La ptosis palpebral es una de las patologías más frecuentes en la consulta de oftalmología, tanto en urgencias como en el ámbito ambulatorio. El trauma del párpado superior puede provocar ptosis o retracción o una combinación de ambos. En este tipo de ptosis palpebral, su resolución mediante tratamiento quirúrgico, existiendo múltiples alternativas de procedimientos que se decidirá de acuerdo con la causas que las originan, así como la severidad de la ptosis. En este trabajo es a propósito de un caso clínico en el cual nos encontramos una paciente con ptosis palpebral traumática recidivante, utilizándose suspensión frontal con aponeurosis de músculo temporal, realizándose una variación de la técnica de Crawford disminuyendo la probabilidad de nueva recidiva

Palpebral ptosis is one of the most frequent pathologies in the ophthalmology consultation, both in the emergency room and in the outpatient setting Trauma to the upper eyelid can cause ptosis or retraction or a combination of both. In this type of eyelid ptosis its resolution by surgical treatment, there are multiple alternatives of procedures that will be decided according to the causes that originate them, as well as the severity of the ptosis, in this work is about a clinical case in which we find a patient with Recurrent Traumatic Palpebral Ptosis, using frontal suspension with aponeurosis of temporal muscle, performing a variation of the Crawford Technique decreasing the probability of recurrence.

Frontalis muscle flap suspension surgery for the treatment of blepharoptosis based on the anatomical study of the frontal muscle nerve in the third of the eyebrow / Cirugía de suspensión del colgajo muscular frontal en el tratamiento de blefaroptosis basado en el estudio anatómico del nervio del músculo occipitofrontal en el tercio de la ceja

The aim of this study was to investigate the course of the supraorbital nerve and temporal branch of the facial nerve, and to verify the clinical security of cutting the frontalis muscle flap to treat blepharoptosis in one-third of the eyebrow. Twenty cadavers were dissected. The relationship of the supraorbital nerve and the course of the frontotemporal branch of the facial nerve with the head and neck muscles was evaluated. Forty patients underwent clinical frontal muscular flap suspension surgery for the treatment of blepharoptosis. The postoperative curative and complication rates were determined. The courses of the supraorbital nerve and frontotemporal branch of the facial nerve were observed to determine a relatively safe area in one-third of the eyebrow. The average width of the zone was 25.0±3.5 mm. In forty cases, satisfactory results were achieved in correcting blepharoptosis by cutting the frontal muscular flap in the middle of eyebrow within the wide range of 17±2.1 mm. No secondary sensory and motor dysfunctions occurred. One-third of the eyebrow (eyebrow center, within 17±2.1 mm) was a relatively safe area and allowed for the prevention of damage to the temporal branch of the facial nerve inside the supraorbital nerve and supraorbital artery and the outer frontotemporal branch of the facial nerve.

El objetivo de este estudio fue investigar el curso del nervio supraorbital y la rama temporal del nervio facial, para verificar la seguridad clínica de cortar el vientre frontal del músculo occipitofrontal (colgajo de músculo frontal) para tratar la blefaroptosis en un tercio de la ceja. Veinte cadáveres fueron disecados. Se evaluó la relación del nervio supraorbital y el curso de la rama temporal del nervio facial con los músculos de la cabeza y cuello. Cuarenta pacientes fueron sometidos a la cirugía de confección del colgajo del músculo frontal para el tratamiento de la ptosis palpebral. Se determinaron las tasas de curación y de complicaciones postoperatorias. Se observaron los cursos del nervio supraorbital y la rama temporal del nervio facial para determinar un área relativamente segura en un tercio de la ceja. El ancho medio de la zona fue 25,0±3,5 mm. En cuarenta casos, se lograron resultados satisfactorios en la corrección de la blefaroptosis con el colgajo del músculo frontal en la mitad de la ceja en un rango de 17±2,1 mm. No se produjeron disfunciones sensoriales o motoras secundarias. El tercio de la ceja (centro del entrecejo, dentro de 17±2,1 mm) es una zona relativamente segura y permite la prevención de daños al ramo temporal del nervio facial ubicada medial al nervio supraorbitario y a la arteria supraorbitaria, además del ramo temporal lateral del nervio facial.

