Drugs for Age-Related Macular Degeneration: Are They Too Expensive?

The effectiveness of treatments for age-related macular degeneration (AMD) is an important issue, but so, too, is their cost. In a study reported in the journal Retina (volume 30, page 212) three widely used therapies for age-related macular degeneration -- pegaptanib (Macugen), ranibizumab (Lucentis) and photodynamic therapy (PDT) with verteporfin (Visudyne) -- were investigated for their treatment outcomes as well as their Medicare-associated costs.

How Diabetic Retinopathy Affects Vision

It's estimated that more than four million Americans with diabetes age 40 and over suffer from diabetic retinopathy – a serious condition that can lead to vision loss. What is diabetic retinopathy and how does it affect the eye? Read on for a brief explanation. More...

New Technologies to Brighten Low Vision

Assistive devices for people with low vision have come a long way since the days of clunky magnifying lamps and magnifying glasses. New technologies can help you see better, increase your independence and help you conduct transactions online from the comfort of your home. Here are several devices you might want to try. More...

Lowering IOP Through Exercise

If you've just been diagnosed with glaucoma, you’ll want to do everything you can to remain as healthy as possible for as long as possible. Can exercise help you achieve this goal? While the mainstay of glaucoma therapy remains lowering intraocular pressure (IOP) with medication, laser treatment or surgery, some evidence suggests that a regular exercise program can help support your medical therapy. More...

A Look at Two Alternative Treatments for AMD

Are you thinking about trying an alternative therapy to treat age-related macular degeneration (AMD)? Like anyone with a serious illness, you might be tempted to try something that sounds like a miracle cure. But beware, snake-oil salesmen abound. More...

How to Make the Most of Limited Vision and Mobility

Taking a brisk walk is tough to do when you can't see well. Even a short stroll can become a dangerous obstacle course as you swerve to maneuver curbs, check traffic and avoid bumping passersby. Still, some people with limited vision clip along quite well, and researchers at Johns Hopkins are trying to understand why some fare better than others -- and which of their lessons can be passed along. More...

Staying on Track With Your Glaucoma Regimen

If you've ever taken any medication for more than a few weeks, you know how difficult it can be to stick to a strict drug regimen. If you have glaucoma, following the prescribed regimen may be an even greater challenge. Not only might you need to use glaucoma eyedrops multiple times each day, but you also need to get them into your eye -- a more complicated task than swallowing a pill. More...

Focus on the Intraocular Lens Implant (IOL)

Cataract surgery involves removing all or part of the lens and replacing it with an intraocular lens implant (IOL). The quarter-inch plastic lens implant is typically inserted into the lens capsule behind the iris (posterior chamber intraocular lens). However, when the lens capsule is absent, a different kind of intraocular lens may be inserted in front of the iris (anterior chamber intraocular lens). More...

How Early Should You Treat People at Risk for Glaucoma?

Eye pressure that is higher than the normal range is an important risk factor for primary open-angle glaucoma – the most common form of glaucoma. Early treatment reduces the risk of developing open-angle glaucoma, according to the Ocular Hypertension Treatment Study, but should all ocular hypertensives be treated, and if not, is there harm in waiting on treatment for those at lower risk? More...

How Hypertension Can Put Your Vision at Risk

If you have ever experienced love at first sight, you know that the heart and the eyes share an intimate connection. Unfortunately, the eyes and the heart are also linked in a less romantic way: through hypertension, or high blood pressure. More...

Blue-Blocking Intraocular Lenses and Insomnia: Is There a Link?

During cataract surgery the patient’s lens is removed and a plastic intraocular lens (IOL) implant is inserted. Once inserted, lens implants require no care. As with any device, however, complications can occur. Recently a reader asked us: "After my husband's cataract surgery, he started having trouble sleeping. Could his blue-blocking intraocular lenses be responsible?" Here’s what the research suggests. More...

3 Key Surgical Procedures to Repair Retinal Detachment

Retinal detachment is a vision-threatening condition in which the retina becomes separated from the underlying layers of the eye. The greatest risk of retinal detachment occurs after cataract surgery among people who are also very nearsighted. Even in the absence of cataract surgery, being very nearsighted is the principal risk factor for retinal detachment. More...

How Cataracts Affect Your Vision

Sooner or later many of us will develop a cataract. Here in brief is an explanation of how cataracts affect vision. More...

Focus on Diet and Age-Related Macular Degeneration

Ten years ago, researchers involved in the landmark Age-Related Eye Disease Study (AREDS) demonstrated that high doses of selected antioxidants and zinc slowed the progression of age-related macular degeneration (AMD) by a factor of 25 percent and reduced the risk of related vision loss by a factor of 19 percent. However, there was a slight catch: Only people with intermediate or unilateral advanced disease benefited from taking the high-dose cocktail, which consisted of vitamins C and E, beta-carotene and zinc.

5 Common Causes of Cataracts

Currently, no effective drug therapy exists to prevent cataracts from forming. However, cigarette smoking, certain medications, eye injuries, sunlight, diabetes and even obesity can increase the risk of cataracts. More...
