Rare Jugular Bulb Tumor Presenting As Bilateral Papilledema, Yoona Choe, Matthew Boyle, Peter Maduka

Rowan-Virtua Research Day

Optic disc edema, which may arise from a range of inflammatory, ischemic, compressive, infiltrative, or hereditary causes, can also indicate elevated intracranial pressure in the form of papilledema. Given its potential association with life-threatening conditions such as mass lesions or venous sinus thrombosis, timely identification and thorough evaluation are critical. In this case, a 61-year-old female presented with a complaint of a new-onset floater in her left eye. Despite minimal symptoms and an unremarkable systemic review, dilated fundus examination revealed bilateral optic disc edema with hyperemia and hemorrhages, prompting urgent neuroimaging. MRI and MRV identified venous thrombi in the right …

Thymosin Beta-4: A Novel Treatment For Acanthamoeba Keratitis, Victoria A. Murphey

All Theses

Acanthamoeba keratitis (AK) is a severe corneal infection caused by the free-living amoeba, Acanthamoeba. Both stages of its life cycle (trophozoite and cyst) cause infection, primarily in contact lens wearers. It is often misdiagnosed, leading to delayed treatment and poor clinical outcomes. Current treatment options for AK rely on anti-amoebic agents that are toxic to corneal epithelial cells. Further, no single drug can eliminate both forms of the amoeba. Approximately 30% of all AK infections require a corneal transplant.

Thymosin beta-4 (Tβ4) is a G-actin binding protein synthesized in almost all human cells, including corneal epithelial cells. Tβ4 exhibits …

Normative Variability In Retinal Nerve Fiber Layer Thickness: Does It Matter Where The Peaks Are?, Sowjanya Gowrisankaran, Ashkan Abbasi, Xubo Song, Joel Schuman, Gadi Wollstein, Bhavna Antony, Hiroshi Ishikawa

Wills Eye Hospital Papers

PURPOSE: Retinal nerve fiber layer thickness (RNFLT), a glaucoma biomarker, has a wide normative range affecting its sensitivity and specificity for abnormality detection. The interindividual RNFLT peak location variability contribution to this wide normative range has not been directly evaluated. The purpose of this study is to assess the effect of RNFLT peak normalization (PN) on normative variability.

METHODS: Circumpapillary RNFLT profiles at 1.7 mm radius from the optic nerve head (ONH) were re-sampled from optical coherence tomography (OCT) volumes (Cirrus HD-OCT, 200 × 200) obtained from one eye of 83 healthy individuals. Fovea-ONH axis (FOA) was calculated from corresponding …

Advancing Research On Retinitis Pigmentosa: An Investigation Of Natural History, Visual System Plasticity, And Mutation-Independent Treatment., Cecilia A. Attaway

Electronic Theses and Dissertations

Retinitis Pigmentosa (RP) is an inherited retinal disease characterized by rod and then cone photoreceptor degeneration. ~25% of cases are caused by a genetic mutation that results in autosomal dominant RP (adRP). There has been a lack of exploration of the progression of degeneration in adRP models. In Chapter Two, I examined visual acuity (VA) changes, retinal structure, and function from early to late-stage disease in a murine P23H Rho ‘knock-in’ mouse model (Rho^P23H/+), the most common form of adRP in North America. To establish a natural history, I evaluated behavioral VA, using the visual water task, …

Faculty, Staff and Students Publications

Over the last 20 years, research into the Meibomian glands of the eyelids has increased exponentially and is now widely recognized as a field of research. It is all the more astonishing that knowledge about another type of gland in the eyelids, the Moll glands or ciliary glands, has almost stagnated and there has been little to almost no progress, even though this type of gland as a whole takes up a relatively large volume in the upper and lower eyelids. There is not much information about the namesake Moll or the function of the glands although these are listed …

Diabetic Retinopathy: A Pathophysiological Discussion, Nathanael C. Nicholls

Senior Honors Theses

Diabetic retinopathy is a severe complication of diabetes that is capable of causing vision loss or blindness. As a result of hyperglycemia, the disease increases oxidative stress and activates biochemical processes such as the Hippo pathway and the complement system to cause significant damage to the retina. Overexpression of BTG1 and microRNA-183 enables activation of biochemical pathways that lead to negative effects on the retinal vascular endothelium including angiogenesis and inflammation. Conventional methods of diagnosis for diabetic retinopathy include fundus examination, nucleoside detection, and optical coherence tomography angiography. Photocoagulation and hormonal intravitreal injection are the most popular current treatments, while …

In cataract surgery, the opacified crystalline lens is replaced by an artificial intraocular lens (IOL), requiring precise preoperative selection of parameters to optimize postoperative visual quality. Three-dimensional customized eye models, which can be constructed using quantitative data from anterior segment optical coherence tomography, provide a robust platform for virtual surgery. These models enable simulations and predictions of the optical outcomes for specific patients and selected IOLs. A critical step in building these models is estimating the IOL's tilt and position preoperatively based on the available preoperative geometrical information (ocular parameters). In this study, we present a machine learning model that, …

