- GlaucomaVein occlusions are blockages of the central (main) vein or one of its four branches draining the retina. Although there are many causes of vein occlusions, the most common identified risk factors include advanced age, high blood pressure, diabetes and glaucoma.
- Macular DegenerationHighly effective in imaging the layer beneath the retina, the choroid, which may be important in some variants of macular degeneration, and choroidal disorders affecting the retina.
- Laser Eye SurgeryThere are three kinds of retinal detachments. The most common form, described above, occurs when fluid leaks into the retina; people who are nearsighted or who have had an injury or eye surgery are most susceptible. Less frequently, friction between the retina and vitreous or scar tissue pulls the retina loose, something that occurs most often in patients with diabetes. Third, disease-related swelling or bleeding under the retina can push it away from the eye wall.
- CataractsHigh resolution sonogram that is utilized to evaluate in cases of intraocular bleeding, trauma, tumors, and when the view of the retina is obscured by a corneal scar or extremely dense cataract.
- Eye ExamAs diabetic retinopathy advances, the normal retinal vessels close (retinal ischemia). The retina now is not receiving adequate blood nourishment. In an effort to compensate for the lack of normal circulation, the retina grows new, abnormal blood vessels (proliferative diabetic retinopathy). The abnormal vessels are not helpful and can lead to severe loss of vision with bleeding, scar tissue growth, and retinal detachment. The abnormal blood vessel growth can be halted with timely laser treatment or surgical removal (vitrectomy surgery). Just like macular edema, you can have severe abnormal blood vessel growth in your eye and still have excellent vision. It is important for diabetics to have at least a yearly eye exam to monitor for significant retinopathy. Early and aggressive treatment of diabetic retinopathy is extremely successful in preventing severe vision loss. In order to maximize the health of your retinal circulation, as well as the circulation to the heart and kidneys diabetics should lower their vascular risk factors: don't smoke, control hypertension, exercise, lower your cholesterol, eat a low fat diet and follow your family doctor's instructions.
- Diabetes Care
- Diabetic RetinopathyDiabetic retinopathy is a complication of diabetes mellitus. Diabetes damages the normal circulation of the body. That is why diabetics have problems with the circulation to their legs, kidneys, heart, brain and eyes. Initially, diabetes causes the retinal vessels to leak resulting in retinal swelling (macular edema) and vision loss. The leaking vessels can be sealed with a laser to resolve the swelling and prevent further vison loss. Significant macular edema may be present even if your vision is excellent.
