Cost-Effectiveness Analysis of a Regional Program for Identifying and Treating Children with Correctable Refractive Error in Indonesia.

PURPOSE: Indonesia is a rapidly growing county with over 262 million inhabitants, but among highly populated countries it has one of the lowest concentrations of eye care providers. This study evaluated the cost-effectiveness of a program implemented in South Sulawesi, Indonesia that trained school teachers to conduct vision screenings, organized in-school evaluations by opticians, and provided free eyeglasses to school children with refractive error (RE). METHODS: Schoolteachers across 6 districts in South Sulawesi were trained to screen children with possible RE for subsequent evaluation by opticians. All costs associated with designing and implementing the program (administration, training personnel, labor, service delivery, etc.) were assessed. Expenditures and outcomes data were utilized to calculate the cost per disability-adjusted-life-year (DALY) averted using both 2010 and 2016 Global Burden of Disease (GBD) weights. RESULTS: 521 teachers screened 41,212 students across 172 schools in South Sulawesi. 4,506 (10.9%) students failed screening, 2,652 were seen by optometrists, and 2,038 received glasses.The total program cost was US$97,380, with glasses (39.6%) and labor (23.3%) accounting for the two biggest expenditures. In districts with school-based refraction services, the costs per student screened, refracted, and receiving glasses were $2.57, $31.33, and $41.40, respectively; costs were $2.04, $59.80, and $73.22 when district services were instead provided centrally. The estimated cost per DALY averted was US$89.04 based on GBD 2010 weights. CONCLUSION: Treating children with correctable RE in limited resource settings can be done cost-effectively through a school-based model.

Trends in Diabetic Retinopathy, Visual Acuity, and Treatment Outcomes for Patients Living With Diabetes in a Fundus Photograph-Based Diabetic Retinopathy Screening Program in Bangladesh.

Importance: Diabetic retinopathy (DR) is the leading cause of low vision among working-age adults. An estimated 6.9 million people in Bangladesh were living with diabetes in 2017, which is projected to increase to more than 10 million people in 2025. Currently, no standardized and/or large-scale DR screening program exists in Bangladesh. Objective: To develop a novel fundus photograph-based eye screening model for early detection of DR to prevent vision loss in Bangladeshi individuals with diabetes. Design, Setting, and Participants: In this cross-sectional study, 49 264 patients with diabetes underwent opportunistic eye screening at 2 eye hospitals and 1 diabetic hospital in Bangladesh between June 1, 2010, and September 30, 2017. The data set was analyzed from April 8 to December 30, 2018. Technicians were trained to obtain 2-field digital fundus photographs and to grade each according to a standardized DR severity scale. Each patient was counseled and triaged for treatment using defined DR referral criteria. Main Outcomes and Measures: Primary DR grading outcomes, visual acuity, and treatment outcomes. Results: A total of 49 264 patients (54.3% male; mean [SD] age, 50.8 [12.3] years) underwent DR screening during a 7-year period. The DR prevalence rate across all 3 sites was 33% (95% CI, 33%-33%). Prevalence rates varied by center (Chittagong, 64.6% [95% CI, 64.0%-65.0%]; Dhaka, 39.8% [95% CI, 39.0%-41.0%]; and Feni, 13.0% [95% CI, 13.0%-14.0%]). Across all age groups, male patients were at higher risk of prevalent DR than female patients (odds ratio, 1.99; 95% CI, 1.90-2.07). The prevalence was 3.9% for preproliferative DR, 7.8% for proliferative DR, and 19.2% for maculopathy. Individuals with DR had significantly worse visual acuity than those with no DR (best-corrected visual acuity, 0.35 vs 0.21 logMAR; P < .001). The rate of moderate visual impairment was 12.2%, and the rate of blindness was 2.5%. Primary treatments included laser photocoagulation (n = 1637), intravitreal injection (n = 1440), and vitrectomy (n = 309). Conclusions and Relevance: Screening Bangladeshi individuals known to have diabetes using fundus photography identified large numbers of patients with sight-threatening proliferative DR, maculopathy, and visual impairment or blindness. Expansion of eye screening services in Bangladesh is warranted as part of a national government eye care and diabetes health policy.

Uncorrected refractive error and presbyopia among junior high school teachers in Jakarta, Indonesia.

PURPOSE: To report on the frequency of observed refractive and accommodative errors among junior high school teachers in Jakarta, Indonesia, who participated in a Helen Keller International screening, refraction and spectacle distribution program. METHODS: A total of 965 teachers from 19 schools were eligible for screening; those with uncorrected distance visual acuity (VA) ≤ 6/12-3 and teachers ≥ 35 years old with uncorrected end-point print size >Jaeger (J) 6 were referred. Autorefraction and subjective refraction were performed for teachers with confirmed decreased VA. Refractive error was considered present if sphere ≤-0.75 diopters (D), sphere ≥+0.25D or cylinder ≤-0.50 D resulted in ≥ 2 lines of improvement in VA. Presbyopia was considered present if an end-point print size >J6 improved by ≥ 1 optotype with the use of a lens ≥+1.00 D. RESULTS: Overall, 866 teachers were screened (89.7% of those eligible) with complete screening data available for 858 (99.0%), among whom 762 failed screening. Distance refraction data were available for 666 of 762 (87.4%) and near refraction data for 520 of 686 (75.8%) teachers who failed screening. Of those screened, 76.2 ± 9.0% of teachers had refractive and/or accommodative error and 57.1 ± 7.6% had uncorrected refractive and/or accommodative error. Overall and uncorrected distance refractive error affected 44.2 ± 3.7% and 36.0 ± 3.6%, respectively; overall and uncorrected presbyopia affected 66.4 ± 8.1% and 41.0 ± 6.6%, respectively. CONCLUSION: As defined in this program, refractive and accommodative errors were common among teachers in Jakarta.
