Recent studies have implicated long-term pentosan polysulfate use with vision loss from a newly described macular condition. Affected patients report difficulty with reading and adjusting to dim lighting, and they occasionally develop severe visual disability. Macular changes resemble those seen in age-related macular degeneration, potentially leading to misdiagnosis. The objectives of this Current Commentary are to summarize studies evaluating the association between pentosan polysulfate use and macular disease, to educate pentosan polysulfate prescribers about the clinical manifestations of this condition, and to provide recommendations for screening at-risk patients.

Background: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a multifactorial, chronic syndrome involving urinary frequency, urgency, and bladder discomfort. These IC/BPS symptoms can significantly impact individuals' quality of life, affecting their mental, physical, sexual, and financial well-being. Individuals sometimes rely on peer-to-peer support to understand the disease and find methods of alleviating symptoms.

Purpose: Although the mechanism underlying interstitial cystitis/bladder pain syndrome (IC/BPS) remains unclear, oxidative stress is suggested to be implicated in IC/BPS development. Sea buckthorn (SB; L.) contains several compounds with antioxidant properties.

Purpose: To evaluate prevalence and incidence rates of pigmentary maculopathy and retinopathy (PM/PR), and visual acuity (VA) changes in patients exposed to pentosan polysulfate sodium (PPS) and in patients with interstitial cystitis (IC) not exposed to PPS.
Methods: This is a retrospective cohort study (January 2015-March 2021) which included adult de-identified patients from the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) and Komodo Health database. Three patient cohorts were identified: two PPS-exposed patient cohorts, and Non-PPS-exposed IC patient cohort.

Macular degeneration is a leading cause of irreversible vision loss, significantly impacting quality of life. To enhance clinical practice and reduce the risk of drug-related macular degeneration, we analyzed drug-related trends using real-world data. Disproportionality analysis of adverse event reports from the FDA Adverse Event Reporting System (FAERS, 2004-2023) identified 67,683 cases involving 1402 drugs.

Purpose: To report a case of pentosan polysulfate sodium (PPS) maculopathy with cystoid macular edema (CME) with relatively low cumulative PPS exposure and a history of concurrent hydroxychloroquine use.
Observations: A 46-year-old female was treated with PPS daily for 10 years, and hydroxychloroquine intermittently over a span of five years, actively taking hydroxychloroquine for a sum of three years during PPS therapy. Despite a low risk for toxicity based on the cumulative exposure to either medication, fundoscopic examination and multimodal imaging revealed severe PPS maculopathy with CME two and a half years post-PPS cessation.
