PURPOSE: Sickle cell trait affects 8% of African Americans. Once believed to represent a benign carrier state, it has been linked to an increased risk of several of the pathological conditions that arise in sickle cell disease in at-risk individuals with hematologic and vascular comorbidities. Macular infarction is a known complication of sickle cell disease; this article illustrates this unique presentation in a patient with sickle cell trait.
METHODS: Case report.
PATIENT: A 74-year-old African American man presented with the complaint of a central scotoma of the right eye.
RESULTS: Multimodal retinal imaging identified central macular infarction with severe inner retinal atrophy. Laboratory testing confirmed the presence of sickle cell trait. Other pertinent positives included low levels of protein C and protein S, untreated obstructive sleep apnea, and elevated levels of homocysteine in the setting of alcoholic liver cirrhosis and chronic kidney disease.
CONCLUSION: Ocular manifestations of sickle cell trait have most frequently been reported in individuals with systemic medical comorbidities that predispose to erythrocyte sickling and vaso-occlusive disease. This case identifies a novel complication of sickle cell trait disorder, macular infarction, in a patient with comorbid associations.
