How does the Surgical Repair of Ptosis Impact Refractive Error?

PURPOSE: To identify a correlation between the degree of congenital ptosis and levels of refractive error, visual stimulus deprivation and anisometropic amblyopia, and any improvement with surgical intervention. METHODS: A prospective investigation of 30 patients aged 3 months to 8 years, with a diagnosis of unilateral or bilateral congenital ptosis. A full orthoptic assessment and cycloplegic refraction were performed and patients requiring surgical intervention for ptosis were at surgeon discretion. RESULTS: The mean age at presentation was 27.1 months. The prevalence of amblyopia ranged from 19 to 29%. There was no significant difference in the levels of astigmatism throughout the follow-up period between patients who underwent surgical intervention and who did not. There was a significant improvement in the visual acuity of the affected eye (p = .03) and both eyes open (p = .02), in patients who did not undergo surgery. This was then repeated on patients who underwent surgical intervention which showed no significant difference in the affected eye or both eyes open; p = .27, p = .32, respectively. CONCLUSION: There is no significant change in the levels of astigmatism in both patients who underwent surgery and those who did not. Conservative management of congenital ptosis, while counterintuitive, proves not to deleteriously affect the visual potential of these patients.

Journey of frontalis muscle advancement in severe blepharoptosis: Review of the techniques, modifications, and outcomes.

We aimed to review the degree of standardization of frontalis muscle (FM)-orbicularis muscle advancement techniques in the management of severe congenital blepharoptosis and also study the evidence which supports the procedure correcting blepharoptosis. The undisputed rationale of all types of brow suspension in the management of severe blepharoptosis is based on the concept that slings are the conventional way to simultaneously suspend a ptotic eyelid and transmit the contractile action of the FM to the tarsal plate. Traditionally, frontalis suspension using sling has been used to treat patients with severe congenital blepharoptosis with poor levator function; however, postoperative lagophthalmos, forehead scarring, and recurrence remain major concerns. Since the early 80s, a significant number of consecutive articles have suggested that the eyelid can be effectively suspended by directly suturing FM to the tarsal plate. This review article intends to evaluate the level of standardization of FM advancement techniques in the management of severe blepharoptosis. 'In addition, to determine if the procedure should be performed in a standard manner, and is there enough evidence available to recommend FM advancement as a useful surgical technique.

"Blue Scrub Lid Retraction": Changes in Eyelid Position on the Day of Surgery.

PURPOSE: The aim of this study is to test the hypothesis that margin-reflex distance 1 (MRD1) on the day of surgery will be higher than the MRD1 measured at the in-clinic consult visit among patients undergoing blepharoptosis repair due to an increased sympathetic drive. METHODS: Patients evaluated for involutional blepharoptosis repair were prospectively enrolled over a 12-month period in this single-center, self-controlled study. Three investigators independently determined MRD1 using cropped photos taken of patients at the in-clinic consult visit and on the day of surgery. A difference in height was tested for by using the 2-tailed Wilcoxon signed rank test. RESULTS: Evaluated in this study were 76 eyelids from 38 patients. Over 3-quarters of study participants had a higher MRD1 in the right and OSs on the day of surgery than at their in-clinic consultation visit (p < 0.001). The mean increase in MRD1 for the right eyelid and left eyelid was 1.0 mm (range: 0-3.15 mm) and 1.1 mm (range: 0-2.7 mm), respectively. CONCLUSIONS: In patients with involutional blepharoptosis, we conclude that MRD1 is higher on the day of surgery as compared with the in-clinic consult visit. This may be secondary to the stress of surgery and an associated increase in sympathetic drive. In some cases, this change in eyelid position led to resolution of apparent involutional ptosis altogether. Caution should be used when considering deferral of ptosis repair on the basis of exam findings present on the day of surgery.

Eyelid retraction during smiling in a patient with monocular congenital ptosis: a case report.

