How Long to Continue Eyelid Hygiene to Treat Meibomian Gland Dysfunction.

ABSTRACT: To determine the efficacy duration of eyelid hygiene for meibomian gland dysfunction (MGD) treatment, a total of 1015 participants with primary MGD, followed for at least 6 months, were enrolled. The participants were classified into the eyelid hygiene group and the control group. The participants who had stopped eyelid hygiene at any point in the observation period after the initial 2 months were classified into the withdrawal group. Analysis was conducted with a generalized linear mixed model. Treatment group, age, sex, ocular surface inflammation, anti-inflammatory treatments, and baseline MGD subtype were considered as fixed effects, and the individual factor was considered as a random effect. The MGD stage decreased significantly for the observational period in the eyelid hygiene group (p < 0.001). Approximately 40.1% of the participants continuously maintained eyelid hygiene throughout the observational period. The MGD stage in the eyelid hygiene group continued to decrease for 6 months and was maintained thereafter. After 4 months of stopping eyelid hygiene, the MGD stage in the withdrawal group was worse than in the eyelid hygiene group (p < 0.001) and similar to that in the control group (p = 0.762). Maintaining eyelid hygiene was significantly effective in MGD treatment. Efficacy increased with treatment for 6 months, and the efficacy duration was maintained for 4 months even after stopping eyelid hygiene. Therefore, we recommend that patients with MGD maintain eyelid hygiene, and compliance should be checked continuously.

Project description:AimThe main treatment for meibomian gland dysfunction (MGD), a major cause of dry eye, is eyelid warming. Lack of compliance is the main reason for treatment failure. This has led to the development of eyelid-warming devices that are safe, effective and convenient. To obtain robust evidence demonstrating their efficacy, the authors conducted a 3-arm randomized clinical study.MethodsThe authors conducted a 3-month assessor-blinded, randomized, controlled trial of patients from the Singapore National Eye Centre experiencing at least one of eight dry eye symptoms 'often' or 'all the time'. Patients who wore contact lenses, had an active infection or known diagnosis of thyroid dysfunction and rheumatoid arthritis were excluded from the study. MGD participants were randomly assigned to warm towel (n = 25), EyeGiene(®) (Eyedetec Medical Inc., Danville, CA, USA) (n = 25) and Blephasteam(®) (Spectrum Thea Pharmaceuticals LTD, Macclesfield, UK) (n = 25) treatments. The primary efficacy and safety outcomes included the proportions of participants with improved symptoms and changes in best corrected visual acuity (BCVA), respectively. Other outcomes included tear break up time (TBUT), Schirmer test, corneal fluorescein dye staining and number of visibly occluded meibomian gland (MG) orifices.ResultsThe study population was 53.5 ± 11.1 years old and predominantly Chinese. For severity of symptom after 3 months of treatment, 78.3% Blephasteam(®) participants reported improvement compared to 45.5% warm towel participants (p = 0.023). The corresponding proportions for improvement in the frequency of symptoms were 82.6% and 50.0%, respectively (p = 0.020). The proportions of improvement of symptoms in EyeGiene(®) patients were not significantly different from warm towel intervention. At 1 month of treatment, the crude odds ratio of improvement of severity of irritation for Blephasteam(®) compared to control was 3.0 (95% CI 0.88-10.18). However, the odds ratio adjusted by age was 5.67 (1.30-24.66). The lid-warming treatments did not significantly change the TBUT, Schirmer test results or number of visibly occluded MGs in the study period. All treatment modalities did not worsen BCVA after 3 months.ConclusionBlephasteam(®) is more effective than warm towel for MGD treatment, with warm towel and EyeGiene(®) being comparable effective. Older age might predict for treatment efficacy. All studied therapies were safe for visual acuity (VA) for 3 months of treatment.

Project description:AimsThis study aimed to evaluate the efficacy and safety of bevacizumab eye drops compared with those of an intra-meibomian gland (MG) injection of bevacizumab when performed in conjunction with standard lid hygiene in patients with meibomian gland dysfunction (MGD)-associated posterior blepharitis.MethodsThis prospective, open-label, observer-blinded randomized controlled trial included 60 eyes of 30 patients with MGD-associated posterior blepharitis who exhibited lid margin telangiectasia, treated at the Chula Refractive Surgery Center of King Chulalongkorn Memorial Hospital. Patients were randomized to receive lid hygiene plus 0.05% bevacizumab eye drops or a single intra-MG injection of 2.5% bevacizumab. All patients were instructed to perform routine lid hygiene care as demonstrated in an instructional video. Primary outcomes included telangiectasia grading and the lid margin neovascularized area (LMNA). Secondary outcomes included the Ocular Surface Disease Index (OSDI) score, corneal staining, meibum quality, meiboscore, conjunctival redness, fluorescein break-up time (FBUT), lipid layer thickness, treatment compliance, and adverse events. All parameters were evaluated before and 3 months after treatment.ResultsAfter treatment, there were no significant differences in telangiectasia grade and LMNA between groups (mean difference, -0.14, 95% CI -0.42 to 0.15, p = 0.338, -0.1, 95% CI -1.1 to 0.8, p = 0.761, respectively); however, the injection group exhibited significant improvements in both telangiectasia grade and LMNA, while, in the eye drop group, only telangiectasia grade showed a significant improvement relative to baseline. The injection group also exhibited significant improvements in corneal staining (mean difference, -0.78, 95% CI -1.29 to -0.27, p = 0.003), meiboscores (mean difference, -0.37, 95% CI -0.52 to -0.21, p <0.001), and FBUT (mean difference, 1.25, 95% CI 0.21-2.29, p = 0.019) compared to the eye drop group. OSDI scores, corneal staining, meibum quality, meiboscores, and conjunctival redness significantly improved relative to baseline in both groups. No local and systemic adverse event was observed at month 3 in both groups.ConclusionWhen performed with regular lid hygiene, intra-MG injection and topical application of bevacizumab are safe and effective for improving lid margin telangiectasia and the signs and symptoms of MGD-associated posterior blepharitis. This therapy may represent an alternative or adjunctive treatment for patients with MGD-associated posterior blepharitis.
