RESUMEN

PURPOSE: This study aimed to describe the behavioral patterns of data on cataract surgery performed in the Brazilian public health system before, during, and after the COVID-19 outbreak and estimate the setbacks generated by the pandemic to guide public policies. MATERIALS AND METHODS: This was an observational, longitudinal, and descriptive epidemiological study based on data retrieved from the public health system's databases of cataract surgeries performed each year and in each region from 2015 to 2022. RESULT: In Brazil, compared with the average of the 5-years preceding the pandemic, a 23 % reduction in the number of cataract surgeries was observed in 2020, followed by a 21 % increase in 2021, compensating for the majority of patients that were not operated on. However, the worsening situation of blindness caused by cataracts due to the pandemic not be avoided in the Central-West region, where unrecovered cases continue to accumulate. CONCLUSION: The COVID-19 pandemic did not worsen the situation of cataract blindness in Brazil due to the efficacy of the measures taken by the government in resuming elective surgeries. However, the auhtors recommend that the distribution of resources for cataract surgeries should consider regional discrepancies based on epidemiological data.

RESUMEN

Dermal filler injection is among facial rejuvenation treatments that have been increasingly used. Despite being a minimally invasive procedure, it can lead to severe complications such as blindness. A review of all cases of filler- -induced visual loss in the world literature was conducted to summarize the mechanisms, anatomical considerations, and clinical ophthalmologic course, current strategies of prevention and management, and trends over the years. We identified 233 cases of filler-induced visual loss, and 172 patients had a severe visual impairment in at least one eye. The typical patients are young women who received injections of hyaluronic acid or autologous fat in the glabella or nose, and the typical presentations were sudden ocular pain, ptosis, and ophthalmoplegia due to vascular occlusion. The findings of this study also suggest an increase in the number of unlicensed professionals performing the procedure. Even though the continued development of dermal fillers has improved the treatment options available, further studies and strategies are necessary to reduce the incidence and minimize the consequences of filler-induced visual loss.

RESUMEN

ABSTRACT This review is intended to describe the therapeutic approaches for corneal blindness, detailing the steps and elements involved in corneal wound healing. It also presents the limitations of the actual surgical and pharmacological strategies used to restore and maintain corneal transparency in terms of long-term survival and geographic coverage. In addition, we critically review the perspectives of anabolic agents, including vitamin A, hormones, growth factors, and novel promitotic and anti-inflammatory modulators, to assist corneal wound healing. We discuss the studies involving nanotechnology, gene therapy, and tissue reengineering as potential future strategies to work solely or in combination with corneal surgery to prevent or revert corneal blindness.(AU)


RESUMO O presente trabalho traz uma revisão das abordagens terapêuticas para a cegueira da córnea. O estudo detalha as etapas e os elementos envolvidos na cicatrização da córnea. Ele mostra as limitações das estratégias cirúrgicas e farmacológicas usadas para restaurar e manter a transparência da córnea em termos de sobrevida a longo prazo e alcance geográfico. As perspectivas dos agentes anabólicos, incluindo vitamina A, hormônios, fatores de crescimento e novos moduladores pró-mitóticos e anti-inflamatórios para auxiliar a cicatrização da ferida na córnea, são revisadas criticamente. Aqui, apresentamos estudos envolvendo nanotecnologia, terapia gênica e reengenharia de tecidos como possíveis estratégias futuras para atuar de maneira isolada ou combinada com a cirurgia da córnea para prevenir ou reverter a cegueira corneana.(AU)

