睑板腺功能障碍发病机制及患病危险因素

睑板腺功能障碍(meibomian gland dysfunction,MGD)是一种慢性、弥漫性睑板腺异常,以睑板腺终末导管阻塞和(或)睑板腺分泌物的质量和数量改变为特征,可引起泪膜异常、眼部刺激症状、炎性反应以及眼表疾病.MGD发病主要与睑板腺分泌异常以及睑板腺终末导管阻塞有关,炎症是发病的关键.此外泪液特殊前蛋白和细胞凋亡在发病过程中也起到一定作用.     

强脉冲光综合治疗睑缘炎相关角结膜病变的短期疗效

目的：探讨强脉冲光(IPL)综合治疗睑缘炎相关角结膜病变(BKC)的短期疗效。

方法：选择2020-12/2021-12就诊于沧州爱尔眼科医院确诊为BKC的患者66例66眼(均选择病情严重的一眼进行研究),根据患者接受的临床治疗方式不同分为两组,对照组30例30眼,治疗组36例36眼,两组均在接受药物(给予0.1%氟米龙滴眼液、0.3%玻璃酸钠滴眼液、妥布霉素地塞米松眼膏点眼)治疗后1wk,以眼表状态作为基线水平,对照组继续进行药物治疗(给予0.1%氟米龙滴眼液、0.3%玻璃酸钠滴眼液点眼),治疗组在药物治疗基础上需在医院内定期进行IPL综合治疗(雾化熏蒸+IPL+睑板腺按摩+睑缘清洁+冷敷),每2wk 1次,共治疗4次。在药物治疗1wk后、IPL第1次治疗前(基线水平V1)和IPL第3次治疗前(V2)、IPL第4次治疗后2wk(V3)对两组患者进行随访,收集眼表疾病指数(OSDI)、裂隙灯下观察睑缘形态、睑板腺(MG)分泌物性质和分泌物排出难易程度、泪膜破裂时间(NIBUT)、眼红指数及角膜荧光素染色等数据,同时检查最佳矫正视力(BCVA)、眼压、眼前节及眼底,观察有无并发症的发生。

结果：两组患者治疗前OSDI、睑缘形态、MG分泌物性质和分泌物排出难易程度、NIBUT、眼表充血、角膜荧光素染色各项评分相比均无差异(P>0.05)。在V2、V3时,两组患者OSDI、睑缘形态、MG分泌物性质和分泌物排出难易程度、眼表充血分析、角膜荧光素染色各项评分均较治疗前(V1)下降,NIBUT较治疗前提高(均P<0.05),组间比较有差异(P<0.05),治疗组各项观察指标改善更明显。所有患者均未见明显并发症发生。

结论：IPL综合治疗可以减轻眼表炎症,改善睑板腺功能,可作为BKC物理治疗的新选择。

Hyperkeratinization and Proinflammatory Cytokine Expression in Meibomian Glands Induced by Staphylococcus aureus

PurposeThis exploratory study aimed to investigate the morphological and pathological alterations of the meibomian gland (MG) with the Staphylococcus aureus crude extracts (SACEs) treatment.MethodsMouse MG explants were cultured and differentiated with or without SACEs for 48 hours. Explant''s viability and cell death were determined by thiazolyl blue tetrazolium bromide (MTT) assay and TUNEL assay. MG morphology was observed by Hematoxylin and Eosin staining. Lipid droplet production was detected by Nile Red staining and LipidTox immunostaining. The pro-inflammatory cytokines were detected by ELISA. The relative gene and protein expression in MG explants was determined via quantitative RT-PCR, immunostaining, and immunoblotting. The components of the SACEs were analyzed by immunoblotting and silver staining.ResultsOur findings demonstrated that the SACEs treatment induced overexpression of keratin 1 (Krt1) in the ducts and acini of MG explants, accompanied by a decrease in viability and an increase in cell death in explants. Furthermore, the SACEs treatment dose-dependently increased the levels of TNF-α, IL-1β, and IL-6 in MG explants. The SACEs treatment induced activation of the nuclear factor kappa B (NF-κB) and AIM2 (absent in melanoma 2)/ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain) inflammasome signaling pathway in explants. Further investigation showed expression of the key adipogenesis-related molecule peroxisome proliferator-activated receptor γ was decreased after SACEs treatment. However, no change was found in the lipid synthesis of MG explants after treatment with the SACEs. Staphylococcal enterotoxins B (SEB) was detected in the SACEs. SEB induced the overexpression of Krt1 and IL-1β in ducts and acini of MG explants.ConclusionsOur findings confirm that Staphylococcus aureus induced hyperkeratinization and pro-inflammatory cytokines expression in MG explants ducts and acini. These effects might be mediated by SEB. Activation of the NF-κB and AIM2/ASC signaling pathway is involved in this process.     

