TearCare for the Treatment of Meibomian Gland Dysfunction in Adult Patients With Dry Eye Disease: A Masked Randomized Controlled Trial.

PURPOSE: The aim of this study was to demonstrate the safety and effectiveness of a single TearCare procedure compared with a single LipiFlow procedure in treatment of the dry eye disease associated with meibomian gland dysfunction. METHODS: In a multicenter, masked, randomized controlled trial, 135 subjects received a single TearCare (TC) treatment (n = 67) or a single LipiFlow (LF) treatment (n = 68) at baseline and were followed up for 1 month posttreatment. Tear film breakup time, meibomian gland function, and corneal and conjunctival staining scores were assessed as dry eye signs at baseline, 2 weeks, and 1 month; dry eye symptoms were assessed using the Ocular Surface Disease Index, Symptom Assessment in Dry Eye, and eye dryness questionnaires at baseline and 1 month. RESULTS: At 1 month posttreatment, both groups demonstrated significant improvements (P < 0.0001) in mean tear film breakup time and meibomian gland secretion score to 3.0 ± 4.4 and 11.2 ± 11.1 in the TC group and 2.6 ± 3.3 and 11.0 ± 10.4 in the LF group, respectively. The mean eye dryness, Symptom Assessment in Dry Eye, and Ocular Surface Disease Index scores were significantly reduced (P < 0.0001) by 35.4 ± 34.1, 38.2 ± 31.0, and 27.9 ± 20.5 in the TC group and 34.9 ± 26.9, 38.0 ± 25.9, and 23.4 ± 17.7 in the LF group, respectively. There were no statistically significant differences for any result between the groups. However, the TC group demonstrated numerically greater improvements consistently in all signs and symptoms. Device-related ocular adverse events were reported in 3 patients in the TC group (superficial punctate keratitis, chalazion, and blepharitis) and 4 patients in the LF group (blepharitis, 2 cases of foreign body sensation, and severe eye dryness). CONCLUSIONS: A single TearCare treatment significantly alleviates the signs and symptoms of dry eye disease in patients with meibomian gland dysfunction and is equivalent in its safety and effectiveness profile to LipiFlow treatment as shown in this 1-month follow-up study.

Preoperative Management of MGD with Vectored Thermal Pulsation before Cataract Surgery: A Prospective, Controlled Clinical Trial.

Purpose: To investigate the efficacy of preoperative monocular treatment in elderly cataract patients with Meibomian Gland Dysfunction (MGD) utilizing vectored thermal pulsation treatment.Materials and Methods: This study was a prospective, examiner-masked contralateral eye clinical trial. Patients previously diagnosed with MGD undergoing uncomplicated cataract surgery in two eyes were enrolled. The eye perceived by the patient to be more symptomatic of MGD received a 12 min vectored thermal pulsation treatment using the LipiFlow Thermal Pulsation System, and was referred to as the LipiFlow-surgery eye. The contralateral eye then served as the nonLipiFlow-surgery eye. Patients with MGD not undergoing cataract surgery were enrolled as the control group. Within the control group, the eye that received LipiFlow treatment was considered the LipiFlow-nonsurgery eye, while the contralateral eye served as the nonLipiFlow-nonsurgery eye. All patients were examined before treatment and at one-week, one-month, and three-month intervals after treatment. Clinical parameters included dry eye symptoms, average lipid layer thickness (LLT-ave), tear breakup time (TBUT), corneal staining, Schirmer I tests, Meibomian glands yielding liquid secretion (MGYLS), and meibomian gland dropout.Results: A total of 32 patients (64 eyes) were examined during the three-month follow-up. There was a significant reduction in dry eye symptoms in non-surgery patients with monocular treatment of MGD, while no change in surgery patients was observed. Significant improvement of MGYLS in LipiFlow-surgery and LipiFlow-nonsurgery eyes during the follow-up time (p < .001) was reported, while no difference was observed in nonLipiFlow-surgery and nonLipiFlow-nonsurgery eyes. A statistically significant difference was seen in TBUT between LipiFlow-surgery and nonLipiFlow-surgery eyes at one-week and one-month intervals (p = .019 and 0.019, respectively). Differences in other clinical parameters were not statistically significant.Conclusions: Our findings suggest that although subjective symptoms were not alleviated, a single application of LipiFlow treatment before cataract surgery is effective in alleviating blockage of meibomian glands and preventing the decline of TBUT after cataract surgery.

