RESUMO

Según la Organización Mundial de la Salud, la ceguera está definida como la agudeza visual inferior a 3/60 (20/400) en el mejor ojo y un campo visual menor a 10° desde el punto central de fijación. El objetivo de este trabajo fue describir las características clínico demográficas de pacientes con diagnóstico de ceguera irreversible atendidos en el Servicio de Oftalmología General de la Clínica Belén - Coronel Oviedo (Paraguay). Estudio observacional, descriptivo y retrospectivo de corte transversal. Se realizó la revisión retrospectiva de las historias clínicas de los pacientes con diagnóstico de ceguera irreversible atendidos en el Servicio de Oftalmología General de la Clínica Belén, entre el 1 de febrero 2018 y el 28 de febrero 2019. Se analizaron la edad, sexo, escolaridad, procedencia, agudeza visual, comorbilidades y etiología de la deficiencia visual. El análisis estadístico fue mediante el cálculo de frecuencias absolutas y relativas para las variables cualitativas, y el promedio y desviación estándar para las cuantitativas. Se estudiaron 78 pacientes, con predominio del sexo masculino (56,4%), edad de 71 a 95 años (43,6%) y primaria incompleta (41%). La hipertensión arterial (55,6%) fue la principal comorbilidad y glaucoma (43,6%) la etiología de ceguera más frecuente. El glaucoma fue más frecuente en varones que en mujeres (59% vs 32%) y en pacientes mayores de 50 años de edad (50%). En esta serie, los pacientes presentaron ceguera irreversible bilateral, en mayor frecuencia en varones, mayores de 50 años de edad, hipertensión como comorbilidad y glaucoma como etiología más frecuente

According to the World Health Organization, blindness is defined as visual acuity less than 3/60 (20/400) in the better eye and a visual field less than 10 ° from the central fixation point. The objective was to describe the clinical demographic characteristics of patients with a diagnosis of irreversible blindness treated at the General Ophthalmology Service of the "Clínica Belén" - "Coronel Oviedo" (Paraguay). This was an observational, descriptive and retrospective cross-sectional study. A retrospective review of the medical records of patients with a diagnosis of irreversible blindness treated at the General Ophthalmology Service of the "Clínica Belén" between February 1, 2018 and February 28, 2019 was carried out. Age, sex, education, origin, visual acuity, comorbidities and etiology of visual impairment were analyzed. The statistical analysis was through the calculation of absolute and relative frequencies, as well as the average and standard deviation. Seventy eight patients were studied, with a slight predominance of males (56.4%), aged 71 to 95 years (43.6%), incomplete primary school (41%) and from "Coronel Oviedo" (25.6 %) and surroundings. Arterial hypertension (55.6%) was the main comorbidity and glaucoma (43.6%) the most frequent blindness etiology. Glaucoma was more common in male patients than female patients (59% and 32%, respectively) and in patients older than 50 years of age (50%). In this series, patients presented bilateral irreversible blindness, more frequent in men, older than 50 years of age, hypertension as comorbidity and glaucoma as the most frequent etiology

RESUMO

Introducción: Los programas de residencia en Oftalmología juegan un papel fundamental en el entrenamiento de cirujanos en cirugía de cataratas. Un componente fundamental para el desarrollo de competencias en la cirugía de cataratas es contar con un programa estructurado de entrenamiento. Objetivo: Determinar la curva de aprendizaje de cirugía de cataratas con la técnica MSICS (cirugía manual de catarata con incisión pequeña) en residentes de segundo y tercer año en la Fundación Visión entre febrero de 2014 a febrero 2018. Método: Estudio observacional retrospectivo de cohorte, donde se estudiaron todas las cirugías de catarata por MSICS realizadas por los residentes en su segundo y tercer año de residencia. Las variables fueron características demográficas de los residentes, año y semestre de residencia, número y tipo de complicaciones. Resultados: En el periodo de estudio se realizaron 807 cirugías realizadas por cinco residentes entre 27 a 33 años de edad, tres del sexo femenino. El número de cirugía por residente varió entre 122 a 198. La tasa global de complicaciones fue de 23,7%, en el primer semestre fue 58,8%, que se redujo a 15,2% en el cuarto semestre. La ruptura de capsula posterior se presentó en el 7,6% de los casos y la Zonulo dialisis en 1,9%. Conclusión: Se observó una reducción importante en la tasa de complicaciones al terminar el entrenamiento.

