Temporary unilateral upper eyelid retraction: an unreported rare complication of rhinoplasty.

BACKGROUND: Upper eyelid retraction may develop due to various neurogenic, myogenic, and mechanistic causes. Although the development of lagophthalmus after rhinoplasty has been described in the literature, upper eyelid retraction after uncomplicated rhinoplasty has not been reported before. CASE PRESENTATION: This report presents a case of unilateral upper eyelid retraction observed six days after uncomplicated rhinoplasty. A 40-year-old female patient presented with left upper eyelid retraction on the sixth day of uncomplicated closed-approach structural rhinoplasty. The patient was able to close her eyelids completely and eye movements were normal in all directions of gaze. Anterior and posterior segment examinations were in normal range. We prescribed artificial tear drop and night-time liquid tear gel. After four weeks of conservative treatment, the upper eyelid retraction was improved without any complication. No recurrence was observed at 6-month follow-up. CONCLUSION: This is the first case presenting with upper eyelid retraction without lagophthalmus after uncomplicated rhinoplasty. Ophthalmologists should be aware that such a complication may occur quite rarely and may regress without sequelae with conservative treatment.

Tarsal Buckling and Entropion after Levator Aponeurosis Advancement in Patients with Floppy Eyelid Syndrome.

Two patients with floppy eyelid syndrome presented with severe eye pain and foreign body sensation after recent levator aponeurosis advancement. The examination in both patients was notable for entropion of the upper eyelid, and upper lid eversion revealed deformity of the tarsus in both patients. Surgical revision with full-thickness horizontal tarsotomy and limited excision of the abnormal tarsus corrected the deformity. The authors propose a mechanism for this phenomenon and a modification of surgical technique that may prevent this complication.

Congenital Eyelid Imbrication and Floppy Eyelid Syndromes Complicated by Eversion due to Prostaglandin E Infusion in a Patient With Trisomy 21 and Tetralogy of Fallot.

Congenital eyelid imbrication syndrome is a rare eyelid finding where a long upper lid overlaps the lower lid when the eyes are closed. To date, congenital eyelid imbrication syndrome has been described in the literature less than 10 times. We present a case of congenital eyelid imbrication syndrome in a patient with trisomy 21 and tetralogy of Fallot on a prostaglandin E infusion to maintain a patent ductus arteriosus prior to definitive heart surgery. While on the infusion, the patient developed peripheral edema and flushing due to vasodilation. This coincided with eyelid swelling, conjunctival chemosis, and eversion of the eyelids. Upon cessation of the prostaglandin E1 infusion, his eyelid eversion resolved.

Effects of Preoperative Intravenous Versus Subcutaneous Tranexamic Acid on Postoperative Periorbital Ecchymosis and Edema Following Upper Eyelid Blepharoplasty: A Prospective, Randomized, Double-Blinded, Placebo-Controlled, Comparative Study.