Palpebral position interdependence in blepharoptosis: comparison of the effect of instillation of 10% phenylephrine drop and digital lifting / Interdependência na posição palpebral em ptose palpebral: comparação do efeito de instilação de colírio de fenilefrina 10% e o teste de elevação digital da pálpebra

Purpose: To quantify and compare the effects of instillation with 10% phenylephrine and digital lifting on the contralateral upper eyelid of patients with involutional bilateral blepharoptosis. Methods: The present prospective clinical study involved patients with involutional bilateral blepharoptosis who underwent two tests: 1) digital lifting of the more ptotic eyelid and observation of the effect on the contralateral eyelid and 2) instillation of two drops of 10% phenylephrine in the more ptotic eye and observation of the effect on the contralateral eyelid. Patients were filmed before and 5, 10, and 15 min after instillation, and the resulting images were analyzed to obtain eyelid measurements. The results were tested using a linear mixed-effects model. Results: A total of 27 patients, ranging from 52 to 82 years of age (mean age 68.51 ± 8.21 years), 24 (88.88%) of whom were women, were included in the present study. In eyes that received instillation, the marginal distance reflex-1 (MDR1) values increased from baseline (1.21 ± 0.60 mm) until 10 min after instillation, then remained statistically unchanged until 15 min after instillation (2.42 ± 0.90 mm). Significant differences were observed in the contralateral eye of the group that underwent digital lifting (1.51 ± 0.53 mm - 1.63 ± 0.56 mm) and in the contralateral eye of the group that underwent 10% phenylephrine instillation (1.38 ± 0.54 mm - 1.63 ± 0.56 mm); p=0.02 and p<0.01, respectively. Conclusion: In all eyes, 10% phenylephrine elevated the upper eyelid, with improved eyelid height at 10 min after instillation. Significant differences were observed in the height of the contralateral eyelid when compared before and after each intervention in each group; however, this difference was very small and nearly undetectable by conventional clinical evaluation in the digital lifting group. However, the 10% phenylephrine eye-drop test resulted in substantial changes in MDR1 values ...

Objetivo: Quantificar e comparar o efeito da instilação do colírio de fenilefrina 10% com o levantamento manual da pálpebra superior contralateral de pacientes com ptose palpebral bilateral involucional. Métodos: Estudo clínico e prospectivo de pacientes com ptose palpebral bilateral involucional submetidos a dois testes: 1) elevação manual da pálpebra mais ptótica e observação do efeito da intervenção na pálpebra contralateral; e 2) a instilação de duas gotas de colírio de fenilefrina 10% no olho mais ptótico e observação do efeito da intervenção na pálpebra contralateral. Os pacientes foram filmados antes e 5, 10 e 15 minutos após a instilação. Os resultados foram analisados estatisticamente com o modelo linear de efeitos mistos. Resultados: O estudo incluiu 27 pacientes com idade entre 52-82 anos (68,51 ± 8,21), 24 dos quais eram do sexo feminino (88,88%). Em olhos submetidos a instilação do colírio, os valores da DMR1 (distância marginal reflexo) aumentaram da linha de base (1,21 ± 0,60 mm) até os 10 min, em seguida, manteve-se estatisticamente estável até 15 min (2,42 ± 0,90 mm). Diferenças significativas foram observadas nos olhos contralaterais, independentemente do levantamento manual da pálpebra (1,51 ± 0,53 mm - 1,63 ± 0,56 milímetros) e da instilação do colírio de fenilefrina 10% (1,38 ± 0,54 mm - 1,63 ± 0,56 mm), p=0,02 e p<0,01 respectivamente. Conclusões: Em todos os olhos, a instilação do colírio de fenilefrina 10% mostrou um aumento gradual do valor de distância marginal reflexo até os 10 min. Nos olhos contralaterais houve diminuição do valor de distância marginal reflexo, independentemente do teste realizado, porém as mudanças que ocorrem na posição da pálpebra contralateral, durante o teste da elevação manual, são muito pequenas e difíceis de serem detectadas no exame clínico convencional. Enquanto isso, o teste de colírio de fenilefrina 10% produziu mudanças substanciais nos valores distância marginal reflexo nos ...

