Some children have diabetes but developing diabetes is much more common later in life. Diabetes can cause complications which affect different parts of your body, including your eye(s). The two main types of diabetes mellitus are known as Type 1 and Type 2 diabetes.
This type of diabetes commonly occurs before the age of 30 and is the result of the body producing little or no insulin. Type 1 diabetes is primarily controlled by insulin injections so it is sometimes called insulin dependent diabetes.
This type of diabetes commonly occurs after the age of 40. In this type of diabetes the body does produce some insulin, but the amount is either not sufficient or the body is not able to make proper use of it. Type 2 diabetes is generally controlled by diet, exercise and/or tablets. Although some people in this group will use insulin injections it is sometimes referred to as non-insulin dependant diabetes.
