Abstract
PURPOSE To investigate the relationship between the kinematics of spontaneous blinks and the anterior area of the levator palpebrae superioris muscle in patients with Graves orbitopathy (GO). METHODS This is a case-control study. The authors measured the margin reflex distance of the upper eyelid (margin reflex distance 1), the kinematics of spontaneous blinks, and the anterior area of levator palpebrae superioris muscle in CT coronal scans of patients with Graves upper eyelid retraction (GO) and a control group. The eye with the greatest margin reflex distance 1 was selected for analysis in each group. RESULTS A total of 68 participants were included, with 36 in the GO group and 32 in the control group. In the GO group, the mean margin reflex distance 1 measured 6.5 mm, while in the control group, it was 3.9 mm. Almost all parameters related to the closing phase of spontaneous blinking activity, including amplitude, velocity, blinking rate, and interblink time, did not differ between the two groups. However, the effectiveness of the blink's amplitude (ratio of blink amplitude to margin reflex distance 1) and the main sequence (relationship between amplitude and velocity) were significantly reduced in the GO group compared with the control group. The area of the levator palpebrae superioris muscle was significantly larger in GO than in controls, with 71.4% of patients' muscles outside of the maximum range of the controls. CONCLUSIONS In patients with GO, there is a reduction in blinking effectiveness, also known as blink lagophthalmos, which is a factor in the common occurrence of ocular surface symptoms. The increase in velocity with amplitude is also reduced in GO.

Abstract
Purpose Currently, no solution exists to restore natural eyelid kinematics for patients with complete eyelid paralysis due to loss of function of both the levator palpebrae superioris and orbicularis oculi. These rare cases are prone to complications of chronic exposure keratopathy which may lead to corneal blindness. We hypothesized that magnetic force could be used to fully automate eyelid movement in these cases through the use of eyelid-attached magnets and a spectacle-mounted magnet driven by a programmable motor (motorized magnetic levator prosthesis [MMLP]). Methods To test this hypothesis and establish proof of concept, we performed a finite element analysis (FEA) for a prototype MMLP to check the eyelid-opening force generated by the device and verified the results with experimental measurements in a volunteer with total bidirectional eyelid paralysis. The subject was then fitted with a prototype to check the performance of the device and its success. Results With MMLP, eye opening was restored to near normal, and blinking was fully automated in close synchrony with the motor-driven polarity reversal, with full closure on the blink. The device was well tolerated, and the participant was pleased with the comfort and performance. Conclusions FEA simulation results conformed to the experimentally observed trend, further supporting the proof of concept and design parameters. This is the first viable approach in human patients with proof of concept for complete reanimation of a bidirectionally paretic eyelid. Further study is warranted to refine the prototype and determine the feasibility and safety of prolonged use. Translational Relevance This is first proof of concept for our device for total bidirectional eyelid paralysis.

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
Chronic mixed blepharitis accounts for 51.7% of all ophthalmic diseases. The use of laser Doppler flowmetry (LDF) in the diagnosis of this disease can help establish the initial manifestations of the inflammatory process in the eyelids, which is important for the prevention of possible complications - dry eye disease. PURPOSE This study was conducted to determine the sensitivity and specificity of the LDF method in the diagnosis of chronic mixed blepharitis based on the study of microcirculatory changes in the eyelid skin. MATERIAL AND METHODS The study included 23 patients with chronic mixed blepharitis (mean age 67±5.8 years) and 18 healthy volunteers (mean age 63±1.1 years). LDF was performed using the LAZMA MC-1 device. ROC analysis was used to determine sensitivity and specificity. RESULTS A typical disturbance of the eyelid skin microcirculation was revealed in chronic mixed blepharitis - ischemia - with inhibition of the intensity of the functioning of blood flow regulatory systems and moderate activation of the lymph flow. The sensitivity and specificity of the coefficient of variation (reflecting the vasomotor activity of microvessels) of blood flow was 71.43 and 71.43%, lymph flow - 65.71 and 80.00%; myogenic rhythms of blood flow - 83.33 and 85.71%, lymph flow - 66.67 and 71.43%; neurogenic rhythms of blood flow - 75.00 and 78.57%, lymph flow - 91.67 and 78.57%, respectively. CONCLUSION Laser Doppler flowmetry of the eyelid skin in combination with clinical, functional and instrumental research methods helped reveal with high sensitivity and specificity the eyelid damage in chronic mixed blepharitis. This method allows assessment of the condition of the eyelids in individuals without diseases of the anterior segment of the eye.

Abstract
Kimura disease (KD) is a rare benign chronic inflammatory disease that presents as a nodule mostly involving deep subcutaneous tissue of the head and neck region with frequent regional lymphadenopathy and peripheral blood eosinophilia. KD shares some clinical and histopathological similarity with angiolymphoid hyperplasia with eosinophilia (ALHE). Consequently, KD and ALHE were once considered variants of the same disease spectrum. We present here rare cases of Kimura disease and ALHE involving the eyelid and lacrimal gland and discuss their differential features.

Abstract
A 47-year-old woman with poorly controlled asthma and allergic rhinitis presented with recurrent episodes of bilateral upper eyelid swelling associated with forniceal conjunctival mass for the past 10 years. Routine blood investigations showed raised IgE levels and raised eosinophil counts. The diagnosis of Churg-Strauss syndrome (CSS) was made following biopsy of the conjunctival mass. The symptoms responded well to oral steroid treatment but recurred following cessation of the therapy. The patient was co-managed with a rheumatologist and the patient currently remains stable and is on oral Methotrexate and low dose oral steroids. Ocular involvement in CSS is unusual but this unique presentation of CSS was successfully managed, and the patient remains in remission.

