Objetivo: Describir los resultados funcionales de la blefaroplastia superior. Métodos: Se realizó un estudio descriptivo longitudinal prospectivo de 99 pacientes (198 párpados) con diagnóstico de dermatochalasis de párpado superior, algunos asociados a ptosis palpebral y de la ceja, en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer", en el período comprendido de febrero del año 2019 a enero de 2020. Resultados: El 85,8 por ciento fueron del sexo femenino y el 43,5 por ciento eran mayores de 62 años. Predominó la dermatochalasis del párpado superior y la ptosis palpebral en el 68,4 por ciento, así como la dermatochalasis y la ptosis palpebral severa, las cuales representaron el 47,5 y el 50 por ciento respectivamente. En el grupo de 56 a 61 años sobresalió la dermatochalasis del párpado superior y la ptosis de la ceja, con el 61 por ciento. En el 98 por ciento de los casos intervenidos se obtuvo la corrección total de la dermatochalasis del párpado superior, la corrección de la ptosis en el 86 por ciento y de la ceja en el 88 por ciento. No se presentaron complicaciones en el 94 por ciento de los párpados intervenidos. La complicación más frecuente fue el sangramiento, con el 2,5 por ciento. Conclusiones: El abordaje de la ptosis palpebral y de las cejas transblefaroplastia superior logra en la mayoría de los pacientes la corrección total de estas afecciones y de la dermatochalasis. Este procedimiento constituye una herramienta importante para el rejuvenecimiento facial(AU)

Objective: Describe the functional results of upper blepharoplasty. Methods: A prospective longitudinal descriptive study was conducted of 99 patients (198 eyelids) diagnosed with upper eyelid dermatochalasis, in some cases associated to eyelid and eyebrow ptosis. The study was carried out at Ramón Pando Ferrer Cuban Institute of Ophthalmology from February 2019 to January 2020. Results: Of the total patients studied, 85.8 percent were female and 43.5 percent were aged over 62 years. Upper eyelid dermatochalasis and palpebral ptosis prevailed with 68.4 percent, whereas severe dermatochalasis and palpebral ptosis represented 47.5 percent and 50 percent, respectively. A predominance was found of upper eyelid dermatochalasis and eyebrow ptosis in the 56-61 age group (61 percent). Total correction of upper eyelid dermatochalasis was achieved in 98 percent of the cases intervened, eyelid ptosis correction in 86 percent and eyebrow ptosis correction in 88 percent. No complications appeared in 94 percent of the eyelids intervened. The most common complication was bleeding with 2.5 percent. Conclusions: In most cases, management of palpebral ptosis and upper eyebrow transblepharoplasty achieves total correction of these disorders and dermatochalasis. The procedure is an important tool for facial rejuvenation(AU)

Síndrome de Horner: revision de la literatura / Horner´s Syndrome: literature review

Resumen El Síndrome de Horner (SH) es una condición provocada por un grupo heterogéneo de patologías. Estas tienen en común el daño de la vía simpática. La localización más común de la lesión es a nivel preganglionar, por trauma o cirugías en región cervical, torácica o ápex pulmonar. El diagnóstico es primordialmente clínico mediante la identificación de la triada de miosis, ptosis y anhidrosis. Se confirma con las pruebas para cocaína e hidroximetanfetamina. El tratamiento se lleva a cabo primero con agentes farmacológicos. Los que tienen disminución del campo visual por la ptosis o por razones cosméticas se llevan a tratamiento quirúrgico. En ese caso los abordajes operatorios recomendados para ptosis leve son el procedimiento de Fasanella-Servat, el avance de aponeurosis del elevador y en casos severos el cabestrillo frontal. El objetivo es hacer una revisión de los algoritmos diagnósticos y terapéuticos del SH para lograr un abordaje sistemático debido a las múltiples etiologías que posee.