Introduction: Ophthalmology residency programs play a fundamental role in the training of surgeons for cataract surgery. A fundamental component for the development of competencies in cataract surgery is having a structured training program. Objective: To determine learning curve of cataract surgery with MSICS (Manual Small-Incision Cataract Surgery) technique in second- and third-year residents at Fundación Visión between February 2014 and February 2018. Method: Retrospective observational cohort study, where all cataract surgeries by the MSICS technique performed by residents in their second and third year of residence were studied. The variables were demographic characteristics of the residents, year and semester of residence, number and type of complications. Results: In the study period 807 surgeries were performed by five residents aged 27 to 33 years, three were female. The number of surgeries per resident ranged from 122 to 198. Overall complication rate was 23.7%, in the first semester it was 58.8%, which decreased to 15.2% in the fourth semester. Posterior capsule rupture occurred in 7.6% of cases and Zonular dialysis 1.9%. Conclusion: A significant reduction in the rate of complications was observed at the end of training.

RESUMO

PURPOSE: To determine if the cost was the main barrier to undergo cataract surgery in Paraguay. METHODS: We conducted a cohort study with patients screened in the 2011 Rapid Assessment of Avoidable Blindness (RAAB) who had reported that the cost was the main barrier to undergo cataract surgery in Paraguay. All patients with operable cataract from the RAAB study and with registered telephone numbers were interviewed by telephone and were offered free surgery services. The patients who did not come for surgery were re-interviewed by telephone to analyze the reasons for not undergoing the operation. RESULTS: Out of 122 patients identified in the RAAB study with barriers for cataract surgery, 69 (56.6%) reported that the surgical fee was the main barrier; 52 (75.4%) of them had their telephone numbers registered. Thirty-six (69.2%) patients did not reside in the metropolitan area of Asunción. Six patients (12%), all from Asunción, agreed to undergo free surgery. Forty-six patients did not agree the free surgery mainly due to the costs associated with their transportation (n=31, 67%) and the travel costs of their companion (n=6, 13%). CONCLUSION: Surgery fee alone was not the major contributing factor for not undergoing cataract surgery. Place of residence and other indirect out-of-pocket expenses, such as transportation and companion-related costs appear to be more relevant. While further investigation is needed to assess if reducing the cost of transport will improve the uptake, the findings in this study suggest that a surgical package with all costs should be offered to patients of cataract surgical programs to increase cataract surgical coverage in Paraguay.

Objetivo: Determinar se a taxa de cirurgia é a principal barreira para a adesão à cirurgia de catarata no Paraguai. Métodos: Foi realizado um estudo de coorte com pacientes identificados na Avaliação Rápida da Cegueira Evitável (RAAB) de 2011, que haviam informado ser a taxa para a cirurgia a principal barreira para se submeter à cirurgia de catarata no Paraguai. Todos os pacientes com catarata operável a partir do estudo RAAB, cujos números de telefone foram registrados, foram entrevistados por telefone e foi oferecida a cirurgia gratuitamente. Aqueles pacientes que não compareceram para a cirurgia foram então re-entrevistados por telefone para confirmar as suas razões para não fazer a cirurgia. Resultados: Das 122 pessoas identificadas no estudo RAAB com barreiras para a cirurgia de catarata, 69 (56,6%) relataram a taxa cirúrgica como a principal barreira para a cirurgia; 52 (75,4%) destes indivíduos tiveram seus números de telefone registrados. Trinta e seis (69,2%) pacientes não residiam na área metropolitana de Assunção. Seis pacientes (12%) aceitaram se submeter à cirurgia gratuita, todos eles de Assunção. Dos 46 pacientes que não aceitaram a cirurgia gratuita, as duas principais razões para o não comparecimento foi o custo de transporte (n=31, 67%) e os custos de viagem de seu companheiro (n=6, 13%). Conclusão: A taxa de cirurgia de catarata per se não foi a barreira principal. Local de residência e outras despesas pessoais indiretas, como transporte e custos relacionados à companhia parecem ser mais relevantes. Embora mais estudos sejam necessários para avaliar se a redução do custo do transporte vai melhorar a adesão, os resultados sugerem que um pacote cirúrgico que inclua todos os custos deve ser oferecido aos pacientes dos programas de ...

