Evaluation of 0.01% Hypochlorous Acid Eye Drops Combined with Conventional Treatment in the Management of Fungal Corneal Ulcers: Randomized Controlled Trial

PurposeTo evaluate the efficacy and safety of hypochlorous acid (HOCI) eye drops in the treatment of fungal keratitis.MethodsA total of 96 patients (96 eyes) with fungal keratitis were randomly divided into two groups: group & UIota; (conventional treatment + topical HOCI eye drops); The group II (conventional treatment). According to its severity, those patients were divided into grade & UIota; or grade II. Use of fungal scraping and culture to identify the type of fungal infection, slit lamp examination, and corneal fluorescein staining to observe regression, and confocal corneal microscopy to assess fungal mycelial changes. The main outcome measures were the success rate, healing time, visual recovery, and complications. The Kaplan-Meier curve method was used to analysis of the survival function of days to cure between the two groups.ResultsThere were no statistical differences between the two groups in terms of general condition, medical history, and grading. Corneal scraping results showed that all patients had filamentous fungi. For grade & UIota; patients, all patients were cured, and the patients in Group I showed faster healing speed than that in Group II (t = -3.665, p < .01). For grade II patients, the recovery time (t = -4.121, p < .01) and the disappearance of hypopyon (t = -4.291, p < .01) were significantly faster in the combination group. In grade & UIota; and II patients, the final visual acuity and the incidence of complications such as corneal neovascularization, cataract, and hyphema showed no differences in both groups. The survival curve showed that the healing rate of ulcers in the combination treatment group was faster than that in the conventional treatment group (& chi;(2) = 14.332, p = .001).ConclusionHOCI can accelerate the healing of fungal keratitis without obvious complications, indicating a promising future in the field of keratitis treatment.
