On the Glasgow coma scale, what score indicates no response to eye stimulation?

A score of 1 on the Glasgow Coma Scale (GCS) signifies that there is no eye opening response to any form of stimulation, whether it is spontaneous, to verbal command, or to painful stimuli. The GCS is designed to assess a patient's level of consciousness based on three criteria: eye opening, verbal response, and motor response. In the eye opening component, a score of 1 indicates a complete lack of response, which is critical for evaluating the severity of a patient's condition, especially in trauma or neurological assessments. This lack of eye response is often associated with severe brain injury or coma, highlighting the importance of this score in clinical diagnosis and management. Higher scores in the eye opening component reflect increasing levels of responsiveness, which is not applicable when the score is 1.
