Glaucoma can cause eye redness. This phenomenon is particularly evident during acute angle-closure glaucoma attacks, when blood flow increases significantly. It's important to regularly visit the hospital to monitor intraocular pressure and ensure early detection, diagnosis, and treatment. It is recommended to protect your eyes and get adequate rest in daily life. If obvious optic nerve atrophy occurs, medications that nourish the nerves should be used as soon as possible.
