The authors started the study before these new protocols were reported. Switching mid stream would prevent comparison between the early and late MRIs. No patient with intracanalicular involvement, with or without intraorbital optic nerve enhancement had complete recovery. Worst prognosis - lesions acutely located in both intraobital and intracanalicular optic nerve segments. Bigger lesions do worse.
Lesions involving the bony canal have a worse outcome.
The study shows promise and should be repeated with a larger sample size using present day imaging techniques. May Extracapsular cataract extraction with posterior chamber intraocular lens implantation was performed in five phakic eyes filled with silicone oil following vitreoretinal surgery. Silicone oil migration was prevented during surgery using an anterior chamber maintaining system and a self-sealed corneoscleral tunnel incision. No silicone-related complications were found, including silicone oil migration into the anterior chamber. There were no difficulties visualizing the peripheral retina during funduscopy.
