Iran signals quick trials and executions for protesters in defiance of US warnings

The death toll in Iran has soared as authorities have carried out a brutal crackdown, with 2,571 people killed and more than 18,100 people arrested, according to the US-based Human Rights Activists News Agency (HRNA). Already, the death toll from the two-week protest movement dwarfs any other in Iran since its 1979 revolution.

Protesters said there was a heavy security force on Wednesday as authorities prepared for a mass funeral of 300 security forces and civilians killed in demonstrations.

So, 2571 confirmed deaths, one mass funeral of 300 people in one city.

Hundreds of gunshot eye injuries found in one Iranian hospital amid brutal crackdown on protests

An ophthalmologist in Tehran has documented more than 400 eye injuries from gunshots in a single hospital, as overwhelmed medical staff struggle to cope with the toll of an increasingly violent crackdown on nationwide protests by Iranian authorities.

That's 400 gunshot eye injuries per one hospital, counted by an eye doctor. Those who got hit in other body parts likely aren't included. Assuming 5 hospitals per city, that's 2000 gunshot eye injuries per city. Assuming 180 cities and towns (likely leads to overestimation due to a large number of small towns), we would get 360 000 gunshot eye injuries per Iran. Being cautious, let's divide it by 10. A cautious estimate of 36 000 gunshot eye injuries per Iran could be warranted.
