Diabetes and diabetic retinopathy
Diabetes mellitus is a condition which impairs the body's ability to use and store sugar. Diabetes can cause serious changes in the blood vessels throughout the body, including the eye and kidney. It can cause complications with ulcers in the feet. Diabetic retinopathy can start without symptoms and can get worse over time. If you are a diabetic, you can protect and preserve your eyesight by keeping your blood sugar under control, learning about your eyes, having eye exams regularly and following your doctor's treatment plan.

Macular degeneration
Macular degeneration is the leading cause of loss of vision among people over the age of 65. Sometimes the disease can affect patients who are younger. It is a process of wear and tear in the macula, which is the center part of the vision in the eye. Usually it affects both eyes with either gradual or abrupt loss of vision. It can affect your ability to read, drive and see fine details. Since side vision is rarely affected by macular degeneration, the disease rarely leads to total blindness. It is also not caused by overusing your eyes. There are two types of macular degeneration - the dry type, which causes a gradual loss of vision, and the wet type, which causes a sudden loss of vision.

Retinal detachment
Retinal detachments affect about one in 10,000 people in the United States. It typically happens to patients who are nearsighted or have a family history of retinal detachments. Retinal detachments can also happen after cataract surgery. Sometimes a hard blow to the eye can cause retinal detachment. In some cases, it is a hereditary condition and occurs in children and infants. If the detachment is not diagnosed and treated it can lead to visual impairment and even complete loss of vision.

Macular hole
The macula, which is a specialized area of the retina, is responsible for clear, detailed vision. A macular hole is an abnormal opening that forms in the center of the macula over weeks to months. Macular holes in most cases are caused by either the vitreous jelly within the eye pulling on the macula until it tears or sometimes scar tissue on top of the retina causes a macular hole.

Retinal vein occlusions
A blockage or occlusion in the vein in the retina can occur in either a branch of the main vein or in the main vein itself. In the eye there is an artery that brings blood to the eye, and there is a vein that takes blood away from the eye. The artery lies on top of the vein. In some patients, the artery on top can become thicker and heavier due to high blood pressure and it can press on the vein that is running underneath it. This will cause leakage of blood and fluid into the retina.
