Purpose: To study the efficacy of intravitreal interferon alpha-2b for endotoxin-induced uveitis. Materials and Methods: A total of 36 rabbits were randomly allocated to one of the three groups: (1) received interferon plus balanced-salt solution; (2) received lipopolysaccharide (LPS) plus interferon; and (3) received LPS plus balanced-salt solution. Intraocular inflammation was evaluated by slit-lamp biomicroscopy (standardization of uveitis nomenclature grading), binocular indirect ophthalmoscopy (BIO) score, and histopathology. Results: Group 2 showed significantly lower mean (±standard deviation) anterior chamber reaction than Group 3 (3.1 ± 0.9 vs. 3.8 ± 0.4) on day 1 postinjection, lower vitreous cells on days 1 through 7 (day 1: 3.1 ± 0.9 vs. 3.8 ± 0.4; day 3: 2.1 ± 1.6 vs. 3.8 ± 0.4; day 7: 1.9 ± 1.3 vs. 3.6 ± 0.7), and lower BIO score on days 1-7 (day 1: 3.3 ± 1.2 vs. 4.4 ± 0.7; day 3: 3.0 ± 1.4 vs. 4.3 ± 0.9; day 7: 2.4 ± 1.4 vs. 3.7 ± 1.2). The protein content of anterior and vitreous aspirates was lower in Group 2 than 3 (1618.5 ± 411.4 vs. 2567.3 ± 330.8 and 2157.0 ± 283.3 vs. 3204.6 ± 259.5, respectively). Conclusion: Intravitreal interferon alpha-2b was effective in controlling endotoxin-induced uveitis.
