Long-term outcomes of modified transcanalicular diode laser dacryocystorhinostomy

ABSTRACT Purpose: The purpose of this study is to assess the long-term outcomes of modified transcanalicular diode laser dacryocystorhinostomy in a large cohort of patients affected by primary acquired nasolacrimal duct obstruction. Methods: This study, conducted from January 17 to June 2022, encompassed 141 patients (159 procedures) who underwent modified transcanalicular diode laser dacryocystorhinostomy (MT-DCR). The procedure employed an 810-nm diode laser. Patients were monitored for at least a year after the intervention. Anatomical success was determined by ostium patency upon irrigation, while functional success referred to epiphora resolution. Parameters studied included patient demographics, procedure duration, complications, and both anatomical and functional success. Statistical analysis was performed using the Statistical Package for the Social Sciences software, with results considered significant at a 95% confidence interval (p≤0.05). Results: A total of 159 lacrimal drainage systems (141 patients: 112 women and 29 men) were included in this study. Among them, 18 underwent bilateral procedures. The average patient age was 58 years (range: 34-91 years), and the average surgical duration was 24 minutes (range: 18-35 minutes). One year after the surgery, MT-DCR exhibited anatomical and functional success rates of 84.9% (135/159) and 83% (132/159), respectively. Conclusion: MT-DCR achieved an anatomical success rate of 84.9%, reflecting an excellent outcome. However, further extensive studies with larger sample sizes and longer follow-up periods are necessary to substantiate these findings.

Acute dacryocystitis retention: a case report and literature review / Dacriocistite aguda de retenção: relato de caso e revisão da literatura

ABSTRACT Acute dacryocystitis retention (ADR) is an unusual entity that contributes to an incorrect diagnosis and treatment. We describe a case of acute dacryocystitis retention occurring in a 61-year-old diabetic male who presented with severe pain, swelling, and inflammatory signs above the left medial canthal ligament tendon. He had no previous history of epiphora. Computed tomography scan indicated acute dacryocystitis. Clinical treatment resulted in complete resolution of the condition. Syringing one month after the acute episode indicated a patent lacrimal excretory system. The temporary obstruction that evolved to an acute dacryocystitis retention was probably secondary to nasal alteration or supposed dacryoliths. Timely, conservative clinical treatment can lead to complete resolution of acute dacryocystitis retention with no further treatments.

RESUMO A dacriocistite aguda de retenção é uma entidade incomum, o que contribui para que o diagnóstico e o tratamento não sejam corretos. Estamos descrevendo um caso de dacriocistite aguda de retenção ocorrendo em um homem diabético de 61 anos que apresentou dor intensa, edema e sinais inflamatórios acima do tendão cantal medial esquerdo. Ele não tinha histórico anterior de epífora. A tomografia computadorizada indicou dacriocistite aguda. O tratamento clínico resultou na resolução completa da condição. A irrigação, um mês após o episódio agudo, indicou sistema excretor lacrimal pérvio. A obstrução temporária que evoluiu para uma dacriocistite aguda de retenção foi provavelmente secundária a alteração nasal ou supostos dacriolitos. O tratamento clínico conservador pode levar à resolução completa da dacriocistite aguda de retenção, sem necessidade de outros tratamentos.

Efficacy of mitomycin C in modified transcanalicular diode laser dacryocystorhinostomy / Eficácia da mitomicina C na dacriocistorrinostomia transcanalicular com laser diodo modificada

ABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.

