Can you tell me if i could still pursue amateur boxing after a retinal detachment surgery?

Not great idea: There is no question that boxing is a significant risk factor for retinal tears and detachments. If you had a retinal detachment in one eye, you are at higher risk to have on in the other eye compared to the population at large, even without boxing. By boxing you will increase the odds of trouble (retinal detachment). So, decide wisely...
