Impact of Diet and Gut Microbiome on Nonhuman Primate Models of Age-Related Macular Degeneration

Ocular trauma is a leading cause of blindness in the United States. There have been studies of ocular trauma and penetrating injury, but few examining visual outcomes following gun related trauma to orbital and ocular structures. Furthermore, associations related to this type of trauma and visual outcomes has not been extensively studied.

Repeatability of Vascular Density Measurements of the Intermediate Retinal Plexus Layer using OCT Angiography

Tue, 12 Nov 2024 00:00:00 +0000

OCTA is a non-invasive technique that can image blood flow in the retina and choroid in 3 dimensions. Commercially, the instrument automatically segments the vasculature into 2 separate layers, but histologically, there are 3 different layers of blood vessels. My summer project was focused on determining the reliability and repeatability of the vascular flow density in the intermediate capillary plexus (ICP) layer using OCTA in normal eyes and eyes with cystoid macular edema (CME) and retinal vasculopathy.

Inequities in distribution of specialty ophthalmology care. Increased studies demonstrating efficacy, cost efficiency of teleophthalmology. Rising concerns of compensation, perhaps hindering adoption.

Natural History and Predictors of Vision Loss in Eyes with Diabetic Macular Edema and Good Initial Visual Acuity

Tue, 5 Nov 2024 00:00:00 +0000

Purpose: To identify clinical and anatomic factors associated vision loss in eyes with treatmentnaïve diabetic macular edema (DME) and good initial visual acuity (VA)

Methods: Retrospective cohort study following long-term natural history of eyes with untreated center-involving DME and baseline VA ≥ 20/25 seen at the University of California, Davis Eye Center between March 2007 to March 2018. We collected clinical characteristics including diabetes type, hemoglobin A1c, presence of visual symptoms, VA, and diabetic retinopathy (DR) severity; and spectral domain-optical coherence tomography (SD-OCT) biomarkers including central subfield thickness, intraretinal cyst size, intraretinal hyperreflective foci, disorganization of the retinal inner layers (DRIL), and outer retinal layer disruptions, to determine factors associated with vision loss as defined by the DRCR Protocol V study as threshold for initiating aflibercept therapy.

Impact of portable artificial vision device (OrCam Read) on visionrelated quality-of-life in patients with low vision due to TBI

Wed, 30 Oct 2024 00:00:00 +0000

A traumatic brain injury (TBI) is an injury to the head that disrupts the function of the brain. Visual dysfunction occurs in over 70% of patients following a TBI. The commonly reported symptoms include photophobia, blurred vision, and visual field defect. Very limited evidence of vision-related rehabilitation is available. OrCam Read is a handheld artificial vision device comprised of a “smart” camera that reads texts from both printed surfaces and digital screens. It uses a laser to indicate reading and a camera captures an image and converts the text into audio, which is transmitted through the device’s speaker or Bluetooth devices.

The Burden of Eye Disease & Eye Care Utilization Pattern In Patients At An Asian Free Healthcare Clinic

Mon, 28 Oct 2024 00:00:00 +0000

Visual impairment decreases quality of life, impacts health outcomes, and places substantial economic burden in the United States. Racial/ethnic disparities exist in the rates of eye disease and eye care utilization, with Chinese Americans having lower rates of utilization than African Americans and whites. To meet the eye care needs of Sacramento’s large Asian community, U.C. Davis Eye Center and Paul Hom Asian Clinic (PHAC) partnered together to offer no-cost ophthalmologic services for underserved Asian Americans and immigrants. There is limited data examining patterns of eye disease prevalence and eye care utilization for high-risk populations in an Asian free healthcare clinic setting. Our study aims to understand these patterns at Paul Hom Eye Clinic and identify potential barriers related to follow-up management.

Misdiagnosis of Bell’s palsy: Literature Review

Tue, 22 Oct 2024 00:00:00 +0000

o Acute facial paralysis is a common neurologic condition that may be associated with significant morbidity and mortality.

o Bell’s palsy is the most reported cause of acute facial paralysis, accounting for 60-80% of cases.

o While Bell’s palsy is benign and associated with recovery in 85% of patients, its prevalence may contribute to physicians’ failure to recognize more insidious underlying causes.

Confocal Microscopy analysis of Human CD34+ Bone Marrow Stem Cells Intravitreal Injection on Retinal Capillary Layers in a Murine Model of Diabetic Retinopathy

Mon, 21 Oct 2024 00:00:00 +0000

Diabetic retinopathy remains the leading cause of blindness among working-age adults in the United States. Vision loss occurs because diabetes damages the retinal vessels. Currentl, retinal laser treatment and anti-VEGF injection therapy are availalbe to reduce vision loss from bleeding and retinal swelling associted with diabetic retinopathy. However, no treatment reverses the retinal vascular damage associated with diabetic retinopathy.

How is spinal cord function measured in degenerative cervical myelopathy? A systematic review

Wed, 16 Oct 2024 00:00:00 +0000

The most common cause of spinal cord dysfunction is degenerative cervical myelopathy. It manifests as spinal cord compression and neurological impairment. Since the spinal cord is complex and works with many organs, it is challenging to measure spinal cord function in patients with DCM. mJOA is widely used to assess DCM but is problematic due to comorbidities and interobserver bias.

Prevalence of Evaluation and Treatment of Osteoporosis After Low-Energy Hip Fractures at a Level 1 Academic Tertiary Care Trauma Center with a Multi-Disciplinary Geriatric Hip Fracture Program

Wed, 16 Oct 2024 00:00:00 +0000

Osteoporosis is a major public health issue, with more than 53 million people in the United States either having osteoporosis or at increased risk for developing osteoporosis. Osteoporosis places patients at risk for fragility fractures which are associated with a decreased health-related quality of life and substantial financial burden on the healthcare system. Previous studies discovered a low rate of osteoporosis evaluation and treatment in adult patients after a hip fragility fracture though these studies need to be updated to determine if improvements have occurred over the last decade. Thus, the primary aim of this study was to evaluate rates of osteoporosis evaluation and treatment in adult patients following low-energy hip fractures.

Do Peripheral Nerve Sizes Correlate with Optic Nerve Sheath Diameter?

In a sample of patients with subjectively normal intracranial pressure, median nerve size varied significantly with optic nerve sheath diameter.

Expansion of tele-ophthalmology for diabetic diabetic retinopathy screening during the COVID-19 pandemic

Thu, 10 Oct 2024 00:00:00 +0000

Diabetic retinopathy is the leading cause of blindness in working-age adults, ages 20-74. The tele-ophthalmology program was launch at UCD Health in 2018 and was expanded during the COVID-19 pandemic to improve early screening for diabetic retinopathy. Assess diabetic retinopathy screening utilization during the COVID-19 pandemic. Evaluate follow-up encounters and outcomes

A spontaneous cerebrospinal fluid (CSF) leak occurs when the CSF egresses from the subarachnoid space of teh anterior or middle cranial fossa into the surrounding sinonasal or middle ear cavities through a dehiscence of the lamia dorsa.

Why Does Pneumatic RetinopexyHave Such Varied Outcomes?

Wed, 28 Aug 2024 00:00:00 +0000

Pneumatic retinopexy (PR) is used to repair retinal detachments ideally in phakic patients who have a single break or multiple smaller breaks in the superior 8 clock hours of the fundus. The single-procedure success rate of PR is highly variable and has been reported to range between 43.7% and 95.5%, with a mean of 74.4% across all studies.
