Machine learning algorithms facilitate automatic early diagnosis, with methods such as deep neural network and geometric feature fusion producing high accuracy in predicting cerebral palsy from short videos. It is a developmental disability.Once a person is diagnosed with cerebral palsy, further diagnostic tests are optional. Neuroimaging with CT or MRI is warranted when the cause of a persons cerebral palsy has not been established. An MRI is preferred over CT, due to diagnostic yield and safety. When abnormal, the neuroimaging study can suggest the timing of the initial damage. The CT or MRI is also capable of revealing treatable conditions, such as hydrocephalus, porencephaly, arteriovenous malformation, subdural hematomas and hygromas, and a vermian tumour (which a few studies suggest are present 5–22% of the time). Furthermore, an abnormal neuroimaging study indicates a high likelihood of associated conditions, such as epilepsy and intellectual disability. There is a small risk associated with sedating children to facilitate a clear MRI.The age when CP is diagnosed is important, but medical professionals disagree over the best age to make the diagnosis. The earlier CP is diagnosed correctly, the better the opportunities are to provide the child with physical and educational help, but there might be a greater chance of confusing CP with another problem, especially if the child is 18 months of age or younger. Infants may have temporary problems with muscle tone or control that can be confused with CP, which is permanent.
Berlins edema (commotio retinae) a common condition caused by blunt injury to the eye. It is characterized by decreased vision in the injured eye a few hours after the injury. Under examination the retina appears opaque and white in colour in the periphery but the blood vessels are normally seen along with "cherry red spot" in the foveal region. This whitening is indicative of cell damage, which occurs in the retinal pigment epithelium and outer segment layer of photoreceptors. Damage to the outer segment often results in photoreceptor death through uncertain mechanisms. Usually there is no leakage of fluid and therefore it is not considered a true edema. The choroidal fluorescence in fluorescent angiography is absent. Visual acuity ranges from 20/20 to 20/400. The prognosis is excellent except in case of complications of choroidal rupture, hemorrhage or pigment epithelial damage, but damage to the macula will result in poorer recovery. The outcome can be worsened in the case of retinal detachment, atrophy or hyperplasia. Visual field defects can occur. In late cases cystoid macular edema sometimes develops which can further lead to macular destruction. Commotio retinae is usually self limiting and there is no treatment as such. It usually resolves in 3–4 weeks without any complications and sequelae. == References ==
