Quantitative Analysis of Retinal Structure and Function in Two Chromosomally Altered Mouse Models of Down Syndrome.

PURPOSE: Ophthalmic disorders are among the most prevalent Down syndrome (DS) comorbidities. Therefore, when studying mouse models of DS, ignoring how vision is affected can lead to misinterpretation of results from assessments dependent on the integrity of the visual system. Here, we used imaging and electroretinography (ERG) to study eye structure and function in two important mouse models of DS: Ts65Dn and Dp(16)1Yey/+. METHODS: Cornea and anterior segment were examined with a slit-lamp. Thickness of retinal layers was quantified by optical coherence tomography (OCT). Eye and lens dimensio

Pupillary autonomic denervation with increasing duration of diabetes mellitus.

BACKGROUND/AIMS: The autonomic pupillary changes in type I and II diabetic patients without clinical evidence of diabetic autonomic neuropathy (DAN) were compared with age matched controls. The relation between pupillary and cardiovascular autonomic function was assessed in the diabetic patients. METHODS: A case-control study was performed with diabetics grouped according to type and duration of diabetes. Static infrared pupillography was used to compare mean dark adapted pupil size and mean percentage changes in pupil size with pilocarpine 0.1% and cocaine 4% in the diabetic and control grou

Современный подход к диагностике диабетической ретинопатии

В этой статье рассматриваются инновационные методы диагностики диабетической ретинопатии, поскольку распространение сахарного диабета и его осложнений продолжает расти. Новые методы сосредоточены на раннем обнаружении заболеваний. Технологические новшества, такие как телеофтальмология, смартфонная фотография, искусственный интеллект с глубоким обучением или широкополосная фотография, могут повысить диагностическую точность и ускорить лечение. В ходе обзора в качестве перспективных решений для дистанционного офтальмологического обслуживания рассматриваются телеоптальмология и ручная фотография.

[Optic neuropathy in positive anti-MOG antibody syndrome].

INTRODUCTION: The diagnosis of optic neuritis (ON), or inflammation of the optic nerve, is based on clinical findings: first marked by rapidly progressive visual decline associated with eye pain accentuated by eye movements; abnormalities of color perception and/or contrast sensitivity may also be reported. In this case, inflammatory neuropathies are associated with anti-MOG antibodies. MOGs, oligodendrocytic glycoproteins involved in the production of myelin, were identified nearly three decades ago in association with demyelinating ON. The first series were reported in children following dem

Sodium hypochlorite chemical burn in an endodontist's eye during canal treatment using operating microscope.

INTRODUCTION: This study describes a case of eye burn induced by sodium hypochlorite used as an irrigant during root canal preparation. METHODS: A 24-year-old female endodontist was using an operating microscope during root canal treatment, and as the root canal was irrigated, the pressure cannula burst and the irrigant (3.5% sodium hypochlorite) came into direct contact with her left eye. She immediately sought ophthalmologic emergency care for pain, redness of the cornea, burning sensation, photophobia, intraocular pressure, and blurred vision. The initial treatment consisted of washing the

Anti-obesity effect of MPV-1743 A III, a novel imidazoline derivative, in genetic obesity.

MPV-1743 A III ((+/-)-4-(5-fluoro-2,3-dihydro-1H-inden-2-yl)-1H-imidazole) is a novel imidazoline derivative. In this study, it was shown to bind with high affinity to alpha2-adrenoceptor subtypes alpha2A (IC50) = 0.66 +/- 0.06 nM), alpha2B (IC50) = 3.8 +/- 0.53 nM), alpha2C (IC50) = 3.1 +/- 0.61 nM) in the recombinant S115 cells and to alpha2D (IC50 = 0.94 +/- 0.10 nM) in the rat submandibular gland. MPV-1743 A III also showed remarkably high affinity to alpha1-adrenoceptors (IC50 = 150 +/- 12 nM) in the rat cerebral cortex and to imidazoline I2b-binding sites (IC50) = 150 +/- 5.0 nM) in the

Связь между 25-hydroxyvitamin D в виде жидкой хроматографии-тандем масс-спектрометрии и ретинопатии по типу 2 Болит диабет.

