Automatic Grading of Retinal Blood Vessel in Deep Retinal Image Diagnosis
AbstractAutomatic grading of retinal blood vessels from fundus image can be a useful tool for diagnosis, planning and treatment of eye. Automatic diagnosis of retinal images for early detection of glaucoma, stroke, and blindness is emerging in intelligent health care system. The method primarily depends on various abnormal signs, such as area of hard exudates, area of blood vessels, bifurcation points, texture, and entropies. The development of an automated screening system based on vessel width, tortuosity, and vessel branching are also used for grading. However, the automated method that directly can come to a decision b...

How Good is Photoscreening For Young Children ’ s Vision Problems?
This study showed that not only was smartphone photoscreening feasible, but was quite good at screening for potential vision problems. Smartphone photoscreening has the advantages of being more ubiquitously available and thus children in almost any location can be screened. A study of photoscreening using a handheld digital photoscreener in primary care offices validated the technology showing an overall referral rate of 10% to an ophthalmologist with suspected astigmatism, anisometropia and strabismus being the most common reasons. The overall positive predictive rate was 0.60. “…[O]ver 60% of children referre...