BACKGROUND: Blepharoptosis is a common symptom in ophthalmology clinic, but eyelid retraction when smiling in a ptosis eye is a rare manifestation. Here we report a novel manifestation that eyelid retraction during smiling in a patient with monocular congenital ptosis. CASE DESCRIPTION: A 10-year-old girl with isolated and mild unilateral congenital ptosis showed eyelid retraction in ptotsis eye when smiling together with a lid lag on downgaze. She didn't have any systematic and ocular diseases other than myopia and astigmatism.Eyelid retraction during smiling is 5 mm, resulting in a significant difference in the height of bilateral palpebral fissures.As for ptosis, is mild.The margin to reflex distance 1 is 1.0 mm on the right eye(ptosis eye) and 3.0 mm on the left eye. A lid lag of 1.0 mm on downward gaze was noted on the right, she could close her eyes fully while sleeping.The ice pack test, laboratory test for thyroid function, whole-exome sequencing (WES) and magnetic resonance imaging(MRI) of the orbital and ocular motor nerves showed normal results.Her symptoms alleviated after 6 months, with the retraction of the right upper eyelid when smiling was approximately 3 mm, thus the difference in the palpebral fissure height when smiling was smaller than that at the initial presentation. CONCLUSION: Blepharoptosis may accompanied with abnormal innervation like eyelid retraction, this phenomenon can be alleviated with age.The results of the levator muscle function test should be carefully examined to determine whether it is ptosis in an impaired innervation eyelid.

Accuracy of Repetitive Ocular Vestibular-Evoked Myogenic Potentials to Diagnose Myasthenia Gravis in Patients With Ptosis or Diplopia.

BACKGROUND AND OBJECTIVES: We developed repetitive ocular vestibular-evoked myogenic potentials (roVEMP) as an electrophysiologic test that allows us to elicit the characteristic decrement of extraocular muscles in patients with ocular myasthenia gravis (OMG). Case-control studies demonstrated that roVEMP reliably differentiates patients with OMG from healthy controls. We now aimed to evaluate the diagnostic accuracy of roVEMP for OMG diagnosis in patients with ptosis and/or diplopia. METHODS: In this blinded prospective diagnostic accuracy trial, we compared roVEMP in 89 consecutive patients presenting with ptosis and/or diplopia suspicious of OMG with a multimodal diagnostic approach, including clinical examination, antibodies, edrophonium testing, repetitive nerve stimulation of accessory and facial nerves, and single-fiber EMG (SFEMG). We calculated the roVEMP decrement as the ratio between the mean of the first 2 responses compared with the mean of the sixth-ninth responses in the train and used cutoff of >9% (unilateral decrement) in a 30 Hz stimulation paradigm. RESULTS: Following a complete diagnostic work-up, 39 patients (44%) were diagnosed with ocular MG, while 50 patients (56%) had various other neuro-ophthalmologic conditions, but not MG (non-MG). roVEMP yielded 88.2% sensitivity, 30.2% specificity, 50% positive predictive value (PPV), and 76.5% negative predictive value (NPV). For comparison, SFEMG resulted in 75% sensitivity, 56% specificity, 55.1% PPV, and 75.7% NPV. All other diagnostic tests (except for the ice pack test) also yielded significantly higher positive results in patients with MG compared with non-MG. DISCUSSION: The study revealed a high sensitivity of 88.2% for roVEMP in OMG, but specificity and PPV were too low to allow for the OMG diagnosis as a single test. Thus, differentiating ocular MG from other neuro-ophthalmologic conditions remains challenging, and the highest diagnostic accuracy is still obtained by a multimodal approach. In this study, roVEMP can complement the diagnostic armamentarium for the diagnosis of MG. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that in patients with diplopia and ptosis, roVEMP alone does not accurately distinguish MG from non-MG disorders.

Determining the Degree of Perceptible Static Eyelid Asymmetry and Effect of Face Inversion: A Cross-sectional Pilot Study.