Abstract Horner Syndrome is a condition caused by a heterogeneous group of pathologies. These have in common the damage of the sympathetic pathway. The most common location of the lesion is at the preganglional level, due to trauma or surgeries in the cervical, thoracic or pulmonary apex region. The diagnosis is primarily clinical by identifying the triad of myosis, ptosis and anhidrosis. It is confirmed with the cocaine and hydroxymethamphetamine tests. Treatment is first carried out with pharmacological agents. Those with diminished visual field due to ptosis or cosmetic reasons are undergoing surgical treatment. In this case, the recommended operative approaches for mild ptosis are the Fasanella-Servat procedure, the elevator aponeurosis advance and, in severe cases, the frontalis sling. The objective is to review the diagnostic and therapeutic algorithms of SH in order to achieve a systematic approach due to the multiple aetiologies it possesses.

Abordaje pterional transilviano con apoyo neuroendoscópico en colesteatoma cerebral, a propósito de un caso interesante / Transsilvian pterional approach with neuroendoscopic support in cholesteatoma of the brain. A propos of an interesting case

RESUMEN Los quistes epidermoides constituyen el 1 % de los tumores intracraneales y el 7 % de los del ángulo pontocerebeloso. Los colesteatomas son lesiones benignas que se originan de restos de tejidos epitelial ectodérmicos que quedan en el sistema nervioso central, al cerrarse el tubo neural entre la tercera y quinta semana de gestación. Se trata de un paciente remitido de la Consulta de Neurooftalmología con crisis de cefalea y toma de los pares craneales III, IV, V, rama oftálmica desde hace 2 semanas. Se le realizaron estudios imagenológicos donde se constató un tumor hipodenso en región silviana frontotemporal izquierdo. Se interpretó como un quiste arcnoideo. Se le aplicó un bordaje pterional transilviano con apoyo neuroendoscópico y para sorpresa del equipo quirúrgico se abordó un tumor perlado solido identificado macroscópicamente como un colesteatoma silviano. Se resecó la totalidad del tumor cerebral.

ABSTRACT Epidermal inclusion cysts constitute 1% of the intracranial tumors and 7% of the cerebellopontine angle ones.Cholesteatoma are benign lesions originated from the remains of ectodermic epithelial tissues remaining in the central nervous system when the neural tube closes between the third and fifth week of pregnancy. The case deals with a patient remitted from the Neurophthalmologic Consultation with migraine crisis and lesion on the III, IV, V cranial nerves, ophthalmologic branch, for two weeks. Image studies were carried out, showing a hypo dense tumor in the left silvian frontotemporal region. It was taken as an arachnoid cyst. A pterional trans-silvian approach with neuroendoscopic support was applied, and the surgical team was surprised when they found a solid pearly tumor that was macroscopically identified as a silvian cholesteatoma. The cerebral tumor was totally resected.

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. This study is a case report of a patient with severe blepharoptosis due to pachydermoperiostosis, which describes the surgical procedure and the physiopathology of the condition.

Trismus as a first presenting complaint in a case of myasthenia gravis.

The initial presentation of myasthenia gravis as trismus is very rare and no previous reports have been found in the literature. A 35-year-old male presented to the outpatient unit of our department with inability to clench well and to open his mouth. Physical examination revealed that he had clinical findings consistent with the signs and symptoms of myasthenia gravis. He was immediately referred to a neurologist, who confirmed that he was in an advanced stage of myasthenia gravis with severe deficit to his respiratory muscles and he was promptly treated. He is presently on a maintenance drug therapy. To our knowledge, this is the first reported case of myasthenia gravis whose initial presentation was trismus. This case presents a rare but important diagnosis that should be added to the differential diagnosis of trismus.

Manejo dinámico de la ptosis palpebral traumática / Dynamic management of traumatic eyelid ptosis

El aumento en la incidencia de traumatismos faciales secundarios a accidentes automovilísticos, agresiones en la vía pública u otras causas ha traído aparejado consecuentemente un incremento en la observación de otros cuadros clínicos, dentro de los cuales encontramos la ptosis palpebral traumática. De difícil diagnóstico en su fase inicial motivada por el edema o injuria de los tejidos, presenta a su vez dentro del trauma algunas variantes en su fisiopatología (traumática, mecánica, miogénica o pseudoptosis), las cuales es preciso conocer y diferenciar para indicar su adecuado tratamiento y el momento oportuno... Se dan pautas de tratamiento en función de la etiología y el tiempo transcurrido.

