    本研究调查了眼睑缝合近视(LSM)大鼠内在光敏性视网膜神经节细胞(ipRGC)和多巴胺能无长突细胞(DAC)的变化。
    通过缝合右眼4周在大鼠中诱导LSM。对整装视网膜中的ipRGC和DAC进行双重免疫荧光染色,以分析对照的密度和形态变化,LSM,和同伴的眼睛。采用实时定量PCR和Westernblotting检测相关基因和蛋白表达水平。
    眼睑缝合的眼睛引起了严重的近视,但是同伴的眼睛并没有不同的控制。在LSM大鼠视网膜的LSM和对眼中都观察到ipRGC密度降低,总体黑视素表达矛盾地增加,树突状珠子增大。相比之下,DAC的变化只发生在LSM的眼睛,随着DAC密度和酪氨酸羟化酶(TH)表达的降低,稀疏的树枝状过程,更少的静脉曲张。有趣的是,在LSM眼中,内丛状层(IPL)中ipRGC与DAC之间的接触以及垂体腺苷酸环化酶激活多肽(PACAP)和囊泡单胺转运蛋白2(VMAT2)mRNA的表达减少。
    LSM大鼠视网膜中的ipRGC和DAC在密度上经历了多次改变,形态学,和相关的分子表达。然而,单靠ipRGC的改变似乎不是近视发展所必需的,鉴于近视仅在眼睑缝合的眼睛中引起,他们不太可能独自推动DAC的变化。LSM眼中ipRGC和DAC之间的接触减少可能是它们之间信号传导受损的结构基础。PACAP和VMAT2,与ipRGC和DAC密切相关,可能通过复杂的机制在LSM中发挥重要作用。
    UNASSIGNED: This study investigates alterations in intrinsically photosensitive retinal ganglion cells (ipRGCs) and dopaminergic amacrine cells (DACs) in lid suture myopia (LSM) rats.
    UNASSIGNED: LSM was induced in rats by suturing the right eyes for 4 weeks. Double immunofluorescence staining of ipRGCs and DACs in whole-mount retinas was performed to analyze changes in the density and morphology of control, LSM, and fellow eyes. Real-time quantitative PCR and Western blotting were used to detect related genes and protein expression levels.
    UNASSIGNED: Significant myopia was induced in the lid-sutured eye, but the fellow eye was not different to control. Decreased ipRGC density with paradoxically increased overall melanopsin expression and enlarged dendritic beads was observed in both the LSM and fellow eyes of the LSM rat retinas. In contrast, DAC changes occurred only in the LSM eyes, with reduced DAC density and tyrosine hydroxylase (TH) expression, sparser dendritic processes, and fewer varicosities. Interestingly, contacts between ipRGCs and DACs in the inner plexiform layer (IPL) and the expression of pituitary adenylate cyclase-activating polypeptide (PACAP) and vesicular monoamine transporter protein 2 (VMAT2) mRNA were decreased in the LSM eyes.
    UNASSIGNED: The ipRGCs and DACs in LSM rat retinas undergo multiple alterations in density, morphology, and related molecule expressions. However, the ipRGC changes alone appear not to be required for the development of myopia, given that myopia is only induced in the lid-sutured eye, and they are unlikely alone to drive the DAC changes. Reduced contacts between ipRGCs and DACs in the LSM eyes may be the structural foundation for the impaired signaling between them. PACAP and VMAT2, strongly associated with ipRGCs and DACs, may play important roles in LSM through complex mechanisms.

