Hydrogel (Miragel®) scleral explant, late orbital complication

INTRODUCTION: The hydrogel Scleral Buckle is a soft and pliable subtype of buckles which has been used to repair retinal breaks and detachments externally. This case represents an unusual late orbital complication of the implant. CASE REPORT: A 70 years old male patient presented with drooping right upper lid and eye misalignment, associated with foreign body sensation and discomfort. The patient underwent scleral buckle surgery for a rhegmatogenous retinal detachment 32 years before his presentation using a hydrogel MIRAgel® explant. Orbital imaging showed a large cystic lesion in the superolateral quadrant of the orbit indicating a fluid-filled explant. DISCUSSION: In patients who were treated with hydrogel MIRAgel® explant for retinal breaks or detachments, detailed ophthalmic history, particular past eye surgery history, and examination, orbital imaging, and good clinical documentation. Serious orbital and neurological conditions need to be ruled out carefully. CONCLUSION: Late orbital complications of hydrogel MIRAgel® explant might develop late after surgery and might represent a diagnostic challenge for ophthalmologists.
