AMD = age-related macular degeneration; SD = standard deviation.
Data are expressed as number of eyes (number of patients).
A few patients had unilateral pseudophakia and had both eyes enrolled, so the patient totals may add to greater than the actual number enrolled.
Some patients had unilateral exudative AMD and had both eyes enrolled, so patient totals add to greater than the actual number enrolled.
