Min JS, Jun I, Kim TI, Arita R, Seo KY. Comparison of Intense Pulsed Light Treatments including Upper Lid or Lateral Canthus in Patients of Meibomian Gland Dysfunction. J Clin Med 2024; 13:3581. [PMID: 38930110 PMCID: PMC11204452 DOI: 10.3390/jcm13123581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 06/10/2024] [Accepted: 06/13/2024] [Indexed: 06/28/2024] Open
Abstract
Background: To determine the differences in the effects of intense pulsed light (IPL) treatment when including the upper and lower lid or lateral canthus area in patients with meibomian gland dysfunction (MGD). Methods: Patients who underwent three IPL treatment sessions at 3-week intervals were divided into three groups according to the treatment sites: group A, lower lid; group B, upper and lower lids; and group C, lower lid and lateral canthal area. Before and after the IPL treatment sessions, we obtained the lid abnormality score (LAS), meibum expressibility (ME), meibum quality (MQ), lipid layer thickness (LLT), type I Schirmer test (ST), tear break-up time (TBUT) test, corneal fluorescein staining scores (CFSs), and Ocular Surface Disease Index (OSDI). Results: IPL treatment significantly improved LASs, ME, MQ, TBUT, CFS, and OSDI values in all groups. Differences in LAS values before and after IPL treatment were significantly greater in groups B and C than those in group A. Conclusions: IPL treatment encompassing the upper lid and lateral canthus together with the lower lid elicited additional improvement in patients with MGD. The additional effect on treating the lateral canthus was similar to the effect observed on the additional treatment of the upper lid.

Indian J Ophthalmol 2024; 72:S183-S190. [PMID: 38146980 DOI: 10.4103/ijo.ijo_671_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: 03/08/2023] [Accepted: 10/03/2023] [Indexed: 12/27/2023] Open
Abstract
This review explored intense pulsed light (IPL) as an alternative treatment for dry eye disease (DED) symptom relief by correcting tear-film homeostasis. A systematic search was performed in March 2022 on five databases (Medline, Embase, SCOPUS, ProQuest, and EBSCO). Studies were extracted for the following outcomes of interest: standard patient evaluation of eye dryness questionnaire (SPEED), ocular surface disease index (OSDI), tear break-up time (TBUT), and corneal fluorescein staining (CFS). All studies published up to March 2022 were reviewed. Cochrane risk of bias tool (RoB 2) was used to screen studies for risk of bias where appropriate. A meta-analysis was done to quantify any reported quantitative data. Thirteen studies were included in this study. A total of 931 individuals and 1454 numbers of eyes were reviewed in this meta-analysis. Among studies that explored and reported the effect of IPL in individuals with DED, TBUT and OSDI improved significantly post intervention, with a standardized mean difference (SMD) of 1.02 [95% CI 0.41-1.64] and 0.28 [95% CI 0.04-0.52], respectively. CFS and SPEED scores, however, showed no statistically significant difference, with an SMD of 0.22 [95% CI -0.19 to 0.64] and 0.28 [95% CI -0.11 to 0.66], respectively. In conclusion, current evidence indicates IPL as a possible adjunctive treatment in individuals with DED in an otherwise limited treatment option. Further studies through more extensive trials are needed to validate this finding and elucidate its mechanism.

Abstract
BACKGROUND To evaluate changes in objective optical quality following intense pulsed light (IPL) treatment combined with meibomian gland (MG) expression (MGX) in patients with MG dysfunction (MGD). METHODS This retrospective cross-sectional study included MGD-related dry eye disease (DED) patients who received IPL treatment between March and December 2021 at Kim's Eye Hospital, Seoul, Republic of Korea. Each patient underwent four sessions of IPL treatment using Lumenis M22 (Lumenis Ltd., Yokneam, Israel) and MGX at three-week intervals. RESULTS This study included 90 eyes from 45 patients with MGD. The mean age was 52.3 ± 16.1 years (range, 20-75 years), and 53.3% (24/45) of patients were female. Compared with the baseline, all clinical symptoms and signs significantly improved after IPL treatment combined with MGX. All optical quality parameters obtained with an optical quality analysis system (OQAS: Visiometrics, Castelldefels, Spain) have improved significantly over the baseline (p < 0.001). CONCLUSIONS In patients with MGD, IPL treatment combined with MGX improved the objective optical quality and clinical signs and symptoms of DED.

