The photothermal effect of intense pulsed light and LipiFlow in eyelid related ocular surface diseases: Meibomian gland dysfunction, Demodex and blepharitis. Heliyon 2024; 10:e33852. [PMID: 39040313 PMCID: PMC11261865 DOI: 10.1016/j.heliyon.2024.e33852] [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] [Received: 01/27/2024] [Revised: 06/25/2024] [Accepted: 06/27/2024] [Indexed: 07/24/2024] Open
Abstract
The treatment and management of ocular surface diseases have shifted towards a co-treatment approach focusing on overall ocular surface homeostasis. When treating issues related to the eye, it is essential to not only focus on the damaged or disabled areas but also consider the larger picture. Meibomian gland dysfunction (MGD), Demodex infection, and blepharitis all interact at the eyelid site and can cause damage to the ocular surface to varying degrees. Palpebral lesions disrupt the balance of ocular surface homeostasis, leading to dry eye and keratitis. Traditional treatments, such as manual physical hot compress massage, have limited effectiveness due to the structure of the eyelid. However, intense pulsed light (IPL) technology uses penetrating light energy to generate heat energy, which can eliminate inflammation of capillaries or kill Demodex. Additionally, the LipiFlow thermal effect and physical compression provide a more vital and longer-lasting therapeutic effect on MGD by excluding other primary causes of ocular surface inflammation. Therefore, personalized treatment techniques based on photothermal effects may be effective. In the future, IPL and LipiFlow may potentially dismiss immune-inflammation factors causing ocular surface disease or block the delivery of systemic immune-related diseases.

Abstract
BACKGROUND Dry eye disease (DED), a prevalent condition with a multifactorial etiology, significantly impacts global health by causing discomfort and visual disturbance. This historical cohort study evaluates the efficacy of Intense Pulsed Light (IPL) therapy on meibomian gland dysfunction (MGD)-related evaporative DED. METHODS The study involved 110 patients (220 eyes) who underwent IPL therapy. Ethical approval was secured, and informed consent was obtained from all participants. A Tearcheck® (ESWvision, Houdan, France) device was used for ocular surface evaluation, measuring tear film stability (NIFBUT, NIABUT), tear film quantity (CTMH, TTMH), and inflammation (OSIE). The study assessed tear film and ocular surface health across multiple IPL sessions. RESULTS Significant improvements were observed in subjective symptoms (EFT score increased from 29.10 ± 8.87 to 35.91 ± 7.03, p < 0.01), tear film stability (NIFBUT increased from 9.37 ± 6.04 to 10.78 ± 5.83 s, p < 0.01; NIABUT increased from 11.07 ± 4.98 to 12.34 ± 4.66 s, p < 0.01), and tear film surface evaluation (TFSE score decreased from 337.78 ± 414.08 to 206.02 ± 240.44, p < 0.01). Tear film quantity remained unchanged (CTMH and TTMH, p > 0.05). CONCLUSIONS IPL therapy is a promising treatment for DED, improving symptoms and ocular surface health. Further research is warranted to explore long-term efficacy and optimization.

Abstract
PURPOSE To demonstrate that intense pulsed light therapy (IPL) of the upper and lower eyelids with meibomian gland expression (MGX) is effective in improving dry eye disease due to meibomian gland dysfunction (MGD). METHODS Patients with ocular discomfort (Ocular Surface Disease Index -OSDI- above 13) and signs of MGD were recruited. All patients underwent OSDI, visual acuity (VA), intraocular pressure, Schirmer test, meibography, non-invasive tear breakup time (NITBUT), slit-lamp examination (corneal and conjunctival staining, hyperemia, gland expressibility, and meibum quality), tear osmolarity and lipid layer thickness. IPL was performed with Optima IPL (Lumenis Ltd.) following a standardized protocol on upper and lower eyelids of both eyes, with inferior eyelid MGX. Patients received four sessions separated by two weeks each. Four weeks after, examinations were repeated. RESULTS 160 patients (320 eyes) were included, of which 108 (67.5%) were women and mean age was 59.2 ± 15.08 (range 20-89). After four sessions, VA, OSDI, tear osmolarity, lipid layer thickness, NITBUT, hyperemia, corneal and conjunctival staining, gland expressibility, meibum quality, inferior eyelid Meiboscore and Schirmer test improved (all, p < 0.027). Changes in OSDI, initial and average NITBUT increased with dry eye disease severity (according to OSDI). Increased pre-treatment OSDI, hyperemia, corneal and conjunctival staining and Schirmer test were associated with an improvement in OSDI (all, p < 0.040). No adverse events were noted. CONCLUSIONS The combination of IPL on upper and lower eyelids with MGX is safe and effective for the treatment of MGD. Patients with severe dry eye disease present greater improvements.

Abstract
INTRODUCTION To assess the efficacy and safety of the combination of microblepharoexfoliation (MBE), intense pulse light (IPL) and meibomian gland expression (MGX) for treatment of meibomian gland dysfunction (MGD). METHODS This was a prospective, parallel-control trial conducted from April 2022 to January 2023. Participants were assigned to receive either three sessions of MBE-IPL-MGX treatment and home-based therapy (treatment group) or home-based therapy alone (control group). Outcome measures were assessed at baseline and after 2-month follow-up. RESULTS Seventy eyes of 70 patients were enrolled. MBE-IPL-MGX treatment achieved better improvements than home-based therapy in ocular surface disease index (OSDI) and symptom assessment in dry eye (SANDE) scores, noninvasive tear film break-up time (NIBUT), lipid layer grade (LLG), loss area meibomian gland (LAMG) and meibomian gland yielding secretion score (MGYSS). The mean differences between the two groups were as follows: OSDI (- 11.23 ± 4.68 points, P < 0.001), SANDE (- 24.63 ± 13.41 points, P < 0.001), NIBUT (1.3 ± 1.57 s, P = 0.033), LLG (0.4 ± 0.04 points, P = 0.003), LAMG (- 2.85 ± 1.69%, P = 0.023) and MGYSS (7.5 ± 2.32 points, P < 0.001). In addition, the increment (Δ) of MGYSS after MBE-IPL-MGX treatment was significantly higher in MGD grades 2 and 3 (all P < 0.001). CONCLUSIONS MBE-IPL-MGX treatment is an effective and well-tolerated procedure that improves dry eye symptoms and signs as well as meibomian gland secretions in patients with MGD. In addition, this treatment is recommended for MGD grades 2 and 3.

