Abstract
PURPOSE Surgical correction of myogenic ptosis is a sophisticated endeavor, as the disease is progressive and the post-operative course is prone to significant complications. We sought to review the literature for repair techniques in different types of myogenic ptosis. METHODS A PubMed/MEDLINE literature search of publications pertaining to surgical outcomes of progressive myogenic ptosis repair was performed. Studies included were original retrospective studies with a minimum of four patients. RESULTS A total of 27 articles were identified and divided by etiology of myogenic ptosis; either chronic progressive external ophthalmoplegia (CPEO), oculopharyngeal muscular dystrophy (OPMD), myasthenia gravis (MG), or mixed. Surgical techniques predominantly involved levator advancement, levator resection, frontalis sling, blepharoplasty, and Fasanella-Servat. Success rates ranged from 60.5% to 100%. Significant postoperative complications included ptosis recurrence, under-correction, over-correction, keratopathy, lagophthalmos, sling exposure, and sling infection. CONCLUSION Like surgical repair for other forms of ptosis, correction of progressive myogenic ptosis is guided by levator excursion. However, myogenic ptosis is especially challenging as it is characterized by worsening ptosis and the loss of protective corneal mechanisms. The goals of care with myogenic ptosis involves repairing ptosis just sufficiently to alleviate visual obstruction while avoiding adverse post-operative complications. This intentional under-correction subsequently increases susceptibility for ptosis recurrence. Myogenic ptosis repair therefore requires delicate balancing between function, sustained repair, and corneal protection.

Abstract
Drooping of the upper eyelid margin, aka blepharoptosis or "ptosis", is common. Whether the ptosis is severe or mild, congenital or acquired, aponeurotic or neuropathic or myopathic, proper management always begins with a detailed history and evaluation of the patient. The information gathered will direct the surgeon in choosing the technique most likely to give the best result. This article will briefly review common causes of ptosis, the evaluation of the ptosis patient as well as the two most common types of surgical intervention.

Abstract
Ptosis is defined as a drooping of the upper eyelid. It often results in functional and/or aesthetic impairment. Although often benign, ptosis may be the first symptom of a life-threatening condition (carotid dissection, intracranial aneurism, generalized myasthenia). Only a rigorous, systematic and clinical examination will allow the physician to distinguish "benign ptosis" from "urgent ptosis". The history should attempt to detect a daily variation in the ptosis, suggesting myasthenia gravis. Pupillary examination should rule out myosis, which would suggest Claude Bernard-Horner's syndrome (secondary to an internal carotid dissection until proven otherwise), or mydriasis, suggesting an intracranial aneurism. Once an emergency has been ruled out, the clinical examination should assess the levator muscle strength (helpful for determining the underlying etiology) and the Bell's phenomenon (the lack of which is predictive of postoperative corneal exposure). The amount of ptosis is not related to its etiology. At the conclusion of the examination, the physician must be able to classify the ptosis as either pseudoptosis, aponeurotic ptosis, neurogenic ptosis, myogenic ptosis, or junctional ptosis (myasthenia). Except for "urgent ptosis", requiring multidisciplinary medical treatment, surgery is the mainstay of treatment. The surgical technique is based on the etiology of the ptosis, the strength of the levator muscle and the phenylephrine test.

Abstract
Congenital myasthenic syndrome (CMS) describes a group of rare inherited disorders caused by impaired neuromuscular transmission at the motor endplate. Common ophthalmic manifestations associated with CMS include ptosis and ophthalmoplegia. A 19-year-old female presented with variable day-to-day ptosis secondary to CMS that was refractory to medical therapy. Bilateral silicone frontalis slings were used to stabilise the upper lid height and reduce fluctuation in severity of ptosis. Blepharoptosis surgery has been performed in patients with chronic myasthenia gravis (MG), but rarely in the setting of CMS. Blepharoptosis surgery in CMS patients with variable ptosis is difficult due to the risk of upsetting the original lid position and developing post-operative exposure keratopathy. Our case demonstrates that the frontalis sling procedure may be considered as an option in the management of variable blepharoptosis secondary to CMS.

Abstract
OBJECTIVE The surgical treatment of myogenic ptosis accompanying extraocular muscle paralysis is an intractable problem in the field of oculoplastic surgery due to the severe complications such as exposure keratopathy. It is promising to find an appropriate procedure to treat this kind of patients, which is able to ensure the safety and efficacy. METHODS The authors retrospectively reviewed 12 eyes of 6 patients who underwent the under-corrected "double V-Loop" frontalis suspension sling procedure for myogenic ptosis accompanying extraocular muscle paralysis and access the safety and efficacy of this kind of surgery. All the patients underwent corneal fluorescein staining and confocal microscopy before and after the surgery to inspect the corneal condition. The density of central corneal epithelial cells and endothelial cells were observed. RESULTS After the surgery, the eyelids contour was natural, and the symmetry was achieved in these cases. The average palpebral fissures height changed from 2.75 ± 1.41 mm to 4.50 ± 0.35 mm (P = 0.0007) and margin reflex distance 1 changed from -1.25 ± 1.22 mm to +0.50 ± 0.35 mm (P = 0.0002). Out of 12 operated eyes, mild postoperative lagophthalmos was present in 4 cases but without exposure keratopathy during the follow-up, the confocal microscopy showed that there were no significant differences in central corneal superficial epithelial cells (P = 0.93) and endothelial cells (P = 0.90) before and after the surgery. CONCLUSION The under-corrected "double V-Loop" frontalis suspension sling is a proper surgery in myogenic ptosis accompanying extraocular muscle paralysis, which leads to a low occurrence of exposure keratopathy, maintains the integrity of the cornea, and remains the patients' vision function.

