Résumé
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.
Résumé
In 2020, the global prevalence of glaucoma was estimated to be 76 million and it was projected to increase to 111.8 million by 2040. Accurate intraocular pressure (IOP) measurement is imperative in glaucoma management since it is the only modifiable risk factor. Numerous studies have compared the reliability of IOP measured using transpalpebral tonometers and Goldmann applanation tonometry (GAT). This systematic review and meta-analysis aims to update the existing literature with a reliability and agreement comparison of transpalpebral tonometers against the gold standard GAT for IOP measurement among individuals presenting for ophthalmic examinations. The data collection will be performed using a predefined search strategy through electronic databases. Prospective methods-comparison studies published between January 2000 and September 2022 will be included. Studies will be deemed eligible if they report empirical findings on the agreement between transpalpebral tonometry and Goldmann applanation tonometry. The standard deviation and limits of agreement between each study and their pooled estimate along with weights and percentage of error will be reported using a forest plot. Cochrane’s Q test and the I2 statistic will be used to assess heterogeneity, and the publication bias will be investigated using a funnel plot, Begg’s and Egger’s tests. The review results will provide additional evidence on the reliability of transpalpebral tonometers that, in turn, could possibly assist practitioners to make informed decision about using it as a screening or diagnostic device for clinical practice, outreach camps, or home-based screening.

Résumé
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.
