Purpose: The aim of the study was to report the occurrence of contamination/replacement of ophthalmic eye drops with liquids of acidic nature in patients treated for nonresponding scleritis. Methods: This was a retrospective interventional case series study. Results: Of the three patients (4 eyes) referred as necrotizing scleritis, two were found to have acid as the content in the bottle/s being used as eye drops, confirmed using biochemical tests. All four eyes had tarsal ischemia and tarsal conjunctival defect in addition to severe scleral ischemia involving the inferior bulbar area. All four eyes required tenonplasty with amniotic membrane transplant more than once for the ocular surface to heal. Two of the three patients were on systemic immunosuppressives including pulse cyclophosphamide for refractory necrotizing scleritis. Sulfuric and hydrochloric acid was isolated from the bottles of 2nd and 3rd patient using confirmatory biochemical tests. Conclusion: It is important to be aware of the possibility of contaminating or replacing contents of eye drops with harmful agents of acidic nature and should be considered in situations that resemble the clinical picture described herein.