Abstract
Our study compared treatment efficacy between cut-off and notch filters in intense pulsed light (IPL) therapy for meibomian gland dysfunction (MGD) through a prospective, randomized paired-eye trial. Additionally, the efficacy of IPL treatment alone was investigated by restricting other conventional treatments. One eye was randomly selected for an acne filter and the other for a 590-nm filter. Identical four regimens of IPL treatments were administered. The tear break-up time (TBUT), Oxford scale, Sjögren's International Clinical Collaborative Alliance (SICCA) staining score, tear matrix metalloproteinase-9 (MMP-9) expression, tear osmolarity, and Ocular Surface Disease Index (OSDI) questionnaires were evaluated before and after IPL. Meibomian gland (MG) parameters were measured. When combining the results from both filters, the TBUT, SICCA staining score, OSDI score, and upper and lower lid meibum expressibility were improved after IPL. No significant differences were found between the two filters in the TBUT, Oxford scale, SICCA staining score, MMP-9 expression, tear osmolarity, and MG parameters. Although not significant, the acne filter showed better treatment efficacy than that in the 590-nm filter. IPL alone is efficacious in terms of ocular surface parameters, MG function, and subjective symptoms. Regarding filter selection, both acne and 590-nm filters are promising options for MGD treatment.

Abstract
Objective: To evaluate relevant clinical outcomes and conclude possible mechanisms of intense pulsed light (IPL) in eyelid inflammation. Background: IPL devices were primarily applied in cutaneous vascular malformations and have been used in ocular diseases for about 20 years, mostly including meibomian gland dysfunction (MGD), blepharitis, and ocular rosacea. Recent findings: Seventy-two original clinical researches were included, 57 for MGD, 4 for blepharitis or blepharitis-related keratoconjunctivitis, and 11 for rosacea. Dry eye symptoms, (tear) break-up time (BUT), and meibomian structure and/or functions were improved in most patients, but production of reactive oxygen species is an important link in the photobiomodulation mediated by IPL, which can influence numerous signal pathways to achieve anti-inflammatory, anti-infective, and prodifferentiation effects. Conclusions: The evidence suggests that IPL is an effective therapeutic tool for most patients with MGD, but more clinical evidence is needed for other indications.

Abstract
OBJECTIVES To investigate awareness, prevalence, and knowledge of dry eye among Internet professionals in China. METHODS A cross-sectional study was conducted among 1,265 randomly selected Internet professionals aged ≥18 years. A self-administered questionnaire was used to assess dry eye awareness, dry eye symptoms, and knowledge about dry eye risk factors. Data on demographics and complete medical history were also collected. The primary outcome was the rate of dry eye awareness determined by the answer to the question "Have you seen or heard anything about dry eye recently?" RESULTS Of the 1,265 included individuals aged 20 to 49 years, 519 (41.0%) were women. 54.4% (688 of 1,265) of participants had seen or heard something about dry eye recently and most had obtained information through Internet. 50.8% (643 of 1,265) of participants were identified as subjects with symptoms of dry eye. Dry eye awareness was greater in contact lens wearers (odds ratio [OR], 6.49; 95% confidence interval [CI], 3.70-11.38; P <0.001), those with a refractive surgical history (OR, 5.09; 95% CI, 2.34-11.08; P <0.001), relatives and/or friends of ophthalmologists (OR, 2.76; 95% CI, 1.39-5.49; P =0.004), those with symptoms of dry eye (OR, 1.87; 95% CI, 1.47-2.38; P <0.001) and female subjects (OR, 1.44; 95% CI, 1.13-1.86; P =0.004). Knowledge of nonmodifiable and modifiable risk factors for dry eye was poor in substantial numbers of the participants. CONCLUSIONS The level of dry eye awareness and knowledge of its risk factors is suboptimal in Internet professionals, although the Internet professionals are at high risk of the disease.

