Advances in visual rehabilitation through technology and research

Advancements in ophthalmology are providing new avenues for visual rehabilitation through both clinical research and assistive technologies. In Brazil, the Brazilian Council of Ophthalmology (CBO) has mapped 95 specialized rehabilitation centers (CERs) available through the Unified Health System (SUS). These centers, distributed across all regions of the country, aim to restore autonomy to individuals with low vision or blindness, though the CBO notes that many patients and even health professionals remain unaware of these free services.

Technological integration is also playing a critical role. Artificial intelligence is being utilized in tools such as smart canes that use voice commands to detect obstacles, and audio description systems that analyze environments to assist users.

On the research front, Botond Roska and José-Alain Sahel have been awarded the António Champalimaud Prize 2026 for their work in restoring vision. Their research utilizes optogenetics to make certain retinal cells light-sensitive, effectively replacing the function of lost photoreceptors. This translational research has moved from animal models to human clinical trials, offering hope for those suffering from hereditary retinal dystrophies and macular degeneration.
