Talha M, Haris Ali M, Fatima E, Nadeem A, Ahmed A, Nashwan AJ. Efficacy and Safety of Lotilaner Ophthalmic Solution (0.25%) for the Treatment of Demodex Blepharitis: A GRADE Assessed Systematic Review and Meta-Analysis of Observational & Experimental Studies. Am J Ophthalmol 2024; 264:8-16. [PMID: 38513948 DOI: 10.1016/j.ajo.2024.03.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/06/2024] [Accepted: 03/17/2024] [Indexed: 03/23/2024]
Abstract
PURPOSE Several treatments have been in use for Demodex blepharitis, before the discovery of lotilaner, like tea tree oil and antibiotics; however, they either have irritable effects or systemic adverse effects, respectively. Lotilaner, a novel ectoparasiticide, has been proposed as a treatment for patients grappling with Demodex blepharitis. This review aims to assess the safety and efficacy of lotilaner in the treatment of Demodex blepharitis. DESIGN Systematic review and meta-analysis. METHODS An extensive search was conducted on PubMed, Cochrane Library, Scopus, and Google Scholar to find relevant literature till July 31, 2023 following the PRISMA guidelines. A total of 143 articles were retrieved by database searching, out of which 6 studies met the inclusion criteria and were included in the review. Four randomized controlled trials were included in the meta-analysis of mite eradication incidence. The review is registered with PROSPERO: CRD42023459997. RESULTS Lotilaner is effective in eradicating Demodex mites in individuals suffering from Demodex blepharitis according to RR for the intervention versus the control group of 3.55 (95% confidence interval [CI]: 2.87-4.40, P < .00001, I2 = 0%). The meta-analysis of clinically meaningful collarette score revealed the summary RR for the intervention versus the control group was 3.15 (95% CI: 2.56-3.89, P < 0.00001, I2 = 27%). In conclusion, the results of the included studies were comparable and consistent. CONCLUSIONS Our results indicated that lotilaner is an effective, well-tolerated, and promising drug in treating patients with Demodex blepharitis. Lotilaner administration and cost-effectiveness should now be contemplated for the study population as these constituents have a vital impact on its treatment success.

Misra S, Murthy SI, Joseph J. Clinical spectrum in microbiologically proven Demodex blepharokeratoconjunctivitis: An observational study. Indian J Ophthalmol 2024; 72:1049-1055. [PMID: 38459713 DOI: 10.4103/ijo.ijo_954_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 12/21/2023] [Indexed: 03/10/2024] Open
Abstract
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. RESULTS Of the 83 cases, 57 (68.67%) were younger than 40 years, and 25 (30.12%) were below 20. Most patients presented with a good visual acuity of 20/40 or better (93 eyes; 84.55%). The disease was unilateral in 55 patients and bilateral in 28. Cylindrical dandruff was the predominant presentation noted in 61 eyes (54.95%), followed by corneal scarring in 47 eyes (42.34%) and corneal vascularization in 40 eyes (36.04%). On light microscopy, 87.95% of the positive samples were identified as Demodex folliculorum , 7.23% as Demodex brevis , and 6.02% remained unidentified. Tea tree oil and lid scrubs eradicated the disease in most patients clinically (75/83, 90.36%). CONCLUSION The spectrum of BKC includes both lid signs and corneal involvement. It can be a cause of recurrent BKC and detection of the mite by microscopic evaluation of the lashes can confirm the diagnosis. In most cases, the tea tree oil can effectively manage this condition. However, low doses of topical steroids are needed to control the inflammation in patients with corneal involvement.