Blefaroplastia: elevação transpalpebral das sobrancelhas / Blepharoplasty: transpalpebral brow elevation

Introdução: A descida das sobrancelhas faz parte do processo natural de envelhecimento do terço superior da face. A ação da musculatura glabelar é uma das causas desta ptose e de outros sinais de envelhecimento. Estes sinais devem ser diagnosticados e tratados de maneira adequada durante os procedimentos de blefaroplastia sob pena de piora da ptose e de resultado não satisfatório. Métodos: Ao longo dos últimos 17 anos, um total de 246 pacientes, portadores de alterações do terço superior da face e com indicação de blefaroplastia, foram submetidos à elevação transpalpebral das sobrancelhas pela técnica de McCord modificada, mediante ampla dissecção, maior número de pontos de fixação e miomectomias dos músculos corrugadores e prócerus. Os pacientes foram acompanhados com avaliações ambulatoriais e com registros fotográficos nos 6 e 12 meses de pós-operatório. Resultados: A intercorrência mais comum foi a parestesia temporária da região frontal e do couro cabeludo. Não ocorreram casos de hematomas pós-operatórios. Ao longo do tempo foram observados resultados consistentes, com manutenção da elevação das sobrancelhas e diminuição efetiva da ação da musculatura glabelar, sem cicatrizes no couro cabeludo. Conclusões: A elevação transpalpebral de sobrancelhas, associada à miomectomia glabelar, mostra-se uma alternativa adequada, segura e efetiva para tratamento dos sinais de envelhecimento do terço superior da face.

Introduction: The brows lowdown naturally occur as an aspect of the aging upper face process. The glabelar muscular action is one cause of this ptosis and also of others aging signs. These signs must be adequately treated during the blepharoplasty, to avoid the penalty of a limited final result. Methods: Along of the last 17 years, a total of 246 patients with aesthetic problems of the upper face and with blepharoplasty indication, were submitted to a transpalpebral browlift by modified McCord technique, based in a extended dissection, more fixation stitches and prócerus and corrugators muscles miomectomy. Out patients follow-up were in ambulatory conditions with photographic records after 6 and 12 months. Results: The most common intercurrence was a transient parestesia of the frontal region and of the scalp. No postoperative hematomas were registered. The results were consistent with maintenance of the eyebrows elevation and the effective reduction of the glabelar muscles action, without the necessity of any type of coronal incision. Conclusions: The transpalpebral brow elevation associated with glabellar myomectomy shows to be an adequate option, by its safe and effective procedures for the treatment of the upper face aging signs.

Plicatura e reinserção da aponeurose do músculo levantador da pálpebra superior com sutura contínua na correção cirúrgica da ptose palpebral leve e moderada-experiência pessoal / Plication and reinsertion of the aponeurosis of the lifting muscle of the upper eyelid with continuous suture in the surgical correction of light and moderate eyelid ptosis - personal experience

Introdução: A blefaroptose ou ptose palpebral caracteriza-se pelo posicionamento anômalo da pálpebra superior em relação à sua posição normal, que é de 1 a 2 mm abaixo do limbo superior da íris; pode variar, apresentando desde uma queda discreta, até a oclusão total da fenda palpebral. Em geral, trata-se de deficiência muscular ou nervosa, de etiologia congênita ou adquirida, que resulta na impossibilidade de elevação completa da pálpebra superior, podendo também ocorrer por desinserção aponeurótica. Apresenta-se neste trabalho a tática da sutura contínua da aponeurose do músculo levantador ao tarso, ou mesmo na sua plicatura, para o tratamento da ptose leve ou moderada. Métodos: No período de 2006 a 2012, foram realizadas 26 cirurgias, abordando a aponeurose do músculo levantador com encurtamento na relação 4:1, usando sutura contínua em duplo sentido, finalizando-a com ponto em formato de oito. Resultados: Em 88,32% dos casos, os resultados foram bons e, em 11,68%, regulares. Apenas um caso evoluiu com retração na pálpebra superior, elevando o sulco palpebral. Observou-se correção incompleta, com ptose residual de 2 a 4 mm em 2 casos, os quais foram submetidos a revisão cirúrgica após 6 meses.

