<p> Na twee laser behandelingen met 7 dagen na elkaar, kunnen we verhogen de IOD van laser photocoagulated ogen met 50% vergeleken met controle oog. De verhoogde IOP kan houden voor tenminste 3 maanden na de eerste laserbehandeling. Deze rat model van verhoogde intra-oculaire druk waardevolle kansen om de mechanismen van druk-geïnduceerde retinale ganglion cel verlies en schade aan de oogzenuw die de pathologische veranderingen in de menselijke glaucoom na te bootsen te bestuderen. </p>

laser-induced chronic ocular hypertension model on sd rats

<p class="jove_content">Glaucoom is een van de belangrijkste oorzaken van blindheid in de wereld. Verhoogde intraoculaire druk is een belangrijke risicofactor. Laser fotocoagulatie veroorzaakte oculaire hypertensie is een van de gevestigde diermodellen. Deze video laat zien hoe oculaire hypertensie te induceren door Argon laser fotocoagulatie in de rat.</p>
