Rights and Permissions

An interesting postoperative complication was noted after a routine retinal detachment surgery with scleral buckling with pars plana vitrectomy and silicone oil injection. Anterior segment examination on the 1st postoperative day showed multiple small nonemulsified silicone oil globules, giving a fish egg appearance. Such an appearance is not seen routinely in the immediate postoperative period.

Keywords: Anterior chamber, fish egg appearance, nonemulsified, silicone oil

  Case Summary Top

A 65-year-old male patient presented to us with a sudden loss of vision in the left eye with best-corrected visual acuity of finger counting close to the face. Both eyes were pseudophakic. Posterior segment of the left eye showed total rhegmatogenous retinal detachment. The patient underwent left eye scleral buckling with pars plana vitrectomy and silicon oil injection. Surgery was uneventful. Slit-lamp examination on the 1st postoperative day showed multiple fish egg appearance of silicon oil in the anterior chamber [Figure 1].

  Discussion Top

Migration of silicone oil into the anterior chamber commonly occurs as a large globule or as multiple fine bubbles when it is emulsified.[1] It can cause raised intraocular pressure, pupillary block, or causing anterior displacement of iris diaphragm, leading to angle closure glaucoma.[2] Long-term complication is corneal endothelial toxicity.[3] Avoiding overfilling of the silicone oil and careful base dissection to avoid damage to the zonules can prevent this complication. Our patient had normal intraocular pressure, so the oil was left in situ and removed during silicone oil removal after 3 months.
