Macular Degeneration

AMD Examples book

Macular Degeneration is a degenerative condition affecting the central part of the retina (the macula) resulting in distortion or loss of central vision. It occurs especially in older adults; in which case it is called age-related macular degeneration.

amsler gridAfter a comprehensive eye health examination, if AMD (age-related Macular degeneration) is suspected, other tests may be performed. Including The Amsler Grid test.

This test is an important, but simple tool that tests macular vision and helps detect specific types of vision loss associated with AMD. This test uses a grid chart and can be administered in the office, but also may be performed at home by the patient.

You can download and take The Amsler Grid Test by clicking on this link.

We might also perform a Visual Field Test which is sophisticated central visual field testing that can show loss of central vision sensitivity even though visual acuity may not be affected.

Hemianopsia

Hemianopsia img

Hemianopsia is a debilitating visual condition that affects roughly 1 in 3 stroke patients. It can also be triggered by a brain injury or brain tumor. To the patient, it’s as if one side of their visual field simply disappears. To a layperson, this is hard to imagine, and even harder to explain. Patients with hemianopia have two major complaints related to this devastating condition: it’s hard to read, and it’s hard to get around without bumping into things (mobility).

Hemianopsia Treatment

During this examination, we’ll determine what functional field of vision a person has left and determine the best way to expand that field of vision.

One option used to help restore some of the field of vision is a vision rehabilitation system known as NOVA Vision. This system takes advantage of the brain’s ability to “rewire” itself. For more information on this go to: http://www.novavision.com/

There are also Field Expanding Gasses. These are special glasses that are fitted for you with a prism in each lens. These prisms bend incoming light so that it reaches the non-damaged section of your visual field.

Glasses that are recommended for those with Hemianopsia are The Peli Lens™. The Peli Lens™ is designed specifically to help with mobility. The Peli Lens uses high powered prisms placed in the peripheral vision to expand a Hemianopic patient’s awareness of their blind side by over 30 degrees. There is also a patented oblique configuration available that may make it possible to drive. However, driving depends on your state’s laws.

Glaucoma

glaucomaGlaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in your eye.

Glaucoma Treatment

Treatment of open-angle glaucoma — the most common form of the disease — requires lowering the eye’s pressure by increasing the drainage of aqueous humor fluid or decreasing the production of that fluid. Medications can accomplish both of these goals. Surgery and laser treatments are directed at improving the eye’s aqueous drainage.

If not diagnosed early, open-angle glaucoma may significantly damage vision and even cause blindness. That is why it’s so important to have your eye doctor test you regularly for glaucoma. Once diagnosed, glaucoma is usually controlled with eye drops that reduce eye pressure. Glaucoma is a life-long condition and needs continual follow-up with your eye doctor.

Glasses recommended for Those with Glaucoma are:

  • Full Diameter Telescopes
  • Bioptic Telescopic Glasses
  • Clear Image Microscope Glasses
  • E-Scoop Glasses
  • Field Expanding Glasses

Diabetic Retinopathy

diabetic retinopathyDiabetic retinopathy is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy might cause no symptoms or only mild vision problems, but it can lead to blindness. The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.

Diabetic Retinopathy Treatment

Your treatment will depend on what kind of retinopathy you have and how severe it is. Dr. Huggett and his team will work with you to maximize your remaining vision.

Controlling Blood Sugar

Controlling your blood sugar and blood pressure can stop vision loss. Carefully follow the diet your nutritionist has recommended. Take the medicine your diabetes doctor prescribed for you.

Medication

One type of medication is called anti-VEGF medication. These include Avastin, Eylea, and Lucentis. Anti-VEGF medication helps to reduce swelling of the macula, slowing vision loss and perhaps improving vision. This drug is given by injections (shots) in the eye. Steroid medicine is another option to reduce macular swelling. This is also given as injections in the eye. Your doctor will recommend how many medication injections you will need over time.

Laser surgery

Laser surgery might be used to help seal off leaking blood vessels. This can reduce swelling of the retina. Laser surgery can also help shrink blood vessels and prevent them from growing again. Sometimes more than one treatment is needed.
