Abstract

Objective::
To review the presentation, pathophysiology, diagnosis, and management of endogenous endophthalmitis in the setting of our regional and national opiod crisis with increased rates of IV drug use.

Abstract:

Purpose: From 2000 to 2014, the United States experienced a tripling in number of opioid overdose deaths. As of 2015, New Hampshire has one of the highest age-adjusted rates of death due to drug overdose at 34.3 per 100,000 persons. We investigated clinical characteristics of injection drug use (IDU) versus non-IDU endogenous endophthalmitis (EE) at Dartmouth-Hitchcock Medical Center (DHMC) during the opioid epidemic.

Methods: A retrospective chart review identified EE cases from January 2012 to December 2016 at DHMC via International Classification of Diseases (ICD-9, ICD-10) codes 360.0*, 360.1*, H44.0*, and H44.1*. Patient demographics, IDU history, microbial data, and clinical courses were recorded and analyzed.

Results: Fifteen patients with EE were identified, of which 9/15 (56.3%) had a history of IDU. Reduced vision was the most common presenting symptom in all IDU (9/9) and most non-IDU (5/6) patients. Compared with non-IDU patients, IDU patients were younger (31 vs 63 years, P<0.001) and had fewer co-morbidities. There was a trend for IDU patients to delay seeking care compared with non-IDU patients (24.7 vs 2.0 days). IDU patients demonstrated significantly more improvement in visual acuity after intervention than non-IDU patients. Non-IDU cases were more likely to present during hospitalization or shortly after discharge and less likely to undergo surgical intervention because of more frequent resolution of vitritis.

Conclusions: Patients with IDU-related EE were younger, ambulatory, and presented later than non-IDU related EE patients. Importantly, IDUrelated EE patients were more likely to experience improved vision with treatment than non-IDU related EE patients. IDU patients represent a younger and healthier subset of the EE population and may regain vision upon prompt recognition and treatment.
