Summary
This case report details delayed-onset endophthalmitis caused by Mycobacterium goodii following cataract surgery. Prompt diagnosis and treatment led to a favorable visual outcome despite requiring intraocular lens removal.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Cataract surgery is a common procedure with a low risk of endophthalmitis.
- Delayed-onset endophthalmitis can present with varied etiologies.
- Mycobacterium species are uncommon causes of post-surgical infections.
Observation:
- A patient developed delayed-onset endophthalmitis one month after uneventful phacoemulsification and intraocular lens (IOL) implantation.
- Clinical signs included eye redness, pain, hypopyon, and decreased visual acuity.
- Vitreous biopsy cultures identified Mycobacterium goodii as the causative agent.
Findings:
- This is the first reported case of delayed-onset postcataract endophthalmitis caused by Mycobacterium goodii.
- DNA sequencing confirmed the bacterial identification.
- The patient required IOL explantation but achieved a final uncorrected vision of 20/40.
Implications:
- Mycobacterium goodii, a rapidly growing mycobacterium, can cause severe intraocular infections.
- Effective antimicrobial therapy, potentially including newer fluoroquinolones, is crucial.
- This case highlights the importance of considering atypical organisms in refractory endophthalmitis.
