This implant can restore sight for patients with macular degeneration
視力回復インプラントのニュースを見て、視覚をパイプラインとして捉え直した話 網膜の細胞が死ぬ地図状萎縮（geographic atrophy）に対して、PRIMAインプラントが視力回復の可能性を示したというニュースがありました。欧州では承認済み、米国はFDA承認待ち。世界で500万人以上が該当すると言われている進行型AMDの話で、素直にすごい進歩だと思います。 ただ、このニュースを読んで考えたのは別の角度のことでした。視覚は入力（網膜）→伝達（視神経）→統合（視覚野）というパイプラインとして捉えられます。インプラントが主に扱うのは入力層です。そして統合層には、別のクラスの問題が残ります。 左右の目から届く2つの像を1つにまとめる両眼視が機能しない状態が、弱視（lazy…
A new implant has the potential to restore sight for patients with macular degeneration, a condition that affects over 5 million people worldwide. This device targets the input layer of the visual pipeline, which is responsible for receiving images from both eyes. However, even without significant abnormalities in the eye, one eye's input can be suppressed in the brain, leading to conditions such as lazy eye and crossed eyes.
Traditional glasses act as a workaround by physically blocking the image from the weaker eye, but recent approaches focus on presenting simultaneous stimuli to both eyes and gradually training the brain to integrate the visual information. AmblyoPunch is a VR game designed for the Meta Quest, which uses Gabor patterns and other tasks to help train the brain to integrate the visual input from both eyes.
The game adjusts the difficulty based on the user's performance, ensuring an adaptive and personalized experience. It is crucial to consult with eye care professionals before using this training method, as it is not a replacement for medical treatment or therapy.