Efficacy of Topical Ivermectin for the Treatment of Cutaneous and Ocular Rosacea.

Purpose: To investigate the efficacy of once-daily topical treatment of ocular and cutaneous rosacea with ivermectin 1% cream (Soolantra®, Galderma).Methods: Ten patients with rosacea were evaluated in a retrospective monocentric pilot study. Subjective symptoms (measured with the Ocular Surface Disease Index), skin findings, and ocular changes (blepharitis with telangiectasia and meibomian gland dysfunction, conjunctival redness, tear breakup time (TBUT), and fluorescein staining of the cornea) were evaluated. The follow-up was 8 months (range: 5-12 months).Results: The OSDI score decreased in the 8th week of treatment (38.5 ± 21.7, P = .004). After 16 weeks, blepharitis (P = .004), and conjunctival redness (P = .008) had strongly improved, and grade 1 was seen in all patients until the end of follow-up. Fluorescein staining of the cornea (P = .001) and TBUT (P = .016) showed significant improvement until the last follow-up visit. No side effects were observed. Conclusion: Topical ivermectin cream 1% given daily is an effective and safe therapy against rosacea.

Intense Pulsed Light for Meibomian Gland Disease: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the literature on the efficacy of intense pulsed light (IPL) on the eyelids in the management of meibomian gland disease (MGD) and meibomian gland-related ocular surface disease. METHODS: A literature search was last conducted on May 15, 2019, in the PubMed and Cochrane Library databases for English-language original research that assessed the effect of IPL on MGD in adult patients. Thirty-three articles were identified, and 12 studies were determined to be relevant to the criteria outlined for assessment. The panel methodologist (V.K.A.) assigned a level of evidence rating to each study; 4 studies were rated level II, and 8 studies were rated level III. Five studies had potential conflicts of interest and design limitations that affected interpretation of results. RESULTS: All studies documented improvement in clinically meaningful metrics, including tear breakup time (TBUT), corneal staining and eyelid margin measurements, meibum quality, meibomian gland expressability, ocular surface disease index (OSDI), and standard patient evaluation of eye dryness (SPEED) questionnaire scores. Side effects were relatively uncommon but included discomfort, cutaneous erythema, blistering, eyelash loss, and floaters; these were uniformly self-limited. CONCLUSIONS: Although methodological limitations and potential conflicts of interest in some studies raised concern, the existing body of literature demonstrates improvements in the signs and symptoms of MGD after IPL therapy.

Ocular surface changes in the treatment of rosacea: comparison between low-dose oral isotretinoin and doxycycline / Alterações da superfície ocular no tratamento da Rosácea: comparação entre isotretinoína oral em baixa dosagem e doxiciclina

ABSTRACT Purpose: To compare the impact of ocular changes between systemic treatment with doxycycline and low-dose oral isotretinoin in patients with moderate-to-severe papulopustular rosacea. Methods: Patients were randomized to receive either isotretinoin 0.3-0.4 mg/kg (group A) or doxycycline 100 mg/day (group B) for 16 weeks. Ocular symptoms were searched and evaluated, including best-corrected visual acuity (BCVA), Schirmer test, breakup time, rose bengal staining score, and meibomian gland dysfunction grading. The patients were retested at the end of treatment. Results: The present study included 39 patients (30 females and 9 males). Best-corrected visual acuity was > 20/30 in >90% of patients in both groups and did not change after treatment. After treatment, improvement in ocular symptoms and meibomian gland dysfunction was more pronounced in group B (p<0.05); the other parameters did not reach statistical significance. Conclusion: Doxycycline improved meibomian gland dysfunction, ocular symptoms, and ocular surface in patients with rosacea. Even though some patients experienced worsening meibomian gland dysfunction and symptoms, no subject experienced any serious complications after administration of low-dose isotretinoin.

