PRIMARY outcome

Timeframe: Measured at 8am 10 am and 4 pm at Baseline and on Days 15, 42 and 84

Population: The Per Protocol population was the primary efficacy population and consisted of those subjects in the ITT population who had no major protocol violations and no missing data points

SECONDARY outcome

Timeframe: Baseline and 84 days

Population: Safety population defined as all randomized subjects who received at least one dose of the allocated study medication.

Visual Acuity was measured using the Corrected Snellen Visual Acuity method reported as the Logarithm Minimum Angle of Resoution (logMAR) change from baseline. The Snellen eye chart was used with the subject's current corrected lens prescription at a distance equivalent to 20 feet. Results from the Snellen chart were converted to the logMAR scale which is the standard tool for reporting visual acuity outcomes.

SECONDARY outcome

Timeframe: Baseline and 84 days

Population: Safety population defined as all randomized subjects who received at least one dose of the allocated study medication.

Number of participants with eye abnormalities following ophthalmoscopy. Direct ophthalmoscopy with dilation included assessment of the optic nerve head for pallor and cupping. A dilated fundus examination consisting of the vitreous, optic nerve, macula, and peripheral retina was conducted. Results are reported as the number of subjects with clinical significant abnormalities at Day 84 that were not clinically significant at Baseline.

Visual Field was performed using an automated perimeter according to the sites standard protocol. This test measures the angle of the visual field from the central visual axis. Visual Field Testing generates a numerical scale as its main result which shows the retinal sensitivities at the different test locations, expressed in Decibels (dB). The mean deviation in the visual field reflects the overall depression (deviation from normal values). Negative values indicate a reduction in visual field. The analysis performed is the mean change from baseline at Day 84.
