A new self-adjustable glaucoma valve
Résumé
Introduction: Glaucoma, the leading cause of irreversible blindness globally, affects more than 70 million people across the world. When initial treatments prove ineffective, especially for cases with high intraocular pressure (IOP), the preferred approach involves employing glaucoma drainage devices (GDDs). Methods: This study introduces a novel self-adjustable glaucoma drainage device (SAGDD) designed to maintain IOP within the desired biological range (10 mmHg < IOP

Glaucome
Le glaucome est une maladie dégénérative du nerf optique qui entraîne une perte progressive de la vision commençant tout d'abord en périphérie et progressant graduellement vers le centre. Cette maladie est souvent associée à une pression intraoculaire (PIO) élevée qui comprime et endommage les fibres du nerf optique et de la rétine. Dans d'autres cas, malgré une PIO normale, une circulation sanguine inadéquate entraîne la mort (nécrose) des cellules du nerf optique et de la rétine.
Tension oculaire
La tension oculaire (également appelée pression intra-oculaire ou PIO ; en anglais, Intraocular pressure ou IOP) correspond à la pression régnant à l'intérieur du globe oculaire, qui est un organe creux. Sa mesure physique, dans le cadre de l'ophtalmologie, est la tonométrie. Cette tension, souvent confondue avec la tension artérielle, n'a pourtant aucun rapport avec cette dernière qui correspond à la pression sanguine régnant à l'intérieur des artères.
Intraocular lens
An Intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness, a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or false lens). Both kinds of IOLs are designed to provide the same light-focusing function as the natural crystalline lens. This can be an alternative to LASIK, but LASIK is not an alternative to an IOL for treatment of cataracts.
