 (submitted: June 4, 2014)
Mean Annualized Lesion Enlargement Rate From Baseline as Assessed With Fundus Autofluorescence Imaging [ Time Frame: Baseline, up to Month 30 ]
The size of the retinal lesion was measured using the Heidelberg Retinal Angiography system at Baseline, Month 6, Month 12, Month 15, Month 18, Month 24, and Month 30. Images were collected in both eyes; however, one eye from each subject was chosen as the study eye, and only data for the study eye were used for the efficacy analysis. Results were estimated from a longitudinal random effects regression model. A greater lesion growth rate may indicate a faster progression of the disease.