В этом исследовании изучается взаимосвязь между 25-hydroxyvitamin D (25(OH)D) уровни и диабетическая ретинопатия (DR) у пациентов типа 2 - сахарный диабет (T2DM). Участники были разделены на две группы: 3 групп населения на основе 25(OH)D статус: нормальная (группа A), недостаточная (группа B) и неудовлетворительная (группа C). В исследовании анализируется взаимосвязь между 25(OH)D и DR, а также его связь с различными клиническими параметрами. У пациентов T2DM 25(OH)D уровни были в значительной степени коррелированы с сывороточным фосфором (P), сывороткой кальция (Ca), апартатом аминопереносаз

AI-assisted diagnosis of neuro-ophthalmic disorders: a systematic review from optic neuritis to papilledema.

BACKGROUND: Neuro-ophthalmic disorders like optic neuritis and papilledema are diagnostically challenging, with non-specific symptoms and reliance on expert interpretation of optic nerve head imaging (Liu TYA et al. J Neuroophthalmol. 41(3):368–74, 2021). Misdiagnosis can lead to severe consequences, including irreversible vision loss or failure to detect life-threatening conditions. Artificial intelligence (AI), particularly deep learning (DL), shows promise but its application in this nuanced field is not well-defined. OBJECTIVE: This systematic review evaluates the current state of AI in di

Ангиография оптической согласованности — полезное средство для отличия первичного феномена Рейно от системного склероза и/или очень ранней болезни системного склероза.

Цель этого межсекторального исследования заключалась в сопоставлении результатов оптической ангиографии, полученной пациентами, с первичным явлением Рейно (PRP; n = 22), очень раннее заболевание системного склероза (VEDOS; n = 19), и системный склероз (SSc; 25 пациентов с ограниченным количеством SSc (lcSSc) и 13 - пациентов с диффузным резиновым SSc (dcSSc)). Целые, парафовиальные и перифовенные поверхностные капиллярные сплексы (ПХФ) плотность судна (ДГ), глубокие капиллярные сплетения VD и целые, внутренние и перипапольные VD были значительно выше в группе ПРП (p) < 0.001). В группе IcSSc п

Manifestations of systemic disease in the retina and fundus of cats and dogs.

The fundus is unique in that it is the only part of the body that allows for a noninvasive and uninterrupted view of vasculature and nervous tissue. Utilization of this can be a powerful tool in uncovering salient incidental findings which point to underlying systemic diseases, and for monitoring response to therapy. Retinal venules and arterioles allow the clinician to assess changes in vascular color, diameter, outline, and tortuosity. The retina and optic nerve may exhibit changes associated with increased or decreased thickness, inflammatory infiltrates, hemorrhages, and detachments. While

… In addition, contraindications to using mydriatics (e.g., glaucoma, lens luxation), challenges with pupillary dilation (e.g., pharmacologic or pathologic miosis) may hinder the exam. It is of note, that at times even a partial view of the fundus can offer valuable insight. …

Drug-Induced Periocular and Ocular Surface Disorders: An EAACI Position Paper.

Various systemic and topical medications can induce ocular and periocular cutaneous adverse effects (AEs), ranging from mild to severe. These AEs may lead to ocular surface (OS) damage and, in some cases, life-threatening complications. Drug-induced ocular adverse reactions are generally classified into two primary categories: toxic reactions and/or allergic hypersensitivity reactions, which can be IgE or non-IgE-mediated. Systemic antibiotics, antivirals, and anticonvulsants can trigger adverse reactions that may involve the OS. Drugs like antihistamines, beta-blockers, antipsychotics, antide

A review on clinical cases of rare mold infections and their antifungal treatment strategies.

In recent years, with the growing population of immunocompromised individuals, infections caused by rare environmental molds have become increasingly prevalent and clinically significant. Due to frequent misdiagnosis and difficult clinical management, the overall disease burden of such infections poses a major challenge in clinical practice. This article aims to fill the knowledge gap by reviewing cases of rare mold infections from January 2020 to February 2026, analyzing the susceptible populations, identification techniques, antifungal susceptibility testing, and antifungal treatment strateg
