Survey of ptosis practice patterns among surgeons in Asia Pacific Society of Ophthalmic Plastic and Reconstructive Surgery (APSOPRS).

OBJECTIVE: To characterize the preferred ptosis practice patterns and variations among oculoplastic surgeons in the Asia-Pacific region. METHODS: A web-based questionnaire was sent to both members and non-members registered under the Asia Pacific Society of Ophthalmic Plastic and Reconstructive Surgery (APSOPRS)'s email database. The survey included preoperative testing practices, surgical preferences for adult aponeurotic and congenital ptosis, various surgical techniques (anterior and posterior approach ptosis procedures, and frontalis sling procedures) and postoperative practices. RESULTS: A total of 386 survey invitations were sent. There was a response rate of 68.7% from respondents from 20 countries in the Asia-Pacific region. There was variation in the preoperative evaluation and management of ptosis. Anterior approach ptosis surgery (96.6%) and frontalis sling procedures (86.8%) were performed by more surgeons than posterior approach ptosis surgery (47.2%). There was a deviation from the traditional frontalis sling procedures for patients with poor levator function. CONCLUSIONS: Our survey results provide insight into the variation in the assessment and management of ptosis amongst oculoplastic surgeons in the Asia-Pacific region. It also demonstrates some differences between practice patterns in Asia-Pacific and America.

The effect of ptosis surgery on corneal topography and aberrometry.

PURPOSE: To evaluate the corneal topography and aberrometry and their changes following ptosis surgery in patients suffering from unilateral congenital blepharoptosis. METHODS: The study included 15 eyes of 15 patients with unilateral congenital blepharoptosis who underwent surgical correction through anterior levator resection. Shack-Hartmann wavefront sensor was employed to assess Zernike coefficients and root-mean-square. Computerized corneal topography, Orbscan and aberrometry were measured pre-and 3 months post-surgery in the healthy and ptotic eyes. Aberrometric changes were compared between patients with more than one diopter of astigmatism and subjects with less amount of astigmatism. Data were analyzed using the SPSS version 16. P < 0.05 was considered as significance level. RESULTS: Following anterior levator resection, the amount of astigmatism decreased. However, the difference was not statistically significant. Changes in topographic indices were not statistically significant. Regarding tomographic indices, the change in minimum keratometry was significant. The amount of change in total higher-order aberrations (HOAs) was not statistically significant. However, there was a decrease in the amount of third-order aberrations (vertical coma and vertical trefoil) which was statistically significant for vertical coma (-0.002 ± 0.001 vs. -0.08 ± 0.02 µm, P = 0.02). Comparing aberrometric changes in patients with more than 1 diopter astigmatism and less, there was a significant difference in the amount of HOA w/o Z400. CONCLUSION: Surgical correction of ptosis could reduce the ocular aberrations, despite no significant change in astigmatism. Nonaxial high-order aberrations are mostly affected probably due to the meridional effect of ptosis on the cornea.

Anterior Segmental Optical Coherence Tomography Analyses of Severe Corneal Irregular Astigmatism following Blepharoptosis Surgery.

We report a case of severe irregular corneal astigmatism resulting from delayed diagnosis of suture exposure following blepharoptosis surgery. An 81-year-old man who had bilateral blepharoptosis surgery and two revisions on his right eye before he complained foreign body sensation (FBS) and blurred vision of his right eye. The visual acuity was 0.4 and the MRD1 was 1 mm for his right eye. A very severe corneal astigmatism of 7.7D, eccentricity of 0.53, corneal thinning, and higher order aberration (HOA) of 3.346 µm was found. Scratch-like lesions on the upper cornea suggested the presence of suture exposure; however, no sutures were found by the previous physicians and at our fist ⇒ first examination. With greater effort, a large conjunctival fold on the back of upper tarsus was turned over to reveal 2 interrupted sutures protruding the palpebral conjunctiva. The sutures were removed, and the FBS quickly disappeared. However, the patient's blurred vision persisted. His right eye's visual acuity was 0.6, and the astigmatism (6.8D), eccentricity (0.72), and HOA (2.993 µm) were comparable to that before suture removal. Early diagnosis of suture exposure is critical to avoid severe complications and vision impairment. Attention should be paid to large conjunctival folds especially in re-operated cases.

