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.

Outcomes of lacrimal punctal tumors treated with a superpulse CO2 laser.

Literature on lacrimal punctal tumors is limited due to their rarity. Our aim in this study was to evaluate the clinicopathological characteristics of these tumors and assess functional and aesthetic outcomes after CO2 laser ablation with silicone stent intubation. A retrospective consecutive study was conducted from December 2013 to November 2020. All patients who received CO2 laser ablation with silicone intubation for their punctal tumors at National Cheng Kung University Hospital, a tertiary hospital in Taiwan, were included in this study. Demographic and clinical information was gathered during preoperative and follow-up visits. Thirty-three Han Chinese patients with a solitary punctal tumor were included in this study. Demographically, we found a female predominance (75.8%), and most tumors were located at the lower punctum (69.7%). The incidence of melanocytic nevus was higher in punctal tumors (78.8%) than in benign eyelid tumors (22.3%). Irrigation tests were performed in the 33 patients during follow-up visits, all of whom exhibited patency of the lacrimal system. No patient complained of epiphora after surgery. Thirty-two patients (97%) were satisfied with the aesthetic outcome after surgery. Superpulse CO2 laser ablation followed by silicone stent intubation is a safe and effective treatment for benign punctal tumors. In addition, compared to those of eyelid tumors, the clinicopathological characteristics of lacrimal punctal tumors are different, and melanocytic nevus was the main cause of these tumors.

Differentiation of lacrimal gland tumors using the multi-model MRI: classification and regression tree (CART)-based analysis.

BACKGROUND: Little is known about the value of dynamic contrast-enhanced (DCE) in combination with diffusion-weighted imaging (DWI) for the differentiation of lacrimal gland tumors. PURPOSE: To evaluate the ability of DCE and DWI in differentiating lacrimal gland tumors. MATERIAL AND METHODS: DCE and DWI were performed in 72 patients with lacrimal gland tumors. Time-intensity curve (TIC) patterns were categorized as type A, type B, type C, and type D. Apparent diffusion coefficient (ADC) was measured on DWI. Then, the diagnostic effectiveness of TIC in conjunction with ADC was assessed using classification and regression tree (CART) analysis. RESULTS: Type A tumors were all epithelial; they could be further separated into pleomorphic adenoma sand carcinomas. Type B tumors were all non-epithelial tumors, which could be further separated into benign inflammatory infiltrates (BIIs) and lymphomas. Type C tumors contained both carcinomas and non-epithelial tumors, which could be diagnosed into carcinomas, BIIs and lymphomas. Type D tumors were all PAs. The mean ADC of epithelial tumors was significantly higher than that of non-epithelial tumors, and the mean ADC values were significantly different between PAs and carcinomas. Besides, the mean ADC value of BIIs was higher than that of lymphomas. Therefore, the CART decision tree made by ADC and TIC had a predictive accuracy of 86.1%, differentiating lacrimal gland tumors effectively. CONCLUSION: Combined DCE and DWI-MRI can efficiently differentiate lacrimal gland tumors which can be of help to ophthalmologists in the diagnosis and treatment of these tumors.

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.

Etiology of Epiphora.

PURPOSE: This study aimed to analyze the common causes of epiphora in Korean patients and their response to subsequent management. METHODS: We retrospectively analyzed the medical records of 180 patients who visited Kim's Eye Hospital for epiphora between December 2017 and January 2019. This study included 320 eyes of 180 patients. RESULTS: In the 320 eyes of 180 patients, the most common etiology of epiphora was reflex tearing due to dry eye syndrome, which occurred in 167 eyes (52.19%). The other etiologies of epiphora included anatomical abnormality (68 eyes, 21.25%), multifactorial (60 eyes, 18.75%), functional epiphora (14 eyes, 4.38%), ocular surface disease (seven eyes, 2.19%), and eyelid abnormality (four eyes, 1.25%). CONCLUSIONS: The most common etiology of epiphora in Korean patients was reflex tearing due to dry eye syndrome, followed by lacrimal passage abnormality, multifactorial, functional epiphora, anterior segment disease, and eyelid malposition. Most patients with reflex tearing reported improvement in their symptoms after lubrication.

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.

Meet the Lacrimal Sac: Endoscopic Surgeons' Road Map.

