Periocular and Intravitreal Steroid Use in Treatment of Behcet’s Disease-Related Uveitis
Behcet’s disease has an intractable chronic recurrent course and ocular involvement is one of the most important morbidity reasons. Systemic steroids and immunosuppressive constitute the basis of the treatment in ocular involvement. However, both the side effects and the necessity of high dosages for ocular penetration of the medications favors the local treatment options. Periocular injections (orbital floor and subtenon) in this manner are found to be effective as an adjuvant in the treatment of intractable disease, reducing the systemic dosage and preventing the recurrences. In the intravitreal route, the most commonly used is triamcinolone acetonide (IVTA) injection. With this route, local depot effect, rapid impact on the posterior segment, and retinal vasculitis, better outcomes in vitreous haze and macular edema can be achieved. However, complications like cataract and intraocular pressure (IOP) rise are commonly seen. Other options in the intravitreal route are Fluocinolone acetonide (Retisert®) and dexamethasone (Ozurdex®) implants. Ozurdex® becomes a suitable treatment option with its long-lasting effect and low side effect profile compared to IVTA. Although Retisert® seems effective with its action that might extend to 3 years, the necessity of surgery for implantation, and the high rate of cataract and glaucoma complications, it is not preferred frequently.