RESUMO

PURPOSE: To report the prevalence and causes of blindness in people aged 50 years and older in Paraguay, and to compare these with the previous national survey in 1999, focusing on planning of future eye care activities. METHODS: A rapid assessment of avoidable blindness (RAAB) was conducted in 2011. A total of 60 clusters of 50 residents aged 50 years and older were randomly selected and visited, and 2862 people were examined (95.4%). Survey data were analyzed with the RAAB software and compared with findings of a similar survey from 1999. RESULTS: The prevalence of bilateral blindness in Paraguay was 1.0% (95% confidence interval, CI, 0.6-1.6) in 2011, significantly less than the 3.1% (95% CI 2.2-4.4) in 1999. Prevalence of bilateral cataract and cataract eyes had also reduced significantly for visual acuity, VA, <3/60, VA < 6/60 and VA < 6/18. Cataract surgical coverage in persons doubled to 90% for VA < 3/60, 78% for VA < 6/60 and 63% for VA < 6/18. Visual outcome after cataract surgery also improved to nearly the World Health Organization norm. Cataract was the main cause of blindness (43.8%), followed by severe visual impairment (40.5%). Uncorrected refractive errors were the main cause of moderate (78.0%) and the second cause of severe (18.9%) visual impairment. CONCLUSION: The reduction in blindness and visual impairment due to cataract in Paraguay between 1999 and 2011 was highly significant. Results and coverage of cataract surgical services improved substantially. The reported numbers of cataract operations may not have been complete as these do not seem to match the dramatic improvement in the cataract situation in Paraguay.

RESUMO

PURPOSE: To collect cataract surgery rates data in 19 Latin American countries over a 4-year period as data published to date have been limited. METHODS: Cataract surgery rates were obtained from National Society of Ophthalmology, National VISION 2020/Prevention of Blindness Committee and Ministry of Health representatives for each country for 2005 to 2008. Economic (gross national income per capita) and other data were collected from publicly available databases. Linear and power correlations between gross national incomes and cataract surgery rates were calculated. RESULTS: Over the study period, most countries increased their cataract surgery rates, with the largest increases observed for Venezuela (186%), Nicaragua (183%), Costa Rica (100%), Uruguay (97%), and Peru (88%). Mean cataract surgery rates for 2005, 2006, 2007, and 2008 for the ensemble of countries were 1545, 1684, 1660, and 1822 per million population, respectively, with a growth over the study period of 17.9%, concurrent with an increase of 57 million (11.5%) in the population. A good correlation between cataract surgery rate and gross national income per capita was found (P < .001). CONCLUSIONS: Although progress is being made in the region, the cataract surgery rates represent only one parameter. When they are examined in the context of cataract surgical coverage it is clear that substantial proportions of bilaterally blind persons are still not receiving surgery.

RESUMO

PURPOSE: To estimate the burden of visual loss and blindness due to cataract in people aged 50 years and over in Paraguay. METHODS: Forty clusters of 60 persons each who were 50 years and older (2400 eligible persons) were selected by systematic random sampling from the entire population of Paraguay. A total of 2136 persons were examined (89% coverage). RESULTS: For the population 50 years and over, the age- and gender-adjusted prevalence of bilateral blindness (VA < 3/60 with available correction) was 3.14% (95% CI: 2.2-4.4). The adjusted prevalence of bilateral cataract blindness (VA < 3/60) was 2.01% (95% CI: 1.3-3.0), making cataract the major cause of bilateral blindness in this age group (64%). The adjusted prevalence of bilateral severe visual impairment (VA < 6/60 with available correction) was 5.17% (95% CI: 3.9-6.7) and the adjusted prevalence of severe visual impairment due to bilateral cataract (VA < 6/60) was 3.09% (95% CI: 2.2-4.3). The cataract surgical coverage (persons) was 44% for bilaterally blind persons with VA < 3/60; 36% for persons with bilateral VA < 6/60; and 28% for any eye with VA < 6/60 due to cataract. With IOL implantation, 77% of the operated eyes could see 6/18, against 46% of the non-IOLs (p < 0.005), a significant better outcome. CONCLUSION: There is a need to increase the cataract surgical coverage in Paraguay. The number of eye surgeons is adequate but the accessibility of cataract surgical services in rural areas and the affordability of surgery to large sections of society are major constraints.
