PENTOSAN POLYSULFATE SODIUM-INDUCED PIGMENTARY MACULOPATHY WITH NONLEAKING CYSTOID MACULAR EDEMA SUCCESSFULLY TREATED WITH ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY.

PURPOSE: To report a case of nonleaking cystoid macular edema (CME) associated with pentosan polysulfate sodium (PPS)-induced pigmentary maculopathy.

METHODS

Multimodal imaging, including optical coherence tomography, fundus photography, autofluorescence, and fluorescein angiography, was used to substantiate our diagnosis, further characterize the cystoid macular edema showed by our patient and to monitor the response to treatment.

RESULTS

A 59-year-old woman was referred for decreased visual acuity and bilateral macular edema. She had been treated for interstitial cystitis with PPS for 10 years. Multimodal imaging showed the characteristic features of PPS-induced pigmentary maculopathy. Moreover, fluorescein angiogram showed nonleaking cystoid macular edema in both eyes. She was treated successfully with intravitreal injections of bevacizumab.

CONCLUSION

To our knowledge, this report is the first to demonstrate that PPS-associated cystoid macular edema can be nonleaking on fluorescein angiography and responds well to intravitreal anti-vascular endothelial growth factor injections.