RESUMEN

RESUMO Objetivo: Comparar por meio de questionários estruturados, o conhecimento sobre a doença, o manejo de colírios e a adesão ao tratamento de portadores de glaucoma pertencentes a dois públicos com nível de escolaridade e nível sócio econômico distintos. Métodos: Foi realizado um estudo transversal analítico aplicando-se questionários estruturados, com base em estudo exploratório para avaliação do nível de conhecimento dos portadores de Glaucoma em relação a doença em dois públicos diferentes: sistema único de saúde (SUS) e planos privados de saúde. Os questionários foram aplicados por médicos residentes em Oftalmologia. A amostra é composta de 202 pacientes dentre eles 100 atendidos pelo SUS e os outros 102 pacientes dos planos privados de saúde. Todos os questionários possuem termo de consentimento livre e esclarecido assinado pelo participante e pelo pesquisador responsável. Resultados: Os pacientes foram divididos em dois grupos, compostos por: 100 pacientes SUS e 102 planos de saúde privado. Os resultados revelaram que: 58,6% dos pacientes do SUS tinham escolaridade nenhuma a fundamental incompleto e 25,5% dos pacientes de convênio tinham algum nível superior); 49% do grupo SUS tinham renda com menos de 2 salários mínimos enquanto que grupo convênio apresentou 39,4% com mais de 4 salários mínimos (p<0,001); 51,5% do grupo SUS não tem gastos com compra de colírios e 67,4% do grupo convênio gasta mais de R$30,00 (p<0,001) portanto 77% do grupo SUS recebe ajuda e 52,5% do grupo convenio não recebe ajuda (p<0,001); 63,6% do grupo convenio acredita que a quantidade de instilações a mais do colírios não obtêm uma melhora do glaucoma, enquanto aproximadamente 50% do grupo SUS relata que há uma melhora com aumento das instilações ou não tem ideia (p=0,030); Ambos os grupos obtiveram um nível de conhecimento geral da doença semelhante, sem diferença estatística. Conclusão: Concluímos que, independente do nível de escolaridade e nível socioeconômico, havendo boa relação médico-paciente, além de acompanhamento orientado e próximo, é possível transmitir conhecimento adequado sobre a doença elevando o nível de adesão ao tratamento pelo paciente.


ABSTRACT Objective: Compare, through structured questionnaires, the knowledge about disease, management of eye drops and adherence to treatment of glaucoma patients disposed in two groups according to educational levels and socioeconomic levels. Methods: A cross-sectional analytical study was carried out applying structured questionnaires based on an exploratory study to assess the level of Glaucoma patients' knowledge relationated with the disease in two different audiences: the single health system (SUS) and private health plans. The questionnaires were used by doctors residents in Ophthalmology. A sample was composed of 202 patients among which 100 were attended by SUS and the others 102 patients were holders of private health plans. All questionnaires have a free and informed consent form signed by the participant and the responsible researcher. Results: Patients were divided into two groups, consisting of: 100 SUS patients and 102 private health plans. The results revealed that: 58.6% of SUS patients had incomplete elementary schooling and 25.5% of private health insurance patients had some level of higher education; 49% of the SUS group had an income with less than 2 minimum wages while the health insurance group presented 39.4% with more than 4 minimum wages (p <0.001); 51.5% of the SUS group has no spending on eye drops and 67.4% of the health insurance group spends more than R $ 30.00 (p <0.001) so, 77% of the SUS group receives financial aid and 52.5% of the health insurance group does not receive any financial support (p <0.001); 63.6% of the health insurance group believes that the bigger amount of instillations than eyedrops does not improve glaucoma, while approximately 50% of the SUS group reports that there is an improvement when increasing instillations or has no idea (p = 0.030); Both groups obtained a similar level of general knowledge of the disease, with no statistical difference. Conclusion: We conclude that regardless of educational and socioeconomic level if prevails a good doctor-patient relationship, in addition to close monitoring, it is possible to transmit adequate knowledge about the disease, increasing levels of treatment adherence.

RESUMEN

Objetivo: Describir la discapacidad visual del diabético de 50 años y más de edad y la cobertura de la atención oftalmológica en Cuba durante el año 2016. Métodos: Se realizó una investigación epidemiológica, descriptiva y transversal que tomó la encuesta rápida de ceguera evitable realizada en Cuba en el año 2016, la cual incluyó la retinopatía diabética validada por la Organización Mundial de la Salud. Con los datos obtenidos en los cuestionarios se confeccionó una base de datos donde se tomaron todos los diabéticos conocidos o no con discapacidad visual. Resultados: La prevalencia de cualquier tipo de discapacidad visual en el diabético es de 25,4 por ciento (21,8-28,9). El riesgo de desarrollar discapacidad visual moderada, grave y ceguera es de 19,4 por ciento (16,5-22,3), 2,8 por ciento (1,0-4,6) y 3,2 por ciento (1,5-4,8) respectivamente. La catarata es la primera causa de discapacidad. El riesgo de discapacidad visual en el diabético es similar para uno y otro sexo y se incrementa con la edad. Las coberturas de tratamiento son bajas. Conclusiones: En Cuba, alrededor de un cuarto de los diabéticos tienen algún riesgo de discapacidad visual. El diabético tiene mayor riesgo de discapacidad visual moderada; sin embargo, el riesgo de discapacidad visual grave y de ceguera es el mismo para toda la población de 50 años y más de edad. La catarata y la retinopatía diabética son las causas más frecuentes de discapacidad visual en el diabético. Se evidencian dificultades con la atención oftalmológica, que incluye el examen y la cobertura de tratamiento de la catarata y del láser para la retinopatía diabética(AU)


