ABSTRACT

PURPOSE: Despite various existing surgical techniques, treatment of facial nerve palsy remains difficult. The purpose of this report is to present the cerclage sling technique using temporalis fascia to manage paralytic lagophthalmos. METHODS: A series of six patients underwent a cerclage sling technique using temporalis muscle fascia to treat paralytic lagophthalmos. The technique is presented in detail. Symptoms, palpebral fissures, and lagophthalmos were assessed pre- and postoperatively. Data were submitted for statistical analysis. RESULTS: After surgery, all patients achieved a reduction in clinical symptoms. The upper eyelids had lowered, and the inferior eyelids had elevated, reducing ocular exposure even if mild residual lagophthalmos was present. CONCLUSION: Cerclage using the temporalis muscle fascia sling technique is a safe and effective procedure to treat facial nerve paralytic lagophthalmos. A reduction in ocular exposure and lagophthalmos provides improvement in clinical symptoms and eyelid function.

ABSTRACT

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.

ABSTRACT

PURPOSE: To assess the sensitivity and specificity of lateral midpupil lid distances for the detection of upper lid lateral flare. METHODS: Lateral lid flare was determined by unanimous agreement among six experienced oculoplastic surgeons in the grading of photographs obtained for patients with Graves orbitopathy (GO). Bézier lines were employed to extract the upper eyelid contours of the patients and a control group of age and sex matched subjects. Custom software was employed to determine 5 lateral midpupil eyelid distances. The sensitivity and specificity of each measurement in detecting lateral flare were estimated from receiver operating characteristic curves. The non-parametric Kruskal-Wallis one-way analysis of variance (ANOVA) with Dunn's posthoc test was used to compare the median values of the contour parameters between groups. RESULTS: The degree of agreement between judges evaluated with the Fleiss' Kappa test was relatively high (K = 0.69, z = 16.6, p < .0001). The raters classified 12 lids with lateral lid flare (LLF) and 7 without LLF in patients with GO. There was no agreement on the presence or absence of LLF in 11 lids. In all eyes, lateral midpupil lid distances diminished from the center of the eyelid towards the lateral canthus. Receiver operating characteristic analysis for the midpupil distances revealed that the fourth distance from the center demonstrated high sensitivity and specificity in detecting flare. At this location (2.5 mm medial to the lateral canthus) a midpupil distance equal to or greater than 60% of the margin reflex distance (MRD1) indicated the presence of flare. CONCLUSIONS: - A single measurement of a lateral midpupil eyelid distance 2.5 mm medial to the lateral canthus is a sensitive and specific measurement for the diagnosis of the LLF.

ABSTRACT

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.

ABSTRACT

We report an unusual case of a 53-year-old male with fistula, ectropion and lagophthalmos due to lateral frontal rhinosinusitis. Two years ago, he presented soft erythematous swelling at internal epicanthus. A year and a half before, he presented upper eyelid fistula secretion drainage, cicatricial ectropion and lagophthalmos. No otorhinolaryngological or visual discomfort was reported. Ophthalmology performed ectropion surgical repair using skin grafting, with no improvement. They requested magnetic resonance imaging which showed a suggestive image of frontal lateral sinusitis, being transferred to the Otorhinolaryngology service. External and endoscopic nasal surgery was performed, which resolved the sinus pathology with good evolution.


Se informa un inusual caso de un varón de 53 años, con fístula, ectropión y lagoftalmos derecho debido a rinosinusitis crónica frontal lateral. Dos años antes presentó tumefacción blanda y eritematosa en el epicanto interno. Un año y medio antes tuvo drenaje de secreción por fístula en el párpado superior, ectropión cicatrizal superomedial y lagoftamos ipsilateral, sin molestias otorrinolaringológicas ni alteración visual. El Servicio de Oftalmología realizó reparación quirúrgica mediante injerto de piel, sin mostrar mejoría, por lo que se solicitó resonancia magnética, que evidenció imagen indicativa de sinusitis frontal lateral derecha y fue transferido al Servicio de Otorrinolaringología. Se practicó una cirugía externa y endoscópica, que resolvió la afección sinusal, con buena evolución.

