Robust Sclera Recognition System With Novel Sclera Segmentation and Validation Techniques

, 2017
Sclera blood veins have been investigated recently as a biometric trait which can be used in a recognition system. The sclera is the white and opaque outer protective part of the eye.

A Topographical Anatomical Description of the Orbit of the Alpaca, Vicugna pacos

Veterinary Ophthalmology, Volume 29, Issue 6, November 2026.
ABSTRACT Objective To describe the gross anatomy of the orbita in Huacaya alpacas, identify species‐specific features, and provide comparative anatomical information relevant to clinical ophthalmic practice. Animals Studied Nine heads from postmortem donated Huacaya alpacas were used. Procedures Two skulls were evaluated to characterize the orbita, and

An unsupervised approach for eye sclera segmentation

, 2018
We present an unsupervised sclera segmentation method for eye color images. The proposed approach operates on a visible spectrum RGB eye image and does not require any prior knowledge such as eyelid or iris center coordinate detection.

Form-deprivation myopia induces decreased expression of bone morphogenetic protein-2, 5 in guinea pig sclera

International Journal of Ophthalmology, 2015
AIM: To identify the presence of various bone morphogenetic proteins (BMPs) and their receptors in normal sclera of human, rat and guinea pigs, and to determine whether their expression changed with form-deprivation myopia (FDM) in guinea pig sclera ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, Volume 73, Issue 9, September 2026.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Inhibition of VEGF‐Induced Angiogenesis and Vascular Leakage by Bicistronic Co‐Expression of Aflibercept and COMP‐Ang1

Advanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.
A bicistronic rAAV8 vector encoding Aflibercept (Afb) and COMP‐cAng1 simultaneously coordinates VEGF clearance and Tie2‐mediated vessel maturation. In a 3D angiogenesis‐on‐a‐chip model, rAAV8‐Afb/cAng1 effectively reverses pathological barrier breakdown under clinical disease‐mimicking challenges.

Human sclera maintains common characteristics with cartilage throughout evolution.

, 2008
BackgroundThe sclera maintains and protects the eye ball, which receives visual inputs. Although the sclera does not contribute significantly to visual perception, scleral diseases such as refractory scleritis, scleral perforation and pathological myopia

A Whole‐Head Finite Element Model for Electrical Neuromodulation via Visual Brain‐Machine Interfaces

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A multimodal, personalized head model is presented that integrates the entire visual pathway with surrounding tissues to simulate electrical stimulation of the optic nerve. In vivo validation in humans and goats, plus systematic component‐elimination analysis, demonstrates the high accuracy of the comprehensive model.
