  • Macular Degeneration
    DRIVEWELL Driving When You Have Macular Degeneration You have been a safe driver for years. For you, driving means freedom and control. As you get older, changes in your physical and mental health can affect how safely you drive. Macular degeneration (also known as age-related macular degeneration) damages the macula, a spot near the center of the retina (light-sensitive inner lining of the eyeball). It is a common eye problem among older drivers that makes it hard to drive safely. Age-related macular degeneration is the leading cause of new cases of blindness in people 65 and older. If you have macular degeneration, you may not notice any signs in the early stages. You may not know you have this condition until you lose your peripheral vision (what you see out of the corner of your eyes). In time it will affect your central vision, causing a dark or empty area in the center of your vision. How Can Macular Degeneration Affect the Way I Drive? • Your central vision may be dull and blurry. This can lead to loss of sharp vision. • You may not see the road, street signs, lane markers, and even people and bicyclists in the road. • You may need more bright light to see up close. • Colors may look less vivid or bright. • You may have trouble when you go from bright light to low light. • You may not be able to recognize people’s faces. What Should I Do if I Have Any of These Signs? As soon as you notice any of these warning signs: • Tell your family or someone close to you, especially if you have a family history of macular degeneration or have changes in your central vision.

  • Detached and Torn Retina Retinal Detachments Occur in 1 out of 10,000 Americans Each Year
    Detached and Torn Retina Retinal Detachments Occur in 1 Out of 10,000 Americans Each Year A retinal detachment is not as common as other eye conditions such as glaucoma or macular degeneration, however… it is just as serious and it is a vision threatening condition which should be treated as an emergency. Dr. Randy Katz, Florida Eye’s Diabetic Retinopathy, Retinal Detachment & Macular Degeneration Specialist says that the sooner a retinal tear or detachment is treated the better the chances of saving the vision in the eye. What Is a Retinal Detachment? The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. When this occurs, if not promptly treated, retinal detachment can cause permanent vision loss. In some cases there may be small areas of the retina that are torn. These areas, called retinal tears or retinal breaks, can lead to a retinal detachment. Vitreous gel, the clear material that fills the eyeball, is attached to the retina in the back of the eye. As we get older, the vitreous may change shape, pulling away from the retina. If the vitreous pulls a piece of the retina with it, it causes a retinal tear. Once a retinal tear occurs, vitreous fluid may seep through and lift the retina off the back wall of the eye, causing the retina to detach or pull away. 2 Are You At Risk for a Torn or Detached Retina? A retinal detachment can occur at any age, but it is more common in people over age 40.

Larger field If there is no coordination between the two eyes the person will have double vision and confusion so as a compensatory mechanism for double vision the brain will cause suppression. The visual pathway is a plastic system that continues to develop during childhood until around 6-9 years of age. During this time, the wiring between the retina and visual cortex is still developing. Any visual problem during this critical period, such as a refractive error or strabismus can mess up this developmental wiring, resulting in permanent visual loss that can't be fixed by any corrective means when they are older Why fusion may fail ? 1.

  • Refractive Changes After Scleral Buckling Surgery
    Refractive changes after scleral buckling surgery Alterações refracionais após retinopexia com explante escleral João Jorge Nassaralla Junior1 ABSTRACT Belquiz Rodriguez do Amaral Nassaralla2 Purpose: A prospective study was conducted to compare the refractive changes after three different types of scleral buckling surgery. Methods: A total of 100 eyes of 100 patients were divided into three groups according to the type of performed buckling procedure: Group 1, encircling scleral buckling (42 patients); Group 2, encircling with vitrectomy (30 patients); Group 3, encircling with additional segmental buckling (28 patients). Refractive examinations were performed before and at 1, 3 and 6 months after surgery. Results: Changes in spherical equivalent and axial length were significant in all 3 groups. The amount of induced astigmatism was more significant in Group 3. No statistically significant difference was found in the amount of surgically induced changes between Groups 1 and 2, at any postoperative period. Conclusions: All three types of scleral buckling surgery were found to produce refractive changes. A correlation exists between additional segments and extent of refractive changes. Keywords: Retinal detachment/surgery; Scleral buckling/adverse effects; Refraction/ ocular; Biometry INTRODUCTION During the past several years, our Retina Service and others(1) have continued to use primarily solid implants with encircling bands. Only occa- sionally episcleral silicone rubber sponges are utilized. Changes in refrac- tion are frequent after retinal detachment surgery. The surgical technique used appears to influence these changes. Hyperopia(2) and hyperopic astig- matism may occur presumably by shortening the anteroposterior axis of the globe after scleral resections(1). Scleral buckling procedures employing an encircling band generally are expected to produce an increase in myopia and myopic astigmatism(1,3).

  • Refractive Error Is a Disease of the Eye, and We Should Treat It
    Refractive error is a disease of the eye, and we should treat it. believe that refractive error is a disease of the eye— no different from glaucoma, dry eye disease, and other issues for which we readily offer treatment. In the world of modern cataract and refractive surgery, we have the capability to correct visual Iacuity that is compromised due to astigmatism and other types refractive error, so why shouldn't we treat astigmatism during cataract surgery? A large percentage of our cataract patients, about 75%, have at least 0.50 D of astigmatism. Even this small amount of astigmatism can and often does create issues visually for patients. The higher the My Philosophy of level of astigmatism, the more it can affect vision. My philosophy is, why not try to help these people? Correcting their astigmatism will help them to achieve better visual acuity, and this is even more crucial in patients who elect a multifocal, extended depth of focus, or other premium IOL. It is important to educate patients about their astigmatism and to relay to them what we can do ASTIGMATISM to correct it. The level of care and attention to detail affects everything, from our surgical outcomes, to the practice’s reputation, to future referral patterns. THRESHOLDS AND BEST PRACTICES My threshold for astigmatism treatment is about 0.75 D.

I believe that correction of low astigmatism, especially, is low-hanging fruit, as it provides surgeons with an additional opportunity to improve their practices.

  • The Eyes in Marfan Syndrome
    THE EYES IN MARFAN SYNDROME Marfan syndrome and some related disorders can affect the eyes in many ways, causing dislocated lenses and other eye problems that can affect your sight. Except for dislocated lenses, these eye problems also occur in the general population, which is why doctors do not always realize they are caused by Marfan syndrome. It is important to know that, even though these problems occur in the general population, they are much more common in people who have Marfan syndrome. About 6 in 10 people with Marfan syndrome have dislocated lenses in one or both eyes. People with Marfan syndrome should see an ophthalmologist (a medical doctor who takes care of the eyes) to find out if they have any eye problems and learn how to care for their eyes. What are the common types of eye problems in people with Marfan syndrome? Some features of the eye related to Marfan syndrome that can cause vision problems include: Dislocated lenses About 6 in 10 people with Marfan syndrome have dislocated lenses in one or both eyes. This means the lens, located at the front of the eye, has slipped out of place because the connective tissue that holds the lens in place (called zonules) is weak. When this happens, the lens can slip in any direction—up, down, to the side, or back. It can slip a little or completely out of place, and anywhere in between. With the lens out of place, the eye can’t focus properly and vision is blurry. MARFAN.ORG | 800-8-MARFAN EXT.