RESUMO Objetivo: Avaliar a eficácia da mitomicina C no sucesso anatômico e funcional após dacriocistorrinostomia transcanalicular com laser de diodo. Métodos: Estudo prospectivo, duplo-cego, randomizado e controlado por placebo. Comparou o efeito da mitomicina C tópica na dacriocistorrinostomia transcanalicular com laser de diodo. No Grupo 1, foi utilizada apenas solução salina tópica, enquanto no Grupo 2 foi utilizada mitomicina C tópica. O sucesso foi definido como permeabilidade da via lacrimal e alívio dos sintomas ao final de 6 meses. Resultados: Seis meses após a cirurgia, o Grupo 1 (30 pacientes) apresentou taxas de sucesso anatômico e funcional de 86,7% e 83,3%, respectivamente. O Grupo 2 (32 pacientes) apresentou taxas de sucesso anatômico e funcional de 87,5% e 84,3%, respectivamente. Não houve diferença estatística significante entre os Grupos 1 e 2 (p=1,000). Conclusão: O uso de mitomicina C não melhora as taxas de sucesso anatômico e funcional do dacriocistorrinostomia transcanalicular com laser de diodo em comparação ao placebo.

Chronic unilateral tearing as a sign of lacrimal sac squamous cell carcinoma / Lacrimejamento unilateral crônico como sinal de Carcinoma espinocelular de saco lacrimal

ABSTRACT Tearing is a very common symptom in ophthalmic practice; however, this issue is commonly overlooked. The authors describe the case of a patient with chronic unilateral epiphora that had been neglected for 8 y; lacrimal system workup was performed for this patient only because of dacryocystitis evolvement. Following the diagnosis of nasolacrimal duct blockage, dacryocystorhinostomy was indicated. Intraoperative abnormal mucosa was subjected to biopsy, and a diagnosis of squamous cell carcinoma in the lacrimal sac was established. Extended tumor excision was performed for the patient and adjuvant radiotherapy was administered, without any recurrence till the 2-year follow-up. The present report highlights the relevance of a detailed evaluation for determining the underlying causes of tearing, especially in chronic unilateral presentation. The consideration of potential malignancy in such cases could prevent delayed diagnosis of uncommon but potentially life-threatening malignancies of the lacrimal drainage system.

RESUMO O lacrimejamento é um sinal comum na prática oftalmológica, porém frequentemente negligenciado. Os autores descrevem um caso de um paciente com epífora unilateral direita com 8 anos de história que só após evoluir com dacriocistite foi submetido a semiologia de vias lacrimais. Após o diagnóstico de obstrução baixa da via lacrimal foi submetido a cirurgia de dacriocistorrinostomia, onde o saco lacrimal de aparência atípica foi biopsiado e identificado como carcinoma espinocelular. O paciente foi submetido a ressecção oncológica do tumor seguido de radioterapia adjuvante, permanecendo livre de recidiva por 2 anos. Este caso ressalta a importância de investigar causas da epífora, especialmente quando unilateral, dada sua maior associação com a obstrução de via lacrimal. Uma semiologia oportuna das vias lacrimais podem evitar atrasos no diagnóstico de obstrução secundárias a neoplasia, que apesar de incomuns, são potencialmente fatais.

Rhinosporidiosis of the lacrimal sac masquerading as chronic dacryocystitis: a rare presentation

Rhinosporidiosis is a chronic infection of the mucous membrane caused by the Rhinosporiduim seeberi, which infects through transepithelial penetration. Although described worldwide, this entity is mostly found in the western hemisphere, afflicting young people, predominantly males, associated in many cases with recreational or professional contact with bath in ponds, rivers, or stagnant waters. The clinical features are varied depending on the affected membrane, in some cases mimicking other diseases postponing the correct diagnosis. Although nasal obstruction and epistaxis are the common clinical presentations in sinonasal rhinosporidiosis, patients with epiphora without a nasal mass often challenge the diagnosis. In the present case, we have documented a case of isolated lacrimal sac rhinosporidiosis masquerading as chronic dacryocystitis, which was successfully managed by endoscopic excision, accompanied by a literature review.

