Evaluation of Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum

ABSTRACT Purpose: To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. Methods: This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. Results: A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. Conclusion: In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

Upper and lower blepharoplasty technique associated with canthopexy with double pre septal orbicularis muscle elevation with a single suture / Blefaroplastia superior e inferior associada à cantopexia com elevação dupla de músculo orbicular pré-septal em sutura única

ABSTRACT Objective: To describe the upper and lower blepharoplasty technique associated with canthopexy with double pre septal orbicularis muscle elevation with a single suture in order to evaluate the efficacy of the technique. Methods: This is a retrospective study in which the medical records of 5,882 patients who underwent this technique between January 1999 and July 2015 were evaluated. The frequency and main causes of clinical complications and surgical reoperation were analyzed. Results: The incidence of complications found was 12.7% (n=750), being 0.8% (n=47) due to persistent chemosis, 3% (n=176) due to poor lower eyelid positioning, 4.17% (n=245) due to mild eyelid retraction and 4.8% (n=282) because of mild to moderate chemosis. Conclusion: The technique appears to be effective as it is simple and practical, and capable of resulting in positive functional and aesthetic outcomes with low rates of complications.

Reconstrução após ressecção bipalpebral com preservação do globo ocular: desafio estético e funcional / Reconstruction after bipalpebral resection with preservation of the eyeball: aesthetic and functional challenge

Introdução: A reconstrução palpebral pode ser realizada por fechamento primário, enxerto de diferentes lamelas e retalhos locais e/ou regionais, únicos ou combinados. Essa reconstrução se torna mais complexa quando a pálpebra superior e a inferior são ressecadas em espessura total e o globo ocular é preservado. O objetivo é relatar as técnicas utilizadas para reconstrução periorbital em casos de ressecção bipalpebral (superior e inferior) com preservação do globo ocular pelo Grupo de Cirurgia Órbitopalpebral da Divisão de Cirurgia Plástica e Queimaduras do HCFMUSP. Métodos: Foram revistos todos os casos que se encaixaram nos critérios de inclusão no período de 2000 a 2019, sendo descritos dados epidemiológicos, cirúrgicos e de seguimento pós-operatório. Resultados: Apenas dois casos foram submetidos à exérese total do tecido periorbital e permaneceram passíveis de preservação do globo ocular. Ambos foram reconstruídos com retalhos frontais com oclusão total do globo ocular no primeiro momento, seguido pela liberação em etapas, mantendo o globo viável após a finalização da reconstrução. Discussão: São escassos os relatos semelhantes na literatura e, nestes casos, os resultados cirúrgicos se mostraram funcionalmente aceitáveis, mas com limitações estéticas importantes. Conclusão: Sugerimos uma nova opção para a reconstrução total da pálpebra superior e inferior (com um único retalho pedicular, desprovido de enxerto conjuntivo e em múltiplos estágios) que fornece proteção e conservação do globo ocular durante as diferentes etapas da cirurgia. Os resultados foram funcionalmente favoráveis, considerando a gravidade dos casos.

Introduction: Eyelid reconstruction can be performed by primary closure, a graft of different lamellae, and local and/or regional flaps, single or combined. This reconstruction becomes more complex when the upper and lower eyelids are resected to total thickness, and the eyeball is preserved. The objective is to report the techniques used for periorbital reconstruction in bipalpebral resection cases (upper and lower) with preservation of the eyeball by the Group of Orthopalpebral Surgery of the Division of Plastic Surgery and Burns of HCFMUSP. Methods: All cases that met the inclusion criteria from 2000 to 2019 were reviewed, and epidemiological, surgical, and postoperative follow-up data were described. Results: Only two cases were submitted to total exeresis of the periorbital tissue and remained susceptible to eyeball preservation. Both were reconstructed with frontal flaps with complete occlusion of the eyeball at the first moment, followed by the release in stages, keeping the globe viable after reconstruction completion. Discussion: Similar reports are scarce in the literature, and, in these cases, surgical results were functionally acceptable but with significant aesthetic limitations. Conclusion: We suggest a new option for total reconstruction of the upper and lower eyelid (with a single pedicular flap, devoid of connective graft and in multiple stages) that protects and conserves the eyeball during the various stages of surgery. The results were functionally favorable, considering the severity of the cases.

Festoons, edema e bolsas malares: existe consenso no tratamento estético? / Festoons, edema, and malar bags: is there a consensus on aesthetic treatment?

