Summary
Diagnosing cerebral malaria (CM) is crucial. Retinal examination, revealing specific changes like patchy whitening, accurately identifies CM even with asymptomatic Plasmodium falciparum parasitemia.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Neurology
Background:
- Accurate diagnosis of cerebral malaria (CM) is vital for patient management and research.
- Distinguishing CM from other causes of coma in malaria-endemic regions is challenging due to common asymptomatic parasitemia.
Purpose of the Study:
- To highlight the diagnostic utility of specific retinal findings in identifying cerebral malaria.
- To advocate for routine retinal examination in comatose patients with suspected CM.
Main Methods:
- Ophthalmoscopic examination to identify characteristic retinal changes.
- Analysis of the specificity of retinal findings for malarial etiology.
Main Results:
- Patchy retinal whitening and focal changes in vessel color are highly specific for malarial encephalopathy.
- White-centered retinal hemorrhages are common but less specific indicators.
Conclusions:
- Retinal examination is a valuable tool for diagnosing cerebral malaria.
- Nonspecialist clinicians can be trained to perform ophthalmoscopy for CM diagnosis.
- Routine retinal assessment should be integrated into the evaluation of comatose patients with suspected CM.

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
