RESUMO
Mammals have developed almost perfect functional adaptations of their eyes, central visual system and oculomotor system for high resolution and stable vision. This performance is subserved by stabilizing reflexes like the optokinetic and the vestibular ocular reflex. Visual information about retinal image slip is relayed through the nucleus of the optic tract in the pretectum and the terminal nuclei of the accessory optic system to the visual motor system. Retinal and more importantly cortical information is integrated in these nuclei to optimize visual control of gaze stabilization during ego-motion.

The persistent müllerian duct syndrome represents a rare form of male pseudohermaphroditism secondary to anti-müllerian hormone deficiency. We describe 2 cases of phenotypically male postpubertal patients with a uterus and tubes. Both patients presented with bilateral cryptorchidism, 1 was seen for gynecomastia and 1 was seen for an abdominal mass that was found to be a testicular tumor.