A Newly Developed Video-Meibography System Featuring a Newly Designed Probe

Purpose

To demonstrate the usefulness of a video-meibography system featuring our newly designed probe.

Methods

This study utilized a newly designed probe featuring an obliquely inclined, T-shaped head containing 16 windows in the portion of the probe applied for emitting infrared light. The transilluminated structure of the meibomian gland is conducted to a highly sensitive, infrared charge-coupled device video camera and recorded digitally. The utility of the new probe was compared with the intraocular illumination probe traditionally used for meibography, both being applied to the eyelids of ten healthy volunteers and ten patients with meibomian gland dysfunction. The results were then analyzed.

Results

The newly designed probe facilitated eyelid eversion and transilluminated the meibomian gland structure effectively. Moreover, subjects experienced no irritation and only limited invasiveness when the new probe was applied.

Conclusions

Our meibography system featuring the newly designed probe provided greater ease of use, an improved visualization of the meibomian gland structure, and increased comfort for patients during the examination.?Jpn J Ophthalmol 2007;51:53–56 © Japanese Ophthalmological Society 2007     

睑板腺功能障碍患者睑缘形态与睑板腺形态学的相关性研究

目的 研究睑板腺功能障碍（MGD）患者睑缘形态与睑板腺形态的相关性。设计 横断面研究。研究对象 2019年北京同仁医院行Lipiflow热脉冲治疗前的MGD患者30例（30眼）。方法 通过眼前节照相技术和Oculus眼表分析仪拍摄睑缘和睑板腺,并依据睑缘形态、睑板腺主体部形态、睑板腺开口和分泌物性状进行分类。睑缘形态分为肥厚、充血、角化和变形;睑板腺主体部形态分为缺失、白色节段、导管膨胀、萎缩、扭曲和分叉;睑板腺开口形态分为圆形、脂帽、脂塞和脂栓。依上述形态进行评分,运用Spearman相关分析研究睑缘形态与睑板腺形态的相关性。主要指标 睑缘及睑板腺形态评分,睑缘及睑板腺形态学相关系数（r）。结果 睑板腺开口形态与分泌物性状之间呈正相关（r=0.590,P=0.001）,睑板腺白色节段与睑板腺开口形态呈正相关（r=0.439,P=0.015）;睑板腺萎缩和分叉与睑板腺的分泌物性状呈负相关（r=-0.349,-0.374;P=0.048,0.042）。在睑缘形态中,睑缘角化的评分与睑缘形态总评分呈正相关,且相关关系最强（r=0.842,P＝0.000）;睑缘角化与睑板腺开口形态改变呈正相关（r=0.517,P=0.003）。在睑板腺形态中,睑板腺白色节段评分与睑板腺总评分呈正相关,且相关关系最强（r=0.535,P＝0.002）。结论 MGD患者睑缘形态与睑板腺形态部分存在相关关系。睑板腺白色节段作为睑板腺主体部的形态评估指标更为合理;睑缘角化作为睑缘的形态评估指标更为合理,且睑缘角化与睑板腺开口的形态改变相关。（眼科, 2020, 29： 355-360）     

Noninvasive ocular surface analyzer as an adjunct in diagnosis and estimating prevalence of meibomian gland dysfunction: Hospital-based comparative study