Abstract
Dry eye is a widespread chronic inflammatory disease that causes fatigue, tingling, burning, and other symptoms. Dry eye is attributed to rheumatic diseases, diabetes, hormone disorders, and contact lenses, which activate inflammatory pathways: mitogen-activated protein kinases (MAPK) and nuclear factor-B (NF-κB), promote macrophage inflammatory cell and T cell activation, and inflammation factors. Clinicians use a combination of anti-inflammatory drugs to manage different symptoms of dry eye; some of these anti-inflammatory drugs are being developed. This review introduces the dry eye inflammation mechanisms and the involved inflammatory factors. We also elucidate the anti-inflammatory drug mechanism and the detection limits.

Abstract
PURPOSE The purpose of the study was to evaluate the quality of life (QOL) improvement in evaporative dry eye patients after treatment with intense pulsed light (IPL) therapy compared to punctal plug insertion. METHODS A prospective comparative interventional study included 30 patients with moderate-to-severe evaporative dry eye. Patients' QOL affection before and after treatment was assessed by the Ocular Surface Disease Index (OSDI) questionnaire. Fifteen patients were treated with IPL therapy (Group 1). The other 15 patients were treated with silicone punctal plug insertion (Group 2). RESULTS Improvement of patients' QOL was noticed in all patients of Group 1, with significant improvement of OSDI score from a mean value of 56.9 to 22.9 (P = 0.001). Improvement was noticed in 80% of Group 2 patients (mean OSDI score pretreatment: 53.8 and posttreatment: 31.7, P = 0.017). The tear breakup time (TBUT) in Group 1 significantly improved from a mean of 3.2 s to 5.9 s (P = 0.001), whereas it showed no significant changes in Group 2 (mean TBUT pretreatment: 3.6 s and posttreatment: 3.9 s, P = 0.654). Complications occurred in 13.3% in Group 2, including punctal granuloma and proximal canalicular obstruction. No adverse effects were recorded in Group 1. CONCLUSION IPL therapy had better results with more improvement of patients' QOL compared to punctal plugs. It also showed a better safety profile with no reported complications.

Abstract
PURPOSE Meibomian gland dysfunction (MGD) is the leading cause of dry eye syndrome. It is a frequent and underdiagnosed condition with a significant socioeconomic impact. We propose here the evaluation of a platform combining intense pulsed light and photo-biomodulation in the treatment of Meibomian gland dysfunction. METHODS We conducted a retrospective study at Brest University Hospital analyzing a cohort of 74 eyes (37 patients) at 1 month and 3 months after a protocol of 3 Eye-Light® (Espansione Group, Italy) sessions 14 days apart between January 2019 and April 2020. The primary outcome was the change in OSDI quality of life score. Secondary outcomes were the SPEED questionnaire score; tear break-up time (BUT), Oxford score, non-invasive break-up time (NIBUT), lipid layer thickness, lacrimal meniscus height and Meibomian gland atrophy rate. Tolerance of the treatment was also evaluated. RESULTS We found a significant improvement in OSDI scores at 1 month (-17.32; 95% CI (-25.84; -8.79), P<0.0001) and 3 months (-16.95; 95% CI (-25.26; -8.64), P<0.0001). The SPEED score, BUT, Oxford score, Meibomian gland atrophy and NIBUT were also statistically significantly improved. Tolerance to treatment was very good despite two cases of herpetic keratitis, which resolved on treatment. CONCLUSION Treatment with the Eye-Light® in three sessions every two weeks significantly reduced symptoms and ocular surface damage in patients with MGD. This data suggests that the use of Eye-Light® may represent a good option for patients with MGD.

Abstract
Background: Dry eye disease (DED) is a complex ocular surface inflammatory disorder with a multifactorial etiology. Therapies such as intense pulsed light (IPL) and heated eye mask (HEM) have been reported to improve the tear film lipid layer (TFLL) and signs and symptoms of DED. Methods: This randomized study aimed to compare the effects of IPL combined with HEM (IPL+HEM) group, IPL group, and control group in participants with evaporative DED. All participants were examined at baseline (D0), day 21 (D21), day 42 (D42), and day 84 (D84) for noninvasive tear breakup time (NITBUT), TFLL, corneal conjunctival staining (CS), meibomian gland quality (MGQ), meibomian gland expressibility (MGEx), and Ocular Surface Disease Index (OSDI). Results: The mean age of participants was IPL+HEM: 28.06 ± 3.88 years, IPL: 29.88 ± 4.68 years, and control: 28.52 ± 3.77 years. At D84, significant improvements in TFLL (p < 0.05), noninvasive tear breakup time (NITBUT) (p < 0.05), corneoconjunctival staining (CS) (p < 0.05), MGQ (p < 0.05), MGEx (p < 0.05), and OSDI (p < 0.05) were found in the IPL+HEM and IPL groups, whereas the control group had no significant improvements. Furthermore, ΔTFLL significantly correlated with ΔNITBUT (r = -0.678, p < 0.001), ΔCS (r = 0.321, p < 0.001), ΔMGQ (r = 0.669, p < 0.001), ΔMGEx (r = 0.598, p < 0.001), and ΔOSDI score (r = 0.649, p < 0.001). Conclusions: IPL therapy in combination with HEM and IPL therapy only can significantly improve the quality of TFLL and clinically reduce the sign and symptoms of evaporative DED. However, IPL therapy in combination with HEM was found to be more effective than IPL therapy alone.

Abstract
The word "elective" refers to medications and procedures undertaken by choice or with a lower grade of prioritization. Patients usually use elective medications or undergo elective procedures to treat pathologic conditions or for cosmetic enhancement, impacting their lifestyle positively and, thus, improving their quality of life. However, those interventions can affect the homeostasis of the tear film and ocular surface. Consequently, they generate signs and symptoms that could impair the patient's quality of life. This report describes the impact of elective topical and systemic medications and procedures on the ocular surface and the underlying mechanisms. Moreover, elective procedures performed for ocular diseases, cosmetic enhancement, and non-ophthalmic interventions, such as radiotherapy and bariatric surgery, are discussed. The report also evaluates significant anatomical and biological consequences of non-urgent interventions to the ocular surface, such as neuropathic and neurotrophic keratopathies. Besides that, it provides an overview of the prophylaxis and management of pathological conditions resulting from the studied interventions and suggests areas for future research. The report also contains a systematic review investigating the quality of life among people who have undergone small incision lenticule extraction (SMILE). Overall, SMILE refractive surgery seems to cause more vision disturbances than LASIK in the first month post-surgery, but less dry eye symptoms in long-term follow up.

Abstract
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.

