Macular degeneration – Its symptoms, causes, and management

Macular degeneration is an eye condition affecting the central vision. This means that people with macular degeneration fail to see what may be right before them. It’s predominantly an age-related condition, typically occurring in people over 50. It affects the retina’s central part, the macula, but those with it do not have complete vision loss, as they can still see things on the side. This article lists the treatment, causes, and symptoms of macular degeneration.

Macular degeneration symptoms
People do not show any noticeable signs or symptoms in the early stages. Moreover, it may not even get diagnosed until it aggravates or affects both eyes. During this phase, one may experience the below-listed symptoms:

  • One may notice deteriorating vision wherein everything looks blurry. One may also find it hard to recognize faces, read the fine print, or drive.
  • One may notice different or worse color perception.
  • Straight lines may look curvy or wavy.
  • One may notice blurry, dark areas in the vision’s center.

Those who experience or notice the symptoms mentioned above should immediately consult a doctor.

Causes
Unfortunately, experts do not know the exact cause of AMD, and there is no clarity on what triggers AMD in some people over others. However, some believe the environment and genes may trigger its development. Those who develop wet AMD first almost always have dry AMD. However, those with dry AMD do not necessarily get wet AMD.

Risk factors
Some common risk factors include the following:

  • High cholesterol
  • High blood pressure
  • Having light skin
  • Being assigned female at birth
  • Eating saturated fat

Treatment
One’s doctor will determine the macular degeneration treatments based on one’s medical history, overall health, age, nature and degree of the disease, personal preference or opinion related to treatment and the condition, expectations for the course of the disease, and endurance for specific procedures, low-vision therapies, and treatments.

Unfortunately, there’s no cure or fixed treatment for dry age-related macular degeneration. However, low-vision devices and vision rehabilitation programs can help build visual skills, devise new ways to perform everyday activities, and adapt to living with the condition. The primary macular degeneration treatment for wet AMD is based on anti-VEGF agents. VDGF refers to vascular endothelial growth factor. A high degree of VEGF in their eyes forms abnormal blood vessels that primarily inflict damage in wet AMD. So, doctors give patients anti-VEGF agents that help fight the disease process and lower the damaging impacts of these leaky blood vessels. These agents can also stabilize the vision of several patients.

Some patients see a noticeable improvement in their visual acuity with the treatment method mentioned above. They are administered directly to the affected eye. While it may sound daunting, this process is conducted under the effect of eyedrops that cause a temporary loss of sensation. Hence, patients are usually comfortable during the procedure. However, patients need multiple injections to maintain and retain the treatment effect. In some cases, other treatment options, like laser therapy, may also follow.

5 common medical conditions causing osteoporosis bone loss

5 common medical conditions causing osteoporosis bone loss

There are certain common medical conditions that are specifically linked with osteoporosis bone loss. Here’s what you need to watch out for. The bone is a living tissue, and as such it is constantly being broken down to create new bone. However, when the rebuilding process is slower than the breaking down process, the bones become fragile and brittle. This is what happens when you develop osteoporosis. Osteoporosis is more common in women than men, and affects about 200 million women all over the world. Even though this disorder affects women of all age and races, it is more common in older white and Asian women. When you are suffering from osteoporosis and it reaches an advanced stage, fractures become a part of daily life. The fractures that are associated with osteoporosis usually occur in your spine, hip, and wrist. The bones become so brittle that even everyday activities like bending over or stepping on to the pavement can result in fractures. Early stages of osteoporosis do not show any symptoms, but when it reaches an advanced stage, symptoms like loss of height, back pain, neck pain, fractures, and stooping posture can be seen. A simple bone density test that shows the extent of osteoporosis bone loss is used when you want to diagnose this disorder.

4 best foods for hemophilia

4 best foods for hemophilia

Hemophilia is a genetic disorder that is mostly diagnosed at a young age. The blood doesn’t clot as it should in people with this disease, causing excessive bleeding, which can turn life-threatening. The condition largely occurs due to the absence of certain blood-clotting proteins (called clotting factors), although it can also be acquired due to an immune system issue. Physical therapy, clot-preserving medications, and vaccinations are viable treatment options. Alternatively, certain food choices can also help manage the symptoms and prevent the condition from worsening. In this article, we’ll take a look at some of the beneficial foods to eat for people with hemophilia: Whole grains Oatmeal, brown rice, and barley are a few of the healthiest whole grains to eat for hemophilia patients. These foods contain fiber and nutrients that help stabilize blood glucose levels. By lowering the risk of heart disease and stroke, these foods prevent serious complications associated with hemophilia. Whole grains also reduce chronic inflammation, which can be touted as a major contributor to internal bleeding. Calcium-rich foods Important for the growth and maintenance of the bones, calcium is paramount for hemophilia patients. The nutrient helps keep tooth and bone health in check, preventing damage and subsequent blood loss.