Objective: Describe visual impairment among diabetics aged 50 years and over, and the coverage of ophthalmological care in Cuba in the year 2016. Methods: A descriptive cross-sectional epidemiological study was conducted based on the Rapid Assessment of Avoidable Blindness survey developed in Cuba in the year 2016, which included diabetic retinopathy with validation by the World Health Organization. The data obtained from the questionnaires were transferred to a database of visually impaired known and unknown diabetics. Results: Prevalence of any sort of visual impairment among diabetics is 25.4 percent (21.8-28.9). Risk of developing moderate visual impairment, severe visual impairment or blindness is 19.4 percent (16.5-22.3), 2.8 percent (1.0-4.6) and 3.2 percent (1.5-4.8), respectively. Cataract is the leading cause of impairment. Risk of visual impairment among diabetics is similar in the two sexes and increases with age. Treatment coverage is low. Conclusions: In Cuba, about one fourth of the diabetics are at some risk of visual impairment. Diabetics are at a higher risk of moderate visual impairment. However, the risk of severe visual impairment and blindness is the same as for the population aged 50 years and over. Cataract and diabetic retinopathy are the most common causes of visual impairment among diabetics. Difficulties were found in ophthalmological care, including examination and treatment coverage for cataract and laser therapy for diabetic retinopathy(AU)

RESUMEN

The burden of corneal blindness and visual deficiency can be felt worldwide. Its association with several endemic diseases such as childhood blindness, trauma, infectious keratitis (including variants caused by herpes, hanseniasis, and fungi), vitamin A deficiency, diabetes mellitus, and other dry eye syndromes reflects its poorly understood underlying mechanisms and suggests that the actual frequency of the disease is underestimated. The low effectiveness of preventive and therapeutic strategies against corneal scarring or deformity predicts a high frequency of patients with corneal blindness in the future. Corneal blindness is associated with environmental factors and socioeconomic limitations that restrain health assistance and maintain a modest efficiency of the current therapeutic strategies for resolving corneal diseases in large-scale programs. We present here a critical review of the concepts associated with corneal blindness that need to be considered when planning strategies to prevent and treat corneal blindness worldwide (to be able to leave Plato's cave, where corneal blindness is encaged.

RESUMO O problema da deficiência visual e da cegueira corneal abrange o mundo todo e corresponde à quarta causa de cegueira e deficiência visual, com acometimento estimado de mais de 16 milhões de pessoas. A associação com várias doenças endêmicas, como cegueira infantil, trauma, ceratites infecciosas (incluindo herpes, hanseníase e fungos), hipovitaminose A, diabetes mellitus e outras causas de síndromes de olho seco, indicam que a verdadeira frequência é subestimada e que os diferentes mecanismos são pouco conhecidos. A baixa eficácia na prevenção e tratamento da cicatriz e deformidade da córnea permite antecipar que a prevalência da cegueira corneal irá crescer no futuro. As razões para o aumento da cegueira corneal envolvem fatores ambientais, limitações socioeconômicas para ampliar a assistência à saúde e a modesta eficiência das estratégias terapêuticas para resolver o problema em grande escala. O presente trabalho traz uma revisão crítica dos conceitos associados à cegueira corneal. Essa análise é uma etapa necessária para preparar o caminho com o objetivo de deixar a caverna que encarcera a cegueira corneal, em analogia ao mito de Platão, e melhorar as estratégias para prevenir e tratar a cegueira corneal em escala mundial.

