Severe redness of the eyes and heavy eye droppings may be caused by conjunctivitis, keratitis, dacryocystitis, etc., which need to be treated with different measures such as medication and surgery according to different causes. 1. Conjunctivitis: Microbial infection, external stimulation and other factors can cause conjunctivitis, resulting in conjunctival congestion, increased secretion, manifested as severe redness of the eyes and excessive eye droppings. Clinical general use of levofloxacin, tobramycin and other drugs for the treatment of bacterial infectious conjunctivitis, most of the local drugs, if necessary, can be combined with systemic drugs. 2. Keratitis: Patients with keratitis often have typical symptoms of eye irritation, such as eye pain, eye redness, increased secretions. Drugs commonly used in the treatment of viral keratitis include acyclovir and ganciclovir. When patients with severe corneal damage or even perforation, surgical treatment, such as corneal transplantation, is necessary. 3. Dacryocystitis: Obstruction or narrowing of the nasolacrimal duct can lead to infection, resulting in dacryocystitis, with congestion, tearing, and increased secretion in the affected eye. Saline can be used to flush the lacrimal sac, and after the pus is flushed out, antibiotics, such as ofloxacin, can be injected. If there is a lacrimal sac abscess formation and the abscess appears to be fluctuating, the doctor will incise the abscess to drain the pus and place drainage strips to relieve the symptoms. All of the above medications should be used as prescribed by the doctor and should not be self-administered. Severe red eyes and heavy eye droppings may also be due to other causes, such as impaction, and it is recommended that the patient consult a doctor for a clear diagnosis and treatment.
