    Diabetes is a group of metabolic diseases in which the person has very high blood sugar. This is either because the production of insulin is inadequate or because the body cells do not properly respond to insulin. Obesity, on the other hand, is a health condition whereby excess body fat has accumulated to an extent where it has a negative effect on health. This leads to reduced life expectancy and increased health problems. Diabetes and obesity are closely tied as doctors highly link diabetes to people’s weight problem. This study focuses on the relationship between obesity and diabetes and the care for patients suffering from these conditions.

    The standard tests that an ophthalmologist will give a new and continuing patient are checking color vision, visual acuity which is when the patient reads a word or picture chart off the wall to check the smallest letters or pictures to be read, and a refraction test to check an existing eyeglass prescription. If retinal detachment is suspected they will do a fluorescein angiography to check the blood flow in the retina. This is done by using a special dye and a camera and a scope called an ophthalmoscopy. The ophthalmologist will also most likely do a slit-lamp examination to check the structures of the front of the eye and tonometry which checks the pressure inside the eye. An ultrasound of the eye can determine how severe a retinal detachment is and what treatment procedures can be done to correct it if possible (Frazier
