A Trained Eye: Optometrists' View Into Primary Care, Louis C. Magee III 2022 University of Mississippi

A Trained Eye: Optometrists' View Into Primary Care, Louis C. Magee Iii

Honors Theses

The aim of this thesis is to explore and present the auxiliary responsibilities of doctors of optometry, particularly those involved with primary health care such as screening for serious diseases. This idea was approached by researching the technological capabilities of optometrists, the diseases and conditions they commonly detect, as well as the barriers preventing some people from receiving proper eye care. The importance of optometrists as primary care providers is steadily rising alongside their capabilities. There are many instances within a routine eye exam in which an optometrist is able to detect and recommend treatment of a serious disease. Also ...

Case Report: Bartonella Quintana-Associated Neuroretinitis, Kelly Seidler OD, Kelly A. Malloy OD 2022 Salus University

Case Report: Bartonella Quintana-Associated Neuroretinitis, Kelly Seidler Od, Kelly A. Malloy Od

Optometric Clinical Practice

Background: Neuroretinitis is a self-limiting condition which typically causes monocular vision loss with good potential for visual recovery. It may be idiopathic or associated with infectious or inflammatory conditions which can carry systemic implications. Neuroretinitis classically presents with disc edema followed by development of a macular star pattern of exudates. It is most commonly attributed to Cat Scratch Disease, or Bartonella henselae infection. However, there have been few published reports of Bartonella quintana associated neuroretinitis.

Case Report: A 60-year-old patient presented with unilateral vision loss preceded by flu-like illness. The patient had exposure to a recently adopted cat. Fundus examination ...

Bilateral, Full-Thickness Macular Holes While Undergoing Chemotherapy, Sarah Dieter Od, Brett Garee Od Ms, Susan Zacatelco Od, Julie Henry Od

Optometric Clinical Practice

Background: Bilateral, full-thickness macular holes are a rare condition that can substantially affect quality of life. Macular hole diagnosis and treatment is key for these patients.

Case Report: A 71 year old Caucasian male presented with a chief complaint of distance blur in both eyes, worsening over the past 1-2 weeks. He had no diagnosis of diabetes. He added that his prostate cancer had spread and that his last treatment ended 9 days ago. He was ultimately diagnosed with bilateral, full-thickness macular holes. Referral to a retinal specialist for surgical management yielded good results.

Conclusion: This is the first case ...


Cefuroxime-Induced Toxic Maculopathy: A Cataract Co-Management Conundrum, Leonid Skorin Jr., DO, OD, MS 2022 Mayo Clinic Health System

Cefuroxime-Induced Toxic Maculopathy: A Cataract Co-Management Conundrum, Leonid Skorin Jr., Do, Od, Ms

Optometric Clinical Practice

Background: Cefuroxime-induced toxic maculopathy can occur when an incorrect dilution is injected intracamerally after cataract surgery. This results in a guarded visual prognosis. Cefuroxime-induced toxic maculopathy can also occur sporadically even when the medication dilution is the standard correct dosage. These patients usually recover their vision by the first postoperative week.

Case Report: A 72-year-old Caucasian female developed cefuroxime-induced toxic maculopathy after uneventful cataract surgery. Investigation of the case confirmed that she had a sporadic response to the cefuroxime. It was verified that she received the standard correct dilution of cefuroxime intracamerally. The patient showed a significant improvement in her ...

Isolated Optic Neuropathy As The Presenting Sign Of Neurosyphilis, Kasey Zann Od, Molly Johnson Od, James Fabian Od

Optometric Clinical Practice

Background: Detection and treatment of syphilitic ocular disease without a known history of syphilis is often difficult due to its varied presentations. Early diagnosis and treatment are the key to reducing risk of permanent vision loss, particularly with optic nerve and retinal manifestations.

Case Report: This case report describes a 44 year-old male who was diagnosed with neurosyphilis through his work-up for unilateral optic neuropathy.

Conclusion: This report illustrates the importance of including syphilis lab testing in the setting of optic nerve edema. Syphilis should be considered in any inflammatory ocular disease, especially in patients with atypical presentations and high-risk ...