    背景:高强度宏观和微观聚焦超声(HIFU)是治疗皮肤松弛的安全有效方法。然而,在眼睑上应用高强度聚焦超声能量与潜在的眼部并发症有关,包括外伤性白内障,虹膜睫状体炎,结膜出血,在其他人中。
    方法:一名40岁女性在双眼眼睑接受HIFU治疗后,左眼出现视力模糊,她的左远视力是20/66。检查显示左眼虹膜色素脱失和结膜出血。双眼在镜片中显示出多个白色条纹或t形混浊。
    结论:HIFU产生的过多超声能量可导致蛋白质变性,导致外伤性白内障等疾病,视力障碍,当应用于眼睛时,虹膜和结膜受伤。我们建议在眶周区域接受美容治疗的个体应高度了解可能的眼部副作用。
    BACKGROUND: High Intensity Macro and Micro Focused Ultrasound ( HIFU) is a safe and effective method for the treatment of skin laxity. However, the application of high-intensity focused ultrasound energy on eyelids has been associated with potential ocular complications including traumatic cataract, iridocyclitis, and conjunctival hemorrhage, among others.
    METHODS: A 40-year-old female developed blurred vision in her left eye after receiving HIFU treatment on binocular eyelids, and her left far vision was 20/66. The examination revealed left eye iris depigmentation and conjunctival hemorrhage. Both eyes exhibited multiple white streaking or tadpole-shaped opacities in the lenses.
    CONCLUSIONS: Excessive ultrasonic energy generated by HIFU can cause protein denaturation, leading to conditions such as traumatic cataract, visual impairment, injuries to the iris and conjunctiva when applied to the eyes. We recommend that individuals undergoing cosmetic treatment in the periorbital region should be highly aware of the possible ocular side effects.

    目的:这项研究描述了与人类下眼睑老化相关的外观变化,扎根于其解剖学基础。通过这些解剖表现进行下眼睑袋的量身定制方法。
    方法:从2017年1月至2023年1月,对137例患者进行了下眼睑眼睑成形术,20至60岁。这些患者根据眶周老化的外观分为3组,主要特征是下眼睑“袋”凸起的存在和位置。我们分析了每种类型的解剖结构的相应变化,其中包括一个弱化的纤维轨道支撑系统,肌肉张力降低,眼眶脂肪增加。根据患者的分类,采用量身定制的眼睑成形术技术进行治疗。这项研究中的所有患者的随访时间为1至12个月。有了病人的许可,照片和临床信息用于评估术前和术后结果。
    结果:我们的研究确定了下眼睑的3种形态。类型1在下眼睑的内侧和下方面呈现“气泡袋”。类型2具有双凸轮廓,由纤维结缔组织划分的单独的脂肪垫突出。3型表现出单个凸面,整个下眼睑的脂肪垫均匀突出。我们已经描绘了与每种形态类型相关的解剖学变化。以“重塑”和“恢复”为基础的方法,“手术治疗的目标是纤维支持组织,以改善下眼睑恢复的结果。无并发症发生。所有术后结果均达到了外科医生和患者的期望。
    结论:外科医生必须认识到纤维结缔组织的关键作用,包括弓形扩张,下斜肌筋膜,和保留韧带的口轮匝肌-并在手术过程中努力保持或加强这些结构。基于解剖学的手术方法将更有效和安全地抵抗面部老化过程。
    OBJECTIVE: This study characterizes the appearance changes associated with aging of the human lower eyelid, grounded in its anatomical basis. Tailored approaches to lower eyelid bag are performed by these anatomical manifestations.
    METHODS: From January 2017 to January 2023, lower eyelid blepharoplasty was performed on 137 patients, aged 20 to 60 years. These patients were divided into 3 groups according to the periorbital aging appearance, primarily characterized by the presence and location of the \"bag\" bulge of the lower eyelid. We analyzed the corresponding changes in anatomical structures for each type, which included a weakened fibrous orbital support system, reduced muscle tone, and increased orbital fat. Patients were treated with tailored blepharoplasty techniques according to their classification. All patients in this study ranged in follow-up from 1 to 12 months. With patients\' permit, photographs and clinical information were taken to evaluate the preoperative and postoperative outcome.
    RESULTS: Our study identified 3 morphologies of the lower eyelid. Type 1 presents a \"bubble bag\" in the medial and inferior aspect of the lower eyelid. Type 2 features a double convexity contour, with separate fat pad herniations demarcated by fibrous connective tissue. Type 3 exhibits a single convexity with a uniform herniation of fat pads across the entire lower eyelid. We have delineated the anatomical changes associated with each morphology type. With an approach grounded in \"remodeling\" and \"recovery,\" the surgical treatment targets the fibrous support tissue to improve the outcomes of lower eyelid rejuvenation. No complications occurred. All postoperative results reached both surgeon\'s and patient\'s expectations.