Visual field changes in glaucoma patients after blepharoptosis surgery.

PURPOSE: To examine changes in parameters of the visual field test before and after blepharoptosis surgery in patients with glaucoma. METHODS: Twenty-three eyes of 14 glaucoma patients who underwent blepharoptosis surgery at Toyama University Hospital between July 2015 and September 2020 were included in this study. Pre- and post-operative values for the mean deviation (MD), pattern standard deviation (PSD) and total deviation (TD) of the upper or lower hemi-visual field in the Humphrey visual field test, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and margin reflex distance (MRD)-1 were compared. RESULTS: MRD-1 showed a significant improvement after blepharoptosis surgery (preoperative MRD-1: 1.0 ± 0.82 mm, postoperative MRD-1: 3.26 ± 0.66 mm, p < 0.001). There were no significant differences in BCVA, IOP, MD and PSD values before and after surgery. On the other hand, there was a significant improvement in the superior TD (preoperative: -11.29 ± 6.57 dB, postoperative: -9.88 ± 7.31 dB, p = 0.044) although no significant difference was detected in the inferior TD postoperatively. The preoperative parameters of 2 groups (improvement and non-improvement groups of postoperative superior TD) were compared. Preoperative MD and superior TD were significantly lower in the improvement group (p = 0.03, p = 0.004, respectively), although there was no significant difference in preoperative PSD and inferior TD between the two groups. CONCLUSION: In glaucoma patients, blepharoptosis may interfere with accurate visual field assessment, especially of superior TD.

Corneal topographic changes after blepharoptosis surgery in patients with deepening of the upper eyelid sulcus.

PURPOSE: We analyzed the corneal topography before and after blepharoptosis surgery and examined whether there was a difference in the corneal topographic changes with and without deepening of the upper eyelid sulcus (DUES). STUDY DESIGN: Retrospective study. METHODS: A total of 23 eyes of 23 patients (6 men and 17 women) were enrolled in this study. The patients were divided into two groups according to the presence or absence of DUES, and their clinical characteristics were compared. RESULTS: There were no significant differences between the DUES (n = 9) and non-DUES (n = 14) groups in any of the parameters examined before blepharoptosis surgery, including age, best-corrected visual acuity (BCVA), margin reflex distance-1 (MRD-1), spherical equivalent, average keratometry (AveK), cylindrical power (CYL), corneal higher order aberrations (HOAs) and central corneal thickness (CCT). In the non-DUES group, BCVA, spherical equivalent, AveK, CYL, and CCT were not significantly different between before and after surgery. On the other hand, in the DUES group, BCVA, spherical equivalent, and CCT were not significantly different before or after surgery, however, AveK, CYL and HOAs showed significant decreases after surgery. In addition, related to the post-surgical changes in CYL, the DUES group had a higher rate of reduced CYL. CONCLUSION: It is expected that in eyes with DUES blepharoptosis surgery can reduce AveK, CYL and HOAs in association with postoperative corneal flattening, and that will contribute to improvements in visual function.

Outcomes of Early Correction of Congenital Myogenic Ptosis Using Transconjunctival Levator Plication.

