Eyelid margin disease (blepharitis and meibomian gland dysfunction): clinical review of evidence-based and emerging treatments.

Blepharitis is a common ophthalmic condition with multiple etiologies and no definitive, universal treatment. The treatment modalities for managing lid margin diseases vary depending on the disease's cause, location, and severity. For anterior blepharitis, management options include eyelid hygiene with warm compresses, eyelid scrubs, baby shampoo, and over-the-counter eyelid cleansers. Topical antibiotics and antibiotic-steroid combination drops/ointments for the eye and eyelid may accompany these. For posterior blepharitis/meibomian gland dysfunction (MGD), at-home warm compress or in-office administration of heat therapy/thermal pulsation treatment that aims to clear obstruction in the meibomian glands and restore meibum secretions to maintain a healthy tear film is recommended. In addition to the above treatment strategies, various other compounds to manage lid margin diseases are in the late stages of development. This review summarizes the available treatment modalities or those in the pipeline for treating blepharitis and MGD.

Rosacea: The eyes have it.

Rosacea is a chronic inflammatory dermatosis typically affecting the facial skin but also the eyes. With its chronic course with fluctuating episodes of flashing, redness, papulopustules, and nodules it poses a severe psychologic burden to the affected individuals. In addition to the facial changes, more than half of the patients have ocular involvement ranging from blepharitis and conjunctival hyperemia to more severe ophthalmic damage, and even blindness. Clinically, the ocular involvement in rosacea includes meibomian gland dysfunction with relapsing hordeola and chalazia, diffuse hyperemic conjunctivitis, photophobia, episcleritis, or kerato-conjunctivitis, and in rare cases, corneal ulcers. These are mainly observed in adult patients but can also occur in children. Depending on the degree of cutaneous or ocular findings, patients with rosacea may present first to the dermatologist or to the ophthalmologist. Both specialists should be aware of the potential oculocutaneous involvement. Any ocular complaints expressed by the patient in the setting of a dermatologist's office should be referred promptly for an ophthalmologic examination. Conversely, signs suggestive of rosacea in the eye should lead the ophthalmologist to consider underlying skin disease. A timely interdisciplinary collaboration is paramount for the earlier diagnosis and treatment, thus preventing permanent eye impairment in this chronic dermatosis.

Meibomian gland dysfunction and blepharitis: A common and still unsolved ophthalmic problem.

Blepharitis and meibomian gland dysfunction (MGD) are very common, usually underdiagnosed and underappreciated diseases. More than 50% of patients seeking ophthalmologic consultations have symptoms and signs indicating one or both entities. We summarize the key points of diagnosis and management of both diseases, comparing the work of Dry Eye Workshop II (2017) with the dry eye blepharitis syndrome unification theory. The impact of MGD/blepharitis on ocular surgery also is described. Although MGD and blepharitis seem to be uncurable, most of the time they can be successfully controlled. Different management options are available, but the key to success remains simple-routine eyelid hygiene and moisturizing with the use of preservative-free lubricants.

Prospective evaluation of intense pulsed light treatment for meibomian gland dysfunction and blepharitis due to ocular rosacea

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. Clinical evaluation was based on: ocular surface disease index (OSDI) and symptom score questionnaires, quality of live and facial severity degree, non-invasive tear meniscus height, non-invasive tear break up time, corneal fluorescein staining and eyelid margin and meibomian gland assessment. Adverse effects on the eye and periocular area, and systemic complications were evaluated. Results: The OSDI questionnaire showed a decrease in symptoms, achieving normal values in 91.9% of patients. The symptom score showed amelioration, with the most significant changes relating to dryness, foreign body sensation, light sensitivity, and pain. Longitudinal analysis showed the most significant improvement between baseline at Day 1 and 49. All eyelid signs improved, most significantly for telangiectasia/vascularity and blepharitis, leading to a 78% clearance of facial rosacea and 81.1% reduction of flushing. In total, 100% of the patients reported an improvement in their quality of life after treatment and 94.6% a very significant improvement (p<0.001). Conclusion: These results demonstrate that Thermaeye Plus is an effective and safe treatment for ocular rosacea.

Safety and Efficacy of an Augmented Intense Pulse Light Protocol for Dry Eye Syndrome and Blepharitis.

