Common Eye Disorders and Diseases
People from all over the world have journeyed here to watch this famous geyser. Old Faithful is one of nearly geysers in Yellowstone and one of six that park rangers currently predict. It is uncommon to be able to predict geyser eruptions with regularity and Old Faithful has lived up to its name, only lengthening the time between eruptions by about 30 minutes in the last 30 years.
Back to Health A to Z. Diabetic retinopathy is a complication of diabetes , caused by high blood sugar levels damaging the back of the eye retina. It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight. The retina is the light-sensitive layer of cells at the back of the eye that converts light into electrical signals.
