Periocular atypical mycobacterial infections

Area of Science:

• Ophthalmology
• Infectious Diseases
• Microbiology

Background:

• Periocular infections caused by atypical mycobacteria are rare.
• This study examines clinical characteristics and management.

Observation:

• Six patients with periocular atypical mycobacterial infections (Mycobacterium chelonae, Mycobacterium fortuitum) were identified.
• Risk factors included immunosuppression, nasolacrimal duct obstruction, foreign bodies, and recent surgery.
• Clinical signs may include subacute presentation, firm nodules, mild erythema, and minimal discharge.

Findings:

• Infections were associated with predisposing factors like foreign bodies and immunosuppression.
• Debridement, foreign body removal, and systemic antibiotics guided by susceptibility testing led to resolution.
• Specific clinical features can help differentiate these infections from acute bacterial causes.

Implications:

• Early recognition of clinical signs is crucial for suspecting atypical mycobacterial infections.
• Prompt surgical intervention combined with appropriate antibiotic therapy is essential for successful management.
• Understanding these associations aids in preventing and treating periocular atypical mycobacterial infections.
