RESUMO
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.

Many recent studies have demonstrated the efficacy of intense pulsed light (IPL) for the treatment of meibomian gland dysfunction (MGD); however, its effective treatment targets have not yet been elucidated. This study aimed to investigate the baseline characteristics associated with an improvement in symptoms after IPL treatment; to examine the course of change in inflammatory tear cytokines, meibomian gland function, and tear stability; and to investigate the correlation between cytokines and ocular surface parameters. Thirty participants underwent three sessions of IPL treatment. During each examination, tear film lipid layer interferometry, meibography, tear meniscus height measurement, tear sampling, and slit-lamp examination were performed, and the Ocular Surface Disease Index (OSDI) questionnaire was administered. Meibum quality, meibum expressibility, lid margin abnormality, tear film break-up time (TBUT), ocular surface staining, and the OSDI significantly improved after treatment. Poor meibum expressibility and short TBUT were associated with greater recovery in the OSDI after IPL. Tear levels of IL-4, IL-6, IL-10, IL-17A, and TNF-α decreased after IPL, and IL-6, and TNF-α were correlated with the improvement in meibum expressibility. Therefore, IPL treatment improved meibomian gland function, stabilized the tear film, and decreased ocular surface inflammation. Patients with obstructive MGD and tear instability were more likely to experience an improvement in ocular discomfort after IPL treatment.

PURPOSE: We aimed to determine the long-term effects of intense pulsed light (IPL) treatment in rosacea-associated meibomian gland dysfunction (MGD). METHODS: We enrolled 17 rosacea subjects with moderate and severe MGD who underwent four IPL sessions at 3-week intervals and were followed up for 12 months. The subjects underwent clinical examinations at baseline (first IPL) and at 3 (second), 6 (third), 9 (fourth), and 12 weeks, as well as 6 and 12 months, after baseline. Ocular surface parameters, including the Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), staining score, and noninvasive Keratograph tear break-up time (NIKBUT), as well as meibomian gland parameters, including the lid margin vascularity and meibum expressibility and quality, were evaluated. RESULTS: All ocular surface and meibomian gland parameters for all subjects exhibited significant changes from baseline to the final examination (Friedman, P < 0.050 for all). In particular, improvements in the lower lid margin vascularity, meibum expressibility and quality, and ocular symptoms persisted up to the final examination (Wilcoxon, P < 0.050 for all). However, the improvements of TBUT, staining score, and NIKBUT after IPL were not maintained at 6 and 12 months after baseline. CONCLUSIONS: In rosacea-associated MGD, four IPL treatments at 3-week intervals can improve long-term lid parameters and ocular symptoms without adverse effects.

The members of the Management and Therapy Subcommittee undertook an evidence-based review of current dry eye therapies and management options. Management options reviewed in detail included treatments for tear insufficiency and lid abnormalities, as well as anti-inflammatory medications, surgical approaches, dietary modifications, environmental considerations and complementary therapies. Following this extensive review it became clear that many of the treatments available for the management of dry eye disease lack the necessary Level 1 evidence to support their recommendation, often due to a lack of appropriate masking, randomization or controls and in some cases due to issues with selection bias or inadequate sample size. Reflecting on all available evidence, a staged management algorithm was derived that presents a step-wise approach to implementing the various management and therapeutic options according to disease severity. While this exercise indicated that differentiating between aqueous-deficient and evaporative dry eye disease was critical in selecting the most appropriate management strategy, it also highlighted challenges, based on the limited evidence currently available, in predicting relative benefits of specific management options, in managing the two dry eye disease subtypes. Further evidence is required to support the introduction, and continued use, of many of the treatment options currently available to manage dry eye disease, as well as to inform appropriate treatment starting points and understand treatment specificity in relation to dry eye disease subtype.