Pilomatrix carcinoma of the lacrimal caruncle: a case report / Carcinoma pilomatricial da carúncula lacrimal: relato de caso

ABSTRACT A 45-year-old man presented with a 3-month history of a mass located in the caruncle of his right eye. An incisional biopsy had been performed one month prior by another specialist, and the histopathology report showed basal cell carcinoma. The mass was completely excised with a 2 mm safety margin, and the large conjunctival defect was reconstructed with one sheet of amniotic membrane allograft. A histological diagnosis of pilomatrix carcinoma was established. To prevent recurrence after surgery, we added bevacizumab (25 mg/mL, 1.25 mg/mL per drop) eye drops four times per day for three months. At the one-year follow-up, the patient showed no evidence of local recurrence or distant metastasis after initial excision and remains under close follow-up. Pilomatrix carcinoma should be considered in the differential diagnosis of a caruncular mass.

RESUMO Um homem de 45 anos apresentou história de massa na carúncula no olho direito durante 3 meses. Uma biópsia incisional foi realizada 1 mês antes por outro especialista e o laudo histopatológico mostrava carcinoma basocelular. A massa foi completamente excisada, com uma margem de segurança de 2 mm, e a grande lesão conjuntival foi reconstruída com uma folha de aloenxerto de membrana amniótica. Foi estabelecido um diagnóstico histológico de carcinoma pilomatricial. Para evitar a recorrência após a cirurgia, adicionamos colírio de bevacizumabe (25 mg/mL, 1,25 mg/mL por gota) quatro vezes ao dia durante três meses. No seguimento de 1 ano, o paciente não apresentou evidência de recidiva local ou metástase distante após a excisão inicial e continua sob acompanhamento próximo. O carcinoma pilomatricial deve ser considerado no diagnóstico diferencial de uma massa caruncular.

Reliability of endoscopic dye transit test for prediction of functional success after diode laser and external dacryocystorhinostomy / Confiabilidade do teste endoscópico do corante na predição do sucesso funcional após dacriocistorinostomia com laser diodo e externa

ABSTRACT Purpose: To determine the reliability of the endoscopic dye transit test for the prediction of functional success after dacryocystorhinostomy. Methods: A cross-sectional study was conducted with 50 patients who underwent external dacryocystorhinostomy Group or transcanalicular dacryocystorhinostomy Group and had anatomically patent ducts during irrigation, with a minimum 6-month follow-up. The external dacryocystorhinostomy, defined as the time from instillation of the dye into the conjunctival sac until its flow from the rhinostomy site, was performed in all patients. Positive predictive value of the endoscopic dye transit test to assess functional success was analyzed. The cutoff point was determined using a receiver operating characteristic curve. Results: Of the 50 patients, 44 (88%) exhibited subjective improvement or complete resolution of epiphora (functional success). The best cutoff point for the endoscopic dye transit test was 60 s. Of 39 patients with endoscopic dye transit test £60 s, 38 (97.4%) exhibited functional success, demonstrating a 97.4% positive predictive value. Conclusion: The endoscopic dye transit test £60 s is a reliable tool to predict functional success and good prognosis after external or laser transcanalicular dacryocystorhinostomy.

RESUMO Objetivo: Determinar a confiabilidade do teste endoscópico do corante na predição do sucesso funcional após dacriocistorrinostomia. Métodos: Estudo transversal com 50 pacientes submetidos ao grupo de dacriocistorrinostomia externa ou grupo dacriocistorrinostomia transcanalicular e que possuíam dutos anatomicamente patentes pela irrigação, com seguimento mínimo de 6 meses. A dacriocistorrinostomia externa, definida como o tempo desde a instilação do corante no saco conjuntival até o fluxo do local da rinostomia, foi realizada em todos os pacientes. O valor preditivo positivo do teste endoscópico do corante para avaliar o sucesso funcional foi analisado. O ponto de corte foi determinado usando uma curva característica de operação do receptor. Resultados: Dos 50 pacientes, 44 (88%) apresentaram melhora subjetiva ou resolução completa da epífora (sucesso funcional). O melhor ponto de corte para o teste endoscópico do corante foi de 60 s. Dos 39 pacientes com teste endoscópico do corante £60 s, 38 (97,4%) apresentaram sucesso funcional, demonstrando um valor preditivo positivo de 97,4%. Conclusão: O teste en­doscópico do corante £60 s é uma ferramenta confiável para predizer o sucesso funcional e o bom prognóstico após dacriocistorrinostomia transcanalicular externa ou a laser.

