RESUMEN
ABSTRACT Objective: To develop and examine the usability of a mobile application aimed at improving knowledge about ocular surface tumors among medical students, general practitioners and ophthalmologists. Methods: A cross-sectional quantitative study was carried out by a multidisciplinary team and developed in three stages: administration of a specific questionnaire to medical students, assessing the demand for the application, creation and development of the application in collaboration with the Technological Innovation Laboratory of Centro Universitário Christus and usability assessment. General practitioners and ophthalmologists were selected to answer the System Usability Scale questionnaire. Data were exported into the Statistical Package for the Social Sciences, version 20.0 Windows, for quantitative analysis. Results: The OncoEye application was developed for the iOS and the Android platforms and included four main menus: Glossary, Patients, Referrals and Queries. Most students (89.9%) considered the development of the application important for wider access to information about the topic. Most students (39.9%) were able to recognize ocular lesions and 26.1% could distinguish between benign and malignant conditions. System Usability Scale questionnaire responses revealed good usability, with an average score of 92.65. Users (100%) described the application as user-friendly and well- integrated. Conclusion: An innovative application for ocular surface tumors was created and developed. The application achieved good levels of acceptance and was described as user-friendly by users.
RESUMO Objetivo: Desenvolver e avaliar a usabilidade de um aplicativo para dispositivos móveis que aprimore o conhecimento de estudantes de medicina e de médicos sobre tumores da superfície ocular. Métodos: Foi realizado estudo transversal e quantitativo por uma equipe multiprofissional, consistindo em três etapas: realização de um questionário específico com estudantes de medicina, avaliando a necessidade de elaboração do aplicativo; criação e desenvolvimento do aplicativo pelo Laboratório de Inovação Tecnológica do Centro Universitário Christus e avaliação de usabilidade. Médicos generalistas e oftalmologistas foram selecionados para responder ao questionário System Usability Scale. Os dados foram exportados para o programa Statistical Package for the Social Sciences, versão 20.0, para Windows para análise quantitativa. Resultados: O aplicativo OncoEye foi desenvolvido com quatro menus principais: Glossário, Pacientes, Encaminhamento e Perguntas. Dentre os estudantes, 89,9% consideraram o desenvolvimento do aplicativo importante para orientação sobre o tema, 39,9% souberam reconhecer lesão ocular, e 26,1% puderam diferenciar lesão ocular maligna ou benigna. As respostas dos usuários à ferramenta System Usability Scale demonstraram boa usabilidade, com pontuação média de 92,65 (87,74 a 97,55). Todos os usuários consideraram o aplicativo de fácil manuseio e bem integrado. Conclusão: Um aplicativo inovador para tumores da superfície ocular foi criado e desenvolvido, apresentando boa aceitação e fácil manuseio pelos usuários.

