Improper use of medication can harm the liver and even the eyes. In recent years, drug-induced cataracts, optic neuritis, retinitis, and other conditions have occurred from time to time due to improper medication. Pharmacists from the Shanghai Association of Practicing Pharmacists remind patients to pay attention when using the following medications. Antibiotic penicillin can cause allergic conjunctivitis, causing conjunctival congestion, edema, itching, and foreign body sensation. In severe cases, white secretions may appear; Streptomycin can cause retrobulbar optic neuritis, retinitis, and optic nerve atrophy; Sulfonamide can cause myopia and blurred vision. People who take excessive amounts of aspirin as antipyretic and analgesic drugs may experience allergic conjunctivitis, increased intraocular pressure, cataracts, conjunctival congestion, ulceration, corneal bullous formation, ulceration, and optic neuritis. For patients with heart disease treated with antiarrhythmic drugs such as amiodarone, continuous use for 1 to 3 months may result in corneal granular deposition and visual halo; Long term use of propranolol can cause vision loss. The anti tuberculosis drug isoniazid can cause progressive optic nerve atrophy and sudden optic neuritis in the treatment of pulmonary tuberculosis. The use of ethambutol can lead to retinal hemorrhage and green disorders. If used in combination with rifampicin, the symptoms are more prominent. If visual impairment or other symptoms of eye diseases are detected, immediate diagnosis and treatment should be sought, and medication types or doses should be adjusted according to the doctor's instructions.