Abstract
Workers in the dry-cleaning industry are exposed to organic solvents that may cause eye irritation and tear film changes. Objective To quantify changes in the ocular surface and tear film in dry cleaners exposed to organic solvents and associate these changes with ocular irritation as reported in a symptom questionnaire for dry eye diagnosis. Methods This was a case and control study in which the characteristics and eye-irritation symptoms were compared between two groups of 62 participants that were either exposed or not exposed to organic solvents. A general optometric examination and the following test were performed: lipid interferometry, Lissamine Green Stain, tear breakup time, Schirmer I, conjunctival impression cytology and the Donate dry eye symptoms questionnaire. Results Sixty-five percent of exposed workers obtained a higher score than 13 on the Donate dry eye symptoms questionnaire which indicated the presence of more irritation symptoms than those in the non- exposed group. A Chi-square analysis indicated the exposed group reported significantly higher incidences (P <0.005) for eye irritation symptoms of sandy sensation; tearing eyes sensation; foreign body sensation; tearing; dry eye; dryness; eyestrain and heavy eyelids. A Mann Whitney-U indicated greater severity only for symptoms relating to dry eye; sandy sensation; foreign body sensation, tearing; tearing eyes and dryness. There was a statistically significant difference (P <0.05) for Schirmer I; tear break up time; and the ocular surface assessed with Lissamine green staining and conjunctival impression cytology between groups. A reduction in the thickness of the lipid layer in the exposed group compared to the non-exposed group was observed. Surprisingly, clinical test outcomes were not significantly correlated with dry eye symptoms nor years of exposure. Conclusion Workers in the dry-cleaning industry exposed to organic solvents are associated with changes in ocular surface and tear film generating irritation symptoms commonly present in evaporative dry eye.

Abstract
PURPOSE To demonstrate in an animal model the feasibility of elevating the eyelid in a functionally useful manner by chronically stimulating the levator palpebrae superioris (LPS) muscle with an implanted electrode. METHODS Five rabbits were implanted with electrodes designed to stimulate the nerve innervating the LPS near its entry to the muscle. Bipolar platinum electrodes in a silicone rubber envelope with silicone-sleeved, PTFE-coated platinum lead wires were used to provide long-term stimulation with bipolar square-wave pulse trains of 0.18-0.80 mA and 200 Hz at a duty cycle of 8 seconds on and 2 seconds off. Explanted electrodes were examined for damage, and stimulated tissues were evaluated for abnormalities by light microscopy. RESULTS We achieved mean lid elevation of 1.6 mm, approaching the diameter of the light-adapted pupil, with 0.5 mA stimulus. Stimulus currents below 1.0 mA produced no signs of discomfort. Three animals with which we attempted daily stimulation, averaged 16.1 hours per week. Experiments lasted 22 weeks on average. Lid lifting with a well-implanted platinum electrodes was stable, with no apparent tissue or electrode damage after as long as 29.1 weeks. CONCLUSIONS Stable, functionally useful eyelid lifting was achieved with stimulation currents that caused no apparent discomfort or damage to muscles or nerves. A simple, discrete bipolar electrode was effective and survivable.

Abstract
PURPOSE To analyze the outcomes of patients who transitioned from a weight to a spring. METHODS Case series original investigation. Five consecutive patients undergoing "enhanced" palpebral spring insertion status post gold weight insertion were identified. Outcome measures included visual acuity, lagophthalmos, margin reflex distance 1, and corneal epithelial defects. Subjective outcomes included need for eye lubrication, closure and rapid blink, and symptoms of discomfort and dryness. This study was reviewed by an accredited Institutional Review Board (IRB) and granted exempt status according to federal regulations. RESULTS Mean visual acuity post weight versus spring was 20/200 (logMAR 1.0, Std Dev. -0.6) and 20/25 (logMAR 0.1, Std Dev. -0.1), respectively (p = 0.0214, CI 0.231 to 1.670). Mean lagophthalmos post weight (3.5 mm, Std Dev. -2.8) versus post spring (0.2 mm, Std Dev. -0.5). Margin reflex distance 1 improved by a mean of 1.4 mm (gold wt -0.6, Std Dev. -0.5/spring -2.0, Std Dev. -0.4) (p = 0.0016, CI -1.773 to -0.977). Superficial punctate keratopathy was present in all patients with weights and present in no patients post transition (p = 0.0079). Post transition, three of five patients rarely required lubrication and experienced a more satisfactory blink rate. CONCLUSION Patients with lagophthalmos due to cranial nerve seven palsy who have undergone gold weight placement but continue to exhibit objective and subjective corneal symptoms may have symptomatic improvement with the transition to a palpebral spring.

