Abstract
Diagnosis of deep optic disc drusen (OND) in children is difficult because they are not visualized ophthalmoscopically and often mimic a picture of stagnation, identifying the wrong tactics diagnostic and therapeutic actions.
Materials and Methods: Children who ophthalmoscopically revealed prominence and blurring of the optic disk with a comprehensive survey includes an ultrasonic scanning of the eyeball and orbit, optical coherence tomography (OCT) and retinal optic disc, computer perimetry, electroretinography (ERG) and the registration of visual evoked potentials (VEP).
Results and discussion: Optic disc drusen is diagnosed by ultrasound scan that leds to prominence disk. No changes perineural space allowed excluding stagnation and avoiding the need for complex and invasive methods. OCT allows locating drusen, and assessing the degree of prominence disc and peripapillary retinal condition. The degree of functional disorders of the optic disc and retina, correlated with the volume and topography of the drusen. Drop of electrophysiological parameters (neuroglial index and amplitude oscillatory potentials) and increased light sensitivity of the retina of depression (from the expansion of the «blind spot» to a generalized depression with lots of scotomas) depend on the volume, the depth of druses and their proximity to the vascular bundles, characterizing the degree of compression glial tissue of the optic disc and hemodynamic disturbances.
Conclusions: The proposed algorithm of examination of patients with optic disc drusen can not only establish the fact of presence of drusen, but also to determine their exact location, assess the severity of morphological and functional changes, determining the prognosis of the disease.
