BACKGROUND: To report the treatment outcomes of mycotic keratitis with collagen cross-linking.
DESIGN: Retrospective study.
PARTICIPANTS: Patients with smear-positive moderate mycotic keratitis.
METHODS: A retrospective case-file analysis was performed to identify cases of moderate mycotic keratitis treated with and without additional collagen cross-linking, in addition to intensive topical antifungal therapy. Patients in which collagen cross-linking was performed on the day of presentation (group 1) were compared with patients who received medical treatment alone in the form of 5% natamycin eye drops (group 2).
MAIN OUTCOME MEASURES: The primary outcome measure was the time taken for resolution of infection.
RESULTS: Overall, 41 cases were included for analysis (group 1, 20 cases; group 2, 21 cases). Mean age of the patients was comparable in both groups (46.5 ± 17.01 vs. 41.2 ± 20.7 years; P = 0.36). Average infiltrate size was 16.35 ± 6.8 mm(2) in group 1 and 17.09 ± 7.4 mm(2) in group 2 (P = 0.83). Overall, Aspergillus was the most commonly isolated organism (n = 4 group 1; n = 6 group 2). Resolution of infection was observed in 18 cases (90%) in group 1 and 18 (85.71%) cases in group 2. The average healing time was 30.85 ± 26.6 days in group 1, while it was 31.28 ± 19.97 days in group 2 (P = 0.94). Final best-corrected visual acuity in group 1 was 1.13 ± 0.55 and 1.25 ± 0.46 in group 2 (P = 0.46). A tectonic keratoplasty was performed in two cases in group 1 and three cases in group 2 (P = 1.00).
CONCLUSIONS: In our study, additional collagen cross-linking treatment did not have any advantage over medical management in cases with moderate mycotic keratitis.