PURPOSE: To compare the effects of preoperative tranexamic acid (TXA) administered intravenously (IV) versus subcutaneously on postoperative ecchymosis and edema in patients undergoing bilateral upper eyelid blepharoplasty. METHODS: A prospective, double-blinded, placebo-controlled study of patients undergoing bilateral upper eyelid blepharoplasty at a single-center. Eligible participants were randomized to preoperatively receive either (1) 1 g of TXA in 100 ml normal saline IV, (2) 50 µl/ml of TXA in local anesthesia, or (3) no TXA. Primary outcomes included ecchymosis and edema at postoperative day 1 (POD1) and 7 (POD7). Secondary outcomes included operative time, pain, time until resuming activities of daily living, patient satisfaction, and adverse events. RESULTS: By comparison (IV TXA vs. local subcutaneous TXA vs. no TXA), ecchymosis scores were significantly lower on POD1 (1.31 vs. 1.56 vs. 2.09, p = 0.02) and on POD7 (0.51 vs. 0.66 vs. 0.98, p = 0.04) among those that received TXA. By comparison (IV TXA vs. local subcutaneous TXA vs. no TXA), significant reductions in edema scores occurred in those that received TXA on POD1 (1.59 vs. 1.43 vs. 1.91, p = 0.005) and on POD7 (0.85 vs. 0.60 vs. 0.99, p = 0.04). By comparison (IV TXA vs. local subcutaneous TXA vs. no TXA) patients treated with intravenous and local subcutaneous TXA preoperatively were more likely to experience shorter operative times (10.8 vs. 11.8 vs. 12.9 minutes, p = 0.01), reduced time to resuming activities of daily livings (1.6 vs. 1.6 vs. 2.3 days, p < 0.0001), and higher satisfaction scores at POD1 (8.8 vs. 8.7 vs. 7.9, p = 0.0002). No adverse events occurred were reported. CONCLUSION: In an analysis of 106 patients, preoperative TXA administered either IV or subcutaneously safely reduced postoperative ecchymosis and edema in patients undergoing upper eyelid blepharoplasty. While statistical superiority between intravenous versus local subcutaneous TXA treatment was not definitively identified, our results suggest clinical superiority with IV dosing.

Outcome Comparison of Transconjunctival Müller's Muscle Recession With Levator Disinsertion (TMRLD) to Gold Weight Implantation in the Treatment of Paralytic Lagophthalmos.

PURPOSE: To compare clinical outcomes of transconjunctival Müller's muscle recession with levator disinsertion (TMRLD) to the traditional gold weight implantation in patients with paralytic lagophthalmos. METHODS: A retrospective nonrandomized comparative review of patients who had gold weight implantation and TMRLD surgeries for paralytic lagophthalmos from January 2016 to January 2023 was performed. The main outcome comparisons were measurement changes in lagophthalmos, marginal reflex distance 1, visual acuity, and corneal examination. Complication and reoperation rates were also compared. RESULTS: Twenty-six cases of gold weight implantation and 20 cases of TMRLD surgeries were identified. The changes in logMAR visual acuity between gold weight implantation and TMRLD groups were not statistically significant (-0.10 ± 0.48 vs. +0.05 ± 0.14, p > 0.05). The percent improvement in lagophthalmos (62.2% ± 51.8% vs. 58.4% ± 21.1%) and final marginal reflex distance 1 (2.22 ± 1.42 vs. 2.25 ± 1.41 mm) were also comparable between groups ( p > 0.05). Both groups showed similar changes in marginal reflex distance 1 (1.75 ± 1.31 vs. 2.83 ± 1.37 mm) and lagophthalmos (3.77 ± 3.92 vs. 3.36 ± 1.36 mm) ( p > 0.05). The overall complication (15.4% vs. 15.0%) and reoperation rates (15.4% vs. 15.0%) were comparable over the follow-up duration (291.6 ± 437.3 vs. 121.0 ± 177.8 days) ( p > 0.05). CONCLUSION: TMRLD is as safe and effective as the gold weight implantation in addressing paralytic lagophthalmos in patients with facial nerve palsy.

Canalicular Cyst After Punctal Plug Insertion.

This study describes the case of a patient with a canalicular cyst after punctal plug insertion. A 73-year-old male patient presented with a cystic mass on the right lower eyelid. He had undergone bilateral punctal occlusion with an absorbable punctal plug for dry eye syndrome 8 years ago. The lesion was palpable on the medial side of the right lower eyelid, accompanied by ectropion but without any inflammatory signs. Incision and drainage were performed, and a reduction in the size of the cystic mass was observed. Dacryocystography revealed cystic dilation of the right lower canaliculus, and a lacrimal probing test revealed right lower canalicular obstruction, leading to the diagnosis of a canalicular cyst. If a patient who has undergone punctal occlusion with punctal plugs presents with a mass in the medial canthus, a canalicular cyst should be considered in the differential diagnosis.

