An unexpected complication in bilateral acute iris transillumination: Cystoid macular edema

A 47-year-old male presented with bilateral 4 + circulating pigment in the anterior chamber, diffuse iris transillumination, dilated pupils unresponsive to light, and high intraocular pressure (IOP) levels in both eyes. Visual acuity and IOP improved bilaterally with topical steroid and antiglaucomatous therapy. In the 10(th) month, bilateral cystoid macular edema (CME) was developed and resolved after subtenon triamcinolone injections. CME recurred after cataract surgery in the right eye which was treated with intravitreal dexamethasone implant injection. CME was recurred in the left eye and treated with intravitreal dexamethasone implant at the same setting with cataract surgery. CME can be seen in the course of bilateral acute iris transillumination (BAIT). This is the first BAIT case presenting with bilateral CME.
