My 6yr old son has NF1. Yesterday he had his annual eye care exam at the Opthamologist. The md discovered that his vision has for the second time had a slight decrease in visual acuity in one eye. When the md corrected the vision, my son's clarity was still the same/not improved. The md stated the reason could be lazy eye (amblyopia). Or, that the cause could potentially be a optic glioma and that a MRI may be necessary. The md discussed first treating the issue with glasses and/or patching, taking a non-invasive approach to see if that improves the vision. My question is, for those of you with children who have had optic gliomas, did your children have any visual symptoms such as lazy eye (amblyopia) or any other optical symptoms?
