information that could be collected from the referral letter and were thus assessed for the quality, accuracy, and timely referral. Results: Out of 77 referrals received in the study period, six referral letters neither had any mention of the designation of the referring clinician nor any specific diagnosis or details. Thus, only 71 patients were included for further study. The referring clinicians were mainly ophthalmologists, pediatricians, general practitioners (GPs), and others (cardiologists, neurologists). Maximum patients were referred by ophthalmologists (76%) but visual acuity was noted only for 30% of these patients. Almost half of the referral diagnosis was accurate. Pediatrician referrals were found to be more detailed and précised. Conclusion: There is a need for a standardized hospital?specific format of referrals and basic training to primary care providers on some simple tests (Lights reflex tests) for identifying the “red flags” in pediatric eye examination and thus enhancing the quality and timely referral per se

A study to assess the knowledge and skills of Accredited Social Health Activists and its retention after training in community-based primary eye care

Purpose: Community volunteers like Accredited Social Health Activists (ASHAs) could be utilized for linking community and eye care services. Research is needed to effectively utilize them. This study was to assess whether ASHAs could imbibe new knowledge in eye care and conduct vision screening. Methods: Settings and Design: A pre?post?intervention study in South Delhi Integrated Vision Centres. It was conducted from January 2016 to March 2017. One day of conceptual training followed by hands?on training in vision screening was imparted to ASHAs. The knowledge was assessed thrice: before, immediately after, and following 1 year after training. The vision screening skill was assessed twice. Descriptive analysis using percentages, mean and standard deviations. Paired t?test was used for assessing the change in scores. Results: A total of 102 ASHAs were recruited. A significant increase in the knowledge score of ASHAs before (14.96) and after training (25.38) (P < 0.001) was noted. The knowledge score was sustained at 1 year (21.75). The satisfactory skill of vision screening was seen in 88 (86.3%) ASHAs after training, while 79 (77.5%) ASHAs still retained it after 1 year. Conclusion: The potential to involve ASHAs in community?based frontline eye care activities: awareness generation of eye diseases, identification of referrable conditions, and facilitating individuals to seek eye care facilities. This study informs about the duration, frequency, and content of the training. It also provides evidence on the improvement and sustainability of eye care knowledge and skills by ASHAs after conceptual and hands?on training

Introducción de vídeojuegos en el tratamiento convencional de la ambliopía funcional / Incorporation of videogames into the conventional treatment for functional amblyopia

RESUMEN Objetivo: Valorar la efectividad del vídeojuego en educandos que padecen ambliopía funcional. Métodos: Se confeccionó la historia clínica de cada paciente, la cual incluyó la revisión oftalmológica completa, la evaluación de la agudeza visual con la prueba adecuada a cada edad, y se evaluó la presencia de supresión mediante la prueba de filtro rojo y las luces de Worth. Cada prueba se realizó de forma individual según el tipo y la severidad de la ambliopía, y se le indicó la refracción correspondiente. Los pacientes se dividieron en dos grupos: al grupo A se le aplicó la terapia tradicional de la ambliopía, y al grupo B se le siguió la misma pauta que un tratamiento tradicional de ambliopía, pero con la introducción de vídeojuegos. Resultados: Se observó en el grupo A un predominio de los pacientes con agudeza visual inicial entre 0,2 - 0,4 (50 %), la cual se incrementó en dos líneas o más en el (55 %); sin embargo, en el grupo B la agudeza inicial entre 0,2 - 0,4 fue de 56,5 %. Los resultados sensoriales seis meses posteriores al tratamiento, según cada grupo de estudio, mostraron en el grupo B una reducción de la supresión en el 91,3 %, y en el grupo A de un 75 %. Conclusión: La terapia visual combinada con vídeojuego es efectiva; mejora la agudeza visual; elimina y reduce la supresión, por lo que constituye una herramienta que complementa la terapia visual tradicional de la ambliopía.

ABSTRACT Objective: Assess the effectiveness of videogames for students suffering from functional amblyopia. Methods: A clinical record was developed for each patient, which included complete ophthalmological examination, visual acuity evaluation with the suitable test for each age, and determination of the presence of suppression by the red filter test and the Worth lights test. Each test was conducted individually according to the type and severity of amblyopia, and the corresponding refraction was indicated. The patients were divided into two groups: Group A received traditional amblyopia therapy, whereas Group B underwent traditional amblyopia treatment combined with the incorporation of videogames. Results: Group A showed a predominance of patients with initial visual acuity between 0.2 - 0.4 (50%), which increased two lines or more in 55%. However, in Group B initial visual acuity ranged between 0.2 - 0.4 in 56.5%. Six months after treatment, sensory results were 91.3% suppression reduction in Group B and 75% in Group A. Conclusion: Visual therapy proved effective when combined with videogames: visual acuity improved and suppression was reduced. It is thus a suitable tool to complement the traditional visual therapy for amblyopia.

