INNER EYE WALL [4 records]

Record 1 2025-05-29

English

Subject field(s)
  • Visual Disorders
  • Human Diseases - Various
CONT

In people with diabetes, too much blood sugar can damage the tiny blood vessels at the back inner wall of the eye, called the retina, or block those vessels completely. This condition is diabetic retinopathy. Tiny bulges, called microaneurysms, form in the blood vessels, leaking fluid into the retina. The fluid can cause swelling in a part of the retina called the macula. This serious eye problem is diabetic macular edema. It can cause vision problems or blindness.

  • Troubles de la vision
  • Maladies humaines diverses
CONT

Le diabète peut entraîner des problèmes oculaires, dont l'œdème maculaire diabétique (OMD), qui cause une perte de vision. [...] L'œdème maculaire diabétique survient lorsque de minuscules vaisseaux sanguins qui alimentent la rétine commencent à fuir, provoquant un gonflement et des problèmes de vision.

Record 2 2023-09-22

English

Subject field(s)
  • Atmospheric Physics
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

... the rotating, localized lowering of the cloud base beneath the rain-free portion of a thunderstorm that often precedes tornado development ...

CONT

Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest (inflow) side of the thunderstorm. Even though this cloud is lowering, it remains attached to the rain free cloud base of the thunderstorm. It is usually located south or southwest of the visible precipitation area, and marks the strongest updraft in the thunderstorm. The wall cloud develops as the strong updraft draws in surface moisture from several miles away.

OBS

"Wall cloud" also is used occasionally in tropical meteorology to describe the inner cloud wall surrounding the eye of a tropical cyclone, but the proper term for this feature is "eyewall. "

CONT

Le précurseur typique de la tornade est le mur de nuages. C'est une partie de la base du nuage qui semble s'abaisser vers le sol. On le trouve normalement sur le flanc arrière droit de l'orage. Autrement dit, si l'orage arrive de l'ouest, il faut regarder vers sa partie sud-ouest. Le mur de nuages se forme dans la zone sans précipitations et montre généralement un mouvement de rotation, sous la base du nuage.

The ring of thunderstorms that surrounds a storm’s eye.

OBS

The heaviest rain, strongest winds and worst turbulence are found in the eyewall.

Record 4 2012-11-14

English

Subject field(s)
  • Atmospheric Physics
CONT

Some of the outer rainbands may strengthen and organize into a ring of thunderstorms - an outer eyewall - that slowly moves inward and robs the inner eyewall of its needed moisture and angular momentum.

Key term(s)
  • inner eye wall
  • internal eye wall

French

Domaine(s)
  • Physique de l'atmosphère
CONT

Quand l'œil intérieur se forme, la convection qui entoure le mur de l'œil peut s'organiser en anneaux distincts. En fin de compte, l'œil intérieur commence à sentir les effets de la subsidence qui résulte du mur de l'œil externe, et le mur de l'œil intérieur s'affaiblit, pour être remplacé par le mur de l'œil externe.
