If there is red blood in the white eye with pain in the eye, it may be seen as uveitis or glaucoma. In the case of uveitis, there is usually a large amount of conjunctival congestion and pain when the eye is pressed. Symptoms usually manifest as photophobia, tearing and loss of vision, for which glucocorticoids and ciliary muscle paralyzing agents, including compound tropicamide eye drops, atropine sulfate eye drops or flumeuron eye drops, can be chosen. In the case of glaucoma, the symptoms are usually redness and swelling of the eyes, and in severe cases, systemic reactions such as dizziness, headache, nausea, vomiting, etc. This disease is caused by elevated intraocular pressure, so it is important to actively lower the intraocular pressure for treatment to avoid pressure on the optic nerve.