Pattern of ophthalmic referral from primary healthcare centres to secondary and tertiary hospitals in Qassim Province, Saudi Arabia

Background: References of patients with ocular diseases are an indirect indicator that reflects integration of primary eye care into primary health care system. The study reviewed the ophthalmic references from four randomly selected primary health care centres to ophthalmic unit of secondary and tertiary hospitals in Qassim Province of Saudi Arabia.Methods: This was a retrospective health record review study was undertaken at four PHC centres in Qassim region during the year 2017. All cases referred for eye care from January 2015 until December 2016 were included. Prevalence of ophthalmic reference, profile of ophthalmic patients and ophthalmic diagnosis were analysed.Results: From primary health care centres, 423 eye cases from 1,387,996 population of catchment area were referred. The annual prevalence of eye reference was 1.5 per 10,000. Vision screening and diabetic retinopathy evaluation comprised of 55.5% of total reference.Conclusions: Poor reference pattern from primary health care centers to secondary and tertiary eye centre suggest urgent and strong need of implementing primary eye care in the primary health care centres of Saudi Arabia. Referral of simple eye cases are increasing the workload of ophthalmologists and can delay urgent referrals like cases of diabetic retinopathy screening.

Role of teleophthalmology to manage anterior segment conditions in vision centres of south India: EyeSmart study-I

Purpose: To study the role of teleophthalmology (TO) in the diagnosis and treatment of anterior segment conditions (including adnexal conditions) in rural areas. Methods: This is a pilot study of 5,604 patients, who visited primary vision centres (VCs) for 1 week from 1-7 September 2018. The patients were examined by a vision technician (VT) to identify those who may need teleconsultation. The centres were located in 16 districts of four Indian states of Andhra Pradesh, Telangana, Odisha, and Karnataka. The demographic profile, along with the role of teleconsultation was reviewed. Results: Teleconsultation was advised in 6.9% of the patients, out of which 59.6% were referred to a higher level of care, and 40.4% were treated directly at the VC. Teleconsultations were higher among males (7.0% as compared to 6.6% in females), though not statistically significant (P = 0.55). Teleconsultation was higher in the older population, that is, 60 years and above (14.5%); those with severe visual impairment (VI) (21%) and blindness (31.1%); and in the states of Telangana (11%) and Andhra Pradesh (6.3%). It was noted that 45% of the patients who underwent teleconsultation had pathologies related to ocular surface, cornea and lid, and adnexa-related conditions. Conclusion: Teleconsultation has a significant role in the management of anterior segment conditions in bridging the gap between the patients and ophthalmologists in rural India. TO can also play an important role in the diagnosis and management of anterior segment, lid, and adnexa-related pathologies.

Evaluation of a training program on primary eye care for an Accredited Social Health Activist (ASHA) in an urban district

Purpose: An Accredited Social Health Activist (ASHA) available in community could be a potential primary eye care (PEC) worker. Training programme for ASHAs on PEC was undertaken & evaluated in a district of a capital city. Methods: ASHAs selected randomly from a district were imparted one day training on PEC & expected to refer patients to nearby Vision Centres (VC). Their knowledge was assessed before & after training and re-evaluated 1 year later. ASHAs were asked to conduct vision screening of 40+ population in their areas and ASHA referrals were noted by Optometrist in VC. Focus Group Discussions (FGD) of ASHAs were held to find barriers & facilitating factors in engaging ASHAs in PEC. Training was evaluated using Kirkpatrick's evaluation model for measuring reactions, learning, behaviour and results. Results: Mean knowledge score increased from 14.96 (±4.34) pre-training to 25.38 (±3.48) post- training and sustained at 21.75 (±4.16) at 1year. Monthly average OPD of vision centres increased by 23.6% after ASHA training. FGDs revealed that ASHAs were willing to work in eye care for awareness generation and patient facilitation but were hesitant in conducting vision screening. Conclusion: ASHAs can be trained as PEC workers provided they have adequate support.

Primary eye care in India – The vision center model

The World Health Organization (WHO) Global Action Plan (GAP) 2014-19 emphasize providing Comprehensive Eye Care (CEC) using the health system approach to achieve Universal Eye Health Coverage (UEHC). An important aspect of CEC is Primary Eye Care (PEC). The scope of PEC varies significantly with primary health workers providing PEC in most parts of the developing world, whereas in developed nations PEC is provided by specialized personnel such as optometrists. This article focuses on delivery of PEC models in India, specifically through the vision center (VC) approach. VCs are part of a larger eye care network and provide PEC in remote rural areas of the country. The authors describe the how PEC is delivered in more than 300 VCs operated by six mentor hospitals in India under the Global Sight Initiative (GSI). Key factors compared include: The role of leadership; human resource planning, including recruitment and retention; service delivery; leveraging technology for planning and reaching key populations; financial sustainability; supply chain management; and quality and monitoring. It also discusses issues to be considered to strengthen VCs as we move ahead towards our collective goal of achieving UEHC and eliminating avoidable blindness.

Comprehensive eye care - Issues, challenges, and way forward

As we move from a disease-specific care model toward comprehensive eye care (CEC), there is a need for a more holistic and integrated approach involving the health system. It should encompass not only treatment, but also prevention, promotion, and rehabilitation of incurable blindness. Although a few models already exist, the majority of health systems still face the challenges in the implementation of CEC, mainly due to political, economic, and logistic barriers. Shortage of eye care human resources, lack of educational skills, paucity of funds, limited access to instrumentation and treatment modalities, poor outreach, lack of transportation, and fear of surgery represent the major barriers to its large-scale diffusion. In most low- and middle-income countries, primary eye care services are defective and are inadequately integrated into primary health care and national health systems. Social, economic, and demographic factors such as age, gender, place of residence, personal incomes, ethnicity, political status, and health status also reduce the potential of success of any intervention. This article highlights these issues and demonstrates the way forward to address them by strengthening the health system as well as leveraging technological innovations to facilitate further care.
