The Benefits Of Medical Tetrahydrocannabinol On Glaucoma, Hunter Kane

Theses, Dissertations and Capstones

Introduction: This paper explores the potential therapeutic benefits of medical Tetrahydrocannabinol (THC) on glaucoma management, particularly in terms of intraocular pressure (IOP) reduction, ocular blood flow, and symptom management. Glaucoma, characterized by increased IOP and progressive optic nerve damage, is a leading cause of irreversible blindness. Current treatments focus on IOP control but may have inadequate efficacy or intolerable side effects, necessitating alternative approaches such as medical THC.

Methods: The study hypothesis posited that medical THC could significantly reduce IOP, enhance ocular blood flow, and improve symptom management in glaucoma patients. To test this hypothesis, a literature review supplemented by …

The rabbits’ eyes were divided randomly into three treatment groups: (i) treated with the antibody, (ii) treated with mitomycin C, and (iii) treated with the antibody and mitomycin C. Following surgeries, the intraocular pressure and bleb appearance were evaluated in vivo. The rabbits were sacrificed 8 weeks after the surgery, and their eyes were …

Development And Implementation Of Telemetry Devices To Identify And Characterize Sources Of Intraocular Pressure Variability In Rats, Christina M. Nicou

USF Tampa Graduate Theses and Dissertations

Eye health depends partially on intraocular pressure (IOP) as abnormal levels can lead to ocular tissue damage. Glaucoma is a neurodegenerative disease that affects nearly 80 million people worldwide [1]. It is associated with elevated IOP, which can lead to irreversible blindness. Relatively little is known about IOP dynamics and the physiological factors that affect it as IOP is typically monitored using tonometry. Tonometry is a common tool used by clinicians and researchers to measure IOP noninvasively. It provides a good estimate of IOP mean but not variance because data collection takes time. Readings can also be influenced by subject …

Wills Eye Hospital Papers

Introduction: Laser trabeculoplasty is an effective and widely used treatment for glaucoma. A new laser technology, the Eagle direct selective laser trabeculoplasty (DSLT) device, may provide automated, fast, simple, safe and effective laser treatment for glaucoma in a broader range of clinical settings. This trial aims to test the hypothesis that translimbal DSLT is effective and not inferior to selective laser trabeculoplasty (SLT) in reducing intraocular pressure (IOP) in open angle glaucoma (OAG).

Methods and analysis: This is a multicentre, randomised, controlled, investigator-masked study. The primary efficacy outcome is intergroup difference in mean change from baseline IOP measured at 6 …

Wills Eye Hospital Papers

Myopia has been discussed as a risk factor for glaucoma. In this study, we characterized the relationship between ametropia and patterns of visual field (VF) loss in glaucoma. Reliable automated VFs (SITA Standard 24-2) of 120,019 eyes from 70,495 patients were selected from five academic institutions. The pattern deviation (PD) at each VF location was modeled by linear regression with ametropia (defined as spherical equivalent (SE) starting from extreme high myopia), mean deviation (MD), and their interaction (SE × MD) as regressors. Myopia was associated with decreased PD at the paracentral and temporal VF locations, whereas hyperopia was associated with …

Hegarty, Tingting Zhan, Jonathan S Myers, L Jay Katz, Julia A Haller, Michael Waisbourd, Christine Burns, Meskerem Divers, Jeanne Molineaux, Jeffrey Henderer, Charles Brodowski, Lisa A Hark

Department of Pharmacology and Experimental Therapeutics Faculty Papers

INTRODUCTION: Appointment nonadherence is common among people with glaucoma, making it difficult for eye care providers to monitor glaucoma progression. Our objective was to determine whether the use of patient navigators, in conjunction with social worker support, could increase adherence to recommended follow-up eye appointments.

METHODS: A randomized, controlled trial evaluated the effectiveness of an intervention that used patient navigators and social workers to improve patient adherence to follow-up eye care compared with usual care. Participants with glaucoma and other eye diseases (N = 344) were identified at primary care clinics in community settings through telemedicine screening of imaging and …

Purpose: The burden of glaucoma disease among Hispanics is significantly higher than in their white counterparts. It remains unclear to what extent these differences are determined by genetic factors in Hispanics. We therefore examined a highly inbred family population-based cohort in Venezuela to estimate the proportion of genetic contribution of ocular traits relevant to glaucoma disease.

