结局指标
主要结局
Mean Circumlimbal Conjunctival Staining Score
时间窗: 1 week
Circumlimbal conjunctival staining was expressed as the sum of the individual scores observed across all of the evaluated regions of the eye. The bulbar conjunctiva was assessed by the investigator utilizing a slit-lamp and lissamine green ophthalmic dye. Staining coverage was scored separately in each of four regions (nasal, temporal, inferior, and superior) using a 4-point clinical grading scale (grade 0-3), where Grade 0 = No staining present; Grade 1 = Slight staining present; Grade 2 = Moderate staining present; and Grade 3 = Dense staining present. The scores for the four regions were summed, with a sum score range of 0-12. A lower score represents a more desirable outcome.