Síndrome de Kearns-Sayre: relato de dois casos / Kearns-Sayre syndrome: two case reports

Descrevem-se dois casos em que os pacientes tinham como queixa principal a baixa da acuidade visual progressiva em evolução de quatro anos e oito meses, respectivamente. O quadro clínico de oftalmoplegia externa, com alterações fundoscópicas demonstrando atrofia da retina, epitélio pigmentar e coriocapilar, levou ao diagnóstico clínico de síndrome de Kearns-Sayre. A investigação etiológica do quadro oftalmológico é fundamental, pois na maioria das vezes está associado a condições sistêmicas graves que necessitam de acompanhamento e tratamento adequados.

Two cases in which patients had progressive loss of visual acuity in four years and eight months respectively are described. Clinical examination revealed fundoscopic alterations of the retina, pigment epithelium and choriocapillaris showing marked atrophy. The clinical picture resembles Kearns-Sayre syndrome. Etiological investigation is fundamental, because most of time this condition is associated with more serious systemic complications which need specific care.

Regeneração aberrante do nervo oculomotor secundária a aneurisma intracraniano: relato de caso / Aberrant regeneration of the oculomotor nerve followed by intracranial aneurysm: case report

Relatar um caso de regeneração aberrante secundária à paralisia aguda do nervo oculomotor causada por aneurisma intracraniano. Paciente atendida em fevereiro de 2006 queixando-se de dor de cabeça acompanhada de visão dupla e queda da pálpebra no olho direito. Na avaliação da motilidade ocular extrínseca, verificou-se incapacidade da adução, da supradução e da infradução associada à blefaroptose no olho direito. Com relação à motilidade intrínseca, midríase paralítica no olho direito. Formulou-se diagnóstico de paralisia aguda de nervo oculomotor no olho direito e solicitou-se avaliação neurológica. No Departamento de Neurocirurgia, após ser diagnosticada presença de aneurisma de artéria comunicante posterior, a paciente foi submetida a tratamento cirúrgico. Em dezembro de 2006, observou-se melhora relativa da adução, mantendo a incapacidade da supradução e da infradução com blefaroptose melhorada à adução do olho direito. Com relação à motilidade intrínseca, miose no olho afetado. O diagnóstico de regeneração aberrante do nervo oculomotor pós-paralisia aguda foi formulado baseando-se na anamnese e nos exames oftalmológicos seqüenciais.

To report a case of aberrant regeneration followed by acute palsy of the oculomotor nerve caused by intracranial aneurysm. A 59-year-old patient was attended in February 2006 complaining of headache with diplopia and blepharoptosis in the right eye. At the external ocular motility exam. Aduction, supraduction and infraduction defects with blepharoptosis in the right eye were observed. Regarding the internal ocular motility, mydriasis in the right eye. Acute palsy of the oculomotor nerve in the right eye was diagnosed and neurological examination was requested. At the Department of Neurosurgery, after having diagnosed aneurysm of the posterior communicating artery, the patient was submitted to an operation. In December 2006, it improvement of the aduction was observed, supraduction and infraduction defects remained and blepharoptosis improved during aduction of the right eye. In the internal ocular motility, miosis in the affected eye. The diagnosis of the aberrant regeneration of the oculomotor nerve after acute palsy was formulated based on anamnesis and ophthalmological follow-up tests.

Síndrome de tolosa hunt: a propósito de un caso / Tolosa hunt syndrome: a purpose of a case

