Published: March 2012

Purpose: To report the clinical presentations, antibiotic sensitivities, management, and outcomes of Enterobacter endophthalmitis.

Methods: This is a retrospective, consecutive, noncomparative, interventional case series. The medical records of culture-proven Enterobacter endophthalmitis cases from the endophthalmitis registry between January 1995 and March 2006 were reviewed.

Results: Enterobacter was the causative agent in 36 culture-proven cases. The causative event was cataract surgery in 11 and trauma in 25 patients. The presenting visual acuity was light perception in 26 eyes (72.2%). Polymicrobial infection was detected in 7 patients (19.4%). Enterobacter organisms were most sensitive to ciprofloxacin (n = 34; 94%), followed by amikacin (n = 31; 86%) and ceftazidime (n = 28; 78%). In postoperative endophthalmitis, final visual outcome of ≥20/200 was achieved in 3 patients (27%) and of ≥5/200 in 5 patients (45%). The eyes became phthisical in 3 patients (27%) and evisceration was carried out in 1 patient. In posttraumatic endophthalmitis, final visual outcome of ≥20/200 was achieved in 5 patients (20%) and of ≥5/200 in 7 patients (28%). The eyes of 11 patients (44%) became phthisical and evisceration was carried out in 1 patient.

Conclusion: Enterobacter organisms are mostly susceptible to ciprofloxacin, amikacin, and ceftazidime. Despite this coverage, the visual outcome is often poor.

The optimal therapeutic intervention for pediatrics with optic pathway glioma (OPG) remained controversial in the literature. Recently, due to substantial adverse events (AEs) of chemotherapy and its impact on children's lives, the efficacy of other options has been investigated. Bevacizumab (BVZ) is an anti-vascular endothelial growth factor (VEGF) agent that alters the lesion microenvironment.

To assess the efficacy of using a nylon suture as a stent in the PreserFlo MicroShunt (PMS) lumen to prevent postoperative hypotony, 59 eyes that underwent PMS implantation with follow-up for > 6 months were analyzed. Patients were divided into no intrastenting (NST) and intrastenting (ST) groups, with the ST group subdivided into 9 - 0 nylon suture fully placed (9 F), 9 - 0 nylon suture placement in only half of the lumen (9 H), 10 - 0 nylon suture fully placed (10 F), and 10 - 0 nylon suture placement in only half of the lumen (10 H). The distribution was as follows: 23 eyes in the NST group, 10 in the 9 F group, 9 in the 9 H group, 11 in the 10 F group, and 6 in the 10 H group.