Abstract
PURPOSE We investigated the subjective and objective outcome after intense pulsed light (IPL) treatment and meibomian gland expression on the upper and lower eyelids compared with those after IPL treatment on the lower eyelid alone in patients with moderate-to-severe meibomian gland dysfunction (MGD). METHODS Patients who underwent four IPL treatment sessions with meibomian gland expression were divided into upper and lower treatment group and conventional treatment group treated with lower eyelid alone. All patients underwent an ophthalmologic examination and answered a symptom questionnaire before the first treatment and 1 month after the last treatment. An ophthalmologic examination included tear break-up time (TBUT), fluorescein staining score, Schirmer's test, matrix metalloproteinase-9 (MMP-9), meibum grade, color, consistency, and lid margin telangiectasia. Additionally, visual acuity and adverse effects were checked on every visit. RESULTS Of 115 patients, 75 in the upper and lower treatment group and 40 in the conventional treatment group were included. TBUT, fluorescein staining score, subjective symptom, and meibum grade were significantly improved in both groups. Additionally, meibum color and consistency of upper and lower eyelids significantly decreased post-treatment in both groups. The lid margin telangiectasia of the upper and lower eyelids significantly decreased post-treatment in the upper and lower treatment group. MMP-9 positivity and grading scores significantly decreased post-treatment in both groups, and no severe adverse effects occurred during the follow-up period. CONCLUSION Additional IPL treatment on the upper eyelid using a protective device was proven safe and provided an additive improvement in treating moderate-to-severe MGD.

Abstract
To compare the effect of intense pulsed light (IPL) therapy and conventional treatments in meibomian gland dysfunction (MGD)-related dry eye disease (DED). A literature search was conducted in PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, and China Biology Medicine (CBM) up to January 2022. Randomized controlled trials (RCTs) were included. Mean differences (MDs) and their 95% confidence intervals (CIs) were calculated. A meta-analysis concerning changes in tear break-up time (BUT), changes in Ocular Surface Disease Index (OSDI) scores, changes in non-invasively measured tear break-up time (NIBUT), changes in corneal and conjunctival fluorescein staining (CFS) scores, and changes in Standard Patient Evaluation of Eye Dryness (SPEED) scores was carried out. The initial search identified a total of 1842 records in the databases, and 11 studies were included in the final analysis. Compared to conventional therapies, IPL therapy was associated with significantly reduced OSDI (MD, - 7.49; 95% CI, - 12.47 to - 2.5) and SPEED (MD, - 3.28; 95% CI, - 5.64 to - 0.93) scores, while BUT (MD, 1.94; 95% CI, 1.19 ~ 2.69) and NIBUT (MD, 2.55; 95% CI, 1.07 ~ 4.04) significantly increased. No significant difference was found in the change in CFS between the two groups. Both IPL treatment and traditional treatments are effective in the treatment of MGD-related DED. IPL application seems to be superior to traditional treatments.

Abstract
We aimed to investigate the prognostic factors for, and treatment efficacy of, intense pulsed light (IPL) treatment with a vascular filter in patients with moderate or severe meibomian gland dysfunction (MGD). In this retrospective observational study, 58 moderate or severe MGD patients who underwent IPL treatment with a vascular filter were enrolled. IPL treatment was administered to the upper and lower eyelids four times at two-week intervals. At baseline, and four weeks after IPL, we evaluated the matrix metalloproteinase (MMP)-9 expression levels, tear break-up times (TBUT), ocular surface staining scores, lid margin telangiectasias, and meibomian gland characteristics. The subjective symptoms and adverse effects were reviewed and recorded. Regression analyses were performed to explore the prognostic factors affecting clinical outcomes. IPL treatment using a vascular filter led to improvements in the TBUT, ocular surface staining score, meibomian gland grade, meibum quality and consistency, lid margin telangiectasia, and symptom score (all p < 0.001). Furthermore, the positivity rate (90.2% to 70.6%, p = 0.013) and expression levels (1.92 ± 1.18 to 1.24 ± 1.18, p < 0.001) of tear MMP-9 improved after the IPL treatment. In multivariate logistic regression analysis, a young age (odds ratio = 0.867, p = 0.007) and a toothpaste-like consistency in the upper lid (odds ratio = 8.449, p = 0.046) were associated with improvements in the meibomian gland grade. No adverse effects were detected. IPL with a vascular filter is a safe and effective treatment for moderate and severe MGD. Age and the meibum consistency in the upper lid are important prognostic factors.