Granulomatosis with Polyangiitis Discovered Because of Repeated Upper Eyelid Swelling.

Background and objectives: The initial symptom that triggers granulomatosis with polyangiitis (GPA) diagnosis is rarely ocular. We describe a case with a single ocular lesion identified as probable GPA due to proteinase 3 (PR3)-antineutrophil cytoplasmic antibody (ANCA)-positivity according to the diagnostic criteria of the Ministry of Health in Japan; the lesion repeatedly worsened. Materials and methods: A 25-year-old female visited the Department of Ophthalmology, Asahi General Hospital, with upper eyelid swelling and conjunctival and episcleral hyperemia of the left eye. Both hordeolum and eyelid cellulitis were suspected, as the condition was resistant to treatment with antibiotic eye drops. Episcleritis was suspected due to localized hyperemia in the upper part of the eye. Upon treatment with antibacterial agents and steroid eye drops, the swelling and the hyperemia repeatedly worsened every week. Results: Blood samples were positive for PR3-ANCA, and GPA with an isolated ocular lesion was considered. After oral steroid treatment, the patient had no recurrence for 4 years. There was no systemic involvement in the upper respiratory tract, lungs, or kidneys. Conclusions: Diagnosing GPA with ocular symptoms as initial manifestations is challenging. GPA should be considered in treatment-resistant eyelid, orbital, and episcleral lesions, even at a young age.

[A case of eyelid fistula after cosmetic lateral canthoplasty].

A 35-year-old female presented with a chief complaint of exudates from the outer corner of the left eye for more than half a year after cosmetic lateral canthoplasty. A fistula was seen in the skin of the left eye 5 mm from the lateral canthus, with clear fluid inside it. Left eyelid fistula was diagnosed and surgically removed. The histopathological examination confirmed that the tissue connected with the fistula was lacrimal gland tissue. No recurrence was found during the 2-month follow-up.

Severe corneal involvement secondary to congenital lower eyelid epiblepharon.

PURPOSE: The study aims to examine an incidence and risk factors of severe corneal involvement in patients with congenital lower eyelid epiblepharon. METHODS: This retrospective, observational study included 509 patients (933 eyes) with congenital lower eyelid epiblepharon. Data on age, sex, affected side, past history, past surgery, presence or absence of concomitant periocular/ocular diseases, body height and weight, astigmatic power, and corneal involvement were collected. Severe corneal involvement included corneal scarring, vascularization, and perforation. RESULTS: Severe corneal involvement was found in 30 patients (5.9%) (34 eyes, 3.6%). Corneal scarring and perforation with scarring were shown in 29 patients (33 eyes) and 1 patient (1 eye), respectively. Nine patients (12 eyes) demonstrated concomitant corneal vascularization with corneal scarring. Logistic regression analysis showed that body mass index had an odds ratio of 1.057 (P = 0.078). Age and sex did not affect occurrence of severe corneal involvement (P > 0.050). CONCLUSIONS: In this study, 5.9% of patients showed severe corneal involvement in congenital lower eyelid epiblepharon. Logistic regression analysis indicates that a high body mass index was a possible risk factor of severe corneal involvement caused by congenital lower eyelid epiblepharon.

Sutureless transconjunctival insertion of eyelid gold weight.

OBJECTIVE: Surgical intervention for paralytic lagophthalmos has been gold weight implant through supratarsal crease incision for decades. The aim of this study is to propose a modified novel minimally invasive approach that can be described as sutureless and transconjunctival placement of eyelid weights. METHOD: Unilateral eyelid gold weights were implanted in six patients due to paralytic lagophthalmos secondary to peripheral facial nerve palsy. The patients were followed for an average of 6 months. RESULTS: Functional and aesthetically desired results were obtained in all six patients with suture-free transconjunctival placement of the eyelid weight. The patients did not experience any discomfort and avoided the burden of suture removal after the surgery. No complications developed in six patients during the postoperative period. CONCLUSION: Sutureless transconjunctival insertion of eyelid weight without external incision and suturing is practical, relatively easy and fast to perform. It preserves attachment of the levator muscle to the tarsus and presents functional results similar to conventional method. Fixing the implant with sutures to the tarsal plate is not needed. Sutureless of this method avoids external wound care, burden of suture removal for both surgeons and patients, and hence, suture related complications are eliminated.

