SIP-SegNet: A Deep Convolutional Encoder-Decoder Network for Joint Semantic Segmentation and Extraction of Sclera, Iris and Pupil based on Periocular Region Suppression [PDF]
arXiv, 2020 The current developments in the field of machine vision have opened new vistas towards deploying multimodal biometric recognition systems in various real-world applications. These systems have the ability to deal with the limitations of unimodal biometric systems which are vulnerable to spoofing, noise, non-universality and intra-class variations.

A shell model of eye growth and elasticity [PDF]
, 2020 The eye grows during childhood to position the retina at the correct distance behind the lens to enable focused vision, a process called emmetropization. Animal studies have demonstrated that this growth process is dependent upon visual stimuli, while genetic and environmental factors that affect the likelihood of developing myopia have also been ...

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.

Targeting Connexin 43 in Retinal Astrocytes Promotes Neuronal Survival in Glaucomatous Injury
Glia, EarlyView.Astrocytes play an important role in glaucoma. These cells express Cx43, which can form gap junctions and hemichannels. This study shows that Cx43 deletion in astrocytes provides neuroprotection in glaucoma, possibly through hemichannel activation. ABSTRACT Astrocytes in the retina and optic nerve head play an important role in the pathogenesis of ...
