Comparing Continuum And Direct Fiber Models Of Soft Tissues: An Ocular Biomechanics Example Reveals That Continuum Models May Artificially Disrupt The Strains At Both The Tissue And Fiber Levels, Xuehuan He, Mohammad R. Islam, Fengting Ji, Bingrui Wang, Ian A. Sigal

Mechanical Engineering Faculty Publications

Collagen fibers are the main load-bearing component of soft tissues but difficult to incorporate into models. Whilst simplified homogenization models suffice for some applications, a thorough mechanistic understanding requires accurate prediction of fiber behavior, including both detailed fiber-level strains and long-distance transmission. Our goal was to compare the performance of a continuum model of the optic nerve head (ONH) built using conventional techniques with a fiber model we recently introduced which explicitly incorporates the complex 3D organization and interaction of collagen fiber bundles [1]. To ensure a fair comparison, we constructed the continuum model with identical geometrical, structural, and boundary …

The Relationship Between Spectral Signals And Retinal Sensitivity In Dendrobatid Frogs, Whitney G. Walkowski, Corinne L. Richards-Zawacki, William C. Gordon, Nicolas G. Bazan, Hamilton E. Farris

School of Graduate Studies Faculty Publications

Research on visually driven behavior in anurans has often focused on Dendrobatoidea, a clade with extensive variation in skin reflectance, which is perceived to range from cryptic to conspicuous coloration. Because these skin patterns are important in intraspecific and interspecific communication, we hypothesized that the visual spectral sensitivity of dendrobatids should vary with conspecific skin spectrum. We predicted that the physiological response of frog retinas would be tuned to portions of the visible light spectrum that match their body reflectance. Using wavelength-specific electroretinograms (ERGs; from 350-650 nm), spectrometer measurements, and color-calibrated photography of the skin, we compared retinal sensitivity and …

However, comparative studies between agents are limited. Our study aimed to compare the real-world SAE risks of bevacizumab, ranibizumab, and aflibercept users.

METHODS: This retrospective cohort study identified new bevacizumab, ranibizumab, and aflibercept users in a multi-institutional database in Taiwan between 2014 and 2019. Inverse probability of treatment weights (IPTW) with propensity scores was conducted to achieve homogeneity among …


A Unilateral Myopic Shift Secondary To Sturge-Weber Syndrome Results In Refractive Amblyopia Of The Fellow Eye In A Pediatric Patient, Mckenzie Stewart, Christina Twardowski Nov 2024

A Unilateral Myopic Shift Secondary To Sturge-Weber Syndrome Results In Refractive Amblyopia Of The Fellow Eye In A Pediatric Patient, Mckenzie Stewart, Christina Twardowski

Posters

A 4-year-old patient with unilateral glaucoma secondary to Sturge-Weber Syndrome causes a myopic shift. The fellow healthy eye maintains high hyperopia resulting in anisometropic refractive amblyopia, requiring occlusion therapy. It is well documented that a glaucomatous high IOP causes an expansion of the globe due to excessive plasticity of collagen fibers in pediatric eyes. The elongated axial length induces myopic shifts. In this patient, the myopic shift in her glaucomatous eye resulted in a unilateral high hyperopic refractive error in the fellow eye with normal ocular health. This anisometropia is enough to cause amblyopia in the hyperopic eye. In past …

Minocycline-Induced Retinal Pigment Epithelium Hyperpigmentation Masquerading As Age-Related Macular Degeneration: Case Presentation And Proposed Mechanism, Michael D. Yu, Nikhil Bommakanti, Yoshihiro Yonekawa, Jose S. Pulido

Wills Eye Hospital Papers

PURPOSE: We describe the case of an 80-year-old man with bilateral minocycline-induced retinal pigment epithelium (RPE) hyperpigmentation, which initially masqueraded as AMD. Secondarily, using multimodal imaging features, we propose a mechanism for the development of minocycline-induced RPE hyperpigmentation.

OBSERVATIONS: The patient was referred with concern for AMD given the presence of macular drusenoid deposits on optical coherence tomography. However, funduscopic evaluation showed dense granular parafoveal hyperpigmentation, with a diffuse slate-colored hyperpigmentation throughout the peripheral fundus. Short-wavelength fundus autofluorescence of the macula disclosed no irregularities (as would be expected with drusen) while on near-infrared reflectance (NIR) imaging, numerous hyperreflective foci were …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Inflammation in the eye is tightly regulated to prevent vision impairment and irreversible blindness. Emerging evidence shows that immune cells are specifically recruited to the lens capsule in response to autoimmune uveitis, yet the potential that they have a role in regulating this inflammatory disease remained unexplored. Here, an immunolocalization approach combined with high-resolution confocal microscopy was used to investigate whether the immune cells that become stably associated with the lens capsule in the eyes of C57BL/6J mice with experimental autoimmune uveitis (EAU) have an immunoregulatory phenotype. These studies revealed that during the acute phase of uveitis, at day 18 …
