Sažetak
Diabetes mellitus is the most frequent endocrine disease in developed countries estimated to have affected 366 million people worldwide and is expected to nearly double by 2030 owing to an increase in obesity, life span extension, and better detection of the disease. It has been well established that in patients with diabetes a transient visual disturbances may occur, usually caused by changes in their refraction. There is a little doubt that the transient refraction changes are associated with variations in blood glucose levels but the nature of the relationship between the two parameters still remains unresolved. Some authors consider that increased blood sugar leads in to a myopic shift and others that the change is in hyperopic direction. The underlying mechanism governing the relationship between plasma glucose concentration and refractive error is not fully understood. There is no clear answer as to whether the refractive changes seen are due simply to changes in refractive index of the cornea, aqueous humour or lens or whether swelling of the lens occurs, causing changes to its curvature, position or size. Ultimately, it would be helpful to all involved in refraction to understand how blood glucose concentration could potentially affect the ocular parameters that contribute to the refractive power of the eye. A better understanding of this problem will allow to advise diabetics on expected visual signs and symptoms during period of altering diabetic metabolic control, such as blurred vision at distance and near or fluctuations in vision.