    CONCLUSIONS: Surgeons must recognize the pivotal role of fibrous connective tissues-including the arcuate expansion, fascia of the inferior oblique muscle, and the orbicularis retaining ligament-and endeavor to preserve or reinforce these structures during surgical procedures. An anatomically based surgical approach would more effectively and safely to resist the facial aging process.

    OBJECTIVE: To evaluate the surgical outcomes of a modified technique for treating congenital cilial entropion in children, which involves reducing tension step by step in the epicanthus and lower eyelid incision.
    METHODS: The observational group consisted of 153 pediatric patients (81 males and 72 females) who were treated using the modified technique, whereas the control group included 124 patients (68 males and 56 females) who were treated using the rotating suture surgery. All the participants were bilateral. Surgical outcomes were classified as good, fair, or poor, and the recurrence rate, scar condition, inferior eyelid position, and patient satisfaction were also assessed.
    RESULTS: The mean follow-up period was 9.13 ± 3.50 months (range: 3-14 months) for the observational group and 6.93 ± 4.51 months (range: 3-14 months) for the control group. In the observational group, surgical success with \"good\" outcomes was achieved in 300 eyes (98.04%), compared to 224 eyes (90.32%) in the control group. No recurrence occurred in the observational group, whereas the recurrence rate in the control group was 4.43%. Postoperative scar formation was mild in the observational group. The average scar score was 1.27 ± 0.96 in the observational group and 2.70 ± 0.99 in the control group, with a statistically significant difference (P < 0.001). Neither overcorrection nor postoperative ectropion was observed in both groups.
    CONCLUSIONS: The modified technique effectively corrected medial entropion and trichiasis in the lower eyelid, resulting in stable postoperative outcomes, mild scar formation, quick recovery, flexible eyelid motility, and stable ocular surface. Therefore, it can be widely applied to children with congenital entropion and trichiasis.

    OBJECTIVE: Dermatochalasis with lateral hooding and medial orbital fat loss are common signs of aging in the upper eyelid. Removing the excess skin in this area through infrabrow skin excision can effectively lift the loose skin of the upper eyelid and minimizes visible scarring. Additionally, we have identified three compartments of orbital fat prolapse based on orbital anatomy. Transferring volume from the lateral compartment to the intermediate region can flatten the lateral upper eyelid and create medial fullness, which ultimately rejuvenates the upper eyelid. This study presents an operative method for correcting age-related changes in the upper eyelid using this technique.
    METHODS: A total of 34 eyelids from 17 patients underwent a surgical procedure involving infrabrow skin excision, along with repositioning and lifting of lateral orbital fat. The inclusion criteria consisted of patients with moderate to severe upper eyelid dermatochalasis, coupled with middle fat loss and lateral hooding. To correct lateral hooding and restore midfacial fullness, lateral orbital fat was repositioned to an intermediate position, and the orbicularis oculi muscle was fold-sutured to the corrugator supercilii muscle.
    RESULTS: The mean age of the patients was 55.59 ± 3.20 years, with a range of 48 to 61 years. The mean follow-up period was 9.94 ± 1.35 months, ranging from 8 to 12 months. Patients were evaluated at 1-month, 3-month, and 6-month intervals. The Strasser system was used to evaluate the surgical outcomes at 3 months. All patients achieved good surgical outcomes, expressed through satisfactory cosmetic improvements, and improved visual field. The procedure effectively corrected lateral hooding and loss of middle orbital fat through infrabrow skin excision. No complications, such as wound dehiscence, lagophthalmos, noticeable scarring, ocular dyskinesia, or sensory changes, were observed.