Sutureless Amniotic Membrane Transplantation Using Pediatric Nasogastric Tube for Patients With Acute Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis.

PURPOSE: Evaluation of the results of sutureless amniotic membrane transplantation (AMT) using a pediatric nasogastric tube (NGT) for patients with acute Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) was aimed. METHODS: Twenty-six eyes of 13 patients with SJS/TEN with ocular involvement at a single tertiary care hospital between May 2020 and January 2022 were included in the study. An amniotic membrane was implanted to the ocular surface and conjunctival fornix using a modified symblepharon ring (MR) created by inserting NGT end-to-end. Patients were followed for at least 6 months. The mean duration of the surgery was recorded. The presence of corneal epithelial defect and vascularization, meibomian gland dysfunction (MGD) grade, conjunctival scarring, eyelid margin keratinization, symblepharon, and trichiasis were recorded. RESULTS: The mean age of the patients was 38.4±17.6 years. Amniotic membrane transplantation was performed only once for eight patients and twice for five patients. The mean duration of the surgery was 3.2±0.4 min. The modified symblepharon ring was removed 28 days after its application. At the first examination, 20 eyes (76.9%) had a corneal epithelial defect and 6 (23.1%) had early symblepharon. At the postoperative 6 months, although seven eyes (26.9%) had conjunctival scarring and 5 (19.2%) had eyelid margin keratinization, all patients were without any corneal defect, corneal vascularization, or symblepharon. Only 11 eyes (42.3%) showed MGD, and 1 eye (3.8%) showed trichiasis. CONCLUSIONS: This study showed that sutureless AMT using pediatric NGT could be a potentially fast and inexpensive treatment option for the treatment of SJS/TEN with ocular involvement at the bedside without the need for general anesthesia.

The Use of the Pericranial Periosteal Flap in Children for Treating Severe Lower Eyelid Retraction.

PURPOSE: To describe a surgical technique that can achieve significant lower eyelid elevation in severe retraction in children using a pericranial periosteal flap with skin graft. METHODS: A retrospective, single-center, case series of 3 consecutive pediatric cases are performed where a pericranial periosteal flap was used with a skin graft to manage severe lower eyelid retraction. Outcome measures include the extent of lower eyelid elevation (mm) and complications in the follow-up visits. RESULTS: Three children with severe lower eyelid retraction underwent the surgery. There were 2 boys and 1 girl with the mean age of 6.7 years (range, 5-8 years). The improvement of lower eyelid retraction was 3, 3, and 7 mm at 28, 24, and 6 months, respectively. No perioperative or postoperative complications occurred. CONCLUSIONS: Children with severe lower eyelid retraction often have a complex craniofacial and surgical history, and its surgical correction can be challenging. This case series present the successful use of pericranial flaps in treating severe lower eyelid retraction in children. The authors recommend this flap in children where traditional options have either failed or are not applicable.

Debunking the Puzzle of Eyelid Apraxia: The Muscle of Riolan Hypothesis.

