Abstract
Purpose :
Our study aim to evaluate the epidemiology of endophthalmitis cases related with penetrant ocular trauma, visual acuity during endophthalmitis and one year after, the presence or absence of intraocular foreign body (IOFB), the material of intraocular foreign body, the treatment and to establish prognostic factors in these cases
Methods :
Retrospective study that analyzed epidemiological data of patients who underwent emergency sector evaluation and intravitreous or anterior chamber collect with endophthalmitis hypothesis and compatible history of ocular penetrant trauma from January of 2012 to January of 2017. Data from vitreous and anterior chamber analysis was obtained from register of Ophthalmology and Microbiology Laboratory and epidemiology and ophthalmological analysis from medical records
Results :
During the period, 420 patients had endophthalmitis suspicion and underwent vitreous or anterior chamber materials analysis. 30 patients (7.12%) had compatible history of penetrant trauma with intraocular foreing body; the mean age was 42.26 years (minimum of 11 years and maximum of 80 years); All the patients were male and 11 patients (36.66%) had the right eye affected, and 19 patients (63.33%) the left eye. The time from injury to intravitreal material collect varied between 1 day after trauma (36.66%), between 2 and 7 days (43.44%), between 7 and 14 days (10%) and 15 days after trauma (10%).
Among the 30 samples, 20 (66.66%) showed positive culture. 12 were positive for Staphylococcus coagulase-negativa (40%) and 3 were positive for Bacillus cereus (10%). The others positive cultures showed variable microorganisms, such as Lactococcus lactis, Pseudomonas fluorescens, and the very rare Sphingomoas paucimobilis.
We also analyzed the composition of injury-causing object, with metallic injury presented at 22 traumas (73.33%).
About the Inital Best Corrected Visual Acuity, 5 patients presented between 20/20 and 20/400 (16.66%), 12 patients at Hand Motion (40%), 7 patients with Light Perception (23.33%) and 1 with No Light Perception (3.33%).
One year after the trauma and endophthalmitis, 10 eyes presented NLP (33.33%), 2 eyes with LP (6.66%), 6 eyes with HM (20%) and 6 patients better than 20/400.
Conclusions :
This is the first Brazilian study that evaluate endophthalmitis cases after ocular trauma with intraocular foreign body, evaluated in a tertiary hospital.
