Comparative in vitro efficacy of ivermectin, lotilaner, lime sulfur, tea tree oil, and lemongrass oil against Demodex folliculorum. (PubMed, Cont Lens Anterior Eye) - "Lotilaner ophthalmic solution 0.25% demonstrated the shortest median survival time, followed closely by ivermectin 1% and lemongrass oil. While lemongrass achieved complete mite mortality most rapidly, lotilaner was most consistent in reducing survival time. These in vitro findings suggest that both pharmaceutical and natural agents may possess promising acaricidal activity. Further in vivo studies are warranted to confirm these findings and explore safety and clinical applicability."

Pediatric blepharokeratoconjunctivitis: review of epidemiology, pathophysiology, and current treatments. (PubMed, Curr Opin Ophthalmol) - "Pediatric blepharokeratoconjunctivitis is a chronic inflammatory condition affecting the eyelids, conjunctiva, and cornea. It is underdiagnosed and associated with significant vision-threatening complications. While there is no established consensus on the most effective therapeutic strategy, management currently includes lid hygiene, topical/systemic antibiotics, corticosteroids, immunosuppressants, lubricants, and dietary supplements. Challenges arise from its chronicity, recurrence, and lack of standardized treatment protocols. This underscores the importance of early diagnosis, education, and continued research on treatment methods to prevent severe outcomes."
