A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect. Medical or scientific judgment should be exercised in deciding whether reporting is appropriate in other situations. Refer to the General Adverse AE/SAE module for a complete list of AEs and SAEs.

Per LOC III, NC ranges from 0.1 (clear or colorless) to 6.9 (very opaque or brunescent). Change from Baseline was calculated as the value at the post-Baseline time point minus the value at Baseline.
Change From Baseline in the Logarithm of the Minimum Angle of Resolution (LogMAR) Visual Acuity at Week 28 and Week 52	Baseline; Week 28 and Week 52	Visual acuity is defined as the acuteness or clearness of vision. The minimum angle of resolution (MAR) is the angle a viewed object subtends at the eye, usually stated in degrees/minutes of arc. Visual acuity was measured using Early Treatment Diabetic Retinopathy Study (ETDRS) charts in decimal numbers. The LogMAR scale is used to express the visual acuity in a linear scale as the logarithm to base 10 of the MAR.