Introdução: As alterações periorbitais são alguns dos primeiros sinais detectáveis do envelhecimento. O destaque, atualmente, refere-se ao rejuvenescimento dessa região, envolvendo o tratamento desde as sobrancelhas até a transição órbito-malar, onde se encontram festoons, edemas e bolsas malares. Entretanto, este manejo é complexo, envolvendo várias abordagens: técnicas invasivas ou não invasivas. Assim, esta revisão objetiva descrever as evidências científicas relacionadas às técnicas mais atuais utilizadas no tratamento de festoons, edemas e bolsas malares e avaliar as complicações relacionadas à cada modalidade. Métodos: A pesquisa foi realizada em três bases de dados - PubMed, Cochrane e LILACS - utilizando os descritores "bolsa malar", "malar mounds", "festoons" e "malar bags" no período de 2014 a 2019, na língua inglesa e portuguesa. Resultados: Foram selecionados 13 artigos, a maioria dos estudos eram revisões retrospectivas (76,9%), sete versavam sobre técnicas não invasivas, 3 sobre invasivas e 3 sobre associação das técnicas. Em relação aos procedimentos descritos, os não invasivos foram representados pelo uso de Kinesio tape, injeção de tetraciclina, doxiciclina e de ácido hialurônico, e o uso de microagulhamento com radiofrequência. Já os invasivos foram representados por microaspiração, retalho miocutâneo, lift subperiosteal da face média e excisão direta. Conclusão: Existem inúmeras técnicas para tratamento de festoon e bolsas malares, mas cabe ao cirurgião plástico conhecer suas vantagens e desvantagens para decidir a mais adequada em cada situação. Assim, não há consenso, mas é vital diagnosticar corretamente para indicar o melhor tratamento.

Introduction: Periorbital changes are some of the first detectable signs of aging. The most outstanding currently, refers to the rejuvenation of this region, involving the treatment from the eyebrows to the transition orbital-malar, where are festoons, edemas, and malar bags. However, this management is complex, involving several approaches: invasive or noninvasive techniques. Thus, this review aims to describe the scientific evidence of the most current techniques used in the treatment of festoons, edema, and malar bags and to evaluate the complications related to each modality. Methods: The research was carried out in three databases, PubMed, Cochrane, and LILACS - using the descriptors "bolsa malar," "malar mounds," "festoons" and "malar bags" in the period from 2014 to 2019, in English and Portuguese. Results: We selected 13 articles; most of the studies were retrospective reviews (76.9%), seven dealt with noninvasive techniques, three about invasive, and three on the association of techniques. Regarding the procedures described, the noninvasive ones were represented by the use of Kinesio tape, tetracycline injection, doxycycline and hyaluronic acid, and the use of microneedling with radiofrequency. The invasive ones were represented by microaspiration, myocutaneous flap, subperiosteal lift of the middle face, and direct excision. Conclusion: There are numerous techniques for treating festoon and malar bags, but it is up to the plastic surgeon to know its advantages and disadvantages to decide the most appropriate in each situation. Thus, there is no consensus, but it is vital to diagnose correctly to indicate the best treatment.

Intra- and interobserver reliability of a modified distraction test based on digital images to assess lower eyelid horizontal tension / Confiabilidade intra e interobservador do teste de tração modificado para avaliar a tensão da pálpebra inferior baseado em imagens digitais

ABSTRACT Purpose: Inferior eyelid laxity is classically evaluated using "snap-back" and "distraction" tests. This study aimed to assess the reproducibility of the technique used to indirectly quantify the horizontal tension in the lower eyelids using digital image processing. Methods: This longitudinal study was conducted to assess the reproducibility of a new technique that quantifies the horizontal tension in the lower eyelid. The study was conducted at the Hospital das Clínicas of Porto Alegre. The protocol was established by two trained ophthalmologist examiners, allowing intra- and interobserver agreement analyses. Image acquisition was done in two stages: the first image was captured with the eyelid in primary gaze position and the second with the eyelid in traction position. All images and measurements were processed using Image J 1.33m software from the National Institute of Health. The Bland-Altman method, intraclass correlation coefficients, concordance correlation coefficients, and technical measurement error were used to evaluate reproducibility. Results: The study participants comprised healthy individuals with no ophthalmologic pathologies. The measurements obtained in the neutral position showed a slightly higher agreement than those obtained in the traction position. The mean difference between the measurements performed in the traction position was 0.028 ± 0.7 mm and 0.014 ± 0.9 mm in the intra- and interobserver analyses, respectively. The Bland-Altman method demonstrated adequate confidence limits for both measurements. Correlation coefficients for measurements varied between 0.87 [95% confidence interval (CI) 0.68-0.95] and 0.91 (95% CI 0.77-0.97) in the neutral position and between 0.72 (95% CI 0.37-0.89) and 0.76 (95% CI 0.4-0.91) in the traction position. Conclusion: A high intra- and interobserver concordance was observed in the studied method to quantify lower eyelid tension. The proposed method is simple and easily reproducible, and to the best our knowledge, this is the first method that quantifies lower eyelid horizontal tension on the basis of digital image processing. This modified distraction test might be useful in studies quantifying lower eyelid horizontal tension.

