The Benefits Of Medical Tetrahydrocannabinol On Glaucoma, Hunter Kane
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 …

Bilateral Acute Ocular Ischemic Syndrome Following Head And Neck Radiation, Dipali Nemade, Paul Ferguson, Vikram Shivkumar, Dennis Cole

Previous literature has established a clear correlation between radiation therapy (RT) to the head and neck leading to aggressive atherosclerosis of the carotid arteries and subsequent increased risk for ischemic stroke. Stenosis of carotid arteries can lead to Ocular Ischemic syndrome (OIS). We present a case of acute bilateral OIS following head and neck RT for left tonsillar squamous cell carcinoma (SCC) in a 64 year-old Caucasian male. Routine large vessel cerebrovascular screening following head and neck radiotherapy should be considered as a means of potentially mitigating future stroke risk through initiation of medical therapy and interventional modalities as a …

Ophthalmology
We report a rare case of association of temporal arteritis with recurrent central corneal ulcer. A 91-year-old male with a remote history of clinically diagnosed giant cell arteritis (GCA) and penetrating keratoplasty (PK) for corneal edema in 1990’s in the left eye presented with irritation and severe dry eye. He progressively developed central corneal ulcer regardless of treatment with aggressive lubrication and patching. The clinical course, blood tests and temporal artery biopsy results yielded the diagnosis of recurrent GCA. The clinical course improved after starting oral steroids. The case report illustrates the importance of ruling out GCA in patients with …

We read the article by Miguel et al1 regarding Purtscher’s and Purtscher-like retinopathies with great interest. As the authors well describe, ‘Purtscher-like retinopathy’ is diagnosed in patients with fundus findings similar to Purtscher’s retinopathy, without a history of trauma but with known systemic associations.1 Current proposed mechanisms for the underlying pathogenesis include leukocyte aggregation by activated complement factor 5 (C5a).2 As noted by the authors’ systematic review, there is currently no established treatment for Purtscher-like retinopathy, although the literature consists of several case reports of treatment with corticosteroids, without certainty as to effect on the clinical course.1 Herein, …
Cost-Savings Analysis Of Telemedicine Use For Ophthalmic Screening In A Rural Appalachian Health Clinic, D. Russell Richardson, Russell Fry Ii, Michael Krasnow Do, Phd
Cost-Savings Analysis Of Telemedicine Use For Ophthalmic Screening In A Rural Appalachian Health Clinic, D. Russell Richardson, Russell Fry Ii, Michael Krasnow Do, Phd
Ophthalmology
Life in mountainous, rural areas poses unique obstacles for ophthalmic care--notably, a lack of access to ophthalmologists and cost of care. Using telemedicine as a screening tool addresses both issues for diabetic retinopathy (DR) screening, as fundus photography has been determined to be sensitive and specific when screening for DR.1,2 The American Diabetes Association places a Grade E recommendation on fundus photography as a screening tool.3 We analyze the financial impact of ophthalmic telemedicine in a mountainous, rural health clinic in West Virginia over a seven year period from 2003-2009. At-risk patients are screened with a fundus camera …
Colocalization Of Increased Transforming Growth Factor-Β-Induced Protein (Tgfbip) And Clusterin In Fuchs Endothelial Corneal Dystrophy, Ula V. Jurkunas, Maya Bitar, Ian Rawe
Colocalization Of Increased Transforming Growth Factor-Β-Induced Protein (Tgfbip) And Clusterin In Fuchs Endothelial Corneal Dystrophy, Ula V. Jurkunas, Maya Bitar, Ian Rawe
Ophthalmology
PURPOSE: To investigate the differential expression of TGFBIp in normal human and Fuchs endothelial corneal dystrophy (FECD) endothelial cell-Descemet’s membrane (HCEC-DM) complex, and to asses the structural role of TGFBIp and clusterin (CLU) in guttae formation.
METHODS: HCEC-DM complex was dissected from stroma in normal and FECD samples. Proteins were separated by 2-D gel electrophoresis and subjected to proteomic analysis. N-terminal processing of TGFBIp was detected by Western blot analysis with two separate antibodies against the N- and C-terminal regions of TGFBIp. Expression of TGFBI mRNA was compared by using real-time PCR. Subcellular localization of TGFBIp and CLU in corneal …

Purpose: To compare the relative expression of peroxiredoxin (Prx) proteins in normal human corneal endothelium with endothelium in corneas affected by Fuchs’ endothelial dystrophy (FED) and between normal human endothelium and epithelial/stromal tissue.
Methods: Human corneal endothelial cell-Descemet’s membrane (HCEC-DM) complexes from normal and FED corneal buttons were dissected from the epithelium/stroma. For proteomic analysis, HCEC-DM protein extracts were separated by using two-dimensional gel electrophoresis. Relative differences in protein spot density was analyzed. Proteins of interest, including Prx isoforms, were identified by MALDI-TOF (matrix-assisted desorption ionization-time of flight) mass spectrometry. Western blot analysis compared the relative expression of Prx isoforms …
