Abstract

PURPOSE: To examine the added predictive value of microperimetric sensitivity and low luminance deficit (LLD; difference between photopic and low luminance visual acuity (VA)) to information from colour fundus photography (CFP) for progression to late age-related macular degeneration (AMD) in individuals with bilateral large drusen. METHODS: 140 participants with bilateral large drusen underwent baseline microperimetry testing, VA measurements and CFP. They were then reviewed at 6-monthly intervals to 36 months, to determine late AMD progression. Microperimetry pointwise sensitivity SD (PSD), LLD and the presence of pigmentary abnormalities on CFPs were determined. Predictive models based on..
