Ocular rosacea

Infestation with Demodex mites is a common occurrence, especially in adults and the elderly. More recent attention has been paid to the presence of Demodex spp. mites in children, even ones without comorbidities. It causes both dermatological and ophthalmological problems. The presence of Demodex spp. is often asymptomatic, thus it is suggested to include parasitological investigation tests in dermatological diagnostics, in addition to bacteriological analysis. Literature reports show that Demodex spp. are related to the pathogenesis of numerous dermatoses, including rosacea or demodicosis gravis, and common eye pathologies reported by patients such as dry eye syndrome or ocular surface inflammatory conditions, such as blepharitis, chalazia, Meibomian gland dysfunction, and keratitis...

BACKGROUND: Rosacea is a cutaneous disease that may secondarily affect the ocular surface. Due to the vision threatening, cosmetic, psychological, and work productivity impact, the identification of cellular targets that govern rosacea would enhance our understanding of the biology of the disease and delineate targets for therapeutic manipulation. OBJECTIVE: To characterize the involvement of SH2 domain-containing protein tyrosine phosphatase-2 (SHP2) in the pathogenesis of rosacea...

BACKGROUND: Ocular rosacea is common and is often managed with long-term antibiotic treatment. Doxycycline is the most commonly selected antibiotic for the treatment of rosacea. As there is no established standard of care treatment dose for rosacea, prescribed doses of doxycycline vary widely. The FDA classifies 40 mg daily dose of doxycycline for ocular rosacea as sub-microbial in comparison to an antibiotic dose of 200 mg daily. However, this "sub-microbial" dose has never been evaluated in patients with ocular rosacea, and even the sub-microbial dose has potential to alter systemic mucosa flora...

PURPOSE: Inflammation plays a role in diabetic eye diseases, but the association between rosacea and eye diseases in patients with diabetes remains unknown. DESIGN: This retrospective cohort study used claims data from the National Health Insurance Research Database in Taiwan to investigate the association between rosacea and eye diseases in patients with diabetes. MATERIALS AND METHODS: Taiwanese patients diagnosed as having diabetes mellitus between January 1, 1997, and December 31, 2013, and using any hypoglycemic agents were included and divided into rosacea and nonrosacea groups...

Purpose: Dry eye disease (DED) is a heterogeneous condition with poorly characterized subtypes. The DREAM study was a large multicenter randomized clinical trial that did not find omega-3 to be more effective than placebo in treating symptomatic DED. We performed secondary analysis of DREAM data to characterize DED subtypes and their omega-3 response. Methods: A total of 535 patients with moderate-to-severe DED were randomized to omega-3 or placebo treatment for one year...

Background: An overlap between the skin disease rosacea and the headache disease migraine has been established; however, the magnitude of this overlap and the distribution between subtypes/phenotypes remains unclear. Objective: The aim was to determine the magnitude of the overlap between rosacea and migraine, and to determine which subtypes/phenotypes were present in patients with concomitant rosacea and migraine. Methods: In this cross-sectional study, 604 patients with a diagnosis of either rosacea or migraine were phenotyped through a face-to-face interview with clinical examination, to determine prevalence and phenotype of rosacea, and prevalence and subtype of migraine...

INTRODUCTION: Rosacea is a chronic and relapsing facial dermatosis that encompasses a wide spectrum of clinical phenotypes (transient/persistent erythema, telangiectasias, papules/pustules, edema, phymatous changes, and ocular symptoms) often with uncomfortable symptoms such as flushing, pain, burning, edema, and dryness. Current pharmacological treatment includes topical agents, spanning from several conventional (azelaic acid, metronidazole, sodium sulfacetamide) to new ones (brimonidine, oxymetazoline, ivermectine, minocycline), and systemic agents (doxycycline 40 mg modified-release), all Food and Drug Administration approved...

BACKGROUND: Ocular rosacea is a chronic inflammatory disorder with periods of exacerbation and remission, often underdiagnosed in children. When diagnosed, its management is challenging because of a lack of effective long-term treatment options. OBJECTIVE: To report our experience in cases of pediatric ocular rosacea treated with moist heat therapy and topical azithromycin 1.5%. METHODS: The medical records of six children diagnosed with ocular rosacea based on a careful medical history and slit-lamp examination of the eyelids and ocular surface were reviewed...

BACKGROUND: Ocular rosacea is a common skin condition leading to dry eye that is difficult to manage. OBJECTIVES: To estimate the efficacy and safety of a new intense pulsed light device, Thermaeye Plus, for meibomian gland dysfunction and blepharitis due to ocular rosacea. MATERIALS & METHODS: This prospective, longitudinal study included 74 eyes of 37 consecutive patients with ocular rosacea, with mean age of 45.6±11.7 years. Four consecutive sessions were undertaken, including14 flashes with 10 J/cm² on the periocular area and facial cheeks on Day 1, 14, 28, and 49...