INTRODUCTION: Early correction of congenital ptosis may be indicated due to a risk of amblyopia or because of an abnormal head tilt. One of the main problems, of planning ptosis surgery in very young children, is the inability to measure the levator function. AIM: The aim of the article was to analyze the early correction of congenital myogenic ptosis. METHODS: This was a retrospective, interventional, case series study, conducted on 12 eyes of 12 patients with unilateral, mild to moderate, congenital myogenic ptosis. Surgical correction of ptosis was performed by transconjunctival levator muscle plication. Pre- and postoperative measurements of the upper lid margin to central corneal reflex (MRD1) and upper lid skin crease height (UEC) were obtained, as well as the presence or absence of a reaction to topically applied phenylephrine 2.5% solution. RESULTS: The mean age of the patients was 29.83 months (range 14-45 months). A negative phenylephrine test was noted in only 3 (25%) of cases. Equalization of upper lid height was achieved in 6 (50%), and a hypocorrection of up to 1 mm was noted in 4 (33%) of patients. There was only 1 hypercorrection of 1 mm, noted in the first postoperative month. In one case of hypocorrection of 2 mm, the height of the lid dropped between the 1 and 3 months follow up. Subsequent revision surgery was performed, with a good outcome. With regard to the upper lid skin crease height (UEC), the mean preoperative difference in relation to the contralateral (non-operated) lid, was 2.16 mm, whereas the average postoperative or final difference was 0.41 mm. CONCLUSION: Correction of myogenic ptosis in small children, using transconjunctival levator plication, in whom levator function cannot be measured, may have a satisfactory postoperative outcome.

Simultaneous posterior eyelid ptosis repair and strabismus surgery: a single-stage approach / Cirurgia reparadora simultânea de blefaroptose posterior e de estrabismo: abordagem de estágio único

ABSTRACT Purpose: Blepharoptosis with coexisting strabismus can be observed in adults, and both these conditions affect cosmetic appearance and have psychosocial effects. Both also commonly require surgery, which is typically performed using a sequential approach. This study aimed to evaluate the efficacy of simultaneous Müller's muscle-conjunctival resection with or without tarsectomy and strabismus surgery in adult patients with ptosis and coexisting strabismus. Methods: Patients with ptosis and coexisting strabismus who underwent simultaneous Müller's muscle-conjunctival resection with or without tarsectomy and horizontal strabismus surgery were retrospectively evaluated. Analysis included measurement of the angle of deviation in prism diopters, margin reflex distance, eyelid height asymmetry, and complications following surgery. Success of Müller's muscle-conjunctival resection with or without tarsectomy was defined as a margin reflex distance of ≥3.5 and ≤5 mm with a difference between the two upper eyelids of <1 mm. Strabismus success was defined as alignment with ±10 prism diopters of orthotropia. Results: The patients comprised three women and five men with a mean age of 37.12 years (range, 22-62 years). The strabismus stage of the surgery was performed first in all patients. Upper eyelid symmetry outcomes were assessed as perfect (<0.5 mm) in four patients and good (≥0.5 mm, <1 mm) in four patients. Success of Müller's muscle-conjunctival resection with or without tarsectomy was achieved in six of eight patients (75%), and strabismus success was achieved in all patients. No revision eyelid or strabismus surgery was required following simultaneous surgery in any of the patients. Conclusion: Müller's muscle-conjunctival resection with or without tarsectomy combined with strabismus surgery may be an alternative approach for use in patients with ptosis and coexisting strabismus.

RESUMO Objetivo: Blefaroptose e estrabismo podem ser coexistentes em adultos e ambos afetam a aparência estética e o domínio psicossocial. Ambos também geralmente requerem cirurgia, realizada tradicionalmente em uma abordagem sequencial. O objetivo do presente estudo foi avaliar a eficácia da execução simultânea da ressecção musculoconjuntival de Müller, com ou sem cirurgia de tarsectomia, e da cirurgia de estrabismo em pacientes adultos com ptose e estrabismo coexistentes. Métodos: Foram retrospectivamente avaliados pacientes com ptose e estrabismo coexistentes submetidos simultaneamente à ressecção musculoconjuntival de Müller, com ou sem tarsectomia, e à cirurgia de estrabismo horizontal. A análise incluiu a mensuração do ângulo de desvio das dioptrias de prisma, a distância do reflexo à margem, a assimetria da altura palpebral e quaisquer complicações após a cirurgia. A ressecção musculoconjuntival de Müller, com ou sem sucesso na tarsectomia, foi considerada bem-sucedida com uma distância reflexo-margem medindo entre 3,5 e 5 mm, e uma diferença entre as duas pálpebras superiores menor que 1 mm. O sucesso da cirurgia de estrabismo foi definido como um alinhamento com ± 10 dioptrias prismáticas de ortotropia. Resultados: Os pacientes foram 3 mulheres e 5 homens, com média de idade de 37,12 anos (faixa de 22 a 62 anos). A parte de estrabismo da cirurgia foi realizada primeiro em todos os pacientes. Os resultados da simetria palpebral superior foram avaliados como perfeitos (<0,5 mm) em 4 pacientes, bons (≥0,5 mm, <1 mm) em 4 pacientes e regulares (≥1 mm) em nenhum. A ressecção musculoconjuntival de Müller, com ou sem sucesso na tarsectomia, teve sucesso em 6 dos 8 pacientes (75%) e a intervenção para o estrabismo foi bem-sucedida em todos os pacientes. Não foi necessária cirurgia de revisão da pálpebra ou do estrabismo após a cirurgia simultânea em nenhum paciente. Conclusão: A ressecção musculoconjuntival de Müller, com ou sem tarsectomia, pode ser combinada com a cirurgia de estrabismo em uma abordagem alternativa para pacientes com ptose e estrabismo coexistentes.