RESUMEN

OBJECTIVE: To assess the feasibility of a novel surgical technique in painful blind eyes. DESIGN: A prospective safety study conducted at the Federal University of Minas Gerais, Brazil. PARTICIPANTS/SAMPLES: A total of 15 end-stage glaucomatous eyes without light perception vision. METHODS: After implantation, conjunctival hyperemia, discharge, erosion, aqueous humor leakage, corneal edema, hyphema, anterior chamber cells and depth, dislocation of the implant, and filtering bleb height were assessed by slit-lamp biomicroscopy. Intraocular pressure was measured preoperatively and 24 months following surgery. A numerical rating scale was used to evaluate pain. Anterior segment optical coherence tomography was also assessed. RESULTS: Laminar drainage implant surgery was performed in all patients without major complications. Mean intraocular pressure was significantly reduced after surgery without hypotensive medication (preoperatively 54.5 ± 5.1 mmHg vs 24 months after surgery 37.0 ± 15.4 mmHg, p = 0.003). Subjective ocular pain intensity also reduced (preoperatively 10 vs at 24-month follow-up visits 0). Corneal edema incidence reduced from 85.7% (95% confidence interval: 57.2%-98.2%) to 16.7% (95% confidence interval: 2.1%-48.4%) at the 24-month follow-up. No patients experienced a prolonged flat anterior chamber or erosion of overlying tissues. CONCLUSION: The surgery was feasible and safe in painful blind eyes.

RESUMEN

OBJECTIVE: To describe the implementation of a diabetic retinopathy referral network incorporating all levels of health care in La Libertad region, Peru. METHOD: The nongovernmental organization Orbis International and the Regional Institute of Ophthalmology established a network of primary, secondary and tertiary health-care facilities for diabetic retinopathy screening and treatment. The programme included the provision of three non-mydriatic retinal cameras for patient examination, the development of a flowchart to guide patient referrals, training of health personnel, investment in laser technology for treatment and the delivery of public awareness activities for blindness prevention and the need for timely screening. FINDINGS: From 2014-2017, 11 849 patients with diabetes were screened within the diabetic retinopathy referral network. In primary-care centres, 6012 patients with diabetes mellitus were identified and 5632 patients were referred for diabetic retinopathy screening. A further 4036 patients directly attended two secondary-level hospitals and 2181 attended the tertiary-level hospital for screening. This represented a 138.1% increase in diabetic retinopathy screenings from a baseline of 4977 patients screened at the regional institute of ophthalmology over 2010-2013. A total of 2922 patients (24.7%) were found to have diabetic retinopathy and 923 (31.6%) were treated: 508 with laser photocoagulation, 345 with intravitreal bevacizumab and 70 with vitreoretinal surgery. CONCLUSION: Effective and timely treatment for diabetic retinopathy is possible when patient education, screening and care are fully integrated into the general health-care system across primary-, secondary- and tertiary-level facilities. This requires the integration of professionals at all levels and all relevant specialties.

RESUMEN

Injectable fillers have become one of the most performed aesthetical treatments worldwide over the past two decades. They are frequently applied to the face, offering effective and safe alternatives to more invasive surgical procedures. Nevertheless, there are serious risks associated with filler-based treatment. Visual impairment stands as a rare yet catastrophic adverse event associated with intravascular embolization of injected material to the retina or other areas of the central nervous system; potentially leading to permanent visual loss. This article presents a comprehensive revision of blindness secondary to aesthetical filler injections, offering up-to-date strategies for prevention and management.

RESUMEN

PURPOSE: To estimate the prevalence of blindness, visual impairment, diabetes mellitus, and diabetic retinopathy in patients aged 50 years and older in the State of Nuevo León, Mexico. METHODS: Ninety-one clusters of 60 people aged 50+ were selected randomly and a rapid assessment of avoidable blindness (RAAB) was conducted. Participants had their visual acuity and cause of visual impairment assessed, underwent a random glucose test and fundoscopy under mydriasis if they had diabetes. The diabetic retinopathy (DR) degree was classified according to the Scottish diabetic retinopathy grading scheme. RESULTS: From the sample 5,055 (92.6%) people were examined. The blindness prevalence was 1.7% (95% Confidence Interval: 1.3-2.1%). Cataract (32.6%), DR (29.1%) and glaucoma (16.3%) were the leading causes of blindness. The prevalence of severe, moderate, and early visual impairment was 1.0%, 5.1%, and 7.7%, respectively. Among respondents, 31% had diabetes and 8.1% of them was not diagnosed prior to the study. Of all participants with diabetes, 50% had glucose levels of 200 mg/dl or higher and 15.7% had sight-threatening diabetic retinopathy. CONCLUSIONS: Besides strengthening of cataract intervention activities, more ophthalmic services for diabetic retinopathy and glaucoma control are needed in Nuevo León to provide timely intervention to prevent blindness.

