[Fortuitous detection of composite heterozygous S/C sickle cell disease]

Composite S/C sickle cell disease accounts for 20%-30% of major sickle cell syndromes. We report a case of fortuitous detection of composite heterozygous S/C sickle cell disease in the context of retinal detachment. The patient had been hospitalized in the Department of Ophthalmology for treatment-resistant decreased visual acuity detected 06 months before. The patient's clinical history was marked by total hip replacement (THR) twelve years before. Our study highlights the wide clinical variability of sickle cell disease underlying the importance of early screening and adapted clinical monitoring of patients at-risk, in order to avoid its evolution toward irreversible organic sequelae such as sickle cell retinopathy.