RESUMO Objetivo: A frouxidão palpebral inferior é avaliada classicamente por meio de testes de "snap-back" e "distraction test". O objetivo deste estudo foi avaliar a reprodutibilidade da técnica utilizada para quantificar indiretamente a tensão horizontal nas pálpebras inferiores através do processamento digital de imagens. Métodos: Este estudo longitudinal foi realizado para avaliar a reprodutibilidade de uma nova técnica que quantifica a tensão horizontal na pálpebra inferior. O estudo foi realizado no Hospital das Clínicas de Porto Alegre. O protocolo foi estabelecido por dois examinadores oftalmologistas treinados, permitindo análises de concordância intra e interavaliador. A aquisição de imagens foi feita em duas etapas: a primeira imagem foi capturada com a pálpebra na posição primária do olhar e a segunda com pálpebra tracionada. Todas as imagens e medições foram processadas usando o software Image J 1.33m do National Institute of Health. O método de Bland-Altman, os coeficientes de correlação intraclasses, os coeficientes de correlação de concordância e o erro técnico da medida foram utilizados para avaliar a reprodutibilidade. Resultados: Os participantes do estudo foram indivíduos saudáveis e sem patologias oftalmológicas. As medidas obtidas na posição neutra mostraram concordância levemente maior do que as obtidas na posição tracionada. A diferença média entre as medidas realizadas na posição tracionada foi de 0,028 ± 0,7mm e 0,014 ± 0,9mm nas análises intra e interobservadores, respectivamente. O método de Bland-Altman demonstrou limites de confiança adequados para ambas as medidas. Os coeficientes de correlação para as medidas variaram entre 0,87 [intervalo de confiança de 95% (IC) 0,68-0,95) e 0,91 (IC 95% 0,77-0,97) na posição neutra e entre 0,72 (IC 95% 0,37-0,89) e 0,76 (IC 95% 0,46-0,91) na posição tracionada. Conclusão: Observou-se elevada concordância intra e interobservador no método estudado para quantificar a tensão palpebral inferior. O método proposto é simples e facilmente reproduzível, e, do melhor modo possível, este é o primeiro método que quantifica a tensão horizontal da pálpebra inferior com base no processamento digital de imagens. Este teste de distração modificado pode ser útil em estudos que quantifiquem a tensão horizontal da pálpebra inferior.

Retalho zigomático-palpebral: uma técnica opcional para a reconstrução da pálpebra inferior / Zygomatic-palpebral flap: an optional technique for lower eyelid reconstruction

Introdução: A reconstrução de pálpebra inferior representa um desafio peculiar ao cirurgião plástico, uma vez que traduz uma região facial de importância estética e funcional. O objetivo é apresentar uma técnica opcional para a reconstrução de defeitos da pálpebra inferior com o retalho cutâneo zigomáticopalpebral. Esta técnica mostra uma alternativa nos casos de pele escleroatrófica de pessoas idosas, bem como para pessoas jovens, que não apresentam redundância da pele palpebral superior, impossibilitando por exemplo o uso de enxertos de pálpebra superior ou retalhos como o de Fricke ou Tripier. Métodos: Os autores mostram a indicação do retalho em casos de ectrópio cicatricial, reconstrução após ressecção de neoplasias, associação com outros retalhos como de Hughes ou para cobertura de enxertos cartilaginosos. É um retalho de transposição composto por pele e subcutâneo, randomizado. A técnica baseia-se no uso de retalho local, de características muito semelhantes à área do defeito, o que permite mimetização, segurança e exequibilidade. Resultados: Os resultados imediatos e tardios são satisfatórios e bem aceitos pelos pacientes e pela equipe cirúrgica em termos estéticos e funcionais, com oclusão palpebral adequada e lubrificação ocular preservada. Conclusão: O retalho zigomático-palpebral apresenta como vantagens a simplicidade de execução, sangramento mínimo, baixa morbidade de área doadora e feito sob anestesia local. O objetivo de reconstruir defeitos da pálpebra é restaurar a anatomia e função. Esta pode ser uma tarefa desafiadora, especialmente em defeitos maiores que podem estar presentes nos procedimentos oncológicos em jovens e em idosos com pele escleroatrófica e mínima frouxidão.