Tarsal buckling como complicação de correção cirúrgica de ptose congênita / Tarsal buckling as a complication of surgery to treat congenital ptosis

RESUMO O presente trabalho objetivou relatar um caso de tarsal buckling associado a prolapso conjuntival e à inversão de pálpebra superior como complicação da correção cirúrgica de ptose residual. Paciente do sexo feminino, 15 anos, portadora de ptose palpebral residual unilateral em olho direito, secundária à correção parcial da ptose palpebral congênita operada na infância. A segunda abordagem cirúrgica foi realizada com ressecção da aponeurose do músculo levantador da pálpebra superior, que evoluiu com inversão conjuntival da pálpebra superior. A fragilidade estrutural do tarso é a principal hipótese para justificar o tarsal buckling subsequente à cirurgia. Houve resolução completa do tarsal buckling, porém houve também persistência da ptose palpebral. O tarsal buckling é, portanto, uma complicação cirúrgica incomum, que pode ocorrer na correção da ptose palpebral, em que há rotação posterior da metade superior do tarso, fazendo com que este se curve verticalmente sobre seu eixo, favorecendo o prolapso conjuntival. A suspeição diagnóstica e a reabordagem cirúrgica precoce favorecem a resolução da condição e previnem possíveis complicações visuais.

ABSTRACT This paper aimed to report a case of tarsal buckling associated with conjunctival prolapse and upper eyelid inversion as a complication of surgical correction of residual ptosis. A 15-year-old female patient with unilateral residual eyelid ptosis in the right eye, secondary to partial correction of congenital blepharoptosis operated in childhood. The second surgery was performed with resection of the upper eyelid levator muscle aponeurosis, which progressed to conjunctival inversion of the upper eyelid. The structural fragility of the tarsus is the main hypothesis to justify tarsal buckling after surgery. There was complete resolution of tarsal buckling, but persistence of blepharoptosis. Tarsal buckling is an infrequent surgical complication that can occur in correction of blepharoptosis, when there is posterior rotation of the upper half of the tarsus, causing it to curve vertically on its axis and favoring conjunctival prolapse. Establishing diagnosis and early reoperation favor resolution of the condition and avoid possible visual complications.

Fifteen years of experience with frontalis suspension using polytetrafluoroethylene (Gore-Tex®) suture in blepharoptosis repair / 15 anos de experiência em suspensão frontal com fio de politetrafluoretileno (Gore-Tex®) na correção de ptose palpebral