El síndrome de tolosa-Hunt es una oftalmoplejia dolorosa, recurrente provocada por una inflamación granulomatosa inespecífica que afecta al seno cavernoso, la hendidura esfenoidal y el apex orbitario. Se caracteriza por dolor retrocular agudo recurrente con parálisis extraocular, que generalmente afecta los nervios craneanos tercero, cuarto, quinto y sexto. Se le atribuye a una infiltración granulomatosa del apex orbitrario o en el seno cavernoso, que responde a la corticoideoterapia. Nuestro paciente consulta por enfermedad de 3 meses de evolución presenta de forma súbita cefalea de fuerte intensidad; y pulsátil acompañado de dolor de fuerte intensidad en globo ocular derecho de carácter pulsátil y progresivamente ptosis palpebral derecha. Se le instaura tratamiento con corticoides, AINES y antiglaucomatosos con poca mejoría sin recuperar amaurosis del ojo derecho. Se obtienen estudios por TAC y RNM de órbita donde se evidencia engrosamiento a nivel del seno cavernoso. Evaluado por equipo multidisciplinario de oftalmología, neurocirugía, Medicina Interna, Imagenología. Considerando que existe un predominio por el seno cavernoso. No se disponen de estudios de prevalencia o incidencia. Se ubica el síndrome de Tolosa-Hunt como la tercera causa de síndrome del seno cavernoso, superado por el trauma y los tumores.

Ptosis congénita / Congenital ptosis

Al examinar a un paciente y detectar asimetría facial por ptosis unilateral, es necesario realizar un anamnesis completa y examen físico para dilucidar si se trata de un hecho aislado o es manifestación de un trastorno neuromuscular. A los padres les preocupa además el factor estético de la ptosis por lo cual se debe explicar y estudiar precozmente para mayor tranquilidad.

Sudoriferous cyst of the orbit of adult origin after trauma.

A rare case of sudoriferous cyst of the orbit occurring in an adult, who had facial trauma, is reported. Several factors suggest its adult onset. The only other case reported in an adult is of presumed childhood origin. Very few congenital cases have been reported. A 65-year-old lady presented with recent onset of left-sided ptosis and a painless mass below the left supraorbital margin. The patient had traumatic ptosis after a road traffic accident 13 years ago. The ptosis was surgically repaired, which resulted in symmetrical palpebral apertures. Computed tomographic scan revealed a well-defined cystic mass in the anterior orbit. The mass was removed in toto by anterior orbitotomy. Histopathological examination revealed a single cyst lined by double-layered cuboidal epithelium in some areas and transitional epithelium at others. A periodic acid Schiff (PAS) positive, diastase-resistant glycocalyx lined the inner epithelium. Apical snouting suggested an apocrine nature. This confirmed a diagnosis of sudoriferous cyst.

Medida da distância reflexo margem por meio de processamento computadorizado de imagens em usuários de lentes de contato rígidas / Margin reflex distance measure by computerized image processing in rigid contact lens wearers

OBJETIVO: Apresentar um método novo, baseado no processamento computadorizado de imagens, para quantificar a distância reflexo margem (MRD). MÉTODOS: Selecionamos para o estudo pacientes do Setor de Lentes de Contato do Serviço de Oftalmologia da Santa Casa de Porto Alegre que foram divididos em dois grupos: o primeiro foi composto por pacientes usuários de lentes de contato rígidas (63 olhos) e o segundo por pacientes que foram encaminhados para adaptação de lentes de contato sem história prévia de uso das mesmas (30 olhos). Todos os pacientes foram fotografados com o auxílio de uma câmera fotográfica digital (Nikon Coolpix 4300). A distância reflexo margem foi medida por processamento computadorizado de imagens utilizando o programa Image J. Foram excluídos do estudo pacientes submetidos a cirurgias intra-oculares ou palpebrais, pacientes apresentando ptose congênita e pacientes que ao exame biomicroscópico apresentavam conjuntivite papilar gigante. RESULTADOS: O método utilizado para quantificar distância reflexo margem parece bastante simples e aparentemente mais sensível e específico. O valor médio da distância reflexo margem no grupo caso foi 2,46 mm e no grupo controle 2,72 mm. Dessa forma, observou-se uma tendência de diminuir a distância reflexo margem com o uso de lentes rígidas, embora esses dados não tenham sido estatisticamente significativos (p=0,22). Observa-se também que os valores de distância reflexo margem apresentam uma variabilidade muito maior no grupo caso (41,46 por cento) do que no controle (28,96 por cento), que se apresenta mais homogêneo. CONCLUSÃO: Esse estudo introduziu uma metodologia inovadora para medir a distância reflexo margem utilizando o processamento computadorizado de imagens. Esse método é acessível e pode auxiliar no acompanhamento da distância reflexo margem de pacientes usuários de lentes de contato, especialmente rígidas.

