The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
Diabetic retinopathy is considered as the disease of eye associated with diabetes. It is caused by the blood vesselâs changes in the retina. After these blood vessels get damaged, the leaking of blood may occur resulting in the growth of fragile new vessels. These changes of cell damage leads to the impairment of vision. These changes can result in blurring of the vision, hemorrhage into the eye, or, if untreated, retinal detachment can also take place. Microaneurysms, Retinal edema and hard exudates, Cotton-wool spots, Dot and blot hemorrhages, Macular edema are some of the related causes of Diabetic retinopathy. Fluorescein angiography, Optical coherence tomography scanning and B-scan ultrasonography are the preferred diagnosis for Diabetic retinopathy. This is further classified as mild, moderate and severe depending on the presence of various deciding factors. Maintaining a regular exercise and a healthy diet, keeping blood sugar within the normal limits and the prescribed medications can be opted in the day to day life to prevent diabetic retinopathy.