Objective: We evaluated the safety and efficacy of an augmented BroadBand Light (BBL™) protocol on the upper and lower eyelids in improving meibomian gland dysfunction (MGD) and/or dry eye disease (DED). Background: DED, often associated with MGD, can cause significant morbidity and accounts for 3.54 billion U.S. dollars of health care spending yearly. Intense pulsed light (IPL) has been used to treat MGD DED with some success. BBL therapy, a high-quality IPL machine, shows much promise for decreasing inflammation and redness in rosacea, as well as hyperpigmentation from sun damage. Methods: A retrospective medical chart review was performed for MGD DED and/or hyperpigmentation patients who received BBL therapy between January 1, 2015, and February 28, 2020. Inclusion criteria included patients who underwent at least one BBL treatment. Each treatment involved the upper and lower eyelids, as well as cheeks, nose, and face. Each MGD DED subject completed the Ocular Surface Disease Index (OSDI) and underwent pre- and post-treatment standard clinical examinations. Results: Forty-seven patients had treatment without significant adverse effects; all patients with MGD DED reported improvement in their dry eye or blepharitis. BBL was determined to be a safe and effective treatment. There were no changes in visual acuity (p = 0.555) and OSDI scores were improved (p = 0.016). There was one case each of mild corneal/conjunctival abrasion, temporary hyperpigmentation, and two of temporary eyelash thinning. Patients with MGD also showed significant improvement in blepharitis and reduced hordeolum frequency after BBL treatment. Conclusions: This novel IPL/BBL protocol appears safe and effective for treating dry eye and blepharitis.

Ocular Surface Disorders in Patients with Human Immunodeficiency Virus (HIV) Infection.

Purpose: To describe ocular surface disorders associated with human immunodeficiency virus (HIV). Methods: Narrative review. Results: Ocular surface neoplastic conditions, such as Kaposi's sarcoma, conjunctival lymphoma and ocular squamous cell carcinoma along with blepharitis, dry eye disease, and vernal keratoconjunctivitis, constitute ocular surface complications in HIV-infected individuals. Conclusion: This review will provide a summary of clinical presentations and treatment options for the most common HIV-related ocular surface diseases, indicating the need for a comprehensive ocular examination including ocular surface in all HIV patients 22.

Ocular Surface Disease in Birds.

Avian ocular disease may be primary or a manifestation of systemic disease. Various infectious and noninfectious diseases have been reported to cause ocular pathology. Thorough physical examination and diagnostic testing are necessary to determine a treatment plan.

Comparing the in vitro effects of MGO™ Manuka honey and tea tree oil on ocular Demodex viability.

PURPOSE: To compare the in vitro antiparasitic effects of MGO™ Manuka honey and tea tree oil against ocular Demodex. METHODS: Fifty-two viable Demodex mites were acquired from the epilated eyelashes of 9 participants with blepharitis and symptomatic dry eye. Viable mites were randomised to one of five treatment groups: cyclodextrin-complexed and uncomplexed Manuka Honey, 100% and 50% tea tree oil, and no treatment. Following treatment application, mite viability was assessed for 240 min, based on limb and body movement and/or the development of a crenated/translucent appearance. Kaplan-Meier survival analysis was then performed. RESULTS: The log-rank test demonstrated a significant treatment effect on the survival distribution of Demodex mites (p < 0.001). Bonferroni-corrected post-hoc pairwise analysis showed that all treatments except for uncomplexed honey effected lower survival probabilities than the untreated group (all p < 0.001). Among the four treatments, survival probabilities were lowest with 100% tea tree oil (all p < 0.001), and highest with uncomplexed honey (all p ≤ 0.001). No difference was observed between complexed honey and 50% tea tree oil (p = 0.81). CONCLUSIONS: The in vitro efficacy of cyclodextrin-complexed Manuka honey was comparable with 50% tea tree oil, an established treatment for ocular Demodex. The findings support future clinical trials investigating the therapeutic effects of complexed honey in demodectic blepharitis patients.

Long-term effects of intense pulsed light treatment on the ocular surface in patients with rosacea-associated meibomian gland dysfunction.