Abstract
PURPOSE To report the effect of frontalis linkage without intraoperative eyelid elevation for the management of myopathic ptosis. METHODS Retrospective analysis of 21 (42 eyelids) myopathic patients with bilateral ptosis who were operated between 1999 and 2017. All patients had orbicularis weakness and poor or absent Bell's phenomenon. Surgery consisted of using an autogenous fascia sling to link the tarsal plate to the frontalis muscle without any degree of intraoperative eyelid elevation. The main outcome measures were margin reflex distance, brow height and degree of brow excursion and degree of lagophthalmos, and exposure keratitis. RESULTS After surgery, there were significant changes (p <0.0001) in both margin reflex distance and brow position. Mean margin reflex distance increased to 1.4 mm ± 1.34 DP and with full frontalis contraction, it reached 3.0 mm ± 1.73 DP, while mean brow position decreased 1.6 mm ± 1.59 SD, p < 0.0001. Postoperative lagophthalmos was not detected in 31 (74%) eyes. In the remaining 11 eyes (26%), lagophthalmos ranged from 1.2 to 5.2 mm (mean = 1.7 mm ± 0.74 DP). Mild inferior superficial keratitis was detected in 14 eyes (33.3%) of 7 patients only 3 of which had lagophthalmos. One patient needed additional surgery to correct unilateral eyelid retraction. Overall, 81.81% of the patients were pleased with the procedure. CONCLUSIONS Myopathic ptosis can be alleviated with a minimal amount of lagophthalmos by just linking the tarsal plate to the frontalis muscle without lifting the eyelid margin intraoperatively.

Abstract
PURPOSE To compare revision rates for ptosis surgery between posterior-approach and anterior-approach ptosis repair techniques. METHODS This is the retrospective, consecutive cohort study. All patients undergoing ptosis surgery at a high-volume oculofacial plastic surgery practice over a 4-year period. A retrospective chart review was conducted of all patients undergoing posterior-approach and anterior-approach ptosis surgery for all etiologies of ptosis between 2011 and 2014. Etiology of ptosis, concurrent oculofacial surgeries, revision, and complications were analyzed. The main outcome measure is the ptosis revision rate. RESULTS A total of 1519 patients were included in this study. The mean age was 63 ± 15.4 years. A total of 1056 (70%) of patients were female, 1451 (95%) had involutional ptosis, and 1129 (74.3%) had concurrent upper blepharoplasty. Five hundred thirteen (33.8%) underwent posterior-approach ptosis repair, and 1006 (66.2%) underwent anterior-approach ptosis repair. The degree of ptosis was greater in the anterior-approach ptosis repair group. The overall revision rate for all patients was 8.7%. Of the posterior group, 6.8% required ptosis revision; of the anterior group, 9.5% required revision surgery. The main reason for ptosis revision surgery was undercorrection of one or both eyelids. Concurrent brow lifting was associated with a decreased, but not statistically significant, rate of revision surgery. Patients who underwent unilateral ptosis surgery had a 5.1% rate of Hering's phenomenon requiring ptosis repair in the contralateral eyelid. Multivariable logistic regression for predictive factors show that, when adjusted for gender and concurrent blepharoplasty, the revision rate in anterior-approach ptosis surgery is higher than posterior-approach ptosis surgery (odds ratio = 2.08; p = 0.002). CONCLUSIONS The overall revision rate in patients undergoing ptosis repair via posterior-approach or anterior-approach techniques is 8.7%. There is a statistically higher rate of revision with anterior-approach ptosis repair.

Abstract
Myasthenia gravis is a relatively common neuromuscular disorder, with ocular myasthenia gravis being a subset defined as myasthenia gravis limited to the orbicularis, levator, and extraocular muscles. Patients with ocular myasthenia gravis can have disabling diplopia or functional blindness from ptosis and in most cases treatment is required. Like generalized myasthenia gravis, there are a variety of treatments available that include pyridostigmine, immunosuppression, intravenous immunoglobulin, plasmapheresis, thymectomy, lid crutches, ptosis surgery, and extraocular muscle surgery. Unfortunately, there is limited data on the use of individual treatments in ocular myasthenia gravis and no data comparing treatments. Using a combination of available data on treatment of generalized myasthenia gravis, data on treatment of ocular myasthenia gravis, best practices, and clinical experience we will provide a rational framework for treatment of ocular myasthenia gravis.

