How many ophthalmologists are there in the world?

A new data from 2015 (ICO and co.). Actually, there are 232,866 ophthodocs, which makes it 31,7 ophthalmologists per 1,000,000 of world population. Not bad, until we dig into the details.

Take Zambia or Zimbabwe: ~ 30 ophthalmologists per 16,000,000 of population of each country. ~1,9 ophthalmologist per million!

Russia: 13,700 ophthalmologists (95,5 ophthalmologists per 1,000,000).

Germany: 7,300 ophthalmologists (90,5 per million).

USA: 17,600 (54,7 per million).

UK: 3000 (46,4 per million).

Australia: 961 (40,1 per million).

Belarus: 600 (63,2)

Ukraine: 2973 (66,3).

A great job done by the ICO and S. Resnikoff:

Estimated number of ophthalmologists worldwide (International Council of Ophthalmology update): will we meet the needs?

To estimate 2015 global ophthalmologist data and analyse their relationship to income groups, prevalence rates of blindness and visual impairment and gross domestic product (GDP) per capita.

Online surveys were emailed to presidents/chairpersons of national societies of ophthalmology and Ministry of Health representatives from all 194 countries to capture the number and density (per million population) of ophthalmologists, the number/density performing cataract surgery and refraction, and annual ophthalmologist population growth trends. Correlations between these data and income group, GDP per capita and prevalence rates of blindness and visual impairment were analysed.

In 2015, there were an estimated 232 866 ophthalmologists in 194 countries. Income was positively associated with ophthalmologist density (a mean 3.7 per million population in low-income countries vs a mean 76.2 in high-income countries). Most countries reported positive growth (94/156; 60.3%). There was a weak, inverse correlation between the prevalence of blindness and the ophthalmologist density. There were weak, positive correlations between the density of ophthalmologists performing cataract surgery and GDP per capita and the prevalence of blindness, as well as between GDP per capita and the density of ophthalmologists doing refractions.

Although the estimated global ophthalmologist workforce appears to be growing, the appropriate distribution of the eye care workforce and the development of comprehensive eye care delivery systems are needed to ensure that eye care needs are universally met.
