As part of a comprehensive eye exam with our Henderson eye doctor, Joseph Eng, OD, you will be screened for any signs of common eye diseases. By providing you an overview of them, we hope to keep you informed so that you will be aware of the symptoms of them. But even more importantly, since these diseases can often begin and progress without any symptoms or pain, we want to impress upon you the importance of coming in for your yearly eye exam.
Glaucoma is caused by an excess of internal air pressure inside your eye. It can lead to damaging your optic nerve. If left unaddressed, it can even cause permanent vision loss. Most at risk for glaucoma are people over 40, those with a family history, and anyone with diabetes. Other factors that make you more susceptible to glaucoma are taking Prednisone and other steroids and family heritage that is Irish, Russian, Hispanic, African-American, Japanese, Scandinavian, or Inuit. Symptoms may not be present, but if you notice a loss of peripheral vision, sudden eye pain, headaches, blurry vision, or halos appearing around light, you should call and schedule an immediate appointment with our Henderson eye doctor.
Cataracts refer to a clouding of your eye lens deriving from buildups of protein. Heredity and age tend to be the greatest risk factors, but sometimes it can result from exposure to toxins or certain drugs, or due to a traumatic eye injury. Symptoms include blurry vision, clouded vision, difficulties driving at night, double vision, a sudden change in your corrective lens needs, and progressive nearsightedness where you no longer need reading glasses. Although cataracts progress slowly, you should be examined by our Henderson eye doctor if you experience any of the mentioned signs.
Macular degeneration and diabetic retinopathy are usually applicable only to certain people. With macular degeneration, the most common cause of vision loss in people over 60, there is deterioration in the macula, which is in the center of your retina. It generally does not cause complete vision loss but as it advances, it can cause significant challenges to your vision. It cannot be cured, but it can be treated and the progression slowed. Diabetic retinopathy is a complication that can occur in those who have diabetes. It can cause damage to the blood vessels in your eyes. Symptoms usually do not present until the disease becomes severe, but include loss of central vision when driving or reading, difficulty seeing color, and blurred vision. If left untreated, it can cause retinal detachment and even blindness. If you have diabetes- or are at high risk for it- it is essential to be examined yearly by our Henderson eye doctor.
