TL;DR: It is found that the use of short pulse durations with no interphase gap at high frequency increases the differential response of RGCs, offering better opportunities for selective activation of D1 cells.

TL;DR: In this article, a tool is used in charging an implantable medicine delivery device and an apparatus and a method for charging the device is provided. But the tool may include, for example, a needle inserted through a charging port 152 of the device.

TL;DR: In this article, a method of focused phosphene generation through deeper intermediate retinal cellular electrical stimulation to the exclusion of direct ganglion electrical stimulation comprises the steps of positioning a stimulating electrode in the vicinity of retinal tissue; and applying a long duration stimulation signal to the electrode such that deeper-intermediate retinal cells are preferentially stimulated over the proximal overlying surface axons.

TL;DR: Stem cell-based therapies that introduce healthy tissue into the eye have been shown to restore or rescue the degenerated retina and improve vision in animal models as discussed by the authors, which is a promising treatment for retinal diseases.

TL;DR: A modified surgical technique was performed in a 43-year-old male with retinitis pigmentosa who underwent strabismus surgery in that eye at age 8, minimizing the risk of postoperative conjunctival erosion and device exposure.