Knowledge of lateral nasal wall landmarks in relation to lacrimal apparatus is essential for successful endoscopic dacryocystorhinostomy. This descriptive study of right and left sagittally sectioned ten adult cadaver head specimens was done measuring various lateral nasal wall anatomical landmarks including lacrimal apparatus with digital calipers. Maxillary line was identified in 75%, majority overlapping lacrimal sac. Genu of middle turbinate was at or posterior to nasolacrimal duct. Mean distance of superior end of sac was 8.88 mm above axilla, between its anterior edge and axilla was 10.58 mm and its length was 11.72 mm. Considering above measurements, 'Rule of 10' can be applied for nasal mucosal incision. A "Three Tier Approach" to overcome mucosal (nasal), bony (lacrimal and frontal process of maxilla) and mucosal (sac) boundaries exposes lacrimal sac up to its inferior limit ensuring successful endonasal endoscopic dacryocystorhinostomy.

[A preliminary study on the clinical features of congenital lacrimal fistula].

Objective: To summarize the clinical characteristics of congenital lacrimal fistula for reference in its clinical diagnosis and treatment. Methods: Retrospective case series study. The clinical data of 27 patients (32 eyes) with congenital lacrimal fistula admitted to the Lacrimal Center of Third Medical Center of PLA General Hospital from July 2011 to November 2017 were analyzed, including gender, age of diagnosis, left eye or right eye, family history, physical examination, ophthalmic examination, fistula opening location and appearance, symptoms, results of lacrimal duct irrigation, three-dimensional reconstruction of the lacrimal drainage system with CT, lacrimal endoscopy, treatment, outcomes and follow-up. Results: In the 27 patients, the male to female ratio was 1∶2. The age of diagnosis was 1 to 74 years old, and the median was 32 years old. The ratio of unilateral fistula to bilateral fistula was 4.4∶1 (22/5), and the ratio of left eyes to right eyes was 1.2∶1 (12/10). The disease was sporadic in 22 patients, and 5 patients had a family history. Genetic analysis showed that congenital lacrimal fistula presented autosomal dominant inheritance. Fistulas were found on the skin surface of the lacrimal sac area under the medial canthus in 30 eyes, on the lacrimal caruncle in one eye, and on the conjunctiva of the medial canthus in one eye. All the patients presented with epihora, and irrigation liquid outflowed from the fistulas with purulence in 18 eyes. Lacrimal CT of the 27 patients showed contrast agents were left in the lacrimal sac. Lacrimal duct fistula was found open in the common canaliculus with concretions in the lacrimal system in four patients. Eight patients with mild symptoms underwent observation. Three patients underwent lacrimal therapeutic irrigation and probing. Sixteen patients underwent fistulectomy and were cured without recurrence during the follow-up of 1 to 6 years. Conclusions: Congenital lacrimal fistula is usually unilateral, and the opening is mostly located on the skin surface of the lacrimal sac area under the inner canthus ligament. Most cases are sporadic, and some cases are of familial inheritance in an autosomal dominant condition. (Chin J Ophthalmol, 2020, 56: 688-692).

Complete resolution of a large squamous cell carcinoma of the lacrimal duct in a young African American male after non-surgical management.

PURPOSE: The following case describes a 28-year old African American male who presented with squamous cell carcinoma of the lacrimal duct. Despite its size and location, his tumor showed complete resolution with non-surgical treatment. OBSERVATIONS: The patient presented with a 4-month history of dacryocystitis-like symptoms in the right eye, with no prior medical history and a history of tobacco smoking. Pathology indicated that SCC arose as nests within a benign sinonasal inverted papilloma. He received cisplatin chemotherapy and radiotherapy with tumor resolution in 4 months. Several months after the end of treatment, he experienced irreversible visual deterioration which led to enucleation of the right eye. The patient has remained in remission for 4 years following the treatment. CONCLUSIONS: The complete resolution of the mass with non-surgical management supports the most recent literature endorsing a multidisciplinary approach for localized tumors. Our patient is the only African American identified in the literature and the youngest reported patient to present with this tumor. Most case studies have not emphasized race, ethnicity and demographics, although it is known that morbidity in malignancy is impacted by these factors.

[Clinical and pathological analysis of 64 patients with primary neoplasms of the lacrimal drainage system].

