Cerebral hemorrhage patient coma hear call tears is generally not a conscious performance, cerebral hemorrhage patient coma tears may be bulbar conjunctival edema, reflex tear secretion, eyelids are not closed and other reasons. 1.conjunctival edema: the cerebral hemorrhage patient’s coma and tears may be due to the amount of cerebral hemorrhage, compression of the surrounding brain tissue to form cerebral edema. This leads to increased intracranial pressure, which can be manifested as bulbar conjunctival edema, which can be clinically manifested as a pseudo-sign of tearing. 2. Reflex tear secretion: due to the increased intracranial pressure in patients with cerebral hemorrhage, it may lead to the dilation of blood vessels around the eyes, which will make the muscles around the eyes contract and stimulate the lacrimal gland. This may cause reflex tear secretion, resulting in involuntary tearing of the patient’s eyes. 3. Eyelids not closed: patients in coma with cerebral hemorrhage are unable to close their eyelids because of the loss of consciousness, which leads to the lack of muscle tone of the orbicularis oculi muscle. The cornea is exposed to the air for a long time, which will easily cause the phenomenon of tearing. Cerebral hemorrhage coma patients should be timely under the guidance of the doctor to carry out relevant examinations and treatments, family members should do a good job of patient care.
