• The visual field test results from 20 patients with cone-rod degeneration (CRD) from all inheritance patterns were reviewed. Typical fundus findings of CRD included optic disc pseudoedema, temporal disc atrophy, parapapillary and disc telangiectasias, and few to no retinal pigmentary deposits. Visual field changes were seen to be distinctive and, like electrophysiologic tests, were helpful in pointing to a retinal degenerative process rather than an optic neuropathy.
