A Catarata ? uma patologia dos olhos que consiste na opacidade parcial ou total do cristalino (lente natural do olho) ou de sua c?psula. Pode ser desencadeada por v?rios fatores, como traumatismo, idade, diabetes mellitus, uso de medicamentos, entre outros. Sabe-se que o atendimento por oftalmologistas no Brasil nas ?reas rurais e mais pobres ? inferior ao necess?rio e muitos pacientes com doen?as trat?veis como a Catarata ficam sem diagn?stico e consequentemente sem tratamento. Neste contexto, esse projeto tem como proposta o desenvolvimento do OPTICA, um sistema de tele-oftalmologia que utiliza smartphones para detec??o de urg?ncias oftalmol?gicas, disponibilizando um aux?lio ao diagn?stico a Catarata utilizando sistemas inteligentes e t?cnicas de processamento de imagens. As imagens ser?o capturadas por um celular com uma lente especial acoplada a c?mera e juntamente com um question?rio com informa??es do paciente ser?o transmitidos de forma segura via a plataforma Sana Mobile (sana.mit.edu) para uma central online de laudos que disp?e de um programa inteligente de auxilio ao diagn?stico a Catarata e de m?dicos oftalmologistas que ir?o analisar as informa??es e emitir o laudo do paciente. Desta forma, o OPTICA permite levar atendendimento oftalmol?gico a popula??o menos favorecida e em ?reas remotas , melhorando a triagem de pacientes graves e aumentando o acesso ao diagn?stico e tratamento. / The increasing in world population, with higher proportion of elderly, leads to an increase in the number of individuals with vision loss and cataracts are one of the leading causes of blindness worldwide. Cataract is an eye disease that is the partial or total opacity of the crystalline lens (natural lens of the eye) or its capsule. It can be triggered by several factors such as trauma, age, diabetes mellitus, and medications, among others. It is known that the attendance by ophthalmologists in rural and poor areas in Brazil is less than needed and many patients with treatable diseases such as cataracts are undiagnosed and therefore untreated. In this context, this project presents the development of OPTICA, a system of teleophthalmology using smartphones for ophthalmic emergencies detection, providing a diagnostic aid for cataract using specialists systems and image processing techniques. The images are captured by a cellphone camera and along with a questionnaire filled with patient information are transmitted securely via the platform Mobile SANA to a online server that has an intelligent system available to assist in the diagnosis of cataract and provides ophthalmologists who analyze the information and write back the patient?s report. Thus, the OPTICA provides eye care to the poorest and least favored population, improving the screening of critically ill patients and increasing access to diagnosis and treatment.
