Contemporary data for causes of vision impairment and blindness form an important basis of recommendations in public health policies. Refreshment of the Global Vision Database with recently published data sources permitted modelling of cause of vision loss data from 1990 to 2015, further disaggregat...ion by cause, and forecasts to 2020.

New research explores the stress children in World Vision programmes in the Middle East and Eastern Europe region are under due to COVID-19. In addition to their fear that they themselves or their loved ones will catch the disease, children worry about economic hardships, the loss of their education..., increased violence and social isolation. But in the midst of it all, a clear message comes through – young people are hopeful about the future, they want to make a contribution and they want their voices to be heard.

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.

Diabetes mellitus (DM) is a global epidemic with significant morbidity. Diabetic
retinopathy (DR) is the specific microvascular complication of DM and affects 1 in 3 persons with DM. DR remains a leading cause of vision loss in working adult populations. Patients with severe levels of DR are report...ed to have poorer quality of life and reduced levels of physical, emotional, and social well-being, and they utilize more health care resources.
Epidemiological studies and clinical trials have shown that optimal control of blood glucose, blood pressure, and blood lipids can reduce the risk of developing retinopathy and slow its progression. Timely treatment with laser photocoagulation, and increasingly, the appropriate use of intraocular administration of vascular endothelial growth factor (VEGF) inhibitors can prevent visual loss in vision- threatening retinopathy, particularly diabetic macular edema (DME). Since visual loss may not be present in the earlier stages of retinopathy, regular screening of persons with diabetes is essential to enable early intervention.

Glaucoma, a disease that gradually affects the optic nerve, is the second leading cause of vision loss globally, and it continues to pose a challenge to the eye health professionals.
Non-communicable diseases (NCDs) & injuries and mental health conditions constitute a serious impediment to achieving the vision of Agenda 2063 to build an integrated, prosperous, and peaceful Africa driven by its own citizens. Each year, these conditions cause millions of premature deaths and disab...led lives across Africa. These conditions also lead to annual economic loss of multiple billion US-Dollars. Their burden both in terms of disease morbidity/mortality and socio-economic impact is increasing.

The World Health Organization's fact sheet on diabetes provides an overview of the disease, highlighting its increasing prevalence, particularly in low- and middle-income countries. It outlines the main types of diabetes—Type 1, Type 2, and gestational diabetes—detailing their characteristics an...d risk factors. The document emphasizes the importance of early diagnosis and management to prevent complications such as heart disease, kidney failure, and vision loss. Preventive measures include maintaining a healthy diet, regular physical activity, and avoiding tobacco use. The fact sheet also discusses WHO's initiatives aimed at monitoring, preventing, and controlling diabetes globally.