Efficacy and Safety of Lotilaner Ophthalmic Solution 0.25% for the Treatment of Demodex Blepharitis: A Meta-Analysis of Randomized Controlled Trials. Cont Lens Anterior Eye 2024; 47:102148. [PMID: 38514290 DOI: 10.1016/j.clae.2024.102148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 03/07/2024] [Accepted: 03/14/2024] [Indexed: 03/23/2024]
Abstract
PURPOSE Demodex blepharitis, often overlooked in ocular surface disease, involves Demodex mites, prevalent ectoparasites on human skin. Current treatments may not effectively eliminate these mites, prompting a need for targeted therapies. Lotilaner, an antiparasitic agent, shows promise. This systematic review and meta-analysis assesses 0.25% lotilaner ophthalmic solution's efficacy in reducing Demodex mite populations and its impact on ocular surface inflammation in Demodex blepharitis patients. METHODS A comprehensive literature search was performed in the PubMed and Cochrane Library databases from inception until February 2024 to identify relevant trials investigating the use of lotilaner in patients with Demodex blepharitis. The included studies were assessed for quality, and a meta-analysis was conducted to determine the overall treatment effects of lotilaner. Odds ratios (OR) and 95% confidence intervals (CIs) were calculated for binary variables. All statistical analyses were performed using the R Statistical Software. RESULTS Five studies met the inclusion criteria and were included in this systematic review and meta-analysis. Lotilaner demonstrated significant efficacy in Collarette Cure [OR = 6.64; 95 % CI 3.78 to 11.04; p < 0.00001, I2 = 62 %] %], clinically meaningful collarette reduction [OR = 6.21; 95 % CI 3.67 to 10.49; p < 0.00001, I2 = 90 %], and achieving at least 1-grade collarette improvement [OR = 5.12; 95 % CI (2.96 to 8.88); p < 0.00001, I2 = 90 %] compared to the placebo group. The treatment also resulted in mite eradication [OR = 6.18; 95 % CI 4.67 to 6.18; p < 0.00001, I2 = 34 %], reduction in mite density [OR = 9.37; 95 % CI 5.36 to 16.36; p < 0.00001, I2 = 84 %], and erythema cure [OR = 2.29; 95 % CI 2.24 to 3.39; p < 0.00001, I2 = 5 %] and composite cure [OR = 7.05; 95 % CI 3.66 13. 61; p < 0.00001, I2 = 11 %]. The study suggests that lotilaner is a promising therapeutic option for collarette and associated symptoms, but the high heterogeneity in some outcomes and limited long-term data warrant further research to confirm its effectiveness and safety. CONCLUSION This systematic review and meta-analysis provides robust evidence supporting the efficacy of 0.25% lotilaner ophthalmic solution in treating Demodex blepharitis. Approval of this targeted therapy represents a significant milestone in ophthalmology and offers a promising treatment option for patients with Demodex blepharitis. Eye care professionals should consider the potential benefits of lotilaner in managing and alleviating the symptoms associated with Demodex infestations on the eyelids. Further research and long-term follow-up studies are warranted to assess the safety and effectiveness of lotilaner in treating Demodex blepharitis.

Abstract
PURPOSE The aim of this study was to report clinical observations suggesting the efficacy of topical 1% 5-fluorouracil (5-FU) in treating Demodex -associated blepharitis. METHODS An observational retrospective review of 13 eyes from 13 individuals with conjunctival neoplastic lesions and concomitant Demodex lash infestation that received topical 1% 5-FU eye drops. Patients underwent slit-lamp examination at each follow-up visit. Clinical photographs of the lash line were obtained after treatment initiation. In a subset of patients, lashes were epilated bilaterally and microscopically analyzed for presence of Demodex mites before and after treatment initiation. RESULTS The mean age of the population was 68 ± 14 years (range: 30-84 years) and 92% were male. In all 13 patients, a marked reduction in cylindrical dandruff was noted in the treated eye by slit-lamp examination after 2 cycles of 5-FU. There was complete resolution of cylindrical dandruff in 10 of 13 treated eyes compared with 0 resolution of cylindrical dandruff in untreated eyes ( P = 0.0001). In the 6 patients who received epilation, the lashes from the treated eye showed no Demodex , whereas lashes from the fellow untreated eye revealed persistent Demodex . CONCLUSIONS Topical 1% 5-FU shows efficacy in treating Demodex -associated blepharitis. Further studies are indicated to reproduce our findings and evaluate the potential use of 5-FU as a treatment ingredient.

