Sickle cell disease (SCD) is characterized by vaso-occlusive crisis. In the eye, central retinal artery occlusion (CRAO) is a rare complication in SCD, with only 1 previous report of bilateral, concurrent CRAO. We report a case of bilateral, concurrent CRAO in a patient with SCD, possibly precipitated by the use of phosphodiesterase 5 inhibitors.
A 37-year-old African American woman with a known medical history significant for SCD and pulmonary arterial hypertension who was receiving treatment with tadalafil, a phosphodiesterase 5 inhibitor, developed bilateral, concurrent CRAO that persisted after exchange transfusion.
Conclusions and Relevance
Bilateral CRAO secondary to SCD is extremely rare, with only 1 previous case report in the literature. The use of phosphodiesterase 5 inhibitors is an additional risk factor and may have contributed to the development of concurrent CRAO in this patient.