Introduction: Lower eyelid reconstruction represents a unique challenge to plastic surgeons, since it involves a facial region of aesthetic and functional importance. The objective is to present an optional technique for the reconstruction of lower eyelid defects using zygomatic-palpebral skin flap. This technique represents an alternative in cases of scleroatrophic skin in older patients, and for young people who do not have an upper eyelid skin redundancy, which prevents, for example, the use of upper eyelid grafts or flaps such as those of Fricke or Tripier. Methods: The authors describe the flap used in cases of cicatricial ectropion and reconstruction after resection of neoplasms and association with other flaps, such as those of Hughes, or for coverage of cartilage grafts. The flap consisted of a transposition flap made up of skin and underlying subcutaneous tissues, randomized . The technique was based on the use of a local flap with highly similar characteristics to the defect area, which allowed it to mimic functions, while being safe and feasible. Results: The immediate and late results in terms of aesthetics and function were satisfactory and well accepted by patients and the surgical team, with adequate eyelid occlusion and preserved ocular lubrication. Conclusion: The advantages of the zygomatic-palpebral flap are its ease of execution, minimal bleeding, low morbidity of the donor area, and the use of local anesthesia. The reconstruction of eyelid defects aims to restore anatomy and function. This can be a challenging task, especially in cases with larger defects that may be present after oncologic procedures both in young and old patients presenting with scleroatrophic skin and minimal tissue laxity.

Tratamento cirúrgico da ptose palpebral moderada e grave: análise de resultados / Surgical treatment of moderate and severe ptosis: analysis of results

Introdução: A ptose palpebral é uma afecção comum na prática clínica na qual uma perfeita avaliação torna-se mandatória. Definimos ptose quando a margem palpebral encontra-se abaixo de 2 mm da junção córneo escleral e pode ser classificada em leve, moderada e grave. Existem inúmeras técnicas de reparo e a escolha dependerá da classificação da função do músculo levantador. Métodos: Foram analisados de forma prospectiva, no período de março de 2013 a maio de 2015, quatorze (n = 14) pacientes submetidos ao tratamento cirúrgico de ptose palpebral moderada e grave (n = 21). Inúmeros fatores foram estudados, tais como grau de ptose e função do músculo elevador da pálpebra, tipo de técnica de reparo, complicações imediatas e tardias, etc. Resultados: Quatorze pacientes foram opera-dos, totalizando 21 pálpebras, sendo que, 85% foram de etiologia adquirida e 15% congênita. Com relação ao grau de ptose, 64,3% (n = 9) foram moderadas e 35,7% (n = 5) graves. No que tange à função do músculo levantador, encontramos função boa 28,5% (n = 4), moderada 28,5% (n = 4) e pobre 43% (n = 6). Em relação às com-plicações, 2 casos de hiperemia conjutival e um caso de edema. Obtivemos um alto índice de satisfação com 85,7% (n = 12), com baixas taxas de complicações. Conclusão: A ptose palpebral é uma enfermidade comum na prática clínica e exige por parte do cirurgião um perfeito conhecimento anatômico da delicada estrutura palpebral e também de sua fisiopatologia. Uma perfeita avaliação desse paciente torna-se mandatória para o emprego do tratamento mais adequado.

Introduction: Eyelid ptosis is a common condition in clinical practice for which a complete evaluation is mandatory. Ptosis is defined when the eyelid margin is 2 mm below the corneoscleral junction and can be classified as mild, moderate, and severe. There are numerous repair techniques, and the choice will depend on the classification of the function of the levator muscle. Methods: We evaluated prospectively, from March 2013 to May 2015, 14 patients who underwent surgical treatment of moderate and severe ptosis (n = 21). Several factors were studied, such as degree of ptosis and function of the eyelid levator muscle, type of repair technique, and immediate and late complications. Results: Fourteen patients (21 eyelids) underwent operation. The etiology was acquired in 85% of the cases and congenital in 15%. With respect to the degree of ptosis, 64.3% (n = 9) of the cases were moderate and 35.7% (n = 5) were severe. With respect to the muscle function of the levator, good, moderate, and poor functions were observed in 28.5% (n = 4), 28.5% (n = 4), and 43% (n = 6) of the cases, respectively. With regard to complications, 2 cases of conjunctival hyperemia and one case of edema were observed. We obtained a high satisfaction rate of 85.7% (n = 12), with low complication rates. Conclusion: Eyelid ptosis is a common presentation in clinical practice and requires on the part of the surgeon a detailed anatomical knowledge of the delicate structure of the eyelid and its pathophysiology. A complete evaluation of these patients is mandatory for the employment of the most appropriate treatment.