Abstract
Given the various ocular manifestations of limbal stem cell insufficiency, an awareness of the genetic, acquired, and immunological causes and associated additional treatments of limbal stem cell deficiency (LSCD) is essential for providers. We performed a comprehensive review of the literature on the various etiologies and specific therapies for LSCD. The resources utilized in this review included Medline (PubMed), Embase, and Google Scholar. All English-language articles and case reports published from November 1986 through to October 2022 were reviewed in this study. There were collectively 99 articles on these topics. No other exclusion criteria were applied. Depending on the etiology, ocular manifestations of limbal stem cell deficiency range from dry eye syndrome and redness to more severe outcomes, including corneal ulceration, ocular surface failure, and vision loss. Identifying the source of damage for LSCD is critical in the treatment process, given that therapy may extend beyond the scope of the standard protocol, including artificial tears, refractive surgery, and allogeneic stem cell transplants. This comprehensive review of the literature demonstrates the various genetic, acquired, and immunological causes of LSCD and the spectrum of supplemental therapies available.

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
PURPOSE To evaluate the effect of the intense pulsed light (IPL) and meibomian gland (MG) expression (MGX) combination therapy according to the total numbers of sessions in the meibomian gland dysfunction (MGD). METHODS Ninety patients with MGD were included. Patients had maximal five sessions of IPL (Aqua Cel, Jeisys Medical) and MGX combination therapy at 2-week intervals. The ocular surface disease index (OSDI) questionnaire score, MG profile grades, tear matrix metalloproteinase-9 (MMP-9), tear break-up time (BUT), tear osmolarity, tear secretion, and corneal erosions were evaluated. RESULTS The number of patients who had a total of one to five sessions (1S to 5S) was 10, 25, 17, 20, and 18, respectively. The time-serial decrease of OSDI scores was significant in patients who had three or more sessions (3S, p = 0.002; 4S, p < 0.001; 5S, p < 0.001). The MG expressibility grade decreased with two or more sessions (2S-5S, p < 0.001), but the meibum quality significantly improved with all sessions (1S, p = 0.012; 2S, p = 0.024; 3S, p = 0.015; 4S, p < 0.001; 5S, p < 0.001). Although tear BUT increased even in patients with one session (1S, p = 0.040; 3S, p = 0.005; 4S, p = 0.006; 5S, p = 0.021), tear MMP-9, osmolarity, Schirmer I, and corneal erosions were not improved in every number of sessions. The female sex was the sole contributor to the final symptomatic improvement (p = 0.042), and the MGD stages were not related to the final OSDI decrease. CONCLUSIONS The OSDI score, MGD grades, and BUT were improved after the IPL and MGX combination therapy in MGD patients. Unlike MGD grades and tear film instability might be improved just after a few sessions, the overall subjective relief was accomplished in three or more sessions.

Abstract
To describe the efficacy and safety of intense pulsed light (IPL) applied directly on the eyelids of patients with Meibomian gland dysfunction (MGD) without corneal shield protector. Observational retrospective single centre study where patients underwent 3 treatment sessions of IPL with 2 weeks of interval. The IPL was carried out with Lumenis OPT M22 with a double pass technique of 12 impacts on the infraorbital/lower eyelid region with the 15 × 35 mm guide light (step 1) and a double pass technique of 3 impacts over the upper eyelids with the 8 × 15 mm guide light (step 2). The follow up was conducted through Oculus Keratograph 5 M. 30 patients were enrolled in the study. Although there were no significant differences (p > 0.05), non-invasive tear break-up time, ocular redness, and OSDI questionnaire improved during the 3 IPL sessions. A significant improvement (p = 0.024) in the percentage of meibomian gland loss was also observed. Regarding tear meniscus, it was found similar measurements before and after treatment. No serious adverse effects were reported during the procedure or in subsequent follow-up. Preliminary results suggest that IPL therapy applied directly on the eyelids without corneal shield could be safe and effective in the treatment of MGD.

Abstract
To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for the treatment of refractory multiple and recurrent chalazia without surgery or curettage. This was a retrospective controlled study. Patients with multiple and recurrent chalazia, who had performed the conventional treatment at least 2 months without any surgery or curettage, were enrolled in this study. Twenty-nine consecutive multiple recurrent chalazia (12 patients) were assigned to receive either the combination of IPL and MGX or MGX alone as a control. Each eye underwent one to four treatment sessions with 2-week intervals. Parameters were evaluated before and 1 month after the final treatment session. Clinical assessments included symptom, size of each chalazion, lid margin abnormalities, corneal and conjunctival fluorescein staining, meibum grade, the number of Demodex mites, the Schirmer value and meiboscore. All parameters except meiboscore and the Schirmer value were significantly improved with IPL-MGX therapy, whereas only meibum grade was significantly improved with MGX alone. There were no adverse events which occurred in either group. IPL-MGX was safe and effective for multiple and recurrent chalazia without surgery or curettage by reducing the size of chalazion and improving lid margin abnormalities and meibum grade.

Abstract
PURPOSE Dry eye disease (DED) is a leading cause of ocular morbidity worldwide. This study evaluates the effects of combined light therapy [intense pulsed light (IPL) and low-level light therapy (LLLT)] on clinical and molecular outcomes in evaporative DED with meibomian gland dysfunction (MGD). METHODS This prospective study evaluated 94 eyes (47 subjects) with chronic MGD treated with combined light therapy. Patients underwent a detailed evaluation of MGD and DED using the Ocular Surface Disease Index, dry eye tests-tear breakup time and Schirmer test, ocular surface staining, meibomian gland expressibility scoring, and meibography. Patients underwent a single session of combined light therapy (IPL + LLLT treatment) using the Eye-light device. All these tests were repeated at 3 and 6 months after treatment. Tear fluid and ocular surface wash samples were collected from a subset of patients before and after treatment for cellular and secreted immune factor profiling by flow cytometry. RESULTS Combined light therapy (IPL + LLLT) demonstrated a marked improvement in the clinical metrics studied. Three months after treatment, Ocular Surface Disease Index showed a significant reduction in 95.6% ( P < 0.0001), tear breakup time increased in 72.3% ( P < 0.0001), and meibomian gland expressibility scoring increased in 80.8% ( P < 0.0001) of the eyes. These effects were observed to be sustained during the 6-month follow-up visit. Significant ( P < 0.05) reduction in tear fluid levels of interleukin-1β, interleukin-17F, and MMP9; MMP9/TIMP1 ratio; and ocular surface B-cell proportions was observed. CONCLUSIONS Combined light therapy shows promising results in patients with chronic MGD and DED, even in recalcitrant cases. Clinical and molecular factor alterations support the improved symptomatology and reduced inflammation.

