Omega-3 Supplementation vs Demodex vs Eyelid Cleanser for Pediatric Chalazia

Participants enrolled into the study will be prescribed twice daily warm compresses for 8 weeks and randomly allocated (1:1:1) to receive either 1) Oral omega-3 supplementation and standard eyelid cleanser, 2) Anti-Demodex eyelid cleanser, or 3) Standard eyelid cleanser as treatment for chalazia. Participants will return for a visit after 8 weeks for a masked clinical exam to determine whether the chalazia has improved or resolved. The 8-week visit will also include a masked central reader's assessment of parent photographs, parental palpation of eyelids, and review of Parental Treatment Outcome Question as part of a telehealth objective. After the 8-week visit, treatment is at investigator discretion other than 1) the OMEGA-3 group must continue the study-prescribed omega-3 supplementation and 2) the ANTI-DEMODEX and STANDARD groups must not receive omega-3 supplementation. Participants will be followed from 8 weeks to 12 months from baseline to determine the proportion of participants with new chalazia based on monthly parental report and office visits at 6 months and 12 months.
