There isn't one single country with the absolute highest rate, as it varies by glaucoma type and metric, but African nations like Mali, Ethiopia, and Botswana often show the highest age-standardized rates for overall glaucoma burden (DALYs), while East Asian populations have higher rates of angle-closure glaucoma, and African Americans face significantly higher risks for open-angle glaucoma, with estimates pointing to Sub-Saharan Africa having the highest regional prevalence for OAG.
Black people have a much higher risk of developing primary open-angle glaucoma, especially people of Afro-Caribbean descent. People of African descent are 15 times more likely to have blindness from open-angle glaucoma. People of Asian and Inuit descent have a higher risk of angle-closure glaucoma.
Primary angle-closure glaucoma disproportionately affects Asians, with up to four times greater prevalence of normal-tension glaucoma reported compared with high-tension glaucoma.
After cataracts, glaucoma is the leading cause of blindness among African Americans, who are six to eight times more likely to get the disease than white people. African Americans also tend to get glaucoma about 10 years sooner than other ethnic groups.
Nicotinamide/Niacinamide (Vitamin B3)
Nicotinamide (also known as niacinamide) has recently shown significant potential as a novel treatment for glaucoma. It was postulated as a neuroprotective agent for glaucoma in 2017 by Williams and colleagues.
Causes of Glaucoma
1. Greece. With the joint third lowest MSVI rates, alongside Switzerland, at 0.97%, Greece is officially the least visually impaired country. Additionally, it has the joint fifth lowest percentage of blindness, at 0.10%, alongside Switzerland, Finland, Ireland, Germany, Sweden, and Spain.

Early Detection Key to Saving Sight
Despite these advances, 15 percent of those diagnosed with glaucoma still went blind. Researchers emphasized the importance of getting regular eye exams to detect glaucoma in the early stages so that your ophthalmologist can prescribe vision-preserving treatment as soon as possible.
Glaucoma is six to eight times more common in African Americans than in Caucasians. Glaucoma is much more common among older people. You are six times more likely to get glaucoma if you are over 60 years old. The most common type of glaucoma, primary open-angle glaucoma, is hereditary.
While there is no cure for glaucoma, treatment can significantly slow or prevent further vision loss. Treatment options include: Medications: Prescription eye drops and oral medications can help reduce IOP by decreasing fluid production or improving drainage.
In Singapore, glaucoma affects about 3 percent of those aged over 40. This risk increases with age.
Glaucoma is the leading cause of blindness in Japan, but the Tajimi Study conducted from 2000 to 2001 showed that the prevalence of glaucoma in Japan is 5% of those over 40 years of age, and many people are unaware that they have glaucoma and do not receive appropriate medical care.
An estimated 300,000 Australians have glaucoma but about half these people don't know they have the disease. One in eight people over the age of 80 has glaucoma. The most common form of glaucoma in Australia is primary open-angle glaucoma, accounting for around 90 percent of cases.
Glaucoma And Your Overall Health. Glaucoma can ruin and destruct life. The average life expectancy of people with chronic open-angle glaucoma is approximately 12.8 years. The number of Glaucoma cases in 2020 worldwide was approximately 80 million and the projection for 2040 is approximately 111 million worldwide.
Drink Tea, Not Just Water
One study found that people who drank at least one cup of hot tea daily had a 74% lower risk of developing glaucoma. While the exact reason isn't fully understood, researchers think antioxidants in tea may protect the optic nerve by improving blood flow and reducing oxidative stress.
Screen time is not considered a direct cause of glaucoma progression, but research shows that prolonged device use can temporarily increase intraocular pressure, particularly in people who already have glaucoma. These pressure increases are usually temporary and return to baseline after you stop using screens.
Here is our list of the 20 countries with the worst vision problems.
In developed cities and countries in Asia – including Shanghai, Taiwan and Singapore – roughly 80 to 90 percent of people are nearsighted. The Asian countryside is no safe haven from myopia, either: while rates of nearsightedness are lower, only 1 in 6 rural Chinese children have the eyeglasses they need.
As a group, the Aborigines have significantly better visual acuity than the Europeans. This was true for both monocular and binocular vision. Some Aborigines have acuities below the previous postulated threshold levels.
Gradual loss of peripheral vision, often in both eyes: This is typically the earliest sign of glaucoma. You might notice that you can't see objects out of the corner of your eye as well as you used to. Over time, this peripheral vision loss can worsen, leading to tunnel vision.