Abstract
BACKGROUND High placement of the lid crease is a common complication in upper eyelid surgery. Correction of the high crease by revision surgery is challenging and has not been well-reported. METHODS This is a retrospective interventional study of patients who underwent revision eyelid surgery with lowering of the lid crease from 2008 to 2016 at a tertiary institution. Main outcome measures were pretarsal show (PTS) distance, lid crease symmetry, margin reflex distance 1 (MRD1), and lid height symmetry. Lid crease symmetry was graded as symmetrical, mild asymmetry (PTS difference ≤ 0.5 mm), moderate asymmetry (PTS difference > 0.5 mm but ≤ 1 mm), or obvious asymmetry (PTS difference > 1 mm). Lid height symmetry was graded as symmetrical, mild asymmetry (MRD1 difference ≤ 1 mm), moderate asymmetry (MRD1 difference > 1 mm but ≤ 2 mm), or obvious asymmetry (MRD1 difference > 2 mm). RESULTS There were a total of 69 patients and 100 eyes. The majority (n = 42, 60.9%) of patients were females. The mean age was 38.3 ± 17.3 years, and mean follow-up was 16 months. Mean PTS decreased from 3.1 mm pre-surgery to 2.0 mm 2 years post-surgery. The proportion of patients with moderate or severe lid crease asymmetry decreased from 81.1% pre-surgery to 6.7% 2 years post-surgery. The mean MRD1 difference decreased from 1.54 mm pre-surgery to 0.23 mm 1 year post-surgery. The proportion of patients with moderate or severe lid height asymmetry improved from 64.5% preoperatively to 4.5% 1 year postoperatively. CONCLUSION Revision eyelid surgery to correct a high crease is a challenging procedure. We present a technique that is effective in correcting the high lid crease, while simultaneously improving the lid height and lid crease symmetry.

Abstract
We have been developing a facial wearable robot to support the eyelid movements of patients with facial paralysis, especially on one side of the face [1]. This robot has a mechanism for supporting eyelid movements, made from a soft material, which is called the eyelid gating mechanism (ELGM). The ELGM deforms by simple rotational actuation inputs and its deformation is customized to the eyelid movements. Therefore, this robot can provide non-invasive and gentle support for eyelid movements. We herein describe the design rule of the ELGM, and based on this, we conducted a deformation analysis with a non-linear finite element method. We verified the deformation trend from the results, and developed three prototypes based on this trend. Using these prototypes, we conducted a clinical study with facial paralysis patients to evaluate if the ELGM is capable of assisting in closing the eyelid.

Abstract
BACKGROUND Upper eyelid dermatochalasis often triggers frontalis hyperactivity in an effort to elevate the upper lids away from the visual axis. Similarly, prior neuromodulator treatment of the brow depressors may cause false elevation of the brows, diminishing the extent of preoperative brow ptosis or dermatochalasis. Studies have quantified postoperative brow ptosis and recurrent dermatochalasis following upper blepharoplasty, but a methodology to predict the postoperative brow position remains to be elucidated. OBJECTIVES The authors present our comprehensive perioperative protocol utilizing neuromodulators to optimize results of upper blepharoplasty and brow lift. METHODS In patients presenting with upper lid dermatochalasis and frontalis hyperactivity, who request upper blepharoplasty, the authors apply a neuromodulator treatment protocol. Patients with prior neuromodulator treatment of brow depressors wait four months after the last treatment to allow for product attrition. Two weeks prior to surgery, the authors treat the frontalis with 15 to 20 units of Botox Cosmetic. RESULTS From 2002 to 2016, the authors treated 521 patients (458 women, 63 men) with frontalis hyperactivity who presented for periorbital rejuvenation. This method has led to neither excessive resection of upper eyelid skin tissue nor lagophthalmos. Preoperatively, the authors have unveiled upper eyelid ptosis in 39 patients (31 women, 8 men) and brow ptosis in 131 patients (97 women, 34 men). CONCLUSIONS Brow position and frontalis hyperactivity should be taken into consideration during preoperative evaluation for upper blepharoplasty and brow lift. Routine preoperative treatment of the hyperactive frontalis with neuromodulator, along with attrition of prior neuromodulator in the brow depressors, reveals the true anatomic brow position to optimize surgical planning.

Abstract
Purpose. An association between the floppy eyelid syndrome and the obstructive sleep apnea syndrome (O.S.A.) has been reported. We studied eyelid tissue elasticity and other ophthalmologic findings in a large number of patients with sleep disorders. Material and Methods. Sixty-nine patients with sleep disorders were evaluated. Two thirds were found to have O.S.A., and one third was treated at night by nasal continuous positive airway pressure (nasal C.P.A.P.). Slit lamp examination, eyelid measurements and Schirmer test were performed. Results. Eyelid hyperlaxity was increased in patients with O.S.A. The floppy eyelid syndrome (associated papillary conjunctivitis), however, was rare. Associated corneal lesions were rare, and most patients were asymptomatic. In some cases, ocular irritation was due to air leaks from nasal C.P.A.P. A significant proportion of patients required treatment for primary open angle glaucoma. Conclusions. Our study of 69 patients found an association between O.S.A. and eyelid hyperlaxity.

Abstract
PURPOSE This study aimed to determine the relationship between lower eyelid epiblepharon and epicanthus in Korean children. METHODS We performed a retrospective review of the medical records and preoperative photographs of 119 patients. These patients were aged 18 years or younger who underwent lower lid epiblepharon repair from January 2010 to December 2012. We also included 119 age- and sex-matched controls. RESULTS The mean age of the patients was 5.7 years (range: 2-16 years) in both groups. The presence of an epicanthal fold was common in each group (98.3%). The inner intercanthal distance/interpupillary distance (IICD/IPD) ratio was significantly greater in the epiblepharon group than in the control group (mean: 0.70 vs 0.67, p<0.001), especially in those aged 5 years or older. The IICD/outer intercanthal distance ratio was also greater in the epiblepharon group than in the control group (mean: 0.48 vs 0.46, p<0.001). The IICD/IPD ratio decreased with growth in the control group, but it did not decrease with growth in the epiblepharon group. The configuration of the epicanthus, in which the upper skin fold formed a confluent fold with the lower eyelid, had a higher prevalence in the epiblepharon group than in the control group (p = 0.001), especially in those aged 5 years or older. CONCLUSION In early childhood (<5 years), the relationship between epicanthus and epiblepharon cannot be established because of the high prevalence of epicanthus in children with or without epiblepharon. In children aged ≥5 years, persistent epicanthus was related to severe epiblepharon formation requiring corrective surgery.

