Eye floaters

Floaters are shadows of small to large objects that appear to hover in sight. The size of floaters can vary, from small black dots to bigger shadows like long straps. Floaters usually appear when someone sees bright light like the sun or looks at a basic color like white for too long.

Eye floaters

As you age, the vitreous — a jelly-like material inside your eyes — becomes more liquid. When this happens, microscopic collagen fibers within the vitreous tend to clump together. These bits of debris cast tiny shadows onto your retina, and you perceive these shadows as eye floaters.

In general, floaters occur due to age. In the normal eye, light enters through the lens and cornea of ​​the eye and continues towards the retina located at the back of the eye. Between the front and back of this eye there is a supple mucous fluid that serves to maintain the shape of the eyeball, called the vitreus. As you get older, the thickness of the vitreous will decrease, and the residual stagnant dirt will begin to appear in it. The remaining dirt that appears is floaters.
Regardless of age, there are several factors that can cause floaters such as accidents that hurt the eyes, farsightedness, eye inflammation, infections, complications of diabetes, retinal tears, intraocular tumors, or migraines.

In general, floaters do not cause pain but may cause excessive vision. Symptoms of floaters that are classified as harmless are like seeing small spots or lines like the shadow of a rope in the eye, and still follow the vision path for a while. However, if you experience unusual symptoms such as spots or the shadow of the rope to change size, see flashes of light, shakiness of peripheral vision, blurred vision to experience pain in the eye, it is strongly recommended to see a doctor as soon as possible.

Causes of Floaters
Floaters can be caused by a variety of conditions, including:
  • As we get older, the conditions in the eyes change. Vitreous fluid which initially has a chewy consistency to maintain the shape of the ball over time will melt and lose its elasticity. As a result, the vitreus will shrink, and some parts of the eyeball will be attracted. As the vitreus constricts and grows dense, the residual debris will begin to emerge which eventually blocks the vision pathway.
  • Eye bleeding. There are several things that can cause bleeding in the vitreus, including direct trauma to the eye or when there is a disturbance in the blood vessels in the eye, as happens in the case of diabetic retinopathy.
  • Inflammation of the back of the eye. This condition is also called posterior uveitis, where the uvea layer (the lining in the back of the eyeball) is inflamed due to infection.
  • Retina tear. This retinal tear can occur when the shrinking vitreus can attract the retinal layer. If not treated immediately, this retinal tear will cause the retinal layer to escape, which can be at risk for blindness.
If you experience unusual floaters problems, it is highly recommended to see an ophthalmologist. Explain completely about your symptoms and history of the disease (especially the eyes) to make it easier for the doctor to diagnose. If the doctor finds symptoms that are severe enough, especially those related to the retina (which is usually rare), the doctor may take several tests such as:
  • Physical test. The doctor will see the activity of your retina through the pupil and monitor the small size when exposed to light. If it cannot be diagnosed directly, the doctor will use liquid eye drops to dilate the pupils and make it easier for the doctor to check the condition. In addition, the doctor may also use a tool called a slit lamp along with bright lighting to examine the inside of the eye. Usually after testing with the help of eye drops or slit lamp, your vision will feel blurry or glare for several hours. It is recommended not to drive or carry out outdoor activities until the glare subsides.
  • Tonometry Test. If needed, a tonometric test or test to check eye pressure can be done to see the ability and strength of the patient's eye (intraocular pressure).
Floaters usually do not require special treatment because they can disappear on their own. However, if the levels of floaters are considered to be very disturbing to vision, there are several treatment options commonly recommended by doctors, such as:
  • Laser Therapy. The doctor will direct a special laser beam on the glass body (vitreous humor) to destroy the floaters into smaller particles, so as not to disturb vision. This therapy must be done carefully because it can damage the retina if laser direction is not correct.
  • If laser therapy doesn't help much, vitrectomy surgery can be an option for people with floaters. This operation is carried out by lifting the glass body along with floating small grains and replacing it with sterile salt liquid. Before taking a vitrectomy, it is recommended to consult with a doctor first to find out the risks and side effects that might occur.
Floaters generally do not cause complications, but the risk can increase when patients take steps to vitrectomy, such as:
  • Tearing and bleeding in the retina
  • Ablation or detachment of the retina from the eye
  • Cataract
See a doctor immediately if you experience complications or feel unusual differences after surgery or other therapies.

Floaters generally cannot be prevented. Even so, you are advised to check eye health at the optics or eye clinic at least every 2 years to determine the health status of your eyes. The examination also serves to ensure that floaters are not a symptom of a more serious condition that can damage eye vision.

Cold Urticaria

Overview Cold allergy or in medical terms called cold urticaria is the reaction of the skin to cold which causes itching to appear and the skin becomes reddish in color. The severity of cold allergy symptoms that appear on each person is different. Some people can lose consciousness, experience very low blood pressure, and even the worst can cause death. Ages are the age most often affected by cold allergies, but usually will disappear completely within a few years. Symptoms Usually cold allergy symptoms appear when the skin is exposed to cold water or cold weather (below 4 degrees Celsius). Cold allergies are also more at risk of appearing in conditions that are windy and damp. The following are some cold allergy symptoms that can occur. Hands feel swollen when holding cold objects. Itchy lesions appear on the area of ​​the skin exposed to cold air. The lips and throat feel swollen when eating cold food or drinks. Reddish skin. Allergic reactions are usually most seve

COVID-19 (coronavirus) Quarantine, Self-Isolation and Social Distancing

COVID-19 (coronavirus) quarantine, self-isolation and social distancing Learn the difference between quarantine and self-isolation amid the COVID-19 (coronavirus) pandemic — and why it matters. You've read about people self-quarantining, social distancing, or isolating themselves during the coronavirus disease 2019 (COVID-19) pandemic. You may be confused about the various terms and wonder what you should be doing. These terms describe approaches for limiting the spread of disease during epidemics and pandemics:   Social distancing.  Keeping space between yourself and other people outside your household to prevent the spread of disease. Quarantine.  Separating people and limiting movement of people who have or may have been exposed to the disease to see if they become ill. Isolation.  Separating people who are ill from others to keep the disease from spreading. Social distancing   You're likely practicing social distancing if there's ongoing community spre

Ways to fight coronavirus transmission at home

Ways to fight coronavirus transmission at home Used properly, most common household disinfectants will kill the virus that causes COVID-19. Doctors and researchers are gaining a greater understanding about the coronavirus disease 2019 (COVID-19) outbreak and how the virus can spread. Public health messages emphasize the importance of frequent, thorough hand-washing and social distancing to slow the spread of  COVID-19 .   You can also take steps in your home to keep the virus from spreading. No special supplies are required. You likely already have what you need. How is COVID-19 spread?   The virus that causes  COVID-19  can be spread by contact with someone who has  COVID-19 , as well as contact with surfaces or objects that person has touched. When someone with  COVID-19  sneezes or coughs, respiratory droplets are released into the air. Droplets typically don't travel far — no more than 6 feet (about 2 meters). The virus may stay on surfaces from hours to days.