BACKGROUND: The aim was to investigate the efficacy of mechanical meibomian gland squeezing combined with eyelid scrubs and warm compresses in participants with moderate and severe meibomian gland dysfunction (MGD). METHODS: In this prospective, uncontrolled, open label, intervention study, 32 eyes of 32 participants with moderate and severe MGD were treated with mechanical squeezing of meibomian glands in combination with eyelid scrubs and warm compresses. We evaluated tear film break-up time (TBUT), corneal and conjunctival fluorescein staining scores, biomicroscopic examination of lid margins and meibomian glands, Ocular Surface Disease Index (OSDI) questionnaire and tear film lipid layer thickness determined via an interferometer before initiating treatment and after one month of treatment. RESULTS: There were significant improvements in TBUT, corneal and conjunctival fluorescein staining scores, lid margin abnormality, meibum quality and expressibility, OSDI and MGD stage after mechanical meibomian gland squeezing combined with eyelid scrubs and warm compresses (p < 0.001 for TBUT, corneal fluorescein staining scores, Dry Eye Workshop score, Oxford staining score, lid margin abnormality, meibum quality, expressibility, OSDI and MGD stage and p = 0.001 for conjunctival fluorescein staining scores). There were no significant differences in lipid layer thickness or interferometer-derived parameters before treatment and after one month of treatment. Palpebral conjunctival erosion detected after the squeezing treatment resolved spontaneously in all participants. CONCLUSIONS: Mechanical squeezing of meibomian glands combined with eyelid scrubs and warm compresses can provide clinical benefits without serious adverse events.

PURPOSE: To investigate the efficacy and safety of long-term maintenance treatment with tacrolimus ointment in chronic ocular graft-vs-host disease (GVHD) with ocular surface inflammation. DESIGN: A retrospective interventional consecutive case series. METHOD: Long-term maintenance treatment (≥6 months) with topical 0.02% tacrolimus ointment was applied to patients with chronic ocular GVHD with ocular surface inflammation (at least grade 2 inflammatory score). We evaluated the inflammatory score, steroid score and steroid use period of total duration, and numbers of inflammatory aggravations before and after tacrolimus treatment. The clinical outcomes were assessed by symptom score, ocular surface staining, Schirmer I test, tear break-up time (TBUT), and classification of chronic GVHD conjunctivitis at the initial and final examinations. RESULTS: Thirteen patients (24 eyes) were treated with tacrolimus ointment for up to 20 months (average 12.2 months). The ocular surface inflammatory score decreased from 2.8 to 0.6 (P = .001) within 2-8 weeks after starting tacrolimus ointment treatment. The numbers of inflammatory aggravation and the need for steroid treatment also decreased after initiating tacrolimus treatment. At the final follow-up, all patients reported improvement in clinical outcomes, compared to initial findings. Except for blurred vision or mild burning sensation, there were no reported side effects. CONCLUSION: Considering the chronic course of GVHD, long-term maintenance treatment with tacrolimus ointment could be useful and safe to locally treat ocular surface inflammation in chronic ocular GVHD.

PURPOSE: Retinoic acid (RA) is essential for epithelial differentiation and maintenance of the mucous phenotype. This study investigated the effect of RA on corneal epithelial differentiation and mucin expression in a primary human corneal limbal epithelial cell (HCLEC) culture model. METHODS: HCLECs were grown in RA-supplemented media at various concentrations (0, 10(-9) to 10(-6) M). Stratified HCLECs were examined using immunohistochemical or immunofluorescent staining for p63, ABCG2, CK3, CK19, and Western blotting for ABCG2 and CK12 to assess differentiation. Ultrastructural morphology was investigated using scanning and transmission electron microscopy. They were incubated with rose bengal dye to examine barrier function. The effects of RA on the expression of MUC1, -4, and -16 were analyzed by immunohistochemistry, quantitative real-time PCR and Western blot analysis. RESULTS: HCLEC grown without RA showed hyperkeratosis, whereas those grown with 10(-8) to 10(-7) M RA induced non-keratinized stratified epithelium with a normal appearance. Under these conditions, p63, ABCG2, CK3, CK19, MUC1, -4, and -16 staining patterns were similar to in vivo limbal epithelium. A higher concentration (10(-6) M) of RA resulted in abnormal differentiation. HCLECs grown with RA were tightly apposed and maintained intact barrier function against dye penetration. In addition, MUC1, -4, and -16 expressions were highly associated with RA concentrations. CONCLUSIONS: This study showed that cultured HCLEC could mimic physiologic and functional phenotypes by controlling RA concentrations in medium. Also, our results suggested modulating effect of RA on differentiation and mucin expression in corneal epithelium.
