Aerobic Glycolysis Is Essential For Normal Rod Function And Controls Secondary Cone Death In Retinitis Pigmentosa, Lolita Petit, Shan Ma, Joris Cipi, Shun-Yun Cheng, Marina Zieger, Nissim Hay, Claudio Punzo 2018 University of Massachusetts Medical School

Aerobic Glycolysis Is Essential For Normal Rod Function And Controls Secondary Cone Death In Retinitis Pigmentosa, Lolita Petit, Shan Ma, Joris Cipi, Shun-Yun Cheng, Marina Zieger, Nissim Hay, Claudio Punzo

Open Access Articles

Aerobic glycolysis accounts for approximately 80%-90% of glucose used by adult photoreceptors (PRs); yet, the importance of aerobic glycolysis for PR function or survival remains unclear. Here, we further established the role of aerobic glycolysis in murine rod and cone PRs. We show that loss of hexokinase-2 (HK2), a key aerobic glycolysis enzyme, does not affect PR survival or structure but is required for normal rod function. Rods with HK2 loss increase their mitochondrial number, suggesting an adaptation to the inhibition of aerobic glycolysis. In contrast, cones adapt without increased mitochondrial number but require HK2 to adapt to metabolic ...


Screening Amblyopic Risk Factors In A Pediatric Population Using An Automated Vision Screener, Rebecca Dawn Slominski 2018 Valparaiso University

Screening Amblyopic Risk Factors In A Pediatric Population Using An Automated Vision Screener, Rebecca Dawn Slominski

Evidence-Based Practice Project Reports

Amblyopia is the most common visual disorder in children and is potentially curable if detected early and treated properly in the first few years of life. Amblyopia is the leading cause of monocular vision loss in children (Bradfield, 2013). It is a developmental neuroplasticity which derives from birth causing structural and functional changes in the eye and brain. With this structural and functional disruption, visual blur occurs due to refractive amblyopia, strabismic amblyopia, cataracts (form-deprivation amblyopia), or a combination of any of these (Solebo, Cumberland, & Rahi, 2015). Refractive errors related to amblyopia can also occur. The purpose of this evidence-based ...


The Comparison Of Spectral Domain Optical Coherence Tomography (Sd-Oct) To Histopathology In A Patient With Diffuse Macular Drusen, Harold Salmons, Ralph Eagle, MD 2018 Thomas Jefferson University

The Comparison Of Spectral Domain Optical Coherence Tomography (Sd-Oct) To Histopathology In A Patient With Diffuse Macular Drusen, Harold Salmons, Ralph Eagle, Md

Department of Pathology Honors Program Student Research Symposium

Background: Spectral Domain Optical Coherence Tomography (SD-OCT) has become a gold standard technique in ophthalmologic practice, and has revolutionized the diagnosis and treatment of retinal disease. As SD-OCT uses low interference interferometry and mathematical algorithms to produce detailed theoretical cross-sectional images of the retina, it is crucial to examine correlations between SD-OCT images and their corresponding histopathologic slides.

Methods: In the present study, careful correlative light microscopy was performed on the eye that was enucleated from an elderly patient who had a uveal melanoma and early agerelated macular degeneration evident clinically as soft drusen. SD-OCT was performed prior to enucleation ...

Introduction

Radiation therapy is often used for tumors of the optic nerve. The challenge with irradiating tumors surrounding structures associated with the eye is the risk of exposing the optic nerve, or other structures important to maintaining vision to potentially damaging radiation.

Fractionated stereotactic radiotherapy (FSRT) is commonly used for the treatment of optic nerve sheath meningiomas (ONSMs) for vision preservation. However, long term visual data in the literature is limited. We investigated visual outcomes in 27 patients with ONSMs after FSRT.


Differential Diagnosis Of Pan-Uveitis: Behçet’S Disease, Peter Blosser, Remil Simon, Courtney Ridner 2018 East Tennessee State University

Differential Diagnosis Of Pan-Uveitis: Behçet’S Disease, Peter Blosser, Remil Simon, Courtney Ridner

Appalachian Student Research Forum

This report describes the case of a 56-year-old man who presented with blurry vision, increased intraocular pressure, and conjunctival injection after posterior chamber intraocular lens implantation. Initially post-operative endophalmitis and foreign body inflammation were considered as differential diagnoses, but after further examination pan-uveitis was diagnosed. Uveitis is an ocular finding that may indicate several diseases, one of which is Behçet’s Disease. During the interview, the patient mentioned a history of apthous ulcers and genital ulcers which then lead to the clinical diagnosis of Behçet’s Disease. This report emphasizes that Behçet’s Disease is rare in Caucasians. Therefore, is ...

PURPOSE: To examine whether herpes zoster antigen (also called varicella-zoster virus antigen) was detectable in temporal artery biopsies taken from individuals with giant cell arteritis (GCA).

