Summary

Intravitreal injection of up to 2 mg of infliximab has proved to be safe in animal models (rabbits and primates). These studies have shown no evidence of intraocular inflammation or toxicity by clinical, electrophysiological, and histopathological examination for up to 90 days even with 3 repeated monthly injections. However, the study conducted by Rassi et al was the only one to report the development of severe intraocular inflammation in one eye out of 12 rabbit eyes at 90 days following 3 intravitreal injections (2mg monthly). Unfortunately, clinical studies conducted on patients, so far, have raised serious concern about its safety and adverse effects.

These clinical studies have shown various and inconsistent results in terms of the safety and efficacy of intravitreal infliximab. These studies were conducted on patients with refractory as well as naïve cases of age related macular degenerations choroidal neovascularization (AMD CNV), diabetic macular edema (DME), central retinal vein occlusion (CRVO), angiomatous malformations, pseudophakic macular edema, and uveitis. The doses used ranged from 0.5mg to 2mg. The initial study by Theodossaidis et al in 2009 did not report any intraocular inflammation in 3 patients receiving 2 intravitreal injections of 1 and 2 mg for refractory AMD CNV with 7 months follow up period.(8) Later several clinical studies have reported severe intraocular inflammation following intravitreal injections of infliximab in non-uveitic patients.These collected data have initiated a call for cautious use of intravitreal infliximab.

On the other hand, studies investigating intravitreal infliximab in uveitis patients have shown improvement in vision, reduction in macular thickness on optical coherence tomography (OCT), and reduction in inflammation. In this study, we have investigated the safety and efficacy of 3 consecutive intravitreal infliximab injections (1 mg/0.05 mL, 6 weeks apart) in carefully selected group of patients with refractory uveitis in Behcet's disease.