Abstract
Treatment of ocular diseases presents unique challenges and opportunities for the clinician and for the clinical pharmacologist. Ophthalmic pharmaceuticals, typically given as liquids, require consideration of solubility, physiological pH, and osmolarity, as well as sterility and stability, which in turn requires optimal pharmaceutics. Ocular tissue levels are challenging to obtain in humans, and the clinical pharmacokinetics is typically blood levels, which are primarily related to safety, rather than efficacy. The eye is a closed compartment with multiple physiological barriers with esterases and transporters, but relatively little cytochrome oxidases. Delivery routes include topical, intravitreal, and systemic. Patient dosing involves not only adherence issues common to all chronic diseases, but also performance requirements on eye drop instillation. Therapeutically, ocular diseases and their pharmacological treatments include both those analogous to systemic diseases (e.g., inflammation, infection, and neuronal degeneration) and those unique to the eye (e.g., cataract and myopia).

Abstract
With 54 new drugs and seven cellular and gene therapy products, the approvals by the US Food and Drug Administration (FDA) recovered 2023 from the 2022 dent back to the levels of 2020-2021. As in previous years of this annual review, we assign these new drugs to one of three levels of innovation: first drug against a condition ("first-in-indication"), first drug using a novel molecular mechanism ("first-in-class"), and "next-in-class," i.e., a drug using an already exploited molecular mechanism. We identify four (7%) "first-in-indication," 22 (36%) "first-in-class," and 35 (57%) "next-in-class" drugs. By treatment area, rare diseases (54%) and cancer drugs (23%) were once again the most prevalent (and partly overlapping) therapeutic areas. Other continuing trends were the use of accelerated regulatory approval pathways and the reliance on biopharmaceuticals (biologics). 2023 marks the approval of a first therapy based on CRISPR/Cas9 gene editing.

Abstract
SIGNIFICANCE Patients with Demodex blepharitis have a considerable symptomatic burden that negatively impacts their daily activities and well-being. Despite chronic manifestations of and problems associated with blepharitis that resulted in multiple visits to eye care providers, Demodex blepharitis remained underdiagnosed or misdiagnosed. PURPOSE This study aimed to evaluate the effect of Demodex blepharitis on patients' daily activities and well-being. METHODS This prospective, multicenter, observational study recruited 524 patients with Demodex blepharitis from 20 U.S. ophthalmology and optometry practices. Demodex blepharitis was diagnosed based on the presence of the following clinical manifestations in at least one eye: >10 collarettes on the upper lashes, at least mild lid margin erythema of the upper eyelid, and mite density of ≥1.0 mite/lash (upper and lower combined). Patients were asked to complete a questionnaire related to their symptoms, daily activities, and management approaches. RESULTS The proportion of patients who experienced blepharitis symptoms for ≥2 years was 67.8%, and for ≥4 years, it was 46.5%. The three most bothersome symptoms ranked were "itchy eyes," "dry eyes," and "foreign body sensation." Overall, 77.4% of patients reported that Demodex blepharitis negatively affected their daily life. One-third (32.3%) of patients had visited a doctor for blepharitis at least two times, including 19.6% who visited at least four times. Despite having clinical manifestations of Demodex blepharitis confirmed by an eye care provider, 58.7% had never been diagnosed with blepharitis. Commonly used management approaches were artificial tears, warm compresses, and lid wipes. Among those who discontinued their regimen, 45.9% had discontinued because of either tolerability issues or lack of effectiveness. Among contact lens wearers, 64.3% of the patients either were uncomfortable wearing contact lenses or experienced vision changes "sometimes" or "frequently." CONCLUSION Demodex blepharitis results in a significant negative impact on daily activities, creating a psychosocial and symptomatic burden on patients.