PURPOSE: To determine the degree of static eyelid asymmetry required to be perceptible and whether this is affected by image inversion. METHODS: Images of 3 volunteers were digitally manipulated to have eyelid asymmetry of 0.5 mm, 1 mm, or 1.5 mm of 3 different types, upper lid ptosis, upper lid retraction, and lower lid retraction. Forty-nine laypersons stated whether the images were symmetrical or asymmetrical. A separate inversion survey, completed by 29 clinicians, consisted of symmetrical images and 1 mm asymmetrical images, with half being inverted. RESULTS: Upper lid ptosis, upper lid retraction, and lower lid retraction were not detected by most laypeople at 0.5 mm of severity (18.9%, 6.7%, 18.9% detection, respectively) but all 3 were detected by the majority of participants once asymmetry reached 1 mm severity (65.7%, 61.8%, 51.0% detection, respectively) and rose to over 70% identification at 1.5 mm (92.2%, 73.5%, 73.5% detection, respectively). Inversion of the images led to 19.7% lower rates of correct identification of asymmetrical faces compared with images presented in the correct orientation (80.7% asymmetry identified in normal images, 61.0% inverted, p < 0.001). CONCLUSIONS: All asymmetries were detectable by a majority of laypersons at a severity of 1 mm. Image inversion decreases a clinician's ability to detect a 1 mm asymmetry, indicating an impaired asymmetry perception in the intraoperative view. This study provides research to counsel patients with varying degrees of eyelid asymmetry.

Spontaneous Blinking Kinematics After Frontalis Muscle Flap Advancement.

PURPOSE: To measure the spontaneous blinking metrics after blepharoptosis correction with frontalis muscle flap advancement. METHODS: A video system was employed to measure the amplitude and velocity of spontaneous blinking of 24 eyelids after the frontalis muscle flap surgery for blepharoptosis correction. A control group with no eyelid disorders was also measured. The data of 13 eyelids who had frontalis slings with autogenous fascia, which were previously collected with the same method in another study, were used for comparison. Digital images were used to measure the superior margin reflex distance and the presence of lagophthalmos during a gentle closure of the palpebral fissure. Superficial keratitis was assessed by corneal biomicroscopy. RESULTS: The mean amplitude of spontaneous blinking was 6.3 mm in controls, 2.6 mm in the frontalis flap patients, and 2.1 mm in the fascia sling group. The mean blink velocity was 133.8 mm/second in controls, 39.0 mm/second (3.7 standard error) after the frontalis flap, and 36.3 mm/second in patients with frontalis sling with fascia. For these 2 parameters, there was no statistical difference between the surgical groups, but a significant reduction when compared with the control group. No significant association was found between lagophthalmos and keratitis and the surgical procedure. CONCLUSIONS: There is no difference between the blinking metrics of eyelids operated using the frontalis muscle flap advancement technique or frontalis sling with autogenous fascia. The presence of lagophthalmos and keratitis also does not differ between the 2 procedures.

An unusual ophthalmologic finding in a patient with congenital central hypoventilation syndrome.

INTRODUCTION: Congenital Central Hypoventilation Syndrome (CCHS) is a rare disease due to a severely impaired central control of breathing and dysfunction of the autonomic nervous system. Ophthalmologic abnormalities are common in patients with CCHS and include horizontal strabismus, pupil and iris abnormalities and ptosis. We report a unique case of CCHS in association with monocular elevation deficit (MED) in a boy diagnosed with CCHS at birth. CASE DESCRIPTION: We report a case of a boy with a confirmed diagnosis of CCHS (complete sequencing of the paired-like homeobox 2b (PHOX2B) gene) after presenting little respiratory effort and cyanosis at birth. The ophthalmological examination shows an impaired elevation of the left eye, both in adduction and abduction, associated with mild and variable left ptosis. His mother has observed that the left eyelid elevates when the child feeds. A deviation in the primary gaze position or a chin-up position are not present. The funduscopic examination is normal. Given that deviation is limited to upgaze, the ptosis is mild and the patient's age, observation is decided. CONCLUSIONS: Ophthalmologic abnormalities are common in patients with CCHS and include horizontal strabismus, pupil and iris abnormalities and ptosis. To the best of our knowledge, this is the first report of MED in association with CCHS. Further studies are needed to determine if an association between MED and CCHS exists or is just a casual finding in this case.