Objective: To analyze the pathological classification and age distribution of primary neoplasms of the lacrimal drainage system. Methods: Retrospective case series study. A total of 64 patients (65 eyes) were diagnosed with primary neoplasms of the lacrimal drainage system and received surgery at Tianjin Eye Hospital from January 2006 to December 2016. All the clinical data of the patients were analyzed, including gender, diseased eye, age, clinical manifestations, composition of benign and malignant masses, and prognosis. The histopathological composition and age distribution of patients with primary lacrimal mass, lacrimal duct mass and lacrimal sac mass were analyzed according to the different diseased sites. Results: Twenty-three patients (24 eyes) were male, and 41 patients (41 eyes) were female. The right eye was involved in 36 patients, the left eye in 27 patients, and both eyes in one patient. The age at diagnosis ranged from 12 to 78 years old [mean, (46±4) years]. The course of disease was (13.1±4.2) months, ranging from 1 month to 7 years. The chief complaint was tear discharge in 43 patients, tumor in 19 patients, and abscess discharge in 2 patients. There were 29 patients with angular displacement and 21 patients with swelling pain. There were 51 patients with benign lesions, 4 with borderline lesions, and 9 with malignantlesions. These neoplasms consisted of primary peripunctal neoplasms in 17 patients, primary canalicular neoplasms in 2 patients, and primary lacrimal sac neoplasms in 45 patients. All primary peripunctal neoplasms (17 cases) were benign, among which nevi (10 cases) occupied the first place. All primary canalicular neoplasms (2 cases) were benign, there were 1 case of epidermoid cysts and 1 case of degenerative disease. Among the primary benign lacrimal sac masses (32 cases), mucous epithelial cysts (9 cases), dermoid cysts (6 cases), and epidermoid cysts (6 cases) occupied the first three places. Among the primary borderlin lacrimal sac masses (4 cases), there were 2 cases of giant cell tumor of soft tissue, 1 case of solitary fibrous tumor, and 1 case of inflammatory myofibroblastic tumor. The primary malignant mass of lacrimal sac (9 cases) was dominated by squamous cell carcinoma (3 cases). In terms of age distribution, the patients with primary peripunctal mass were mainly in the group of 40-59 years old (14 cases). The primary benign mass of lacrimal sac mainly occurred in the group of less than 40 years old (15 cases) and the group of 40-59 years old (11 cases). The patients with primary lacrimal sac borderline and malignant masses were all in the groups of over 40 years old. A total of 49 patients were followed up for 27 months to 16 years. The average follow-up time was (57.2±3.8) months. Lacrimal sac transitional cell carcinoma relapsed 7 months after surgery in one patient, and lacrimal sac melanoma relapsed 1 year after surgery in one patient. The patients did not relapse in 24 months and 38 months after surgery respectively. There were no recurrence of other cases. Conclusions: Primary peripunctal neoplasms are mostly characterized with benign lesions, among which nevi are most common. Mucous epithelial cysts, epidermoid cysts, and dermoid cysts are the major benign lacrimal sac neoplasms. Squamous cell carcinomas are the most common malignant lacrimal sac neoplasms. The malignant tumor of lacrimal sac often occurs in the middle-aged and elderly patients. (Chin J Ophthalmol, 2020, 56: 364-369).

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.

[Retrospective investigation of spontaneous bloody tears: a report of 27 cases].