PURPOSE: Apraxia of eyelid opening (AEO) has been defined by the presence of an intermittent nonparalytic bilateral loss of the volitional ability to open the eyes or to maintain the eyelids in a sustained elevated position. It is not known whether the condition represents an apraxia, a dystonia, or a freezing phenomenon, and several different nomenclatorial terms have been suggested for this condition including the so-called AEO (scAEO), blepahrocolysis, focal eyelid dystonia, and so on. The primary goal of this review is to attempt to clarify the pathogenetic mechanisms underlying scAEO as a clinical phenomenon. This review also addresses the issue of whether scAEO is part of the spectrum of blepharospasm (BSP) which includes BSP, dystonic blinks and other dystonic eyelid conditions, or whether it is a separate phenomenologically heterogeneous disease with clinical features that merely overlap with BSP. METHODS: A literature review was conducted in PubMed, MEDLINE, PubMed Central (PMC), NCBI Bookshelf, and Embase for several related keywords including the terms "apraxia of eyelid opening," "pretarsal blepharospasm," "blepharocolysis," "eyelid freezing," "eyelid akinesia," "levator inhibition," "blepharospasm-plus," as well as "blepharospasm." The clinical findings in patients with scAEO who fulfilled the classic diagnostic criteria of the disease that were originally set by Lepore and Duvoisin were included, while patients with isolated blepharospasm or dystonic blinks (DB) were excluded. In addition, electromyographic (EMG) studies in patients with scAEO were reviewed in detail with special emphasis on studies that performed synchronous EMG recordings both from the levator muscle (LPS) and the pretarsal orbicularis oculi muscle (OO). RESULTS: The apraxia designation is clearly a misnomer. Although scAEO behaves clinically as a hypotonic freezing phenomenon, it also shares several cardinal features with focal dystonias. The authors broadly categorized the EMG data into 3 different patterns. The first pattern (n = 26/94 [27.6%]) was predominantly associated with involuntary discharges in the OO muscle and has been termed pretarsal blepharospasm (ptBSP). The commonest pattern was pattern no. 2 (n = 53/94 [56.38%]), which was characterized by involuntary discharges in the OO muscle, together with a disturbed reciprocal innervation of the antagonist levator muscle and is dubbed disturbed reciprocal innervation (DRI). This EMG pattern is difficult to discern from the first pattern. Pattern no. 3 (n = 15/94 [15.9%]) is characterized by an isolated levator palpebrae inhibition (ILPI). This levator silence was observed alone without EMG evidence of contractions in the pretarsal orbicularis or a disturbed reciprocal relation of both muscles. CONCLUSION: EMG evidence shows that the great majority (84%) of patients show a dystonic pattern, whereas ILPI (16%) does not fit the dystonic spectrum. The authors propose that a spasmodic contraction of the muscle of Riolan may be the etiological basis for levator inhibition in patients with ILPI. If this is true, all the 3 EMG patterns observed in scAEO patients (ptBSP, DRI, and ILPI) would represent an atypical form of BSP. The authors suggest coining the terms Riolan muscle BSP ( rmBSP ) for ILPI, and the term atypical focal eyelid dystonia ( AFED ) instead of the term scAEO, as both terms holistically encompass both the clinical and EMG data and concur with the authors' theorem.

Is Corneal Subbasal Nerve Loss Associated With Meibomian Gland Loss in Inactive Mild and Moderate-to-Severe Graves' Ophthalmopathy?

PURPOSE: To evaluate meibomian gland and subbasal nerve plexus parameters in Graves' Ophthalmopathy (GO) and association of meibomian gland loss with corneal subbasal nerve plexus loss. METHODS: Fifty-two eyes of 52 mild and moderate-to-severe GO patients and 32 eyes of 32 healthy controls were enrolled. The meibomian gland dropout area (MGDA) and meibography scores were evaluated using noncontact meibography. In vivo confocal microscopy of corneal subbasal nerve plexus were conducted. ACCMetrics was used to obtain corneal parameters. RESULTS: Compared with healthy subjects, GO patients had worse upper and lower eyelid MGDA ( p < 0.001, for all) and upper, lower and total meibography scores ( p < 0.001, p = 0.001, and p < 0.001, respectively). Eyelid margin scores were worse in the GO group ( p < 0.001) and showed correlation with all noncontact meibography parameters ( p < 0.001 for all). All corneal subbasal nerve parameters were significantly lower in the GO group compared with the controls ( p < 0.05 for all). Subbasal nerve parameters of GO patients did not reveal a correlation with MGDA and meibography scores but showed correlations with ocular surface disease index score and Schirmer I test (r = -0.304; p = 0.042 and r = 0.336; p = 0.021, respectively). CONCLUSION: Meibomian gland and corneal nerve loss could be observed even in the inactive phase and mild GO. The lack of a correlation between meibomian gland loss and subbasal nerve loss suggests that meibomian gland loss is not a significant additional component in the pathogenesis of subbasal nerve damage in GO. Furthermore, our study revealed new evidence regarding the use of eyelid margin score to represent meibomian gland loss in GO.

