Violent coughing usually causes patients to develop ocular congestion, mainly referring to conjunctival congestion. After coughing violently, the patient will cause an increase in abdominal pressure, which will stimulate the capillaries in the eyeballs, resulting in dilatation or rupture of the patient’s conjunctival capillaries, leading to conjunctival congestion or subconjunctival hemorrhage, which is manifested as a reddening of the eyes. In addition to coughing can cause patients with conjunctival congestion, inflammation, trauma, etc. can also lead to patients with conjunctival congestion, such as conjunctivitis, keratitis. Eye trauma patients in the early stage of the injury can be localized cold compresses on the eyes, 48 hours later, warm towels can be used to apply hot compresses on the eyes, to promote the relief of eye discomfort. Conjunctivitis patients can follow the doctor’s instructions to use tobramycin eye drops and other drugs to control inflammation and promote recovery. It is recommended that patients with obvious eye redness consult a hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