ABSTRACT Purpose: To review the outcomes of frontalis suspension surgeries with the use of polytetrafluoroethylene in patients with blepharoptosis. Methods: A retrospective observational study analyzed the outcomes of frontalis suspension surgeries performed in a single institution from 2003 to 2018. All procedures were performed with closed incision and single pentagon techniques. Outcomes were classified as satisfactory or unsatisfactory, with satisfactory defined as a margin reflex distance of >3 mm and <1 mm between eyelids and unsatisfactory as hypocorrection, surgical complications, and asymmetry. Results: We included a total of 76 eyelids from 52 patients in our study. Within a mean postoperative follow-up of 16.8 ± 18.5 months (range, 3-95), 59 (77.6%) eyelids had a satisfactory outcome, and 17 (22.4%) were unsatisfactory (8 cases of asymmetry, 3 granulomas, 3 suture extrusions, 2 abscesses, and 1 case of cellulitis). Nine eyelids from the unsatisfactory group required reoperation. Among the patients with a follow-up of ³12 months (38 surgeries), lasting results were observed in most eyelids, except for 2 late-onset suture extrusions. Conclusion: The use of polytetrafluoroethylene in frontalis suspension surgery was shown to be predictable, safe, and lasting. Our findings support previous studies that have shown adequate functional results and low complication rates.

RESUMO Objetivo: Revisar os resultados de cirurgias de sus pensão ao músculo frontal com o uso de fio de politetrafluoretileno em pacientes com blefaroptose. Métodos: Em um estudo observacional retrospectivo, foram analisados os resultados das cirurgias de músculo frontal de uma instituição, realizadas entre 2003 e 2018. Todos os procedimentos foram realizados com incisão fechada e técnica de pentágono. Os desfechos foram classificados como satisfatórios ou insatisfatórios com definição satisfatória definida como distância margem-reflexo >3mm e <1mm entre as pálpebras e insatisfatória como hipocorreção, complicações cirúrgicas e assimetria. Resultados: Incluímos um total de 76 pálpebras de 52 pacientes em nosso estudo. Com um tempo médio de seguimento pós-operatório de 16,8 ± 18,5 meses (intervalo 3-95), 59 (77,6%) pálpebras apresentaram desfecho satisfatório e 17 (22,4%) insatisfatórios (8 casos de assimetria, 3 granulomas, 3 extrusões de sutura, 2 abscessos e 1 caso de celulite). Nove pálpebras do grupo insatisfatório necessitaram de reoperação. Entre os pacientes com seguimento ³12 meses (38 cirurgias), resultados duradouros foram observados na maioria dos casos, exceto por 2 extrusões de sutura de surgimento tardio. Conclusão: O uso de politetrafluoretileno na cirurgia de músculo frontal mostrou ser previsível, seguro e duradouro, Nossos achados corroboram com estudos prévios que mostraram resultados funcionais adequados e baixos índices de complicação.

Entrópio palpebral severo pós cirurgia de correção de ptose / Severe eyelid entropion after ptosis correction surgery

Resumo Paciente de 69 anos evoluiu com entrópio palpebral severo após cirurgia de correção de ptose palpebral pela técnica de reinserção da aponeurose do músculo levantador da pálpebra superior. Realizada reintervenção onde foi diagnosticado uma fixação da aponeurose em uma posição muito inferior e feita uma refixacação no 1/3 superior do tarso, com melhora do quadro funcional e estético com boa satisfação da paciente. Devido às suturas em topografia mais inferior, o tarso adquire forma de U em decorrência do dobramento no centro da placa tarsal e da rotação inferior da sua metade superior resultando no entrópio. Este caso ressalta a importância do cuidado quanto a localização da inserção da aponeurose do MLPS, principalmente nos paciente idosos, como forma de evitar o encurvamento vertical do tarso.

Abstract Sixty-nine (69) year old patient with severe upper eyelid entropion following surgical correction of ptosis through levator muscle aponeurosis advancement and reinsertion. The aponeurosis advancement appeared to be much lower than typically intended, and surgical repair was performed via aponeurosis re-fixation into the superior 1/3 of the tarsal plate, with subsequent improvement in the aesthetic and functional outcome, and a satisfied patient. Due to the inferiorly located tarsal sutures, the tarsal plate acquires a U-shape due to a central fold and an inferior rotation of its upper half, resulting in entropion formation. This case highlights the importance of taking great care when advancing the levator muscle in ptosis due to levator aponeurosis dehiscence, particularly in elderly patients, so as to avoid vertically folding the superior tarsal plate.

