Accidental Intralenticular Injection of Ozurdex® for Branch Retinal Vein Occlusion: Intact Posterior Capsule and Resolution of Macular Edema

Abstract

Purpose. We present a case of accidental intralenticular injection of Ozurdex implant in a patient with macular edema secondary to branch retinal vein occlusion. Method. A case report. Results. Intravitreal dexamethasone implant injection had been performed for macular edema due to left superior temporal vein branch occlusion to the left eye of a 78-year-old male patient. The slit-lamp examination 85 days later revealed that the dexamethasone implant was intralenticular. The best-corrected visual acuity (BCVA) was 0.16 on the Snellen chart. Cataract surgery was decided on for the cataract as there was no anterior chamber inflammation, the intraocular pressure (IOP) was normal, and the macular edema had resolved. Uneventful phacoemulsification within the bag intraocular lens placement was performed. Conclusions. Accidental intralenticular Ozurdex injection is an extremely rare complication. The surgeon must decide whether to continue to observe or intervene immediately when such a complication is encountered. Cataract surgery can be planned if the macular edema has resolved and a cataract has developed. It is important to evaluate the posterior capsule with ultrasound biomicroscopy and Scheimpflug imaging before the cataract surgery to ensure a safe surgical procedure.
