Avastin but not Lucentis increases risk of blood clots

Avastin and Lucentis are very different molecules with similar pharmacologic effects. Avastin have a longer half-life, which means it sticks around in the body longer before being broken down and excreted. The longer half-life may mean that it has a higher propensity to cause unwanted side effects than Lucentis. We have seen signs of this in the...


RISE Study: Lucentis is superior to laser for diabetic macular edema

The treatment options for diabetic macular edema continues to grow. Anti-VEGF therapies appear to be very effective, but suffer from short-term benefit and the need for continual retreatment. Sustained release steroid implants (Iluvien) is another recent development for DME. The advantage Iluvien has over Lucentis is that it is administered as a 2...

DICER1 deficit may cause dry AMD

This exciting discovery represents a potential breakthrough in our understanding of dry AMD. This landmark study clearly demonstrates a cause and effect relationship between toxic levels of RNA caused by DICER1 deficiency and geographic atrophy. It may also lead to treatments for dry AMD, but it remains to be seen whether treatments that were...

Association between asymmetry in cataract and asymmetry in AMD

There is continuing controversy regarding what, if any, risk cataract surgery conveys toward the development of AMD. The concern regarding cataract surgery stems largely from the fact that more blue light will reach the retina after a cataract is removed, and blue light has a higher potential to cause oxidative damage. Most studies that have...

A new study finds that genes in different pathways influence progression to different stages of age-related macular degeneration (AMD). AMD is known to be influenced primarily by genetic factors, although environmental and behavioral factors also play important roles. Multiple studies have shown that several genes in the alternative complement...

When patients are told by their ophthalmologist that they have early signs of age-related macular degeneration (AMD), they often ask about the risk of their AMD progressing. Long-term epidemiological studies that have collected information on the prevalence, incidence, and natural history of AMD provide data to answer this question. These studies...

Researchers have developed a risk score for developing geographic atrophy (GA) involving easily obtainable information among patients with bilateral large drusen. Choroidal neovascularization (CNV) and geographic atrophy (GA) are two forms of end-stage AMD. GA is responsible for about 10% of the severe vision loss attributed to the AMD, and...

About MyVisionTest has been developed to supplement the traditional Amsler Grid for those patients that have been instructed by their eye doctor to monitor their vision at home. MyVisionTest employs a technique known as entoptic perimetry to detect defects in your vision. Research has found entoptic perimetry to be superior to the traditional Amsler grid in detecting such defects. We also offer you the ability to save and review past test results, making it easier for you to detect changes in your vision over time.