Methods: A subset of 67 participants ≥40y from the Maracaibo Aging Study (MAS) with family pedigree were randomly included. The papillary retinal nerve fiber layer (RNFL) and macular thickness were measured with Spectralis Domain-OCT. Heritability analyses (h², expressed as %) …

Leveraging Aqueous Humor Dynamics And Ocular Biometrics For Improving Therapeutic Outcomes In Glaucoma, Vikas Gulati

Theses & Dissertations

Glaucoma laser and incisional surgical treatments are associated with a known risk of complications. The ability to better predict treatment outcomes and individualize treatment recommendations can enhance the benefit to risk ratio of a treatment option. The work presented in this dissertation explores the interplay of biometrics, race and aqueous humor dynamics and their influence on treatment outcomes. In the first chapter, we demonstrate that pre-operative aqueous humor dynamics (higher aqueous flow, lower outflow facility and lower uveoscleral outflow) are predictive of greater intraocular pressure lowering after selective laser trabeculoplasty. The second chapter describes significant race-based differences in aqueous humor …

Medical Student Research Symposium

Purpose: To determine the long-term success rate of bleb needling in a predominantly African American population and to identify factors associated with success.

Methods: We conducted a retrospective, observational clinical study in patients with primary open angle glaucoma. Patients who underwent a primary trabeculectomy, with or without an express shunt placement, and then subsequently had a bleb needling procedure were selected for this study. Patients were followed every three months for a period of two years. Failure criteria included achieving an intraocular pressure (IOP) of greater than 20 mmHg or greater than 80% of the pre-needling value on …

Ahmed Vs Baerveldt Glaucoma Drainage Device In Uveitic Glaucoma, Zoe Mcwatters, Sapna Sinha, Md, Allen Ganjei, Marlene Moster, Md, Michael Pro, Md, Elizabeth Dale, Md, Daniel Lee, Md, Jonathan S. Myers, Md, L. J. Katz, Md, Scott Fudemberg, Md, Anand Mantravadi, Md, Natasha Kolomeyer, Md, Reza Razeghniejad, Md

Phase 1

Introduction: Uveitis is an inflammatory eye disorder which may elevate intraocular pressure (IOP), causing sight-threatening glaucoma. Treatment of refractory uveitic glaucoma involves implantation of a glaucoma drainage device (GDD). Uveitic glaucoma has been a minority diagnosis in prior studies comparing the valved Ahmed GDD and non-valved Baerveldt GDD. Here we compare the safety and efficacy of the Ahmed and Baerveldt GDD in uveitic glaucoma.

Methods: This retrospective comparative study was conducted on patients with uveitic glaucoma (≥14 years old) who underwent Ahmed or Baerveldt GDD implantation between 2006–2018 with a minimum follow-up of 3 months. Success was defined as …

The Efficacy And Safety Profile Of Netarsudil 0.02% In Glaucoma Treatment: Real-World Outcomes, Eric Shiuey, Ms, Melih Ustaoglu, Md, Carina Sanvicente, Md, Reza Razeghinejad, Md, L. Jay Katz, Md, Jonathan Myers, Md, Daniel Lee, Md

Phase 1

Introduction: More effective glaucoma medications are necessary as medication intolerance and non-adherence remain problematic. Netarsudil is a newly FDA-approved Rho kinase inhibitor. We hypothesize that netarsudil will safely reduce intraocular pressure (IOP) compared to baseline even while other glaucoma medications are used.

Methods: This retrospective observational study was conducted on glaucoma patients seen at the Wills Eye Hospital Glaucoma Service who received netarsudil 0.02% between March and September of 2018. Intraocular pressure (IOP, via Goldmann applanation tonometry) and best corrected visual acuity (BCVA, via Snellen visual acuity charts) comparisons between baseline and 1- and 3-month follow-up visits were performed …

Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad

Williams Honors College, Honors Research Projects

Glaucoma is a common cause of vision loss worldwide and has a large scope of symptoms, ranging from pupillary reflex defects to sleep disorders. These issues can be explained partially by a recently found subtype of retinal ganglion cells that express melanopsin, denoted melanopsin-expressing retinal ganglion cells or mRGCs for short. These cells function primarily as photoreceptors in the non-image forming pathway, but can receive input from rods and cones. Since mRGCs play a role in the pupillary reflex and regulation of the sleep-wake cycle, I investigated if glaucoma leads to the degeneration of these cells in a mouse model …

The Proliferation Of Porcine Retinal Ganglion Cells Using Pnu 282987, Rebecca Karl, David Linn