Abstract
Purpose We investigated the change in skin temperature of treated areas during intense pulsed light (IPL) treatment in patients who have meibomian gland dysfunction (MGD) to determine whether there is superficial telangiectatic blood vessel ablation. Methods The medical records of 90 patients (90 eyes) with MGD who underwent IPL treatment were reviewed. The patients had undergone IPL treatment four times every 4 weeks. Ocular Surface Disease Index (OSDI) scores, dry eye (DE), and MGD parameters were obtained before the first and after the fourth IPL treatments. The skin temperatures of the upper and lower lids were measured before every IPL treatment. Results The skin temperatures of the lower lids were 31.89 ± 0.72°C at the first IPL (IPL#1), 30.89 ± 0.63°C at the second IPL (IPL#2), 30.14 ± 0.95°C at the third IPL (IPL#3), and 29.74 ± 0.87°C at the fourth IPL (IPL#4) treatments. The skin temperatures of upper lids were 32.01 ± 0.69°C at IPL#1, 31.13 ± 0.75°C at IPL#2, 30.34 ± 1.07°C at IPL#3, and 29.91 ± 0.76°C at IPL#4. The skin temperature of the upper and lower lids significantly decreased with every IPL treatment. Schirmer 1 test (ST) result was 12.97 ± 10.22 mm before IPL#1 and 14.45 ± 9.99 mm after IPL#4. Tear break-up time (TBUT) was 3.15 ± 1.38 s before IPL#1 and 5.53 ± 2.34 s after IPL#4. Corneal staining scores (CFS) was 1.61 ± 3.09 before IPL#1 and 0.50 ± 0.78 after IPL#4. Lipid layer thickness (LLT) was 71.88 ± 26.34 nm before IPL#1 and 68.38 ± 24.16 nm after IPL#4. Lid margin abnormality score (LAS) was 1.96 ± 0.62 before IPL#1 and 0.86 ± 0.67 after IPL#4. Meibum expressibility (ME) was 1.67 ± 0.87 before IPL#1 and 1.03 ± 1.67 after IPL#4. Meibum quality (MQ) was 18.18 ± 6.34 before IPL#1 and 10.16 ± 5.48 after IPL#4. OSDI was 35.38 ± 19.97 before IPL#1 and 15.48 ± 34.32 after IPL#4. OSDI scores, DE, and MGD parameters significantly improved after the fourth IPL treatment but not ST and LLT. Conclusion Our study showed that the occurrence of superficial telangiectatic vessels were indirectly reduced by the decrease in skin temperature accompanying IPL treatments in patients with MGD.

Abstract
Meibomian gland dysfunction (MGD) is characterized by the obstruction and/or inflammation of the meibomian glands that result in decreased and altered meibum secretion. This results in deficiencies in the tear film lipid layer which contributes to increased evaporation and destabilization of the tear film. One of the mainstay therapies for MGD is medical devices that apply heat and/or pressure to the eyelids and promote the liquification and outflow of meibum into the tear film. Over the past two decades, there have been a surge of interest in diagnosing and managing MGD. As a result, numerous medical devices have been developed and each have their own unique approach to treating MGD. This narrative review was conducted to summarize the current state of knowledge on eyelid warming devices, specifically warm eye coverings, devices that direct heat and/or pressure to the eyelids, moisture chamber goggles, and light-based therapy. This review summarized 58 human clinical studies and found that most eyelid warming devices were efficacious in improving signs and symptoms in a wide range of MGD severities and were generally safe to use.

