Combined non-steroidal therapy in experimental corneal injury.
The effects of anti-inflammatory non-steroidal therapy combined with free-radical scavengers were studied and compared to corticosteroid use in the treatment of experimental corneal injury.. Eighty New Zealand albino rabbits were used in this study. A corneal alkali burn was induced by applying 1-N NaOH filter paper on the central axis of the right cornea for 30 s. Animals were distributed into five treatment groups: group 1 (control group) was only given gentamicin; group 2 was treated with 0.5% dimethylthiourea (DMU); group 3 received 1% dexamethasone; group 4 was given combined 0.5% DMU and 1% indomethacin; group 5 was treated with 0.5% DMU and 0.1% diclofenac sodium. One 50-microliter drop of gentamicin was instilled every 12 h, whereas the other drugs were instilled every 6 h (50 microliters). All groups received the same antibiotic treatment as the control group. The animals were killed on the 5th day. Inflammatory index, area and perimeter of the wounded corneal zone, and corneal transparency were evaluated.. No significant differences in the inflammatory index were found between the treatment groups and the control group after 72 h. Significant differences (p < 0.001) were observed at 24 h in groups 3-5 when compared with the control group. Planimetry showed significant differences in group 4 when compared with the other groups (p < 0.05). Corneal transparency study showed statistically significantly better values in groups 4 and 5, when compared with the other groups, including group 3 (p < 0.05).. The use of 0.5% DMU combined with 1% indomethacin can be considered an alternative to corticosteroid treatment in our experimental chemical corneal injury.

Antioxidant therapy in the treatment of experimental acute corneal inflammation.
To ascertain the effectiveness of topical antioxidant therapy on acute corneal inflammation, we have studied the effectiveness of topical treatment with a saline solution and with antioxidants such as 0.2% superoxide dismutase and 0.5% dimethylthiourea (DMTU) in a controlled experimental study. The evolution of the inflammatory process was evaluated by a multimodel approach, including computer-assisted planimetry of the corneal ulcer and infiltrate, ultrasonic pachymetry, luminol-amplified chemiluminescence and the study of corneal transparency by direct spectral spectrophotometry transmittance. The experimental model was a corneal ulcer created by a 60-second application of 1 N sodium hydroxide. Topical treatment with DMTU was shown to significantly improve all parameters tested, while superoxide dismutase reduced only the corneal ulcers. Antioxidant topical therapy with DMTU was shown to be efficient in reducing the inflammatory reaction that occurs during acute corneal inflammation. This suggests that antioxidant therapy could be considered as a complementary treatment in the pharmacological modulation of acute corneal inflammation.
