Long-Term Follow-up of Fixation Patterns in Eyes With Central Scotomas From Geographic Atrophy That Is Associated With Age-Related Macular Degeneration

To study whether fixation patterns changed over time in patients with central scotomas from geographic atrophy from age-related macular degeneration. Prospective cohort study. setting: Institutional. patient or study population: Prospective natural history study of geographic atrophy included 34 eyes of 25 patients with baseline acuity between 20/80 and 20/200 and with subsequent follow-up. observation procedures: Baseline and annual follow-up visits included best-corrected visual acuity, scanning laser ophthalmoscope macular perimetry, reading rate, and clinical evaluation. main outcome measures: Location of eccentric preferred retinal locus for fixation (PRL). At baseline, 77% of study eyes had a PRL. At the final visit (median follow-up, 5.3 years), 91% of study eyes had a PRL, with 81% of the eyes retaining the baseline PRL location. Fixation with the scotoma to the right and fixation with the scotoma superior were the first and second most common fixation patterns, respectively. Reading rates of
