715. 对比度与近视对人眼调节功能的影响
from 知为谁 · host 知为谁
这项研究探讨了人类视觉调节功能与对比度及近视之间的复杂关系。研究发现，当物体对比度增加时，人眼的晶状体调节、眼球聚合和瞳孔收缩（即近视三联症）会显著增强，且该过程受视网膜ON/OFF通路的差异性驱动。近视患者在这些调节反应中表现出更强的功能增强，并伴有明显的隐内斜视倾向。此外，研究揭示了眨眼时长与瞳孔收缩之间呈U形曲线关系，而近视会干扰这一正常的生理响应。作者提出，过度的瞳孔收缩可能通过减少视网膜照度，进而成为驱动近视加深的一个潜在生物学机制。内容来源：https://www.cell.com/cell-reports/fulltext/S2211-1247(26)00016-1