Silicone perforated punctal plugs for the treatment of punctal stenosis / Tampões perfurados de silicone no tratamento da estenose do ponto lacrimal

ABSTRACT Purpose: Punctal stenosis can result in symptoms such as epiphora and can significantly reduce the quality of life of patients. Perforated punctal plug insertion is an easy procedure that is commonly used as the first step of treatment for punctal stenosis. Methods: Clinical, demographic, and outcome data were retrospectively collected for 54 eyes of 21 males and 11 females who consecutively presented to our Oculoplastic Clinic and underwent silicone Micro Flow perforated punctal plug insertion. All patients had epiphora with punctal stenosis. Results: Of the 54 plugs, 26 plugs (48.1%) were lost and 28 (51.8%) stayed in place. Of the latter, eight were explanted because of the occlusion of the plug with secretions and recurrent conjunctivitis; moreover, two plugs migrated deep into the vertical canaliculus. Of the 54 plugs, only 18 (33.3%) were well-tolerated with significant symptomatic improvement. Conclusion: Plug loss is a prominent problem in patients implanted with perforated punctal plugs. Silicone punctal plugs failed in 66.7% of our patients over a mean follow-up of 14.2 months.

RESUMO Objetivo: A estenose punctal pode resultar em sintomas como a epífora e diminuir significativamente a qua­lidade de vida dos pacientes. A inserção de um tampão perfurado é um procedimento fácil que é comumente usado como o primeiro passo do tratamento para a estenose punctal. Métodos: Dados clínicos, demográficos e de resultado foram coletados retrospectivamente de 54 olhos de 21 homens e 11 mulheres que consecutivamente se apresentaram em nossa Clínica de Oculoplástica e foram submetidos a inserção de um tampão de silicone perfurado Micro Flow. Todos os pacientes tinham epífora com estenose punctal. Resultados: Dos 54 tampões, 26 (48,1%) foram perdidos e 28 (51,8%) permaneceram no local. Destes últimos, 8 foram removidos devido a oclusão do tampão com secreção e conjuntivite recorrente, além disso, 2 migraram profundamente no canalículo vertical. Dos 54 tampões, apenas 18 (33,3%) foram bem tolerados com significativa melhora dos sintomas. Conclusão: A perda de tampões é um problema de destaque em pacientes implantados com tampões perfurados. Tampões de silicone falharam em 66,7% dos pacientes durante um seguimento médio de 14,2 meses.

Recommendations from the Brazilian society of rheumatology for the diagnosis of Sjögren's syndrome (Part I): glandular manifestations (systematic review)

Abstract Background: Primary Sjögren's syndrome (pSS) is a systemic immune-mediated disease whose main characteristic is exocrine gland inflammation and, subsequent reduction in tear and saliva production. A delayed diagnosis is common due to the nonspecific clinical manifestations of disease. The aim of the present study was to develop recommendations for the diagnosis of glandular manifestations of pSS based on evidence and expert opinion. Main body of the abstract: We conducted a systematic literature review to retrieve the best evidence available on the accuracy of diagnostic tests for pSS. We also held two in-person meetings with experts (rheumatologists, pathologists, ophthalmologists and dentists) to establish their level of agreement using the Delphi method. Ultimately, we generated 18 recommendations that aim to facilitate the diagnosis of the glandular manifestations of pSS. Conclusion: The diagnosis of glandular manifestations of pSS is complex and multidisciplinary. It requires specific knowledge in the field of ophthalmology, immunology, pathology and imaging, making it compulsory for the rheumatologist to work with professionals from these different areas in order to improve accuracy and early diagnosis. Glandular dysfunction tests, ANA, RF, Anti-Ro, protein electrophoresis, urinalysis, blood count, C-Reactive protein, complement, testing for syphilis and viruses (HCV, HIV) and SGUS should be investigated when dryness or systemic manifestation are present. Minor salivary gland biopsy is recommended for all anti-Ro negative or incomplete criteria cases.

