Some eye diseases can be detected by MRI and some cannot. Different tests usually have their own focus and there is no single test that can detect all diseases. MRI can play an important role in the diagnosis of many diseases in ophthalmology, such as choroidal melanoma and optic neuritis, which may need to be diagnosed using MRI. There are many diseases in ophthalmology that need to be diagnosed by other tests that cannot be detected by MRI instead, such as glaucoma, conjunctivitis, keratitis, and other diseases that cannot be detected by MRI. When patients suspect eye diseases, they need to go to the ophthalmology department of the hospital, and the doctor will determine the appropriate examination plan according to their conditions.
