Nowadays parasitemia is the current knowledge to ensure a diagnosis of severe malaria but the detection of malarial retinopathy is a candicate diagnostic test for cerebral malaria, according to an article medio May 2006 issue of the The American Society of Tropical Medicine and Hygiene.
The original tittle of this article is MALARIAL RETINOPATHY: A NEWLY ESTABLISHED DIAGNOSTIC SIGN IN SEVERE MALARIA. According to the article, the presence of malarial retinopathy and its severity are related to disease outcomes such as prolonged coma and death in the patient. The recently data came from commonly misdiagnosed malaria in Africa, the research is backgrounded. In fact 90% African children face the burden of mortality from malaria that means exceeding a million deaths every year. In Malawi, a large-prospective study of children dying with cerebral malaria found that malarial retinopathy was better in distinguishing malarial. The researcher also planned to have a study of the retina and retinal blood vessels to visualize an infected microvasculature and its effect on neural tissue in vivo, according to the journal.
Nicholas A. Beare, F.R.C.Opth., of Royal Liverpool University Hospital, England, and colleagues studied the detection of retinopathy as a diagnostic test for cerebral malaria in subsequently fatal cases of coma. When using malarial retinopathy in diagnosing cerebral malaria wth any fatal coma, result a positive predictive value of 95% and negative predictive value of 90% compared with 77% when using parasitemia.
To a clinician detecting malarial retinopathy, its presence confirms a diagnosis of severe malaria, and in cerebral malaria the likelihood of death is strongly related to its severity. If retinopathy is absent in a child thought to have cerebral malaria, the clinician should bear in mind the possibility of other causes of coma, particularly if the coma is prolonged. This knowledge could improve care of critically ill patients with parasitemia in disease-endemic areas, and also improve the power of studies to assess interventions aimed at reducing the persistently high mortality of severe malaria.