Abstract
Fatigue can lead to decreased work performance and poorer safety and health condition. Fatigue is ubiquitous in production and in life, while the research on it is mainly concentrated in the automotive driving, aircraft piloting and other fields, and it is insufficient to study on the fatigue of fixed-position staff. This paper puts forward a non-contact visual image method, which can monitor the extent of fatigue of fixed-position staff. Fatigue threshold used in judgment is obtained by processing the recorded data of visual images of the experimental subjects when fatiguing and by analyzing eye closure time, percentage of eyelid closure (PERCLOS) value, frequency and number of blinks. The results show that there is significant difference among the four indicators before and after experiment subjects undergo fatigue. The fatigue of experimental subjects is obvious when eye closure time is 3.5 s/min, PERCLOS value 6%, and blink frequency 0.4 times/s. This provides a reference for a wider range of detection of fatigue and a method for avoiding mistakes and accidents.

Abstract
BACKGROUND The classical levator resection (LR) technique for correcting ptosis involves separating the levator palpebrae superioris muscle (LPS) completely, which will inevitably collapse the muscle. The modified surgical method involving retention of the LPS suspensory system can allow for more contractility of the levator muscle and thus maximize protection of the eyelid structure. METHODS Ninety patients (132 eyelids) with different degrees of ptosis were enrolled. The same levator resection surgery whereby the suspensory system of the LPS is retained was performed in each patient. Postoperative outcome measures included the following: position of the upper eyelid margin, eyelid contour and plumpness, degree of scleral exposure, and exposure keratitis. Postoperative follow-up time points were 1 week, 1 month, and 6 months. RESULTS The positions of the eyelid upper margins were normal in all cases, and lagophthalmos only existed in severe cases in the early stage after surgery. Six months after surgery, 32% of the eyes had residual ptosis to varying degrees among severe cases, and the mild and moderate cases exhibited good surgical outcomes. The eyelids had appropriate closing functionality, and exposure keratitis was not observed in any case. Eyelid contour and plumpness was satisfactory in all patients. CONCLUSION Retaining the suspensory system of the LPS for LR with a modified surgery can protect the normal function and morphology of the eyelids. The surgery had a high success rate, especially for cases of mild and moderate ptosis. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
PURPOSE To determine if tangent visual fields gathered during assessment of superior visual field deficits caused by blepharoptosis and dermatochalasis offer good correlation to clinical exam in a time and cost efficient manner. METHODS Prospective, observational case series. Subjects included all patients referred to a single surgeon (CCN) who underwent surgical correction of blepharoptosis and/or dermatochalasis. Preoperatively and postoperatively, upper margin-to-reflex distances were assessed. Tangent visual fields were performed in a timed fashion and analyzed for degrees of intact vision in the vertical meridian and degrees squared of area under the curve. Data were compared by Student t-tests and Pearson correlation coefficients. RESULTS Mean preoperative superior visual fields with the eyelid in the natural position measured 8° in the vertical meridian. Measurements in the vertical meridian and area under the curve showed excellent correlation (r = 0.87). Patients with ptosis showed strong correlation between margin-to-reflex distance and superior visual fields. Patients completed field testing faster than reported times for automated or Goldmann testing. Finally, tangent screens were the least expensive type of equipment to purchase. CONCLUSIONS Tangent visual fields are a rapid and inexpensive way to test for functional loss of superior visual field in patients with upper eyelid malposition. Our data revealed potential differences between tangent screen results and published results for automated or Goldmann visual field testing which warrants further studies.

Abstract
Both the Müller muscle-conjunctiva resection (MMCR) and levator advancement (LA) procedures can be used to manage ptosis in patients with good levator function. The aim of this article is to evaluate the efficacy and cosmetic outcomes of the two procedures. The clinical records of 29 consecutive eyelids of 26 patients undergoing MMCR and 30 eyelids of 23 patients undergoing LA were analysed. Eleven (42%) in the LA group and 9 (39%) in the MMCR group were male. The preoperative eyelid measurements were significantly different in the LA compared to the MMCR groups, in terms of palpebral aperture (PA) (6.3 vs 7.4, p = 0.01), marginal reflex distance 1 (MRD1) (-0.1 vs 1.5, p < 0.001) and levator function (LF) (12.1 vs 13.4, p = 0.03). The MRD1 1 month post-surgery was slightly less in the LA group compared to the MMCR group (2.6 vs 3.18 mm, p = 0.047) but not significantly different at months 3 and 6. The final change in MRD1 was significantly higher in the LA group (2.93 vs 1.76, p = 0.004). The MMCR group had a lower incidence of lid contour abnormalities (0% vs 20%, p = 0.01) and overcorrection (0% vs 13%, p = 0.04). There was no statistically significant difference in the rates of undercorrection in either group. Both the MMCR as well as LA procedures are effective for mild to moderate ptosis in patients with good levator function. Patients undergoing MMCR had higher success rates, better preservation of the natural lid contour, and a lower incidence of overcorrection than patients undergoing LA.

