Abnormal flow within the small blood vessels [21] Shock is a common end point of many medical conditions. [ 9 ] Shock triggered by a serious allergic reaction is known as anaphylactic shock , shock triggered by severe dehydration or blood loss is known as hypovolemic shock , shock caused by sepsis is known as septic shock , etc. Shock itself is ...
Watery eyes – due to excessive tearing. [7] Red eyes – due to dilated blood vessels on the sclera. [7] Swollen eyelids – due to inflammation. [7] Crusting at the eyelid margins/base of the eyelashes/medial canthus, generally worse on waking – due to excessive bacterial buildup along the lid margins. [4] [5] [7]