Abstract
PURPOSE The aim of this study was to evaluate the long-term outcomes of lotilaner ophthalmic solution, 0.25%, in the treatment of Demodex blepharitis. METHODS This observational, extension study included patients with Demodex blepharitis (N = 239) who completed the Saturn-1 study and presented for the day 180 visit. All participants were assessed at days 180 and 365 after the initiation of 6-week treatment with the study drug or its vehicle. RESULTS The proportion of patients with 0 to 2 collarettes (grade 0) was significantly higher in the study group (N = 128 patients) than in the control group (N = 111 patients) (39.8% vs. 2.7% at day 180 and 23.5% vs. 2.9% at day 365; P < 0.0001). Similarly, the proportion of patients with ≤10 collarettes (collarette grade 0-1) in the study group was significantly higher than in the control group (70.3% vs. 18.0% at day 180 and 62.6% vs. 21.9% at day 365; P < 0.0001). In the study group, erythema continued to improve even after completion of the 6-week lotilaner treatment. No serious ocular adverse events were observed in the study group, and there was 1 treatment-related ocular adverse event in the study group, which was considered mild. CONCLUSIONS After 6-week treatment with lotilaner ophthalmic solution, 0.25%, for Demodex blepharitis, no long-term concerns were observed during 1 year of follow-up. A high proportion of patients with 0 to 2 collarettes (grade 0) or ≤10 collarettes (collarette grade of 0 or 1) was observed throughout 1 year of follow-up, indicating that the efficacy of lotilaner ophthalmic solution, 0.25%, against Demodex blepharitis may last well after completion of therapy.

Abstract
PURPOSE Ocular demodicosis can cause debilitating ocular surface disease. As ivermectin is effective at reducing Demodex proliferation in rosacea, this study investigated the efficacy of topical ivermectin 1.0% cream in treating ocular demodicosis. METHODS This retrospective single-centre clinical practice chart analysis involved the off-label treatment of patients who had ocular demodicosis with topical ivermectin 1.0 % cream (Soolantra, Galderma Ltd, UK) applied nightly to the lid margins of both eyes for 3 months. Ocular surface health was assessed at baseline when the treatment was prescribed and followed up at 3 and 12 months after baseline. Slit lamp biomicroscopy was used to take digital images of the upper eyelid lashes. Manual image analysis with ImageJ was conducted by a masked assessor to quantify signs of ocular demodicosis including the number of lashes with collarettes, with visible Demodex tails and with follicle pouting. RESULTS Data from a total of 75 patients with ocular demodicosis were analysed for this study (mean age 66.6 ± 13.9 years, 44 female). The numbers of lashes with collarettes (Median [Interquartile range]: 8 [4-13] at baseline to 0 [0-2] at the final visit, p < 0.001) and lashes with follicle pouting (3 [1-5] at baseline to 0 [0-1.8] at the final visit, p < 0.001) decreased with treatment. Any sign of lashes with visible tails was eliminated by the final visit (p < 0.007). Fluorescein staining severity score also improved, particularly from baseline (1 [0-2]) to the second visit (0 [0-1], p < 0.001). CONCLUSIONS The findings of this study show evidence for the efficacy of a 3-month course of topical ivermectin 1.0% cream in treating ocular demodicosis as indicated by reduction in collarettes, follicle pouting and visible Demodex tails. More research is warranted to improve the diagnosis, management and monitoring of this condition which is often overlooked or misdiagnosed.

Abstract
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. Review Manager (Version 5.4.1) software was used to conduct all statistical analyses. RESULTS Four RCTs (947 patients) were included in this study. The overall effect favored the lotilaner group in terms of mean collarette grade upper lid (MD -0.99, 95% CI [-1.26, -0.72]), MCG lower lid (MD -0.57, 95% CI [-1.03, -0.11]), Md (MD -1.13, 95% CI [-1.47, -0.79]), MCR (MD 2.07, 95% CI [2.27, 3.21]), ME (MD 3.46, 95% CI [2.96, 4.04]). EC (RR 3.16, 95% CI [2.18 to 4.59]) and CC (RR 4.17, 95% CI [2.97 to 5.85]). No significant difference between the two groups in terms of AE (RR 1.25, 95% CI [0.75 to 2.06]). However, these findings are limited by significant heterogeneity in some of the reported outcomes. CONCLUSIONS Our findings show that lotilaner might effectively treat Demodex blepharitis. However, further RCTs with larger and more diverse populations are needed to confirm these findings as some outcomes show significant heterogeneity.

