Sign: Corneal Fluorescein Staining Score
大体时间:change from baseline to week 4
|
The staining was graded with the Ora Calibra® Corneal and Conjunctival Staining Scale. The ocular surface was divided into three regions, including superior, central and inferior region. The following scale was used to grade staining of the each region. Half (0.5) grade increments may be used. The total score of corneal fluorescein staining was calculated as the sum of three regions, the score range is 0 (minimum) to 12 (maximum). None 0 = no staining Trace 1 = occasional Mild 2 = countable Moderate 3 = uncountable, but not confluent Severe 4 = confluent |

Symptom: Ocular Discomfort Score
大体时间:change from baseline to week 4
|
Ocular discomfort scores was subjectively graded by the subjects according to the following Ora Calibra® Ocular Discomfort Scale, rating each eye separately, the score range is 0 (minimum) to 4 (maximum). 0 = no discomfort

Tear Film Break-up Time
大体时间:change from baseline to week 4
|
The examiner was instilled 5 uL of 2% preservative-free sodium fluorescein solution into the inferior conjunctival cul-de-sac of each eye.
With the aid of a slit-lamp, the examiner monitored the integrity of the tear film, noting the time (seconds) it takes to form micelles from the time that the eye is opened.

Conjunctival Redness
大体时间:change from baseline to week 4
|
Conjunctival redness was graded according to the following scale: Half (0.5) unit increments may be used. None 0 = Normal, without vasodilation Trace 1 = Trace ciliary or conjunctival vasodilation Mild 2 = Broad ciliary vasodilation; Moderate 3 = Broad ciliary and slight, horizontal conjunctival vasodilation Severe 4 = Broad ciliary and prominent, horizontal conjunctival vasodilation |

Ocular Surface Disease Index (OSDI)©
大体时间:change from baseline to week 4
|
OSDI scores was subjectively graded by the subjects according to the Ocular Surface and Disease Index (OSDI) Scale.
Patients scored each question from 0 to 4 (higher score means more severe), and the OSDI score is the sum of total 12 questions.
The score range is 0 (minimum) to 48 (maximum).