Lower Eyelid Management in Facial Paralysis.

Correction of lower eyelid retraction is necessary to restore adequate blink in paralytic lagophthalmos. A plethora of static and dynamic surgical techniques have been described for lower eyelid repositioning. This article provides an approach to management of the paralytic lower eyelid, including a summary of existing techniques, case examples, and surgical technique for in-office lower eyelid suspension using a palmaris longus tendon graft.

Lower Eyelid Blepharoplasty: Minimizing Complications and Correction of Lower Eyelid Malposition.

Lid retraction is a feared complication of lower blepharoplasty. Anatomical variations like negative orbital vector, horizontal lid laxity, and preexisting lid retraction are more prone to lid malpositions. Meticulous and precise execution of a series of surgical steps is key to preventing complications. This includes minimizing surgical trauma, meticulous hemostasis, preserving innervation to the medial lid and pretarsal orbicularis, safe method of fat excision, septal tightening while maintaining lid traction, and conservative and titrated skin excision. Canthal fixation addresses lid laxity and maintains the lid stretched vertically while postoperative healing and fibrosis are taking place. Post-blepharoplasty lid retraction may occur due to failure to address lid laxity and the occurrence of middle lamellar fibrosis. Excessive skin excision may also result in anterior lamellar deficiency. The "sag and drag" concept is useful to evaluate the post-blepharoplasty retracted lid. The treatment of the retracted lid includes lid massage, replacing the anterior lamella, or releasing the middle lamellar fibrosis or a combination of techniques. In conclusion, understanding the mechanisms of lid retraction, careful preoperative assessment, and surgical precision will help surgeons to prevent and manage this complication.

Lower Eyelid Transcutaneous Blepharoplasty, Minimizing Complications and Correction of Lower Eyelid Malposition.

The periocular area is one of the first and most noticeable areas affected by ageing. Common signs of lower lid ageing include rhytids, prominent eye bags caused by prolapse of orbital fat pads, increased lid laxity leading to lid malpositioning, and deepening of tear troughs, all of which give a sunken aged appearance. Lower lid transcutaneous blepharoplasty can correct most of these problems providing excellent long-term aesthetic outcomes with minimal downtime for the patient. However, lower eyelid anatomy is complex, and a thorough understanding of its structure and function is needed to avoid serious complications such as lid malpositioning and blindness. In this review, we present the anatomy of the lower lid and useful surgical techniques to circumvent and avoid such complications.

Auricular Cartilage Graft for Lengthening Levator Muscle Aponeurosis With Ectropion Correction for Paralytic Lagophthalmos.

