In clinical practice, conjunctivitis does not normally cause dizziness and nausea in patients with conjunctivitis. Conjunctivitis is the most common clinical eye disease in ophthalmology. When a patient has conjunctivitis, the main symptom is a foreign body sensation in the eye, as if something has entered the eye, and some patients also experience tearing, itching, and even a large amount of discharge from the eye. When a patient has conjunctivitis, the condition can be completely cured with topical medication. However, if a patient has conjunctivitis and becomes dizzy and nauseous, it is important to undergo further investigation, as simple conjunctivitis will not cause dizziness and nausea. It is recommended that patients undergo a comprehensive examination to identify the cause of their dizziness and nausea, and then take symptomatic treatment.