Modified Conjoint Fascial Sheath and Levator Muscle Complex Suspension for the Correction of Simple Severe Congenital Ptosis in Pediatrics and the Effect on Refractive Status.

PURPOSE: To evaluate the outcomes of modified combined fascia sheath and levator muscle complex suspension to correct severe congenital ptosis in pediatrics and the effect on refractive status. METHODS: This prospective, case series study enrolled patients (aged ≤18 years) with simple severe congenital ptosis at Zhongshan Ophthalmic Center. All patients were treated with combined fascia sheath + levator muscle suspension and followed up for 3 months. Preoperative and postoperative cycloplegic refraction and the best-corrected visual acuity were performed. The types of astigmatism include with-the-rule, against-the-rule, and oblique. RESULTS: Thirty-six patients (50 eyes) were enrolled. The mean age was 7.11 ± 3.72 years. The surgery success rate was 90.0%. Following surgery, the eyelid contour of all eyes exhibited natural symmetry and satisfactory curvature. The eyelid height difference in OUs was ≤1 mm for 42 eyes. For 47 eyes, the eyelid crease was symmetry. Two eyes had conjunctival prolapse, and 1 eye developed trichiasis. After surgery, cylinder power changed from mean -1.14 ± 1.27 D to -1.54 ± 1.25 D ( p < 0.001) and best-corrected visual acuity improved from mean 0.205 ± 0.217 logarithm of the minimum angle of resolution to 0.168 ± 0.176 logarithm of the minimum angle of resolution ( p = 0.048). The quantities of with-the-rule increased from 35 eyes to 41 eyes, oblique from 4 eyes to 6 eyes, while against-the-rule decreased from 11 eyes to 3 eyes ( p = 0.01). CONCLUSIONS: Combined fascia sheath + levator muscle suspension under general anesthesia is effective and safe for severe congenital ptosis in pediatrics. However, astigmatism increased and the types of astigmatism changed after surgery.

Lower eyelid position before and after blepharoptosis repair.

PURPOSE: This study aimed to examine the changes in lower eyelid position after blepharoptosis surgery and the factors that influence the outcome. METHODS: We conducted a retrospective study of 155 eyes of 89 patients who underwent blepharoptosis surgery between June 2019 and October 2022. The margin reflex distance (MRD)-1 and MRD-2 were examined preoperatively and 3 months postoperatively in two groups: one with lower scleral show (LSS) (n = 37) and one without LSS (n = 118). The clinical characteristics of the two groups were compared. RESULTS: Both the LSS and non-LSS groups showed significant postoperative improvement in MRD-1 scores (p < .01, p < .01, respectively). MRD-2 was significantly reduced in the LSS group, while it remained unchanged in the non-LSS group (p < .01, p = .27, respectively). There were no significant differences between the two groups in age, sex, history of hard contact lens use, preoperative levator function, use of topical steroids, history of endophthalmic surgery, or history of filtration surgery; however, the LSS group significantly used prostaglandin analogs (PGAs) (p = .03). Postoperatively, MRD-2 decreased in 13 eyes (35.1%) and was maintained in 24 eyes (64.9%) in the LSS group and was maintained in all eyes in the non-LSS group. In the LSS group, we also examined the association between postoperative MRD-2 reduction and the use of PGAs and found that more patients with MRD-2 reduction used PGAs (p = .02). CONCLUSION: Lower scleral show in PGAs-associated blepharoptosis is expected to improve after blepharoptosis surgery.

Treatment of Severe Ptosis by Conjoint Fascial Sheath Suspension.