Abstract
This article evaluates the effects of Muller's muscle-conjunctival resection (MMCR) on ocular surface scores and dry eye symptoms. Forty-six patients were enrolled in the study. Eighteen underwent bilateral upper eyelid skin excision with MMCR and 28 underwent bilateral upper eyelid skin-only excision (control group). The Salisbury Eye Evaluation Questionnaire and an ocular surface evaluation protocol consisting of Schirmer's test, tear break-up time (TBUT), fluorescein and rose bengal corneal staining were performed during the pre-operative consultation and on postoperative days 7, 30, and 90. Improvement in symptoms questionnaire scores from baseline was observed on postoperative day 90 in the blepharoplasty plus MMCR group. There was no change in questionnaire scores in patients who underwent blepharoplasty alone. No between-group difference in Schirmer's test, TBUT, or fluorescein and rose bengal staining was found at any time point. In the blepharoplasty-only (control group), the fluorescein staining score was reduced on postoperative day 30 as compared to baseline, but not on day 90. In this sample, addition of MMCR to upper eyelid blepharoplasty did not worsen ocular surface scores or dry eye symptoms.

Abstract
Ptosis of the eyelids is a common condition with a myriad of causes. Its management depends on the underlying cause, which can be challenging to diagnose in some cases. Current diagnosis methods include serum antibodies, tensilon test, and electromyography (EMG). Each has its own set of limitations such as invasiveness and lack of sensitivity. To overcome these limitations, we have developed a Portable Realtime Infrared Lids, Iris and Blink (PRILIB) monitoring system, with a long-term goal to improve clinical diagnosis of ptosis. In this paper, we present the algorithms to detect and analyze eye parameters and report experimental results. From experiments conducted on normal volunteers and myasthenic patients, we found 1. Partial blinks happen when Ocular Myasthenia Gravis (OMG) patients are tired or engaged in an activity; 2. Blink rate is significantly higher for OMG patients due to failure to blink fully; 3. There are noticeably more fluctuations of palpebral aperture of OMG patients due to rising and falling of the eyelid height. These experimental findings suggest new diagnostic features for OMG patients and have implications for disease management.

Abstract
Feingold syndrome (FS) is an autosomal dominant disorder characterized by microcephaly, short stature, digital anomalies, esophageal/duodenal atresia, facial dysmorphism, and various learning disabilities. Heterozygous deletion of the miR-17-92 cluster is responsible for a subset of FS (Feingold syndrome type 2, FS2), and the developmental abnormalities that characterize this disorder are partially recapitulated in mice that harbor a heterozygous deletion of this cluster (miR-17-92∆/+ mice). Although Feingold patients develop a wide array of learning disabilities, no scientific description of learning/cognitive disabilities, intellectual deficiency, and brain alterations have been described in humans and animal models of FS2. The aim of this study was to draw a behavioral profile, during development and in adulthood, of miR-17-92∆/+ mice, a genetic mouse model of FS2. Moreover, dopamine, norepinephrine and serotonin tissue levels in the medial prefrontal cortex (mpFC), and Hippocampus (Hip) of miR-17-92∆/+ mice were analyzed.Our data showed decreased body growth and reduced vocalization during development. Moreover, selective deficits in spatial ability, social novelty recognition and memory span were evident in adult miR-17-92∆/+ mice compared with healthy controls (WT). Finally, we found altered dopamine as well as serotonin tissue levels, in the mpFC and Hip, respectively, of miR-17-92∆/+ in comparison with WT mice, thus suggesting a possible link between cognitive deficits and altered brain neurotransmission.

Abstract
PURPOSE Progressive myoclonic epilepsies (PME) include a heterogeneous group of disorders. The brainstem is involved in these disorders, as demonstrated by neuroimaging and autopsy studies. The blink reflex (BR) is characteristically elicited after supraorbital electrical stimulation. The BR has two components, an ipsilateral R1 and bilateral R2 (R2 and R2c). The central generator of the BR is the brainstem. In this study, we aimed to investigate the functional status of the brainstem using the BR in PME cases with different etiological factors. METHODS We prospectively included 17 patients with a diagnosis of PME (8 male, 47.1%) who were examined between June 2009 and June 2012. For comparison, we included 41 healthy volunteers (18 male 43.9%) who did not have any neurological or systemic diseases. We recorded responses bilaterally over the orbicularis oculi muscles after supraorbital stimulation in all participants. RESULTS The R1 and R2 components of the BR were obtained in all healthy subjects with normal latencies, whereas abnormalities in the R2 and R2c components were observed at significantly higher rates in the PME patients. The mean latencies of the bilateral R2 and R2c components were significantly prolonged, and the amplitudes were diminished in the PME patients. Disease duration and the use of multiple antiepileptic drugs were related to abnormal R2s. CONCLUSION The abnormalities of the R2 and R2c components of the BR confirmed the inhibition of the reticular formation. The findings are probably related to disease processes and partially due to the use of multiple antiepileptic drugs.

