Contact lens induced papillary conjunctivitis
BID for 8 weeks, with lens wear stopped for the first 4 weeks, as dosed in the trial
RCT · n=85 · no placebo arm
Randomized, double-masked three arm trial in 85 soft lens wearers (170 eyes) with mild to moderate papillary conjunctivitis comparing this concentration, fluorometholone 0.1%, and both: reductions in redness, itching and tearing and the gain in lens tolerance were comparable across arms, olopatadine beat fluorometholone for redness at 8 weeks (P=0.01), and IOP rose significantly with fluorometholone (P=0.003). No placebo arm, and the authors ranked the combination first, olopatadine alone second, fluorometholone alone third. The report gives frequency and duration but not the number of drops per dose.
Vernal keratoconjunctivitis
BID for 8 weeks, as dosed in the trial
Open-label comparative · n=50
Open-label comparative study, randomized per the authors, in 50 children aged 5 to 15 against bepotastine besilate 1.5% BID: both arms reduced signs and symptoms and were equally effective on itching, bepotastine gave quicker relief of watering, discomfort and hyperemia while olopatadine improved papillary hypertrophy faster, and the authors state the between-drug difference was not statistically significant. No placebo arm, single center, and PubMed indexes it as a journal article rather than a randomized controlled trial. The report gives frequency and duration but not the number of drops per dose.
