Chronic central serous chorioretinopathy responsive to rifampin.

PURPOSE

The purpose of this was to describe the clinical improvement of chronic central serous chorioretinopathy in a patient treated with rifampin for tuberculosis.

METHODS

A 54-year-old Hispanic man with a distant history of pulmonary tuberculosis presented with reduced vision in the right greater than left eye for over 1 year. He had diffuse chorioretinopathy in both eyes and a serous retinal detachment in his right eye. The findings were most consistent with chronic central serous chorioretinopathy, although tuberculosis -related choroiditis could not be excluded. Treatment with multidrug antituberculosis medications, including rifampin, resulted in the reduction in leakage and resolution of subretinal fluid. Fluid recurred on cessation of all medications and resolved again with retreatment. Monotherapy with rifampin maintained the absence of fluid.

DISCUSSION

This case represents the first report of chronic central serous chorioretinopathy responding to systemic therapy with rifampin. We hypothesize that the clinical response observed is secondary to induction of cytochrome P450 with increased hepatic metabolism of endogenous corticosteroids and a reduction in systemic cortisol levels.