Upper eyelid platinum weight placement for the treatment of paralytic lagophthalmos: A new plane between the inner septum and the levator aponeurosis

BACKGROUND: The most common surgical treatment for paralytic lagophthalmos is the placement of a weight implant in the upper eyelid; however, this technique confers the risks of implant visibility, implant extrusion, and entropion. In this study, we present a new technique of placing platinum weight implants between the levator aponeurosis and inner septum to decrease such complications. METHODS: A total of 37 patients with paralytic lagophthalmos were treated between March 2014 and January 2017 with platinum weight placement (mean follow-up, 520.1 days). After dissecting through the orbicularis oculi muscle, the tarsal plate and levator aponeurosis were exposed. The platinum weights (1.0–1.4 g) were fixed to the upper margin of the tarsal plate and placed underneath the orbital septum. RESULTS: Five patients could partially close their eye after surgery. The average distance between the upper eyelid and the lower eyelid when the eyes were closed was 1.12 mm. The rest of the patients were able to close their eye completely. Three patients patient developed allergic conjunctivitis after platinum weight insertion, which was managed with medication. None of the patients complained of discomfort in the upper eyelid after surgery. Visibility or extrusion of the implant were observed in three patients. CONCLUSIONS: Postseptal weight placement is a safe and reproducible method in both primary and secondary upper eyelid surgery for patients with paralytic lagophthalmos. It is a feasible method for preventing implant visibility, implant exposure, and entropion. Moreover, platinum is a better implant material than gold because of its smaller size and greater thinness.

Tratamento cirúrgico do entrópio palpebral inferior involucional / Surgical treatment of involutional lower lid entropy

Introdução: O entrópio é definido como uma rotação interna da margem palpebral. O contato dos cílios e da pele palpebral com o globo ocular pode resultar em sintomas irritativos, abrasões e cicatrizes corneanas. Este trabalho tem o objetivo de apresentar a eficácia da técnica descrita por Lessa no tratamento do entrópio involucional. Métodos: Foram submetidos à correção do entrópio involucional 13 pálpebras inferiores de 11 pacientes. Utilizou-se a técnica de Lessa, em que é realizada uma incisão subciliar, descolamento subcutâneo, ressecção de faixa muscular e sutura pele-septo-pele, associada a um procedimento de suporte lateral. Resultados: Foram operados 11 pacientes (5 homens e 6 mulheres), com média de idade de 76,72 anos, (69 até 84 anos), totalizando 13 pálpebras, pois dois pacientes apresentavam a afecção bilateralmente. Em oito pacientes (9 pálpebras) usou-se a suspensão muscular. Em um paciente, a suspensão tarsal, e em dois (três pálpebras) o retalho tarsal. O tempo cirúrgico médio (por pálpebra) dos pacientes submetidos à suspensão muscular foi de 36,55 minutos, enquanto nos submetidos à cantoplastia foi de 56 minutos. Nenhum paciente apresentou recidiva e um paciente apresentou ectrópio. Conclusão: A técnica descrita por Lessa mostrou-se eficaz, pois não houve nenhum caso de recidiva.

Introduction: Entropion is defined as an internal rotation of the eyelid margin. The contact of the eyelid skin and eyelashes with the eye may result in irritating symptoms, corneal abrasions, and scars. The purpose of this study is to present the effectiveness of the technique described by Lessa in the treatment of involutional entropion. Methods: We underwent correction of involutional entropion on 13 lower eyelids. We used the Lessa technique, in which a subciliary incision was made, a skin flap was dissected from the orbicularis oculi, a muscle strip was resected, and a skinseptum- skin suture was made. The procedure was associated with lateral support. Results: There were 11 patients (5 men and 6 women) with a mean age of 76.72 years (69 to 84 years), totaling 13 eyelids, as two patients had bilateral pathology. Eight patients (9 eyelids) used muscular suspension technique. In one patient, the tarsal suspension was performed, and in two patients (three eyelids), we used the tarsal flap. The mean operative time (for eyelid) of patients undergoing muscle suspension was 36.55 min, while that in patient undergoing canthoplasty was 56 min. No patient had recurrence, and one patient developed ectropion. Conclusion: The technique described by Lessa proved to be effective since there was no recurrence.

Retracción palpebral de causa neurológica: presentación de tres pacientes, interpretación patogénica / Eyelid retraction of neurologic origin: report of three cases

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.

