Abstract:
Visual function in early age-related macular degeneration (AMD) were observed by contrast sensi-tivity(cs), macular threshold, FM 100-Hue test, dark adaptation, and the Amsler grid. All patients with early AMD achieved corrected visual acuity of 1.0 or better. The results revealed that early AMD showed one or more of following: abnormal macular light sensitivity (MLS), hue discripmination, CS, threshold of dark adaptation, and Amsler grid, comparing with those of the normal controls. These tests proved useful for the early diagnosis of AMD, and their sensitivity was found to be in the following descending order: MLS, FM100-hue, CS, and Amsler grid.