PURPOSE: We aimed to determine the long-term effects of intense pulsed light (IPL) treatment in rosacea-associated meibomian gland dysfunction (MGD). METHODS: We enrolled 17 rosacea subjects with moderate and severe MGD who underwent four IPL sessions at 3-week intervals and were followed up for 12 months. The subjects underwent clinical examinations at baseline (first IPL) and at 3 (second), 6 (third), 9 (fourth), and 12 weeks, as well as 6 and 12 months, after baseline. Ocular surface parameters, including the Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), staining score, and noninvasive Keratograph tear break-up time (NIKBUT), as well as meibomian gland parameters, including the lid margin vascularity and meibum expressibility and quality, were evaluated. RESULTS: All ocular surface and meibomian gland parameters for all subjects exhibited significant changes from baseline to the final examination (Friedman, P < 0.050 for all). In particular, improvements in the lower lid margin vascularity, meibum expressibility and quality, and ocular symptoms persisted up to the final examination (Wilcoxon, P < 0.050 for all). However, the improvements of TBUT, staining score, and NIKBUT after IPL were not maintained at 6 and 12 months after baseline. CONCLUSIONS: In rosacea-associated MGD, four IPL treatments at 3-week intervals can improve long-term lid parameters and ocular symptoms without adverse effects.

Eyelid inflammation: An uncommon cause in occidental countries.

BACKGROUND: Myiasis designates the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) and is the fourth most common travel-associated skin disease. Furuncle is the most common aspect of cutaneous myiasis. CASE PRESENTATION: A 24-year-old Caucasian female had been back from Cap-Vert. She described pruritus, slight pain, and the sensation of a foreign body moving in the eyelid. Physical examination showed a single furuncle-like nodule with surrounding erythema and a central pore of the upper eyelid through which a serosanguinous fluid was exuding. A larval end was visible to the naked eye through the aforementioned pore. Treatment consisted of the application of petroleum jelly (Vaseline®) to produce localized hypoxia. A transparent occlusive dressing was set for a duration of 2 h. The larva, Cordylobia antropophaga, spontaneously externalized to breathe and was extracted. DISCUSSION: There is an increase in travelers returning from tropical countries. Consequently, travel-associated dermatoses are increasing in non-endemic countries. Context of travel and typical clinical presentation strongly suggested to evoke a cutaneous myiasis. The typical furuncular lesion is a papule or nodule with a central punctum that exudes serosanguinous or purulent fluid. Ultrasound can be used to confirm the diagnosis. Treatment consists of three techniques: methods producing localized hypoxia to force emergence of the larvae, application of toxic substances to the eggs and larvae, and mechanical or surgical debridement. Surgery and antibiotics are usually unnecessary. Prevention of furunculous myiasis is based on vector control and individual actions to improve hygiene.

[Pathophysiology of atopic blepharokeratoconjunctivitis]. / Pathophysiologie der atopischen Blepharokeratokonjunktivitis.

Atopic dermatitis (AD) is a systemic inflammatory disease, which is characterized by pronounced eczema and pruritus. In addition to the involvement of the entire integument, the periocular lid skin and the surface of the eye are frequently involved. Ocular involvement may occur solely without dermatitis of facial or body skin. Pathophysiologically, besides a dysregulated immune response, genetic changes can occur in various dermal structural proteins which will lead to a disturbed skin barrier. Furthermore, there is a regular colonization with bacterial pathogens and an increased susceptibility for viral skin infections. The lid margin reveals a loss of Meibomian glands whereas the conjunctiva shows reduced goblet cells. Consecutively, eye surface defects and recurrent conjunctival and corneal defects can be found. Increased mechanical manipulation in atopia-associated pruritus is seen as a cause of increased comorbidity with keratoconus. In addition, individual cases are reported of various malignomas of the eye surface, which are present in patients with AD. Understanding of the pathophysiological connections is essential for the correct diagnosis and therapy of this clinically very complex disease picture.

Carcinoma de glándulas sebáceas palpebrales / Carcinoma of palpebral sebaceous glands

El carcinoma de glándulas sebáceas es un tumor altamente maligno y potencialmente letal. Puede enmascarar enfermedades inflamatorias como blefaritis, blefaroconjuntivitis, meibomitis, tarsitis y chalazión recurrente. Por eso, ante la presencia de una lesión palpebral de presentación atípica o recidivante se impone una exéresis completa con margen oncológico para su estudio anatomopatológico. Esta afección cursa con un diagnóstico clínico difícil, y en ocasiones inadvertido, por lo que se realizó una revisión bibliográfica para profundizar en sus diferentes formas de presentación, pronóstico y tratamiento.