RESUMO Objetivos: Comparar o impacto das alterações oculares entre o tratamento sistêmico de doxiciclina e isotretinoína em baixa dosagem em pacientes com rosácea papulopustulosa moderada a grave. Métodos: Os pacientes form randomizados para receber isotretinoína 0,3 a 0,4 mg/kg (grupo A) ou doxiciclina 100mg/dia (grupo B) por 16 semanas. Os sintomas oculares foram pesquisados e avaliados, incluindo melhor acuidade visual corrigida, teste de Schirmer, tempo de ruptura do filme lacrimal, coloração de rosa bengala e graduação da disfunção de glândula de Meibomius. Os pacientes foram novamente testados no final do tratamento. Resultados: O presente estudo incluiu 39 pacientes (30 mulheres e 9 homens). A melhor acuidade visual corrigida foi >20/30 em >90% dos pacientes em ambos os grupos e não se alterou após o tratamento. A melhora dos sintomas oculares e da disfunção de glândula de Meibomius foi mais pronunciada no grupo B (p<0,05) após o tratamento; as demais variáveis não atingiram significância estatística. Conclusão: A doxiciclina melhorou a disfunção de glândula de Meibomius, os sintomas oculares e a superfície ocular de pa cientes com rosácea. Mesmo que alguns pacientes tenham piorado a disfunção e os sintomas da glândula de Meibomius, nenhum indivíduo apresentou complicações graves após a admi nistração de baixas doses de isotretinoína.

Intense regulated pulse light for the meibomian gland dysfunction.

PURPOSE: To assess the effect of intense regulated pulse light (E-Eye; E-Swin, France) on the treatment of meibomian gland dysfunction. SETTING: Health Sciences University, Ankara Numune Training and Research Hospital, Department of Ophthalmology. METHODS: A total of 26 patients underwent intense pulsed light treatment (E-Eye; E-Swin), with homogeneously sequenced five light pulses delivered to one eye at 1, 15, and 45 days following baseline evaluation. At each visit, subjective clinical parameters (ocular surface disease index questionnaire and standard patient evaluation of eye dryness questionnaire) and objective clinical parameters (Schirmer I test scores, tear break-up times, Oxford grading, lid margin abnormality score, secretion quality and expressibility degree) were recorded. The subjective and objective parameters at Days 15 and 45 were compared with baseline values. RESULTS: Patients underwent three sessions of intense pulsed light treatment. Schirmer test and tear break-up time improved significantly from baseline to Day (D) 45 (8.53 ± 4.31 mm vs 12.6 ± 3.14 mm, 4.53 ± 1.33 sn vs 11.07 ± 2.87 sn, p = 0.003 and p < 0.001). Ocular surface disease index and standard patient evaluation of eye dryness scores improved from baseline to D15 and baseline to D45 (all with p < 0.05). All the subjects reported reduced symptoms by D45. There were no cases of adverse ocular effects. There was no significant change in Oxford grading, lid margin abnormality score, secretion quality, and expressibility degree. CONCLUSIONS: Intense regulated pulse light seems a safe treatment procedure for meibomian gland dysfunction, improving tear film quality and reducing symptoms of dry eye.

The Efficacy of Warm Compresses in the Treatment of Meibomian Gland Dysfunction and Demodex Folliculorum Blepharitis.

