I don't know much about this either. First of all, you should help him scrub his eyes with salty boiled water and cut off the hair around his eyes, so that disinfection will be more thorough. After cleaning, apply a little erythromycin eye ointment and wrap it in gauze to see what will happen. It is best to pick the scab with a sterilized needle to see if it is suppurative, squeeze out blood, and then apply eye ointment. Don't take other drugs yet, because other anti-inflammatory drugs may irritate the eyes and aggravate the condition, so erythromycin eye ointment is more suitable. Wash your hands afterwards. Personal point of view. Good luck.
