| Resumo: | 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. |