Abstract
Introduction This study aimed to evaluate the efficacy and safety of a new-generation intense pulsed light (IPL) device in improving the symptoms and signs of meibomian gland dysfunction (MGD)-related dry eye, and compare it with a traditional IPL device. Methods This multicenter randomized controlled trial enrolled 132 patients with MGD-related dry eye from two centers. Patients were randomly assigned into the new-generation IPL (Eyesis) group or traditional IPL (E-Eye) group, and then blinded to receive treatment on days 0 and 7. Ocular Surface Disease Index (OSDI), tear meniscus height (TMH), tear breakup time (TBUT), corneal fluorescein staining (CFS), Schirmer test, and meibomian gland signs were evaluated on days 0, 7, and 14. The primary outcome was defined as the effective rate of treating MGD at day 14. Any adverse events were recorded for safety assessment. Intergroup comparisons and non-inferiority analysis were performed. p values less than 0.05 were considered statistically significant. Results Basic information showed no significant difference between treatment groups. The intergroup difference of the effective rate was − 1.7% in the left eye and 1.6% in right eye, verifying the non-inferiority of the Eyesis device (p = 0.927). Significant improvements in OSDI, TBUT, Schirmer test, TMH, CFS, and meibomian gland signs were observed in Eyesis group on days 7 and 14 (all p < 0.05). Compared to the E-Eye group, the Eyesis group achieved more significant improvements in OSDI, TBUT, Schirmer test, TMH, and meibum quality (all p < 0.05). There was no significant difference in the incidences of adverse events between groups (p = 1.000). Conclusions The new-generation IPL was effective and safe in relieving the symptoms and signs of MGD-related dry eye, exhibiting a non-inferior effective rate compared to the traditional IPL. Additionally, Eyesis showed more clinical benefits over E-Eye in alleviating symptoms, increasing tear film stability and improving meibomian gland function.

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.

Vigo L, Pellegrini M, Carones F, Scorcia V, Giannaccare G. Outcomes of serial sessions of Activa mask combined with intense pulsed light therapy in patients with Meibomian gland dysfunction. BMC Ophthalmol 2022; 22:313. [PMID: 35854254 PMCID: PMC9295515 DOI: 10.1186/s12886-022-02538-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Accepted: 07/11/2022] [Indexed: 12/18/2022] Open
Abstract
Background To evaluate the effects on ocular surface signs and symptoms of serial sessions of heating and vibrating eye mask followed by intense pulsed light (IPL) therapy for the treatment of dry eye disease owing to meibomian gland dysfunction (MGD). Methods Consecutive patients with MGD whose signs and symptoms were not satisfactorily controlled with conventional therapy were included. Patients received 3 treatments performed at day 1, 15, and 45 incorporating a session with a newly-developed eye mask (Activa, SBS Sistemi, Turin, Italy) immediately followed by IPL therapy (E > Eye device, E-Swin, Paris, France). Patients were examined before the first session (T0) and 30 days after the last session (T1) for the measurement of: noninvasive break-up time (NIBUT); lipid layer thickness (LLT); tear meniscus height (TMH); meibomian gland loss (MGL); tear osmolarity. Ocular discomfort symptoms were ascertained by ocular surface disease index (OSDI) questionnaire. Results Thirty patients were ultimately included in the study. At T1, all objective ocular surface parameters improved significantly, except for TMH: NIBUT and LLT increased from 6.4 ± 1.7 to 8.6 ± 1.7 s and from 57.7 ± 15.5 to 81.3 ± 12.0 μm (all P < 0.001), while MGL and tear osmolarity decreased from 21.1 ± 17.3 to 17.0 ± 14.1% and from 302.0 ± 8.5 to 295.7 ± 6.9 mOsm/L (respectively, P = 0.004 and P < 0.001). In parallel, OSDI score decreased significantly from 49.8 ± 13.5 to 29.8 ± 10.6 (P < 0.001). In the historical control group of patients who underwent only IPL, NIBUT, LLT, tear osmolarity and OSDI improved significantly but not MGL and TMH. Conclusions Serial sessions incorporating the application of an eye mask producing heating and vibration immediately followed by IPL therapy are able to improve all ocular surface parameters as well as ocular discomfort symptoms in MGD patients.

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.

Safety and Feasibility of Low Fluence Intense Pulsed Light for Treating Pediatric Patients with Moderate-to-Severe Blepharitis. J Clin Med 2022; 11:jcm11113080. [PMID: 35683467 PMCID: PMC9181558 DOI: 10.3390/jcm11113080] [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: 03/03/2022] [Revised: 05/19/2022] [Accepted: 05/27/2022] [Indexed: 11/17/2022] Open
Abstract
To explore the safety and feasibility of low fluence intense pulsed light (IPL) for treating pediatric patients with moderate-to-severe blepharitis and to analyze potential factors associated with the recovery of meibomian glands (MG) dropout, a retrospective, noncomparative study, including 17 blepharitis patients (33 eyes) aged between 5 and 16 years old was conducted. All of the participants were given 4 continuous sessions of low-fluence (9−12 J/cm2) IPL at 3−4 week intervals. Corneal fluorescein staining (CFS), tear breakup time (BUT), inferior tear meniscus height, Demodex presence, and MG morphology were examined before and after the treatment. Results indicated that CFS, BUT and MG morphology (central/total gland area ratio and gland signal index) had significantly improved (p < 0.05). Symptoms and signs such as severe corneal neovascularization, limbal pannus and conjunctival congestion also subsided. Among age, gender, presence of Demodex and interval before diagnosis, age initiating the formal treatment was confirmed as a negatively correlated factor of the recovery of MG dropout (p = 0.032, B = −1.755). No notable adverse events were reported. In conclusion, low fluence IPL seems to be a safe and effective alternative for moderate-to-severe pediatric blepharitis, and MG dropout is prone to recover in younger patients.

Abstract
OBJECTIVES To assess 1-week and 1-month efficacy of Systane iLux thermal pulsation treatment for meibomian gland dysfunction (MGD). METHODS This prospective, nonrandomized, open-label, multicenter study enrolled 30 adult patients (60 eyes) who had a Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire score greater than 6 and total meibomian gland secretion (MGS) score equal to or less than 12 in each eye. All participants received thermal pulsation treatment bilaterally. Primary efficacy measures included MGS score (sum of grades for 15 glands graded on a scale of 0-3; 0 [no secretion], 1 [inspissated], 2 [cloudy], and 3 [clear liquid]) and tear breakup time (TBUT). Secondary efficacy measures were SPEED and Ocular Surface Disease Index (OSDI) scores. RESULTS The mean age of patients was 52.9±11.9 years. After 1 week, the mean MGS score improved significantly from 4.1±3.1 to 15.8±7.1 (right eye, OD) and 3.7±3.1 to 16.7±7.6 (left eye, OS); mean TBUT improved significantly from 4.9±4.1 to 8.4±3.6 (OD) and 5.2±4.2 to 8.9±3.9 (OS); and mean SPEED and OSDI scores improved significantly from 16.1±5.3 to 7.2±6.1 and 45.2±21.3 to 19.0±16.8, respectively (all P<0.001). After 1 month, the mean MGS score improved to 18.3±8.2 (OD) and 18.6±7.3 (OS); mean TBUT improved to 9.7±3.8 (OD) and 9.6±3.5 (OS); and mean SPEED and OSDI scores improved to 7.0±5.6 and 16.7±14.5, respectively (all P<0.001). No adverse events were reported. CONCLUSIONS Systane iLux thermal pulsation treatment for MGD resulted in a statistically significant increase in meibomian gland secretion, improvement in tear film stability, and reduction in dry eye symptoms as early as both 1 week and 1 month.