Honors Projects

The retinal ganglion cells (RGCs) from porcine eyes were extracted to work towards a potential therapy for glaucoma. There is not a known cause of glaucoma or the apoptosis of RGCs that cause the eventual blindness associated with glaucoma. The goal of this protocol is to protect the RGCs from dying by adding a nicotinic acetylcholine receptor activator to induce neuronal proliferation and protect against glutamate-induced excitotoxicity. PNU 282987 was used as the nicotinic acetylcholine receptor activator due to its neuroprotective properties. We hypothesized that we would observe the proliferation of RGCs (associated with increased cell numbers) with varying levels …

Microtubule Imaging Reveals Cytoskeletal Deficit Predisposing The Retinal Ganglion Cell Axons To Atrophy In Dba/2j, Denis Sharoukhov, Festa Bucinca-Cupallari, Hyungsik Lim

Publications and Research

PURPOSE: Glaucoma is characterized by progressive loss of the retinal ganglion cells (RGCs) and their axons. Here we test an outstanding notion that microtubules (MTs) within RGC axons degrade before the loss of morphology (‘‘MT hypothesis’’).

METHODS: The integrity of axonal MTs was interrogated by intrinsic second-harmonic generation (SHG) microscopy. Using DBA/2J mice as a model of glaucoma and DBA/2J-Gpnmbþ as a nonglaucomatous control, the relationship between MT disruption and morphology was quantitatively examined as a function of age and sex in the fresh retinal wholemounts.

RESULTS: The mean SHG density (i.e., the mean SHG intensity per thickness) was significantly …

Predicting Important Patient-Reported Outcomes For Glaucoma Management: Cross-Sectional Study, Lavanya Uruthiramoorthy

Electronic Thesis and Dissertation Repository

The initiative to understand patient-reported outcomes (PROs) has increased to improve glaucoma management. We sought to identify important predictors of four PROs: social support and community integration, presence of depressive symptoms, vision-related quality of life (VRQoL) and preference-based Health-Related quality of life (HRQoL). A cross-sectional study was conducted among patients in London, Ontario (n=250). Regression models, and classification and regression trees were built. Leave-one-out cross-validation assessed the models’ predictive performance. Mobility aid use, best corrected visual acuity (BCVA), income and living arrangements were predictors identified for VRQoL, and social support and community integration. Mobility aid use was also predictive of …

Background: The purpose of this study is to evaluate the number of eyedrops available per bottle of a variety of commonly prescribed glaucoma medications.

Methods: Six bottles of each glaucoma medication were tested: three each in the vertical and horizontal orientations. Bottles were housed in a customized force gauge apparatus designed to mimic ballpoint fingertip contact with a bottle. At a standard rate, all drops were expressed from each bottle and counted with an automated drop counter. Simultaneously, bottle volume was measured and drop size and number were also estimated. The main outcome measures were: total number of drops, volume …

Loss Of Displaced Starburst Amacrine Cells In A Rat Glaucoma Model, C A. Cooley-Themm, Q Ameel, David M. Linn, Cindy L. Linn

Peer Reviewed Articles

Acetylcholine (ACh) release by starburst amacrine cells (SACs) has been implicated in the production of retinal waves during early retinal development. Inhibitory gamma-aminobutyric acid (GABA) release by SACs is known to be involved in directional selectivity in the mature retina. However, the role of SAC release of ACh in the adult developed mammalian retina is not entirely understood. Some evidence suggests a neuroprotective effect on retinal ganglion cells (RGCs) acting through alpha7 nicotinic acetylcholine receptors (nAChRs) present in RGCs. If ACh released by SACs is neuroprotective to RGCs, it would follow that this cholinergic transmission might be compromised in glaucoma …

Cost-Effectiveness Of Selective Laser Trabeculoplasty (Slt) Versus Argon Laser Trabeculoplasty (Alt) In Uncontrolled Open Angle Glaucoma Patients Having At Least One Full Previous Slt: An Economic Evaluation Alongside An Ongoing Randomized Controlled Clinical Trial, Muhammad Rakibuz-Zaman

Electronic Thesis and Dissertation Repository

Background and objective: ALT and SLT are both safe and effective for glaucoma treatment. We performed a cost-effectiveness analysis (CEA) of SLT versus ALT for a six-month follow-up period in uncontrolled open angle glaucoma patients having at least one full previous SLT from an ongoing RCT. Methods: Trial based treatment costing and IOP reduction at 6-month follow-up from baseline for both intervention arms were calculated. A decision tree model was developed considering possible clinical pathways of patients undergoing repeat laser trabeculoplasty. CEA among ALT and SLT was done, and ICERs were calculated from both societal and ministry perspective. One way …

Regulation Of Phosphatase And Tensin Homolog Expression And Activity By Transforming Growth-Factor Beta In The Trabecular Meshwork Cells: Implications For Primary Open Angle Glaucoma, Nikoleta Tellios

Electronic Thesis and Dissertation Repository

Glaucoma is a multifactorial condition caused, in part, by fibrosis of the sieve-like trabecular meshwork (TM) tissue, which impedes drainage of aqueous humor (AH), leading to increased intraocular pressure and associated optic nerve damage and blindness. Fibrosis of the TM is mainly caused by the increased levels of active transforming growth factor-β 2 (TGFβ2) in the AH of glaucoma patients.

