40 Year Old Man Is Diagnosed With Eye Cancer Because He Did This Every Night…

Who does not stay hours scrolling the screen of his phone, in bed, last reflex before turning off the night light. This well-anchored mania in addition to seriously mortgage our sleep would also harm our eyes. Between smartphones, LED bulbs, tablets, television, computers we spend more than seven hours a day exposed to these light beams, close to ultraviolet light and which prove extremely dangerous for the retina, this sensitive organ of vision.

Beware of the dangers of blue light

Studies are unanimous, blue light causes molecular changes in the retina, the lens and the cornea. Some molecules turn into free radicals and predispose to degeneration of the structures of the eye and potential damage to the cells, especially cataracts, or even cancer of the eye.

In the short term, the subject feels discomfort and visual fatigue. The more we scrutinize our phone, the more we tend to squint our eyes because of the dazzling blue light and diffuse, so that visual tension and dry eye creates a headache. Without omitting the visual performance that is affected, we find it difficult to see details and contrasts.

On the other hand, researchers from the University of Michigan in the United States have observed the impact on sleep of an increased use of the smartphone. Their research has shown that blue light delays our biological clock and accentuates our "social jet lag", as it disrupts the production of melatonin, a chemical substance secreted by our body that promotes falling asleep.

The researchers identify a risk to the eye: age-related macular degeneration, which corresponds to an alteration of part of the retina (the macula), this precise area that treats 90% of the visual information that our Eyes.

What is macular degeneration?

"Subretinal neovascularization" occurs when the macula is affected. Tiny blood vessels proliferate in large numbers under the retina. These lines, which undulate in the center of the visual field, let pass through their walls the serum and the blood. A bubble eventually forms and swells the retina which damages the vision.

What is a melanoma of the eye?

A rare form of cancer, malignant melanoma of the uvea affects melanocytes, those cells that nest in the iris or choroid, and produce melanin, a pigment that colors eyes and skin.

Eye Cancer Symptoms

These signs are unusual and may reveal another disease of the eye. Tearing eyes that burn or tingle are not a sign of melanoma. Symptoms depend on the location of the tumor. If it forms in the iris, it reveals a black spot in the field of vision. If the melanoma develops inside the eye, the tumor reaches a certain volume and causes a decrease in visual acuity. Also, lightning flashes or "flying flies" cross the visual field when the tumor grows and causes detachment of the retina.

Retinoblastoma is a form of cancer of the retina that affects children in particular. This disease is often hereditary and can reach an eye. Strabismus and a leucocoria (white reflection in the pupil) characterize it.

Treatment of Macular Degeneration

Macular degeneration can be treated with laser surgery that destroys the small blood vessels that are likely to cause haemorrhage in the macula. It is also possible to inject drugs into the eye that slow down the growth of blood vessels.

Treatment of eye cancer
  • Surgery removes the tumor if it is not too large. In case of recurrence or complications, enucleation or extraction of the eyeball and part of the optic nerve is performed.
  • Radiation therapy or proton therapy which consists of irradiating cancer cells by ionizing radiation. In 90% of the patients, the sight remains).
  • Focus at the Curie Institute, brachytherapy this technique of radiotherapy which consists of diffusing radioactive substances directly into the tumor.
