Multimodal imaging in retinitis pigmentosa related to the EYS gene.

Purpose: This study aimed to characterize retinitis pigmentosa associated with the eyes shut homolog gene, which causes hereditary retinal degeneration.

Methods: The anatomical and functional findings of retinitis pigmentosa in patients with variants of the eyes shut homolog gene were characterized and compared using multimodal imaging and genetic analysis of the variants. Clinical data such as visual acuity, lens status, and refraction were obtained from medical records.

Perception and satisfaction of blind individuals regarding an electronic cane prototype with a wearable haptic device.

Purpose: This study aimed to evaluate the perception and degree of satisfaction of blind individuals regarding an electronic cane prototype with a wearable haptic interface.

Methods: Two scenarios with different obstacles were created to conduct tests with the canes (the user's cane and the prototype one). The perception and satisfaction of participants regarding the electronic cane were assessed using a questionnaire, the number of collisions during the tests, and the time each individual took to complete the course in each scenario.

Expanding the Phenotypic and Genotypic Spectrum of Bietti Crystalline Dystrophy.

The rare form of retinal dystrophy, Bietti crystalline dystrophy, is associated with variations in , a member of the cytochrome P450 family. This study reports patients affected by typical and atypical Bietti crystalline dystrophy, expanding the spectrum of this disease. This is an observational case series of patients with a clinical and molecular diagnosis of Bietti crystalline dystrophy that underwent multimodal imaging.
