Mycotic endophthalmitis caused by Penicillium sp. after parenteral drug abuse
American Journal of Ophthalmology
|September 15, 1985
Abstract:
A 30-year-old man developed endophthalmitis three weeks after an intravenous injection of hydromorphone hydrochloride. Penicillium species was recovered from a vitreous aspirate. Treatment with amphotericin B and flucytosine resulted in documented sterilization of the vitreous. At a six-month follow-up examination, the visual acuity of the involved eye was still limited to light perception.
Insights
Intravenous drug use can lead to serious eye infections like endophthalmitis. Prompt antifungal treatment may sterilize the eye but visual outcomes can remain poor.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Intravenous drug abuse is a known risk factor for various infections.
- Endogenous and exogenous endophthalmitis can result from systemic or localized infections.
- Fungal endophthalmitis, though less common, poses a significant threat to vision.
Purpose of the Study:
- To report a case of fungal endophthalmitis caused by Penicillium species following hydromorphone hydrochloride injection.
- To describe the clinical course and treatment outcomes of this rare condition.
Main Methods:
- A 30-year-old male patient presented with endophthalmitis symptoms.
- Vitreous aspirate was collected for microbiological analysis.
- The patient was treated with intravenous amphotericin B and oral flucytosine.
Main Results:
- Penicillium species was identified as the causative agent of endophthalmitis.
- Antifungal therapy led to the sterilization of the vitreous humor.
- Despite treatment, the patient's visual acuity at six months was limited to light perception.
Conclusions:
- Fungal endophthalmitis following intravenous hydromorphone injection is a severe complication.
- Aggressive antifungal treatment can achieve microbial clearance but may not restore visual function.
- This case highlights the critical need for awareness and preventative strategies regarding intravenous drug use and associated ocular infections.
