A predictive screening tool to detect diabetic retinopathy or macular edema

This mobile app is a medical calculator indicating the likelihood that a diabetic patient suspected of having severe, very severe or proliferating retinopathy or macular edema really has it.This mobile app is a medical calculator indicating the likelihood that a diabetic patient suspected of having severe, very severe or proliferating retinopathy or macular edema really has it.

To calculate this probability we need to know the following patient parameters: HbA1c (%), foveal thickness (µm) and visual acuity (units).

The mobile app will calculate a score based on the risk according to the above parameters. Patients will have a greater risk for these disorders if they have a high HbA1c concentration, a greater foveal thickness and a lower visual acuity. From the points given the patient will be classified in a particular risk group, which will have an associated likelihood of having at least one of these disorders.

If a patient is found to be in the high or very high risk group we should refer that patient to the specialist services. On the other hand, if the risk is found to be medium or low, the patient can be followed by the primary care physician.
