The Change in Corneal Surface Staining as Measured by Rose Bengal Dye Staining
Time Frame: Between baseline and at 8 weeks of treatment
|
Corneal staining score as measured by Rose Bengal (RB) dye staining using National Eye Institute (NEI) 1995 workshop grading scale.
The dye was applied to each eye and a slit lamp was used to observe corneal staining.
The NEI scale relies on a chart that divides the cornea into 5 sections and assigns a value from 0 (absent) to 3 (severe) to each section, based on the density of punctate staining, final staining score being the sum of individual section scores, for a range of 0 (minimum) -15 (maximum) points.
Complete corneal staining clearance with RB dye defined as a score of 0 indicating the best outcome.

Between baseline and at 8 weeks of treatment

The Change in the Ocular Surface Disease Index Score
Time Frame: Between baseline and at 8 weeks of treatment
|
Ocular Surface Disease Index (OSDI), a 12-item questionnaire, assesses symptom of ocular irritation in dry eye disease (DED) and how it affects functioning related to vision in the past week.
It has 3 subscales: ocular symptoms, vision-related function, and environmental triggers.
Patients rate their responses on 0 to 4 scale with 0 being "none of the time" and 4 being "all of the time."
OSDI score range from 0-100 with score 0-12 being normal, 13-22 being mild DED, 23-32 being moderate DED, and >33 being severe DED.
OSDI=[(sum of scores for questions answered)×100]/[(total questions answered)×4]

The Change in Mucoid Debris Strands Between Baseline and 8-weeks
Time Frame: Between baseline and 8-weeks of treatment
|
The presence of mucoid debris/strands over the ocular surface was assessed and the amount graded as the absence of mucoid debris (0) or presence of mucoid debris (1+, 2+ or 3+) with a bigger number indicating greater presence of mucoid debris with "3+" implying presence of the highest amount of mucoid debris and indicating the worst outcome.
