Age-related macular degeneration (AMD) new drug filed one after another – age-related macular degene
Article by jekky
Has become the blindness in the elderly over the age of 65 the culprit. But the good news is that there are a number of new drug R & D line drug treatment of this disease. With the average age of the U.S. population increases, the incidence of age-related macular degeneration is rising. According to the U.S. Ophthalmology Society (National EyeInstitute) statistics, U.S. age-related macular degeneration patients have more than 800 million people. Effect of general and current high price of treatment, and after Glass Injection treatment is limited because of cost. Being on good effect and the higher cost of treatment rising demand push Pharmacy Companies are working to develop cost-effective high drug resistance to age-related macular degeneration. Present, for the treatment of age-related macular degeneration, ranibizumab, bevacizumab intravitreal injection required monthly, this lengthy delivery process difficult patients. Pharmaceutical companies are trying to develop eye drops to treat age-related macular degeneration. Othera pharmaceutical companies are carrying out OT-551 for the treatment plan atrophy?? A newer type of dry age-related macular degeneration, has entered a phase clinical trials. In preclinical studies, OT-551 demonstrated anti- Oxidation , Anti-angiogenic and anti-inflammatory activity. OT-551 is carrying out plans atrophy multi-center clinical trial, a two-year trial, 198 patients in the U.S. more than 20 research centers to participate in the test eye. Othera is working with the U.S. National Eye Institute to conduct a joint OT-551, another phase clinical trial to determine the drug on patients with bilateral atrophy map the impact of disease progression. In 2008, the upcoming phase clinical trials, Othera the company will study the OT-551 as an assistant drug ranibizumab, ranibizumab injection to reduce the frequency, in order to achieve the same results or better results. There is a drug in the study is CoMentis’s ATG3 ophthalmic solution. Currently, ATG3 in Phase clinical study aimed to evaluate the old wet macular degeneration drug Security Sex. CoMentis company hopes to gain in 2008 for 6 months of the experimental data. This year in August, Regeneron Pharmaceuticals and Bayer Co-initiate the VEGFTrap-Eye Phase clinical trials. VEGFTrap-Eye is a humanized soluble vascular endothelial growth factor fusion protein, energy and all types of vascular endothelial growth factor A and placental growth factor binding, thereby treating age-related macular degeneration. The early phase clinical studies have shown that the use of VEGFTrap-Eye12 months after the party in the reduction of retinal thickness Mask Statistically significant differences. As retina more sensitive to oxidative injury, and many people believe that antioxidants can be added on the progress of the disease have a significant impact. In fact, the age-related eye disease study (AREDS) has shown that antioxidants in preventing and delaying the progress of the disease is very useful. Taking Vitamin C , E, zinc and -carotene in patients with patients taking the drug compared to the control, the incidence rate has dropped by 28%. Phase of age-related eye disease study (AREDS2) is on the lutein, zeaxanthin, and long-chain Omega-3 fatty acids delay the age-related macular degeneration in the progress of the role of the clinical trial were enrolled in December will be the end of this year. GenVec Inc. is looking for an innovative method of treatment of age-related macular degeneration. This treatment is currently in phase I clinical trials, the treatment delivery vector for use AdenovectorDNA pigment epithelium derived factor ( PE DF) gene. AdPEDF can effectively inhibit the growth of blood vessels into the eye is not correct, prevention of damage caused by loopholes in the blood vessels.

Retinitis Pigmentosa and Lutein
A report published in Archives of Ophthalmology showed that non-smoking sufferers of RP experienced a reduction in the rate of loss of vision following treatment with the protein lutein. The study divided its sample into two groups, one of which was given 10mg of lutein a day for 12 weeks, and then 30mg of lutein a day for 24 weeks, while the other group were given a placebo for 24 weeks, then lutein at 30mg for 24 weeks.
In both the studied groups, it was shown that there is a 6-week delay experienced between the start of taking lutein and it having any effects on the patient. It was further shown that the reduction in loss of vision was greatest in visual acuity (clarity of sight) and contrast sensitivity.
Lutein is already present in the light receptor cells in the retina and it is believed to serve as an antioxidant. A different study, carried out in year 2000 showed similar results, but also showed that people with blue eyes as well as those that were taking vitamin A (in a beta-carotene form, rather than in retinyl palmitate used in the current study) supplements experienced the greatest reduction in their vision loss.
There are concerns over the validity of this research though, especially as the authors of the paper used linear methods to predict loss of vision, where retinitis pigmentosa may not cause linear loss of sight. Other concerns have been raised over the safety of taking high doses of vitamin A for extended periods of time, as the study only showed that lutein is safe to take for extended periods of time in the short term.

Information About Vitreous Floaters
In our eyes, there is a very special transparent part, called vitreous humor that decides the shapes of our eyes. The main ingredient of vitreous humor is liquid.
Where is the specific location of this substance? It lies between our lens and retina. To some extent, our retinas are fixed by the force generated by this substance.
Vitreous humor is a very complicated tissue. For example, in it are thousands of blood vessels and fibers that stretched to retinas.
Here is an eye problem that is firmly related to vitreous humor. As mentioned earlier, our retinas are fixed by the force generated by this tissue. What will happen if this force becomes weaker?
As we grow old, vitreous will become weaker and weaker. Ultimately, it shrinks and can not be firmly fixed. Therefore, the fibers that connected to retina become loose and vitreous floaters may emerge.
With loose vitreous humor, the aqueous humor in suffers’ eyes will be accumulated more and more, but gel remains unchanged.
This process has lead to great imbalance. Why it is called vitreous floaters? There should be something that floats. It is true that some debris from retinas will not be eliminated once they get into the transparent part-vitreous humor. Now that there is something that affects the transparency, the eyes will see some shadows and floaters in them.
This eye problem may lead to some discomfort and annoyance to sufferers. But this is normal and harmless, for this is a natural phenomenon. Most old people are suffering from this problem.
Generally, vitreous floaters can not be treated, for it is a natural problem. If the symptom is too serious, some eye surgeries are good methods.
