Efficacy Profile of Intracameral Amphotericin B. The Often Forgotten Step.

Abstract

The objectives of this study were to assess visual and structural outcomes in mycotic keratitis after conventional treatment (topical and systemic antifungals) and intracameral amphotericin B (ICAMB), and to evaluate any complications. This was a prospective, nonrandomized, nonblinded interventional study. This study was conducted on 104 eyes of 104 patients with fungal corneal ulcers. Patients were categorized into 2 groups: group A, who received conventional topical and systemic antifungal medications, and group B, who received ICAMB in the dose of 5 to 10 μg in 1 mL of 5% dextrose. Response to treatment was evaluated. Results of the 2 groups were compared with appropriate statistical indices. The mean final visual acuity in patients in group B receiving ICAMB was 1.22 ± 0.31 logMAR units. The improvement in mean visual acuity was 1.40 ± 0.2 logMAR units. In group A, mean visual outcome was 1.25 ± 0.73 logMAR units. There was an improvement by 0.55 ± 0.30 logMAR units. Healing with varying degrees of opacification occurred in a significant number of patients (81.48%) treated with ICAMB as compared with conventional treatment (Z = 2.24, P < 0.05). Complications, such as sloughing, occurred in significantly fewer patients treated with ICAMB as compared with conventional treatment (Z = 2.29, P < 0.05). In cases of keratomycosis where response to local and systemic antifungal treatment is not evident after 7 days, ICAMB can be safely administered to prevent the progression of ulcers and the development of complications.