DESIGN: Retrospective comparative case series.

METHODS: Sections of formalin-fixed paraffin-embedded temporal arteries were examined first by hematoxylin-eosin (H&E) staining to establish the diagnosis of GCA. Adjacent sections of the same biopsy were then examined by immunohistochemistry, using 2 different monoclonal antibodies against a major antigen of varicella-zoster virus called gE. Pathologic specimens were obtained from patients cared for at the University of Iowa and Washington University in St. Louis ophthalmology clinics.

RESULTS: The ...

Objective: Limited attention has been given to ocular injuries associated with traumatic brain injury (TBI). The retina is an extension of the central nervous system and evaluation of ocular damage may offer a less-invasive approach to gauge TBI severity and response to treatment. We aim to characterize acute changes in the mouse eye after exposure to two different models of TBI to assess the utility of eye damage as a surrogate to brain injury.

Methods: A model of blast TBI (bTBI) using a shock tube was compared to a lateral fluid percussion injury model (LFPI) using fluid pressure applied directly ...

A Model For Investigating Developmental Eye Repair In Xenopus Laevis, Cindy X. Kha, Philip H. Son, Julia Lauper, Kelly Ai-Sun Tseng

Life Sciences Faculty Publications

Vertebrate eye development is complex and requires early interactions between neuroectoderm and surface ectoderm during embryogenesis. In the African clawed frog, Xenopus laevis, individual eye tissues such as the retina and lens can undergo regeneration. However, it has been reported that removal of either the specified eye field at the neurula stage or the eye during tadpole stage does not induce replacement. Here we describe a model for investigating Xenopus developmental eye repair. We found that tailbud embryos can readily regrow eyes after surgical removal of over 83% of the specified eye and lens tissues. The regrown eye reached a ...

Retinitis pigmentosa (RP) is a major cause of blindness that affects 1.5 million people worldwide. Mutations in cyclic nucleotide-gated channel β 1 (CNGB1) cause approximately 4% of autosomal recessive RP. Gene augmentation therapy shows promise for treating inherited retinal degenerations; however, relevant animal models and biomarkers of progression in patients with RP are needed to assess therapeutic outcomes. Here, we evaluated RP patients with CNGB1 mutations for potential biomarkers of progression and compared human phenotypes with those of mouse and dog models of the disease. Additionally, we used gene augmentation therapy in a CNGβ1-deficient dog model to evaluate potential ...

Purpose: Progenitor cells of the limbal epithelium reside in a discrete area peripheral to the more differentiated corneal epithelium and maintain tissue homeostasis. What regulates the limbal-corneal epithelial boundary is a major unanswered question. Ephrin-A1 ligand is enriched in the limbal epithelium, whereas EphA2 receptor is concentrated in the corneal epithelium. This reciprocal pattern led us to assess the role of ephrin-A1 and EphA2 in limbal-corneal epithelial boundary organization.

Methods: EphA2-expressing corneal epithelial cells engineered to express ephrin-A1 were used to study boundary formation in vitro in a manner that mimicked the relative abundance of these juxtamembrane signaling proteins in ...


Inflammation In The Pathogenesis Of Diabetic Retinopathy, Haoshen Shi 2018 Wayne State University

Inflammation In The Pathogenesis Of Diabetic Retinopathy, Haoshen Shi

Wayne State University Dissertations

The general purpose of these studies is to investigate inflammation in diabetic retinopathy in an effort to identify key intervention points to develop as treatments. Firstly, we showed that the neuropeptide VIP displayed protective immunoregulatory effects on retinal endothelial cells cultured under high glucose conditions. This effect was carried out, in part through the VPAC2 receptor.

Next, we studied the β-adrenergic receptor agonist, Compound 49b, and its effect on the pro-resolving RvD1 pathway. Compound 49b was previously shown to suppress both inflammatory and apoptotic responses in DR. We demonstrated that Compound 49b rescued the high glucose-induced decrese in RvD1 and ...

Cataract Blindness: Socioeconomic Factors Associated With Treatment Barriers And High Blindness Rates For Women In Rural Regions Of Andhra Pradesh, Kiranpreet Kaur

Auctus: The Journal of Undergraduate Research and Creative Scholarship

Despite efforts of Vision 2020 in India, the 2001 Andhra Pradesh Eye Disease Study (APEDS) extrapolated that approximately 18.7 million blind people resided in India and projected an increase to 31.6 million blind people by 2020. Within the Andhra Pradesh state itself, the preventable blindness population had increased from approximately 1,143,150 people in 1990 to 1,402,264 people in 2001, against reformation attempts by the National Program for Control of Blindness. Of this, cataracts were consistently the leading cause of avoidable blindness. Numerous public health studies have been conducted to outline factors that preclude treatment ...
