Nutrition
Nutritional support is necessary in all patients with acute brain injury. Enteral feeding, or through mouth via tube, is the preferred method, unless contraindicated. Additional attention must be placed on the solute concentration of the formulations to avoid free water intake, decreased serum osmolality, and worsening of the cerebral edema.Elevated blood glucose, or hyperglycemia, is associated with increased edema in patients with cerebral ischemia and increases the risk of a hemorrhagic transformation of ischemic stroke. Maintaining a normal blood glucose level of less than 180 mg/dL is suggested. However, tight glycemic control of blood glucose under 126 mg/dL is associated with worsening of stroke size. Specific measures
Although cerebral edema is closely related to increased intracranial pressure (ICP) and cerebral herniation and the general treatment strategies above are useful, the treatment should ultimately be tailored to the primary cause of the symptoms. The management of individual diseases are discussed separately. The following interventions are more specific treatments for managing cerebral edema and increased ICP:

Osmotic therapy
The goal of osmotic therapy is to create a higher concentration of ions within the vasculature at the blood–brain barrier. This will create an osmotic pressure gradient and will cause the flow of water out of the brain and into the vasculature for drainage elsewhere. An ideal osmotic agent produces a favorable osmotic pressure gradient, is nontoxic, and is not filtered out by the blood–brain barrier.
Cornea verticillata, also called  vortex keratopathy or whorl keratopathy, is a condition characterised by corneal deposits at the level of the basal epithelium forming a faint golden-brown whorl pattern. It is seen in Fabry disease or in case of prolonged amiodarone intake. Presentation
No ocular complaints or visual difficulty is usually present. Pathophysiology
This keratopathy is probably a type of drug-induced lipidosis. Diagnosis
