The use of intravitreal injections of corticosteroid (triamcinolone acetonide) appears to be a promising treatment for a variety of ocular diseases associated with inflammation. To date, the only drug available, 'Kenalog-40 Injection' produced by Bristol Myers Squibb, has not been formulated for intraocular use. This formulation when used intraocularly has been associated with cases of non-bacterial endophthalmitis, which is thought to be due to the presence of benzyl alcohol and/or polysorbate 80. Both are suspected irritants.