ABSTRACT

Resumo A doença relacionada ao IgG4 é uma condição imunomediada caracterizada pela presença de lesões com reação inflamatória associada à fibrose e à infiltração linfoplasmocitária rica em plasmócitos tissulares IgG4 positivos, compondo um espectro de doenças fibroproliferativas. A patogênese da DRIgG4 ainda é pouco compreendida e o tratamento é empírico. Relatamos o caso de um homem de 50 anos com lesões amareladas palpebrais associadas a edema local, diagnosticadas previamente como processo alérgico, até que biópsia com estudo imuno-histoquímico e dosagem de IgG4 sérico aventaram a hipótese de doença relacionada ao IgG4. Foi iniciado tratamento com corticoide e rituximabe, observando-se estabilização do quadro e sem apresentação de outras formas clínicas da doença.


Abstract IgG4-Related Disease is an immunomediated condition that is characterized by the presence of inflammatory lesions associated with fibrosis and lymphoplasmacytic infiltration rich in positive IgG4 tissue plasmocytes, forming a spectrum of fibroproliferative diseases. The pathogenesis of IgG4-RD is still poorly understood and the treatment is empirical. We report the case of a 50-year-old man with yellow eyelid lesions associated with local edema, previously diagnosed as an allergic process, until biopsy with immunohistochemical study and serum IgG4 dosage revealed the hypothesis of IgG4 related disease. Treatment with corticoid and rituximab was initiated, showing stabilization of the condition, without presenting other clinical forms of the disease.

ABSTRACT

A 37-year-old female presented with severe apraxia of lid opening (ALO) affecting the right upper lid associated with Becker congenital myotonia (MC). The patient had a history of right upper lid ptosis for 25 years that was exacerbated over the previous month with severe incapacity to open her right eye. No other associated neurological or ophthalmic symptoms were observed. The patient was treated with botulinum toxin (BoNT-A) injection into the pretarsal and lateral canthus region of the orbicularis oculi of the affected eyelid. Treatment with BoNT-A is an effective method of managing ALO in Becker MC. This is the first case of unilateral ALO in the course of Becker MC that was successfully treated with injections of botulinum toxin.

ABSTRACT

Eyelid retraction, has received limited attention and it has passively been interpreted as the result of an overactive levator palpebrae superioris muscle secondary to midbrain injury. However, eyelid retractions can occur in other neurological diseases, not directly related with the midbrain. We report three patients who developed eyelid retraction. One patient had a bilateral eyelid retraction, related with Creutzfeldt-Jakob disease (CJD). Another patient had a unilateral right eyelid retraction associated with a thalamic-mesencephalic infarct. The third patient had a bilateral pontine infarction on magnetic resonance imaging. In the patient with CJD, eyelid retraction did not subside. Among patients with infarctions, the retraction persisted after focal symptoms had subsided, showing an evolution that was apparently independent of the basic process. The analysis of these patients allows us to conclude that the pathogenesis of eyelid retraction includes supranuclear mechanisms in both the development and maintenance of the phenomenon. Unilateral or bilateral eyelid retraction does not alter the normal function of eyelid, which ever had normal close eye blink. In these reported cases, a hyperactivity of levator palpebrae superioris muscle was clinically ruled out.

ABSTRACT

BACKGROUND: Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. OBJECTIVE: To evaluate thelipid profile and important clinical aspects of xanthelasma palpebrum patients. METHODS: In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and 42 cases of non-inflammatory skin disorders as thecontrol group, matched for age and gender.The clinical characteristics of the patients and fasting serum lipid profile were recorded for both groups. The data obtained were analyzed using SPSS-16. RESULTS: Xanthelasma palpebrum was found more commonly in middle-aged females with disease onset of less than 1 year, and without significant familial history of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the upper lid with mild extension and was rarely associated with systemic disease. There was no statistically significant difference between two groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia (p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl), triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl) were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was lower in thepatient group. CONCLUSION: In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a significant difference between thepatient and control groups; however, mean serum values for cholesterol, triglyceride, VLDL and HDL showed a significant difference between the two groups. Therefore, in addition to lipid abnormality, other factors could be involved in the pathogenesis of xanthelasma palpebrum.

