Psychiatric disease increases recurrence of central serous chorioretinopathy

It has long been recognized that CSC is associated with certain personality types - "Type-A", highly strung, highly stressed individuals. The results of this study are consistent with the view that CSC is associated with certain mental traits.

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...


Omega-3 fatty acid and fish intake prevents AMD

DHA and EPA are the "active ingredients" of fish oil. This study finds that greater dietary intake of fish oil, or eating fish at least once per week, can help prevent the onset of AMD. This finding is significant because most research focuses on ways to slow the progression of AMD among those that already have the disease. We have much less...


Benefits of the treat-and-extend approach for AMD therapy

The argument in favor of using Avastin over Lucentis is almost always economic. Because Avastin is much cheaper than Lucentis, patients and their insurance provider can save lots of money by using Avastin. However, the "treat and extend" dosing strategy reveals another potential benefit of Avastin - its longer half-life. There are several 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.
