Retinoblastoma treatment by cryotherapy / photocoagulation in Marrakech

Ophthalmologist

It is a retinal tumor which, if left untreated, detaches the retina and gradually destroys vision. It is then likely to develop towards the orbit, towards the optic nerve and the brain, even to disseminate in the organism, thus engaging the vital prognosis. It is a tumor of genetic origin. For the tumor to grow, two mutations in the same gene, located on chromosome 13 are necessary. - Diode laser thermotherapy: It consists of applying the laser beam to the tumor until a sufficient rise in temperature with bleaching. - Cryotherapy: It consists of freezing the tumor several times by checking at the fundus that the ice ball covers the tumor well. The temperature should drop to -60 ° to -80 °
