Evaluation Of Multi-Level Barriers And Facilitators In A Large Diabetic Retinopathy Screening Program In Federally Qualified Health Centers: A Qualitative Study, Ana Bastos De Carvalho, S. Lee Ware, Tamara Belcher, Franceska Mehmeti, Eric B. Higgins, Robert Sprang, Cody Williams, Jamie L. Studts, Christina R. Studts
Ophthalmology and Visual Science Faculty Publications
BACKGROUND: Recommended annual diabetic retinopathy (DR) screening for people with diabetes has low rates in the USA, especially in underserved populations. Telemedicine DR screening (TDRS) in primary care clinics could expand access and increase adherence. Despite this potential, studies have observed high variability in TDRS rates among clinics and over time, highlighting the need for implementation supports. Previous studies of determinants of TDRS focus on patients' perspectives, with few studies targeting upstream multi-level barriers and facilitators. Addressing this gap, this qualitative study aimed to identify and evaluate multi-level perceived determinants of TDRS in Federally Qualified Health Centers (FQHCs), to inform ...

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 then ...
Critique Of Experimental Procedures Targeting Retinitis Pigmentosa, 2021 University of Maine - Main
Critique Of Experimental Procedures Targeting Retinitis Pigmentosa, Jenna Goss
Retinitis Pigmentosa (RP) is a group of hereditary genetic disorders, all causing degradation of the retina through loss of rod photoreceptor cells, ultimately causing loss of vision and in many cases complete blindness. Despite the prevalence o fRetinitis Pigmentosa disorders, safe and effective treatment methods have not yet been approved to stop or regain vision loss in patients diagnosed with RP. However, the ophthalmic field as a whole is working on several new technologies and procedures in order to both slow loss of vision as well as potentially regain lost sight. In this thesis, I describe the genetic causes and ...

This study characterizes differences in glaucomatous eyes with and without high axial myopia using custom automated analysis of OCT images. 452 eyes of 277 glaucoma patients were stratified into non (n = 145 eyes), mild (n = 214 eyes), and high axial myopia (axial length (AL) > 26 mm, n = 93 eyes). Optic disc ovality index, tilt and rotation angle of Bruch´s membrane opening (BMO) and peripapillary choroidal thickness (PCT) were calculated using automated and deep learning strategies. High myopic optic discs were more oval and had larger BMO tilt than mild and non-myopic discs (both p < 0.001). Mean PCT was thinnest in high myopic eyes followed by mild and non-myopic eyes (p < 0.001). BMO rotation angle, global retinal nerve fiber layer (RNFL) thickness and BMO-minimum rim width (MRW) were similar among groups. Temporal RNFL was thicker and supranasal BMO-MRW was thinner in high myopic eyes. BMO tilt and PCT showed moderate and temporal RNFL and nasal BMO-MRW showed weak but significant associations with AL in multivariable analyses (all p < 0.05). Large BMO tilt angle and thin PCT are characteristics of highly myopic discs and were not associated with severity of glaucoma. Caution should be exercised when using sectoral BMO-MRW and RNFL thickness for glaucoma management decisions in myopic eyes.

Narrative Medicine In Ophthalmology, Martina Rama
While technological and medical advancements have made it possible to diagnose and treat previously deadly conditions, modern day medicine comes with a new set of challenges around the doctor-patient relationship. Scientifically competent medicine cannot always help patients cope emotionally with their health issues. For physicians, understanding patients’ experience with illness in order to comfort and accompany them through their challenges is just as important as meeting their physical health needs. Dr. Rita Charon, the founder of narrative medicine, highlights how physicians today sometimes lack the ability to connect with, empathize with, and support their patients through difficult diagnoses.1 When ...

Tissues typically harbor subpopulations of resident immune cells that function as rapid responders to injury and whose activation leads to induction of an adaptive immune response, playing important roles in repair and protection. Since the lens is an avascular tissue, it was presumed that it was absent of resident immune cells. Our studies now show that resident immune cells are a shared feature of the human, mouse, and chicken lens epithelium. These resident immune cells function as immediate responders to injury and rapidly populate the wound edge following mock cataract surgery to function as leader cells. Many of these resident ...
Properties Of Multivesicular Release From Mouse Rod Photoreceptors Support Transmission Of Single-Photon Responses, 2021 University of Nebraska Medical Center
Properties Of Multivesicular Release From Mouse Rod Photoreceptors Support Transmission Of Single-Photon Responses, Cassandra L. Hays, Asia L. Sladek, Greg D. Field, Wallace B. Thoreson
Journal Articles: Ophthalmology
Vision under starlight requires rod photoreceptors to transduce and transmit single-photon responses to the visual system. Small single-photon voltage changes must therefore cause detectable reductions in glutamate release. We found that rods achieve this by employing mechanisms that enhance release regularity and its sensitivity to small voltage changes. At the resting membrane potential in darkness, mouse rods exhibit coordinated and regularly timed multivesicular release events, each consisting of ~17 vesicles and occurring two to three times more regularly than predicted by Poisson statistics. Hyperpolarizing rods to mimic the voltage change produced by a single photon abruptly reduced the probability of ...

This case series describes acute corneal hydrops in three young horses. Due to similarities in the clinical appearance and progression of the disease with that which is reported in humans and cats with acute corneal hydrops, traumatic Descemet’s membrane rupture was suspected to be the underlying aetiology in these equine cases. The horses presented with acute severe corneal oedema with intrastromal bullae formation and anterior bulging of the corneal contour. Focal posterior corneal changes were also seen in two of three cases. Mild anterior uveitis was also present. Other causes of corneal oedema (e.g. glaucoma) were ruled out ...