PURPOSE: Management of ocular rosacea is challenged by the limited evidence-based systemic treatment guidelines and lack of elucidated mechanisms of treatment efficacy. METHODS: We conducted an online survey of clinicians who regularly treat ocular rosacea to elicit their opinions on treatment algorithms and understanding of the treatment's primary mechanism of action. Descriptive statistics and univariate comparisons were reported. RESULTS: One hundred thirty-two participants completed the online survey...

INTRODUCTION: The relationship between facial dermatoses and blepharitis has been known for a long time. OBJECTIVES: We aimed to investigate the frequency of accompanying facial dermatoses in patients with blepharitis and their relationship with the severity of blepharitis. METHODS: In this cross-sectional study, 95 patients with blepharitis were examined for attending facial dermatoses. The type of blepharitis, the severity of blepharitis, and the degree of dry eye were determined in the patients...

INTRODUCTION: Ocular Rosacea is a poly etiological chronic inflammatory disease with heterogeneous clinical manifestations. It is primarily a dermatologic disease, which often manifests in the eyes affecting eyelids, conjunctiva, and cornea. The leading role in the pathological process belongs to the disruption of regulatory mechanisms in the vascular, immune, and nervous systems. The varied manifestation can be erythematous pustular lesions on the face, chronic blepharitis, meibomian gland dysfunction, evaporative dry eye, peripheral corneal ulceration, corneal scarring, perforation, and neovascularization...

This updated and upgraded S2k guideline deals with the diagnosis and treatment of rosacea, which is a common, chronic inflammatory skin disease mostly affecting the face. Initially, rosacea is characterized by recurrent erythema, telangiectasia and flushing. Later, the inflammatory component predominates, with persistent erythema with follicular papules, papulopustules and pustules. The development of phyma, which usually occurs on the acral localizations, is the most severe manifestation. For the treatment of rosacea, the interdisciplinary guideline committee, with representatives of the German Dermatological Society (DDG), the Professional Association of German Dermatologists (BVDD), the German Opthalmological Society (DOG), the Society for Dermopharmacy (GD), the Swiss Society for Dermatology and Venereology (SGDV) and the German Rosacea Aid e...

Sight is arguably the most important sense in human. Being constantly exposed to the environmental stress, irritants and pathogens, the ocular surface - a specialized functional and anatomical unit composed of tear film, conjunctival and corneal epithelium, lacrimal glands, meibomian glands, and nasolacrimal drainage apparatus - serves as a crucial front-line defense of the eye. Host defense peptides (HDPs), also known as antimicrobial peptides, are evolutionarily conserved molecular components of innate immunity that are found in all classes of life...

PURPOSE: To compare the safety and efficacy of intense pulsed light (IPL) followed by meibomian gland expression (MGX), against monotherapy of MGX. METHODS: Patients with moderate to severe meibomian gland dysfunction (MGD) were 1:1 randomized to 4 sessions of intense pulse light + MGX at 2-week intervals, or 4 sessions of Sham + MGX at 2-week intervals. Both patients and examiners were blinded to the allocation. Outcome measures, evaluated at the baseline (BL) and at a follow-up (FU) conducted 4 weeks after the last IPL session, included fluorescein tear breakup time (TBUT) as the primary outcome measure, OSDI (Ocular Surface Disease Index) questionnaire, Eye Dryness Score (EDS, a visual analog scale (VAS)-based questionnaire), Meibomian gland score (MGS, a score of meibum expressibility and quality in 15 glands on the lower eyelid), daily use of artificial tears, and daily use of warm compresses...

Rosacea is a common inflammatory skin disorder affecting the face. Common cutaneous symptoms include papules, pustules, persistent centrofacial erythema, telangiectasias, recurrent flushing, phymatous changes and a variety of ocular manifestations. Previous epidemiological studies have demonstrated that the incidence of rosacea is much lower in people with darker Fitzpatrick phototypes compared to fair-skinned individuals. In patients with darker skin, the centrofacial erythema can be masked and difficult to appreciate, impacting the ability for providers to make diagnoses and leading to misdiagnoses...

Background: Since medication absorption through the skin and eye tissue seems similar, commercially available eye-drops could be used to treat skin diseases when topical therapies are unavailable or unaffordable. The FDA-approved and off-label applications of various eye drops used as topical treatments in dermatological clinical practice were highlighted in this review. Methodology: A thorough PubMed and Google Scholar library search using various combinations of the keywords (Eye drop, ocular solution, conjunctival installation, and skin diseases, topical, local, beta-blockers, prostaglandin, cyclosporin, apraclonidine, atropine, oxymetazoline)...

BACKGROUND AND OBJECTIVES: Ocular rosacea is a special manifestation of rosacea with unknown etiology. Eye involvement in rosacea patients is surprisingly common; however, it is often underdiagnosed, resulting in inappropriate treatment. We aimed to provide an updated epidemiologic perspective on ocular rosacea in Germany to improve patient care. PATIENTS AND METHODS: Data of 777 rosacea patients were assessed using a detailed online questionnaire regarding ocular and skin symptoms, previous dermatological and ophthalmological consults, presence of type 1 hypersensitivities, and Demodex testing...