Abstract
Purpose: To investigate the efficacy of intense pulsed light (IPL) combined with deproteinized calf blood extract (DCBE) eye drops for dry eye disease (DED) patients with nociceptive ocular pain. Methods: In this prospective, one-center, interventional study, 23 subjects with DED and ocular pain were treated with a combination of IPL and DCBE eye drops for four sessions at a four-week interval. Subjective and objective assessments on nociceptive pain and dry eye were examined and analyzed. Results: The visual analog scale (VAS), ocular surface disease index, ocular pain assessment survey (OPAS), patient health questionnaire-9 items, generalized anxiety disorder (GAD-7), Athens insomnia scale, corneal fluorescein staining score, meibomian gland secretion quality, and expressibility scores were significantly reduced after the treatment. Tear break-up time and Schirmer I test increased significantly. The brand density of corneal nerves and neuropeptide substance P also significantly increased. OPAS, GAD-7, meibomian gland secretion quality, and expressibility scores were essential factors affecting the VAS changes. Conclusions: IPL combined with DCBE drop therapy was effective for DED patients with ocular pain. With such treatment, both DED symptoms and the sensation of ocular pain may be improved.

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.

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
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.

Abstract
Purpose To assess the therapeutic efficacy of a combinational therapy, including conventional treatment and intense pulsed light (IPL) technique on sleep quality of patients with meibomian gland dysfunction (MGD). Methods Fifty participants with a clinical diagnosis of MGD were enrolled in this study. Participants underwent three sessions of IPL therapy. There was a 2-week interval between IPL sessions 1 and 2 and 1 month between sessions 2 and 3. Treatment was supplemented with conventional home-based therapy (including lid hygiene, warm compress, eyelid massage, and lid margin scrub) for MGD. Dry eye symptomatology, tear film, and ocular surface parameters were evaluated at baseline (day 0) and days 15, 45, and 75. Sleep quality was assessed before and after the study using Pittsburgh Sleep Quality Index (PSQI). Results PSQI components improved significantly at day 75 in comparison with the baseline (all P < 0.05). Ocular Surface Disease Index (OSDI) score, noninvasive Keratograph tear break-up time (NIKBUT), fluorescein tear break-up time (FTBUT), meibomian gland expressibility, meibum quality score, and tear osmolarity improved at follow-up visits (P < 0.05). Younger patients showed more improvement in NIKBUT, sleep quality, and duration (P = 0.024, P = 0.047, and P = 0.008). Sleep latency decreased with increased NIKBUT and FTBUT and decreased OSDI score (P = 0.001, P = 0.005, and P = 0.041). Conclusions The treatment of MGD is effective for improving sleep quality. Younger patients may preferentially benefit from the treatment.

Abstract
CLINICAL RELEVANCE Meibomian gland dysfunction is the main cause of evaporative dry eye disease and can lead to ocular discomfort and ocular surface damage. Early diagnosis and management of this condition can prevent its impact on patients 'visual health and quality of life. BACKGROUND In the last decade, intense pulsed light therapy (IPL) has been introduced as a therapeutic option for patients with meibomian gland dysfunction (MGD). Various treatment modalities and protocols have been reported to increase the efficacy of this technique. This study aimed to assess the efficacy of a novel five-flash IPL technique in combination with home-based therapy and to compare it with conventional home care alone in patients with MGD. METHODS In a randomised controlled trial, 100 symptomatic MGD patients were enrolled. The treatment group underwent three sessions of a five-flash IPL therapy. For all participants, eyelid warming, lid hygiene and lubricant therapy was prescribed. Ocular surface parameters were compared for control and treatment groups. RESULTS Ocular Surface Disease Index (OSDI), non-invasive keratograph tear break up time (NIKBUT), fluorescein TBUT, MG expressibility, meibum quality and tear osmolarity were improved at follow up visits in both groups (p < 0.05). On day 75, NIKBUT was significantly higher in the IPL group (p = 0.045). The IPL treatment effect was not statistically significant (p > 0.05), except for bulbar and limbal hyperaemia (p = 0.02 and p = 0.02). In both groups, younger patients showed more improvement in NIKBUT (p = 0.02, r = -0.32; p < 0.001, r = -0.52). CONCLUSION IPL therapy combined with conventional home-based therapy, and home care alone are both effective for patients with MGD. IPL may have an additional role in the improvement of ocular hyperaemia.

Abstract
Meibomian gland dysfunction (MGD) has become a prevalent ocular surface disorder. Its pathogenesis is regarded as a self-perpetuating inflammatory vicious circle. Intense Pulsed Light (IPL) treatment was recently applied to improve the meibomian gland function and reduce symptoms of MGD. However, studies investigating the change of specific inflammatory cytokines during IPL treatment remained sparse. To further figure out how IPL treatment modulates the inflammatory cytokines in tears of MGD, we therefore performed a cross-sectional study and enrolled 32 patients from March 2019 to December 2020. The patients received 3 sessions of IPL treatment (10 to 16 J/cm2) at 4-week interval. The signs and symptoms of MGD were evaluated by ocular surface disease index (OSDI), tear film breakup time (TBUT), and meibomian gland yield secretion score (MGYSS). The clinical evaluators and tear samples were analyzed at baseline and at each IPL treatment session. Concentrations of (chemokine ligand) CXCL1, (C-C motif chemokine) CCL11, (tumor necrosis factor) TNF-α, (interferon) IFN-γ, (interleukin) IL-2, IL-6 and (tissue inhibitor of metalloproteinase) TIMP-1were measured by Quantibody Human Dry Eye Disease Array1. OSDI significantly decreased after IPL treatment compared with baseline. TBUT and MGYSS increased consecutively during treatment. CXCL1, CCL11, TNF-α, IFN-γ, IL-2, IL-6 presented significantly decrease and TIMP-1 showed significantly increase from the pretreatment baseline. The changed concentrations of TNF-α, IFN-γ, IL-2, TIMP-1 correlated with TBUT, the changed values of CXCL1, TNF-α, IFN-γ, CCL11, IL-2, IL-6, TIMP-1 correlated with MGYSS, and the changed concentrations of CXCL1, IFN-γ, CCL11, IL-2, IL-6 correlated with TIMP-1. The data supported IPL treatment could significantly relieve both signs and symptoms of MGD. The therapeutic effect of IPL treatment may originate from regulation of inflammatory cytokines including CXCL1, TNF-α, IFN-γ, CCL11, IL-2, IL-6, and TIMP-1.

