Warning for Macular Degeneration Patients Who Undergo Cataract Surgery

Macular Degeneration & Cataract Surgery

Eye disease and aging generally go hand-in-hand.  That means that more people are likely to need surgery for cataracts, but that also means that those same patients are likely to suffer from other conditions like macular degeneration, glaucoma, and diabetic retinopathy.  According to the OSN Supersite, this changes the ways that doctors counsel their patients and how they proceed with treatment plans, especially in relation to cataract surgery.

Some sources say that the risk of AMD decreases after one undergoes cataract surgery, but no conclusive scientific studies on the topic have yet been published.

Avoid Multifocal IOL Implants

According to Rosa Braga-Mele, MD, FRCSC, OSN Cataract Surgery Section Editor, people with AMD should probably avoid multifocal IOL implants (lenses intended to help you live without glasses because nearsightedness and farsightedness are meant to be corrected).  Dr. Braga-Mele says that these lenses are not ideal for cataract surgery patients with AMD “because of the fact that contrast sensitivity is decreased with a multifocal implant and contrast sensitivity is already decreased” when people have macular degeneration.  Source: “Cataract surgery with comorbidities requires careful surgical management” at osnsupersite.com.

Manage Your AMD

It is especially important that those who suffer from cataracts as well as macular degeneration manage their AMD.  Take natural approaches to preventing the deterioration of your sight due to AMD by eating well, wearing UV protection sunglasses, reducing stress, and taking high quality supplements as described in our “self-help” protocol.

 

Cataract Surgery Not Linked to Increased Age-Related Macular Degeneration

cataract surgery lens replacementA large study has found no association between prior cataracts surgery and the development of Age-Related Macular Degeneration (ARMD).[1.

Dry Macular Degeneration May Be Treated by Anti-Placental Growth Factor Antibody, Aflibercept

senior citizen macular degenerationAflibercept is currently a treatment for wet Age-Related Macular Degeneration (AMD), but it may also prove useful for patients with dry AMD.

The researchers accidentally discovered that an anti-placental growth factor antibody could provide retinal protection for the dry form of Macular Degeneration. They tried using a known protein called placental growth factor (PlGF) on a simulation of wet AMD in animal tissues. The PIGF made the retinal cells worse. So, they tried an anti-PlGF antibody treatment. This treatment provided protection against retinal damage.

Aflibercept is an anti-PlGF antibody treatment. It is used Continue reading “Dry Macular Degeneration May Be Treated by Anti-Placental Growth Factor Antibody, Aflibercept”

AMD Research – Part 2

macular degenerationScientists are putting significant focus on Age-Related Macular Degeneration in their research. This eye disease strikes mostly older adults, over aged 50. The “Baby Boomer” generation is well above age 50, as are their living parents. Understanding the causes and potential treatments for Macular Denegation (ARMD) are important, because vision-impaired elderly people need extra help with their daily activities. Also, quality of life is lowered when vision is poor.

The macula is a tiny yellowish spot in the back of the eye, on the retina. It allows for central vision. Central vision is possible because of the macula. If it breaks down, reading, writing, watching TV, cooking, driving and even facial recognition are impaired. Macular Degeneration is degenerative, meaning that it gets worse over time.

ARMD comes in two forms. The more common Continue reading “AMD Research – Part 2”

Lutein Absorption Higher as a Solid-Lipid Particle Complex

egg yolkLutein absorption can be improved by adding solid-lipid particles to the formula.  What does that mean?   Lipids are fats and solid-lipids are fats which are solid at room temperature.  Researchers have noted that lutein from egg yolks is more readily absorbed than the ester form of lutein. Researchers wanted to know whether combining ester lutein with egg-like phospholipids and fatty acids  would improve its absorption rate.

Lutein Absorption Studied

A pilot study found that lutein in the form of a solid-lipid particle complex appeared to be more readily absorbed than the traditional  ester supplements. This supplement was prepared from enriched egg yolk. The results mean that more bio-available supplements of this important carotenoid antioxidant could come in the near future.

Research demonstrates that Lutein has a protective and supportive effect on eye health. The macula at the back of the eye is yellow due to lutein and zeaxanthin. They filter blue light, protecting the eye. Without proper intake and absorption of these two carotenoids, the eye can develop several diseases including Macular Degeneration (AMD).

The supplement is called a Continue reading “Lutein Absorption Higher as a Solid-Lipid Particle Complex”

AMD Research: Part 1

age-related macular degeneratio ARMD Age-Related Macular Denegation is a significant cause of vision loss that can often be managed and even improved through targeted nutritional support. It affects mostly people over age 50. While the precise cause of ARMD is not clear, oxidative damage is suspected as being a major factor. It strikes the elderly possibly due to poor diet and nutritional intake over a lifetime, less efficient absorption of nutrients and poor circulation as the body ages. The care needed by vision-impaired elderly could become overwhelming. Let’s take a look at some of the newest research in preventing macular degeneration, as well as treatment and support options.

Symptoms & Diagnosis

Central vision is possible because of the macula. It is a small, yellow-colored Continue reading “AMD Research: Part 1”

Can Oxidative Damage Cause Macular Degeneration and Cataracts?

vegetables and fruits containing antioxidantsAntioxidants have been studied as a way of preventing eye diseases such as macular degeneration and cataracts. Oxidative damage (free radical damage) may be a contributing cause of these diseases. People concerned about developing these problems may consider taking both dietary and supplemental antioxidants, such as fruits, vegetables, and supplements like lutein, zeaxanthin, glutathione, Continue reading “Can Oxidative Damage Cause Macular Degeneration and Cataracts?”

Fucoxanthin / Fucoidan – Eye Nutrients of the Future?

seaweed2Chinese scientists have identified nutrients that come from marine algae that may prove to provide even better support for vision health problems due to computer eye syndrome than the antioxidants lutein and zeaxanthin. Fucoxanthin[1. Y. Liu, et al, Protective Effect of Fucoxanthin Isolated from Laminaria japonica against Visible Light-Induced Retinal Damage Both in Vitro and in Vivo, Journal of Agricultural and Food Chemistry, January, 2016.] comes from a brown seaweed where it is the primary part of the light-absorbing mechanism of the plant.  It is what gives seaweed a brown or olive-green color.

Microcurrent Stimulation May Help Macular Degeneration

microcurrent stimulationA small study has shown microcurrent stimulation (electrotherapy) to benefit macular degeneration patients. While the study did not have controls, the research on 25 eyes with dry age-related macular degeneration, and 6 eyes with wet age-related macular degeneration found:

  • Significant increases in visual acuity for most of the dry AMD patients (Wilcoxon one-sample test)
  • Twice as many dry AMD patients had improved visual acuity (52%) than deterioration (26%). The improvements were usually large, while deteriorations were very small.
  • The sample size of wet AMD eyes was too small to draw many conclusions; however, all but one had an increase in visual acuity, and none of them deteriorated.

Low Intake of Antioxidants & Lutein Associated with Macular Degeneration (ARMD)

antioxidant vegetable for eyesEating plenty of fruits and vegetables helps ward off a common eye disease, age-related macular degeneration (ARMD). A study in Acta Ophthalmologica looked at the relationship between intake of antioxidants (including the antioxidant lutein) and the incidence of macular degeneration. It found that people with low intake of antioxidants were twice as likely to have this eye disease versus controls.