Abstract
Background To present the outcomes of the tarsal switch procedure using an anterior approach to correct severe ptosis with poor levator muscle function (<4 mm) with absent or poor Bell’s phenomenon. Methods This retrospective case series included 11 patients with severe neurogenic or acquired myogenic palpebral ptosis. All patients underwent the tarsal switch procedure through an anterior approach from 2012 to 2015. Margin reflex distance (MRD1 and MRD2) and the palpebral fissure were evaluated preoperatively and postoperatively. Data were compared using the Wilcoxon signed-rank test. P-values <0.05 were considered to indicate statistical significance. Results Surgery was performed on 18 eyelids (11 patients). The median age at surgery was 57 years (range, 29-86 years). Four patients had unilateral ptosis and seven had bilateral ptosis. Nine patients had myogenic ptosis and two had neurogenic ptosis. Postoperatively, the chin-up position improved in all patients. The MRD1 increased statistically significantly, from 0 mm preoperatively to 1.0 mm postoperatively (P=0.001). The MRD2 decreased statistically significantly, from 4.5 mm preoperatively to 3.0 mm postoperatively (P=0.001). The palpebral fissure did not change (4.0 mm preoperatively to 4.0 mm postoperatively) (P=0.13). Conclusions The tarsal switch procedure through an anterior approach is an effective alternative for correcting severe ptosis, especially neurogenic or acquired myogenic ptosis. This procedure can be performed with minimal risk of ocular surface exposure and provides stable outcomes.

Abstract
INTRODUCTION Medical management can have limitations in improving ptosis in patients with myasthenia gravis (MG). We present our experience of ptosis surgery in MG. MATERIALS AND METHODS Clinical records of all patients with MG undergoing ptosis surgery from September 2007 to November 2013 in a single center were retrospectively reviewed. Change in upper marginal reflex distance (uMRD) was the main outcome measure. RESULTS Sixteen external levator advancement (ELA) procedures were performed on 11 MG patients. Fourteen of 16 procedures had pre- and postoperative uMRD documented. Thirteen of 14 procedures had improved lid height; mean increase in uMRD was 2.4 mm (P=0.0005651). Two patients required secondary lid elevation. Postoperative complications included more noticeable diplopia (n=1) and exposure keratopathy (n=1). CONCLUSION Ptosis surgery is a useful adjunct to medical therapy to improve lid height in MG patients with ptosis. Risks of diplopia and exposure keratopathy should be discussed with the patient pre-operatively.

Abstract
PURPOSE Treatment of blepharoptosis caused by ocular myasthenia gravis (OMG) is challenging in patients with serious side effects or failed response to medical therapy. Only a few surgical reports have been published for refractory myathenic blepharoptosis. This study is aimed at the evaluation of the surgical outcome of blepharoptosis correction in intractable OMG patients. METHODS Twelve OMG patients who accepted frontalis sling with frontalis orbicularis oculi muscle (FOOM) flap for blepharoptosis correction were reviewed. Patients' demographies, perioperative changes of the interpalpebral fissure height (IPFH), margin reflex distance 1 (MRD1), levator function (LF), and quality of life (QOL) score were evaluated. RESULTS The duration of OMG ranged from 3 to 31 years. LF was normal in 6 patients, good in 5, and poor in 1. There is no significant change of LF before and after surgery. MRD1 improved significantly from -1.8 mm (range, 0 to -5 mm) preoperatively to 2.9 mm (range, 2-4 mm) postoperatively. IPFH improved significantly from 3.8 mm (range, 2-6 mm) preoperatively to 7.8 mm (range, 6-9 mm) postoperatively. Upper eyelid margin was above the pupil in all patients. QOL score improved significantly from 18.2 (range, 14-23) preoperatively to 5.8 (range, 0-10) postoperatively. CONCLUSIONS Our report reveals that surgical correction of the blepharoptosis is effective for patients with intractable OMG and that frontalis suspension with FOOM flap is a valuable option because of its ready availability and pliability. All patients are satisfied with the results, especially the improvement of QOL.

Abstract
Ptosis repair was performed in patients with ocular myasthenia gravis by a posterior approach (Fasanella-Servat, 12 eyelids of nine patients) or levator advancement (eight eyelids of five patients) techniques. There were eight males and five females. Median age was 73 years and range 30-86 years. The median duration of myasthenia was 10 years and range 2 to 28 years. Pyridostigmine and prednisone were widely used prior to surgical referral, but ineffective or intolerable in all. The mean preoperative upper margin-reflex distance (MRD) was 0.55 mm (range -1 to 2 mm). The levator excursion range was 10 to 16 mm and mean 12.4 mm. Mean follow-up was 9.1 months. Postoperatively, the MRD ranged from 0.5 to 4 mm, with a mean of 2.3 mm. Two patients had lagophthalmos postoperatively (one posterior approach, one levator advancement) that did not require correction. Three of five patients who underwent levator advancement required repeat ptosis repair.
