Self-reported history of childhood vision impairment among older adults screened for dementia.

We investigated the relationship between self-reported history of visual impairment in youth and the development of dementia in later life using data from the Panel Study of Income Dynamics (PSID) household survey, which included the Eight-item Informant Interview to Differentiate Aging and Dementia (AD-8) screen. Adults with a reported history of childhood visual impairment were found to have significantly higher odds of positive dementia screening. After adjusting for confounders, we found a twofold increase in those reporting early visual impairment compared with those who did not report early visual impairment.

Vitamin D, PTH, and Lipid Dysregulation in Osteoarthritis: A Case-Control Study.

Introduction: Osteoarthritis (OA) is a degenerative joint disease characterized by cartilage degradation, bone remodeling, and pain. Recent evidence suggests that Vitamin D insufficiency, alterations in parathyroid hormone (PTH) levels, and dyslipidemia may play roles in the pathophysiology of OA, affecting calcium homeostasis and bone health. We investigated the association between Vitamin D, PTH levels, lipid profile, and calcium homeostasis in OA patients.

Documented Reperfusion of the Retina on Fluorescein Angiography after Administration of Intravenous Prostaglandin E1 for Central Retinal Artery Occlusion: A Case Report.

Central retinal artery occlusion (CRAO) can result in devastating permanent vision loss. Presently, there is no evidence-based treatment for CRAO that is widely accepted. In the literature, multiple studies propose intravenous (IV) prostaglandin E1 (IV PGE1) as a potential treatment option for patients with CRAO.

Case report: Blotchy skin in a puffy neonate: is there a new association?

Introduction: Purpura fulminans in the neonatal population is a rare but potentially life-threatening condition complicated by thrombosis, resultant vital organ necrosis, and gangrene of the extremities. Considering the rapid evolution of the pathogenetic mechanism, an index of suspicion, early identification, and prompt intervention are imperative for improved outcomes. The majority of purpura fulminans cases have an infectious etiology, but it is essential to consider other congenital and acquired causes.

Neurodevelopmental Outcomes of Preterm Infants Born <29 Weeks with Bronchopulmonary Dysplasia-Associated Pulmonary Hypertension: A Multicenter Study.

Objective: This study aimed to determine neurodevelopmental outcomes of preterm infants born at <29 weeks' gestational age (GA) with bronchopulmonary dysplasia and pulmonary hypertension (BPD-PH) at 18 to 24 months' corrected age (CA).

Study Design: In this retrospective cohort study, preterm infants born at <29 weeks' GA between January 2016 and December 2019, admitted to level 3 neonatal intensive care units, who developed BPD and were evaluated at 18 to 24 months' CA in the neonatal follow-up clinics were included. We compared demographic characteristics and neurodevelopmental outcomes between the two groups: Group I: BPD with PH and Group II: BPD with no PH, using univariate and multivariate regression models.

Demographic and clinical characteristics of age-related distance esotropia.

Background: Age-related distance esotropia (ARDE), is an acquired, small, comitant esodeviation that is greater at distance than at near. It occurs in older adult patients without a history of neurological event or prior strabismus. It has been observed more frequently in White adults than in other racial groups.

Toxoplasma Neuroretinitis.

Neuroretinitis is an inflammatory condition with rapid unilateral vision loss, optic disc edema, and macular star formation. While neuroretinitis is commonly due to infectious causes such as , neuroretinitis due to toxoplasmosis is uncommon. A 29-year-old male presents to our neuro-ophthalmology clinic on December 7, 2021, at the University of Arkansas for Medical Sciences with symptoms of left eye pain and blurred vision.

Mitochondrial Triglyceride Dysregulation in Optic Nerves Following Indirect Traumatic Optic Neuropathy.

The purpose of this work is to identify mitochondrial optic nerve (ON) lipid alterations associated with sonication-induced traumatic optic neuropathy (TON). Briefly, a mouse model of indirect TON was generated using sound energy concentrated focally at the entrance of the optic canal using a laboratory sonifier (Branson Digital Sonifier 450, Danbury, CT, USA) with a microtip probe. We performed an analysis of a previously generated dataset from high-performance liquid chromatography-electrospray tandem mass spectrometry (LC-MS/MS).

Subjects: A mouse model of indirect TON was generated using sound energy concentrated focally at the entrance of the optic canal using a laboratory sonifier with a microtip probe.

Clinical and Mechanistic Review of Amiodarone-Associated Optic Neuropathy.

Amiodarone-associated optic neuropathy (AAON) is a complex clinical diagnosis, requiring distinction from non-arteritic ischemic optic neuropathy (NAION) due to a shared at-risk patient population. Diagnosis of AAON is complicated by a varied clinical presentation and incomplete pathophysiologic mechanisms. This article reviews pertinent literature for describing and clinically delineating AAON from NAION, as well as newly reported protective mechanisms of insulin-like growth factor 1 (IGF-1) and PI3K/Akt against amiodarone-induced oxidative and apoptotic injury in retinal ganglion and pigment epithelial cells.

Retinal Degeneration Associated With the G1606A Mitochondrial Mutation.

The guanine-to-adenine substitution at nucleotide 1606 (G1606A) mutation in the mitochondrial DNA transfer RNA-valine gene has been reported to cause sensorineural deafness, ataxia, myoclonus, seizures, and mental retardation. This study hereby presents a single case report of a new retinal phenotype associated with this mutation: a middle-aged woman with retinal pigment epithelium stippling, atrophy, and peripapillary (retinal pigment epithelium) dropout on fundus examination. The patient was administered an empiric trial of a mitochondrial cocktail with close monitoring of her systemic symptoms.
