To the Editor.
—We would like to emphasize a point made by Dr Kushner1 in the May 1984 issue concerning functional amblyopia associated with optic nerve glioma. We recently encountered a patient with decreased visual acuity and a presumed optic nerve glioma. Occlusion therapy resulted in a marked improvement of visual acuity.
Report of a Case.
—A 20-month-old infant with neurofibromatosis was seen for an intermittent right exotropia that was first noted several months prior to our examination. He had been otherwise healthy, except for mild developmental delay. The examination revealed a strong visual preference for the left eye. A variable right intermittent exotropia of 25 to 30 prism diopters was present. Cycloplegic refraction was +1.00+0.25×80 OD and +2.50+0.75×180 OS. Several small neurofibromas were present on the skin of the left medial canthus and left upper lid. The remainder of the examination results were normal. The patient was given