Abstract
PURPOSE Frontalis suspension is the treatment of choice for severe blepharoptosis with poor levator function. Several materials are available for this purpose. Autologous fascia lata is considered best among naturally occurring materials; however, it may not be possible to harvest fascia lata in young children. Among various synthetic materials, silicone has been used frequently and has given good results. METHODS This is a retrospective analysis of patients operated on from September 2008 to August 2013. All of these patients underwent silicone rod frontalis suspension for severe blepharoptosis with poor levator function and completed a minimum of 6 months of follow-up. RESULTS There were 38 eyes of 25 patients with ages ranging from 3 to 21 years (average: 10.68 ± 6.26 years). Of these 25 patients, 10 had blepharophimosis syndrome, 10 had congenital ptosis, 3 had third nerve palsy, 1 had double elevator palsy, and 1 had post-levator resection. Good cosmetic correction was achieved in 34 eyes (89.4%) after a mean follow-up of 18 months (range: 6 to 60 months). Complications observed included significant eyelid lag and lagophthalmos (5 eyes), undercorrection (4 eyes), suture granuloma (3 eyes), sling exposure at forehead incision (3 eyes), bilateral chronic eyelid edema (1 patient), and late recurrence of ptosis (1 eye). CONCLUSIONS Silicone is a safe material for frontalis suspension in patients with severe ptosis; however, recurrence, granuloma formation, sling exposure, and chronic inflammation can occur with use of silicone rod.

Abstract
We herein report three cases of Parkinson's disease associated with difficulty in eyelid opening, referred to as apraxia of eyelid opening (AEO), which improved after aripiprazole treatment. In case 1, aripiprazole was administered as a psychiatric treatment. It proved to be effective in AEO with blepharospasm. In case 2 and case 3, the patients experienced AEO without blepharospasm, and a significant improvement was observed after aripiprazole treatment. In this study, the aripiprazole dosage ranged between 3 and 9 mg/day. This is the first report of aripiprazole as a potentially effective treatment for AEO in Parkinson's disease.

Abstract
PURPOSE To compare open and closed methods of the frontalis suspension operation with a silicone rod in the treatment of congenital blepharoptosis. METHODS Forty-four cases with unilateral or bilateral congenital ptosis with a poor levator function of < 4 mm were divided randomly into two groups. Each group underwent an eyelid crease incision operation (open) or a supralash stab incision (closed). Ptosis was measured by the difference between the upper eyelid margin reflex distance (MRD) of the affected eyelids of the unilateral and bilateral cases. Frequent follow-up examinations were performed up to 12 months post-surgery. RESULTS Associated ophthalmologic findings showed that amblyopia, strabismus, wound discharge and knot dehiscence problems were present in 36.6%, 27.3%, 8.5% and 8.5% of the patients, respectively. There was no significant difference between the abovementioned associated ophthalmic findings of the two operative methods studied (P = 0.37). The difference in the surgical methods and MRD 3, 6 and 12 months after operation did not reach statistical significance. Similar results for good MRD (3 < MRD < 5) were found in closed (54.5%, 12/22) and open (54.5%, 12/22) methods, while 40.9% (9/22) and 45.5% (10/22) of cases were attributed to the under correction group in the closed and open methods, respectively. In bilaterally operated cases, MRD was more symmetrical than in unilaterally operated eyes. The symmetry of MRD and the eyelid crease was more prevalent in the open technique group. CONCLUSIONS The frontalis sling operation using a silicone rod exhibited better results, in terms of symmetry, in the open technique in comparison to the closed method.

Abstract
Over 200 patients with acoustic neuromas and over 100 patients with posterior cranial fossa meningiomas are annually operated on at the N.N. Burdenko Neurosurgical Institute. Intraoperative monitoring of the facial nerve function is used in most patients with tumors of the posterior cranial fossa to identify the facial nerve in the surgical wound. If the anatomical integrity of the facial nerve in the cranial cavity cannot be retained, facial nerve repair is performed to restore the facial muscle function. Intraoperative electrical stimulation of the facial nerve has a great prognostic significance to evaluate the dynamics of lagophthalmos in the late postoperative period and to select the proper method for lagophthalmos correction. When the facial nerve was reinnervated by the descending branch or trunk of the hypoglossal nerve, sufficient eyelid closure was observed only in 3 patients out of 17.

Abstract
AIMS To report our experience using hyaluronic acid gel injection in the lower eyelid to treat cicatricial ectropion. METHODS Clinical records and literature review. RESULTS Between November 2009 and June 2011, 12 lower eyelids of 11 patients with cicatricial ectropion were treated with hyaluronic acid gel. All 11 patients demonstrated improvement in the eyelid position after treatment but only 3 patients (27.3%) experimented total correction after injection. Although the correction was partial in the majority of the patients, the signs and symptoms associated with conjunctival and corneal exposure improved in all patients. Seven patients (63.7%) developed irregular fullness which resolved over time, but in 4 patients (36.3%) fullness persisted for one year. CONCLUSIONS In our experience, hyaluronic acid gel is a nonsurgical, minimally invasive and safe technique that improves cicatricial ectropion, but with a poor cosmetic result that limits its use. This treatment could be considered only in patients who decline surgery or are poor surgical candidates, as the aesthetic result would not be acceptable to many.

Abstract
BACKGROUND Although Hering's law has significant importance in the planning and outcomes of eyelid surgery, it has not been applied in all cases of ptosis. OBJECTIVES The authors evaluate whether cases of unilateral congenital ptosis require surgery on the contralateral eyelid, in keeping with Hering's law. METHODS The records of 35 consecutive patients with unilateral congenital ptosis who had surgical repair between 2007 and 2012 were retrospectively analyzed. All patients underwent either levator resection or frontalis sling surgery. Preoperative and postoperative clinical documents and photographs were evaluated for each case, including preoperative Hering's dependence and postoperative measurements of the change in position of the nonoperated eyelid. RESULTS There were 19 women and 16 men, and the average patient age was 9.7 ± 10 years. The mean preoperative levator function and marginal reflex distance were 6.7 ± 4.7 mm and 0.3 ± 0.47 mm, respectively. There were significant differences in age, preoperative levator function, and marginal reflex distance between patients who underwent levator resection and those who had frontalis sling surgery. In all patients, the preoperative Hering's dependence of eyelid position did not show any decrease, and the position of the contralateral eyelid postoperatively did not differ from the baseline position. CONCLUSIONS This research shows that Hering's law does not apply to cases of congenital ptosis. This is likely due to the fibrotic levator palpebrae muscle and its special innervations. Thus, it is not necessary to perform levator resection or a frontalis sling operation on the unaffected eyelid.