Introduction: Blefaroptose or eyelid ptosis is characterized by the anomalous positioning of the upper eyelid in relation to its normal position, which is 1 to 2 mm below the upper margin of the iris. It can vary from a slight descent to a total occlusion of the eyelid slit. In general, whether caused by a muscular or nerve deficiency, congenital or acquired, it results in the impossibility to use the muscle to raise the eyelid. It can also occur due to the detachment of the aponeurosis. Presented in this study is the tactic of continuous suture of the aponeurosis of the lifting muscle at the tarsus or at its foldings, for the treatment of light or moderate ptosis. Methods: In the period from 2006 to 2012, we analyzed 26 eyelids submitted to surgical treatment. 24 were operated upon, addressing the aponeurosis of the raising muscle with a shortening in the relation of 4:1 and, in 2 cases, with the reinsertion of the aponeurosis in the raising muscle of the eyelid, using continuous two-way suture completing the same with a stitch in a figure eight. Results: In 88.32% of the cases, the results were considered good, and in 11.68% satisfactory.

Ophthalmic presentation of relapsed HTLV1- associated adult T-cell leukaemia lymphoma (ATLL) in a Trinidadian man.

The ophthalmic presentation of relapse in a patient with human T-lymphotropic virus type 1 (HTLV1) associated adult T-cell lymphoma leukaemia is described. Epidemiology, clinical features and therapeutic options are briefly reviewed. Antenatal screening and inclusion of HTLV1 in the differential diagnosis of inflammatory and neuromuscular eye conditions should be considered in endemic regions.

Neuroimaging features in congenital trichomegaly: the Oliver-McFarlane syndrome.

A 23-year-old woman presented to our hospital with 9 months history of progressive ataxia, visual loss since childhood due to retinitis pigmentosa and primary amenorrhea. On examination, there were also sparse scalp hair, very long and curled upwards eyelashes and short stature. Oliver-McFarlane syndrome was suspected. Brain MRI disclosed cerebellar atrophy and hyperintense signal in corticospinal tracts on FLAIR and T2-weighted images. Therefore, brain imaging must be thoroughly investigated in patients with suspected Oliver-McFarlane syndrome, in order to determinate whether cerebellar atrophy and hyperintense signal in corticospinal tracts are part of this neurological condition.

Palpebral position interdependence in blepharoptosis: comparison of the effect of instillation of 10% phenylephrine drop and digital lifting.

PURPOSE: To quantify and compare the effects of instillation with 10% phenylephrine and digital lifting on the contralateral upper eyelid of patients with involutional bilateral blepharoptosis. METHODS: The present prospective clinical study involved patients with involutional bilateral blepharoptosis who underwent two tests: 1) digital lifting of the more ptotic eyelid and observation of the effect on the contralateral eyelid and 2) instillation of two drops of 10% phenylephrine in the more ptotic eye and observation of the effect on the contralateral eyelid. Patients were filmed before and 5, 10, and 15 min after instillation, and the resulting images were analyzed to obtain eyelid measurements. The results were tested using a linear mixed-effects model. RESULTS: A total of 27 patients, ranging from 52 to 82 years of age (mean age 68.51 ± 8.21 years), 24 (88.88%) of whom were women, were included in the present study. In eyes that received instillation, the marginal distance reflex-1 (MDR1) values increased from baseline (1.21 ± 0.60 mm) until 10 min after instillation, then remained statistically unchanged until 15 min after instillation (2.42 ± 0.90 mm). Significant differences were observed in the contralateral eye of the group that underwent digital lifting (1.51 ± 0.53 mm - 1.63 ± 0.56 mm) and in the contralateral eye of the group that underwent 10% phenylephrine instillation (1.38 ± 0.54 mm - 1.63 ± 0.56 mm); p=0.02 and p<0.01, respectively. CONCLUSION: In all eyes, 10% phenylephrine elevated the upper eyelid, with improved eyelid height at 10 min after instillation. Significant differences were observed in the height of the contralateral eyelid when compared before and after each intervention in each group; however, this difference was very small and nearly undetectable by conventional clinical evaluation in the digital lifting group. However, the 10% phenylephrine eye-drop test resulted in substantial changes in MDR1 values in the treated and contralateral eyes, indicating clinical and statistical efficiency.