ABSTRACT

OBJECTIVE: To describe the epidemiology, etiology, pathogenesis, clinical characteristics, and management of pemphigus, with an emphasis on ocular involvement. METHODS: Literature review. RESULTS: Pemphigus is an autoimmune epithelial blistering disease of the skin and mucous membranes. The typical pathological finding is acantholysis of the epidermis that leads to blister formation. Immunofluorescence techniques show autoantibody deposition on the epidermal intercellular substance. Although a genetic background is necessary, environmental factors are crucial for the onset and perpetuation of the disease. Exposure to some drugs, toxic agents, and foods and associations with other autoimmune diseases and lymphoproliferative conditions should be assessed. Generally, the skin is the most commonly affected tissue. Ocular involvement might be present and exhibit a clinical course that is independent of skin compromise. Visual function may be affected depending on the severity of the presentation. In untreated cases, mortality is high because of bacterial sepsis and hydroelectrolyte imbalance. A multidisciplinary approach should be used involving a dermatologist, ophthalmologist, and immunologist. Immunosuppressive agents are the mainstay of treatment; corticosteroids typically with azathioprine or mycophenolate mofetil are the drugs of choice. Surgical treatment of trichiasis and malposition of the eyelids and tectonic procedures for corneal perforation are sometimes required in very severe and recalcitrant cases. CONCLUSIONS: Pemphigus is a potential life- and sight-threatening disease. Understanding the disease facilitates the adequate assessment of the modifiable factors and the prompt initiation of immunotherapy. Ocular involvement can develop in patients with pemphigus. Adequate ophthalmological care is needed, in particular, prevention of infections, scarring, and corneal perforation.

ABSTRACT

In Chile, loxoscelism is caused by the bite of the Loxosceles laeta spider. The clinical presentation has two different forms: cutaneous loxoscelism (CL) and vicero-cutaneous loxoscelism, which is less frequent. Cutaneous loxoscelism includes an uncommon clinical variation (4%), called CL with edematous predominance (CLEP). We present a 5-year-old patient with sudden pain and edema on his right eyelid associated with fever, which progressed rapidly involving the right hemifacial area, frontal region, and left eyelid. Angioedema and pre-orbital cellulitis were discarded and CLEP was suspect. Cutaneous loxoscelism with an edematous predominance is self-limited, benign and with little or no necrotic injury due to the edema, which dilutes the toxin-induced enzymatic process causing necrosis. As in the reported cases it usually responds well to medical treatment and does not cause visceral involvement.

El loxoscelismo en Chile es un cuadro producido por la mordedura de la araña Loxosceles laeta. Las formas de presentación son: loxoscelismo cutáneo (LC) y loxoscelismo cutáneo-visceral (LCV), el último menos frecuente. Dentro del LC existe una variante poco común (4%) conocida como loxoscelismo cutáneo predominantemente edematoso (LCPE). Nuestro caso es un paciente de 5 años que consultó por cuadro de inicio súbito de dolor y edema palpebral derecho, asociado a fiebre el cual evolucionó con rápida progresión extendiéndose en la hemicara derecha, región frontal y párpado izquierdo. Se descartó un angioedema y una celulitis periorbitaria, sospechándose un LCPE. Se manejó con hidrocortisona y clorfenamina. El LCPE es un cuadro benigno, autolimitado, en que no está presente la lesión necrótica o ésta es insignificante. Predomina el edema, el cual abortaría la necrosis al diluir el proceso enzimático producido por el veneno. Tiene buena respuesta al tratamiento médico, con ausencia de compromiso visceral.
