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...

Selective retina therapy for acute central serous chorioretinopathy

The search continues for a safe and effective means of speeding the resolution of acute CSC. Because most cases of acute CSC will resolve fully without intervention, it is imperative that any treatment that is undertaken have a very low risk of adverse effects. Safety-enhanced photodynamic therapy is currently the most appealing of the available...

Pressure-lowering medication ineffective against IOP spikes after intravitreal injections

Very high IOP following intravitreal injection is a common and serious problem. Even transient pressure spikes can cause serious damage to the eye, and the risk is compounded by the necessity for repeated monthly injections. When a patient's IOP shoots up very high following an injection, fluid can be removed from the eye to rapidly return the...

Recurrence intervals after anti-VEGF therapy for AMD

There is a general impression among retinal specialists that some patients tend to go longer between recurrences than other patients. What is less clear is whether these intervals are consistent enough to be a basis for treatment decisions. If we knew that patient A tended to recur every 6 weeks and patient B tended to recur every 12 weeks, then...

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.