[PMID: 35888174 PMCID: PMC9318257 DOI: 10.3390/life12071086] [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: 05/16/2022] [Revised: 06/27/2022] [Accepted: 07/16/2022] [Indexed: 11/28/2022] Open
Abstract
Dry eye disease (DED) is most commonly caused by evaporative subtypes and mainly induced by meibomian gland dysfunction (MGD). Intense pulsed light (IPL) combined with meibomian gland expression (MGX) is a noninvasive treatment for improvement of ocular discomfort symptoms and MGD. In this prospective study between November 2020 and May 2022, the patients with MGD and abnormal meibomian expressibility that met the criteria of both ocular surface disease index (OSDI) ≥ 13 scores and standardized patient evaluation of eye dryness (SPEED) ≥ 8 scores were enrolled in Kaohsiung Veteran General Hospital. Three separate treatment sessions of IPL therapy combined with MGX were administered to the lower lids, with an interval of 28 days. Further tear film assessment included lipid layer thickness (LLT), tear meniscus height (TMH), noninvasive tear break-up time (NIBUT), and meibomian gland loss (MGL) either before or after first and third IPL therapy combined with MGX. In addition, lissamine green staining and pain scores were also recorded. We totally enrolled 37 patients of 74 eyes. Men accounted for 18.92% (7/37). The mean age was 54.51 ± 11.72 years. The mean OSDI scores were 58.12 ± 22, while the SPEED scores were 17.03 ± 5.98. The mean Schirmer’s test was 3.66 ± 2.43 mm. After three sessions of IPL treatment with MGX, the OSDI, SPEED, LLT, TMH, MGL, MGXS, and pain scores were significantly improved. For the MGX scores (MGXS) ≤ 20 group, lissamine green scores showed nearly significant improvements. For the MGXS > 20 group, TMH revealed statistical improvement. Noninvasive IPL therapy with MGX statistically improved not only dry eye symptoms, but also tear film assessments, including LLT, TMH, and MGL.

Kim M, Min J. Effect of Intense Pulsed-Light Treatment Using a Novel Dual-Band Filter in Patients with Meibomian Gland Dysfunction. J Clin Med 2022; 11:jcm11133607. [PMID: 35806889 PMCID: PMC9267678 DOI: 10.3390/jcm11133607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 06/16/2022] [Accepted: 06/20/2022] [Indexed: 11/18/2022] Open
Abstract
Background: This study evaluates the effect of intense pulsed-light (IPL) treatment in patients with meibomian gland dysfunction (MGD) using a novel dual-band filter (vascular filter, 530–650 nm and 900–1200 nm) and compares it with the effect and discomfort during treatment using a conventional filter. Methods: The medical records of 89 patients (89 eyes) with MGD who underwent IPL treatment were reviewed. Patients treated with the vascular filter or conventional 590 nm filter were designated as Group A or Group B, respectively. Patients underwent IPL treatment four times every four weeks. Ocular surface disease index (OSDI) scores, dry eye (DE), and MGD parameters were determined before the first IPL treatment and after the fourth IPL treatment. Visual analog scale (VAS) scores were obtained at every IPL treatment. OSDI, DE and MGD parameters, and VAS were compared between the groups. Results: OSDI, DE, and MGD parameters improved after the four IPL treatments in both groups. There were no significant differences, between the groups, in OSDI, DE, and MGD parameters, before the first IPL treatment and after the fourth IPL treatment. VAS at each of the IPL treatments was lower in Group B than in Group A. Conclusion: IPL treatment using the novel vascular filter for patients with MGD is effective compared with conventional IPL treatment for MGD patients.

Treatment Effect and Pain During Treatment With Intense Pulsed-Light Therapy According to the Light Guide in Patients With Meibomian Gland Dysfunction. Cornea 2022; 41:177-182. [PMID: 34469338 DOI: 10.1097/ico.0000000000002859] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 06/10/2021] [Indexed: 11/26/2022]
Abstract
PURPOSE We investigated whether there is a difference in the treatment effect and pain during the treatment of meibomian gland dysfunction (MGD) with intense pulsed-light (IPL) between new light guide and conventional light guide. METHODS We retrospectively reviewed medical records of 85 patients (170 eyes) who underwent IPL treatment of the upper and lower eyelids 3 times, at 3-week intervals, for MGD. Patients treated with the 6-mm or 8 × 15-mm cylindrical light guide were designated as group A or group B, respectively. The ocular surface disease index (OSDI), dry eye (DE), and MGD parameters were obtained before the first and after the third IPL treatments. Visual analog scale (VAS) scores were obtained at every IPL treatment. OSDI, DE, and MGD parameters and VAS scores were compared between the groups. RESULTS VAS scores at the first, second, and third IPL treatments were lower in group A than in group B. OSDI, DE, and MGD parameters were improved after 3 IPL treatments in both groups. There were no significant differences in OSDI, DE symptoms, and MGD parameters between before the first IPL treatment and after the third IPL treatment between the groups. CONCLUSIONS Using the new 6-mm cylindrical light guide for IPL treatment in patients with MGD induced less pain during treatment and had similar treatment effects to the conventional 8 × 15-mm light guide. The new 6-mm cylindrical light guide can be useful when treating patients with dark or hyperpigmented skin and for pediatric patients with low compliance.

