Navigating diagnostic and therapeutic challenges in ocular manifestations of Hansen's disease and trachoma: A narrative review.

Neglected tropical diseases (NTDs) encompass a group of approximately 20 diseases prevalent in tropical and subtropical regions, closely associated with poverty, affecting over a billion people in low-income countries. This manuscript aims to explore the ocular manifestations and burden of two significant NTDs, namely Hansen's disease and trachoma while addressing gaps in understanding and management. Hansen's disease, caused by Mycobacterium leprae , has a long history and presents with diverse neurological and ocular manifestations. Despite the availability of treatment, ocular complications persist, leading to significant visual impairment in some cases. The manuscript emphasizes the importance of early diagnosis, regular ophthalmic examinations, and follow-ups to prevent and control ocular complications, reducing the burden of visual impairment and blindness. Trachoma, caused by Chlamydia trachomatis , remains the leading infectious cause of blindness in underdeveloped and remote areas. The manuscript highlights the clinical diagnosis and implementation of the World Health Organization's (WHO's) SAFE (surgery, antibiotics, facial hygiene, and environmental sanitation) strategy to prevent transmission and associated blindness. However, challenges in health surveillance tools and underreporting of trachoma cases are addressed, emphasizing the need for improved strategies to combat the disease effectively. Through a comprehensive review of the ocular manifestations and management of Hansen's disease and trachoma, this manuscript contributes to the existing knowledge base and enhances a deeper understanding of these NTDs. Addressing gaps in understanding and management emphasizes the importance of implementing WHO's strategies and collaborative efforts to achieve the global goal of reducing the burden of NTDs and improving community health and well-being. The manuscript underscores the significance of early intervention, preventive measures, and technological advancements, providing valuable insights for policymakers, healthcare professionals, and researchers working in the field of NTDs.

Prophylaxis and treatment of diseases in western São Paulo state: the Sanitation Service and trachoma in the early twentieth century. / A profilaxia e o tratamento das enfermidades do oeste paulista: o Serviço Sanitário e o tracoma no princípio do século XX.

In 1906, Emílio Ribas reorganized the Sanitation Service and centralized São Paulo state public health services in the state capital. A campaign to combat trachoma, an ophthalmic disease, was implemented as part of this project. This article analyzes this campaign, which provided care for the sick living on rural properties in a process that predated the 1917 Rural Sanitary Code. The empirical data was obtained from government reports, decrees, medical journals and newspapers. We conclude that Ribas, by creating an organization that integrated the efforts of the sanitary districts and the Trachoma Commission medical teams, sought to form a complex apparatus to combat the diseases present in both urban areas and the countryside.

Em 1906, Emílio Ribas reorganizou o Serviço Sanitário e centralizou na capital os serviços de saúde pública do estado de São Paulo. Nesse projeto, a campanha de combate ao tracoma, uma enfermidade oftálmica, foi implantada. Este artigo analisa essa campanha que atendeu os enfermos das propriedades rurais em um processo que antecedeu ao Código Sanitário Rural de 1917. O material empírico foi composto por relatórios governamentais, decretos, periódicos médicos e jornais. Concluímos que Ribas, ao criar uma estrutura que unificou os esforços dos distritos sanitários com as equipes de atendimento das Comissões do Tracoma, buscou formar um complexo aparato para combater as enfermidades presentes tanto nas áreas urbanas quanto na zona rural.

Leading causes of blindness worldwide.

The main causes of blindness and visual disabilities, as described in documents published by the World Health Organization (WHO), are discussed.

Corneal blindness: a global perspective.

Diseases affecting the cornea are a major cause of blindness worldwide, second only to cataract in overall importance. The epidemiology of corneal blindness is complicated and encompasses a wide variety of infectious and inflammatory eye diseses that cause corneal scarring, which ultimately leads to functional blindness. In addition, the prevalence of corneal disease varies from country to country and even from one population to another. While cataract is responsible for nearly 20 million of the 45 million blind people in the world, the next major cause is trachoma which blinds 4.9 million individuals, mainly as a result of corneal scarring and vascularization. Ocular trauma and corneal ulceration are significant causes of corneal blindness that are often underreported but may be responsible for 1.5-2.0 million new cases of monocular blindness every year. Causes of childhood blindness (about 1.5 million worldwide with 5 million visually disabled) include xerophthalmia (350,000 cases annually), ophthalmia neonatorum, and less frequently seen ocular diseases such as herpes simplex virus infections and vernal keratoconjunctivitis. Even though the control of onchocerciasis and leprosy are public health success stories, these diseases are still significant causes of blindness--affecting a quarter of a million individuals each. Traditional eye medicines have also been implicated as a major risk factor in the current epidemic of corneal ulceration in developing countries. Because of the difficulty of treating corneal blindness once it has occurred, public health prevention programmes are the most cost-effective means of decreasing the global burden of corneal blindness.

Corneal blindnesses in tropical environment.

Corneal blindnesses make up a main public health problem in numerous developing countries where they constitute a sign of low sanitary level. The main diseases which cause corneal blindnesses are: Trachoma. Xerophthalmia. Measles. Corneal ulcerations and keratitis. Onchocercosis. Neonatorum ophthalmia. Leprosy. Injuries. Some therapeutic practices. Epidemiological analysis leads to the definition of risk groups: Small children. Isolated rural communities. Unhealthy urban communities. Out of place populations. Under-fed populations. Only a joint prevention can be able to fight against this social, economic, a human plague constituted by corneal blindnesses. Simple prevention measures which are often not very expensive, showed their efficiency. They are as follows: Individual and collective hygiene measures. Improvement of alimentary conditions. Earliness and quickness in ocular care. Vaccination against measles. Improvement of the care to mother and child. Sanitary education for prevention. These prevention tasks are supported by the health workers who are spread out inside the population. Their formation, the means they are granted with constitute a main priority which has to be taken into account in the choices and the decisions to be made in order to fight against blindness linked with cornea opacification with efficacy.

Ophthalmic disease in Western Samoa.

Since the last report on eye disease in Western Samoa in 1959 by Dr. Elliott, the population has increased from 97,000 to 158,000. The country now has a full-time ophthalmologist but could benefit from a larger eye care service. The distribution of disease is very similar to that found in 1959, with pterygium, cataract and injuries comprising the most frequent eye problems. Acute angle-closure glaucoma is much more common than open-angle glaucoma and is associated with a plateau iris configuration.
