Intravitreal dexamethasone implantation in a Behcet’s disease patient with macular edema, vasculitis after cataract surgery

Purpose: To report a case of macular edema and retinal vasculitis treated with intravitreal dexamethasone implantation in a Behcet’s disease patient after cataract surgery. Case summary: A 26-year-old male with Behcet’s disease, without recurrence of uveitis for 3 months, underwent phacoemulsifi-cation and posterior chamber intraocular lens implantation for a cataract in the left eye. The preoperative best corrected visual acuity (BCVA) of the left eye was 0.15. At day 1 after surgery, his BCVA was 0.4, and slit lamp examination of his left eye revealed a mild anterior chamber reaction. At 1 week after surgery, he presented with left vision impairment, his BCVA was 0.04, and mild inflammation was observed in both the anterior chamber and the vitreous in his left eye. Unilateral macular edema was confirmed with optical coherence tomography, and fluorescein angiography revealed retinal vasculitis on the fovea and peripheral retina. Intravitreal dexamethasone implantation was performed in his left eye, 1 month after treatment, the macular edema and retinal vasculitis had improved, and the BCVA of his left eye was 0.8. Conclusions: In patients with Behcet’s disease, intravitreal dexamethasone implantation can be an effective treatment option for macular edema and retinal vasculitis after cataract surgery.