Outcome of External Dacryocystorhinostomy and Monocanalicular Intubation in Patients with Total Obstruction of One Canalicus

PURPOSE: We sought to evaluate the outcomes of external dacryocystorhinostomy (DCR) and mono-canalicular intubation in patients with total obstruction of one canalicus. METHODS: Sixteen eyes of 16 patients with nasolacrimal duct obstruction and a single canaliculus obstruction who had undergone external DCR and monocanalicular intubation of the intact canaliculus were retrospectively included in the present study. The monocanalicular tube (Mini Monoka) was left in place for at least two months. Munk epiphora grading for the evaluation of epiphora and irrigation was performed both preoperatively and at 6 months postoperatively. RESULTS: Mean patient age was 46 ± 14.2 (range, 18 to 76) years. The inferior canaliculus was obstructed in nine eyes (group A) and the superior canaliculus was obstructed in seven eyes (group B), respectively. Eight eyes had chronic dacryocystitis and two of these eyes also had a history of acute dacryocystitis attack. Mean preoperative Munk scores were 3.89 in group A and 4.0 in group B. Ocular surface irritation occurred in one eye in group A. Artificial eye drops were prescribed and early tube removal was not performed. Spontaneous tube dislocation was recorded in one eye in group B. No other corneal, punctal, or canalicular complications were found. At six months, irrigation of intact canaliculus was patent in all eyes. Mucoid discharge, conjunctival hyperemia, and chronic conjunctivitis were also resolved. Postoperative Munk scores were 1.11 ± 0.9 in group A and 0.86 ± 0.9 in group B. Of note, preoperative and postoperative Munk scores were significantly different in both groups (group A, p = 0.006; group B, p = 0.017). The postoperative Munk scores were not statistically different between the two groups (p = 0.606). CONCLUSIONS: In patients with nasolacrimal duct obstruction and a total of one canaliculus obstruction, external DCR and monocanalicular intubation of the intact canaliculus is an effective surgical option.

Objective To evaluate the effect and safety of acupuncture combined with Mingmu-Dihuang pill in patients with dry eyes.Methods A total of 100 patients with dry eye were enrolled in line with the inclusion criteria and divided into experimental group and control group by random figure table.The experimental group was treated with acupuncture combined with Mingmu-Dihuang pill,and the control group was treated with artificial tears.After 2 months of treatment,the Schirmer test (schirmerI,SIT),tear film break up time (BUT),fluorescent staining (FL) and clinical symptom score were observed and compared,and the clinical efficacy and safety were evaluated.Results The total effective rate of the experimental group was 89.0％ (89/100) and the control group was 67.0％ (67/100),and the difference was significant (x2=14.121,P＜0.001).After treatment,the levels of BUT (7.89 ± 1.65 s vs.5.01 ± 1.72 s,t=8.543),SIT (7.45 ± 1.68 mm vs.5.01 ± 1.72 mm,t=5.991) in the experimental group were significantly higher than those of the control group,and the difference is significant (P＜0.01).The FL score and dry eye score in the experimental group were significantly lower than those of the control group (t were 11.551,12.342,P＜0.01).Conclusions Acupuncture combined with Mingmu-Dihuang pill has better clinical effect and good safety for the treatment of dry eye patients.

