“The text contains 146 color illustrations, many of which are fundus photographs. These are uniformly excellent. As to be expected, a number of CT Scans and MRI scans are included as well. This is a remarkable book. It is a text that should be included in every Neuro-Ophthalmologist’s library … .” (Walter M. Jay, Neuro-Ophthalmology, 2017)
