[Hemangiomas of the optic nerve head].

The article presents five cases of various forms of hemangiomas of the optic nerve head (ONH) and juxtapapillary retina that were monitored and analyzed using ocular visualization methods. The obtained data allowed a conclusion that capillary hemangioma of the ONH features clearly-seen boundaries of the lesion both on ophthalmoscopy and optical coherence tomography (OCT) images; on the other hand, juxtapapillary granuloma can be characterized by blurred outlines on ophthalmoscopy and a gradual transition of the altered retina on OCT images with secondary changes seen in the macular area. When comorbid, capillary hemangioma of the ONH and retina feature a combination of these visualization signs.
