[Glial hamartoma of the papilla]
Abstract:
There are shown two cases of glial hamartoma of the optic nerve head. In both cases the retinal vessels are tortuous around the optic nerve disc, and the choroid shows a brown colour, like a choroidal naevus. Histologically this kind of tumors of the optic nerve head are astrocytomas and they are met specially under the age of twenty. The glial hamartoma of the optic nerve head is a rare disease.

Overview
Nervous Tissue: Glial Cells
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial cells that interact...
