Acute, bilateral, concurrent central retinal artery occlusion in sickle cell disease after use of tadalafil (Cialis)
Abstract
IMPORTANCE
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.
OBSERVATIONS
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.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