Analysis of meibomain gland change and ocular surface condition in age-related cataract population / 中华实验眼科杂志

Background Meibomain gland is a specially differentiated sebaceous gland lying in the tarsus of upper and lower eyelid.The morphological changes of the gland is associated with a variety of ocular surface diseases.Studying the relationship of morphological and functional change of meibomain gland with ocular surface is of great significance.Objective This study was to observe the change of morphology,structure and function of meibomain gland over aging and investigate the assocation of meibomain gland abnormality with ocular surface.Methods A prospectively cases-observational study was performed.Ninety-three eyes of 93 patients with age-related cataract aged 45 and older were enrolled in Shanxi Eye Hospital from March to September 2016 under the informed consent.The patients were divided into 45 to 59-year group and ≥60-year group according to age or meibomian gland loss ≥ 1/3 group and meibomian gland loss ＜ 1/3 group.The ocular anterior segment,lid margin,meibomian gland orifices and lipids traits were examined by slit-lamp microscope.The ocular surface symptoms were assessed and scored by Ocular Surface Disease Index (OSDI) scale.The break-up time of tear film (BUT),tear meniscus height,meibomian gland dropout degree,conjunctival hyperemia and corneal fluorescence staining scores were measured using ocular surface analyzer.Results No dry eye symptom was complained in all the subjects,and their OSDI scores were ＜12.No abnormal changes at the lid margin and the muco-cutaneous junction were observed.No abnormality of the meibomian gland orifices,the lipids traits and drainage was observed under the slit-lamp microscope.BUT was shortened in 42 eyes (45.16％);tear meniscus height was lowed in 52 eyes (55.91％);meibomian gland loss range was ≥1/3 in 58 eyes (62.27％).The meibomian gland loss scores were 1.65±0.79 in the 45 to 59-year group and 1.86±0.72 in the ≥60-year group,showing an insignificant difference between them (t =1.301,P =0.197).But when coming to the correlation analysis,a positive correlation was found between meibomian gland loss scores and age (rs =0.323,P=0.002),and no correlations were seen between age and BUT or tear meniscus height (rs =0.154,P =0.141;rs=-0.024,P =0.821).In addition,meibomian gland loss scores showed a negative correlation with mean BUT (rs =-0.251,P =0.015).The eye number of BUT abnormality in the meibomian gland loss ≥ 1/3 group was more than that in meibomian gland loss ＜1/3 group (P =0.018).Conclusions Meibomian gland loss is more serious over aging in middle aged and elderly population,and serious meibomian gland loss increases the risk of tear film instability.The early meibomain gland dysfunction-like signs occur prior to symptoms,which should raise concern in clinical work.

Diseases treated in oculoplasty

Most people think that ophthalmology only treat diseases of the eyeball, but there are also many diseases of the accessory organs around the eyeball. Oculoplasty is a field of ophthalmology that deals with diseases of the eyelids, lacrimal system, and orbit. These accessory organs play important roles in protecting the eyes and supporting their function. Sometimes, diseases of these organs cause cosmetic problems, as well as functional problems. In the past, this field was considered rather indifferently and was not well recognized, so the treatment of these diseases was not specialized. However, concomitantly with recent improvements in quality of life and the increased desire of patients for these diseases to be treated, the importance of this field is increasing and many oculoplastic specialists are being trained. In the oculoplastic field, wide range of diseases are treated. In this report, the author provides a brief overview of the most important and common oculoplastic diseases.

Eyelid aging: pathophysiology and clinical management / Envelhecimento palpebral: fisiopatologia e considerações clínicas

ABSTRACTLife expectancy is increasing in most countries. With increasing age, many individuals may develop involutional ophthalmic diseases, such as eyelid aging. Dermatochalasis, ptosis, ectropion, and entropion are common disorders in middle-aged and older adults. This review outlines the pathophysiology and clinical management of these involutional eyelid disorders. Recently, a decrease in elastic fibers with ultrastructural abnormalities and an overexpression of elastin-degrading enzymes have been demonstrated in involutional ectropion and entropion. This may be the consequence of local ischemia, inflammation, and/or chronic mechanical stress. Eyelid aging with progressive loss of tone and laxity may affect the ocular surface and adnexal tissues, resulting in different clinical symptoms and signs. Surgical management depends on the appropriate correction of the underlying anatomical defect.

RESUMOA expectativa de vida está aumentando na maioria dos países. Com o envelhecimento, muitos indivíduos desenvolverão doenças oculares crônicas e involucionais, tais como o envelhecimento palpebral. Dermatocálase, ptose, ectrópio e entrópio são doenças frequentes em adultos e idosos. Esta revisão destaca a fisiopatologia e a clínica de doenças palpebrais involucionais. Recentemente, uma diminuição de fibras elásticas com anormalidades ultraestruturais e um aumento de enzimas degradantes de elastina foram demonstrados em ectrópio e entrópio involucionais. Isto pode ser consequência de isquemia local, inflamação e/ou estresse mecânico crônico. O envelhecimento palpebral com perda progressiva de tônus e flacidez pode afetar a superfície ocular e os anexos oculares, resultando em sinais e sintomas clínicos diferentes. O tratamento cirúrgico depende da correção apropriada do defeito anatômico subjacente.