RESUMEN

Resumo Introdução: O glaucoma e a principal causa de cegueira irreversivel no Brasil. Ate o momento nao se dispoe de uma droga ideal para o controle da pressao intraocular (PIO), geralmente necessitando associar dois ou mais medicamentos hipotensores, com frequentes instilacoes diarias e ma aderencia ao tratamento. Objetivos: Descrever quantitativa e qualitativamente as drogas usadas para controle da PIO e a eficacia do tratamento na prevencao da cegueira. Métodos: Estudo transversal retrospectivo, atraves de revisao de 420 prontuarios de portadores de Glaucoma severo acompanhados no ambulatorio do Hospital Emilio Carlos, de Catanduva-SP, de janeiro/2014 a dezembro/2016. As variaveis analisadas foram: idade, acuidade visual e medicamentos antiglaucomatosos utilizados: topicos (colirios) e sistemicos. Resultados: A media de idade dos participantes foi 62,99±16,29 anos. Foram detectados 68 casos de cegueira, sendo que 3 pacientes (0,7%)perderam a visao no tempo investigado, com referencias a periodos sem tratamento/subdose/instilacao indevida/uso de 3 ou 4 colirios. Em 73,3% dos casos conseguiu-se estabilizacao da PIO com o uso de um (38,1%) ou no maximo 02 (35,2%) colirios associados. Houve correlacao significativa entre o no de combinacoes de hipotensores topicos e o no de pacientes em uso de Acetazolamida. O medicamentomais usado foi o Maleato de Timolol (67,1%). Conclusões: Na maioria dos pacientes a PIO foi controlada com 1 ou 2 colirios associados; pequena porcentagem dos casos evoluiu para cegueira; muito provavelmente a evolucao para perda de visao foi decorrente da complexidade e ma aderencia ao tratamento.


ABSTRACT Introduction: Glaucoma is the main cause of irreversible blindness in Brazil. To date, there is no ideal drug for the control of intraocular pressure (IOP), usually requiring the combination of two or more hypotensive drugs, with frequent daily instillations and poor adherence to treatment. Objectives: To describe quantitatively and qualitatively the drugs used to control IOP and the efficacy of treatment in the prevention of blindness. Methods: A retrospective cross-sectional study was carried out through a review of 420 medical records of patients with severe Glaucoma who were followed up at the Emílio Carlos Hospital outpatient clinic in Catanduva, SP, from January 2014 to December 2016. The analyzed variables were: age, visual acuity and antiglaucomatous drugs used: topical (eye drops) and systemic. Results:The mean age of participants was 62.99 ± 16.29 years. Sixty-eight cases of blindness were detected, and three patients (0.7%) lost vision at the time investigated, with references to periods without treatment / subdose / improper instillation / use of 3 or 4 eye drops. In 73.3% of the cases, IOP stabilization was achieved with one (38.1%) or at most 02 (35.2%) associated drops. There was a significant correlation between the number of combinations of topical hypotensive agents and the number of patients taking acetazolamide. The drugmostused was Timolol (67.1%). Conclusions: In the majority of patients IOP was controlled with 1 or 2 associated eye drops; small percentage of cases evolved into blindness; most likely the evolution to loss of vision was due to the complexity and poor adherence to the treatment.