Tratamento de ptose palpebral congênita pela técnica de Lester Jones / Treatment of congenital ptosis by using the Lester Jones technique

A ptose palpebral ou blefaroptose caracteriza-se pela disfunção, ou inabilidade do paciente em realizar a abertura da fenda palpebral de maneira normal. Geralmente é decorrente do acometimento do músculo levantador da pálpebra; a forma congênita ocorre em 60% a 70%. No presente trabalho é descrito um caso de ptose palpebral congênita moderada em uma paciente de nove anos, com boa função do músculo levantador da pálpebra, em olho esquerdo. A paciente foi submetida a tratamento cirúrgico pela técnica de Lester Jones, indicada nos casos de ptose de grau moderado, apresentando um resultado estético e funcional satisfatório.

Palpebral ptosis or blepharoptosis is characterized by the dysfunction or inability of the patient to normally open the palpebral fissure. Usually, it is due to the involvement of the eyelid levator muscle. The congenital form occurs in 60%-70% of cases. In this study, we describe a case of moderate congenital palpebral ptosis in a 9-year-old patient who presented with a good eyelid levator muscle function in the left eye. The patient underwent surgical treatment with the Lester Jones technique, as indicated for cases of moderate ptosis, and achieved satisfactory aesthetic and functional results.

Fenômeno de Marcus Gunn recidivado: relato de caso e revisão bibliográfica / Surgical treatment of relapsed Marcus Gunn syndrome: a case report and literature review

INTRODUÇÃO: O fenômeno de Marcus Gunn é uma ptose congênita rara e pouco conhecida, de origem neurogênica, de fisiopatogenia ainda não esclarecida. Os autores relatam um caso de ptose acentuada e recidivada após quatro correções cirúrgicas, e fazem uma breve revisão bibliográfica. RELATO DE CASO: Adulto jovem de 19 anos, sexo masculino, foi submetido a quatro tentativas de correção de ptose palpebral a direita em outros serviços, sem diagnóstico da origem da ptose congênita. O paciente apresentava abertura palpebral do olho direito ao abrir a boca, ao lateralizar o olhar para o lado ipse-lateral, e ao fechamento do olho contra-lateral. A última cirurgia foi realizada 2 anos antes, com posicionamento e fixação de fitas de silicone. O paciente não apresentava nenhum déficit neurológico ou visual. Foi submetido à cirurgia para remoção das fitas de silicone anteriormente posicionadas, confecção de enxertos em fita de técido fibroconectivo da fáscia lata do membro inferior direito, miectomia do musculo elevador da pálpebra ptosada, fixação dos enxertos da fáscia lata na borda superior do tarso com tração e fixação ao musculo frontal ipsilateral. Evoluiu com movimentos sincrônicos das pálpebras bilateralmente, e sem recidiva do ptose até o presente momento.

INTRODUCTION: Marcus Gunn syndrome is a rare and little known congenital ptosis of neurogenic origin. Its physiopathological mechanism has not been clarified. The authors report a case of pronounced ptosis that relapsed after four surgical corrections, along with a brief literature review. CASE REPORT: A 19-year-old young adult underwent four surgical corrections of the right palpebral ptosis in other services, without a definite diagnosis of the origin of the congenital ptosis. The patient showed eyelid opening in the right eye on opening the mouth, when the eye is lateralized to the ipsilateral side, and with contralateral eye closure. The last surgery was performed 2 years prior, during which silicone bands were placed and fixated. The patient did not present any visual or neurological deficit. He underwent surgery in order to remove the silicone bands that were previously placed, to prepare the strip grafts made of fibrous connective tissue from the fascia lata of the right inferior limb, and to perform myectomy of the levator muscle of the palpebral ptosis, fixation of the fascia lata grafts at the upper edge of the tarsus with traction and fixation to the ipsilateral frontal muscle. The patient progressed with synchronic movements of the eyelids bilaterally, and without relapse of the ptosis until the present date.

