Relationship of echographic findings with visual outcomes in post-cataract surgery endophthalmitis

Preoperative ultrasonography in postoperative endophthalmitis was correlated with outcome following vitrectomy. Final visual acuity <20/400 in 14% of eyes with mild/moderate vitreous opacities vs. 67% with dense vitreous opacities. More virulent isolates were found in 67% of eyes with dense opacities vs. 9% with mild/moderate opacities. Dense vitreous debris on ultrasonography was associated with infection by virulent organisms and poorer outcome.