Abstract
PURPOSE OF REVIEW Dry eye disease (DED) is a multifactorial disease affecting approximately 5-50% of individuals in various populations. Contributors to DED include, but are not limited to, lacrimal gland hypofunction, meibomian gland dysfunction (MGD), ocular surface inflammation, and corneal nerve dysfunction. Current DED treatments target some facets of the disease, such as ocular surface inflammation, but not all individuals experience adequate symptom relief. As such, this review focuses on alternative and adjunct approaches that are being explored to target underlying contributors to DED. RECENT FINDINGS Neuromodulation, stem cell treatments, and oral royal jelly have all been studied in individuals with DED and lacrimal gland hypofunction, with promising results. In individuals with MGD, devices that provide eyelid warming or intense pulsed light therapy may reduce DED symptoms and signs, as may topical Manuka honey. For those with ocular surface inflammation, naturally derived anti-inflammatory agents may be helpful, with the compound trehalose being farthest along in the process of investigation. Nerve growth factor, blood-derived products, corneal neurotization, and to a lesser degree, fatty acids have been studied in individuals with DED and neurotrophic keratitis (i.e. corneal nerve hyposensitivity). Various adjuvant therapies have been investigated in individuals with DED with neuropathic pain (i.e. corneal nerve hypersensitivity) including nerve blocks, neurostimulation, botulinum toxin, and acupuncture, although study numbers and design are generally weaker than for the other DED sub-types. SUMMARY Several alternatives and adjunct DED therapies are being investigated that target various aspects of disease. For many, more robust studies are required to assess their sustainability and applicability.

Abstract
Purpose To analyse the clinical outcome in patients with meibomian gland dysfunction (MGD) who underwent intense pulsed light (IPL) plus low-level light therapy (LLL). Materials and Methods The prospective non-comparative study included identified by MGD patients with altered interferometry and lower loss area of the meibomian glands (LAMG), who underwent IPL plus LLL, between July 2020 and August 2020. A multimodal assessment was performed before, 2–3 weeks, and 6 months after treatment. The main outcome was lipid layer thickness (LLT) and the secondary outcomes were the ocular surface disease index (OSDI) score, presence of corneal fluorescein staining (CFS), blink rate (BR), Schirmer test (ST), tear meniscus height (TMH), tear osmolarity (OSM), non-invasive break-up time (NIBUT) and LAMG. Results This study included 62 eyes of 31 patients, 61.3% female, with a mean age of 66.94±9.08 years at the time of IPL plus LLL treatment. LLT (<0.001) grades improved 6 months after treatment. The mean OSDI score improved (p<0.001) from 45.02±21.17 (severe symptoms) to 22.35±17.68 (moderate symptoms) at 2–3 weeks and 8.24±17.9.91 (normal) at 6 months after treatment. CFS was identified in 51.6% (32/62) before and in 45.2% (28/62) 6 months (p=0.293) after treatment. ST (p=0.014) grades improved; OSM grades mild worsened (p<0.001); TMH, NIBUT and LAMG grades did not modify 6 months after treatment. No patient suffered any adverse effects. Conclusion IPL combined with LLL was effective and safe, improving the lipid layer thickness in MGD and decreasing the level of symptoms.

Abstract
Background and Objectives: Evaporative dry eye disease is frequently associated with meibomian gland dysfunction. Patients are often unhappy because of daily drops, care burden, and suboptimal conventional treatments. In this study, we assessed the efficacy of a novel device, the Eye-light®, a combination of intense pulsed light therapy and low-level light therapy, as a novel treatment for meibomian gland dysfunction and dry eye disease. Materials and Methods: This was a retrospective, single-center study carried out over a 6-week period, in which 22 eyes from 11 patients were included. Each patient received four combined light therapy treatment sessions, once weekly over 4 weeks. Patients underwent a clinical examination and filled out a standardized questionnaire to evaluate symptoms one week prior to treatment, and one week after the fourth session. Results: Combined light therapy improved several ocular surface outcome measures in our patients. This study demonstrates that this adjunctive treatment significantly improves the ocular surface and quality of life of patients with dry eye disease and meibomian gland dysfunction. Conclusions: Combined light therapy may be included in meibomian gland dysfunction treatment protocols as an adjunctive rescue treatment.

Abstract
Purpose To assess the effectiveness of a combination of intense pulsed light and low-level light therapy (IPL/LLLT) for the treatment of dry eye. Study Design Retrospective before-after single-center clinical study. Materials and Methods Patients diagnosed with dry eye, refractory to conventional treatment, underwent four sessions of combined IPL/LLLT over 3 months. The Ocular Surface Disease Index (OSDI) questionnaire, non-invasive breakup time (NIBUT), tear film osmolarity and meniscus height were measured 6 months before intervention, at baseline, post-intervention (3 months), 9 and 15 months. Results NIBUT, osmolarity and meniscus height significantly worsened during the 6 months before treatment, whereas symptoms did not change. OSDI scores significantly improved at post-intervention (MD = −44.0, 95% CI −38.1, −50.0), and then increased again until the at last follow-up, but still significantly different from baseline (MD = −30.0, 95% CI −23.4, −36.8). The three clinical signs showed a similar pattern, with one-year improvements of 3.6 seconds for the NIBUT (95% CI 3.1, 4.2, p <0.001), 28 mOsm/L for osmolarity (95% CI 23.6, 32.4, p <0.001) and 0.03 mm for meniscus height (95% CI 0.02, 0.04, p <0.001). No adverse effects were observed. Conclusion IPL/LLLT is safe and produces an important reduction in symptoms and signs of dry eye disease, still relevant one year after the end of treatment in a sample with high symptoms’ severity. Therefore, it represents a promising treatment option for patients who do not improve with conventional treatment. Randomized trials are needed to determine the added benefit provided by LLLT.

