Cosmetic iris prosthesis and severe visual loss
Indian Journal of Ophthalmology. Case Reports, 2022 We report a case of a 39-year-old male who presented with bilateral severe diminution of vision, raised intraocular pressures despite maximal therapy, and corneal edema with endothelial decompensation six years following cosmetic iris prosthesis ...

Cobalt toxic optic neuropathy and retinopathy: Case report and review of the literature
American Journal of Ophthalmology Case Reports, 2020 Purpose: We detail a case of cobalt toxicity with visual and systemic complications, review the pathogenic process for the optic neuropathy and retinopathy, and discuss the controversy of metallic hip prosthesis. Observations: A 59-year-old female with a

Use-dependent increase in attention to the prosthetic foot in patients with lower limb amputation
Scientific Reports, 2022 Patients with lower limb amputation experience “embodiment” while using a prosthesis, perceiving it as part of their body. Humans control their biological body parts and receive appropriate information by directing attention toward them, which is called ...

Multichannel stimulation module as a tool for animal studies on cortical neural prostheses
Frontiers in Medical Technology, 2022 Intracortical microstimulation to the visual cortex is thought to be a feasible technique for inducing localized phosphenes in patients with acquired blindness, and thereby for visual prosthesis.
