The sickle cell trait strongly protects against not only retinopathy-positive cerebral malaria but also retinopathy-negative cerebral malaria, providing evidence that malarial parasites also contribute to retinopathy-negative cerebral malaria and are not innocent bystanders.

Clinical, clinicopathological and image data from Malawian children shows that sequestration in P. falciparum cerebral malaria is visible clinically in the eye as orange retinal vessels and is strongly associated with death.

Complete blood count data can increase the accuracy of the diagnosis of severe malaria in children in high transmission settings.
