An unusual case of rapid resolution of bilateral vitelliform deposits after discontinuation of pentosan polysulfate sodium

Abstract

Purpose: To report the structural and functional changes in a 67-year-old male with pentosan polysulfate sodium (PPS) maculopathy with a progressive resolution of bilateral vitelliform lesions after PPS cessation. Observations: The patient was initially seen after taking daily PPS for over 26 years. Three months after discontinuing PPS, the bilateral vitelliform lesions identified on spectral-domain optical coherence tomography (SD-OCT) at initial consultation had completely resolved. Bilateral resolution of vitelliform lesions was associated with a decline in best-corrected visual acuity, and ellipsoid zone disruption on SD-OCT. Conclusions and importance: Several PPS maculopathy phenotypes have been previously described including vitelliform lesions. Our case highlights that discontinuing PPS may lead to rapid resolution of vitelliform lesions in PPS maculopathy and may be associated with a rapid reduction in vision.
