Lid inflammation

We tested the efficacy of 4'-fluorocannabidiol (4'-F-CBD), a semisynthetic cannabidiol derivative, and HU-910, a cannabinoid receptor 2 (CB2) agonist in resolving l-DOPA-induced dyskinesia (LID). Specifically, we were interested in studying whether these compounds could restrain striatal inflammatory responses and rescue glutamatergic disturbances characteristic of the dyskinetic state. C57BL/6 mice were rendered hemiparkinsonian by unilateral striatal lesioning with 6-OHDA. Abnormal involuntary movements were then induced by repeated i...

Ocular malakoplakia, a rare inflammatory disorder characterized by Michaelis-Gutmann bodies, is presented in 2 unique cases involving uncommon anatomical sites-the orbit and caruncle. The first case describes a 10-year-old girl with localized subconjunctival swelling near the caruncle, prompting surgical excision, and revealing characteristic malakoplakia features. Despite medical management, surgical intervention provided symptom relief. The second case involves a painless swelling below the lower lid in a 23-year-old female, initially suggestive of lymphoma...

Systemic sclerosis (SSc) is a chronic multisystemic disease characterized by immunological activation, diffuse vasculopathy, and generalized fibrosis exhibiting a variety of symptoms. A recognized precursor of SSc is Raynaud's phenomenon, which is part of the very early disease of systemic sclerosis (VEDOSS) in combination with nailfold videocapillaroscopy (NVC) impairment. The pathophysiology of ocular involvement, alterations in internal organs, and body integumentary system involvement in SSc patients are complicated and poorly understood, with multiple mechanisms presumptively working together...

PURPOSE: To study the demographic, clinical, and microbiological profile of Demodex-related blepharokeratoconjunctivitis (BKC) at a tertiary eye care hospital. METHODS: This retrospective observational study was conducted from January 2016 to September 2022. It included 83 patients with microbiologically proven Demodex BKC who presented to the cornea department of our tertiary care eye center. The clinical, microbiological, and demographic data of the 83 cases were analyzed...

BACKGROUND: Substance use disorder is associated with unhealthy lifestyle choices, resulting in adverse social and health consequences. People with opioid use disorder receiving opioid agonist therapy, in particular, have high morbidity and reduced quality of life. Physical activity is recommended as an adjunctive treatment for people with substance use disorder, but there is minimal evidence from randomized controlled trials on the effects of this among people with substance use disorder receiving opioid agonist therapy...

OBJECTIVES: To evaluate the validity and reliability of the new Fast Assessment of the Ocular Surface Trouble (FAST®) questionnaire for identifying glaucoma or ocular hypertension (OHT) patients at risk of ocular surface disease (OSD). METHODS: A multicenter, international, cross-sectional, epidemiological survey evaluated the most accurate interview items and ocular signs on the initial 14-item version of FAST® to develop a shorter version for routine, quick clinical use...

Blepharitis is a common chronic inflammatory condition affecting the eyelid margins; the pathophysiology of blepharitis is complex and not fully understood. The disease is anatomically divided into anterior (inflammation of eyelashes) and posterior (meibomian gland dysfunction) types. Diagnosis relies on clinical examination, revealing characteristic features like scurf, vascular changes, and meibomian gland dysfunction. The main goals of blepharitis treatment are symptom relief, recurrence prevention, and complication risk minimization...

Corticosteroids are commonly used in the treatment of inflammatory low back pain, and their nominal target is the glucocorticoid receptor (GR) to relieve inflammation. They can also have similar potency at the mineralocorticoid receptor (MR). The MR has been shown to be widespread in rodent and human dorsal root ganglia (DRG) neurons and non-neuronal cells, and when MR antagonists are administered during a variety of inflammatory pain models in rats, pain measures are reduced. In this study we selectively knockout (KO) the MR in sensory neurons to determine the role of MR in sensory neurons of the mouse DRG in pain measures as MR antagonism during the local inflammation of the DRG (LID) pain model...

PURPOSE: To evaluate the safety and efficacy of Lotilaner ophthalmic solution 0.25% in the treatment of demodex blepharitis. METHODS: PubMed, Web of Science, Scopus, and Embase databases were searched. RCTs comparing lotilaner with placebo or any other standard treatments were included. Outcomes of mean collarette grade (MCG), mite density (Md), meaningful collarette reduction (MCR), mite eradication (ME), were pooled as mean difference (MD), and the outcomes of erythema cure (EC), collarette cure (CC) adverse events (AE) as risk ratio (RR) with their 95% confidence interval (CI) between the two groups from baseline to the endpoint...

PURPOSE: Graves' orbitopathy (GO) is an autoimmune disorder leading to inflammation, adipogenesis, and fibrosis. The severity of GO can vary widely among individuals, making it challenging to predict the natural course of the disease accurately, which is important for tailoring the treatment approach to the individual patient. The aim of this study was to compare the clinical characteristics, course, treatment, and prognosis of GO patients under 50 years with older patients. METHODS: We reviewed the medical records of a random sample of 1000 patients in our GO database Essen (GODE) comprising 4260 patients at our tertiary referral center...