Objective: To summarize clinical experience on the clinical feature, etiology and treatment of patients with spontaneous bloody tears as the initial symptom. Methods: Retrospective series of case studies. The clinical data and follow-up data of 27 cases of bloody tears as the first symptom in Lacrimal Center of Ophthalmology, the Third Medical Center of Chinese PLA General Hospital from June 2015 to December 2018 were reviewed. The clinical feature, specific cause, diagnosis, treatment and prognosis of these cases were evaluated. Results: A total of 27 cases were collected in this study. The patients were 10 males (37.0%) and 17 females (63.0%), including 21 adults (≥ 18 years old, 77.8%) and 6 minors (<18 years old, 22.2%). There were 22 monocular cases (81.5%) and 5 binocular cases (18.5%). Five cases (18.5%) were bleeding from the eye and other parts of the body, and 22 cases (81.5%) were bleeding only from the eye. There were 19 cases (70.4%) with hematic epiphora and secretions from the punctum, 3 cases (11.1%) with blood-stained tears, and 7 cases (25.9%) with blood-like tears. With regard to etiology, 6 cases (22.2%) were combined with systemic lesions, one of which was granulomatosis with polyangiitis and five of which (<18 years old) were idiopathic bloody tears. Twenty-one cases (77.8%) were local lesions, including 18 cases only involving the lacrimal system, 2 cases only involving the ocular surface, and 1 case involving both the lacrimal system and the ocular surface. Among the 21 cases with local lesions, 5 cases were induced by foreign body, 6 cases were induced by simple inflammation, and 10 cases were induced by tumor including 1 case with conjunctival benign tumor and 9 cases with tumor of the lacrimal system (5 with malignant tumor and 4 with benign tumor). Patients with idiopathic bloody tears received psychological and medical treatment, and interictal discharge was lengthened. One case of granulomatosis with polyangiitis was treated by trans-nasal endoscopic dacryocystorhinostomy. With the recurrence of granulomatosis and polyangiitis, bloody tears recurred after surgery. One patient with conjunctival hemangioma was untreated. Lesions in the lacrimal duct system were removed and dacryocystorhinostomy was performed. In this study, 2 patients (1 with small cell neuroendocrine carcinoma and 1 with adenoid cystic adenocarcinoma) died and the other had a good prognosis. Conclusions: Among the cases of bloody tears, adults and local lesions are more common. Most of the lesions are located in the lacrimal system and are tumors. The main treatment is to remove the lesions, and if necessary, to expand the resection and reconstruct the lacrimal duct. Idiopathic bloody tears occur in minors, who are gave psychotherapy and necessary medical treatment. (Chin J Ophthalmol, 2020, 56: 53-58).

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

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. 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.

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.

Use of an image-guided navigation system for routine endonasal endoscopic dacryocystorhinostomy.

OBJECTIVE: This study aimed to evaluate the results of routine endonasal endoscopic dacryocystorhinostomy combined with computed tomography guided navigation in patients with nasolacrimal duct obstruction. METHOD: This was a retrospective study of all patients with lacrimal drainage obstruction undergoing stereotactic endoscopic dacryocystorhinostomy between 1st January 2016 and 1st April 2018. Computed tomography dacryocystography was used for intra-operative navigation. Patients with a presaccal obstruction site location were excluded from the study. RESULTS: Endoscopic dacryocystorhinostomy with computed tomography guided navigation was successfully performed in all 17 cases without complications. Early post-operative dislocation of the inserted bicanalicular silicone stent occurred in two patients. Two other patients developed post-operative bacterial infection within the lacrimal sac. Otherwise, the silicone tube was removed three months after surgery, and after further follow up of 8 weeks, 94 per cent of the study population reported complete remission of epiphora. CONCLUSION: The use of computed tomography guidance in routine endoscopic dacryocystorhinostomy enhanced safety for the patient and avoided unnecessary damage of bone and mucosa surrounding the lacrimal drainage system. Therefore, routine endoscopic dacryocystorhinostomy with additional stereotactic guidance by computed tomography navigation can contribute to high success rates with endoscopic dacryocystorhinostomy.

[Pediatric acute dacryocystitis due to frontoethmoidal mucocele]. / Akute Dakryozystitis im Kindesalter bei frontoethmoidaler Mukozele.

BACKGROUND: Pediatric acute dacryocystitis typically develops due to persistence of Hasner's membrane. Pediatric paranasal mucoceles are rare entities. In contrast, chronic dacryocystitis in cases of congenital dacryostenosis is one of the most frequent pediatric ophthalmologic issues. METHODS: The case report of a 10-year-old girl suffering acute dacryocystitis is presented. RESULTS: The area around the left lacrimal sac showed a painful swelling with edema and hyperemia. Systemic and local antibiotic therapy resulted in only slight improvement. Dacryoendoscopy detected acute dacryocystitis with significant stenosis of the nasolacrimal duct. The nasolacrimal duct was widened dacryoendoscopically and autostable bicanalicular nasolacrimal intubation was performed. Nevertheless, the lacrimal ducts were blocked subtotally and a widening of the ethmoid on the left side was shown by rhinoscopy. Magnetic resonance imaging confirmed a frontoethmoidal mucocele which was treated by marsupialization. During the 24-month follow-up there was no recurrence of acute dacryocystitis. There were no signs of sinusitis. CONCLUSION: Paranasal mucoceles, e. g., ethmoidal mucoceles, can compress the lacrimal pathways and cause acute lacrimal inflammation in childhood. Paranasal mucoceles should thus be excluded in cases of unclear masses in the lacrimal region.

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.
