A rare case of Nocardia endophthalmitis, an intraocular infection, occurred in an immunosuppressed patient due to chronic steroid use. Prompt treatment with antibiotics and surgery led to a stable outcome, highlighting the importance of considering this in similar cases.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Endogenous endophthalmitis is a severe intraocular infection.
- Immunosuppression, particularly from chronic steroid use, increases susceptibility to opportunistic infections.
- Nocardia species are aerobic actinomycetes known to cause opportunistic infections.
Purpose of the Study:
- To report a rare case of endogenous Nocardia endophthalmitis.
- To highlight the association between chronic steroid use and this serious intraocular infection.
- To emphasize the diagnostic and therapeutic considerations for Nocardia endophthalmitis in immunosuppressed individuals.
Main Methods:
- A case report methodology was employed.
- Clinical presentation, ophthalmic examination findings, and microbiological cultures were documented.
- Treatment involved a combination of intravitreal and oral antimicrobial therapy, along with surgical intervention for retinal detachment.
Main Results:
- A 79-year-old female presented with decreased vision and floaters.
- Ophthalmic findings included severe anterior chamber inflammation, vitreous opacities, and retinal detachment.
- Vitreous cultures confirmed Nocardia farcinica infection without evidence of systemic spread. The patient achieved a stable condition post-treatment.
Conclusions:
- Nocardia endophthalmitis is a rare but serious condition.
- It should be considered in the differential diagnosis of intraocular infections in immunosuppressed patients, including those on steroids.
- Early diagnosis and appropriate management are crucial for favorable outcomes.
