Resumo: | Objective: Develop methods to improve eye care, with a new model and teaching methodology for the study of direct ophthalmoscopy and development of new technologies for data and image analysis. Method: After studying the irregular distribution of ophthalmologists in countries like Brazil and Portugal, a questionnaire was carried out with non-ophthalmologists to assess the level of confidence in the direct ophthalmoscopy exam. Next, the human eye model was made from physical calculations using cardboard paper with a black background, acrylic sphere, and plaster. The model was applied in the teaching of direct ophthalmoscopy and red reflex test. New image and data analysis technologies have been developed. An algorithm was developed for the evaluation of macula edema in fundus color photography and an image analysis and control program for toxoplasmosis chorioretinitis. Results: The results of the questionnaire showed that doctors feel less confident in the diagnosis through direct ophthalmoscopy. The model proved to be effective in teaching direct ophthalmoscopy and red reflex test. Its versatility allowed it to be used for teaching veterinary medicine students. The developed algorithm proved to be useful in the detection of edema in fundus color photography of diabetic patients and the image analysis program proved to be useful for the monitoring of patients with toxoplasmosis uveitis. Conclusion: Searching for alternatives to improve the population's ophthalmic service, a simple and low-cost model of the human eye was developed to be used in the teaching of direct ophthalmoscopy and red reflex test, which enabled the teaching and training of this technique, including adapted for the teaching of direct ophthalmoscopy in veterinary medicine students. This can be a teaching method easily adopted by any educational institution due to its low cost and effectiveness. The development of new data and image analysis technologies has proven to be useful alternatives for the diagnosis and monitoring of ophthalmic diseases in situations where we do not have adequate access to eye careObjective: Develop methods to improve eye care, with a new model and teaching methodology for the study of direct ophthalmoscopy and development of new technologies for data and image analysis.