PURPOSE: To measure the MRD (margin reflex distance) in rigid contact lens wearers and controls by a new method, based on computerized image processing. METHOD: The patients were selected from the Contact Lens Sector of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre", and they were divided into two groups: the first was formed of rigid contact lens wearers (63 eyes) and the second of patients without previous history of contact lens wear (30 eyes). All patients were photographed with a digital camera (Nikon Coolpix 4300). The margin reflex distance was measured by a computerized image processing using the Image J program. The study excluded patients that underwent any kind of intraocular or eyelid surgery, patients with congenital ptosis and patients with giant papillae conjunctivitis. RESULTS: The method utilized to measure margin reflex distance seems simple and more accurate. The average value of the margin reflex distance in the case group was 2.46 mm and in the control group 2.72 mm. The study shows that there is a tendency of decreasing the margin reflex distance with contact lens wear although the data were not statistically significant (p=0.22). The margin reflex distance values show a greater variability in the case group (41.46 percent) than in the control group (28.96 percent), that is more homogeneous. CONCLUSION: This study introduced a new method to measure the margin reflex distance using computerized image processing. This method is accessible and could help in follow-up of the margin reflex distance in contact lens wearers, specially those rigid.

A Case of Oculomotor Nerve Palsy and Choroidal Tuberculous Granuloma Associated with Tuberculous Meningoencephalitis

We report a rare case of oculomotor nerve palsy and choroidal tuberculous granuloma associated with tuberculous meningoencephalitis. A 15-year-old male visited our hospital for an acute drop of the left eyelid and diplopia. He has been on anti-tuberculous drugs (isoniazid, rifampin) for 1 year for his tuberculous encephalitis. A neurological examination revealed a conscious clear patient with isolated left oculomotor nerve palsy, which manifested as ptosis, and a fundus examination revealed choroidal tuberculoma. Other anti-tuberculous drugs (pyrazinamide, ethambutol) and a steroid (dexamethasone) were added. After 3 months on this medication, ptosis of the left upper eyelid improved and the choroidal tuberculoma decreasedin size, but a right homonymous visual field defect remained. When a patient with tuberculous meningitis presents with abrupt onset oculomotor nerve palsy, rapid re-diagnosis should be undertaken and proper treatment initiated, because the prognosis is critically dependent on the timing of adequate treatment.

Blefaroptose em usuários de lentes de contato / Blepharoptosis in contact lens wearers

OBJETIVO: Investigar a freqüência de blefaroptose adquirida em usuários de lentes de contato. MÉTODOS: Avaliação prospectiva de 50 pacientes, usuários de lentes de contato, do Setor de Lentes de Contato do Serviço de Oftalmologia do Complexo Hospitalar Santa Casa de Porto Alegre, durante o período de abril a novembro de 2004. A distância reflexo-margem (MRD) foi avaliada em 99 pálpebras de usuários de lentes de contato e para as 52 pálpebras de controle. Pacientes cuja medida da distância reflexo-margem se apresentou inferior a 2 mm ou com assimetria de distância reflexo-margem maior ou igual a 2 mm foram considerados portadores de blefaroptose. Foram avaliados o tipo de lente de contato utilizada e o tempo de uso das mesmas. RESULTADOS: Cinco pacientes apresentaram ptose, todos eles eram usuários de lentes de contato rígidas, um com ptose bilateral e quatro, unilateral. A distância reflexo-margem dos pacientes usuários de lentes de contato foi, em média, 0,88 mm inferior aos não usuários. Os valores de distância reflexo-margem foram progressivamente decrescentes nos grupos estudados: controles, usuários de lentes gelatinosas e de lentes rígidas. CONCLUSÃO: O estudo sugere que os usuários de lentes de contato possuem alteração dos valores de distância reflexo-margem, principalmente os que usam lentes rígidas.