A Systematic Review and Meta-Analysis of the Safety and Efficacy of 0.25% Lotilaner Ophthalmic Solution in the Treatment of Demodex Blepharitis. Cureus 2024; 16:e52664. [PMID: 38380217 PMCID: PMC10878406 DOI: 10.7759/cureus.52664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/20/2024] [Indexed: 02/22/2024] Open
Abstract
Demodex blepharitis is marked by an excessive presence of Demodex mites on the eyelids, particularly in the lash follicles. While these microscopic mites are a natural component of the skin microbiota, their overabundance can lead to ocular complications. Symptoms associated with Demodex blepharitis include eyelid itching, inflammation, and ocular irritation. Our objective is to investigate Lotilaner as a potential treatment for Demodex blepharitis, assessing both the safety and efficacy of the ophthalmic formula in managing this disease. We conducted research in Web of Science, PubMed, Cochrane Library, and Scopus up to November 2023. The quality of studies was evaluated using the Cochrane Risk of Bias tool, and it was employed to evaluate the quality of evidence. Our meta-analysis was executed using Review Manager 5.4. We evaluated the safety and efficacy of Lotilaner ophthalmic solution with a concentration of 0.25%. The following outcomes were assessed: clinically meaningful reduction in collarette, collarette cure, composite cure, drop comfort, erythema cure, mite density, and mite eradication. In the case of dichotomous data, we used the risk ratio (RR) with a 95% confidence interval (CI). In our analysis, all included studies, comprising a total of 891 participants, consistently reported clinically meaningful reductions in collarettes. The findings were statistically significant, with Lotilaner demonstrating a substantially higher reduction compared to the vehicle group (RR = 3.09, 95% CI [2.65-3.60]; P-value < 0.0001). Notably, results for Drop Comfort outcomes were nonsignificant, indicating no discernible differences compared to the group that used the vehicle (RR = 1.03, 95% CI [0.98-1.07]; P-value = 0.26). However, both mite density and mite eradication outcomes exhibited significant improvements with Lotilaner in comparison to the vehicle (RR = 2.58, 95% CI [2.25-2.95]; P-value < 0.0001) and (RR = 3.80, 95% CI [2.88-5.01]; P-value < 0.0001). The Lotilaner ophthalmic solution at 0.25% showed superior efficacy over the vehicle in reducing collarettes, achieving complete mite eradication within six weeks, and significantly decreasing erythema in Demodex blepharitis. It demonstrated safety with no reported side effects compared to the vehicle. Direct comparative studies with alternative treatments are recommended for a comprehensive assessment of efficacy and safety.

Abstract
Rosacea is a chronic inflammatory disease with a multifactorial pathogenesis. The wide spectrum of clinical phenotypes, including erythema, telangiectasia, inflammatory papules and pustules, and phyma, demand an individualized approach to treatment. This narrative review offers an updated reference for rosacea management by covering the latest developments in both topical and systemic treatments, including data from newly approved therapies, updates to current treatment modalities and ongoing clinical trials. Although use of benzoyl peroxide as a treatment for rosacea has typically been limited due to irritation, the improved tolerability due to microencapsulation of benzoyl peroxide 5% cream provides a new therapeutic option for patients with rosacea. Minocycline foam and topical ivermectin cream add to our armamentarium of treatment options, particularly for inflammatory papules and pustules. Sarecycline has a narrower spectrum of antibacterial activity, which might reduce the development of antibiotic resistance and disruption of the microbiome compared to other oral antibiotics. Brimonidine gel and oxymetazoline cream provide topical options for redness and flushing. There is emerging evidence about the role of hydroxychloroquine and intradermal botulinum toxin A, which may improve rosacea through their effects on mast cells. The clinical trials pipeline includes agents with a variety of mechanisms, including mast cell stabilization, antimicrobial, anti-inflammatory, and vasoconstrictive effects. However, the clinical pipeline for rosacea appears limited, and there remain important unmet needs for patients with more recalcitrant rosacea or phymatous disease. In addition, there is a need for comparative effectiveness studies to identify the highest value treatment approaches for patients with rosacea.