    CONCLUSIONS: The combination of infrabrow skin excision, repositioning of lateral orbital fat, and lifting of the orbicularis oculi muscle effectively addresses moderate to severe dermatochalasis, lateral hooding, medial fat loss, and improves elasticity of the anterior wall of the upper lid in our patients. This procedure can produce satisfactory and long-lasting aesthetic results with an inconspicuous scar beneath the brow.

    评估扫频源光学相干断层扫描血管造影(SS-OCTA)评估眼睑边缘血管分布的能力。
    这个前景,横断面试验纳入125名参与者,包括15名对照受试者和110名睑板腺功能障碍(MGD)患者。使用SS-OCTA获得盖缘血流密度(LMBFD)。对125名参与者中的54名进行了LMBFD的可重复性评估,并对125名参与者中的23名进行了可重复性评估。在125名参与者中验证了LMBFD的有效性,他们被分为轻度(n=46),中等(n=42),根据裂隙灯照片中显示的眼睑边缘血管分布严重程度,以及严重组(n=37)。LMBFD与MG相关参数之间的相关性,如眼表疾病指数(OSDI),荧光素泪液破裂时间(FTBUT),角膜荧光素染色(CFS),眼睑边缘得分(LMS),和睑板腺可表达性(ME),对所有125名参与者进行了分析。
    在扫描面积为6mm×6mm(组内相关系数[ICC]重复性=0.905;ICC重复性=0.986)和扫描面积为9mm×9mm(ICC重复性=0.888;ICC重复性=0.988)的扫描模式下,重复性和重复性系数令人满意。轻度时LMBFD逐渐增加,中度,和严重组(P<0.001)。LMBFD与OSDI显著相关(r=0.290,P=0.001),FTBUT(r=-0.195,P=0.030),CFS(r=0.352,P<0.001),ME(r=0.191,P=0.033),LMS(r=0.370,P<0.001)。
    LMBFD可能是非侵入性的,可重复,可重复,为今后眼睑边缘血管的定量评价提供了有效的指标。
    我们证明了SS-OCTA具有评估MGD患者眼睑边缘血管分布的潜力,并指导临床未来的治疗策略。
    UNASSIGNED: To evaluate the ability of swept-source optical coherence tomography angiography (SS-OCTA) to assess lid margin vascularity.
    UNASSIGNED: This prospective, cross-sectional trial enrolled 125 participants, including 15 control subjects and 110 meibomian gland dysfunction (MGD) patients. Lid margin blood flow density (LMBFD) was obtained using SS-OCTA. LMBFD was assessed for repeatability in 54 of 125 participants and for reproducibility in 23 of 125 participants. The efficacy of LMBFD was validated in the 125 participants, who were divided into mild (n = 46), moderate (n = 42), and severe groups (n = 37) according to the lid margin vascularity severity shown in the slit-lamp photographs. Correlations between LMBFD and MG-related parameters, such as ocular surface disease index (OSDI), fluorescein tear break-up time (FTBUT), cornea fluorescein staining (CFS), lid margin score (LMS), and meibomian gland expressibility (ME), were analyzed in all 125 participants.
    UNASSIGNED: Repeatability and reproducibility coefficients were satisfactorily high in the scan mode with a scan area of 6 mm × 6 mm (intraclass correlation coefficient [ICC] repeatability = 0.905; ICC reproducibility = 0.986) and a scan area of 9 mm × 9 mm (ICC repeatability = 0.888; ICC reproducibility = 0.988). The LMBFD gradually increased in the mild, moderate, and severe groups (P < 0.001). LMBFD was significant correlated with OSDI (r = 0.290, P = 0.001), FTBUT (r = -0.195, P = 0.030), CFS (r = 0.352, P < 0.001), ME (r = 0.191, P = 0.033), and LMS (r = 0.370, P < 0.001).
    UNASSIGNED: LMBFD may be a noninvasive, repeatable, reproducible, and efficient index for the quantitative evaluation of eyelid margin vascularity in the future.
    UNASSIGNED: We demonstrated that SS-OCTA has the potential to evaluate the eyelid margin vascularity in MGD patients and guide future treatment strategies in clinics.
