Researchers have developed a light-activatable prodrug nanomedicine for age-related macular degeneration (AMD) therapy. Through the intravenous injection of the nanomedicine and application of light irradiation to diseased eyes, anti-angiogenic and photodynamic combination therapy can be activated, offering a minimally invasive alternative for the treatment of AMD and other ocular disorders characterized by abnormal blood vessel growth.

3D eye scans can reveal vital clues about kidney health that could help to track the progression of disease, research suggests. The advance could revolutionize monitoring of kidney disease, which often progresses without symptoms in the early stages. Experts say the technology has potential to support early diagnosis as current screening tests cannot detect the condition until half of the kidney function has been lost.

As humans age, our eyes adjust based on how we use them, growing or shortening to focus where needed, and we now know that blurred input to the eye while the eye is growing causes myopia. It is so specific that the eye grows exactly to compensate for the amount and the direction of blur. Researchers have built a high-frequency ultrasonography system to measure eye size and how quickly eyes grow to better understand myopia and its contributing factors.

In Korea, workers are being provided with virtual reality (VR)-based safety training content to mitigate the increase in occupational accidents. However, the current training evaluation methods suffer from a lack of immediate feedback from participants for personal learning performance evaluation. To address this, a team of researchers has now developed a new framework that uses real-time biometric data during VR training for improving personalized safety and preventing occupational hazards.

Researchers have uncovered that tinnitus, an incurable persistent ringing or other sounds in the ears, might result from underlying auditory nerve damage that can’t be detected on conventional hearing tests. The work builds upon previous research into cochlear synaptopathy or ‘hidden hearing loss,’ a difficulty hearing in noisy environments despite showing normal results on hearing tests. The researchers hope these new findings into the mechanisms underlying tinnitus could lead to treatment options.