Clinical study of Xiaoyaosan and Shengmaiyin combined with conventional western medicine in the treatment of xerophthalmia / 国际中医中药杂志

Objective To evaluate the effect of Xiaoyaosan and Shengmaiyin combined with conventional western medicine for xerophthalmia.Methods A total of 76 xerophthalmia patients who met the criteria were divided into two groups according to random number table,with 38 cases in each group.The control group was treated with routine western medicine,while the observation group was treated with Xiaoyaosan combined with Shengmaiyin on the basis of the control group.Both groups were treated for 4 weeks.Before and after treatment,the symptoms were scored,and the tear film stability was evaluated according to the results of fluorescent test (FL),breakup time of tear film (BUT) and schirmer Ⅰ test (SIT).The contents of IL-1β,IL-6 and TNF-α in tear were detected by ELISA,and the clinical efficacy was evaluated.Results The total effective rate was 92.9％ (65/70) in the observation group and 76.4％ (55/72) in the control group,and there was significant difference between the two groups (Z=-2.991,P=0.002).After treatment,the SIT (6.9 ± 0.8 mm vs.4.3 ± 0.5 mm,t=3.751),BUT (10.5 ± 1.6 s vs.6.4 ± 0.8 s,t=4.228) in the observation group were significantly higher than those in the control group (P＜0.05).The FL score (0.9 ± 0.1 vs.1.4 ± 0.2,t=3.208) in the observation group was significantly lower than that of the control group (P＜0.05).The scores of aningeresting,foreign body sensation,visual fatigue,photophobia and visual blur in the observation group were significantly lower than those in the control group (t were 3.559,4.015,4.119,3.983,4.120,all Ps＜0.05).The levels of IL-1β,IL-6 and TNF-α in tear were significantly lower than those in control group (t were 11.887,8.028,8.112,all Ps＜0.001).Conclusions The Xiaoyaosan combined with Shengmaiyin can improve tear film stability,relieve local ocular surface inflammation and improve clinical symptoms in patients with xerophthalmia.

Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis / Linfoma MALT primário, bilateral e simétrico do saco lacrimal simulando dacriocistite crônica

Abstract We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin's Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.

Resumo Descrevemos um caso de um linfoma MALT bilateral, simétrico e primário de saco lacrimal. O linfoma MALT é um subtipo do Linfoma Não-Hodkin dos anexos oculares. Quando o local primário do linfoma é o saco lacrimal, ele pode simular uma dacriocistite crônica. Essa situação pode atrasar o diagnóstico e ter consequências fatais.

The relationship between topical anti-glaucoma medications and the development of lacrimal drainage system obstruction / A relação entre medicamentos tópicos anti-glaucoma e o desenvolvimento de obstrução do sistema de drenagem lacrimal

ABSTRACT Purpose: To evaluate whether any topical anti-glaucoma medications increase the risk of lacrimal drainage system obstruction or whether the presence of preservatives alone is sufficient to generate obstruction. Methods: This nested case-control study compared a group of patients with lacrimal duct obstruction who received topical anti-glaucoma medications to a control group of patients without obstruction. Results: The medical records of 255 patients with glaucoma who consulted the Oculoplastic Section with complaints of watery eyes were reviewed. Among these patients, 59 exhibited lacrimal drainage obstruction. Ninety-four percent of patients with lacrimal drainage obstruction used beta-blockers, and 41% used prostaglandin analogs. A logistic regression model was used to adjust for age, sex, and the use of other medications. No significant differences were observed regarding the topical anti-glaucoma medications used between groups. Conclusion: No single topical anti-glaucoma medication demonstrated a stronger association with the development of lacrimal duct obstruction.

RESUMO Objetivo: Avaliar se algum medicamento tópico anti-glaucoma aumenta o risco de obstrução do sistema de drenagem lacrimal ou se a presença de conservantes é su fi cien te para gerar obstrução. Métodos: Este estudo de caso-controle aninhado comparou um grupo de pacientes com obstrução do ducto lacrimal que receberam medicações tópicas anti-glaucoma contra um grupo controle de pacientes sem obstrução. Resultados: Foram revistos os prontuários de 255 pacientes com glaucoma que consultaram a Seção de Oculoplástica com queixas de olhos lacrimejantes. Dentre esses pacientes, 59 apresentavam obstrução da via lacrimal de drenagem. Noventa e quatro por cento dos pacientes com obstrução usaram betabloqueadores e 41% usaram análogos de prostaglandinas. Um modelo de regressão logística foi utilizado para ajustar a idade, sexo e o uso de outros medicamentos. Não foram observadas diferenças significativas em relação às medicações tópicas anti-glaucoma usadas entre os grupos. Conclusão: Nenhum medicamento anti-glaucoma tópico único demonstrou uma associação mais forte com o desenvolvimento de obstrução do ducto lacrimal.