OBJECTIVE: To explore the role of conjoint fascial sheath (CFS) suspension in the treatment of severe ptosis. METHODS: A total of 110 patients with severe ptosis who were admitted to our hospital from May 2018 to December 2020 were included. Fifty-seven patients treated with frontalis suspension were assigned into group A, and the remaining 53 patients treated with CFS suspension were assigned into group B. The curative effect, ocular surface alterations, complications, and satisfaction in the two groups were compared. RESULTS: Patients in group B suffered from severe upper eyelid retraction and lid lag than those in group A, as well as more limited range of motion (ROM) (P < 0.05). The curative effect and patient satisfaction in group B were higher than those in group A (P < 0.05). Postsurgical complications in group B were fewer than those in group A (P < 0.05). CONCLUSION: CFS suspension is effective in the treatment of severe ptosis.

Cluster headache in children and adolescents: a systematic review of case reports.

AIM: To describe the clinical characteristics and therapeutic options available to paediatric patients with cluster headache. METHOD: Based on a literature search of the medical databases PubMed, LILACS, and Web of Science and using selected descriptors, we carried out a systematic review of case reports on cluster headache in paediatric patients published from 1990 to 2020. RESULTS: Fifty-one patients (29 males, 22 females) with a mean (SD) age of 9 years 7 months (3y 10mo; range 2-16y) were diagnosed with cluster headache. The mean (SD) diagnosis was made 27.8 months (26.2mo) after the onset of cluster headache. Pain occurred at night or on waking up (76.5%) and consisted of 1 to 3 attacks per day (62.7%) lasting 30 to 120 minutes (68.6%). Headaches were unilateral (90.2%), had a pulsatile character (64.7%), and severe intensity (100%). There were autonomic manifestations (90.2%) predominantly ipsilateral to pain, in this order: lacrimation; conjunctival injection; nasal congestion; ptosis; eyelid oedema; and rhinorrhoea. Sumatriptan and oxygen inhalation were the most effective treatments for acute manifestation. Prophylaxis, corticosteroids, verapamil, and gabapentin were the most effective drugs. INTERPRETATION: Due to the small number of published studies, this review could not provide reliable data; however, it appears that cluster headache in children and adolescents is similar to adults, both in clinical characteristics and treatment. What this paper adds Cluster headache in children and adolescents is poorly studied. Cluster headache is uncommon before 10 years of age and diagnosis is difficult in the first few years of life. Treatment of cluster headache in children and adolescents is similar to that used in adults. The notion of the effectiveness of prophylactic treatment is based only on authors' experience.

Assessment of Long-Term Anterior and Posterior Topographic Changes in the Cornea After Ptosis Surgery Using Fourier Harmonic Analysis.

PURPOSE: We aimed to assess the corneal refractive changes induced by ptosis surgery in patients with acquired ptosis using Fourier harmonic analysis. METHODS: This retrospective observational study enrolled consecutive patients who underwent levator aponeurotic surgery for acquired ptosis at the Department of Ophthalmology in the University of Tokyo Hospital from May 2016 to January 2018. Best corrected visual acuity, central corneal thickness, average keratometric corneal power (AvgK), corneal astigmatism, and topographic data using Fourier analysis were analyzed preoperatively and 6 months postoperatively. RESULTS: Thirty-two eyes of 32 patients (age, 72.6 ± 8.5 years) were included in this study. There were no significant differences in best corrected visual acuity and central corneal thickness. However, there were significant decreases in anterior AvgK, anterior corneal astigmatism, and posterior corneal astigmatism 6 months postoperatively (all, P < 0.001). Fourier harmonic analysis showed that the anterior spherical component significantly decreased 6 months postoperatively (P < 0.001). There were no significant differences in other components of the anterior and posterior cornea. There was a significant negative correlation between preoperative posterior AvgK and changes in posterior AvgK (r = -0.891, P < 0.001) and between preoperative posterior corneal astigmatism and changes in posterior corneal astigmatism at 6 months (r = -0.858, P < 0.001). CONCLUSIONS: Anterior and posterior corneal keratometry and posterior corneal astigmatism significantly changed 6 months after ptosis surgery for acquired ptosis.

Oliver McFarlane syndrome: two new cases and a review of the literature.

