ABSTRACT
Purpose: To describe a patient initially diagnosed with age-related macular degeneration (AMD) who was ultimately determined to have progressing pentosan polysulfate sodium (PPS)-associated maculopathy leading to secondary cystoid macular edema (CME) 10 years after cessation of PPS. Methods: An interventional case report is presented. Results: A 57-year-old woman diagnosed with AMD presented with unilateral worsening vision and metamorphopsia from CME. A detailed history showed a 3-year course of PPS, which had been discontinued 10 years previously. This led to the diagnosis of PPS-associated maculopathy. After topical NSAID and corticosteroid treatment failed, intravitreal bevacizumab resolved the symptoms. CME developed in the fellow eye 5 months later and also responded to bevacizumab. Conclusions: This case emphasizes the importance of a thorough review of past medication and medical histories in patients with pigmentary retinopathy and supports the use of antivascular endothelial growth factor therapy as an option to treat CME secondary to PPS-associated maculopathy.
