Q: What is a cataract?
A: A cataract is a clouding of the lens of the eye. In early stages new glasses may be all that are needed to correct the vision. As the cataract grows it may require surgery. With advanced surgical techniques not requiring any stitches, Dr. Donzis can remove the cataract and replace it with a clear plastic lens called an intraocular implant which will restore vision.
Q: What is macular degeneration?
A: Macular degeneration is a disease that affects the central portion of the retina. It is most often associated with aging and causes a distortion of the central vision that often is first noticed by difficulty reading. The disease typically progresses slowly and peripheral vision is not usually affected. Dr. Donzis is a firm believer in preventative therapy and recommends anti-oxidant vitamins and ultraviolet protection eyewear to his patients at risk for this disease.
Q: What is glaucoma?
A: Glaucoma is a disease caused by increased pressure in the eye. Unless detected and controlled this disease can lead to blindness. The pressure pushes on the optic nerve causing damage to the nerve cells. Normally, the disease progresses very slowly without any noticeable symptoms until the advanced stages. Early detection and treatment, usually with eyedrops alone, is successful in preventing any loss of vision in the majority of patients.
Q: Can high blood pressure or diabetes affect the eye?
A: Many systemic diseases lead to changes in the eye. High blood pressure and diabetes both can affect the blood vessels in the retina. Diabetes, in particular, is one of the leading causes of blindness in the world. Diabetes is associated with retinopathy that can permanently affect vision. Fortunately, a thorough examination can detect these changes long before they have a chance to permanently affect vision. Laser treatment has dramatically improved the prognosis for patients with diabetic retinopathy.