Abstract
Objectives We aimed to evaluate the efficacy of periocular intense pulsed light (IPL) therapy in the treatment of moderate to severe acute blepharitis or blepharoconjunctivitis. Materials and Methods This was a retrospective study performed in one institution. Eleven patients who received bilateral periocular IPL therapy using an IPL device (E>Eye, ESwin, Paris, France) were retrospectively evaluated. The following findings obtained at baseline and 10 weeks after the treatment were recorded: slit-lamp examinations; symptom scores of the Compression of the Eyelid (COTE) grading system and Ocular Surface Disease Index (OSDI); ocular surface staining with Oxford grading scale (OXFORD) scores; lipid layer thickness (LLT); and non-invasive tear meniscus test (TMH), non-invasive break up time measurement (NIBUT), and meibography performed by using I.C.P. Ocular Surface Analyzer (SBM System, Turin, Italy). Results Significant improvements in OSDI symptom scores (p<0.0001), LLT (p<0.0001), and meibography (p<0.0001) were obtained at 10 weeks after bilateral periocular IPL therapy. COTE and ocular surface staining scores decreased by 59.72% and 57.14% respectively, while NIBUT and TMH increased by 47.34% and 22.16%, respectively. In parallel to the improvement in OSDI, LLT, and meibography, findings of acute blepharitis or blepharoconjunctivitis improved in slit-lamp examination. There were no adverse effects. Conclusion Serial IPL therapy improves the clinical signs and symptoms of moderate to severe acute blepharitis or blepharoconjunctivitis, meibomian gland morphology, and secretion quality.

Abstract
OBJECTIVES To evaluate clinical changes after intense pulsed light and meibomian gland expression (IPL/MGX) treatment in meibomian gland dysfunction (MGD) patients, and to identify ideal candidates, and the therapeutic window, for IPL/MGX. METHODS This retrospective study reviewed the medical records of 44 MGD patients (44 eyes). The IPL/MGX treatment was applied on the eyelids three times at intervals of 4 weeks. Age, sex, relevant ocular history, Standard Patient Evaluation of Eye Dryness (SPEED), Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), corneal fluorescein staining score (CFSS), meiboscore, meibomian gland loss score (MGLS), meibomian glands yielding secretion score (MGYSS), meibomian glands yielding clear secretion (MGYCS), and meibomian glands yielding liquid secretion (MGYLS) were analyzed. RESULTS Standard Patient Evaluation of Eye Dryness, OSDI, TBUT, CFSS, MGYSS, MGYLS, and MGYCS were significantly improved after three IPL/MGX treatments, but the meiboscore and MGLS remained unchanged. In patients who had better treatment outcomes (improvement in MGYSS >7), younger age (36.0, 22.5 vs. 53.0, 25.0 years; P=0.012), a longer TBUT (8.0, 4.5 vs. 6.0, 3.0 sec; P=0.010), better meiboscore (1.0, 0.5 vs. 2.0, 1.0; P=0.012), and less gland loss (19.8%, 20.3% vs. 41.1%, 30.2%; P=0.008) before IPL/MGX were noted. Sex, relevant ocular history, SPEED, OSDI, MGYSS, MGYLS, and MGYCS before IPL/MGX showed no significant differences between patients with an improvement in MGYSS >7 versus those with an improvement of ≤7. Meibomian glands yielding secretion score changes in patients who had a meiboscore of 0 to 1 and MGYSS of 0 before IPL/MGX (12.0, 10.0) were significantly higher than those who had a meiboscore of 2 to 3 and MGYSS of 0 (6.5, 9.3; P=0.031), or a meiboscore of 0 to 1 and MGYSS >0 (5.0, 11.5; P=0.041). CONCLUSIONS Improved dry eye symptoms, TBUT, corneal staining, and meibomian gland secretion were observed in MGD patients after IPL/MGX. Patients in the early stages of MGD maybe benefited most from IPL/MGX treatment.

Abstract
PURPOSE To study the efficacy and safety of intense pulsed light (IPL) in patients with meibomian gland dysfunction (MGD). METHODS This prospective randomized double-masked sham-controlled trial included 114 patients with MGD. Patients were randomized into the IPL or sham group. Either the IPL or sham procedure was performed on days 0, 15, and 45. Ocular Surface Disease Index (OSDI), visual analog scale, visual acuity, tear breakup time, meibum quality and expressibility, meibography grade, ocular surface staining, tear film lipid layer thickness, tear osmolarity, Schirmer test, tear interleukin-1 receptor agonist, and interleukin-6 levels were examined on days 0, 15, and 45 and at months 3 and 6. Subgroup analysis according to stage and the patient's compliance to conventional treatment were also analyzed. Any adverse events during the study were recorded. A multilevel mixed-effect linear regression model was used. P value less than 0.05 was considered statistically significant. RESULTS At 6 months, tear breakup time, meibum quality grades, expressibility grades, and OSDI were better in the IPL group (5.23 ± 2.91 vs. 3.11 ± 0.99 seconds, P < 0.001; 8.74 ± 4.74 vs. 13.19 ± 5.01, P < 0.001; 0.50 ± 0.67 vs. 1.12 ± 0.70, P < 0.001; 24.29 ± 16.92 vs. 32.71 ± 20.07, P < 0.05). OSDI, meibum quality, and expressibility in the IPL group began to improve at day 15 (P < 0.001), whereas the results in the sham group began to improve at day 45 (P < 0001). No adverse event occurred after IPL. CONCLUSIONS IPL is effective and safe for MGD treatment in all stages regardless of compliance.

Abstract
AIM To establish a new inflammatory animal model of meibomian gland dysfunction (MGD) in C57BL/6 mice. METHODS C57BL/6 mice were randomly divided into complete Freund's adjuvant (CFA) group (14 animals, 14 eyes), naphthazolin hydrochloride (NH) group (14 animals, 14 eyes) and control group (14 animals, 14 eyes). In CFA group, CFA was used in eyelid conjunctiva injection; in NH group, NH eye drops were used twice a day; control group was injected with equal dose of saline at the same time point and same site with animals in CFA group. The meibomian gland orifices score (MGOS) was evaluated on a scale of 0 to 3 in the middle five meibomian gland orifices of the upper and lower eyelid using slit lamp. After the successful induction of each animal model, intense pulsed light (IPL) was introduced on each mouse in CFA and NH group. Oil red O (ORO), hematoxylin and eosin (H&E) staining were performed before and after successful induction of CFA, NH and control group. RESULTS At 12wk after CFA injection, inflammatory cell infiltration and fiber necrosis was observed, with acinar density and duct dilatation significantly lower compared with control group. In NH group, the meibomian gland acini were relatively smaller and deformed compared with control group, the number of meibomian gland acini was also slightly lower. No inflammatory cell or fiber necrosis was observed in NH group. After three times of IPL treatment (5/10 mice in each group, and the other 5 mice served as non-IPL control), MGOS was significantly lower in IPL-treated mice in NH group (P<0.01). After three times of IPL treatment, the MGOS of NH group was significantly lower than that in the CFA group (P<0.01). CONCLUSION We develop a novel animal model that studies the role of inflammation in the development of MGD and IPL treatment. This model indicates that persistent inflammatory state may be the cause of MGD and weaken the therapeutic effect of IPL.