Abstract
PURPOSE To evaluate the safety and efficacy of lotilaner ophthalmic solution 0.25% compared with vehicle for the treatment of Demodex blepharitis. DESIGN Prospective, randomized, double-masked, vehicle-controlled, multicenter, phase 3 clinical trial. PARTICIPANTS Four hundred twelve patients with Demodex blepharitis were assigned randomly in a 1:1 ratio to receive either lotilaner ophthalmic solution 0.25% (study group) or vehicle without lotilaner (control group). METHODS Patients with Demodex blepharitis treated at 21 United States clinical sites were assigned either to the study group (n = 203) to receive lotilaner ophthalmic solution 0.25% or to the control group (n = 209) to receive vehicle without lotilaner bilaterally twice daily for 6 weeks. Collarettes and erythema were graded for each eyelid at screening and at all visits after baseline. At screening and on days 15, 22, and 43, 4 or more eyelashes were epilated from each eye, and the number of Demodex mites present on the lashes was counted with a microscope. Mite density was calculated as the number of mites per lash. MAIN OUTCOME MEASURES Outcome measures included collarette cure (collarette grade 0), clinically meaningful collarette reduction to 10 collarettes or fewer (grade 0 or 1), mite eradication (0 mites/lash), erythema cure (grade 0), composite cure (grade 0 for collarettes as well as erythema), compliance with the drop regimen, drop comfort, and adverse events. RESULTS At day 43, the study group achieved a statistically significant (P < 0.0001) higher proportion of patients with collarette cure (56.0% vs. 12.5%), clinically meaningful collarette reduction to 10 collarettes or fewer (89.1% vs. 33.0%), mite eradication (51.8% vs. 14.6%), erythema cure (31.1% vs. 9.0%), and composite cure (19.2% vs. 4.0%) than the control group. High compliance with the drop regimen (mean ± standard deviation, 98.7 ± 5.3%) in the study group was observed, and 90.7% of patients found the drops to be neutral to very comfortable. CONCLUSIONS Twice-daily treatment with lotilaner ophthalmic solution 0.25% for 6 weeks generally was safe and well tolerated and met the primary end point and all secondary end points for the treatment of Demodex blepharitis compared with vehicle control.

Delphi Panel Consensus Regarding Current Clinical Practice Management Options for Demodex blepharitis. Clin Ophthalmol 2023; 17:667-679. [PMID: 36875531 PMCID: PMC9983333 DOI: 10.2147/opth.s399989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 02/13/2023] [Indexed: 03/02/2023] Open
Abstract
Purpose To obtain consensus on Demodex blepharitis (DB) treatment using a modified Delphi panel process. Methods Literature search identified gaps in knowledge surrounding treatment of DB. Twelve ocular surface disease experts comprised the Demodex Expert Panel on Treatment and Eyelid Health (DEPTH). They completed a live roundtable discussion in addition to 3 surveys consisting of scaled, open-ended, true/false, and multiple-choice questions pertaining to the treatment of DB. Consensus for scaled questions using a 1 to 9 Likert scale was predefined as median scores of 7-9 and 1-3. For other question types, consensus was achieved when 8 of 12 panelists agreed. Results The experts agreed that an effective therapeutic agent for treatment of DB would likely decrease the necessity of mechanical intervention, such as lid scrubs or blepharoexfoliation (Median = 8.5; Range 2-9). When treating DB, panelists believed that collarettes serve as a surrogate for mites, and that eliminating or reducing collarettes should be the main clinical goal of treatment (Median = 8; Range 7-9). The panelists would treat patients with at least 10 collarettes, regardless of other signs or symptoms and agreed that DB can be cured, but there is always the possibility for a reinfestation (n = 12). There was also consensus that collarettes, and therefore mites, are the primary treatment target and the way by which clinicians can monitor patient response to therapy (Median = 8; Range 7-9). Conclusion Expert panelists achieved consensus on key facets of DB treatment. Specifically, there was consensus that collarettes are pathognomonic for DB, that DB patients with >10 collarettes should be treated even in the absence of symptoms, and that treatment efficacy can be tracked by collarette resolution. By increasing awareness about DB, understanding the goals of and monitoring treatment efficacy, patients will receive better care and, ultimately, better clinical outcomes.
