Review of Retinal Microaneurysm Detection Methods for Automated Diagnosis of Diabetic Retinopathy

Microaneurysm in the retina is one of the early signs of diabetic retinopathy. The recognition of Microaneurysms is an essential and the most challenging tasks for reliable automatic detection and diagnosis of diabetic retinopathy. This helps ophthalmologist to detect the emergence of its early symptoms and determine the next action step for the patient. A number of studies have been investigated on retinal FUNDUS images for diabetic retinopathy. This paper deals with the recently introduced methods for analyzing the microaneurysms detection, available for automated diagnosis. Although many algorithms have been developed, the accurate detection of microaneurysm in color retinal images is still a challenging problem. Automating this task, which is currently performed manually, would bring more objectivity and reproducibility.