PURPOSE: To evaluate the effect of subconjunctival dexamethasone compared to normal saline on conjunctival autograft harvesting in patients undergoing pterygium surgery. METHODS: Fifty-two eyes of 52 patients who underwent pterygium excision combined with autologous conjunctival graft (CAG) using releasable suture were included in this prospective interventional study. The patients were randomized into two groups of 26 patients each. Group A consisted of patients in whom CAG was harvested using subconjunctival 0...

Panton-Valentine leukocidin (PVL) is a pore-forming exotoxin produced by certain Staphylococcus (S.) aureus strains, which is responsible for the increased virulence of the pathogen. Thus, infections caused by PVL-positive S. aureus tend to recur. Usually, the infection is a smear infection, which can cause folliculitis and purulent lid margin inflammation in addition to the classic mucocutaneous abscesses. Recently, recurrent genitoanal infections caused by PVL-positive S. aureus have also been described...

L-Dopa, while treating motor symptoms of Parkinson's disease, can lead to debilitating L-Dopa-induced dyskinesias, limiting its use. To investigate the causative relationship between neuro-inflammation and dyskinesias, we assessed if striatal M1 and M2 microglia numbers correlated with dyskinesia severity and whether the anti-inflammatories, minocycline and indomethacin, reverse these numbers and mitigate against dyskinesia. In 6-OHDA lesioned mice, we used stereology to assess numbers of striatal M1 and M2 microglia populations in non-lesioned (naïve) and lesioned mice that either received no L-Dopa (PD), remained non-dyskinetic even after L-Dopa (non-LID) or became dyskinetic after L-Dopa treatment (LID)...

Purpose To clarify the ocular surface features of patients with recent history of epidemic keratoconjunctivitis (EKC) and the relation between corneal dendritic cells (DCs) and ocular discomfort. Methods Normal controls (NC) and dry eye (DE) patients without EKC were recruited. Patients with recent EKC history (onset >4 weeks, but <20 weeks) were recruited as EKC + DE group (with dry eye) or EKC-DE group (without dry eye). Ocular Surface Disease Index (OSDI) questionnaire, tear film parameters including lipid layer thickness, first tear break-up time (fBUT), average tear break-up time (aBUT), tear meniscus height and Schirmer I test, meibomian gland parameters, and in vivo corneal confocal microscopy were evaluated...

INTRODUCTION: This two-part study aimed to investigate the therapeutic potential of topical spironolactone in ocular graft-versus-host disease (oGVHD). While off-label use of topical spironolactone has been described in dry eye, its efficacy in managing signs and symptoms of oGVHD remains unstudied. Preclinically, we tested the hypothesis that spironolactone induces corneal lipid synthesis in a mouse model. Clinically, we assessed patient response to spironolactone with a retrospective observational design...

Neonatal orbital complications are rare and potentially fatal, demanding prompt diagnosis and adequate treatment. A 25-day-old neonate presented with rapidly progressive orbital complications as evidenced by proptosis, chemosis, lid oedema and restricted eye movements, developing within 3 days. There was no significant medical history or risk factors for developing infection. An initial conservative approach with antimicrobial therapy failed to show any resolve. An MRI brain, orbits and paranasal sinuses demonstrated that there were features suggestive of right orbital cellulitis with possibility of abscess formation with right ethmoidal mucoinflammatory disease and mass effect on the optic nerve causing stretching and compression by the surrounding inflammation...

BACKGROUND/AIMS: Trachomatous trichiasis (TT) is a severe consequence of chronic inflammation/conjunctival scarring resulting from trachoma, the leading infectious cause of blindness worldwide. Our prospective cohort study evaluated the effectiveness of refresher training (RT) for experienced surgeons (1-22 years) on the outcomes of upper lid (UL) TT surgery in rural Ethiopia. METHODS: Patients undergoing UL TT surgery in at least one eye by a participating surgeon were included...

We report on the case of a Hispanic woman with necrobiotic xanthogranuloma (NBX) whose disease was managed based on her symptoms. She underwent a diagnostic and debulking surgical intervention and surveillance for hematologic malignancy. This 56-year-old patient presented with a six-year history of enlarging masses and swelling around her eyes, with intermittent inflammation, associated pain, and occasional redness. Her past medical history was remarkable for asthma and nasal polyps. Upon external examination, she had severe fullness of the upper lids with yellow plaques and palpable masses along them, nontender palpation, the absence of visible erythema, and blepharoptosis in both eyes...

AIM: To report ocular changes in rabbits after the implementation of three different induction methods to create dry eye (DE) conditions and provides evidence of DE-related disease evolution. METHODS: Experimental methods were divided into 3 models. The first model used involved triple injection of complete Freund's adjuvant, 50 µL each, also called the meibomian gland dysfunction (MGD) model. In the second model, DE conditions were created by the resection of nictitating membranes (NM), Harderian glands (HG), and main lacrimal glands (LG), also called the LGR model...

Meibomian gland dysfunction (MGD) is associated with evaporative dry eye syndrome, which is characterized by a reduction in meibum secretion and tear film instability. Present treatments provide only temporary relief, thereby necessitating the exploration of novel therapeutic strategies for chronic treatment. This study aims to evaluate topical spironolactone, a medication with anti-mineralocorticoid, anti-androgenic, and anti-inflammatory properties, in treating dry eye. A retrospective observational study was performed on the medical records of 102 patients diagnosed with dry eye disease...