The sebaceous gland carcinoma is a highly malignant tumor and potentially lethal; it may masquerade inflammatory diseases such as blepharitis, blepharoconjunctivitis, meibomitis, tarsitis and recurrent chalazion. Hence, the presence of palpebral injury of recurrent or atypical presentation imposes a complete resection with oncological margin for pathological examination. This condition presents with difficult clinical diagnosis and sometimes unnoticed, so we conducted a literature review to delve into its various forms of presentation, prognosis and treatment.

Ocular inflammation and infection.

Ocular inflammation and infection may involve any part of the eye and surrounding tissue. A complete examination, including visual acuity, extraocular movements, pupillary response, slit lamp examination, and fluorescein staining, is often required to establish the diagnosis. Pain relief may be achieved with oral analgesics and cycloplegics. In most cases, prompt follow-up is required.

Diagnosis and management of red eye in primary care.

Red eye is the cardinal sign of ocular inflammation. The condition is usually benign and can be managed by primary care physicians. Conjunctivitis is the most common cause of red eye. Other common causes include blepharitis, corneal abrasion, foreign body, subconjunctival hemorrhage, keratitis, iritis, glaucoma, chemical burn, and scleritis. Signs and symptoms of red eye include eye discharge, redness, pain, photophobia, itching, and visual changes. Generally, viral and bacterial conjunctivitis are self-limiting conditions, and serious complications are rare. Because there is no specific diagnostic test to differentiate viral from bacterial conjunctivitis, most cases are treated using broad-spectrum antibiotics. Allergies or irritants also may cause conjunctivitis. The cause of red eye can be diagnosed through a detailed patient history and careful eye examination, and treatment is based on the underlying etiology. Recognizing the need for emergent referral to an ophthalmologist is key in the primary care management of red eye. Referral is necessary when severe pain is not relieved with topical anesthetics; topical steroids are needed; or the patient has vision loss, copious purulent discharge, corneal involvement, traumatic eye injury, recent ocular surgery, distorted pupil, herpes infection, or recurrent infections.

Emerging treatment paradigms of ocular surface disease: proceedings of the Ocular Surface Workshop.

The objective of the Ocular Surface Workshop in Rome, Italy, on 6 February 2009, was to enhance the understanding of ocular surface disease (OSD) through an exploration of the nature of its complexities and current treatment paradigms across Europe. It was hoped that the peer-to-peer discussions and updates regarding common knowledge, clinical practices and shared experiences at this workshop would subsequently shape future treatment approaches to OSD.

[Red eye in children]. / L'oeil roug chez l'enfant.

Red eye in children is a common consultation purpose. Mostly benign, this sign may also cause visual impairment. We differentiate three kinds of red eye: localised, diffused and perikeratic injection. The last one must be recognized because of its association with severe ocular diseases. Diagnosis must be sure and treatment has to be efficient to not pertubate childrens visual development. Unfortunately, physical examination on children is not always easy. Consultation with an ophthalmologist is justified if a doubt remains, in case of chronic pathology or resistance to first intention treatment.

Blepharitis: current strategies for diagnosis and management.

BACKGROUND: The aim of this article is to present a consensus on the appropriate identification and management of patients with blepharitis based on expert clinical recommendations for 4 representative case studies and evidence from well-designed clinical trials. METHODS: The case study recommendations were developed at a consensus panel meeting of Canadian ophthalmologists and a guest ophthalmologist from the U.K., with additional input from family doctors and an infectious disease/medical microbiologist, which took place in Toronto in June 2006. A MEDLINE search was also conducted of English language articles describing randomized controlled clinical trials that involved patients with blepharitis. RESULTS: Blepharitis involving predominantly the skin and lashes tends to be staphylococcal and (or) seborrheic in nature, whereas involvement of the meibomian glands may be either seborrheic, obstructive, or a combination (mixed). The pathophysiology of blepharitis is a complex interaction of various factors, including abnormal lid-margin secretions, microbial organisms, and abnormalities of the tear film. Blepharitis can present with a range of signs and symptoms, and is associated with various dermatological conditions, namely, seborrheic dermatitis, rosacea, and eczema. The mainstay of treatment is an eyelid hygiene regimen, which needs to be continued long term. Topical antibiotics are used to reduce the bacterial load. Topical corticosteroid preparations may be helpful in patients with marked inflammation. INTERPRETATION: Blepharitis can present with a range of signs and symptoms, and its management can be complicated by a number of factors. Expert clinical recommendations and a review of the evidence on treatment supports the practice of careful lid hygiene, possibly combined with the use of topical antibiotics, with or without topical steroids. Systemic antibiotics may be appropriate in some patients.
