Headaches and blurred vision in patients with cyanotic congenital heart disease and secondary erythrocytosis may be attributed to hyperviscosity and traditionally were treated with phlebotomy. In the current era, phlebotomy is rarely performed in these patients except in cases of hemoptysis or hyperviscosity symptoms. We report a case of a patient with a history of complex cyanotic congenital heart disease and secondary erythrocytosis who presented with headache and visual changes. He was found to have bilateral papilledema and increased intracranial pressure. Reduction of intracranial pressure with acetazolamide therapy led to alleviation of headache and visual changes. This demonstrates the need for formal ophthalmologic evaluation of these patients to assess other treatable causes of headache and visual changes before considering phlebotomy.
