Glaucoma is a leading cause of irreversible blindness globally. In Malawi, glaucoma accounts for 15.8% of the blindness among people aged 50 years and above. Blindness from glaucoma is preventable with early detection and timely treatment. However, glaucoma management remains a challenge to eye care... providers due to its asymptomatic progression.
These guidelines inform eye care providers about the requirements for early detection of glaucoma, and the appropriate assessment and management of glaucoma patients. The guidelines also demonstrate the need for ophthalmologists to work with secondary-level eye care providers. With
glaucoma being a permanently blinding condition, it is vital to ensure that all eye care providers are adequately equipped with skills and resources for the early detection and management of glaucoma.

Trachoma is the leading infectious cause of blindness (2). It is characterized by repeated
conjunctival infection with particular strains of Chlamydia trachomatis. This scars the conjunctivae and,
in some cases, leads to trichiasis with or without entropion. The abrasive action of eyelashes can
d...amage the cornea. In 2018, trachoma affected the poorest residents of the poorest communities of 43

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

Trachoma is the leading infectious cause of blindness worldwide. It is caused by an obligate intracellular bacterium called Chlamydia trachomatis. The infection is transmitted by direct or indirect transfer of eye and nose discharges of infected people, particularly young children who harbour the pr...incipal reservoir of infection. These discharges can be spread by particular species of flies.

Situation of Disabilities in Indonesia : Blindness and Sight Disorder
Vitamin A deficiency is a risk factor for blindness and for mortality from measles and diarrhoea in children aged 6–59 months. We aimed to estimate trends in the prevalence of vitamin A defi ciency between 1991 and 2013 and its mortality burden in low-income and middle-income countries.
Trachoma disease
Trachoma is a sequela following infection by the bacterium Chlamydia trachomatis (C. trachomatis). The disease is preventable, but still the cause of blindness in 1.9 million people world wide.
In response to the recent publication “Is onchocerciasis elimination in Africa feasible by 2025: a perspective based on lessons learnt from the African control programmes” by Dadzie et al., it is important to clarify and highlight the positive and unequivocal research and operational contributio...ns from the American experience towards the worldwide elimination of human onchocerciasis (river blindness).

Trachoma is an eye infection affecting both eyes. It is the world’s leading cause of infectious blindness. A bacterium called Chlamydia trachomatis causes trachoma. According to the World Health Organization (WHO), trachoma has caused the visual impairment of 1.8 million people. Of those people, 4...50,000 are irreversibly blind.

Trachoma Atlas is dedicated to eliminating the world's leading infectious cause of preventable blindness
Countries, partners, and donors are committed to
the global elimination of blinding trachoma by 2020.
Achieving this public health milestone requires more
than funding; it requires health personnel with the
right mix of skills, and well supported and managed
health systems. Mass drug administra...tion (MDA)
with Zithromax®, the Pfizer, Inc. donated antibiotic,
is a key component of the SAFE strategy, endorsed
by the World Health Organization. There is growing
recognition that improving all aspects of MDA, from
planning to training, recording to reporting, and
receipt of drug to distribution (the supply chain), will
be necessary if MDA programmes are going to reduce
the community burden of Chlamydia trachomatis, and
eliminate trachoma as a cause of blindness by 2020.

Trachoma is a bacterial eye infection found in poor, isolated communities lacking basic hygiene, clean water, and adequate sanitation.
Trachoma is easily spread from person to person through eye-seeking flies, hands, and clothes. Repeated infection over time leads to scarring and inward turning o...f the eyelid, causing the eyelashes to scratch the cornea — a very painful condition called trachomatous trichiasis — which eventually causes blindness if left untreated.

Trachoma, caused by particular serovars of Chlamydia trachomatis, is the leading
infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as clothing) and eye-seeking flies (particularly Musca sorbens)....
Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”. Repeated episodes of active trachoma can scar the eyelids. In some individuals this leads to trachomatous trichiasis (TT), in which one or more eyelashes on the upper
eyelid touch the eye. TT is extremely painful. It can be corrected surgically, but, if left untreated, may lead to corneal opacification, resulting in vision impairment and blindness.

The number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014.
The global prevalence of diabetes* among adults over 18 years of age has risen from 4.7% in 1980 to 8.5% in 2014.
Diabetes prevalence has been rising more rapidly in middle- and low-income countries.
Dia...betes is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation.
In 2012, an estimated 1.5 million deaths were directly caused by diabetes and another 2.2 million deaths were attributable to high blood glucose.
Almost half of all deaths attributable to high blood glucose occur before the age of 70 years.
WHO projects that diabetes will be the 7th leading cause of death in 2030
Healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use are ways to prevent or delay the onset of type 2 diabetes.
Diabetes can be treated and its consequences avoided or delayed with diet, physical activity, medication and regular screening and treatment for complications.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

Onchocerciasis causes skin and eye disease, visual impairment and neurological problems. It is mostly found in Africa, but also in Latin America and Yemen. The common name, ‘river blindness,’ gives a good indication where the disease can be found: the vector of the parasite, a small black fly of... the Simulium species, breeds in rivers where there is turbulence in the water, such as rapids, or where the flow is disturbed by overhanging vegetation.
