Introduction
Sudden eye redness may be caused by physiological factors or conditions such as keratitis. When conjunctivitis is severe, it may lead to rupture of cells in the conjunctiva, causing sudden redness of the white part of the eye. Treatment under a doctor's guidance may include erythromycin eye ointment, penicillin V potassium tablets, or chloramphenicol eye drops. Additionally, glaucoma can also cause conjunctival hemorrhage and should be treated promptly according to medical advice.
Sudden eye redness may be caused by physiological factors or pathological conditions such as keratitis or conjunctivitis. It is important to seek timely medical attention and receive targeted treatment. Specific details are as follows:
1. Physiological Causes
If one frequently stays up late using a mobile phone or working, leading to excessive eye fatigue, eye redness may occur. However, this condition is generally mild. Symptoms usually improve with adequate rest and by avoiding prolonged熬夜 (staying up late).
2. Pathological Causes
1) Keratitis
When the cornea becomes inflamed due to infection by tuberculosis bacteria, persistent inflammation may stimulate the eye and cause sudden redness. It is recommended to follow a doctor's instructions to use anti-infective medications such as tobramycin eye drops, ofloxacin eye drops, or natamycin eye drops.
2) Conjunctivitis
When inflammation of the conjunctiva caused by viral or bacterial infection becomes severe, it may lead to rupture of cells in the conjunctiva, resulting in sudden redness of the white part of the eye. Symptoms can be improved under medical guidance using medications such as erythromycin eye ointment, penicillin V potassium tablets, or chloramphenicol eye drops.
In addition, glaucoma may also cause conjunctival hemorrhage. Timely treatment according to medical advice is essential to prevent worsening symptoms.