Purpose:To assess the role of noninvasive ocular surface analyzer (OSA) in workup of meibomian gland dysfunction (MGD) and to estimate hospital-based prevalence of MGD using this objective device.Methods:The study recruited 113 consecutive participants attending the ophthalmology outpatient department of a tertiary care hospital. All participants were administered a symptom questionnaire. Participants underwent a comprehensive ocular examination, including slit-lamp biomicroscopy and meibomian gland expression. Lipid layer thickness (LLT), noninvasive tear breakup time (NIBUT), tear meniscus height (TMH), and meibomian gland loss (MGL) were assessed using OSA. The presence of either or both reduced/absent meibum secretion and cloudy to toothpaste-like secretion was diagnosed as MGD.Results:Prevalence of total MGD was 57.52% (95% confidence interval [95% CI]: 48.3%–66.8%) and that of symptomatic MGD was 42.5% (95% CI: 33.2%–51.7%). Prevalence of total and symptomatic MGD was highest in those aged ≥50 years (P < 0.001 and P = 0.004, respectively). Computer vision syndrome increased the odds of symptomatic MGD (odds ratio [OR]: 4.3). NIBUT and MGL significantly differed in MGD and non-MGD groups (P = 0.023 and P < 0.001, respectively). LLT significantly differed between asymptomatic and symptomatic cases (P = 0.033). MGL >25% increased the odds of having MGD (OR: 19.1). Significant negative correlations were observed between MGL and NIBUT (P = 0.04) and between MGL and LLT (P = 0.02). MGL demonstrated the highest diagnostic accuracy for MGD (AUC = 0.827, sensitivity = 75.4%, specificity = 85.4%, cut-off value: ≥26%).Conclusion:MGD is a common disorder in adults attending the ophthalmology outpatient services of a tertiary eye care hospital. Incorporating noninvasive OSA in clinical practice can aid in rapid and reliable measurements of MGD-related parameters.

In vivo confocal microscopy of meibomian glands and palpebral conjunctiva in vernal keratoconjunctivitis

Purpose:

To investigate the correlations between conjunctival inflammatory status and meibomian gland (MG) morphology in vernal keratoconjunctivitis (VKC) patients by using in vivo confocal microscopy (CM).

Materials and Methods:

Nineteen VKC patients (7 limbal, 7 tarsal, and 5 mixed forms) and 16 normal volunteers (controls) were enrolled. All subjects underwent CM scanning to obtain the images of upper palpebral conjunctiva and MGs. Inflammatory cell (IC) density in palpebral conjunctival epithelial and stromal layers, Langerhans cell (LC) density at lid margins and the stroma adjacent to the MG, and MG acinar unit density (MGAUD) were recorded. The longest and shortest diameters of MG acinar were measured. The Kruskal-Wallis test was used to compare the parameter differences whereas the Spearman''s rank correlation analysis was applied to determine their correlations.

Results:

Among all groups, no significant statistical differences were found in epithelial and stromal IC densities, mean values of MG acinar unit densities, or longest and shortest diameters. Both LC parameters in the tarsal-mixed groups were significantly higher than those in the limbal and control groups. All LC densities of VKC patients showed a positive correlation with MGAUD and shortest diameter.

Conclusions:

In VKC patients, the conjunctival inflammatory status could be associated with the MG status. In vivo CM is a noninvasive, efficient tool in the assessment of MG status and ocular surface.

结论：两种治疗方法治疗中度睑板腺功能障碍性干眼均有效,但重度睑板腺功能障碍性干眼需在睑板腺熏蒸按摩基础上联合强脉冲光治疗。     

A novel transillumination meibography device for in vivo imaging of mouse meibomian glands

PurposeWhile mouse models of dry eye disease (DED) have been developed, studies evaluating the role of the meibomian glands limited by the inability to temporally document changes. In this report we describe the development of a novel mouse transillumination meibography device and assess the ability of this device to detect age-related changes in the meibomian glands of young and old mice.MethodsThe mouse meibography device was comprised of a 3 mm wide right angle prism attached to broad spectrum light source by an optical fiber. Eyelids were then pulled over the prism using double tooth forceps and imaged using a stereomicroscope and low light level camera. Meibomian glands from four young and four old male, BALB/c mice were then imaged and analyzed using ImageJ.ResultsIn young mice, meibography documented the presence of 7–8 meibomian glands appearing as black and distinct eyelid structures with the length shorter in the lower eyelid compared to the upper eyelids. Eyelids of old mice showed apparent dropout of meibomian glands along with smaller and more irregularly shaped acini. The mean acini area of one meibomian gland was 0.088 ± 0.025 mm² in young mice and 0.080 ± 0.020 mm² in old mice (p = 0.564), but the Meibomian gland density was significantly lower in older mice (41.7 ± 6.4%, 27.3 ± 4.2%) (p = 0.021).ConclusionWe have developed an in vivo meibography device that may prove useful in sequentially documenting changes during development of meibomian gland dysfunction and following treatment.