Front Endocrinol (Lausanne) 2022; 13:973962. [PMID: 36187125 PMCID: PMC9520485 DOI: 10.3389/fendo.2022.973962] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 08/29/2022] [Indexed: 11/13/2022] Open
Abstract
PURPOSE This study compared the changes in tear inflammatory cytokine levels after intense pulsed light (IPL) combined with meibomian gland expression (MGX) (IPL group) and instant warm compresses combined with MGX (physiotherapy group) as treatments for meibomian gland dysfunction (MGD)-related dry eye disease (DED) to explore their similarities and differences in therapeutic mechanisms. METHODS This study was a post-hoc analysis of a randomized controlled trial. Thirteen patients with MGD-related DED were enrolled in each group and received three treatments correspondingly with 3-week intervals. The levels of 20 tear cytokines, namely, TNF-α, IL-6, MMP-9, CXCL8/IL-8, CXCL10/IP-10, IL-10, EGF, IL-6R, IL-1β, IFN-γ, lactoferrin, Fas ligand, IL-17A, LT-α, S100A9, LCN2/NGAL, IL-13, IL-12/IL-23p40, Fas, and CCL11/Eotaxin, were measured at baseline, before the second and third treatments, and 3 weeks after the third treatment. The primary outcome was the difference in cytokine levels between baseline and the last measurement, and the trends were analyzed at each measurement point. RESULTS At the last measurement, a significant decrease was observed in all tear cytokines for both IPL and physiotherapy groups compared with baseline. The IPL group showed greater reductions in IL-6, IL-6R, IL-1β, IL-13, and CCL11/Eotaxin than the physiotherapy group. TNF-α, CXCL8/IL-8, CXCL10/IP-10, IL-10, EGF, IL-1β, IFN-γ, and Lipocalin-2/NGAL levels continued to decrease with treatment time. Important interactions were found in the changes of IL-6 and IL-13 levels, where the levels first decreased and then slightly increased in the physiotherapy group after treatment, while they continued to decrease in the IPL group. CONCLUSIONS The mechanisms of IPL and physiotherapy in treating MGD-related DED were both associated with reducing inflammation, and the superiority of IPL could be attributed to its better inhibitory effect on inflammatory cytokines like IL-6. In addition, several cytokines were on a downward trend during treatment, suggesting that the vicious cycle of DED was suppressed.

Abstract
Purpose: To investigate the efficacy of intense pulsed light (IPL) treatment in patients with meibomian gland dysfunction (MGD) associated with Sjögren’s syndrome.Methods: This study included 43 patients with MGD and Sjögren’s syndrome. Patients received either IPL with meibomian gland expression (IPL/MGX) (n = 22) or MGX only (n = 21). Treatments were administered three times at a 3-week interval. Patients were followed up 6 weeks after the end of the treatment. Ocular Surface Disease Index (OSDI), tear film breakup time with fluorescein dye (FBUT), non-invasive tear breakup time, tear meniscus height (TMH), Schirmer test, SICCA ocular surface staining score, meibum quality score (MQS), and meibum expression score (MES) were evaluated at each visit. Meibomian gland dropouts (meiboscore) and tear film lipid layer grade were measured using keratography.Results: OSDI, FBUT, corneal surface staining score, MQS, meiboscore, and tear film lipid layer grade improved after IPL/MGX treatment (p < 0.05). In both treatment groups, MES significantly improved (p < 0.01 and p < 0.05 for IPL/MGX and MGX groups, respectively). The Schirmer test score, conjunctival surface staining score, and TMH after treatment were not significantly different between the groups. After treatment, the IPL/MGX group had significantly lower OSDI, FBUT, corneal staining score, MQS, and MES, but higher FBUT, compared with the MGX group (p < 0.05).Conclusions: IPL treatment effectively improved tear film, ocular surface parameters, meibomian gland function, and lipid layer grade in patients with Sjögren’s syndrome and MGD.