Alterações palpebrais: frequência de ocorrência e perfil dos portadores em amostra populacional brasileira / Eyelid disorders: frequency of occurrence and profile of carriers in a Brazilian population sample

Objetivo: Apresentar a frequência de ocorrência das alterações palpebrais em uma amostra populacional brasileira, assim como as características de seus portadores. Métodos: Estudo transversal utilizando amostra populacional aleatorizada, realizado nos anos de 2004/2005, em nove cidades da região centro-oeste do estado de São Paulo. Foram examinadas 7654 pessoas sendo os participantes avaliados segundo variáveis demográficas e exame oftalmológico completo. As alterações palpebrais foram avaliadas por meio de exame externo usando lanterna e lâmpada de fenda. Os dados obtidos foram analisados estatisticamente. Resultados: As alterações palpebrais como a triquíase e o ectrópio foram mais relacionadas às características homens, brancos, queixa de redução de acuidade visual para perto. Foi realizado tratamento cirúrgico em 72,7% das triquíases detectadas, assim como 28,5% dos ectrópios. Já os casos de ptose palpebral foram relacionados ao sexo feminino, brancas, com queixa de diminuição da acuidade visual para perto e 26,3% necessitaram de cirurgia. Entrópio foi detectado em um caso, masculino, branco e epibléfaro foi observado em um indivíduo do sexo feminino, parda. Conclusão: A alteração palpebral mais presente na população geral brasileira é a triquíase, seguida da ptose palpebral e do ectrópio. Os autores chamam a atenção para o fato de os portadores não possuírem queixas relacionadas às alterações palpebrais.

Purpose: to show the frequency of occurrence of the eyelid disorders in a Brazilian population sample, as well as the characteristics of the carriers. Methods: a transversal study using a random population sample was carried out in the years 2004/2005, involving nine cities of the middle west region of the State of São Paulo - Brazil. We had 7654 participants which were evaluated according to demographic variables and complete ophthalmological examination. The eyelid disorders were detected using a lantern and slit lamp. Data were statistically analyzed. Results: eyelid disorders such as of trichiasis and ectropion were more related to the characteristics men, whites, complaining of reduced near visual acuity and 72.7% of trichiasis underwent surgical treatment, as well as 28.5% of patients with ectropion. Ptosis was related to the females, whites, complaining of reduced near visual acuity and 26.3% required surgery. Entropion was detected only in one case, male, white and a case of epiblepharon was observed in a female, brown. Conclusion: the most frequent palpebral disorder observed in the Brazilian general population is trichiasis, followed by ptosis and ectropion. The authors call attention to the fact that carriers do not have complaints related to the eyelid disorders.

Demodex folliculorum on the eyelash follicule of diabetic patients / Demodex folliculorum nos cílios de pacientes diabéticos

PURPOSE: To compare the prevalence of Demodex folliculorum on the eyelashes of patients with proliferative diabetic retinopathy and healthy voluntaries. METHODS: Type 2 diabetic patients with proliferative retinopathy and age- and gender-matched healthy voluntaries (group control) underwent a slit lamp examination which three eyelashes containing cylindrical dandruff were removed from each lid by fine forceps. The lashes were dyed with fluorescein and the presence of Demodex folliculorum was verified by direct visualization under a light microscope. The mites were recognized based on its morphology and peculiar movement. The results were expressed in "positive" when at least one mite on one lash was found and "negative" when no mite was identified. The Chi-square test was used for comparing mites' presence in both groups. RESULTS: Forty-two patients were included in each group. The age ranged from 50 to 60 years old, with a mean of 56.4 ± 5.2 years. The male:female ratio was 0.6:1. There was no statistically significant difference with regard to age and gender in both groups (p>0.05). Demodex folliculorum was significantly more prevalent in diabetic patients (54.8 percent) than in control patients (38.1 percent) (p=0.048). CONCLUSION: Demodex folliculorum was more prevalent in diabetic patients than in healthy voluntaries, independently of gender and age.