Solitary fibrous tumor of the lacrimal gland mimicking pleomorphic adenoma / Tumor fibroso solitário de glândula lacrimal simulando adenoma pleomórfico

ABSTRACT Solitary fibrous tumor (SFT) is a rare mesenchymal spindle-cell neoplasm commonly found in the pleura; it is rare in the orbit and extremely rare in the lacrimal gland. We herein report a case of SFT of the lacrimal gland that mimicked a pleo morphic adenoma. We discuss the clinical, radiological, histopathological, and immunohistochemical findings that provided insight and rationale to accurately diagnose this case.

RESUMO Os autores relatam um caso de tumor fibroso solitário (TFS) de glândula lacrimal simulando um adenoma pleomórfico. O TFS é um raro tumor mesenquimal de células fusiformes, comumente encontrado na membrana pleural, raramente en contrado na órbita e extremamente raro na glândula lacrimal. Os autores discutem os achados clínicos, radiológicos, histológicos e imunohistoquímicos que são a chave para o correto diagnóstico desta rara entidade.

Dacriocistorrinostomia endoscópica transnasal / Transnasal endoscopic dacryocystorhinostomy

Desde hace muchos años la vía lagrimal la han compartido dos disciplinas: la otorrinolaringología y la oftalmología. Con el paso del tiempo se han desarrollado diferentes técnicas encaminadas al manejo de la patología de la vía nasolagrimal desde la tradicional vía externa hasta los procedimientos asistidos con Láser. La DCR (dacriocistorrinostomia) endoscópica es al día de hoy el procedimiento ideal para el manejo de la insuficiencia y la estenosis de la vía lagrimal, derivado de traumas, dacriocistitis o disfunción de la vía nasolagrimal. Presentamos el reporte de nuestra experiencia en el manejo de estos trastornos en conjunto con el servicio de oftalmología en el Hospital de Ecopetrol de Barrancabermeja, dando especial relevancia a la técnica quirúrgica y a los resultados posoperatorios evitando la morbilidad de la dacriocistorrinostomia externa.

During long time, the lacrimal pathway has been studied and treated by two specialties. Otolaryngology and ophthalmology. As time has gone by, different techniques for treating the lacrimal pathway have been developed, such as the traditional external approach and the laser assisted procedures. Nowadays, endoscopic DCR (dacryocystorhinostomy) is the ideal procedure for treating the lacrimal pathway insufficiency and stenosis secondary to trauma, dacryocystitis or dysfunction of the nasolacrimal pathway. We report our experience in the management of these disorders with the Ecopetrol Hospital in Barrancabermeja's Ophthalmology service, giving special relevance to the surgical technique and the postoperative results avoiding the morbidity of the external dacryocystorhinostomy.

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.

Definition and treatment of lacrimal drainage disease

Epiphora is one of the most common problems in ophthalmological practice, and is caused by dysfunction of the lacrimal pathway. The lacrimal drainage system is a continuous anatomical structure consisting of the lacrimal punctum, inferior and superior canaliculi, common canaliculus, lacrimal sac, and nasolacrimal duct. Lacrimal disease can be medically treated in case of acute inflammation or partial obstruction at the beginning of treatment, but surgical treatment is necessary in most cases. This paper discusses the etiology, clinical features, diagnosis, and surgical treatment of various lacrimal diseases through a selective review of the relevant literature. Advances in lacrimal duct surgery can now be performed in such a way that the structural integrity and normal physiological function of the entire efferent lacrimal pathway is preserved.