Purpose: To investigate and compare the effect of warm compresses on meibomian gland dysfunction and Demodex folliculorum blepharitis.Methods: Forty-two subjects (13 males, 29 females; mean age of 56.45 years) enrolled and completed the two-month warm compress treatment study. Three warm compress therapies were compared: Warm face cloth, MGDRx EyeBag® and OPTASETM Moist Heat Mask. Subjects attended for four visits: baseline, two weeks, four weeks, and eight weeks. Subjective symptoms, osmolarity, non-invasive tear break-up time, ocular surface staining, Schirmer I test, meibum expressibility and clarity, and eyelash manipulation and epilation to assess for the presence of Demodex folliculorum, were measured at each visit.Results: Meibomian gland dysfunction, based on a composite score of meibum quality and expressibility, reduced significantly with the MGDRx EyeBag® and the OPTASETM Moist Heat Mask (p < .05). There was no significant difference in efficacy for treating meibomian gland dysfunction between the two devices (p = .29). No improvement in meibomian gland dysfunction was detected with the warm face cloth. Only the OPTASETM Moist Heat Mask significantly reduced the quantity of Demodex folliculorum over eight-weeks of treatment (p = .036, only baseline to week eight significant p = .008). Symptoms and ocular surface staining improved significantly in all three groups (p < .05). There was no significant change observed in osmolarity, non-invasive tear break-up time or Schirmer I test within each group (p > .05, respectively).Conclusion: The MGDRx EyeBag® and the OPTASETM Moist Heat Mask exhibited superior efficacy in treating signs and symptoms of meibomian gland dysfunction, compared to the use of a warm face cloth, over the eight-week period. The OPTASETM Moist Heat Mask demonstrated dual therapeutic abilities, treating both meibomian gland dysfunction and Demodex folliculorum blepharitis. Repeated application of heat for the treatment of meibomian gland dysfunction may continue to present a good home-remedy option for patients.

Randomised trial of the clinical utility of an eyelid massage device for the management of meibomian gland dysfunction.

PURPOSE: To compare the single application and two week treatment effects of device-applied (Eyepeace) and manually-applied eyelid massage techniques, as an adjunct to warm compress therapy, on ocular surface and tear film parameters. METHODS: Twenty participants (11 females, 9 males; mean age, 27 ±â€¯11 years) with dry eye symptoms were recruited in a two week, investigator-masked, randomised, contralateral-eye trial. Following 10 min of warm compress therapy application (MGDRx EyeBag®) on both eyes, eyelid massage therapy was applied to one eye (randomised) by device, and to the fellow eye by manual eyelid massage, once daily for 14 days. Ocular surface and tear film measurements were conducted at baseline, and 15 min post-application by a clinician, then again after 14 days of self-administered daily treatment at home. RESULTS: Baseline clinical measurements did not differ between the treatment groups (all p > 0.05). Following two weeks of treatment, tear film lipid layer grade improved significantly with device massage (p = 0.008), and was marginally greater than manual massage by less than 1 grade (p = 0.03). Although immediate post-treatment improvements in tear film stability were observed in both groups (both p < 0.05), no significant long-term cumulative effects or inter-treatment differences in stability measures were detected (all p > 0.05). Visual acuity, tear meniscus height, conjunctival hyperaemia, ocular surface staining, and meibomian gland dropout did not change during the treatment period (all p > 0.05). CONCLUSIONS: Two weeks of treatment with the eyelid massage device, as an adjunct to warm compress therapy, effected marginally greater improvements in tear film lipid layer thickness than the conventional manual technique, which were statistically but not clinically significant. Future parallel group trials with longer treatment periods and a greater range of disease severity are required.

Effectiveness of pharmaceutical interventions for meibomian gland dysfunction: An evidence-based review of clinical trials.

Meibomian gland dysfunction is one of the most common ocular disorders encountered by ophthalmologists and is the leading cause of evaporative dry eye. The disease causes significant morbidity in the population such that patients seek treatment. Multiple clinical studies on pharmacological and mechanical interventions for the treatment of meibomian gland dysfunction have been evaluated. However, there is limited comparative clinical evidence for the effectiveness of these interventions. This review paper aims to report the clinical evidence for pharmaceutical interventions for meibomian gland dysfunction in order to guide clinicians in the management of the disease.
