Retinitis pigmentosa (RP) displays a broad range of phenotypic variations, often overlapping with acquired retinal diseases. Timely recognition and differentiation of RP masquerades is paramount due to the treatable nature of many such conditions. This review seeks to present examples of pseudo-RP cases and provide a comprehensive overview of RP masquerades. We first present two pseudo-RP cases, including comprehensive clinical histories and multimodal retinal imaging, to highlight the important role of accurate diagnoses that subsequently steered effective intervention. Subsequently, we conduct an in-depth review of RP masquerades to provide valuable insights into their key distinguishing features and management considerations. The recent approval of ocular gene therapy and the development of investigational gene-based treatments have brought genetic testing to the forefront for RP patients. However, it is important to note that genetic testing currently lacks utility as a screening tool for inherited retinal diseases (IRDs), including RP. The integrity of a precise clinical assessment remains indispensable for the diagnosis of both RP and RP masquerade conditions, thereby facilitating prompt intervention and appropriate management strategies.