BACKGROUND: Oliver McFarlane syndrome is a rare syndrome. Clinical presentations include trichomegaly, chorioretinal degeneration, pituitary hormone deficits, and neurological manifestations. Genetic analysis has recently placed this syndrome within the group of PNPLA6-related disorders. Here, we describe two new individuals and review the previously published cases. MATERIALS AND METHODS: Clinical investigations were carried out in accordance with local guidelines and clinical information was retrieved from medical records. Genetic studies were carried out using next-generation sequencing based clinical exome sequencing. A PubMed literature search was performed with a review of the published clinical cases of Oliver McFarlane syndrome. RESULTS: Our first individual was a 36-year-old woman with 32 years of follow up and our second individual was a 3-year-old boy. Both individuals were born preterm and presented with prolonged neonatal respiratory distress, trichomegaly, early growth retardation, retinopathy and sparse depigmented hair. So far, none of our cases have demonstrated cognitive impairment or progressive neurological symptoms, but the child revealed persistent abnormal lung structure. Both individuals were compound heterozygous for pathogenic PNPLA6 variants, one of which was novel. We found other 31 clinically documented published cases. CONCLUSIONS: Our two new unrelated cases of Oliver McFarlane Syndrome demonstrate early ophthalmological and systemic findings of this rare syndrome and the progressive nature of the retinopathy with a long follow-up. PNPLA6-related disorders are a phenotypically highly heterogenous group where alterations in the phosphatidylcholine metabolism can lead to manifestations in different tissues with no clear genotype-phenotype correlation.

Visual loss from dermal fillers.

BACKGROUND: An increasing number of people are undergoing non-surgical aesthetic procedures, especially injections of botulinum toxin and dermal fillers. While toxin injections have lower rates of complications, profound and serious consequences can arise with the use of dermal fillers. CASE: A 29-year-old woman presented to the eye casualty department with sudden visual loss, ptosis and ophthalmoplegia after having had non-surgical rhinoplasty in a beauty salon in West London. The filler was administered by a healthcare professional not registered with the General Medical Council (GMC) or similar governing body. DISCUSSION: Despite prompt measures on arrival at our service, the symptoms of visual loss, ptosis and ophthalmoplegia persisted. Attempts from the patient and medical services to report the incident (to trading standards and the police) were to no avail. CONCLUSION: This case highlights the poor treatment response to filler-related ophthalmic complications. It is also evident that in the United Kingdom, there appears to be poor regulation in the use of these products, a lack of clear guidelines for the management of their complications and finally no recourse for patients to challenge practitioners who lack medical registration and are not held accountable.

Autoantibodies in Japanese patients with ocular myasthenia gravis.

INTRODUCTION: The majority of patients with myasthenia gravis (MG) initially present with ocular symptoms, but it is difficult to predict which cases will remain as ocular MG (OMG) or will progress to generalized MG. Herein we evaluated the serologic profile of Japanese OMG and its relationship with clinical features. METHODS: Seventy-three patients with OMG from five Japanese myasthenia gravis (MG) centers were enrolled. Live cell-based assays (CBAs) were used to determine the presence of autoantibodies (Abs) to clustered adult (2α, ß, δ, ε) and fetal (2α, ß, δ, γ) acetylcholine receptor (AChR) isoforms, muscle-specific receptor tyrosine kinase (MuSK), and lipoprotein receptor-related protein-4 (LRP4). RESULTS: Thirty-four of 73 (46.5%) serum samples were positive for Abs against both the adult-type and fetal-type AChR, as expected, but 7 (9.6%) and 2 (2.7%) were positive only for fetal or adult AChR-Abs, respectively. Four (5.4%) samples were positive for MuSK-Abs, but two of these also contained antibodies to fetal AChR or LRP4. Twenty-six (35.6%) samples were seronegative. DISCUSSION: Abs against fetal-specific AChR, MuSK, and LRP4 are found in some patients with OMG. Future studies attempting to predict conversion from ocular symptoms to generalized MG may benefit from measurement of these antibodies.
