Scanning laser polarimetry determined retinal nerve fibre layer thickness Baseline, 6 and 12 months [clinicaltrials_resource:2c00d389a92564d09318761caa8ffc95]

The primary outcome will be difference in retinal nerve fibre thickness at 6 months between affected eye and non-affected fellow eye at baseline between the amiloride and placebo group. An additional measure will be made at 12 months
