When an unknown substance has entered the eye, diagnostic measurement of ocular surface pH and therapeutic irrigation of the eye are essential steps to minimize the risk of long term consequences. These procedures are demonstrated here and represent critical interventions in emergency eye care. When properly executed, they serve as both diagnostic and therapeutic measures. Their simplicity and effectiveness make them essential skills in emergency and primary care settings, where rapid intervention can prevent permanent ocular damage. Time to irrigation is the most critical factor in determining outcomes, with each minute of delay potentially increasing the risk of permanent visual impairment as this can lead to permanent scarring.