Previous reports have shown that TGFβ decreases the expression of Phosphatase and Tensin Homolog (PTEN) gene and that PTEN is a major regulator of ECM deposition. In this study we investigate the regulation of PTEN protein expression and …

Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert

USF Tampa Graduate Theses and Dissertations

Glaucoma is a neurodegenerative protein misfolding disorder classified by increases in IOP, damage to retinal ganglion cells (RGCs), optic nerve (ON) head damage, and progressive irreversible blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma, constituting over 90% of clinical cases. POAG is observed in patients where normal outflow channels, mainly the trabecular meshwork (TM), are exposed at the angle formed by the iris and cornea. However, due to TM cellular dysfunction, aqueous outflow resistance is increased preventing normal circulation of aqueous humor. Recent studies have shown that in 2-4% of POAG cases, increased intracellular levels of …

Prevention Of Glaucoma-Induced Retinal Ganglion Cell Loss Using Alpha7 Nachr Agonists, P J. Birkholz, C A. Gossman, M K. Webster, David M. Linn, Cindy L. Linn

Peer Reviewed Articles

In this study, the neuroprotective effect of various nicotinic alpha7 acetylcholine receptor agonists in an in-vivo model of glaucoma using adult Long Evans rats was analyzed. Glaucoma-like conditions were induced in the eyes of Long Evans rats after injection of hypertonic saline into episcleral veins to create scar tissue and increase the animal’s intraocular pressure. This procedure produced significant loss of retinal ganglion cells within one month and was associated with an increase of intraocular pressure. Using this model system, various alpha7 nicotinic acetylcholine receptor (a7 nAChR) agonists were applied at different doses as eye drops to the right eye …

Bioengineering In Vitro Human Trabecular Meshwork Models For Glaucoma Therapeutic Screening, Karen Yud Torrejon

Legacy Theses & Dissertations (2009 - 2024)

Glaucoma refers to a group of slowly progressing eye disorders that lead to damage to the optic nerve, resulting in irreversible vision loss. Recent statistics by the World Health Organization places glaucoma as a leading cause of blindness worldwide, affecting nearly 80 million people. Lowering intraocular pressure (IOP) is currently the only effective target for therapeutic intervention in glaucoma. IOP is mostly controlled by the outflow of the aqueous humor (AH) through the trabecular meshwork (TM). The TM and adjacent endothelium of Schlemm’s canal, known as the conventional outflow-tract, control AH outflow and thus determine IOP.

A Comparison Of Clinical Trial And Model-Based Cost Estimates In Glaucoma – The Case Of Repeat Laser Trabeculoplasty In Ontario, Omar Akhtar

Electronic Thesis and Dissertation Repository

Background and objective: For cost-effectiveness analyses (CEA) of glaucoma interventions to be of use they require valid and accurate cost and effectiveness data. Costs remain understudied relative to effectiveness. The impact of cost estimation methods on resultant estimates is unknown in glaucoma. Direct measurement of costs is labour-intensive and expensive. Decision-analytic modelling of costs using literature sources, expert opinion, institutional experience and assumptions provides a quicker, less laborious alternative to empirical costing. A lack of long-term effectiveness data in chronic diseases like glaucoma means that modelling is widespread and inevitable, both for CEAs and budget impact projections. The same problem …

Resolution Of Bilateral Ptosis After Reduction Of Unilaterally Elevated Intraocular Pressure In A Child With Axenfeld-Reiger Spectrum Disorder., Ketki Soin, Alex V. Levin

Wills Eye Hospital Papers

We report a 9-month-old boy with bilateral pseudoptosis associated with elevated IOP. The patient had previously undergone bilateral trabeculectomies and Ahmed tube placement and right cataract extraction and penetrating keratoplasty. At presentation, the right eye IOP was 24 mm Hg and the left eye IOP was 32 mm Hg. Approximately 2 weeks after dorzolamide was added to the treatment regimen for the left eye, the mother reported that the ptosis had resolved. We suggest several explanations for the resolution of the ptosis.