BACKGROUND: Paralytic lagophthalmos can have devastating consequences for vision if left untreated. Several surgical techniques have been described, including the utilization of alloplastic and autologous materials. OBJECTIVES: The authors sought to evaluate the effectiveness of the surgical treatment of paralytic lagophthalmos with combined techniques employing autologous material and involving the upper and lower eyelids. METHODS: Patients with paralytic lagophthalmos underwent stretching of the levator aponeurosis with interposition of conchal cartilage in the upper eyelid associated with sectioning of the orbitomalar ligament and lateral canthoplasty in the lower eyelid. The effectiveness of the technique was evaluated employing subjective (symptomatology) and objective parameters (ophthalmologic evaluation and measurements of lagophthalmos and marginal reflex distances 1 and 2). RESULTS: Eight patients with paralytic lagophthalmos were subjected to the proposed technique. In the postoperative period, 85.7% reported complete improvement of symptoms and 62.5% presented a normal eye examination. The mean lagophthalmos measurement was reduced by 5.93 mm, the mean marginal reflex distance 2 was reduced by 2.61 mm, and the mean marginal reflex distance 1 was reduced by 0.69 mm. CONCLUSIONS: The technique presented herein, employing autologous material associated with sectioning of the orbitomalar ligament and lateral canthoplasty, was effective in the treatment of paralytic lagophthalmos and did not present significant complications, such as extrusion.

Efficacy of allogenous fascia lata grafts in the management of lower eyelid retraction.

PURPOSE: To report on the use of allogenous fascia lata (FL) grafts in patients with lower eyelid retraction (LER). METHODS: In this retrospective study, a consecutive series of 27 patients (39 eyes) with LER who underwent lower eyelid elevation with FL was included. Examinations including measurement of the palpebral fissure vertical height (PFVH), the inferior scleral show distance, the margin reflex distance 2 (MRD 2), and the evaluation of conjunctival hyperemia were conducted at baseline and after a mean postoperative time of 25.9 ± 25.5 (5.0-81.0, median 13.0, last follow-up) months in all patients. RESULTS: At the last follow-up, a significant reduction of the PFVH (11.3 ± 1.7 versus 12.8 ± 2.1 at baseline, p < 0.001), the inferior scleral show distance (0.7 ± 1.0 mm versus 2.1 ± 1.1 at baseline, p < 0.001), and the MRD 2 (6.4 ± 0.9 versus 7.8 ± 1.3 at baseline, p < 0.001) occurred. The conjunctival hyperemia grading score (McMonnies) was significantly reduced (1.8 ± 0.7) at the last follow-up compared to baseline (2.6 ± 0.6, p < 0.001). No case of ectropion or entropion was observed at the last follow-up visit. CONCLUSION: In this case series, lower eyelid elevation with FL grafts as a spacer led to a significant reduction of the PFVH, MRD 2, inferior scleral show distance, and conjunctival hyperemia. No severe surgery-related complications occurred.

Nonsurgical treatment for upper eyelid retraction in patients with inactive Graves' orbitopathy.

PURPOSE: To evaluate the effectiveness of incobotulinumtoxinA (Xeomin®) in treating upper eyelid retraction in patients with Graves orbitopathy (GO) initially scheduled for surgery via two different application sites. METHODS: This is a comparative, prospective study, conducted at the Department of Ophthalmology, Medical School, University Hospital Centre Zagreb, EUGOGO site (EUropean Group On Graves' Orbitopathy) in Croatia from January 2020 till January of 2021 in accordance with national health headquarter recommendations. All patients were classified as inactive with marked eyelid retraction and randomly divided into groups according to application sites. Group A underwent transconjunctival application (18 eyes) and group B transcutaneous application (20 eyes) of incobotulinumtoxinA. The primary end point of this study was lowering the eyelid, to alleviate anterior eye segment symptoms and achieve acceptable aesthetic appearance until surgery becomes available. RESULTS: There were no nonresponders and we found no statistically significant difference in the degree of lowering the eyelid between the two application sites. Following rules for avoiding spread of SARS-CoV-19, none of the patients included in this study were infected. Moreover, participants reported diminishing of anterior eye segment irritation and improved aesthetics. CONCLUSION: Treatment of inactive GO patients with incobotulinumtoxinA for upper eyelid retraction is efficient and safe and can be used as an adjuvant treatment while patients wait for surgery, by alleviating symptoms and improving the level of aesthetic satisfaction without causing a threat to anterior eye segment and visual function. The study showed that effect of treatment was the same, whether we applied the toxin transconjunctivaly or transcutaneously.
