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 [...]

Highlights

The diagnosis of Ocular surface tumors (OST) can be based on medical history and findings of specialized eye exams.[1]The most common malignant tumors of the cornea and conjunctiva are ocular surface squamous neoplasia, conjunctival melanoma and conjunctival lymphoma.[2]Several factors contribute to OST development, including exposure to ultraviolet radiation, advanced age, male gender and primary or acquired immunodeficiency.[3]
The usability of the mobile application was examined using a validated questionnaire administered to general practitioners and ophthalmologists
The potential availability of an OST-related application appealed to third-year Unichristus medical students, as 89.9% considered the development of an application containing information about ocular surface tumors to be important, even though this is a topic reserved for specialists (Table 1)

Summary

Introduction

The diagnosis of OST can be based on medical history and findings of specialized eye exams.[1]The most common malignant tumors of the cornea and conjunctiva are ocular surface squamous neoplasia, conjunctival melanoma and conjunctival lymphoma.[2]Several factors contribute to OST development, including exposure to ultraviolet radiation, advanced age, male gender and primary or acquired immunodeficiency.[3]. In this context, OST diagnosis can be extremely challenging, since not all physicians are familiar with these lesions, in cases with atypical clinical presentations. Many alternative tools and exams can be used to assist OST diagnosis and management.[3]