Medication-Induced Oculomotor Dysfunction: A Report Of Two Cases, Eric Lee OD 2022 Memphis VA

Medication-Induced Oculomotor Dysfunction: A Report Of Two Cases, Eric Lee Od

Optometric Clinical Practice

Background: Consideration of current medications and their interactions as a source of new onset oculomotor dysfunction is imperative for providing good eye care. Medication etiology should be particularly suspected when the symptoms begin with the initiation of a new medication and resolved with discontinuation of the same medication.

Case Reports: Presented are two cases demonstrating that it is prudent to be aware of medications capable of inducing oculomotor dysfunction. Each case reveals instances of acute oculomotor dysfunction after the initiation of a central nervous system affecting medication. Case 1 details a partial pupil sparing third nerve palsy after initiating the ...


Longstanding Crystalline Retinopathy Secondary To Intravitreal Triamcinolone Injection, Katherine Thomas OD, Jeffery Curry OD 2022 Lake City VAMC

Longstanding Crystalline Retinopathy Secondary To Intravitreal Triamcinolone Injection, Katherine Thomas Od, Jeffery Curry Od

Optometric Clinical Practice

Background: Crystalline retinopathy has many disparate etiologies with varying potentials in visual outcome. Due to the potential severity of these outcomes, differentiation of etiology is critical to guide both follow up and treatment regimen. Diagnosis can be facilitated with a thorough medical history, clinical presentation, and imaging such as optical coherence tomography (OCT).

Case Report: This case demonstrates a rare incidence of crystalline retinopathy in a 65-year-old male attributed to a single intravitreal triamcinolone acetonide (IVTA) injection with 8 year follow up data, followed by a review of other types of crystalline retinopathy secondary to pharmaceutical agents.

Conclusion: A complete ...

Progressive Lenses And Acute Anisomentropia, Alena Lane 2022 Technological University Dublin

Progressive Lenses And Acute Anisomentropia, Alena Lane

Conference Papers

The aim of the poster is to demonstrate that presbyopic patients with acute anisometropia can continue using progressive lenses. Acute or induced anisometropia occurs when a sudden change in the prescription is introduced. A typical example of this occurs following the cataract operation to one eye. The problem arises when the difference in refractive power of both eyes after the operation is 2.00D and more. The difference in lens power can cause the eyes to see different size images and lead to difficulties in fusing them. Additionally, when an image is viewed off axis through the spectacle lens away ...

Surgical Training In Ophthalmology: Role Of Eyesi In The Era Of Simulation-Based Learning, Sehrish Nizar Ali Momin, Abdul Sami Memon, Muhammad Bilal Malik, Pir Salim Mahar 2022 Aga Khan University

Surgical Training In Ophthalmology: Role Of Eyesi In The Era Of Simulation-Based Learning, Sehrish Nizar Ali Momin, Abdul Sami Memon, Muhammad Bilal Malik, Pir Salim Mahar

Section of Ophthalmology

Recent advancements in surgical training methods have escalated the need for simulators. The EyeSi simulation has played a major role in Ophthalmology training by providing opportunity to the novice residents to grasp the surgical steps of the procedure and master the skill by repeated attempts. Participants were assessed on single level of cataract module and their consecutive scores were assessed with each attempt. It was found that repetitive practice on simulator can help develop proficiency in the desired steps that can ultimately prepare the surgical trainees for real life surgery.

Diagnosis Of Polypoidal Choroidal Vasculopathy From Fluorescein Angiography Using Deep Learning, Yu-Yeh Tsai, Wei-Yang Lin, Shih-Jen Chen, Paisan Ruamviboonsuk, Cheng-Ho King, Chia-Ling Tsai

Publications and Research

Purpose: To differentiate polypoidal choroidal vasculopathy (PCV) from choroidal neovascularization (CNV) and to determine the extent of PCV from fluorescein angiography (FA) using attention-based deep learning networks.

Methods: We build two deep learning networks for diagnosis of PCV using FA, one for detection and one for segmentation. Attention-gated convolutional neural network (AG-CNN) differentiates PCV from other types of wet age-related macular degeneration. Gradient-weighted class activation map (Grad-CAM) is generated to highlight important regions in the image for making the prediction, which offers explainability of the network. Attention-gated recurrent neural network (AG-PCVNet) for spatiotemporal prediction is applied for segmentation of PCV ...
