Interstitial Cystitis, Pigmentary Maculopathy, Pigmentary Retinopathy
Conditions
Brief summary
The purpose of this study is to evaluate incidence and prevalence rates of the study endpoints (pigmentary maculopathy \[PM\]/ pigmentary retinopathy \[PR\]/Any, PM/PR/ pentosan polysulfate sodium \[PPS\], and PM/PR/Non-PPS) in relation to PPS exposure, and in participants with interstitial cystitis (IC) but not exposed to PPS; changes in visual acuity (VA) over time; participant treatment journey leading to PPS treatment, and potential risk factors associated with the occurrence of PM/PR/PPS.