Abstract
Sensation over the face was estimated using the Semmes-Weinstein's monofilament (target force 0-05 gms) in a cohort of multi-bacillary (MB) patients whose clinical and ocular characteristics were available at the time of leprosy diagnosis. Among the 190 MB patients examined, 56 (30%) had areas of sensory impairment somewhere on the face and 43 (23%) had sensory deficit over the lids and/or the malar area. Lagophthalmos (adjusted OR 8.96, 95% CI 0.96-83.50), Type 1 reaction (aOR 2.47, 95% CI 1.11-5-52), history of reactions (aOR 6.36, 95% CI 2.40-16.85) and glove and stocking anaesthesia (aOR 3.49, 95% CI 1-40-8.70) were associated with impaired facial sensation. Hypoesthesia restricted to areas over the lids and/or malar area showed a stronger association with lagophthalmos (aOR 17.5, 95% CI 1.98-154.36). Loss of facial sensation appears to be associated with lagophthalmos in MB patients.

Abstract
Patients suffering from facial paralysis are on the hazard of disfigurement and loss of vision due to loss of blink function. Functional-electrical stimulation (FES) is one possible way of restoring blink and other functions in these patients. A blink restoration system for uni-lateral facial paralyzed patients is described in this paper. The system achieves restoration of synchronized blink through processing the myoelectric signal of orbicularis oculi at the normal side in real-time as the trigger to stimulate the paralyzed eyelid. Design issues are discussed, including EMG processing, stimulating strategies and real-time artifact blanking. Two artifact removal approaches based on sample and hold and digital filtering technique are proposed and implemented. Finally, the whole system has been verified on rabbit models.

Abstract
BACKGROUND Volume loss in the upper and lower eyelids and in the malar area is now considered a major component of periorbital aging. As classical resection blepharoplasty does not address this loss, filling procedures are becoming increasingly common. OBJECTIVES The authors present their experience with periorbital fat grafting in conjunction with routine blepharoplasty to address periorbital aging. METHODS Outcomes were retrospectively reviewed for 500 consecutive patients who underwent blepharoplasty in conjunction with the authors' periorbital augmentation technique from January 2008 to September 2011. The augmentation technique was a fine particle fat (microfat) grafting procedure that involved the use of small-diameter cannulae for transfer of autologous fat to the medial part of the upper eyelid, the orbitomalar groove, and the malar area. RESULTS Clinical evaluation and review of patient photographs revealed favorable, natural-looking, and long-lasting improvement of the treated areas. Shortcomings of classical resection blepharoplasty, such as hollowing of the upper eyelids, incomplete blending of the eyelid-cheek junction, and persistent deflation of the midface, were avoided; the full and crisp aspect of the upper and lower eyelids seen at a younger age was regained; and the technique was not associated with the complications seen in an earlier patient series. No major complications occurred. Minor complications included bruising and swelling. CONCLUSIONS Augmentation of the upper and lower eyelids through microfat grafting can be a useful alternative to existing blepharoplasty techniques. This study documents very natural and pleasing results that avoid the shortcomings of classical resection. Microfat grafting appears to be a valuable and safe alternative to complicated, difficult, and potentially dangerous eyelid and midface rejuvenation techniques.

Abstract
Apraxia of lid opening (ALO) is a non-paralytic inability to open the eyes or sustain lid elevation at will. The exact pathophysiological mechanisms underlying the syndrome are still unknown. ALO has been reported in patients with Parkinson's disease (PD) after subthalamic nucleus (STN) deep brain stimulation (DBS), suggesting a possible involvement of the basal ganglia. We aimed to assess the effects of varying STN stimulation voltage on ALO in PD patients. Seven out of 14 PD patients with bilateral STN stimulation consecutively seen in our centre presented with ALO. We progressively increased voltage on each STN, using either 130 Hz (high-frequency stimulation, HFS) or 2 or 3 Hz (low-frequency stimulation, LFS). In five patients, HFS induced ALO time-locked to stimulation in 7 out of 10 STNs at a voltage higher than that used for chronic stimulation. LFS induced myoclonus in the pretarsal orbicularis oculi muscle (pOOm) with a rhythm synchronous to the frequency. In the other two patients with ALO already present at the time of the study, HFS improved ALO in 3 out of 4 STNs. ALO recurred within minutes of stimulation arrest. Our findings show that STN-DBS can have opposite effects on ALO. On the one hand, ALO is thought to be a corticobulbar side effect due to lateral current spreading from the STN, in which case it is necessary to use voltages below the ALO-inducing threshold. On the other hand, ALO may be considered a form of off-phase focal dystonia possibly improved by increasing the stimulation voltages.