Mitochondrial dysfunction fuels vascular inflammation and atherosclerosis. Mitochondrial calcium uptake 1 (MICU1) maintains mitochondrial Ca2+ homeostasis. However, the role of MICU1 in vascular inflammation and atherosclerosis remains unknown. Here, we report that endothelial MICU1 prevents vascular inflammation and atherosclerosis by maintaining mitochondrial homeostasis. We observed that vascular inflammation was aggravated in endothelial cell–specific Micu1 knockout mice (Micu1ECKO) and attenuated in endothelial cell–specific Micu1 transgenic mice (Micu1ECTg). Furthermore, hypercholesterolemic Micu1ECKO mice also showed accelerated development of atherosclerosis, while Micu1ECTg mice were protected against atherosclerosis. Mechanistically, MICU1 depletion increased mitochondrial Ca2+ influx, thereby decreasing the expression …

Ocular Surface Glycocalyx In Health And Disease, Rafael Martínez-Carrasco, Ajay Sharma

Pharmacy Faculty Articles and Research

The glycocalyx is a dynamic carbohydrate-enriched structure that forms a dense coating on the surface of animal cells, including those at the ocular surface. It plays a critical role in maintaining cellular functions and it has a significant influence in disease processes. At the ocular surface, glycoproteins such as mucins are essential for hydration, lubrication, and barrier protection. Proteoglycans and glycolipids contribute to cell signaling, and mediate interactions with pathogens. Alterations in the glycocalyx are implicated in a spectrum of ocular conditions, including dry eye disease, ocular allergies, infections, and systemic diseases such as Graft-versus-host disease (GVHD) and diabetes mellitus. …

Future Applications Of Fluorescence Lifetime Imaging Ophthalmoscopy In Neuro-Ophthalmology, Neurology, And Neurodegenerative Conditions, Daniel M. Markowitz, Elizabeth Affel, György Hajnóczky, Robert C. Sergott

Farber Institute for Neuroscience Faculty Papers

Fluorescence lifetime imaging ophthalmoscopy (FLIO) has emerged as an innovative advancement in retinal imaging, with the potential to provide in vivo non-invasive insights into the mitochondrial metabolism of the retina. Traditional retinal imaging, such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) intensity imaging, focus solely on structural changes to the retina. In contrast, FLIO provides data that may reflect retinal fluorophore activity, some of which may indicate mitochondrial metabolism. This review builds upon the existing literature to describe the principles of FLIO and established uses in retinal diseases while introducing the potential for FLIO in neurodegenerative conditions.

Ciliary Arl14b In Vision, Alexis Breann Crockett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Primary cilia are highly specialized organelles that regulate signaling, trafficking, and sensory perception across multiple tissues, including the retina. The small GTPase ADP Ribosylation Factor-Like Protein 13B (ARL13B) is an atypical ARF-family protein enriched in cilia. ARL13B acts as a guanine exchange factor (GEF) for another small GTPase ARF-like Protein 3 (ARL3). Mutations in ARL13B cause Joubert syndrome, a ciliopathy characterized by brain malformation, developmental delays, and retinal degeneration. Despite ARL13B’s known ciliary localization and clinical relevance, ARL13B’s precise functions in cilia remain poorly defined. This dissertation investigates the cilia-specific roles and GEF-specific roles of ARL13B in photoreceptors using two …

On The Nose: Nasal Neurostimulation As A Technology Countermeasure For Sinonasal Congestion In Astronauts, Timon Ax, Philipp H Zimmermann, Tomas L Bothe, Karen Barchetti, Cintia S De Paiva, Francesc March De Ribot, Slade O Jensen, Thomas J Millar

Faculty, Staff and Students Publications

Human spaceflight subjects the body to numerous and unique challenges. Astronauts frequently report a sense of sinonasal congestion upon entering microgravity for which the exact pathomechanisms are unknown. However, cephalad fluid shift seems to be its primary cause, with CO2 levels and environmental irritants playing ancillary roles. Current management focuses on pharmacotherapy comprising oral and nasal decongestants and antihistamines. These are among the most commonly used treatments in astronauts. With longer and more distant space missions on the horizon, there is a need for efficacious and payload-sparing non-pharmacological interventions. Neurostimulation is a promising countermeasure technology for many ailments on Earth. …

Intraocular Lens Power Calculation In Challenging Cases, Jack X Ma, Li Wang, Douglas D Koch

Faculty, Staff and Students Publications

In this article, we reviewed recently published papers of intraocular lens (IOL) power calculation in special eyes. In short eyes, accurate estimation of effective lens position is critical, and the ZEISS artificial intelligence IOL calculator produces the best outcomes. In long eyes, accuracy has been improved with axial length (AL) adjusted formulas such as the Wang-Koch AL adjustment and newer IOL formulas. In keratoconic eyes, hyperopic refractive outcomes increase with steeper keratometric values, and accuracy is poor in eyes with keratometric values ≥50.0 D. Two keratoconus-specific formulas (Barrett True K for keratoconus and Kane keratoconus) have been introduced. In eyes …
