Abstract
Intravenous drug use (IVDU) is a known risk factor for endogenous endophthalmitis. Endogenous fungal endophthalmitis (EFE) is emerging as a common problem among this community. We describe the management and visual outcomes of acute IVDU-associated EFE. A prospective consecutive case series of 19 patients presenting with presumed acute IVDU-associated EFE from 2001 to 2007 to the Royal Victorian Eye and Ear Hospital was included. All data were collected in a standardized manner. Outcome measures included visual acuity, microbial profiles, and vitrectomy rate. Nineteen cases of IVDU-associated EFE were identified. Eight of these (42%) were men, and the mean age was 32.7 years (SD ± 8.0 years). Presenting visual acuity ranged from 6/6 to perception of light, with 58% having a visual acuity of 6/48 or less at presentation. Thirteen (68.4%) were culture positive with all cultures identifying Candida species, and 52.7% underwent vitrectomy. Fifty percent of subjects overall achieved a final visual acuity of 6/18 or better. Men demonstrated improved visual acuity when compared with women (P = 0.04). Age had no effect on final acuity. Intravenous drug use is a significant risk factor for developing EFE. Good visual outcomes can be achieved with early treatment, often with intravitreal therapy alone.