Accidental lacrimal gland removal during resection of the levator palpebrae superioris muscle / Remoção acidental da glândula lacrimal em cirurgia de ressecção do músculo levantador da pálpebra superior

ABSTRACT Accidental removal of the lacrimal gland is a rare complication of ptosis surgery. We report two children who underwent large unilateral levator palpebrae superioris resections (LPSr). After surgery, both patients developed dry eye. Post-operatively, the parents of both patients noticed no tears in the affected eye when their child cried. Computed tomography proved the absence of the lacrimal gland in the operated eye in both patients. Oculoplastic surgeons should pay close attention to the anatomy of the levator muscle and its proximity to surrounding tissues in order to avoid lesions on important orbital structures, including the lacrimal gland, and to avoid the development of long-term dry eye.

RESUMO A remoção acidental da glândula lacrimal é uma complicação rara da cirurgia de ptose. Relatamos duas crianças que foram submetidas à grandes ressecções unilaterais do músculo levantador da pálpebra superior que desenvolveram olho seco após a cirurgia. No pós-operatório, os pais notaram ausência de secreção lacrimal durante o choro no olho operado. Tomografia computadorizada de órbitas comprovou ausência da glândula lacrimal no olho submetido à cirurgia, em ambos os casos. Cirurgiões oculoplásticos devem estar atentos à anatomia do músculo levantador e estruturas relacionadas para evitar lesões em importantes estruturas orbitais como as da glândula lacrimal que podem induzir permanente olho seco.

Inferior displacement of the lower eyelid during intraoperative quantification in blepharoptosis surgery.

PURPOSE: To examine inferior displacement of the lower eyelid during eye closing in intraoperative quantification of blepharoptosis surgery. METHODS: A series of lower eyelid movements during eye closing in intraoperative quantification of blepharoptosis surgery were examined in 30 eyelids of 15 patients (6 males and 9 females; mean age 70.0 years; range 43-81 years) with bilateral aponeurotic blepharoptosis. RESULTS: Inferior displacement of the lower eyelid was observed in all eyelids examined, although the extent varied in each patient (range 2.0-4.5 mm; mean 3.2 mm). Inferior displacement occurred with upward eye movement caused by Bell's phenomenon. Many wrinkles were simultaneously observed as a result of contraction of the orbicularis oculi muscle. After maintaining the inferiorly displaced state for several seconds, 20 lower eyelids in 10 patients naturally moved superiorly to a resting position. On the other hand, 10 lower eyelids in 5 patients remained in the same inferior position for more than 5 seconds, after which we had to manually elevate them to a resting position. The eyes then moved inferiorly to their resting position with a decrease in the number of lower eyelid wrinkles. Once the patients opened their eyes, inferior displacement of the lower eyelid completely disappeared. CONCLUSIONS: Inferior displacement of the lower eyelid during eye closing increases the amount of lagophthalmos. This phenomenon needs to be considered for quantifying the intraoperative lagophthalmos level during blepharoptosis surgery.

Frontalis sling surgery: do we really need the Wright needle? / Suspensão ao músculo frontal: realmente precisamos da agulha de Wright?

ABSTRACT Purpose: The aim of this study is to describe a variation in technique of the frontalis sling surgery with silicone rods and its results, using an alternative needle with similar effectiveness to the Wright needle at a reduced cost. Methods: This was a prospective, interventional, noncomparative study of patients with severe ptosis who underwent surgical correction using a simple and modified frontalis sling surgery technique. Patients were included in this study from January 2012 to January 2014. 23 surgeries were performed on 15 patients. The minimum "follow-up" was 12 months. Results: Most patients had congenital ptosis (86%) and the average preoperative margin reflex distance 1 (MRD1) was -1.1 mm (range -3 to 0 mm). 1 week post-operation, this was 2.7 mm ( 1.8 to 3.8 mm), 1.8 mm after 1 month and 1.7 mm (1 to 2.5 mm) after one year. The satisfaction rate was 80% (12 patients). Among the dissatisfied patients, one had extrusion and infection with subsequent explantation of the wire, one had asymmetry greater than 2 mm and one had persistent lagophthalmos and punctate keratitis, with subsequent explantation of silicone. Conclusion: The use of silicone rods with tarsal fixation using an alternative needle was effective in the treatment of severe ptosis with few complication rates, a low rate of dissatisfaction and good stability of the results in the follow-up period.

