Abstract

A 11-year-old boy with congenital microphthalmos of the right eye presented with gradual protrusion of his ocular prosthesis. MRI showed an orbital mass adjacent to the microphthalmic eye. After removal of the eye and the orbital soft tissue mass a gliotic mass, resembling a pilocytic astrocytoma WHO grade 1 (glioma) was diagnosed. Through a colobomatous cleft in the eye the tumour spread in the orbit. There were no clinical signs of neurofibromatosis 1. This case showed a very rare association between a microphthalmic and colobomatous eye and pilocytic astrocytoma, grade 1. However a far advanced and infiltrative massive retinal gliosis cannot be definitively excluded as differential diagnosis.

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
