Iatrogenic Erosion of Orbital Walls due to Expanding Hydrogel Explant.

Hydrogel scleral buckles are a hydrophilic explant that may lead to significant delayed complications. They can insidiously enlarge over decades and may mimic an orbital tumor or cyst. The authors report a case of an expansive hydrogel scleral explant in a previously eviscerated socket. A 58-year-old male presented with a 2-week history of severe pain in his left anophthalmic socket. And 31 years prior, he had sustained OS trauma and undergone a series of surgeries. Details of these procedures were unavailable; however, he had ultimately proceeded to globe evisceration. MRI revealed a large lobulated cyst-like orbital mass with internal calcification, which had expanded the left orbit with erosion of the medial wall, lateral wall, and roof. It extended to involve the ethmoid and frontal paranasal sinuses. He proceeded to a lateral orbitotomy, revealing the lesion to be an expanded hydrogel scleral buckle explant. Postoperatively, there was a significant improvement in his pain.
