Intrascleral and Peripheral Retinal Crystals in Bietti Crystalline Dystrophy

Intrascleral crystal distribution may aid in broadening the phenotypic spectrum of BCD, supporting more accurate diagnosis and contributing to the understanding of its pathophysiology. UWF and multimodal imaging provide complementary insights into BCD extent and crystal localization. Infrared reflectance outperforms pseudocolor photography for crystal detection, while UWF-OCT expands structural evaluation into the periphery, potentially improving monitoring strategies.