Abstract
A complex of measures for lid hygiene in ocular surface disease is developed. These measures together with tear substitution and antibacterial treatment were revealed to result in elimination of blepharoconjunctivitis and dry eye signs, recovery of tear film and long-time remission, that significantly improved patient's life quality. When using this complex of measures meibomian glands are not damaged and their anatomy and functions are completely preserved. Lid hygiene affects all glands, there is no pain and no local anesthesia needed, normal tear film is formed

Abstract
We report two patients with unilateral vertical retraction syndrome. Magnetic resonance imaging (MRI) of the orbits of the two cases showed similar size and location of the orbital structure, but with dramatically different strabismus type. MRI sagittal reconstruction of the orbits suggested that abnormal muscle tissue arised from the inferior rectus, which might be associated with retraction and narrowing of the palpebral fissure and atypical strabismus as well.

Abstract
OBJECTIVES Temporalis Muscle Transfer (TMT) is a surgical technique used to correct lagophthalmos in leprosy patients. We have evaluated the degree of success of TMT in achieving full lid closure, which is important in preventing damage to the cornea. SUBJECTS AND METHODS A retrospective study was carried out on 69 patients who had TMT done, at one centre, on 101 eyes during the period of 1998-2009. Lid gaps on direct gaze and with both gentle and forced closure, as well as voluntary muscle testing of eye lid closure, were assessed using standard measuring techniques by a qualified physiotherapist. Associated problems due to lagophthalmos were recorded both pre- and post- operatively. Data were abstracted on to a special proforma and subjected to statistical analysis using SPSS. RESULTS On completion of post-operative physiotherapy, 85% of the eyes could achieve full lid closure with no measurable gap. The mean (SD) lid gap on forced closure was 48 (2.8) mm pre-operatively and 0.2 (0.5) mm at the end of the in-patient stay. The mean (SD) lid gap on gentle closure was 7.9 (2.6) mm preoperatively and 2.4 (1.8) mm post-operatively. The mean (SD) vertical inter-palpebral distance, during straight gaze, was reduced from 12.6 (1.6) pre-operatively to 9.8 (1.2) postoperatively. Exposure keratitis cleared in 16 of 27 eyes (60%) and Epiphora cleared or improved in 31 eyes. CONCLUSIONS It is concluded that the TMT is a successful option (cosmetically and functionally) for correction of lagophthalmos.

Abstract
Authors took clinical case of primary surgical reconstruction in total eyelid avulsion as an example to discuss possible mistakes of surgical technique and implant choice. Besides, prognosis for different eyelid tissues retention in total eyelid avulsion and subsequent reconstruction are analyzed. Laser Doppler flowmetry is a method for dynamic evaluation of retention and prognosis of autotissue rejection, it clearly demonstrates decrease of microcirculation in the sites of worse tissue retention.

Abstract
A 62-year-old woman presented with difficulty in speaking and difficulty in opening her eyes. A neurological examination revealed progressive nonfluent aphasia (PNFA), apraxia of eyelid opening, supranuclear vertical gaze palsy, and mild asymmetric rigidity. The diagnosis was difficult to establish because of unusual clinical features, and progressive supranuclear palsy (PSP) was considered. The results from recent studies suggest a positive association between PNFA and a diagnosis of corticobasal degeneration (CBD) or PSP, even in mild parkinsonism cases. The overlapping clinical, genetic, and pathological features of CBD and PSP have also been recently recognized. However, in Japan, there have been few reports evaluating the clinical features of CBD or PSP accompanied by primary progressive aphasia. We report the case of our patient and compare the clinical features of our patient with those of Japanese patients with CBD or PSP accompanied by primary progressive aphasia; moreover we discuss clues that can lead to the correct clinical diagnosis of patients with primary progressive aphasia and parkinsonism comorbidities.

Abstract
We report the case of a 76-year-old man with apraxia of eyelid opening (AEO) and amyotrophic lateral sclerosis with dementia (ALS-D)/frontotemporal lobar degeneration with motor neuron disease (FTLD-MND). The initial symptom was AEO. Neurological examination revealed mainly bulbar symptoms with a neurogenic pattern on needle electromyograms of the tongue muscles and the biceps muscles. Furthermore, he developed severe dementia with frontal lobe dysfunction and progressive non-fluent aphasia. Brain magnetic resonance imaging revealed severe cerebral atrophy and leukoaraiosis in the bilateral frontal lobes and the anterior part of the bilateral temporal lobes; brain 99mTc ethyl cysteinate dimer single photon emission computed tomography (ECD SPECT) showed hypoperfusion in the same areas. The patient showed improvement in stereotyped behavior and AEO after treatment with 50 mg/day of fluvoxamine maleate (the initial dose was 25 mg/day). Because serotonin receptors are markedly reduced in the frontal and temporal cortexes of patients with FTLD, we considered that dysfunction of the serotonergic system in the frontotemporal lobe caused AEO. Considering the findings of this case along with those of previous reports, we propose that there is a relatively homogeneous development of ALS-D/FTLD-MND with AEO.

Abstract
Treating unilateral ptosis can be challenging and a proper preoperative evaluation may help prevent unexpected outcomes on the contralateral lid. Preoperative evaluation should include testing for Hering's law, which remains useful in understanding the phenomenon of induced contralateral eyelid retraction in the context of ptosis. Approximately 10% to 20% of patients with unilateral ptosis have some degree of induced retraction on clinical evaluation in the contralateral lid. When there is a positive Hering's test on preoperative examination, the surgeon should consider a bilateral ptosis procedure. The surgical approach to unilateral ptosis depends on the severity of the ptosis and its etiology, and the surgeon should be aware of which procedure is most likely to provide the best outcome in selected instances.
