Ocular Assessments include: Afterinformed consent process, completion of all screening assessments and once allthe inclusion/exclusion criteria are met, the eligible subjects shall beenrolled into the study. Demographics, Medical and surgical history shall berecorded during screening visit. Details of concomitant medications and adverseevents if any shall be recorded during each visit. Physical examination shallbe done during screening and each successive visit. Vital signs shall bemeasured on each visit and Lab parameters will perform. Ocular Assessmentsinclude: Mesopic, high contrast DCNVA and Photopic, high contrast DCNVAfor each eye and binocularly will be assessed at Screening, Days 1, 14, and 30with time in-travels.