INTRODUCCIÓN: El carcinoma adenoide quístico (CAQ) es conocido por su lento crecimiento, su tendencia a la recurrencia local y al desarrollo de metástasis a distancia incluso décadas después del diagnóstico inicial, y a pesar de terapias agresivas. OBJETIVO: Presentar el caso de una paciente con CAQ de la glándula lagrimal, tumor muy infrecuente que representa casi el 10% de las lesiones orbitarias ocupantes de espacio. De éstas el 20-30% son de origen epitelial, de las cuales el 55% son lesiones benignas y el 45% malignas. El CAQ es el más común de los tumores epiteliales malignos de la glándula lagrimal (65%). CASO CLÍNICO: Presentamos el caso clínico de una paciente con CAQ de glándula lacrimal diagnosticado de forma incidental tras la realización de TAC desde la consulta de psiquiatría. RESULTADOS Y CONCLUSIONES: El síntoma de presentación más frecuente suele ser la proptosis, acompañada o no de dolor, aunque también puede presentarse como ptosis mecánica, reducción de visión y diplopía. La cirugía radical no ha demostrado mejorar la supervivencia o reducir la recurrencia local en comparación con un abordaje quirúrgico, más conservador en pacientes con tumores de menor tamaño y sin afectación ósea. Las mayores tasas de supervivencia se han conseguido, en pacientes tratados con quimioterapia, con quimioterapia citorreductiva intra-arterial seguida de exenteración orbital y radioterapia.
INTRODUCTION:The adenoid cystic carcinoma (ACC) is known for its slow growth, a tendency to local recurrence and the development of distant metastases even decades after the initial diagnosis, and despite aggressive therapies. AIM:We present the case of a patient with a lacrimal gland tumor. They are very rare tumors that represent almost 10% of space-occupying orbital lesions, of which 20-30% are of epithelial origin, of these, 55% are benign and 45% are malignant. The ACC is the most common malignant epithelial tumor (65%). CASE REPORT :We present the clinical case of a patient with ACC of the lacrimal gland incidentally diagnosed after performing a CT scan from the psychiatric office. RESULTS AND CONCLUSIONS:The most frequent presentation symptom is usually proptosis, accompanied or not accompanied by pain, although it can also occur as mechanical ptosis, vision reduction, and diplopia. Radical surgery has not been shown to improve survival or reduce local recurrence compared to a more conservative surgical approach in patients with smaller tumors and without bone involvement. The highest survival rates have been achieved, in patients treated with chemotherapy, with intra-arterial cytoreductors (IACC) followed by orbital exenteration and radiotherapy.

Here we describe a rare case of a benign tumor in the lacrimal gland of a healthy 4-year-old girl. Mild proptosis was the only abnormality observed on clinical examination. Magnetic resonance imaging of the right orbit revealed an oval, solid, well-circumscribed, homogeneous mass extending from the lacrimal gland and measuring 2.5 × 2.3 × 1.7 cm without any evidence of invasion into adjacent bones. The lesion was surgically excised and histological analyses defined the diagnosis of oncocytoma of the lacrimal gland. Although rare, oncocytoma should be included in the differential diagnosis of lacrimal gland tumors.

Resumo Nós descrevemos um raro caso de tumor benigno na glândula lacrimal em uma criança sadia de 4 anos de idade. Clinicamente, a paciente apresentava apenas uma discreta proptose. A ressonância nuclear magnética (RNM) de órbita direita revelou a presença de uma massa oval, sólida, bem-circunscrita, homogênea, se extendendo a partir da glândula lacrimal, medindo 2,5 cm x 2,3 cm x 1,7 cm, sem nenhum sinal evidente de invasão a estrutura óssea adjacente. A lesão foi cirurgicamente removida e analizada histopatologicamente, sendo estabelecido o diagnóstico de oncocitoma de glândula lacrimal. Apesar de raro, o oncocitoma deve ser incluído no diagnóstico diferencial de qualquer tumor originado da glândula lacrimal.

A 30-month-old boy presented to a Haitian emergency department with proptosis, periorbital edema, and progressive blindness. Bedside ultrasound examination revealed bilateral ocular masses with dense calcifications pathognomonic for retinoblastoma. This case illustrates the diagnostic utility of bedside ultrasound for an advanced case of retinoblastoma in a resource-poor setting. Ocular ultrasound technique is also reviewed.

Thirty-seven patients with retinoblastoma were evaluated prospectively by clinical examination, lumbar puncture, and CT. Eight (22%) of the 37 were found to have meningeal dissemination. The tumor was bilateral in three patients. Two cases showed no CT signs of local recurrence. Headache, nausea/vomiting, and restlessness were the most common symptoms. CT scans in these patients showed diffuse meningeal contrast enhancement, nodular masses, ependymal-subependymal enhancement, and ventricular dilatation. Our series of eight patients with meningeal spread illustrates a considerable range of dissemination patterns referable to retinoblastoma. One case illustrated the CT finding of multiple epidural metastases.
