We still don’t have a computational explanation of phosphenes. 👁️ 🧠
That’s a problem if you’re trying to build visual prosthetics.

What happens when a neural network controls electrical stimulation delivered directly to the brain?
In our new JNE paper we answer an important question: how do we know these models are safe?

A Surrey-based study details how the #retina can build its structure from one type of stem cell: "Our simulations show how genetically identical cells can, through intrinsic bias and chance, self-organise into the retina's highly ordered layers." 🧠 🧪

🚨 Breakthrough alert: A new study in the NEJM reports that the PRIMA subretinal implant helped restore meaningful central vision in ~80% of participants with advanced geographic atrophy (an untreatable form of #AMD).

What happens years after the implant?
A new study from Cleveland Clinic follows 13 Argus II users long-term. None still use the device - but nearly half say they’d do it again. A powerful reminder of both the promise and the burden of early #BionicVision.

🚨 New preprint: Researchers from ETH Zurich, UMH Elche, and UCSB report the first data-driven control of a visual cortical prosthesis in a blind human.
Deep learning enabled more efficient, stable stimulation - and argues for closed-loop designs.

Diagram of the experimental setup for measuring electrically evoked neural activity. A stimulation pattern is chosen across electrodes on a Utah array (left). Selected electrodes deliver 167 ms trains of 50 pulses at 300 Hz (middle left), sent via stimulator and amplifier into the visual cortex of a participant (middle). Neural signals are recorded before and after stimulation across all channels, producing multi-unit activity traces (MUAe). The difference between pre- and post-stimulation activity (ΔMUAe) is computed (middle right) and visualized as a heatmap across electrodes, showing localized increases in neural responses (right).
Many in #BionicVision have tried to map stimulation → perception, but cortical responses are nonlinear and drift day to day.
So we turned to 🧠 data: >6,000 stim-response pairs over 4 months in a blind volunteer, letting a model learn the rules from the data.

A group of surgeons in blue scrubs and surgical masks are performing a procedure in a clinical wetlab setting. Dr. Muqit (seated) operates under a ZEISS ARTEVO® 850 surgical microscope, with Dr. others observing and assisting nearby. A large monitor and medical equipment are visible in the background, along with surgical instruments on a sterile table. The environment is dimly lit, with overhead lights providing focused illumination on the surgical field.
A surgeon in blue scrubs, surgical gloves, and a hair cover is seated and operating under a ZEISS ARTEVO® 850 surgical microscope. He is performing a delicate procedure on a blue surgical model using forceps, while another masked assistant supports from behind. The operating table is covered with a sterile green drape, and medical tubing and instruments are visible around the setup. The environment is dimly lit, highlighting the precision of the surgical training.
A wide view of a surgical training room shows multiple surgeons in blue scrubs and masks working around a ZEISS ARTEVO® 850 digital microscope. One seated surgeon is actively operating on a subretinal surgery model, while others observe and assist. A large overhead visualization arm and a table with imaging and surgical equipment are prominently visible. The lighting is dim except for the illuminated surgical field, emphasizing the precision and focus of the wetlab environment.
Two surgeons in blue scrubs and surgical caps are seated at a ZEISS ARTEVO® 850 digital microscope in a dimly lit operating room. A large monitor displays a high-resolution OCT scan, showing detailed cross-sections of ocular tissue. A green surgical drape, tubing, and imaging equipment are visible around the operating station. The scene highlights the integration of real-time imaging in subretinal surgical training.

Prof. da Cruz argues the real legacy of first-gen devices is:
– safety + biotolerance
– validated test methods (FLORA, navigation tasks)
– a foundation to build on
We know how to test now.
We just need better tools.

In a sobering but essential read, Prof. da Cruz reflects on the rise, retreat, and future of retinal prostheses:
“Performance didn’t transfer to daily life—and the field stalled.”
