Other: No Treatment
No Treatment was given in this study.
- Anterior Angle Width Using Anterior Segment Optical Coherence Tomography (AS OCT) [ Time Frame: Day 1 ]The angle width formed between the eye's cornea and iris in both eyes was measured in microns (µm) using AS OCT, a laser-based, noninvasive, diagnostic system providing high-resolution images of the eye.
- Number of Study Eyes in Each Shaffer Grade Using Gonioscopic Lens [ Time Frame: Day 1 ]The angle width formed between the cornea and iris in both eyes was measured by gonioscopy using Shaffer grading where: grade 4=wide open, grade 3=moderately open, grade 2=moderately narrow, grade 1=very narrow or grade 0=closed. The number of eyes in each Shaffer Grade is reported.
- Number of Study Eyes in Each Step Grade Using Gonioscopic Lens [ Time Frame: Day 1 ]The angle width formed between the cornea and iris in both eyes was measured by gonioscopy using Large Step Grading ranging from 1.0 (smallest angle width) to 7.5 (largest angle width) with 0.5 unit intervals where each Large Step unit represented a fixed length of approximately 200 µm. The number of eyes in each Large Step Grade is reported.
