Maintaining good vision depends on keeping your eyes in tip-top shape, which necessitates having an annual comprehensive eye examination with an eye care professional such as our optometrist in San Antonio at The Eyeglass Shop. The comprehensive exam will measure your visual acuity and then our doctor will check for and prescribe any needed vision corrections. During the dilated portion of the exam our doctor will look at the structure of your eyes to check for any abnormalities. The exam is critical for the detection and diagnosis of any eye diseases many of which have no symptoms in the early stages when treatment options are more effective and less invasive.
One such serious eye disease is diabetic retinopathy, which is usually found among patients that suffer from diabetes, an inability of the body to control the amount of sugar in the blood. Diabetic retinopathy is a disorder where abnormalities develop in the blood vessels that feed the light sensitive retina. These abnormal blood vessels may start to leak affecting vision and eventually leading to a loss of vision. Diabetic retinopathy is the leading cause of blindness in adults under the age of 65 and a major cause of vision loss for seniors. A diabetic eye exam from our optometrist in San Antonio is the only way to detect the disorder before vision is seriously impacted. During a dilated eye exam our doctor will look for signs of abnormal blood vessels leading to the retina, swelling or blood in the retina or surrounding tissues including the vitreous, the growth of new blood vessels, and retinal detachment.
A diabetic eye exam may also include fluorecein angiography where our doctor will take pictures of your eyes and retina during the dilated exam and then inject a dye in your arm and take another set of photos as the dye travels through the blood vessels to check for any closed, broken vessels or leaking fluid. Another test is an optical coherence tomography, which shows cross sections of the retina to determine if fluid has leaked into the retinal tissue. Treatment for diabetic retinopathy depends on the severity of the case. Our optometrist in San Antonio will work with the patient’s endocrinologist to better control the underlying diabetes. In more severe cases laser surgery to stop leakages and shrink abnormal vessels may be used. Traditional surgery is also an option in some severe cases. The best treatment is early detection through an annual comprehensive eye exam, so call our office for an appointment.
