A 55-year-old woman underwent endoscopic sinus surgery for chronic sinusitis.Postoperatively, she complained of blurred vision, diplopia, and an inabilityto move the right eye.
Dilated ophthalmoscopy performed the next day showed multiple deep blotretinal hemorrhages in the midfundus periphery with suspicion of cystoid macularedema. No exudates were seen (Figure 1 and Figure 2). No permanent visual loss resulted,as the hemorrhages resolved after a few weeks and the macula was spared. Theretinal hemorrhages were possibly related to venous stasis. There was no evidenceof proptosis, chemosis, anterior chamber activity, or increased intraocularpressure. Mild anisocoria was noted.
