Evaluating anterior corneal surface using Placido ring mires for irregular astigmatism in refractory corneal subepithelial infiltrates after adenoviral conjunctivitis

BMC Ophthalmology
Background Corneal subepithelial infiltrates (SEIs) are characteristic clinical findings of adenoviral keratoconjunctivitis (AKC). In eyes with SEIs, both corneal opacity and irregular astigmatism may interfere with vision. However, irregular astigmatism

A Plant Photoregulator‐Inspired S‐Type Heterojunction System for Diabetic Keratopathy via Tri‐Modal Light‐Driven Immunometabolic Reprogramming, Tissue Repair, and Antibacterial Activity

Advanced Science, EarlyView.
To address the multifaceted imbalance in diabetic keratopathy, a light‐responsive biomimetic platform (WCNx‐Rh2) is developed and integrates glucose degradation, immune modulation, and antibacterial defense through a designed heterojunction and screened immunomodulator. WCNx‐Rh2 reduces AGEs/ROS and inflammatory signaling, reprogramming dendritic cells
