Objective: Review and analysis of ultrasonografic data of patients with endophthalmitis following cataract surgery who were treated by us between 2000- 2005 (6 years).
Methods: We conducted a retrospective analysis of data and ultrasonographic findings of 86 patients with endophthalmitis following cataract surgery. 81 patients have reported ultrasonographic data. We evaluated type of surgery, time of onset of endophthalmitis and different ultrasonografic findings like organization of opacities in the vitreous, membranes formation, posterior vitreous membran detachment, detachment of choroidea and/or retina, choroidal abscess or granuloma, swellowing of optic nerve and thickness of the posterior wall.
Results: During the study period acute endophthalmitis following cataract surgery developed in 41 eyes, subacute in 25 eyes and late developing endophthalmitis in 20 eyes. As a tertier referal center 63 patients were admitted for treatment from other institutions. Ultrasonografic findings like thickness of the posterior wall was reported in most of the cases. Detachment of the choroidea was reported in 3 eyes, of the retina in 4 eyes, of retina and choroidea in 6 eyes. Membranes formation in 23 eyes (28%); dense vitreous opacities were detected in 9 eyes. Two findings of initial echography was associated with acute and subacute endophthalmitis: dense vitreous opacities and detachment of posterior vitreous limiting membran. The posterior wall thickness (mean±SD) was found greater in acute (1.51±0,34 mm) and subacute (1.62±0,35 mm) cases compared to late developed (1.47±029 mm), but the difference was not statistically significant (p>0.05, Mann-Whitney non-parametric test).
Conclusions: Ultrasonografic findings like thickness of the posterior wall and dense organization of the vitreous can be useful in the clinical evaluation, predictation and treatment of postoperative endopthalmitis.
