Risk Factors for Culture-Positive Endophthalmitis after Repair of Open Globe Injuries

Purpose: To investigate the possible risk factors and prognosis of initial no light perception (NLP) in pediatric open globe injuries (POGI). Procedures: This retrospective, comparative, interventional case-control study included 865 eyes of POGI patients presenting to a tertiary referral ophthalmic center from 1 January 2011 to 31 December 2015. Eyes were divided into two groups: NLP group included eyes with initial NLP, and light perception(LP) group included eyes with initial LP or vision better than LP. Results: The following risk factors were significantly related to initial NLP: severe intraocular hemorrhage (OR=3.287, p=0.015), retinal detachment (RD) (OR=2.527, p=0.007), choroidal damage (OR=2.680, p=0.016) and endophthalmitis (OR=4.221, p＜0.001). Choroidal damage is related to remaining NLP after vitreoretinal surgery (OR=12.384, p=0.003). At the last visit, more eyes in the NLP group suffered from silicone oil–sustained status (OR=0.266, p=0.020) or ocular atrophy (OR=0.640, p=0.004), and less eyes benefitted from final LP (OR=41.061, p＜0.001) and anatomic success (OR=4.515, p＜0.001). Conclusion: Severe intraocular hemorrhage, RD, choroidal damage and endophthalmitis occurred more often in POGI with initial NLP. Choroidal damage was the major factor related to an NLP prognosis. Traumatized eyes with initial NLP could be anatomically and functionally preserved by vitreoretinal surgery.

Open Globe Injuries

Introduction: Endophthalmitis is the most dreaded complication of ocular trauma and knowledge of the microbial contaminants is essential to start empirical antibiotic therapy. Purpose: To determine incidence of contamination after open globe injuries (OGI) in our setup and to identify the spectrum of microorganisms contaminating open globe injuries. Material and methods: A prospective study including 50 consecutive eyes of open globe injury over a period of two years was conducted. Intra-operatively, 4 - 5 samples were taken from the inferior conjunctival sac and anterior chamber at the beginning and end of the open globe injury repair. Any abscised tissue or foreign body was also sent for culture sensitivity. A vitreous tap was taken from eyes with posterior segment trauma with signs of endophthalmitis. Results: Microbial cultures were positive in13 eyes (26 %). The microbial spectrum included Aspergillus species in 45.6 %, Alternaria in 15.2 %, Curvularia in 15.2 %, Staphylococcus aureus in 7.6 %, Bacillus species in 7.6 %, and Streptococcus pneumoniae in 7.6 %. Of these 13 eyes, nine eyes developed clinically evident frank endophthalmitis during follow-up. Overall, endophthalmitis developed in 20 eyes (40 %). There was a significant association between the initial contamination and development of endophthalmitis (p < 0.05). 53 % of culture positive cases achieved ambulatory vision compared to 73 % of culturenegative cases. Conclusion: Initial contamination was seen in 26 % of OGI cases. Aspergillus (fungus) was the commonest contaminant. There was a strong correlation between the initial contamination and development of endophthalmitis. Culture-negative cases had a trend towards better final visual outcome than culture-positive cases. Close follow up of cases showing contamination following OGI is recommended.