Sinquinesis óculomotora: dos casos de pacientes excepcionales / Oculomotor synkinesis: two cases excepcional patients

Las sinquinesis son movimientos simultáneos o coordinados en secuencia de mivimientos de músculos suplidos por diferentes nervios o por ramas independientes del mismo nervio que ocurren luego de la recuperación de una lesión axonal periferica; son debidos a la dirección errónea ("misdirection") que toman algunos axones hacia otros músculos que no constituyen su objetivo o blanco; así, cuando el paciente intenta mover algunos músculos, ocurren contracciones involuntarias en otros, no esperadas anatómicamente. Es una suerte de recableado mal realizado y confuso. En las dos pacientes que constituyen nuestro informe, ocurrieron alteraciones óculomotoras excepcionales. En la primera de 60 años portadora de un aneurisma gigante del senocavernoso izquierdo, la sinquinesis nerviosa aberrante ocurrió entre los nervios craneales tercero y sexto. En la segunda de 22 años a quien se resecó un osteocondroma gigante de la fosa media derecha, desarrolló una parálisis total del tercer nerviocraneal con sinquinesis trigémino-oculomotora entre el músculo pterigoideo derecho y el elevador del párpado superior; así como también entre el tercero (recto inferior) y sexto nervios (recto externo) ipsolateral. Se revisa la literatura al respecto.

Synkinesis are simultaneous or coordinated sequential movements of muscles that are supplied by different nerves or have independent nerve branches. They occur after the recovery a peripheral axonal injury. They are due to axons taking a wrong direction ("misdirection") towards muscles that do not constitute their objetives or targets. Thus, when the patient attempts to move a muscle, other muscles show anatomically unexpected involuntary contractions. It is a sort of confusing rewiring. Our report is based on the exceptional oculomotor alterations that occurred in two patients. In the first patient, a 60 years-old female carrying a giant aneurysm of the left cavernous sinus, the aberrant nerve synkinesis ocurred between the third and sixth cranial nerves. In the second patient, a 22 year-old female to whom was resected a giant osteochondroma of the right middle fossa, developed a total paralysis of the third cranial nerve with trigeminal oculomotor synkinesis between the right pterygoid muscle and the elevator of the upper eyelid; as well as between the inferior rectus and ipsilateral external rectus. We review the literature on the subject.

Diminuição da função do músculo levantador da pálpebra superior em pacientes submetidos à cirurgia de ptose palpebral involucional e dermatocálase / Decrease of upper eyelid levator muscle function after involutional ptosis and dermatochalasis surgery

OBJETIVO: Avaliar a diferença da função do músculo levantador da pálpebra superior (FMLPS), distância margem reflexo (DMR1) e altura do sulco palpebral (AS) antes e depois da cirurgia de blefaroplastia superior associada à correção de ptose palpebral. MÉTODOS: Quarenta e quatro pacientes com blefaroptose e dermatocálase foram incluídos. Intervenção: exploração do tendão do músculo levantador da pálpebra superior (MLPS) durante a blefaroplastia, em portadores de blefaroptose e dermatocálase. Nos casos de desinserção, o tendão foi refixado ao tarso. Desfechos analisados: foram analisados de forma bilateral a diferença entre FMLPS, DMR1 e AS antes e depois da intervenção. A dependência entre os olhos foi corrigida por meio de equações de estimativa generalizada. Foi utilizada a correlação de Pearson para quantificar a dependência entre os olhos para FMLPS, DMR1 e AS. RESULTADOS: Houve diferença significante entre as medidas de FMLPS antes e depois da cirurgia, havendo redução da excursão do MLPS após a cirurgia, diminuindo, em média, 1,1 mm (P<0,001). As medidas pré e pós-operatória de DMR1 e AS foram estatisticamente diferentes, sendo que a DMR1 aumentou, em média, 1,6 mm e a AS diminuiu, em média, 3,97 mm (P<0,001) após a cirurgia. Houve correlação significante entre os olhos para todas as variáveis propedêuticas antes e depois da cirurgia. As correlações pré-operatórias foram mais fortes no grupo sem cirurgia prévia. O mesmo foi encontrado para a correlação quanto ao grau de desinserção nos dois olhos (P>0,01). CONCLUSÃO: A função do músculo levantador da pálpebra superior diminui após a cirurgia para a correção da ptose.

