Doctor's Notes on Retinal Detachment
Retinal detachment is a condition where the retina, which is normally lies flush with the inside back wall of the eye, detaches and no longer lies flush. Signs and symptoms of retinal detachment are blurred, dim and/or distorted vision. Some individuals describe a cloud or curtain-like obstruction of vision. Usually there is no pain associated with retinal detachment unless it is associated with inflammation or elevated eye pressure. Some patients may experience floaters and flashing lights prior to retinal detachment. A physician can observe retinal tears and detachments with special ophthalmoscopy; the outside of the eye looks typically normal.
The most common cause of retinal detachment is when the vitreous gel inside the eye contracts and pulls or tears the retina away from its flush position against the eye wall. Gel retraction can occur over time or suddenly after trauma. Other conditions associated with an increased risk of retinal detachment include diabetes, sickle cell disease, scar tissue, high myopia, retinal degeneration, inflammatory disorders, autoimmune diseases and certain cancers.

Diabetes (Type 1 and Type 2)What causes diabetes, what tests diagnose it, and what is a good diabetic diet? Learn the signs of being diabetic, the treatments, and the differences between type 1 vs. type 2 diabetes. Type 1 diabetes (insulin dependent) can be caused by heredity, environmental factors, or ethnicity. Type 2 diabetes (non-insulin dependent) can be caused by high blood pressure, high lipid levels, high-fat diet, high alcohol intake, sedentary lifestyle, obesity, ethnicity, or age.
Diabetic Eye DiseaseDiabetes is one of the leading causes of blindness in the US and worldwide. Diabetic eye disease is a complication from diabetes. Types of diabetic eye disease include blindness, background diabetic retinopathy, nonproliferative diabetic retinopathy, diabetic macular edema, proliferative diabetic retinopathy, cataracts, and glaucoma. Symptoms of diabetic retinopathy includes blurry or hazy vision, difficulty focusing, and night glare from oncoming lights. Causes of diabetic eye disease occur over time due to hypoglycemia (high blood sugar) and other abnormalities in metabolism found in people with diabetes. Treatment for diabetes eye problems depends on the type of eye problem. Medication and surgery for diabetes eye problems may be necessary in addition to lifestyle changes such as eating a healthy diet, exercise, quitting smoking.
Eye FloatersEye floaters are often described as black spots or squiggly strands in a patient's field of vision. Floaters may be caused by a spontaneous vitreous separation, a retinal hole or tear, foreign bodies, macular degeneration, or postoperative matter. Treatment of floaters depends upon the underlying cause.
Sickle Cell DiseaseSickle cell disease is a form of anemia and is the most common hereditary blood disorders with symptoms of dehydration, fever, and cold exposure. In sickle cell disease, the red blood cells are shaped abnormally, and have a "sickle" shape.
UltrasoundUltrasound (sonography, Doppler study) is a non-invasive diagnostic medical procedure performed to exam the internal organs and tissues of the body. There are several types of ultrasound, including 2D, 3D and 4D. An abdominal ultrasound is commonly used to examine the fetus during pregnancy, while a transvaginal ultrasound may be used to assess non-pregnancy symptoms