RESUMO Objetivos: O objetivo deste estudo é descrever uma variação da técnica cirúrgica da suspensão ao músculo frontal com fio de silicone e seus resultados, utilizando uma agulha alternativa à agulha de Wright, com a mesma eficácia e melhor razão custo-benefício. Métodos: Foram analisados prospectivamente todos os casos de blefaroptose severa submetidos à correção cirúrgica, utilizando a técnica de suspensão ao músculo frontal modificada, no período de janeiro de 2012 à janeiro de 2014. Foram realizadas 23 cirurgias em 15 pacientes. O "follow-up" mínimo foi de 12 meses. Resultados: A grande maioria dos pacientes apresentavam blefaroptose congênita (86%), a média da distância margem reflexo pré-operatória foi de -1,1mm (-3 a 0 mm), no pós-operatório de 1 semana foi de 2,7 mm (1,8 a 3,8 mm), após 1 mês foi de 1,8 mm e após 1 ano, de 1,7mm (1 a 2,5 mm). O índice de satisfação foi de 80% (12 pacientes). Dos 3 pacientes insatisfeitos, 1 teve extrusão e infecção com posterior explante do fio, 1 apresentou assimetria maior que 2mm e 1 evoluiu com lagoftalmo persistente e ceratite puntacta, com posterior explante do silicone. Conclusão: O uso do fio de silicone com fixação tarsal usando uma agulha alternativa, se mostrou eficaz no tratamento da blefaroptose severa, com poucas complicações, baixo índice de insatisfação e boa estabilidade dos resultados no período de seguimento.

Ptose miogênica na distrofia muscular oculofaríngea / Miogenic ptosis in oculopharyngeal muscular dystrophy

A paciente apresentou quadro de ptose palpebral bilateral e disfagia, achados clínicos típicos da doença, foi submetida a tratamento cirúrgico da ptose, com bom resultado estético e funcional.

ABSTRACT The authors report a case of oculopharyngeal muscular dystrophy, an autosomal dominant genetic disease, which leads to miogenic ptosis. This patient presented bilateral palpebral ptosis and dysphagia and underwent ptosis surgical treatment, with a good functional and aesthetic result.

Transcutaneous blepharoptosis surgery - advancement of levator aponeurosis.

Ptosis surgery has seen many advances in the last few decades, the most important of which have emerged as a result of better understanding of the anatomy and physiology of the eyelid and orbit. Anterior approaches such as a levator aponeurosis advancement, tarsoaponeurectomy and posterior repair involving resection of Muller's muscle have proven to be effective in most cases. The focus of this article is a discussion of the indications, operative techniques, success rates and complications of transcutaneous levator advancement in detail.

Transcutaneous Blepharoptosis Surgery: Simultaneous Advancement of the Levator Aponeurosis and Müller's Muscle (Levator Resection).

Transcutaneous blepharoptosis surgery with simultaneous advancement of the levator aponeurosis and Müller's muscle (levator resection) is a popular surgery which is considered effective for all types of blepharoptosis except for the myogenic type. Repair of ptosis cases with good levator function yields excellent results. A good outcome can be also obtained in cases with poor levator function, however, in such cases; a large degree of levator advancement may be required, which may result in postoperative dry eyes, unnatural eyelid curvature and astigmatism. These cases are therefore better treated with sling surgery. With the right patient selection, the levator resection technique is an effective method for ptosis repair.

Transconjunctival blepharoptosis surgery: a review of posterior approach ptosis surgery and posterior approach white-line advancement.