PURPOSE: To evaluate the differences between upper eyelid levator muscle function (UELMF), margin reflex distance (MDR1), and eyelid crease height (ECH) before and after ptosis and dermatochalasis surgery. METHODS: Forty-four patients with blepharoptosis and dermatochalasis were enrolled. Intervention: An exploration of the levator tendon (LT) during a blepharoplasty procedure in patients with blepharoptosis and dermatochalasis and in case of its disinsertion, the tendon was reattached to the tarsus. Measured outcome: The differences between UELMF, MDR1, ECH before and after surgery were evaluated bilaterally. Dependency between both eyes was corrected by generalized estimating equations. Pearson correlation was used to evaluate the dependency of the two eyes regarding UELMF, MDR1 and ECH. RESULTS: There was a statistical significant difference between the measures of UELMF before and after surgery with excursion decreasing by a mean value of 1.1 mm after the procedure (P<0.001). Measures of MDR1 showed an increase by a mean of 1.6 mm and ECH decreased by a mean of 3.97 mm (P<0.001). We found a significant correlation between both eyes for all analyzed eyelid variables, both before and after surgery. Correlation before surgery was stronger for the group without previous surgery. The same results for correlation were found for the amount of disinsertion (P>0.001). CONCLUSIONS: Upper eyelid levator muscle function decreases after ptosis surgery.

MÉTODOS: Vinte e duas amostras de músculo levantador da pálpebra superior, provenientes de portadores de ptose congênita, foram avaliadas morfometricamente, com o intuito de quantificar a gordura presente nos espécimes e correlacionar este achado com características como idade, sexo, grau de ptose e função do músculo levantador. RESULTADOS: Não houve correlação entre a quantidade de gordura encontrada no músculo levantador de portadores de ptose congênita e os dados clínicos dos pacientes estudados. CONCLUSÃO: A quantidade de gordura presente no músculo levantador da pálpebra superior, nas condições do presente estudo, não está associada com idade, sexo, grau de ptose ou função do músculo levantador. Novos estudos serão necessários para avaliar a real alteração que ocorre no músculo levantador da pálpebra de indivíduos com ptose palpebral.

PURPOSE: To quantify the fat in the levator muscle of patients with congenital ptosis, as related to clinical and epidemiological aspects of this disease. METHODS: Twenty-two levator muscle samples of the superior eyelid from patients with congenital ptosis were morphometrically evaluated with aim of establishing a relationship between the fat quantity and age, sex, ptosis degree and levator muscle function. RESULTS: According to our results the fat in the levator muscle of patients with congenital ptosis is not related to gender or epidemiologic aspects. CONCLUSION: Fat amount in the levator muscle from congenital ptosis is not related to age, sex, ptosis degree or levator muscle function. Other studies will be necessary to show the real alterations in the levator muscle related to eyelid ptosis.

Correction of eyelid anomalies in pachydermoperiostosis.

PURPOSE: Pachydermoperiostosis, or primary hypertrophic osteoarthropathy, is a rare disease, characterized by pachydermia, acropathy, and periostosis. The authors propose the surgical correction of the eyelid anomalies in one stage. METHODS: A 30-year-old patient with moderate blepharoptosis (3 mm) and increased vertical and horizontal dimensions of the upper eyelids underwent fusiform transverse excision of skin, orbicularis muscle, and tarsus; shortening of the levator palpebrae superioris apeoneurosis by 13 mm; and 8-mm-wide wedge excision. RESULTS: Histologic findings included hyperplasia of the tarso-conjunctival plate, obstructive cystic dilatation of the sebaceous glands, extensive fibrosis, and granulomatous reaction. Satisfactory functional and aesthetic results were observed after surgery. CONCLUSION: Upper eyelid anomalies in pachydermoperiostosis can be corrected in a single stage bilaterally with good results.
