The patient reported exposure to plant debris while performing yard work and also water exposure while cleaning his coral fish tanks. Clinical examination revealed bilateral epitheliopathy progressing to frank epithelial defects with underlying stromal necrosis 6 days after exposure. Empiric topical antibiotic drops were initiated, but multiple cultures, corneal biopsy, and confocal microscopy were all negative for an infectious agent. Over a 2-week period, the epithelial defects worsened and a suspicion for a toxic etiology was raised. The patient later recalled rubbing his eyes after exposure to Epipremnum aureum (Golden Pothos/Devils Ivy) sap. He was thus treated conservatively with artificial tears, topical corticosteroids, and amniotic membrane. After 3 months, the epithelial defects resolved, but with corneal scarring, prominently in the left eye and underwent penetrating keratoplasty. Five years after presentation, best-corrected visual acuity with hard contact lenses was 20/25 in the right eye and 20/20 in the left eye.\u0000\u0000\u0000CONCLUSION\u0000Epipremnum aureum toxicity is a rare cause of keratitis.

Clinical and microbiological tests were repeated at each visit. Changes and correlations were examined.\u0000\u0000\u0000RESULTS\u0000Symptomatic lens wearers had a higher ratio for the number and frequency of gram-positive rods and cocci. Microblepharon exfoliation reduced the number and ratio of gram-positive rods to cocci from baseline for symptomatic wearers that lasted 7 to 10 days after treatment (P<0.05). Numbers of bacteria, the ratio of rods to cocci, and lipase activity correlated with lash contamination (r≥0.385; P≤0.046) and anterior blepharitis (r≥0.359; P≤0.048). Bacterial lipase correlated with meibomian gland secretions (r=0.422; P=0.038) and the tear evaporation rate (r=0.479; P=0.022). Microblepharon exfoliation produced a significant reduction in CLDEQ-8 scores and converted 10 symptomatic into asymptomatic lens wearers.\u0000\u0000\u0000CONCLUSIONS\u0000There was dysbiosis in the lid microbiome of symptomatic lens wearers. Microblepharon exfoliation reduced the number, frequency of isolation, and ratio of gram-positive rods and cocci. Bacterial numbers and their lipase production correlated with changes to clinical signs and symptoms. Symptomatic lens wearers could be converted to asymptomatic lens wearers after microblepharon exfoliation.","PeriodicalId":12216,"journal":{"name":"Eye & Contact Lens: Science & Clinical Practice","volume":"116 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85503073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
