AIM: To evaluate the efficacy of topical administration Natamycin, which is produced by China, in an experimental rabbit model of Fusarium solani keratitis, to provide experimental basis for the application of clinical safety. · METHODS: Fusarium solani was induced in the right eye of 30 New Zealand rabbits. Forty-eight hours after inoculation, the animals were divided into 3 different treatment groups, 10 rabbit eyes of each group: Group 1 (Natamycin) treated with topical Natamycin, group 2 (Natacyn) treated with topical Natacyn, group 3 (control) treated with topical saline solution. The eyes of each group was examined clinically with slit lamp using ulcer scoring system on day 4, 10, 15, and 21 for status of healing, corneal vascularisation, iritis, hypopyon and macular nebula. The findings were recorded on day 10 and day 21. · RESULTS: Ulcer score on day 10, day 15, day 21: The score of Natamycin group are 1.45±0.16, 1.08±0.11, 0.70±0.40. The score of Natacyn group are 1.35±0.12, 1.10±0.12, 0.65±0.35. the score of control group are 1.30±0.08, 3.63±0.28, 3.80±0.16. Natamycin group and Natacyn group were different from control group(P <0.01). There is no difference between Natamycin group and Natacyn group. Status of healing on day 10 and day 21: The cure rate of the Natamycin group is 90% on day 10, and 100% on day 21. The cure rate of the Natacyn group is 80% on day 10, and 100% on day 21.Natamycin group and Natacyn group were different from control group (P <0.01). There is no difference between Natamycin group and Natacyn group. Corneal vascularisation, iritis, hypopyon and macular nebula on day 10 and day 21: in Natamycin group, the number of the eyes which have Corner vascularisation, iritis, hypopyon and macular nebula are 2,0,0,2. In Natacyn group, the number of the eyes which have Corner vascularisation, iritis, hypopyon and macular nebula are 1,0,0,2. In control group, the number of the eyes which have Corner vascularisation, iritis, hypopyon and macular nebula are 9,9,8,9.Natamycin group and Natacyn group were different from control group (P< 0.01). There is no difference between Natamycin group and Natacyn group. · CONCLUSION: Natamycin was found to be effective in fungal keratitis, similar to Natacyn, and it can stop the corner vascularisation, iritis, hypopyon and macular nebula to happen. Natamyin manufactured in China is effective against fungal keratitis, with esay availability and low toxicity in its use.