Abstract
To observe the clinical outcomes of intense pulsed light (IPL) for meibomian gland dysfunction (MGD) and identify its influencing factors.Forty-eight eyes of 48 patients with MGD were included. Subjects were followed up 5 times on day 1, day 15, day 30, day 45, and day 120, and underwent 3 sessions of the IPL treatment on day 1, day 15 and day 30. Gender, age, duration of MGD, time of video display terminal usage, and severity of MGD were recorded at baseline. At every visit, Ocular Surface Disease Index (OSDI), eyelid margin abnormality score, tear film breakup time, Schirmer I test (S ɪ t) and corneal fluorescein staining were recorded. The clinical parameters before and after 3 IPL treatments were compared. Univariate and multivariable logistic regression analyses were performed to explore influencing factors.Compared with baseline, the tear film breakup time was increased and the corneal fluorescein staining score and OSDI were significantly decreased on day 45 and day 120 (all P < .001). In univariate analysis, among the patients with a younger age (18-39 years), moderate MGD, higher baseline S ɪ t and higher baseline OSDI, the IPL treatment had a higher effective rate (P = .032, .004, .024, and .014 respectively). The MGD severity was strongly associated with effective IPL, and patients with moderate MGD had an OR of 22.454 compared with the severe MGD patients (OR = 22.454, 95% CI: 2.890-174.436, P = .003).IPL effectively improves clinical symptoms and some signs in MGD patients. Age, MGD severity, baseline S ɪ t and baseline OSDI are potential factors that may influence the clinical outcomes of IPL. MGD severity is an independent influencing factor.

Ther Clin Risk Manag 2021; 17:797-807. [PMID: 34393486 PMCID: PMC8355550 DOI: 10.2147/tcrm.s324423] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 07/21/2021] [Indexed: 12/14/2022] Open
Abstract
Aim The aim of this study was to investigate the relationship between levels of glycosylated hemoglobin (HbA1c) with meibomian gland dysfunction (MGD) in patients with type 2 diabetes mellitus (T2DM) and to further explore the related influencing factors. Methods Totally, 167 patients with T2DM and 68 non-diabetic subjects were selected. Further, T2DM patients were divided into 2 groups based on 7% HbA1c. Standard patient evaluation of eye dryness (SPEED), lipid layer thickness (LLT), partial blink (PB) ratio, percentage of partial glands (MGP), meibomian gland yielding liquid secretion (MGYLS), meibomian gland yielding secretion score (MGYSS), line of marx (LOM), tear break up time (TBUT), tear meniscus height (TMH) and Schirmer I test (SIT) were applied to evaluate meibomian gland function. Finally, the correlation between HbA1c and various indicators was also analyzed. Results Between HbA1c≥7% group and HbA1c<7% group, the differences in LLT (P=0.003), MGP (P<0.001), MGYLS (P=0.014) and TBUT (P=0.015) were all statistically significant. Compared with the non-diabetic group, LLT (P=0.020), MBP (P<0.001), MGYS (P< 0.001), TBUT (P<0.001), SIT (P=0.001), TMH (P=0.017) and LOM (P<0.001) were significantly different in HbA1c≥7% group, while the differences of MBP (P=0.031), MGYSS (P<0.001), SIT (P=0.001) and LOM (P<0.001) in HbA1c≤7% group were statistically significant. Besides, the prevalence of MGD in HbA1c≥7% group was evidently higher than that in non-diabetic group (P=0.002). Correlation analysis showed that HbA1c was significantly associated with the LTT and MGP. Conclusion HbA1c≥7% is likely to result in meibomian gland function dysfunctions in T2DM patients, especially related to LLT and MGP.
