Abstract
Purpose
We prospectively investigated clinical changes and long-term outcomes after administration of the drugs recommended by the Age-Related Eye Disease Study-2 to patients with intermediate age-related macular degeneration (AMD).
Methods
This prospective multicenter study enrolled 79 eyes of 55 patients taking lutein and zeaxanthin. The primary endpoint was contrast sensitivity; this was checked every 12 months for a total of 36 months after treatment commenced. The secondary endpoints were visual acuity, central macular thickness, and drusen volume; the latter two parameters were assessed using spectral domain optical coherence tomography.
Results
The mean patient age was 72.46 ± 7.16 years. Contrast sensitivity gradually improved at both three and six cycles per degree. The corrected visual acuity was 0.13 ± 0.14 logMAR and did not change significantly over the 36 months. Neither the central macular thickness nor drusen volume changed significantly.
