PURPOSE: To report a patient recovering vision after three-dimensional conf
ormal radiotherapy for optic nerve sheath meningioma.
METHODS: Radiotherapy was delivered by a three-dimensional-conformal techni
que in 28-180 cGy fractions.
RESULTS: Visual acuity improved from 20/200 to 20/30, and the:visual field
defect resolved.
CONCLUSION: Visual loss from optic nerve sheath meningioma can be reversed
by three-dimensional conformal radiotherapy. (C) 2000 by Elsevier Science I