J Clin Med 2020; 9:jcm9113467. [PMID: 33126504 PMCID: PMC7693668 DOI: 10.3390/jcm9113467] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 10/25/2020] [Accepted: 10/26/2020] [Indexed: 01/01/2023] Open
Abstract
Aqueous-deficient dry eye (ADDE) and meibomian gland dysfunction (MGD) can be refractory to therapy. Intense pulsed light (IPL) was recently introduced as an effective treatment for MGD. We here evaluated the efficacy of IPL combined with MG expression (MGX) compared with MGX alone (n = 23 and 20, respectively) for patients with refractory ADDE with mild MGD at three sites. Symptom score, visual acuity (VA), noninvasive breakup time (NIBUT) and lipid layer thickness (LLT) of the tear film, lid margin abnormalities, fluorescein BUT (FBUT), fluorescein staining, tear meniscus height (TMH), meibum grade, meiboscore, and Schirmer's test value were assessed at baseline and 1 and 3 months after treatment. LLT, plugging, vascularity, FBUT and NIBUT were improved only in the IPL-MGX group at three months compared with baseline. All parameters with the exception of VA, meiboscore, TMH, Schirmer's test value were also improved in the IPL-MGX group compared with the control group at three months, as was VA in patients with central corneal epitheliopathy. Although IPL-MGX does not affect aqueous layer, the induced improvement in quality and quantity of the lipid layer may increase tear film stability and ameliorate symptoms not only for evaporative dry eye but for ADDE.

Abstract
The most prevalent type of meibomian gland dysfunction (MGD), which is obstructive, is the main cause of evaporative dry eye and is characterized by changes in the meibum composition and duct obstruction. Eyelid hygiene has usually been the most common clinical approach. However, alternative therapies for MGD are emerging on the market. Some warming and humidity devices have led to an improvement in the signs and symptoms in MGD patients. Likewise, eyelid massaging and cleaning devices are also beneficial for ocular signs and symptoms; however, patients usually need more than one session to maintain the therapeutic effect. Thermal pulsation has been reported to be more efficient than other strategies, and the effects can last up to 12 months. Moreover, intense pulsed light therapy has been demonstrated to improve ocular signs and symptoms alone and in combination with other therapies. Proper counseling of clinicians considering MGD status and patient compliance will help patients to undergo the adequate technique that best suits their condition.

Abstract
OBJECTIVES To evaluate recent studies on available therapies for meibomian gland dysfunction (MGD). METHODS A literature search on recent publications, within the last five years, concerning treatment options for MGD was performed. RESULTS A total of 35 articles were reviewed after curation by the authors for relevance. In general, all modalities of treatments were shown to have clinical efficacy in alleviating dry eye signs and symptoms, although the extent of improvement and persistency of outcomes varied between the different treatments. Evidence from published studies demonstrate that thermal pulsation produces the longest lasting effect per treatment, but it also incurs the highest per-treatment cost. Reusable methods for warm compress with lipid/semi-fluorinated alkane-containing eye drops are recommended as first-line treatment for mild-to-moderate dry eye patients, because this option is most technically feasible and cost-effective in clinical practice. Intense pulsed light (IPL) therapy and thermal pulsation may be suitable as second line for patients unresponsive to warm compress therapy; however, their respective limitations need to be considered. For refractory MGD with features of periductal fibrosis or severe blepharitis, supplementary treatment with meibomian gland probing or oral antibiotics may be used. CONCLUSIONS All eight forms of treatments, including self-applied eyelid warming, thermal pulsation, IPL, MG probing, antibiotics, lipid-containing eye drops, and perfluorohexyloctane, were effective against MGD, although with varying extent of clinical improvements. A better understanding on the mechanisms of actions may guide physicians to make better treatment decisions targeting the root causes.

Abstract
Meibomian gland dysfunction (MGD) is frequently encountered by eye care practitioners. It is characterised by obstruction of the Meibomian glands and/or alterations in the consistency of glandular secretions. At present, no definitive treatment exists for this condition. The present meta-analysis was performed to assess the efficacy of intense pulsed light (IPL) therapy in the management of MGD. Databases including EMBASE, PubMed, Cochrane Central, MEDLINE and Google Scholar were systematically searched to identify clinical trials that assessed the efficacy of IPL in the treatment of MGD. Outcome measures were described as the standardized mean difference (SMD). The fixed- or random-effects model was selected for analysis based on the Cochrane I2 values representing heterogeneity. Publication bias was visually inspected using Begg's funnel plot. Data were synthesized from four randomized controlled trials (RCTs) comprising 122 subjects in the IPL group and 120 subjects in the control group. Pooled analysis indicated no statistically significant difference in the Standard Patient Evaluation of Eye Dryness (SPEED) scores between the two groups [SMD -0.16 (95% CI, -0.41 to 0.10)] but a significant increase in Non-Invasive Tear Break-Up Time (NIBUT) scores in the IPL group (SMD, 0.90; 95% CI, 0.40-1.40). To conclude, the results of the present study did not provide any conclusive evidence for the efficacy of IPL therapy in the management of MGD. The analysis indicated that IPL therapy may result in an improvement of objective NIBUT scores but has no effect on subjective SPEED scores. Given the limited number of studies performed to date, there is a requirement for more well-designed prospective RCTs with a larger sample size to provide further evidence on the efficacy of IPL therapy.

Abstract
PURPOSE To review the published literature related to application of intense pulsed light (IPL) for treating meibomian gland dysfunction (MGD). METHODS The literature search included the PubMed database and used the keywords "Intense Pulsed Light and Meibomian Gland Dysfunction". RESULTS IPL is a new instrumental treatment modality for MGD. This treatment modality was originally developed for use in dermatology and was later adopted in ophthalmology for treating MGD. IPL therapy for MGD can improve tear film stability, meibomian gland functionality, as well as subjective feeling of ocular dryness. However, in the reviewed literature, there was great variability in patient selection, evaluation criteria, and treatment protocols and durations. CONCLUSION Numerous studies report that IPL is effective for treating MGD and a safe procedure. There is great potential for further improvements to the procedure, as large comparative studies employing different treatment modalities are lacking.
