Optic nerve compression as a late complication of a hydrogel explant with silicone encircling band

Blog Article

Purpose: To present a complication of compressive optic neuropathy caused by a swollen hydrogel explant and posteriorly displaced silicone 100w products encircling band.Observations: A 72-year-old female patient presented with progressive visual loss and a tilted optic disc.Her medical history included a retinal detachment in 1993 that was treated with a hydrogel explant under a solid silicone encircling band.Visual acuity had decreased from 6/10 to 6/20 and perimetry showed a scotoma in the temporal superior quadrant.

On Magnetic Resonance Imaging (MRI), compression of the optic nerve by a displaced silicone encircling band inferior nasally in combination with a swollen episcleral hydrogel explant was observed.Surgical removal of the hydrogel explant and silicone encircling band was uneventful and resulted in improvement of visual acuity and visual field loss.Conclusions and importance: This tenga flip orb is the first report on compressive optic neuropathy caused by swelling of a hydrogel explant resulting in a dislocated silicone encircling band.The loss of visual function resolved upon removal of the explant and encircling band.
