Objectives
Narrative objectives1
Angle will be observed by gonioscope and GS-1 for cases which require gonioscopy. Lens is placed/device is docked on the eye then chamber angle will be photographed from 8 directions, then the time required to take off the lens/device will be measured. Also, NRS score will be written in questionnaire after gonioscopy by gonioscope and GS-1. Concordance rate of gonioscopy by gonioscope and angle photograph by GS-1 will be evaluated. Angle evaluation by anterior OCT will also be compared. Also, outflow reconstruction will be categorized into complete response and resistant, and it will be evaluated to find any characteristics in each angle observation.