PURPOSE: To investigate the occurrence of acquired blepharoptosis in contact lens wearers. METHODS: Prospective analysis of 50 contact lens wearers being followed at the Contact Lenses Section of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre" between April and November 2004. The margin reflex distance (MRD) was evaluated for the 99 eyelids of contact lens wearers and for the 52 eyelids of controls. A patient whose measurement was less than 2 mm or with an assymetry of margin reflex distance greater or equal to 2 mm were considered with blepharoptosis. The contact lens type and duration of contact lenses wear were evaluated. RESULTS: Five patients presented ptosis, all of them were hard contact lens wearers, one had bilateral and four had unilateral ptosis. The study shows that the contact lens wearers had the margin reflex distance 0.88 mm smaller than the non-wearers. The margin reflex distance values decreased progressively in the studied groups: controls, gelatinous contact lens wearers and rigid contact lens wearers. CONCLUSION: The study suggests that contact lens wearers have alterations in the margin reflex distance values, especially the rigid contact lens wearers.

[Clinical outcomes of surgery for double elevator palsy]

To evaluate the clinical findings and surgical management of patients with congenital unilateral double elevator palsy [DEP] or monocular elevation deficiency [MED]. In a non-comparative interventional case series, 27 consecutive cases of DEP were studied. Hypotropia, elevation deficiency, and pseudoptosis were corrected by Knapp or Callahan procedure with or without inferior rectus recess. Ptosis was corrected by anterior levator resection [ALR] and brow suspension. Levator excision and brow suspension was performed for correction of accompanying jaw winking ptosis. Horizontal strabismus repair, belpharoplasty, and double Z- plasty for epicanthal folds were done in some cases. This series included 15 female and 12 male subjects with mean age of 13 +/- 10 years. All patients except two were sporadic cases. Definite congenital DEP was present in two members of a consanguineous family. In most cases, the presenting complaint was ipsilateral ptosis [74%]. Hypotropia with various degrees of severity was found in 20 cases [74%]. Six patients [22%] had jaw winking ptosis of the ipsilateral eye. Knapp procedure was performed in 6 and Callahan procedure was performed in 4 cases. True ptosis was corrected by anterior levator resection in 9 and brow suspension in 8 eyes. Levator excision and brow suspension was performed in 3 patients with accompanying jaw winking ptosis. In one case with mild jaw winking, levator resection was done. Hypotropia was corrected in 80% after surgery and eye elevation increased by 25 +/- 15 PD. Ptosis correction procedures successfully improved chin up position and cosmetic appearance in addition to opening the visual axis. Anterior segment ischemia was not found in any cases after one year of follow up. Blepharoptosis and hypotropia the chief clinical features and presenting complaints in this condition. Knapp and Callahan procedure with or without inferior rectus recess are effective and should be consider prior to considering surgical intervention for the ptosis

Fenômeno de Marcus Gunn: diagnóstico diferencial das ptoses palpebrais na criança / Marcus Gunn Phenomenon: differential diagnosis of palpebral ptoses in children

OBJETIVO: Este trabalho teve por objetivo fazer uma revisão bibliográfica, relatar e discutir o caso clínico de um paciente com fenômeno de Marcus Gunn. DESCRIÇAO: Criança de 5 anos de idade, sexo feminino, hígida. Nos primeiros meses de vida, em consulta de puericultura, foi detectada alteração no olho direito, que, a princípio, parecia tratar-se de estrabismo. Após consultas com vários oftalmologistas, não se alcançou um diagnóstico preciso. Já aos 4 anos de idade, após exame realizado por oftalmologista pediátrico, confirmou-se o diagnóstico do fenômeno de Marcus Gunn. O restante do exame físico, incluindo exame neurológico, estava normal. Por se tratar de ptose palpebral leve, sem outras patologias associadas, optou-se por uma conduta conservadora. COMENTARIOS: Este relato visa alertar os pediatras com relação ao fenômeno de Marcus Gunn, que ainda é pouco conhecido. A partir deste conhecimento, o pediatra poderá identificar o fenômeno, possibilitando o encaminhamento precoce para a abordagem de complicações ou condições associadas, além de diagnóstico diferencial com outros tipos de ptose palpebral.