OBJETIVO: Comparar a prevalência de Demodex folliculorum nos cílios de pacientes com retinopatia diabética proliferativa e voluntários normais. MÉTODOS: Pacientes com diabetes mellitus tipo 2 apresentando retinopatia proliferativa e voluntários normais com mesma distribuição de sexo e idade (grupo controle) foram submetidos a exame em lâmpada de fenda. Três cílios com secreção "em colarete" foram removidos de cada pálpebra com pinça delicada. Os cílios foram corados com fluoresceína e a presença de Demodex folliculorum foi verificada por visualização direta através de microscópio de luz. As larvas foram reconhecidas baseadas em sua morfologia e movimentos peculiares. Os resultados foram expressos em "positivo" quando foi encontrada pelo menos uma larva em um cílio e "negativo" quando nenhuma larva foi encontrada. O teste de Chi quadrado foi utilizado para comparar a presença das larvas nos dois grupos. RESULTADOS: Quarenta e dois pacientes foram incluídos em cada grupo. A idade variou de 50 a 60 anos com média de 56,4 ± 5,2 anos. A relação masculino:feminino foi de 0,6:1. Não houve diferença estatisticamente significante com relação ao sexo e idade entre os dois grupos (p>0,05). Demodex folliculorum foi significantemente mais prevalente em pacientes com diabetes (54,8 por cento) que no grupo controle (38,1 por cento) (p=0,048). CONCLUSÃO: Demodex foliculorum foi mais prevalente em pacientes diabéticos que em voluntários normais, independentemente do sexo e da idade.

Complications in blepharoplasty: how to avoid and manage them / Complicações em blefaroplastia: como evitá-las e corrigi-las

Complications in blepharoplasty are uncommon and, when they occur, they are usually mild and transient, such as hematomas and chemosis. However, sometimes they can be severe, such as blindness, or they might require surgical correction, such as ectropion. OBJECTIVE: To evaluate the results and complications of transcutaneous blepharoplasty performed in the same procedure, discussing how to treat and how to avoid them. METHODS: A retrospective study of 200 medical records of consecutive patients that underwent transcutaneous blepharoplasty from January 2007 to January 2009. The variables analyzed were age, gender, complications, clinical outcome, patient satisfaction, and photographic documentation. RESULTS: The incidence of complications was 9.5 percent (19 patients). The complications were 1 hematoma, 12 cases of chemosis and 13 patients who underwent canthoplasty, 6 patients with malposition of the lower eyelid (5 retractions and 1 ectropion). Medical treatment was performed in 12 patients and revision surgery in 7 cases of all the patients who had complications. CONCLUSIONS: We demonstrated that blepharoplasty is a procedure with a high satisfaction and a low complication rate, and it is an excellent surgical procedure, when properly indicated.

As complicações em blefaroplastia não são comuns e quando ocorrem são geralmente discretas e transitórias, como hematoma e quemose. Entretanto, algumas vezes podem ser definitivas, como cegueira, ou necessitarem de novas abordagens cirúrgicas para correção, como ectrópio. OBJETIVO: Avaliar resultados e complicações das blefaroplastias transcutâneas realizadas em um mesmo serviço, demonstrando como tratá-las e evitá-las. CASUÍSTICA E MÉTODO: Estudo retrospectivo de 200 prontuários de pacientes consecutivos submetidos à blefaroplastia transcutânea entre o período de janeiro de 2007 a janeiro de 2009 em um mesmo serviço. As variáveis analisadas foram: idade, sexo, complicações, evolução clínica, grau de satisfação e documentação fotográfica. RESULTADOS: A incidência de complicações foi de 9,5 por cento (19 pacientes). As complicações encontradas foram: 1 hematoma, 12 casos de quemose, sendo que esta ocorreu em 61,5 por cento dos 13 pacientes que realizaram cantoplastia, 6 pacientes com mau posicionamento de pálpebra inferior, sendo que, destes, 5 correspondem à retração e 1 ao ectrópio. Foi realizado tratamento clínico com acompanhamento ambulatorial em 12 pacientes e cirurgia revisional em 7 casos do total de pacientes com complicações. CONCLUSÕES: Demonstrou-se que a blefaroplastia é uma cirurgia com alta taxa de satisfação e baixo número de complicações, sendo um excelente procedimento cirúrgico, quando corretamente indicada.

Floppy eyelid syndrome: review / Síndrome da frouxidão palpebral: revisão da literatura

Floppy eyelid syndrome is characterized by the easy evertion of the upper eyelid which occurs spontaneously during the sleep, causing the exposure of the eye surface and chronic papillary conjunctivitis. Its pathogenesis is not totally defined yet: it is usually more frequent in middle-aged, male obese patients and it is associated with systemic disorders such as obstructive sleep apnea, high blood pressure and diabetes. On the occasions which conservative treatment fails, surgical procedures present good results, including surgical techniques which are constantly evolving.

A síndrome de frouxidão palpebral é caracterizada pela fácil eversão da pálpebra que ocorre espontaneamente durante o sono causando exposição dos olhos, com consequente conjuntivite papilar crônica. Sua patogênese ainda não está totalmente definida e é mais comum em pacientes masculinos, obesos, de meia idade e está associada a doenças sistêmicas como apnéia obstrutiva do sono, hipertensão arterial e diabetes. Quando o tratamento clínico não apresenta boa resposta, procedimentos cirúrgicos apresentam bons resultados, com técnicas em constante evolução.