Posterior approach blepharoptosis surgery, via the transconjunctival route, was probably the first method of surgery employed to shorten the levator palpebrae superioris (LPS) muscle. A review of the literature demonstrates how surgery has evolved since Blaskovics' first described his technique in 1923. We describe our newer method of posterior approach white-line advancement blepharoptosis repair which is now an option in the majority of aponeurotic ptosis with moderate to good levator function.

Tratamento cirúrgico da blefaroptose congênita / Surgical treatment of congenital blepharoptosis

A blefaroptose é o posicionamento inadequado da pálpebra superior, estando abaixo de sua posição normal na posição primária do olhar, a qual seria 0,5 – 2mm abaixo do limbo superior. Pode causar bloqueio parcial ou completo do campo visual superior, além do comprometimento estético. As causas são categorizadas em congênitas ou adquiridas. É considerada congênita se presente ao nascimento ou diagnosticada no primeiro ano de vida. As principais técnicas utilizadas para o tratamento da ptose congênita são a ressecção da aponeurose do músculo levantador da pálpebra superior (MLPS) e a suspensão frontal. A medida da função do MLPS é o parâmetro mais importante na escolha da técnica cirúrgica. Quando a função é fraca, a suspensão frontal é mais indicada; a ressecção supramáxima do MLPS também pode ser empregada. Acima de 4 ou 5mm de função do MLPS, prefere-se a ressecção da aponeurose. Para a cirurgia de suspensão frontal, vários são os materiais utilizados, portanto apresentamos uma comparação entre os estudos mais relevantes. Discutiremos também particularidades em casos mais complicados, como as Síndromes da Blefarofimose e de Marcus-Gunn, além de técnicas cirúrgicas menos utilizadas e as complicações relatadas.

The blepharoptosis is the improper positioning of the upper eyelid, being below its normal position in primary gaze, which is 0.5 - 2mm below the superior corneal limbus. It may block partially or completely the upper visual field, and lead to aesthetic commitment. The causes are categorized as congenital or acquired. It is considered congenital if present at birth or diagnosed during the first year of life. The main techniques used for the treatment of congenital ptosis are the resection of the levator muscle aponeurosis and the frontalis suspension. The function of the levator muscle is the most important parameter to define the surgical technique. When the function is weak, the frontalis suspension is more appropriate; the supra-maximal resection of the levator muscle may also be employed. With function above 4 or 5mm, the resection of the aponeurosis is preferred. For the frontalis suspension surgery, various materials can be used, so we present a comparison of the most relevant studies. We also discuss some characteristics in more complicated cases, such as the Blepharophimosis syndrome and the Marcus-Gunn syndrome, and surgical techniques less performed and complications reported.

Ptose palpebral causada por Paquidermoperiostose / Palpebral ptosis caused by Pachydermoperiostosis

A paquidermoperiostose é uma síndrome caracterizada por acometimento cutâneo e ósseo, e em alguns casos ocorre comprometimento palpebral leve. É uma síndrome rara, idiopática ou hereditária, com provável herança autossômica dominante de penetrância variável. Descreve-se o caso de um paciente com ptose grave por paquidermoperiostose elucidando sua fisiopatologia e conduta cirúrgica aplicada.

Pachydermoperiostosis is a rare disorder characterized by the involvement of skin and bone, and in some cases it can have a mild adverse effect in the eyelid. Although the etiology is still unclear, idiopathic or hereditary cases, in an autossomal dominant inheritance, have been reported.

Tratamento da ptose palpebral com emprego de retalho em asa do músculo orbicular / Eyelid ptosis treatment using bat flap of the orbicular muscle

Este trabalho foi realizado com o objetivo de demonstrar a possível utilização do músculoorbicular para o tratamento de ptose palpebral em casos em que não exista ação ou funçãodo músculo elevador das pálpebras, utilizando-se um retalho bipediculado do músculo orbicularpalpebral em sua porção superior em forma de “asa”, fixado à aponeurose inferiorsuperciliar do músculo frontal da face, tal avaliação foi realizada no período entre 1992 e2009.
