A pressão intra-ocular elevada pode sustentar por pelo menos por três meses após o tratamento a laser em primeiro lugar. Este modelo do rato da pressão intra-ocular elevada fornecem oportunidades valiosas para estudar os mecanismos de pressão induzida pela perda de células ganglionares da retina e lesão do nervo óptico que imitam a mudança patológica em humanos glau...

laser-induced chronic ocular hypertension model on sd rats

<p class="jove_content">Glaucoma é uma das principais causas de cegueira no mundo. Pressão intraocular elevada é um importante fator de risco. Fotocoagulação a laser hipertensão ocular induzida é um dos modelos animais bem estabelecidos. Este vídeo demonstra como para induzir hipertensão ocular por fotocoagulação com laser de argônio em ratos.</p>
