[The ultrasound findings in posttraumatic endophthalmitis].
The aim of this study was to evaluate the ultrasound findings in eyes with endophthalmitis following penetrating injury and to establish unfavorable predictive signs of this serious disease. In a retrospective study we evaluated findings in 7 eyes of 7 patients followed up because of posttraumatic endophthalmitis at the Department of Ophthalmology, School of Medicine, in Olomouc, Czech Republic, EU, during the period September 1999-December 2004. The mean age of the patients was 37.3 years (range 22-49 years). The mean duration of the period between the injury and the formation of the endophthalmitis was 8.4 days (range 1-21 days). The visual acuity at the time of admittance was very low; it ranged between light perception and 1/60 (0,016 or 20/1200). All patients underwent diagnostic-therapeutic pars plana vitrectomy with vitreous samples taken for microbiological examination and intravitreal antibiotic application. The final visual acuity (VA) ranged from 1/60 (0,016 or 20/1200) to 6/12 (0.5 or 20/40), so it was very variable and that gave us the possibility to follow the connection between the final VA and seriousness of the penetrating injury, and also with the interval between the emergence of the endophthalmitis and beginning of its treatment. During the ultrasound examination, the presence of membranes in the vitreous body, posterior vitreous detachment, thickening of the choroid, detachment of the choroid and detachment of the retina were of concern to us. Membranes were present in the vitreous in 5 eyes. Without membranes detected by the ultrasound, there were 2 eyes; in both of them the final VA was better than 6/36 (0,1667 or 20/120). The posterior vitreous detachment was detected in 3 eyes, and not detected in four eyes. We didn't find any connection between the final VA and posterior vitreous detachment. The thickening of the choroid was present at the ultrasound examination in all seven eyes. The detachment of the choroid was not found in any eye. The retina was detached in two eyes. In three eyes only, the final central VA was better than 6/36 (0.1667 or 20/120). In two of them, the intraocular foreign body was found and in both the bacteria Staphylococcus epidermidis was detected. In the third eye, the soil bacteria Enterococcus and Klebsiela were cultivated. The ultrasound findings in these three eyes are identical only in the term of thickening of the choroid, similar to other eyes. In two of them no membranes were detected by ultrasound and no posterior vitreous detachment was found. The ultrasound examination in eyes with endophthalmitis after penetrating injury is specific in particular because of the mechanism of the injury. In contrast to the cases of the postoperative endophthalmitis, no prognostic unfavorable sings in the ultrasound examination can be strictly identified.
