Advanced Science, EarlyView.An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

Response of the anterior sclera to accommodation in myopes and emmetropes [PDF]
, 2016 • The biomechanical properties of the sclera are documented to be altered in eyes with myopia, with the myopic sclera thought to be more susceptible to deformation from otherwise normal ocular forces.\ud \ud • The close anatomical and functional ...

Journal of Applied Polymer Science, EarlyView.PLA and PCL ocular implants prepared by tape casting and electrospinning provide sustained dexamethasone release with distinct release profiles governed by polymer type and processing method. The relationship between polymer structure, degradation behavior, and drug release demonstrates the potential of these fabrication techniques for controlled ...

Understanding the spacing of placodes in the eye: A comparative study across age and species
The Anatomical Record, EarlyView.Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Porcine sclera dissected by scalpel blades.
, 2013 Strips in the lower and upper sides of the figure are peripapillary sclera and sclera near the limbus, respectively. The four strips of sclera between them were used for the measurement.

Sensory Neuroscience, EarlyView.Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

The Dynamic Scleral Extracellular Matrix Alterations in Chronic Ocular Hypertension Model of Rats
Frontiers in Physiology, 2020 Intraocular pressure (IOP) generates stress and strains in the laminar cribrosa and sclera, which may affect the development and progression of glaucoma. Scleral stiffness and material components have changed under elevated IOP.
