Suddenly distorted eye seeing is considered to be caused by eye diseases, such as macular lesions, retinal detachment, caused by oblique astigmatism, or may be caused by cranio-cerebral diseases, such as right middle cerebral artery thrombosis, causing cerebral local damage, cranio-cerebral tumor or vascular lesions, resulting in parietal lobe damage, migraine, schizophrenia, drug intoxication, epileptic seizures, etc. In addition, patients with mental factors and hysteria may also have this symptom. Usually, if you suddenly find that your eyes are deformed, consider going to the ophthalmology clinic to rule out eye diseases first, which usually requires routine examination, fundus and macular OCT examination to rule out retinal diseases and macular diseases. If there is no obvious abnormality in the eye, consider a neurology consultation and further examination such as cranial CT or MRI.