RESUMEN

Retinopathy of prematurity (ROP) is a largely avoidable cause of blindness in children worldwide, requiring high-quality neonatal care, early detection and treatment. In middle-income countries throughout Latin America, Eastern Europe and South Asia, there has been a rise in ROP blindness due to a combination of increased survival of preterm infants, resource-scarce medical environments and lack of policies, training and human resources. However, Argentina is an example of country where rates of ROP blindness have declined and ROP programmes have been successfully and effectively embedded within the health and legal system. The purpose of this study is to describe the activities and stakeholders, including Ministry of Health (MoH) and UNICEF, involved in the process, from recognition of an epidemic of ROP blindness to the development of national guidelines, policies and legislation for control. Using a retrospective mixed methods case study design, data on rates of severe ROP was collected from 13 neonatal intensive care units from 1999 to 2012, and on the proportion of children blind from ROP in nine blind schools in seven provinces. Legislative document review, focus group discussions and key informant interviews were conducted with neonatologists, ophthalmologists, neonatal nurses, parents, MoH officials, clinical societies, legislators and UNICEF officials in seven provinces. Results are presented combining the stages heuristic policy framework and Shiffman including: agenda setting, policy formulation, implementation and evaluation. By 2012, ROP had declined as a cause of blindness in children in schools for the blind as had rates of severe ROP needing treatment in the NICUs visited. Multiple factors played a role in reducing blindness from ROP in Argentina and successfully coordinating its control including national advocacy, leadership, legislation and international collaboration. Lessons learned in Argentina can potentially be scaled to other LMICs in Latin America and beyond with further context-specific research.

RESUMEN

Abstract Objective: To evaluate the clinical and epidemiological profile of patients with primary open-angle glaucoma. Methods: This is a quantitative study with cross-sectional and analytical design, which sample consisted of 425 patients treated in an unit of Specialized Care in Ophthalmology, located in the northern state of Minas Gerais, from 2004 to 2015. We collected the data using formularies that addressed demographic and clinical aspects, risk factors and the presence of undercurrent diseases. We conducted an ophthalmological examination to evaluate anatomical and functional changes. We used statistical analysis, and the results are presented by mean, standard deviation and percentiles 25, 50 and 75. Results: Females predominate (56.8%), the age group of 60 years or older (44%) and mixed skin (81.7%). A minority of participants present risk factors such as high myopia (6.3%) and diabetes mellitus (17.9%). Regarding the clinical examination, there is a prevalence of increased optic nerve excavation (≥ 0.8) and low thickness of the corneas (≤ 535 microns). Conclusion: Most people develop advanced glaucoma, with increased optic nerve excavation and changed visual fields. Other common risk factors are: family history of glaucoma, decreased thickness of the cornea and hypertension. Early diagnosis and treatment can prevent vision loss. Primary care physicians should consider referring patients who have glaucoma risk factors, for an ophthalmologic examination.


Resumo Objetivo: Avaliar o perfil clínico-epidemiológico dos indivíduos com glaucoma primário de ângulo aberto. Métodos: Trata-se de estudo quantitativo com desenho transversal e analítico, mediante amostra constituída de 425 pacientes atendidos em uma Unidade de Atenção Especializada em Oftalmologia localizada no norte do estado de Minas Gerais, Brasil, cadastrados no período de 2004 a 2015. As variáveis analisadas foram: características demográficas e clínicas, fatores de risco e presença de doenças associadas. Foi realizado exame oftalmológico para avaliar alterações anatômicas e funcionais. Para as análises estatísticas foram utilizados os programas Statistical Package for the Social Sciences (SPSS), versão 19.0. Considerou-se nível de significância p<0,05 para as variáveis categóricas. As variáveis descritivas foram apresentadas pela média, desvio-padrão e percentis 25, 50 e 75. Resultados: Predominou o gênero feminino (56,8%), a faixa etária de 60 anos ou mais (44%), e a cor da pele parda (81,7%). Fatores de risco como alta miopia (6,3%) e diabetes mellitus (17,9%) foram relatados pela minoria dos participantes. Em relação ao exame clínico, houve prevalência de escavação do nervo óptico aumentada (≥ 0,8 mm2) e baixa espessura central das córneas (≤ 535 micras). Conclusão: A maioria dos indivíduos apresenta glaucoma avançado, com escavações do nervo óptico aumentadas e campos visuais alterados. Outros fatores de risco frequentes foram: história familiar positiva para glaucoma, espessura central da córnea diminuída e hipertensão arterial sistêmica. Diagnóstico e tratamento precoces podem prevenir contra a perda de visão no glaucoma. Médicos da atenção primária à saúde devem encaminhar os pacientes que tenham fatores de risco para glaucoma, para a consulta especializada e exames oftalmológicos.
